ABOUT

s The invention relates to the field of computer technology and can be used for the operational control of the number of visitors to a site, such as a store. According to the main author. St. No. 658584, a device is known for automatically recording visitors, including its two illuminators with photodetectors, whose outputs through the visitors' directional recognition unit are connected to the counters of incoming and outgoing visitors and to a reversible binary counter, a clock pulse generator, a trigger, a waiting generator, summing the counter, the subtractive binary counter, the elements AND, the element ILINE, while the outputs of all bits of the reversible counter are connected to the first inputs of the elements AND, the output of the clock pulse generator pulses are connected to the second inputs of the And elements and to the single trigger input, the outputs of the AND elements are connected to the inputs of the subtractive binary counter, the outputs of which through the OR element are NOT connected to the zero input of the trigger, the output of the trigger is connected to the input of the waiting generator, the outputs of which are connected to the input of the summing the counter and the input of a sequential reset of the subtractive binary counter 1. The known device does not provide an alarm for an increased number of visitors to the object for a certain time lapse that does not allow for the adoption of operational measures to increase the capacity of the object, for example, by introducing an additional cash desk in the store. The purpose of the invention is to expand the functionality of the device by monitoring and signaling an increased flow of visitors. This goal is achieved by introducing a frequency divider, a delay element, additional counters and a detector, a standby generator output connected to the input of the first additional counter, the output of which through a second additional counter is connected to the input of the detector, the trigger output through the delay element connected to the reset input of the first additional counter, the output of the generator of clock pulses through the frequency divider is connected to the reset input of the second additional th counter. The drawing shows a functional diagram of the device. The device contains two illuminators 1 and 2, the light fluxes 3 and 4 of which illuminate the photodetectors 5 and 6. The outputs of the photodetectors are connected to block 7 recognizing the direction of movement of visitors, the outputs 10 and 8 of which are connected to the counter 10, the number of incoming visitors, reversible binary counter 12. The outputs of the triggers of all bits of the reversing binary counter i2 are connected to the first inputs of the AND 13 elements, to the second inputs of which the output of the generator is 14 clock pulses. The outputs of the elements And 13 connected to the trigger inputs of the subtractive binary counter 15, the outputs of which are connected to the element OR NOT 16 connected to the zero input of the trigger 17 reset, a single input of which is connected to the generator. 14 clock pulses. A single trigger trigger output 17 is connected to the input of delay element 21 and the input of a standby generator 18, the code of which is connected to the reset input of the subtractive counter 15, the input of the summing counter 19 and the input of the first additional counter 20: the allowable number of visitors with the setting module of the counting module, a reset input which is connected to the output of the delay element 21, and the output is connected to the input of the second additional counter, 22 cycles of operation with exceeding the permissible norm .1 with the setting unit of the counting module, the output of which is connected to the signaling device 23, and input sat Cpd wasp ene yield divider 24 frequency dividing ratio setting device, the input of which is connected to the output of oscillator 14 clock pulses. The device works as follows. When visitors enter and exit the premises, they intersect the light fluxes 3 and 4. Photo sensors 5 and 6 emit consecutive signals to the block 7 for detecting the direction of movement of visitors, and at its corresponding outputs 8 and 9 signals appear that enter counter 10 the number of visitors entering the premises is entered into the counter 11 by the number of visitors entering the inputs of the binary reversing counter 12. The clock generator 14 through the elements And 13 connects the outputs of the triggers of the binary reversible counter 12 to all the inputs of the triggers of the subtractive binary counter 15, which captures the received code, while the generator 14 of the clock pulses translates the trigger 17 of the reset to one state. The signal from Trig P triggers a standby generator 18, the pulses of which are fed to the input of the subtractive binary counter 15 and are taken into account by the output counter 19 and the first additional counter 20 of the allowable number of visitors. After the input of the counters 15, 19 and 20 receives the number of pulses corresponding to the binary code recorded in the subtractive counter 15 from

a reversible counter 12, an impulse appears at the input of the OR-NOT 16 element, setting the reset trigger 17 to the zero state, which puts the standby generator 18 into a decelerated state and includes a delay element 21, which after a specified time less than the clock cycle time generator 14, resets the additional counter 20 of the allowable number of visitors. If the number of pulses issued by the waiting generator 18 exceeds the counting module of the counter 20, then the latter generates a signal to the second additional counter for 22 operation cycles exceeding the permissible rate.

Each next pulse generator 14 clock pulses summarizes the number of visitors in the store, with the contents of counter 19, while exceeding the number of visitors with a given value counter 20 of the permissible number of visitors generates a pulse into the counter 22 cycles of operation with exceeding the permissible rate. If for a given time interval the number of pulses exceeds the value of the counting module of counter 22, then a signal arrives at its output to the detector 23. The time interval during which the permissible number of visitors is monitored is determined by the divider 24 associated with the generator output 14 clock pulses. When the predetermined time interval, determined by the division factor of the divider, ends, the latter generates a reset signal to the counter 22 of the number of operating cycles exceeding the permissible rate and sets it to its initial state. Then the test cycle repeats.

The specified test time is determined by

T,

where - frequency generator 14 clock pulses;

m is the division factor of the splitter 24 frequency.

If during time T the number of operating cycles exceeding the permissible norm is greater than the counter module 22, the signal from the latter is sent to the detector 23 and indicates that it is necessary to increase the capacity of the institution. This will allow to take operational measures to reduce the load on the staff and improve the quality of customer service.

The positive effect of using this device is to provide an indication of an increase in the number of visitors to the facility over a certain period of time, which allows for the adoption of operational measures to increase the capacity of the facility.
