SU452028A1 - Device for remote signaling the choice of the address of the object - Google Patents

Description

one

This invention relates to the field of telemechanics.

The remote signaling devices are known that contain a communication line to both ends of which a transmitter and receiver are connected, at the control point - a pulse distributor, the first output of which is connected via a key to the transmitter input, a coincidence circuit, one input of which is connected to the second output of the pulse distributor, the other the input is to the output of the receiver, and the output is to the input of the indicator, at the executive point there is a coincidence circuit, one input of the first of which is connected to the first output of the pulse distributor, and the other input - from the output a receiver input of the second coincidence circuit connected to the second output pulse distributor, and the output - to the transmitter.

The proposed device is characterized in that it contains at the execution point a memory block, the input of which is connected to the output of the first coincidence circuit, and the output to another input of the second coincidence circuit.

1 This allows you to do without a source of flashing light, t. E. significantly simplify the device and increase the reliability of its work.

The drawing shows a functional diagram of the proposed device.

The device contains a communication line 1, at the control point — a pulse distributor 2, a key 3, a transmitter 4, a receiver 5, a coincidence circuit 6 and an indicator 7, at an executive point — a pulse distributor 8, a coincidence circuit 9, 1 O, a transmitter 11, a receiver 12 and memory block 13.

Works the proposed device as follows.

When the key 3 of the control unit is closed on the pulse of the pulse distributor 2, which is assigned to the preparatory television signaling, the transmitter 4 receives the signal of the preparatory command through the communication line 1. At the execution point, this signal is sensed by I-NIC 12 and transmitted to one of the inputs of the coincidence circuit 10. At the same time,

its other input receives a signal from the corresponding output of the pulse distributor 8, confirming the choice of the address of the telecontrol object. When these signals coincide, a voltage pulse appears at the output of the coincidence circuit 10, which is memorized by the memory unit 13. At the pulse distributor 8 clock assigned to the preparatory television signaling, the coincidence circuit 9 is implemented, and the information signal about the choice of the object address is transmitted through the transmitter 11 to the link 1. At the control point, this signal is sensed by the receiver 5 and transmitted to one of the inputs of the matching circuit 6. Its other input receives a signal from the corresponding output of the impedance distributor lsov 2. In case of coincidence of said signal at the output of the coincidence circuit 6 po5shl a voltage pulse, Ko tory indicator lights 7 for a time equal to the duration of a newly coincidence signal. The cyclicality of the ignition of the box 7 is determined by the period of occurrence of the signals at the outputs of the pulse distributors 2.8 related to the channel of the digital teleservice.
