Embodiment 1
[0020] Such as figure 1 As shown, the taxi passenger flow detection system based on the pressure sensor of the present embodiment includes a background server, a microprocessor, a power supply module, a pressure sensor, a positioning module and a display module;
[0021] The power module, microprocessor, pressure sensor and positioning module are all installed on the taxi. The power module converts the 12V storage battery of the taxi into a 5V power supply for the microprocessor and the pressure sensor. The power module of this embodiment uses a three-terminal Regulated integrated power supply chip LM7805 and two filter capacitors, the specific connection is as follows Figure 4 shown;
[0022] The pressure sensor is installed on each passenger seat of the taxi, and the pressure sensor is a piezoresistive sensor; the pressure sensor includes an auxiliary resistor and a pressure sensitive element, and the resistance output characteristics of the pressure sensitive element are ...

The invention discloses a pressure sensor-based taxi passenger flow detection system. The system comprises a background server, a microprocessor, a power supply module, a pressure sensor and a positioning module. The power supply module supplies power to the microprocessor, the pressure sensor and the positioning module. The pressure sensor is installed on a seat of a taxi. The microprocessor is electrically connected with the pressure sensor. The microprocessor reads the current position data of the taxi in the positioning module after the pressure sensor is triggered. The microprocessor stores the position data and the current time and transmits the position data and the current time to the background server. The detection system is used for detecting the passenger getting-on and getting-off information of all taxies in a region where the taxis are located through the pressure sensor. Meanwhile, the requirements of different traffic cells on taxies can be counted in real time. The system is accurate and reliable in data source and timely in data updating. By means of the system, the taxi demand of all traffic cells in a region where a taxi operation company is located is conveniently mastered by the taxi operation company. The reasonable taxi scheduling is made by the taxi operation company.
Description
technical field [0001] The invention relates to the field of vehicle operation management, in particular to a pressure sensor-based taxi passenger flow detection system. Background technique [0002] For a city or region, due to the difference in population density and functional positioning, the traffic districts in the city or region have different vehicle demands. If a taxi operating company needs to improve the operating efficiency of taxis, it needs to make adaptive deployment of all taxis in the company according to the specific needs of each traffic area. Allocating an appropriate number of taxis to each traffic area can satisfy Reducing the waiting time of passengers can also reduce the idle time of taxis and increase the revenue of taxi companies. In the prior art, taxi companies mainly obtain data about the demand for taxis in various traffic districts through market research and operating experience. This method of data acquisition has two defects: (1) the accura...
