Background technology
In recent years, along with air pollution is further serious, there is comparatively serious dust pollution in China's most area, the detection to dust pollution existed in prior art and transmission system, if application number is the application for a patent for invention of 201410067312.4, disclose a kind of PM2.5 monitoring system and using method thereof, specifically disclose the monitoring means of PM2.5, but it still exists the requirement that the comparatively fixing and quantity of data collection point of dust concentration monitoring can not meet large data acquisition, data publication does not have real-time.
Utility model content
In order to solve the problem, the utility model provides a kind of dust based on vehicle-mounted OBD interface and detects and data transmission system, dust detecting portion by system is connected with vehicle-mounted OBD interface, real-time Transmission, storage and issue are carried out to data, thus achieves the object of large quantity, dynamically dust concentration detection on a large scale.
The utility model adopts following technical scheme to be: a kind of dust based on vehicle-mounted OBD interface detects and data transmission system, comprising:
Dust sensor, gathers dust concentration signal;
GPS module, obtains the geographical location information being provided with the vehicle of dust sensor;
Vehicle-mounted OBD interface, is connected with CAN acquisition module and K bus acquisition module, and dust sensor is connected for plugging with vehicle-mounted OBD interface;
Main control chip, it has CAN interface, and CAN acquisition module is connected with the CAN interface of main control chip, and K bus acquisition module is connected with the serial ports of main control chip, and GPS module is connected with main control chip;
Gsm module, it is connected by serial ports with main control chip, passes through wireless network transmissions in order to the geographical location information that exported by main control chip and dust concentration information; And
Cloud server, in order to receive and to store geographical location information and the dust concentration information of main control chip output.
Further, described main control chip is STM32 single-chip microcomputer, and described dust sensor is DSM501 dust sensor.
Further, the geographical location information that stored of described cloud server and dust concentration information export display terminal to.
Software program involved by the utility model comprises dust sensor gathers the program of dust concentration signal, GPS module obtains positional information program, server receives, store, the program of transmission data and display routine, and it is the usual software program to data acquisition, conversion and process to those skilled in the art.Serial communication involved by the utility model, bus communication protocol are also known communication standard.
Beneficial effect: the utility model utilizes vehicle-mounted OBD interface to be connected with dust sensor, the measuring ability of dust sensor to dust is fixed on vehicle, and utilize the positioning function of GPS module to obtain positional information, achieve the detection of dynamic to zones of different dust in vehicular motion, native system is applied, along with the quantity of vehicle of installing native system is constantly accumulated, also can to realize on a large scale, the detection of dynamic object of the environment dust of large quantity.
This equipment use OBD interface has following benefit: as used external power source, there will be the frequent trouble changing battery, powers avoid this defect with OBD interface; Adopt OBD to power, save space; OBD interface is international standard interface, powers with this interface, and equipment can be made to have more versatility.
