Description

The invention relates to a measurement technique and can be used to control the movement and counting of moving objects, as well as to determine the direction of rotation and measure the number of revolutions of the object. . A device is known that consists of a phase shifter on four inverters, the outputs of which are connected to the inputs of the other four inverters through separation capacitors, triggers with separate inputs and two assemblies of four logic elements. The disadvantage of this device is that a change in the direction of passage of an object is produced when there is at least one input signal, while, for example, identifying the direction of movement of the heat transfer to the elements on the atomic lektrostantsi x is carried out only if the two signals on channels gamma and neutron radiation. . The closest in technical essence and the achieved result / to the invention is a device containing an acting element mounted on a moving object, two signal conversion channels made of series-connected sensors, a generator, a pulse shaper, a BANNER element, a trigger and a waiting multi vibrator, matching elements, elements And, delay lines and a generator of clock pulses, perceiving elements in which can be performed, for example, in the form of Hall sensors, to the output 's chains employing decoupling t ransformatory 23. The disadvantage of this device is its complexity caused by the presence of the whole number of different functional components, which leads to decrease in reliability. The aim of the invention is to simplify the device and increase its reliability. The goal is achieved by the fact that in the device for controlling the movement of an object, we have two sensors and two information channels, each information channel is equipped with two D-flip-flops, while the inverse output of the first sensor is connected to the D input of the first trigger of the first channel and C-terminal of the first trigger of the second the channel, the direct output of the first sensor is connected to D-BXO; the house of the second flip-flop of the first channel; the C-input of the second flip-flop of the second channel; the direct output of the second sensor is connected to the C-input of the second flip-flop of the first channel la AND D-input of the second trigger of the second channel, the inverse output of the second sensor is connected to the C-input of the first trigger of the first channel and the D-input of the first trigger of the second channel, and in each channel the direct output of the first trigger is connected to the R-input of the second trigger, and the inverse output of the second trigger - with the R-input of the first trigger. The drawing shows the functional diagram of the device. The device contains the first and second sensors 1 and 2 with direct and inverse outputs, the first and second d-flip-flops 3 and 4 of the first information transmission channel and the first and second D-flip-flops; 5 and 6 of the second channel of information transfer. The device works in the following way. Upon receipt from sensors 1 and 2 of positive pulses that are out of phase, for example, half the pulse duration switches to. the zero state is the first D-flip-flop 5 of the second channel on the positive edge of the pulse from the direct output of sensor 1, at this time at its D-BXO zero signal level. If the trigger is already in ets and state, it will be confirmed. At. switching this trigger to the zero state at its inverse output is at a logical unit level that ensures the zero state of the second D-flip-flop 6. of the second channel. Positive edge of a pulse from a direct output of the sensor; ka 2 the first D-flip-flop 3 of the first channel will be set to one, since its input L at this moment has a high potential from the direct output of sensor 1. At its input R at this moment there is a zero level from the direct output the second D-flip-flop 4 of the first channel and does not prevent the installation of the first D-flip-flop 3 of the first channel -t into one state. The second jl-flip-flop 4 of the first channel at this time the ns1 is in the zero state. This is its only possible steady state before the arrival of pulses from sensors 1 and 2. On the positive edge of the pulse from the inverse, the output of sensor 2 of the second D-flip-flop 4, the First channel will be set to one, since at this time it is at its D-input a high potential from the inverse output of sensor 2, and on the H-low there is a low potential from the inverse output of the first D-flip-flop 3 jiepBoro channel, previously set to b, the unit state. As soon as the second D-flip-flop 4 of the first channel is set to one.

signal from its direct post-Qg output. The device has a certain grapit on the R-input of the first D-flip-flop 3nitsa end of the later pulse of the first channel and sets it up completely, at the intersection of which the initial state is set. After that on. It is an object passing fact

inverse output of the first D-flip-flop in a certain direction. If in

The first 3 channels will be set to the sensor height until the intersection of this

Since the potential that enters the boundary is a change in the directional input R of the second D-flip-flop 4 for the first movement of the object, then the fact of the forward channel and returning it to zero escape is not established. If a

condition. Thus, at the output of the object crossed the border, and then an impulse is formed in the device's pattern. Yunil direction then set

When an object moves in a different direction, it travels in both directions. The operation of the device is similar to that of the device. The proposed device is different, but the impulse is formed on the surface by simplicity and high reliability.
