Vertical memorizer 130, the content of this manipulation memorizer can be programmed by communication unit 140, this communication unit and operating unit
40 are communicated by n control signal by operation interface 16.Both manipulation rule can have been stored also in handling memorizer 130
The alternate data for producing alternate data signal DE_S, DE_M can be stored.In this way, it is possible to make device 10 neatly
It is assigned in the request of change.
Additionally, operation interface 16 may be used for the data exchange between numerical control device 20 and position measurement apparatus 30
Time just allow amendment or determine mode and the scale of manipulation.This such as can by can run in operating unit 40 and
The computer program providing the menu setecting of different options is carried out.
Programmable module, such as FPGA(Field Programmable Gate is advantageously used as circuit arrangement 15
Array, field programmable gate array).This module can be reprogrammed at any time and therefore be optimally adapted to according to this
Change and/or the extension of the dirigibility of the device 10 of invention are made a response.It is particularly well-suited for equally filling as circuit
Put 15 be microcontroller because it also can reprogramming and be matched with the condition of change simply.The most logical
Cross operation interface 16 and carry out the programming of circuit arrangement 15.
Fig. 3 illustrates the data transmission sequence of the simplification for the operation principle according to apparatus of the present invention 10 is described.Especially
Eliminate the process by the interface signal in circuit arrangement 100 or a small amount of time delay that synchronization causes.Show from numeral
Controlling the transmission of the position requests order of device 20 to position measurement apparatus 30, subsequent position is measured equipment 30 and is sent current position
Put data to data control unit 20.In order to improve transmission security, design attitude request command the most redundantly, especially
Described position requests order is made up of the first command block C1 and the second command block C2, this first command block C1 and the second command block C2
Being formed by 3 the most respectively, wherein the second command block C2 repeats the first command block C1 the most in the same manner or on the contrary.The opposing party
Face, position measurement apparatus 30 is as response (as has already been mentioned above) two the positional value POS1 of transmission to position request command
And POS2, the two positional value has data relationship POS2=POS1+side-play amount each other.In position measurement apparatus 30 each other
Have independently produced positional value POS1 and POS2, thus numerical control device 20 can pass through comparison position value POS1, POS2 with
The mathematical relationship known to determine positional value POS1, POS2 generation and transmission whether be errorless.If it is determined that make mistake, then count
Word controls device 20 and must respond in a defined manner, such as by exporting alert notice or being set by stop position measurement
Standby 30 equipment run wherein (" safety stop ").
As for improving the addition thereto of transmission security, can pass through respectively CRC code end position value POS1,
POS2。
As the manipulation rule of above-described position requests order, deposit in apparatus 10: surveyed by position actually
That should replace to numerical control device 20 forwarding on the position of second position value POS2 that amount equipment 30 sends, that change second
Positional value POS2.Which therefore, handle rule to determine: must be at moment control interchangeable unit 120, in order to replace master data input
Signal DIN_M exports main alternate data signal DE_M as from data output signal DOUT_S.Equally in handling rule
It is determined that change second position value POS2 in which way.Protocol element provides main alternate data signal according to described regulation
DE_M。
Manipulation rule can also comprise arbitrarily other instructions, such as, is when order occurs for the first time or to go back in multiple times
It is even to perform manipulation when recognizing this order every time.It may also be determined that according to the formation of alternate data signal DE_M, DE_S
Regulation is differently to handle the most in the same manner or every time.
At this it should be understood that point out, handle rule and need not must correspond in Data Transport Protocol category by digital control dress
Put 20 orders being sent to position measurement apparatus 30.More precisely, from numerical control device 20 or also set from position measurement
The standby 30 each any information reaching device 10 or circuit arrangement 100 can correspond to one and handle rule.In simplest feelings
In shape, it is already possible to by the i.e. data of the use of clock signal transmit start be evaluated as corresponding to one handle rule
Information.
The first row of the data transmission sequence that figure 3 illustrates illustrates and arrives circuit arrangement 15 from numerical control device 30
The master forwarded to position measurement apparatus 30 from circuit arrangement 15 from clock signal TCLK_S or (in the case of negligible delay)
Clock signal TCLK_M.
Second row illustrates from data input signal DIN_S, should include command block C1 and C2 also from data input signal DIN_S
And pass through the first actuation unit 110 the most unchangeably as master data output signal DOUT_M at position measurement apparatus 30
Direction on forward.
In master data input signal DIN_M shown in the third line, this master data input signal DIN_M comprises position measurement and sets
The reply data of standby 30, especially positional value POS1 and POS2, terminates (not shown) with CRC code when necessary.
Finally, fourth line illustrates main alternate data signal DE_M, and this main alternate data signal DE_M is produced by protocol element 100
Second position value POS2 that is raw and that send by position measurement apparatus 30 for replacement in this example.Producing main alternate data
It is certainly contemplated that the need of CRC code during signal DE_M.
By selected by the second actuation unit 120 respectively data signal (or master data input signal DIN_M or
Main alternate data signal DE_M) as being transmitted to numerical control device 20 from data output signal DOUT_S.
Time flow is carried out as follows:
Activating after clock signal TCLK_S, first changing data direction.If it is assumed that from making in resting state
Can signal OEN_S be that actively to connect and instigate signal OEN_M to be passive connection, then protocol element 100 at moment t1 and
The first conversion time period U1 between t2 connects the most passively from enabling signal OEN_S and connecting instigator the most on one's own initiative
Can signal OEN_M.This conversion is carried out the most by stages, in order to avoid data collision.
From moment t2, carry out the transmission of the first command block C1, from moment t3, carry out the transmission of the second command block C2.
The transmission of the second command block C2 terminates at moment t4, and protocol element 100 can pass through comparison command block C1, C2 now
Whether the transmission determining order is errorless.
The latest at moment t4, protocol element 100 has enough information to be able to determine whether to carry out interface signal
Manipulation, say, that for described order whether as there is manipulation rule in this example.Handle rule or definition
In protocol element 100 or be stored in manipulation memorizer 130 in.It is also possible that this information of protocol element 100 is by grasping
Make unit 40 to be notified by operation interface 16 and communication unit 140.
Order transmission after, from moment t4 to moment t5 be the second conversion time period U2, this second conversion time
Change data direction, especially protocol element in Duan connect instigator energy signal OEN_M passively and connect on one's own initiative from enable
Signal OEN_S.
From moment t5, start to transmit reply data from position measurement apparatus 30 to numerical control device 20, first
Sending homing sequence START, this homing sequence is such as made up of start bit, some mode bits subsequently, these mode bits its permit
Permitted to infer the running status of position measurement apparatus 30.
After homing sequence SRART, from moment t6, transmit primary importance word POS1.
According to the manipulation rule for the current command, protocol element 100 is in moment t7 changes the second actuation unit 120
Switch element 122, thus from this moment replace master data input signal DIN_M as from data output signal DOUT_S to number
Word controls device 20 and exports by protocol element 100 according to handling the main alternate data signal DE_M that rule provides.
Original state is returned in moment t8, DTD, and protocol element 100.
