Abstract
ABSTRACT OF THE DISCLOSURE
A system for remotely programming a mine includes a programming device comprising a computer having a data memory storing data representing all functions required to control the mine once the mine is laid, a code word memory and a random number generator. An output device is connected to the computer for displaying the data contained in the data memory. An input device causes data stored in data memory to be displayed by the output device, requests the random number generator to generate random numbers corresponding to respective addresses in data memory under which selected functions displayed by the output device are stored, and causes the storage of the generated random numbers as code words, together with corresponding data memory addresses, in the code word memory. A transmitter is connected to the computer for providing contactless transmission of the contents of the code word memory. A programmable electronic unit in the mine includes a receiver tuned to the transmitter of the programming device and a second computer connected to the receiver. The second computer has a second code word memory for storing the contents of the transmitted code word memory, and a second data memory corresponding to the data memory of the programming device storing data identical to the data stored in the data memory of the programming device. The second computer correlates a subsequently received code word with a code word previously stored in the second code word memory so that the function in the second data memory stored under the address corresponding to the subsequently received code word can be carried out.

BACRGROUND OP THB INVENTION
The present invention relates to a sy6tem and method for programming a mine by means of a programming device which includes a microcomputer connected to a transmitter for contactless transmission of signals for reception by a mine equipped with a receiver tuned to the transmitter for receiving the signals and connected to a microcomputer-like electronic unit in the mine.
Such mine systems and methods are known which program mines before they are laid, that is, for the normally contactless transmission of data to control desired actions within the mine after it is laid, with the data being stored in a type of data memory within the mine.
For example, German Offenlegungschrift tlaid-open patent application~ No. 3,523,857 discloses a mine system of the above type in which data can be transmitted without contact from a programming device to one or a group of mines. The data are transmitted in the form of infrared signals through 2~00~4 the intermediary of one or a plurality of input devices to an individual mine or a group of mine~ before they are laid and are stored in a data memory in the mine or mines. This German patent application, however, does not discuss remotely programming the mines after they are laid.
German Offenlegungschrift No. 3,545,289 discloses a remotely programmable mine which accommodates in its mine housing a receiving unit as well as a programming unit. The mine itself includes two memories within an electronic unit, with a spoken word or sentence being stored in digitized form in the first memory when the mine is laid. A word or sentence transmitted to the mine or mines after laying is received in the mine by a receiver, is digitized and stored in a second memory and then compared with the word stored in the first memory. If there is coincidence between the words, the mine is to be secured again. The drawback of this device is the use of acoustic methods for remotely influencing the mines. It is generally known that due to the structure and operation of the human speech forming apparatus, a-speaker is hardly able to pronounce the same word (or the same sentence) completely identically several times in succession, even within a short time interval, that is identical in pronuncia-tion and inflection, etc. Thus, there inevitably exist differences between the spoken programmed word (or sentence) - ~0~06~
and the word (or sentence) transmitted later for remote actuation, particularly if this word iB lntended for a large number of mines and is possibly to be transmitted to th~
mine(~) through the intermediary of further transmitting means (e.g. a megaphone).

