Description

Method and device for counting people entering and leaving public places

Technical field:

The invention relates to a method and device for counting people entering and exiting public places, which is used for counting the flow of people entering and exiting public places with doors, such as passenger cars, stations, docks, shopping malls and other places that need to be counted.

Background technique:

After searching, in the field of personnel flow counting, there is a Chinese invention patent application with application number 03115817.X, and its invention name is "passenger automatic counting instrument". This counter uses infrared rays arranged on both sides of the bus door. The method of the probe uses the logical sequence of people blocking the infrared probes in the process of going up and down to determine the number of people getting on and off the car, and judges the number of people according to the width and thickness of the human body. However, this device has obvious shortcomings: the counting is not accurate , the judgment of up and down is easily disturbed, it is difficult to adapt to the flow count of more than 3 people and the scope of application is small, the reason is: when 2 people are parallel and close to each other, it is easy to record 2 people as 1 person, especially when people go up and down at the same time When there are a lot of people, the detection signals of the infrared probes are likely to interfere with each other and cannot correctly distinguish between the upper and lower sides, and the arrangement of the infrared probes on both sides objectively determines that only 2 people can be judged. When there are more than 2 people, only two people will be recorded, so It is not suitable for the counting of large flow of people entering and leaving.

Invention content:

The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a method and device for counting the entry and exit of people in public places to accurately determine the direction of entry and exit of persons and the number of people entering and exiting at the same time, and has a wide range of applications.

The principle of the present invention is: when a person walks normally, due to the forward movement of the center of gravity of the human body, the rear heel is lifted first, followed by a kicking action on the forefoot, and the sole of the foot is separated from the ground in the order of heel-sole-toe, and this is done. The process of walking with one foot up, so in the process from kicking up to when the foot leaves the ground, the rear heel, rear sole, forefoot and toe are in a sequence in terms of the time when they leave the ground. For this physiological movement characteristic of human beings, we use self-made pedal sensors to detect the ground-off time of the heel, forefoot and toe and convert them into electrical signals to judge the direction of people's entry and exit. zone to record the number of people passing the pedal sensor.

In order to realize the above-mentioned purpose of the invention, the technical scheme of counting method of the present invention is:

(2), judge whether to open the door: when the single-chip microcomputer receives the door-opening signal, the door is opened;

(3), the single-chip microcomputer receives and stores the 1 and 0 data input by the pedal sensor;

(4), compare the data received this time with the data received last time, and judge which data has more 1s, and when the number of 1s is more, return to step 3, otherwise continue to execute downward;

(5), to pedal-type sensor array partition: the data input with adjacent column sensor is all 0 as the dividing line of pedal-type sensor array partition;

(6), the single-chip microcomputer receives and stores the 1, 0 data input by each partition sensor;

(7), Judging the entry, exit and quantity of personnel and storing: use the time sequence of all 0 data in the top row and bottom row of the non-zero data input by sensors in each partition to judge the entry and exit of people, and each partition represents One person, all the people who come in are stored in the memory of the number of people who entered, and all the people who leave are stored in the memory of the number of people who went out;

(8), judge whether the data input by each partition sensor is all 0: when not all 0, then return to step 6, otherwise continue to execute downward;

(9), judge whether to close the door: close the door when the single-chip microcomputer receives the door closing signal, when the door is closed, continue to execute, and return to step 3 if the door is not closed;

(10), the number of personnel entering and exiting is transmitted to a computer or a wireless data transmission terminal, and then returns to step 2.
