(54) DEVICE FOR RECEPTION AND TRANSMISSION OF TELEINFORMATION

one

The device for receiving and transmitting teleinformation belongs to the field of telemechanics, and can be used in the integrated dispatcher systems AJIH for monitoring and controlling the engineering equipment of housing and communal facilities.

For the purposes of dispatching engineering equipment of housing and public utility facilities, various systems and equipment sets are used, which allow receiving and processing information about the state of the controlled equipment of dispatch objects.

Devices are known that are designed to monitor and control dispersed objects, consisting of transmitting and receiving semi-sets connected by a multi-wire communication line. The transmitting semi-kit is made on keys, relays, switching elements, signal contacts, a switch, and DC and AC power sources. The receiving half set includes switching elements, keys, relay 1.

A disadvantage of the known device is a limited number of pivot points of controlled controlled points, connection with the control point, built on the principle of multi-wire connections.

The closest technical solution is a telemechanical dispatcher device, which contains on the transmitting side a control unit, address keys, a mode selection key, the first output of which is connected to the first input of the telemetry receiver, and the second to the encoder input, the third to the amplifier input, the first output which is connected to the speakerphone unit, the decoder, and there is a decoder on the receiving side,

5 whose output is connected to the first input of the switching and control unit, the first output of which is connected to the telecontrol object, the second input and output to the telemetry sensor, blocks

0 speakerphone 2.

However, the known device, when used for dispatching engineering equipment of housing and communal services, has

5 significant drawbacks limiting its use for dispatch purposes. In the known device, the number of connected controlled Points is limited, since

0 Each of Them is connected to certain trunk tires, and an increase in the number of controlled points causes an increase in the number of trunk tires. The use of a certain pulse sequence for coding an address and its transmission over an unconsolidated communication line imposes certain requirements on the noise immunity of the main communication lines and equipment1 When used in the communication method and the interaction of functional nodes, the amount of information transmitted from the monitored points is limited.

The purpose of the invention is to expand the functionality of the device, its circuit and constructive simplification, increase information capacity, increase the reliability and reliability of the processed information

For this purpose, a switch, an interrogation unit, an address signaling device, an AND element, an OR element, a delay block are entered into the device on the front side. The first outputs of the first and second address keys are connected respectively to the first and second addresses of the address alarm, the output of which is connected to the first input I. The second outputs of the address keys are connected respectively to the first and second inputs of the control unit, the first output of which is connected to the second input of the AND element, the output of which is connected to the first input of the OR element, the second input of which th coupled to the first output control switch through a delay unit. The output of the OR element is connected to the first input of the polling unit, the output of which is connected to the first input of the decoder. The fourth output of the mode selection key is connected to the input of the control key, the output of the encoder with the first input of the switch. The second outputs of the control key, amplifier, polling unit and control unit are connected respectively to the second, third, fourth and fifth inputs of the switch, the first, second and third outputs of which are connected respectively to the second inputs of the telemetry receiver, polling unit and decoder, the second output of the control unit s. connected to the sixth input of the switch. At the receiving side, a switch, code buses, a priority block, the first OR element, a remote signaling cell, are made on the switches, the encoder, the second OR element, the driver. The outputs of the switches are connected to the corresponding inputs of the encoder and the OR element, the output of which through the driver is connected to the corresponding input of the first OR element. The output of the encoder is connected to the first input of the switch, the inputs of the switches are connected in pairs and connected to the code buses. The outputs of the hands-free units are connected to the corresponding inputs of the unit, the first output of which is connected to the second input of the last switch of the remote signaling cell. The second output of the priority block is connected to the second input of the switch, the first output of which is connected to the second input of the switching and control unit, the third input and the second output of which are connected to the speakerphone unit. The outputs of the decoder are connected to the corresponding inputs of the switch. The switches of the receiving and transmitting sides are connected by a communication line. The third outputs of the address keys of the transmitting side are connected to the fourth inputs of the control point switches at the receiving side. The outputs of the control points are connected to the corresponding inputs of the address indicator on the transmitting side.

Consider the work of the proposed device in different modes.

In the initial state, the contacts of the technological switches b or the contacts of the calling devices of the loudspeaker communication are open. The line connection unit 2 ensures that the code side 4 of the receive side half complex has a positive potential of a common power source. The trunk lines 2 are disconnected from the receiving side of the half-bundle.

All controlled points in the system are connected in parallel to the main lines of communication. The number of control points in the system is not standardized. The number of communication lines remains unchanged.