3,545,289 to operate in the desired manner, the accuracy of the compilation of the characteristics of the programming word must be reduced to such an extent that it considers all possible variations in the word with respect to pronuncia-tion, inflection, etc., during the subsequent remote trans-mission. If, perhaps, other persons than the speaker of the programming word are to be authorized to effect a later remote actuation, the accuracy in the compilation of the word characteristics must be further reduced.
Additionally, the use of words and sentences that generally will be taken from terms originating in the programming speaker's environment, harbors the danger that these words or sentences may inadvertently be generated in another connection and possibly be detectable for the mine(s). The programmable mine system intended for later remote program~ing as disclosed in Offenlegungschrift No. 3,545,289 is thus unable to meet the modern requirements for such mine systems with respect to accuracy, a 6 ~
reproducibility and security against deception for reliable, remote programming only by friendly ~Eorces.
~Y~M~B~ QP TH~ INYENTION
It i5 therefore an ob~ect of the present invention to provide a novel programmable mine system which avoids the above-described drawback of programmable mine systems of this type and with which it is possible to reproducibly and remotely program a mine in a secure manner to prevent deception and without the danger of inadvertent actuation.
The above and other objects are accomplished according to the invention by the provision of a system for remotely programming a mine, comprising: a programming device remote from the mine, including: a computer having a data memory storing data representing all functions required to control the mine once the mine is laid, a code word memory and a random number generator for generating random numbers upon request; output means connected to the computer for display-ing the data contained in the data memory; input means connected to the computer for causing the data stored in the data memory to be displayed by the output means, for request-ing the random number generator to generate random numbers corresponding to respective addresses in the data memory under which selected functions displayed by the output means 2 0 ~
are stored, and for causing the storage of the generated random numbers as code words, together with corresponding data memory addresses, in the code word memory: and transmit-ter means connected to the computer for providing contactless transmission of the contents of the code word memory: and a programmable electronic unit for placement in the mine, including: recelving means tuned to the transmitter means of the programming device for receiving the contactless trans-mission of the transmitter means; and a second conputer connected to the receiving means and having a second code word memory corresponding to the code word memory of the programming device for storing the contents of the code word memory transmitted by the transmitter means, a second data memory corresponding to the data memory of the programming device storing data identical to the data stored in the data memory of the programming device, and means for correlating a code word received subsequently by the receiving means with a code word previously stored in the second code word memory for identifying a function in the second data memory stored under the address corresponding to the subsequently received code word.
~ he particular advantage of the mine programming system according to the invention is that the use of a random number generator in the programming device for the generation 20~3~
of code words makes the probabillty of the coincidence of code words with terms from the operator's environment unlike-ly. Thus, the danger is very low that such a code word, once formed, would inadvertently be generated and transmitted by other machines, even enemy machines during a later passaqe.
Moreover, the complete generation of code words ln the programming device is able to take place exclusively in the interior of the machine, without the respective code words being displayed, so that even the programming operator has no knowledge whatsoever of the code word or code words that were generated. Thus, the generation and later transmission of code words is secure against deception.
Another advantage of the mine programming system according to the invention i8 the use of identical com-ponents, such as code word memories and data memories, inthe programming device as well as in the mines, with addi-tionally the data memory of each mine receiving the same fixedly programmed information at the same addresses as the programming device. Thus, it becomes possible to assemble a simple, ætandardized configuration, possibly in modular form, which makes it possible to safely link together the mines as well as the programming device.
Since, according to the invention, all functions required for controlling the mine, once it has been laid, are .
2 ~
stored in the form of data, it i8 po~slblo to address not only one information (that is, a single action in the mine) by means of a code word, but, if nec~ssary, a code word generated in the random number generator may also be associated with a precisely defined linkage of individual data, while precisely specifying their hierarchy in the program run.
According to another aspect of the invention there i~
provided a method of programming a mine by a remote pro-gramming device which includes a computer having a datamemory for storing data corresponding to all functions required to control the mine once the mine is laid, compris-ing: displaying, on a display connected to the computer, a listing of all data stored in the data memory by actuation of a keyboard input connected to the computer; selecting and marking at least one of the displayed data by way of the keyboard input; generating a respectively different code word comprised of a random number for each one of the marked data;
storing the code words together with data memory addresses belonging to the individual marked data in a code word memory; and transmitting, by a contactless transmission initiated by way of the keyboard input, the contents of the code word memory of the programming device for reception by the mine.

The method of programming mines according to the present invention with the aid of ~ programmlng device allows simple operation and manipulation even for relatively unskilled users.
The mine programming system according to the invention will now be described and explained in greater detail with reference to the accompanying drawings.

