Description

one

The invention relates to a measurement technique that can be used both in vehicles to record passengers and in other areas where it is necessary to take into account the number of moving objects that have passed a certain section of the signal in a particular direction, for example in entertainment rooms, to account for transport. .

A device for counting the number of passengers is known, which contains sensors connected to the adjacent inputs of the direction analyzers, adders made on the triggers and AND and OR elements, the outputs of the OR elements are connected to counters, and the pulse distributor, the outputs of the direction analyzers are connected to one of the corresponding trigger inputs. , the other input of each of which is connected to the output of the AND element connected to the OR element, the first inputs of the AND elements are connected to the output of the corresponding triggers, and the second These inputs are with the corresponding outputs of pulse distributor I.

A disadvantage of this device is its complexity.

The closest technical solution to this is a device for counting the number of passengers, containing pairwise connected sensors, the first output of the first sensor of each pair is connected to the first input of the corresponding trigger of the first adder, the second outputs of the first sensors and the outputs of the second sensors of each pair of sensors are connected respectively the first and second inputs of the corresponding trigger of the second adder, the outputs of each trigger of the second adder are connected to the first input of the corresponding element I, the outputs of which n th merged with an input connected to the first input of the counter n down counter | 2j.

The disadvantage of this device is low speed, since the pulse distributor of this device does not provide registration of moving objects in the order of their passage through the controlled sections. The polling frequency of the monitored areas is large, however, the pulse distributor operates in such a way that it is forced to interrogate n areas that no moving objects pass through.

The aim of the invention is to speed the device.

The goal is achieved due to the fact that the element OR and the elements OR NOT are entered into the first adder of the device, the output of each of which is connected to the corresponding input of the element OR, the second input of the corresponding trigger, one of the inputs of the remaining elements OR NOT and the second input of the corresponding element And the second adder, the output of the element OR of the first adder is connected to the second input of the reversible counter.

The drawing shows a block diagram of the proposed device.

The device for counting the number of passengers contains sensors 1, .2, the first adder 3, including triggers 4, the elements OR NOT 5 and the element OR 6, the second adder 7, performed on the triggers 8 and elements 9, the reversible counter 10 and the counter P.

The device works as follows,

In the initial state, the triggers 4 of the first adder are in the zero state. At the same time, triggers 4 give out levels “1, which create at the outputs of the elements OR NOT HE 5 levels“ O. It is enough to do any of the requests from the first sensor 1 to register the relevant information, as the corresponding trigger 4 is re-routed and will issue the level "O, which will create the signal" 1 at the corresponding output of the element OR NOT 5. The signal "i from the output of the corresponding element OR - NOT 5 through the element OR 6 enters the summing input of the reversible counter 10, returns the trigger 4 to the initial state and opens the corresponding element AND 9. If the second input of this element And 9 is the unit potential from the corresponding trigger 8. then, from the output of the second adder 7, the signal “I will go to the subtracting input of the reversible counter 10 and to the sum” that connects the input of counter P. Since two opposite impulses were received at the inputs of the reversing counter 10, then the register aci event occurs only if the counter 10. The second input of the AND gate 9 will not be a single potential, a reversible counter () is registered event. Thus, the reversible counter 10 registers, for example, the number of passengers entered, and the counter and the number of passengers entering.

If, during this time, a request arrives at another input, it is recorded in the trigger 4. After resetting the previously activated trigger, the operation cycle of the device is repeated on the other input.

If requests are received simultaneously from two or more inputs, then the first adder 3 is spontaneously set to the state corresponding to one of these requests. After this request is completed, the others will be served in the same way.

When using this device, there is no need to survey areas through which mobile objects do not pass.
