Problems solved by technology
[0005] 1) Part of the data needs to be actively collected by the public security department, which is time-consuming and laborious;
[0006] 2) Some people work in cities without any registration, and the public security department cannot perceive it;
[0007] 3) The frequency of crowd flow is increasing, and there is a lack of means to grasp first-hand data in a timely manner

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] Such as figure 1 As shown, firstly, a MAC acquisition device is installed in the city, which is similar to a wireless router and transmits WiFi signals to the outside;
[0038] Second, the device can record the MAC of the smartphone that scans it, and send the scanned MAC to the background analysis system in real time.
[0039] Third, after receiving the collected MAC, store the data. On a daily basis, every time a MAC is collected, it is first judged whether the MAC has been collected by the collection device that day. If it has been collected, it will be discarded directly. If not, it is equivalent to collecting a person. to store.
[0040] Fourth, take t days as a unit (t is an integer, the minimum is 1), after deduplicating all MACs collected within t days, the total amount of MACs n is obtained, and n is divided by t and then divided by m...

The invention discloses a system and method for monitoring an urban population density, distribution and trend. The method comprises the following steps: arranging an MAC collecting device, transmitting a WiFi (Wireless Fidelity) signal to the external, recording an intelligent terminal which scans the MAC collecting device, and recording scanned MAC information; storing the collected MAC, taking set time as a unit of measurement, judging whether each collected MAC is collected within the set time, and performing duplicate removal treatment; and through collected MAC total amount and collecting time, calculating the urban population density, and calculating a regional population density to obtain a population distribution by dividing urban regions. The equipment of the invention is small in size and simple in installation, extra wiring construction is not needed, and collected MAC is transmitted internally, the bandwidth requirement is low, and full-automatic measurement can be performed for a long time and in real time.
Description
technical field [0001] The invention relates to a system and method for monitoring urban crowd density, distribution and trend. Background technique [0002] With the development of industry, the proportion of urban population in the national population continues to rise, and the urban population is increasing. How to accurately measure the density, distribution and development trend of urban population has become an urgent need for the competent authorities. [0003] The traditional calculation of urban population density can only rely on the data of permanent population and floating population held by the public security department. However, with the acceleration of urban development, the urban floating population is increasing year by year, and the frequency of floating population is also increasing. Unless necessary, these floating people generally do not take the initiative to register with the public security department and apply for a residence permit. Therefore, the...