DXTAILE~ DESCRIPTION OF THE PaEFERRFD EMBODIMENT
Referring to Figure 1, there i8 shown a programming or operator device 10 which includes a microcomputer 12.
Microcomputer 12 comprises a central processing unit (uP) 14 which serves as a central controller, an operating memory 16, a data memory 18 which is configured as a read-only memory (ROM), a random number generator 20 and a code word memory 22. A keyboard 30 is provided for the manual input and actuation of program operations within microcomputer 12. An output unit, visible to the operator, in the form of a _ g _ -- 2~03G~
display 32, preferably an LCD dlsplay comprising only a ~ew lines, i8 built into programming device 10.
Data memorv 18 contains all of the data reguired for controlling the mine in the form of functions Jl to Jn and possibly linkages of individual functions as respectively independent data Ji. Each function or linkage of function~
Jl to Jn has a fixed address Al to An in memory 18.
Programming device 10 has a further output in the form of a contactless transmission by way of a transmitter 28, preferably a high freguency ~HF) transmitter, coupled to a microcomputer 14 through an analog-to-digital (A/D) converter 26 and a signal processing unit 24. -Referring to Figure 2, there is shown a programmableelectronic unit for placement in a mine 40 and which, like programming device 10, includes a microcomputer 42. Micro-computer 42 includes a central processing unit (uP) 44, an operating memorv 46 as well as a data memory 48 which, like data memory 18 in programming device 10, is a read-only memory and contains the same data Jl to Jn at the same addresses Al to An. Microprocessor 42 of mine 40 further includes a comparator 50 and a code word memory 52 which has a configuration corresponding to that of code word memory 22 of programming device 10. Signals sent to mine 40 are received by a receiver 58, preferably an HF receiver, and - . . .. .. . - .. . .
`-` 2~5~
sent to an analog/digital (A/D) converter 56, which cor-responds to A/D converter 26 of programing device 10, and then to a signal processing unit 54 from where they go to microcomputer 42.
Microcomputer 42 has an output connected to a detonation and safety unit (ZUSE) 60 which is in turn connected for triggering a warhead 62 in a known manner.
The sensors, evaluation circuits and energy supplies customarily employed in a mine such as this, as well as in the programmable device 10, are known per se and thus are not shown here for the sake of simplicity.
The operational sequences within the mine programming - system according to the present invention take place as follows:
In order to program one or a group of mines, an operator calls up, by way of keyboard 30 of the operational program-ming device 10, the contents of data memory 18, that is, all data Jl to Jn, and displays them on output display 32 in the form of a list or the like. Then the operator selects from the list of displayed data, all those data which correspond to actions that are to be remotely actuated after the mine 40 has been laid. The selected data Ji, or the selected group of data, is marked by the operator by way of an input to keyboard 30. A renewed keyboard input now initiates a 2 0 5 ~ 6 ~
coding process in which random number generator 20 generates certain code word for each address A~ of the selected data Ji-Once this process is completed, the addresses and their 5 associated code words are stored in code word memory 22. A
display of the code words on display 32 may possibly be omitted.
To actually program mine 40, an input to the keyboard causes the contents of code word memory 22 in progranming 10 device 10 to be transferred by means of central processing unit 14 to signal processing unit 24 and then this informa-tion is transmitted through the intermediary of analog/digi-tal converter 26 to transmitter 28. Each mine 40 that is to be programmed by means of the code words generated in 15 programming device 10 has in the meantime been switched to a ready to receive mode and thus receives the signal trans-mitted by transmitter 28 in its receiver 58 and transmits it via analog/digital converter 56 to signal processing unit 54, and by way of central processing unit 44, stores the 20 received signals in code word memory 52, after which the mine is ready to be laid.
If after these mines 40 have been laid, a desired action is to be initiated in the mines, for example, making them secure again or resetting a detonation delay time, the -- . . . . . .
. '- 2~3~31J~
operator ls able to display on display 32 of programming device 10 the selected data stored in code word memory 22 by using keyboard 30 as an input device. For safety reasons, the code words associated with the individual selected data should not be displayed. After again selecting and marking the action desired in mines 40 by the keyboard input, the code word or words belonging to the selected function (action) is taken from code word memory 22 and sent to transmitter 28 from where it is transmitted. Each mine 40, which is ready to receive, picks up the signal in its receiver 58 and sends it in the manner already described to central processor 44. The received code word is now transferred by central processor 44 to comparator 50 which compares it with all code words stored in code word memory 52. If the transmitted code word should coincide with one of the code words in the code word memory, the address Ai belonging to the code word for the respective information Ji is read out of code word memory 52. By way of this address Ai, the corresponding action present as data Ji is read out of data memory 48 and is transmitted via central processing unit 44 to the detonating and safety device 60 which, in turn, is able to directly address warhead 62.

Obviously, numerous and additional modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically claimed.
Additionally, the use of words and sentences that generally will be taken from terms originating in the programming speaker's environment, harbors the danger that these words or sentences may inadvertently be generated in another connection and possibly be detectable for the mine(s).
