FIG. 1 shows a functional diagram of a part of the device installed at a control point; in fig. 2 is a diagram of a part of a device mounted on a movable object.

At the control point, the device contains an alternating voltage generator 1, a first frequency divider 2, a shaper of 3 pulses, a counter 4 and a pulse distributor 5, a block of 6 keys, a second element OR 7, a block of 8 emitters, a block of 9 receivers, the first key 10 , frequency filter 11, detector 12, shaper 13 start-stop pulses, third key 14, shaper 15 pulses, chronizer 16, trigger 17, second key 18, register 19, memory block 20, first element OR 21, second frequency divider 22 , the third driver 23 pulses, the stabilizer 24 for example voltage source 25 and a voltage block

26 input information consisting of the remote

27, a delay element 28 and a decoder 29.

On a mobile object, the device comprises a receiver 30, a first key 31, a frequency filter 32, a detector 33, a first frequency divider 34, a switch 35, a power supply 36, a first pulse shaper 37, a trigger 38, a delay element 39, a random time generator 40, a second key 41, alternating voltage generator 42, second driver

43 pulses, a third key 44, a second frequency divider 45, a register 46, a counter 47, a decoder 48, a memory block 49, an OR 50 element and an emitter 51.

The device works as follows.

(applied to public transport).

Upon arriving at the stopping point, the driver presses the key on the remote control 27. This connects the supply voltage to the device components (Fig. 1).

The driver 23 and the divider 2 go to the state "1 at the output. Thus, all control points (doorways) are polled with the specified poll peer. The divider 22 is in the state "O, block 20 receives a signal

preparing it for operation, register 19 is zeroed, trigger 17 goes to the state "O. The signal from the console 27 is fed to the source 25, then (after a time equal to the time of entry

the device component mode) the signal from the delay element 28 is fed to the decoder 29, from where the placement signals are sent to the key inputs of the key block 6 via the communication bus. Placement signals are supplied only to keys corresponding to the open door. Generator 1 sends a signal to the first keys of key block 6, to the first input of the divider 2 and to the first input of the divider 22.

When a signal appears at the output of the splitter, the driver 3 generates a pulse coming from its direct output to the input of the demand signal distributor, from whose output it enters the input of the corresponding key of block 6. The signal "1 from the direct output of the driver 3 passes to the first input of the element OR 7

and its output to the second inputs of the block keys

6 keys. The key (for example, 6.1) is open and the radio pulse is emitted by the emitter (for example, 8.1) modulated by the signal, and the one-shot 3 switches to the "O on direct output and to the" 1 on the inverse, while the enabling signal is fed to the first the input of the key 10. If the object is not in range of the signal from the radiator, for example, 8.1, then the divider 2 again sends a signal to the input of the imaging unit 3, and the described procedure is repeated with another key (for example, 6.2). and another radiator (8.2). Thus, all control points are interrogated (doorways).

For example, in one of the doorways (for example, in the first) for vils object. After the interrogation radio pulse is emitted by the emitter 8.1, the receiver 30, located on the object, receives this signal, the trigger 38 is in the "O" state, so the inverse output is state 1 and the key 31 is open. The signal from receiver 30 passes to filter 32, where a signal is extracted at a frequency (this prevents penetration into the input of the interference detector 33), the frequency is converted into a sending of direct current. This premise translates divider 34 into the state "1. The signal from the output of the divider 34 is fed to the input of the switch 35, from which the supply voltage is applied to the components of the device. The signal is fed to the driver 37, at the output of which a signal is generated to transfer the counter 47 to the state "O."

When the supply voltage to the generator 40 comes, it starts working. Its signal sets the trigger 38 to the state "1", thus the signal "O, key 31 locked" appears on the inverse output. The same signal is fed to a driver 43, which produces a short pulse. On the leading edge of the pulse, the code recorded in register 46 is recorded. The same pulse, hitting the first input of element 50, produces a signal "1 at its output. Key 44 for the duration of the pulse is open. The signal from the output of the generator 40 is also fed to the first input of the key 41, allowing the signal from the generator 42 to pass, the signal from the output of the key 41 is fed to the divider 45 and to the first input of the key 44. As long as the latter is open, a radio pulse modulated by the frequency emitter 51 is emitted. This radio pulse is received by one of the receivers (9.1 - 9.6) of block 9 and is fed to the second input of the key 10. As the inverter output of the driver, the signal "1, key 10 is open. The signal passes to the input of filter 11, where a signal with a different frequency is extracted (thereby preventing the penetration of interference with a different frequency). The signal from the output of the filter 11 is fed to the detector

12, and from its output to the first input of the imaging unit 13 and to the second input 14. After the DC signal from the detector 12 arrives at the first input of the forwarder 13, the pulse from the first output of the imaging unit 13 is fed to the input of the imaging unit 15. It produces a pulse of a given duration is also intended to interface with the components of the device in question. Signal "1

0. The former 15 passes to the second input of the element OR 7. At its output, the signal "1 opening key, the code combination of which is in the distributor (for example, 6.1), appears. Radiation of a radio pulse occurs, the start coinciding with the leading edge of the starting parcel.

