Description

Devices are known for distant c; ion control of mobile objects in p, p, and field tests, containing sensors whose inputs are connected to the corresponding inaccessible contacts of the first contact field of each step finder, a time delay circuit, a block of alarms and switches. .

The purpose of the invention is to improve the accuracy of the device.

This is achieved by introducing a control time generator, a matching circuit, a trigger and a second time delay circuit into the device, the input of which is connected to the second contact field of the step finder.

The even and odd stationary contacts of the finder are interconnected, and the moving contact is connected to the power supply. The outputs of the first and second time delays are connected to the input of the control time generator, the output of which is connected to the first input circuit of the coincidence circuit, and the second input of the circuit is connected via the key to the moving contact of the first contact field of the step finder and through the diode to the first trigger input connected to the input and alarm device

The drawing shows the electrical circuit of the proposed device. The logic circuit is given for one step finder.

the number of which corresponds to the number of objects tested.

The device consists of silence sensors 1, which are installed along the motion path at equal distances between each other's OiT, step finders 2, keys 3 for connecting passable sensors to step finders and time delay 4, in addition the device contains a control time generator 5, diagram 6 matches, the trigger 7 and the output device of the alarm 8, which can serve as a relay. In the initial state, all step finders are located on the first contact.

When the object enters the polygon track to the sensor / behind, the corresponding key 3 is closed, and the searcher 2 begins to follow the movement of the object, preparing the circuit from the next sensor to the rotation mechanism. Also

happens and with subsequent objects.

Parallel to the finder coil 2, a 9 interval counter is connected, which counts the intervals between the sensors. The moving contact 10 of the second contact field, which contacts are connected through one, serves a voltage that, when the searcher 2 is moved, alternately delays 4. Delay outputs are connected to a single-input device. After a time delay expires a delay of 4 (one or a friend)

launches r & nerator 5, from the output of the KOTOpioro I-IA pulse travels to one of the inputs of circuit 6. To the other input of the circuit, a relatively high impulse is passed from the flow sensor. In the case of spasad, neither of these two pulses will appear on the output of circuit 6, deduction of t, p, and gger 7 in such a position that the output signaling device has failed. If the pulses at the input of the circuit 6 are not sanded and there is no sippal, the pulse from the sensor throws the trigger 7 and the output signaling device of the emergency mode is triggered. At the output of circuit 6, the counter 9 is connected, reading, only those intervals that are normal in normal mode.

Consequently, if an object with a doubled polygon exceeds the speed of the permissible limit, then it approaches the next sensor earlier than end of time 4. At this, searcher 2 makes next schag, one of the delay, stops counting by 4, and begins another . The generator 5 does not start, and a signal 6 does not appear at the output of the circuit, and the HIM pulse from the passage sensor throws the trigger 7 and turns on an emergency cryptograph.

If the tested object slows down the speed below the permissible limit, then in this case, after the end of holding time 4 the generator starts, the pulse from the sensor to the circuit 6 is not received for this period of time.

The trailing front impulse from one: the driver's | switch flushes trigger 7 and activates an alarm.

When an object moves at a speed whose oscillations lie within the allowable interval, the pulse from the next sensor arrives within I mpulse of the control time and at the output of circuit 6 the signal ud bp1 triggers at the position at which the output signaling device 8 o mc turns off. Counter 9 counts the interval of normal movement.

At the same time, the remote control device automatically begins to monitor each test object by cKOipocTiH, it doesn’t depend on when it goes to the track, and also to conduct a deterministic count of the number of I1Pter0101 traveled by it and the total number of intervals passed at a normal speed.

The whole scheme, except for the step finder and sensors, is performed on standard elements of the transistor logic and has an increased reliability.

In order to change the test mode of mobile objects in an aperture mode, it is possible to change the durations of the time delay pulses and the control time generator. In the particular case, this occurs due to a change in the resistance of the resistors, NOT the time delay circuit.
