Description

The invention relates to an automatic control technique, namely, devices for monitoring alarm sensors. .

The aim of the invention is to expand the field of application of the device by increasing the number of controlled objects while maintaining the number of communication lines.

FIG. 1 shows a diagram of the device; in fig. 2 is a diagram of a signal analysis unit; in fig. 3 is a diagram of the display unit (signals); in fig. 4 is a diagram of a pulse distributor; in fig. 5 - time diagram of the device.

The device for monitoring the state of objects comprises the signal analysis block 1, the indication block 2, included in the information processing unit 3, the anode switch unit 4, the amplifier unit 5, the cathode switch unit 6, the generator 7 pulses, the distributor 8 pulses, the inputs 9 blocks 1 analysis of signals, output 10 of block 4 of anode switches, output 11 of block 5 of amplifiers, output 12 of block 6 of cathode switches, switching contacts 13 and thyristor optocouplers 14, forming the control matrix 15.

The signal analysis unit 1 is made of a decoder 16, a NOT element 17, and an OR element 18.

The display unit 2 is made of display elements 19, triggers 20 and 21, a reset and lock key 22.

The distributor 8 pulses made of counters 23-26 and elements And 27.,

Device d / 4 control of the state of objects works as follows.

From the device from outputs 10 (block 4 of anode switches). 11 (block 5 amplifiers) and

S3 Ј

12 (cathode switch unit 6), respectively, are sent to the control matrices 15 serial polling pulses from the distributor 8 pulses. The number of polling pulse outputs is determined by the number of groups of control matrices 15, the number of columns of control matrices 15 and the number of control matrices 15 in the group. Polling pulses are generated at the outputs of the counters 24, 25 and 26. The state of the switching contact 13 of the sensor is determined when the polling signals of a high level coincide at the outputs of the LED of the optocoupler 14, a low level on the corresponding row of the control matrix 15.

From switching outputs, contacts

The 13 sensors of the control matrices 15 are removed paraphase (when the installation is healthy) signals that are fed to the inputs of the 9 corresponding signal analysis blocks 1. The signals input to input 9. are identified by signal analysis units 1 as follows:

code 01 - switching operation

pin 13 of the sensor is missing;

code 10 - switching contact 13 of the sensor

triggered; code 11 - tire or chain breakage

switching contact 13 connections

to the tire;

Code 00 - one of the buses (or both) is grounded.

Codes 00 and 11 indicate mounting faults in the signal collection network.

Codes received at input 9 are decrypted by the decoder 16 included in the signal analysis unit 1. The violation signal is generated at the output of the NOT element 17 of the signal analysis unit 1 and triggers the corresponding trigger 20 in one of the display units 2. Codes 00 and 11 are additionally classified as a malfunction of the switching contacts of the 13 sensors, and a signal is generated at the output of the element OR 18, causing the corresponding trigger 21. The trigger 21 is activated in the second polling cycle under the condition of cocking in the first poll cycle of the trigger 20. Thereby eliminating The possibility of false triggering of the trigger 21 due to the bounce of the switching contacts of 13 sensors when they are switched at the time of the action of the corresponding strobe pulse.

Let us assume conventionally that in the first control matrix 15 from one of the sensors 1-2 (the first digit is the row number, the second is the column number) the connection to the vertical bus is broken, and in the fourth control

Matrix 15 sensor 3-4 worked. Then, when polling, in the first conditional cycle, triggers of 20 blocks 2 with addresses 1-2 (first node 3) and 3-4 (fourth node 3) are indicated, indicating a fault in the corresponding switching contacts of 13 sensors, and in the second poll cycle, trigger 21 block 2 with address 1-2 (first node 3). indicating a faulty installation. The triggering of the flip-flops 20 and 21 is performed at the time of gating their inputs with pulses coming from the outputs of the elements 27 of the distributor 8 pulses.
