Abstract
The utility model discloses an acceleration sensor which comprises the components of: a circuit board assembly, a base assembly, a box body and a socket. The circuit board assembly is arranged above the base assembly. The box body is arranged above the circuit board assembly. The box body, the circuit board assembly and the base assembly are connected through screws. The socket is arranged at the right side of the box body and is connected with the box body through screws and is connected with the circuit board assembly through a circuit. The acceleration sensor is matched with automotive detecting and analyzing system of a 25T type carriage and baggage-and-article carriage. The acceleration sensor can be applied for equipment of high speed rail, bullet train, subway, light rail, common train, etc. The acceleration sensor is used for testing vibration indexes on the train body and has advantages of: small volume, high measurement accuracy, and stable and reliable performance.
Description
Technical field
The utility model relates to a kind of sensor design, and a kind of acceleration transducer is provided especially.
Background technology

Utility model content
The purpose of this utility model is to provide a kind of acceleration transducer, can effectively address the above problem.
The technical solution of the utility model is: a kind of acceleration transducer, comprise: circuit board module, base assembly, box body and socket, circuit board module is located at base assembly top, and box body is located at circuit board module top, and box body, circuit board module, base assembly are connected by screw; Socket is located at box body right side, is connected by screw, and is connected by circuit with circuit board module with box body.
Preferably, between described screw and base assembly, be provided with insulating mat, make signal ground and casing and separate.
Preferably, described circuit board module comprises Voltage stabilizing module, filtration module, micro-meter and double operational of adding; Voltage stabilizing module is connected by circuit with filtration module, filtration module respectively with micro-add meter and double operational by circuit, be connected, micro-add count be connected by circuit with double operational.
Preferably, described micro-meter that adds adopts KXM52-1048 model.
Input power is after Voltage stabilizing module voltage stabilizing and filtration module filtering, give micro-add meter and double operational power supply, micro-adding after meter senses accekeration, is led to superpotential formal output to double operational, and voltage signal is finally exported to outside terminal by socket after cushioning by double operational.
Acceleration transducer described in the utility model is the supporting product of vehicle-mounted detection diagnostic system for 25T type car and row postal car, also can be applicable in the equipment such as high ferro, motor-car, subway, light rail and ordinary train, be used for testing the vibration index (value is V/g) of car body, by the micro-meter that adds of sensitive element, sense the acceleration of train body, final output voltage signal reacts this accekeration.By the monitoring to car body acceleration output, the characteristic of the time history of computing system can be assessed train body system vibration situation simultaneously.Product adopts box structure, is convenient to install exchange and maintenance.Can be under-40 ℃～70 ℃ conditions steady operation.Volume is little, measuring accuracy is high, stable and reliable for performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Acceleration transducer described in the present embodiment, as shown in Figure 1, comprising: circuit board module 1, base assembly 2, box body 3 and socket 4; Box body 3, circuit board module 1 and base assembly 2 connect together by 4 screws and insulating mat, and recycle silicon rubber adhesive carries out embedding processing; Socket 4 and box body 3 are threaded connection fixing, and are connected by circuit with circuit board module 1.Wherein: in order to make signal ground and casing, separate, box body 3 needs insulation processing with base assembly 2, therefore need to screw and base assembly 2 be kept apart with insulating mat when being screwed box body 3 and base assembly 2.
Described circuit board module 1 comprises Voltage stabilizing module, filtration module, micro-meter and double operational of adding; Voltage stabilizing module is connected by circuit with filtration module, filtration module respectively with micro-add meter and double operational by circuit, be connected, micro-add count be connected by circuit with double operational.
Described micro-meter that adds adopts KXM52-1048 model.
After energising, input power is after Voltage stabilizing module voltage stabilizing and filtration module filtering, give micro-add meter and double operational power supply, micro-adding after meter senses accekeration, is led to superpotential formal output to double operational, and voltage signal is finally exported to outside terminal by socket after cushioning by double operational.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
