Description
Art
The utility model relates to a kind of people's current density prior-warning device in flow monitoring field, especially people's current density early warning in the crowded region such as gallery, lookout terrace, step in scenic spot.
Background technology
Current, social economy is fast-developing, and living standards of the people improve constantly, and some public places such as scenic spot have become the main place of people's amusement, and especially during festivals or holidays, the stream of people will be more concentrated, and closeness also can rise relatively.Once generation accident, very easily there is the serious accident of the dead group's wound of group.The Ministry of Public Security has also promulgated " The Ministry of Public Security of the People's Republic of China, MOPS is about the notice of crowded place reinforcement management of fire safety " 2007 on Dec 20.
In the recent period, all parts of the country there occurs a series of serious accident, cause tremendous economic loss and casualties.This has also beaten alarm bell to us again, and the place that flow of the people is intensive also exists various potential safety hazard.In order to ensure the safety of people's lives further, economical further develops.So crowded place exercised supervision and control very urgent.
The generation of the tread event of Bund in Shanghai, allows everybody restart to pay close attention to the safety problem in the intensive places of flow of the people such as scenic spot.Article 8 also clear stipulaties in " park, Beijing scenic spot safety management specification " that go into effect for 2005: scenic spot, sight spot overstaffed (indoor reach 1 square metre of everyone, outdoor reach 0.75 square metre everyone), will initiate emergency plan immediately, evacuate visitor.
Consult at present to document patent in, monitoring method for the scenic spot stream of people is adopt install camera or install stream of people's statistic device etc. additional on doorway, scenic spot mostly, not in scenic spot or densely populated location, as people's current density prior-warning device installed by step, gallery etc.
Summary of the invention
Goal of the invention is the problem of the people's current density early warning in order to solve the crowded region such as gallery, lookout terrace, step in scenic spot.The utility model designs people's current density prior-warning device that a kind of cost is low, reliability is high.
The utility model solves the technical scheme that its technical matters adopts:
People's current density prior-warning device is made up of infrared launcher, infrared receiving device, it is characterized in that infrared launcher is connected with wireless communication module, multiple infrared emission sensor by single-chip microcomputer; Infrared receiving device single-chip microcomputer is connected with multiple infrared receiver sensor, wireless communication module, GPRS module, voice module.
Described infrared launcher comprises single-chip microcomputer, wireless communication module, multiple infrared emission sensor, employing elongate in shape designs, an infrared emission sensor is set at a certain distance, single-chip microcomputer is connected by UART interface with wireless communication module, and single-chip microcomputer is connected by general purpose I/O interface with infrared emission sensor.The infrared emission order sended over according to infrared receiving device by single-chip microcomputer, timing sends infrared signal to infrared receiving device.Shell adopts the large aluminum alloy casing of intensity to encapsulate.
Described infrared receiving device comprises single-chip microcomputer, wireless communication module, multiple infrared receiver sensor, voice module, GPRS module, employing elongate in shape designs, an infrared receiver sensor is set at a certain distance, with the infrared emission sensor one_to_one corresponding on infrared launcher, single-chip microcomputer is connected by UART interface with wireless communication module, single-chip microcomputer is connected by general purpose I/O interface with infrared receiver sensor, single-chip microcomputer is connected with voice module by SPI interface, and single-chip microcomputer is connected by UART with GPRS module.The infrared signal sended over according to infrared dispensing device by single-chip microcomputer, calculate the stream of people by time the probability that is blocked, when the probability that multiple receiving sensor is blocked within the unit interval is greater than certain numerical value, namely when people's current density reaches safe-guard line, send audio alert information, everybody current density of presenting bank is excessive, please notes safety, given the alarm to administrative authority by GPRS module simultaneously, carry out the stream of people to arrange personnel and dredge.
When flow of the people is very low, infrared receiving device sends order to infrared launcher, reduces transmission frequency.Infrared emission frequency is improved during flow of the people height.
The beneficial effects of the utility model are, can be implemented in flow of the people and easily occur intensive area monitoring people current density, and send early warning information, are of value to the personnel Quan An ensureing flow of the people close quarters.
