Abstract

The utility model provides a lattice type pressure sensing device which comprises an elastic washer, a pressure transferring structure matrix, a pressure sensor matrix and a metal back plate, wherein the elastic washer, the pressure transferring structure matrix, the pressure sensor matrix and the metal back plate are orderly stacked into a whole. Each pressure transferring structure of the pressure transferring structure matrix and each sensor of the pressure sensor matrix are up and down correspondingly arranged. Due to the adoption of the technical proposals that the pressure transferring structure matrix and the pressure sensor matrix are arranged, and pressure transferring structures of the pressure transferring structure matrix and sensors of the pressure sensor matrix are up and down correspondingly arranged, when the utility model is arranged on a stair of a bus, mobile information change of passengers who get on and off acted on the lattice type pressure sensing device can be effectively apperceived. Thus accurate lattice datum can be provided for passenger flow statistical treatment and analysis parts.

Description

The dot matrix pressure sensor device

Technical field

The utility model relates to a kind of sensing device, particularly a kind of dot matrix pressure sensor device that is used to add up bus passenger flow volume.

Background technology

In bus and supermarket, often there is a large amount of personnel's turnover in place such as exhibition, for adapting to the needs of modern management, the personnel that pass in and out above-mentioned place are added up being very important, especially on bus, based on the national conditions of China, the personnel that get on or off the bus are many, sometimes even very crowded, and same car door can have the passenger who gets on or off the bus simultaneously, the statistics difficulty especially of getting up, but, strict more demand has been proposed passenger flow statistics along with the enforcement of ITS (intelligent transportation system).This just presses for that a kind of energy is unartificial, high-accuracy, the passenger flow statistics device that is fit to the bus environment occur.Be applied to add up the device of the volume of the flow of passengers on the bus at present, that the technology of employing has is infrared, ultrasound wave, electromagnetic induction and extreme infrared or the like.Adopt the ubiquitous shortcoming of device of these technology to be, often can only add up single, unidirectional simple scenario, can't or being difficult to subsequent processing device provides all directions and all personnel's mobile message to change.Along with the employing of novel bus, the preceding mode that goes up under the back will gradually reduce, and this has higher requirement to passenger flow statistics.

Summary of the invention

The purpose of this utility model is to provide a kind of dot matrix pressure sensor device that information can be provided for the accurate statistics number of getting on or off the bus.

To achieve these goals, the utility model has adopted following technical scheme: a kind of dot matrix pressure sensor device, comprise elastic insert, pressure transferring structure matrix, pressure transducer matrix and metal backing, elastic insert, pressure transferring structure matrix, pressure transducer matrix and metal backing sequential layer build up integral body, and each the pressure transferring structure in the pressure transferring structure matrix and each sensor in the pressure transducer matrix are corresponding up and down to be provided with.

Described pressure transferring structure matrix is for triggering structure matrix, triggers respectively to trigger corresponding up and down setting of each sensor in structure and the pressure transducer matrix in the structure matrix.

Described pressure transferring structure matrix is the spherical protuberances structure matrix that sticks under the elastic insert, and each the spherical protuberances structure in this spherical protuberances structure matrix and each sensor in the pressure transducer matrix are corresponding up and down to be provided with.

Dot matrix pressure sensor device of the present utility model owing to adopted is provided with pressure transferring structure matrix and pressure transducer matrix and with pressure transferring structure in the pressure transferring structure matrix and the corresponding up and down technical scheme that is provided with of the sensor in the pressure transducer matrix.It is installed on the ladder of public transit vehicle, and effectively passenger's mobile message up and down of acting on the device of perception changes, for passenger flow statistics is handled and analysis part provides dot array data accurately.