The pulse from the output of the imaging unit 15 is fed to the input of the chroniser 16. Code

The Q time recorded from the chroniser 16 enters block 20, thereby recording the time of interaction of the object. The pulse duration from the imaging unit 15 is longer than the period of the pulse generator of the chroniser 16.

5 If there were several objects in range of a signal from emitters (for example, 8.1), the first one that captures the communication channel is an object whose time interval is shorter (it will respond earlier). This eliminates collisions (simultaneous transmission of information). For those objects that are simultaneously acting on a signal from an emitter (for example, 8.1) that have not produced a signal "1 at the output of the generator 40 (Fig. 2), the trigger 38 is in the state" O therefore the key

 31 is open. And the signal coming from the emitter (e.g. 8.1) of the object of the object that captures the communication channel arriving at the leading edge of the starting parcel of the device passes through the filter 32, the detector 33 and sets the divider 34 to the state "O, this signal switches off the power supply through the switch 35 (U) from the components of the device (Fig. 2), which returns to the initial state. These object devices are triggered again, like

5 has been described, on the arrival of the next polling pulse from the radiator (for example, 8.1), The device of the object that captured the communication from the output of the divider 45 receives signals to the clock input of the register 46 and to the information

 the input of the counter 47. The code recorded in the register 46 starts sequentially to the element OR 50, the output of which is fed to the key 44. The information parcels (the modulated signal and the unmodulated signal) are transmitted through the second radiator to the input of the first receiver (for example, 9.1 ). The starting package is formed by the shaper 43 and code fluctuations recorded in block 49. The pulse duration from the shaper 43 is chosen such that after it ends, the signal "1" is saved at the output of the OR 50 element, due to the presence of this signal at the register 46 output. Fig. 2) there is a pause (null parcel). Of which is used to synchronize the transmitted information from the object device to the device receiving this information. Upon the arrival of the trailing edge of the starting parcel, the driver generates a pulse at its second output (Fig. 1). The impulse of the second output of the imaging unit 13 (Fig. 1) arrives at the second input of the trigger 17 and transfers it to the state "1. At the inverse of the output of the trigger 17, the signal "O, which locks the driver 13, appears, and it becomes insensitive to the incoming information parcels. The signal “I from the direct output of the trigger 17 unlocks the keys 18 and 14. The information signals from the output of the detector 12 through the key 14 arrive at the information input of the register 19, to the clock input of which through the key 18 receives pulses from the divider 22. The code is overwritten into the register 19 from register 46. In the transmitted information, after the pause, there is always a service impulse of the unit. Upon the arrival of this pulse to the control output of the register 19, the trigger 17 enters the “O” state. The same pulse arrives at the first input of the element OR 21, from the output of which the signal goes to the control input of block 20. The information from register 19 is overwritten into block 21. On the falling edge of the register 19 pulse, divider 22 is zeroed, set to the state the divider 2 is set to the state "I, the driver 13 enters the initial state. Impulse "1 from the output of the divider 2 is fed to the input of the imaging unit 3, which again produces a pulse. The distributor issues another polling signal to the third input of the corresponding key.

(e.g. 6.2), and the described device operation cycle is repeated. At the same time, when the set value of the state code of the counter 47 (Fig. 2), equal to the amount of information transmitted, is reached, the output of the decimator 48 is the signal "1, which is fed to the input" Installation "O divider 34. The signal" O the output of the divider 2 through the switch 35 disconnects the supply voltage (Un) from the components of the device (Fig. 2). The signal from the decimator 48 is also fed to the input of the element when the time, the longer time the object leaves the signal zone from the radiator (for example 6.1), is

5 but less than the next time of interaction with a similar emitter (for example, 6.2 when the object leaves), element 39 generates a signal “1” which translates the trigger 38 (FIG. 2) to the state “O”, thereby the key 31 is opened from the inverse output of the trigger 38 , the device is ready for the next mark.

The frequency of the survey depends on the number of control and reset points.

Memory unit 20 may have a different structure. In the case of operation of the device in the loop of the automated control and information collection system, it has a control circuit, a random access memory, and a register of interface with external devices (for example, a vehicle device). According to the commands received via the junction register, the control circuit rewrites the accumulated information into external devices. During autonomous operation, the memory unit

5 may be a tape recorder.

The control circuit performs functions of checking information, for example, on the clarity and repetition of the same code, while the code is written only once.
