Description

FIELD OF THE INVENTION This invention relates to human control devices in man-machine, man-machine systems.

The purpose of the invention is to increase reliability.

Structural diagram of the proposed device is shown in the drawing.

The circuit contains an object number fixing unit 1, an object category code setting unit 2, memory blocks 3-5, a difference calculation block b, a timer 7, a memory block 8, the inputs of the latter are connected to the outputs of timer 7, and the group of its outputs is connected to the first the group of inputs of block 6, switch 9, comparison block 10, controller wake sensor 11, decoder 12, signaling device 13, and OR gate 14.

The device operates as follows.

When the train passes the checkpoint of the railway section by block 1, the train number is identified. In this case, the passage time of the control point is recorded digitally in block 8. The recording is carried out at the control input of the recording mode of this register according to the control command generated by block 1. In addition, the train number code is the address code of block 5. At the same time, information on the travel time of this train of this control point, planned by the schedule, is selected from the address cell , which enters block 6, to another group of inputs of which information is received from the outputs of block 8. The task of block 6 is to determine the time of lateness of a given train by the formula

eowa). From the output of this unit in binary form (log. 1, log. O), the control input of the digital switch 9 receives a signal about the connection of the first or second input. One input is connected to block 3, and the other to block 4. In blocks 3 and 4, information on the permissible delay time by type of train is recorded based on the recommended standards fixing the deviation from the traffic schedule. According to the control command of log.1, the output of the digital switch receives information from block 3, where the permissible delay time of the passenger train is recorded, and with log.O information from block 4, respectively, of the freight train. From the outputs of block 6 and the digital switch 9, information is fed through the information buses to the inputs of the comparison block 10, where the permissible lateness is compared with the real latency. If At Stflon, then at the output of the logical element OR there is a log. 1. If Dktdop, then the corresponding output of the comparison block will also have a log. 1, and at the output of element 14 - log.O. All these outputs are connected to the inputs of the decoder 12, to the free inputs of which the outputs of the sensor 11 are also connected.

The information received in the decoder 12 is decoded in a form convenient for controlling the operation of the signaling device 13,
