Definitions
- the invention relates to a remote supervision system for automatic supervision of tasks to be per- formed at several different working sites within a wide area.
- Cleaning firms for instance, have several working sites where their employees should go to perform their task at predetermined times on prede- termined days. Since the number of the working sites as well as that of the employees is great and the working sites and times vary greatly from day to day, it is extremely difficult to supervise the performance of the tasks at each particular site at the right time. However, it would be necessary to know imme ⁇ diately if the employee has not arrived at the working site due to a mistake or illness or for some other reason, so that another employee could be contacted and ordered to perform the task. Such a supervision, however, would require a full-time supervisor, in big firms several supervisors, and the supervision would nevertheless be unreliable and incomplete.
- the object of the invention is to provide a re ⁇ mote supervision system which carries out the super ⁇ vision automatically and reliably so that the super ⁇ vision staff can attend to other duties.
- a remote super- vision system which is characterized in that an interface unit connected to a telephone line and comprising means for activating the telephone line in response to a line signal from the telephone line, and means for converting DTMF (dual- tone multifrequency) tone pair signals received from the telephone line into digital codes, and a control unit comprising a real time clock, a memory including an expected report time set for the report of each task to be supervised, and means for comparing the time generated by the real time clock with the report times stored in the memory and for giving an alarm if the time generated by the real time clock is sub ⁇ stantially the same as or deviates by a predetermined period of time from the report time stored for each particular task and if the control unit has not re ⁇ ceived report of each particular task from the inter ⁇ face unit in the form of a predetermined digital re ⁇ port code.
- an interface unit connected to a telephone line and comprising means for activating the telephone line in response to a line signal from the telephone line, and means for converting DTMF
- the basic idea of the invention is that the tasks and the predetermined report times thereof are stored in the memory of the supervision system.
- the supervision system compares the stored report times to the real time continually and automatically. If the employee at the working site contacts the supervision system through the public telephone network and sends it a report code corresponding to a certain task, the supervision system acknowledges receipt of the report and does not give an alarm at the stored report time. On the other hand, if no report code has been received by the stored report time, the supervision system automatically gives an alarm which may be an output transmitted to a display unit or a printer, a sound signal, a combination thereof, or some other suitable alarm. Thereby the supervision staff attending to other duties can take the required measures for check ⁇ ing and adjusting the situation.
- the system is fully automatic and eliminates mistakes caused by human errors and omissions of tasks.
- the supervision data can be stored for long times ahead, and the supervision is not affected by daily variation in working sites, supervision times, employees, and the like.
- the supervision system according to the inven ⁇ tion can be connected to the book-keeping and invoic- ing systems of the firm, utilizing the customer data stored therein and correspondingly supplying these systems with information about the performance of the tasks.
- the supervision system comprises an interface unit 2 for connection to a telephone line Li of the public telephone network.
- the interface unit 2 comprises means for automatically activating the telephone line (forming a path for the loop current of the telephone line) and means for re- ceiving the DTMF (dual-tone multifrequency) tone pair signals from the telephone line and for converting it into a digital code.
- the last-mentioned is usually a dual-tone multifrequency (DTMF) receiver known in the art, which converts the received voice-frequency pair into a BCD number. Suitable receivers include model MT8870 of Mitel Inc.
- the digital code formed from the received tone pair signals is transmitted through a signal bus 6 to a control unit 1.
- the interface unit 2 may further comprise an impulse-type dialer or a dual-tone multifrequency (DTMF) transmitter for trans ⁇ mitting the dialled number to the public telephone network.
- DTMF dual-tone multifrequency
- Suitable dual-tone multifrequency trans ⁇ mitters include MK5089 supplied by Mitel Inc.
- the transmitter is thereby controlled by the control unit 1 through the bus 6.
- the bus 6 represents generally all control and data transmission buses and lines bet ⁇ ween the control unit 1 and the interface unit 2.
- the interface unit 2 may also include a voice synthesizer for communication with the employee via the public telephone network.
- the control unit 1 controls the operation of the supervision system in all respects. It contains a memory 4 in which all necessary data concerning the tasks to be supervised are stored, preferably at least task codes and report times.
- the control unit 1 further comprises a real time clock which generates an output indicating the real time.
- the time generated by the real time clock comprises at least the clock time, preferably also the date, and possibly the weekday.
- the control unit 1 further comprises means 5 for com ⁇ paring the output of the real time clock with the re ⁇ port times stored in the memory and gives an alarm if the predetermined report code has not been received through the interface unit 2 and the output of the real time clock 3 substantially corresponds to the re ⁇ port time stored for each particular task.
- the alarm can be given e.g.
- the control unit 1 may process the report code supplied by the interface unit 6 in various ways. For instance, the file stored in the memory 4 may not only include the working site and the report time but also a special data field called a flag which provides information about whether the report has been received or not. The flag may possess two states one of which indicates that the report is missing and the other that the report has been received.
- control unit 1 When the control unit 1 receives a report code from the interface unit 2, it changes the state of the flag stored in the memory 4.
- the comparing means 5 also check the state of the report flag when comparing the real time with the report time stored in the memory. If the report flag is set and the report code is received, the comparing means 5 do not give an alarm under any conditions.
- control unit 1 can be effected by means of a microcomputer, whereby the output unit 7 may be a display unit or printer connected to the microcomputer.
- the interface unit 2 in turn, may be an interface card enclosed in the same casing as the microcomputer.
- the comparing means 5 may be the processing unit of the microcomputer; the memory 4 may be the central memory or mass storage of the microcomputer; and the real time clock 3 may be a counter in a timer attached to the microcomputer, the real time and date being generated from the counting of the counter by a software. It is also possible that the employee corre ⁇ spondingly sends a report to the control system on leaving the working site, whereby the working time spent can be determined, which can be utilized in fix ⁇ ing the wages of the employee, pricing the task, etc.
- the supervision system can also be connected to the book-keeping and invoicing systems of the firm, obtaining information about the customers and pro ⁇ viding them with information about the working times and performed tasks.
- the book-keeping and invoicing system may be a book-keeping and invoicing program to be run in the same computer.
