Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Visible by Fig. 1: the utility model comprises: waterproof case 12; Settle diffuse si core body 1 at described waterproof case 12 inner bottom parts; In described waterproof case 12, also comprise: rapid-acting coupling 2, back-up ring 3, circlip for hole 4, transmission circuit plate 5, master control (MCU) circuit board 6, GPRS wireless module 7, GPS module 8 and electric battery 11; Described diffuse si core body 1 is installed in the rapid-acting coupling 2, with the fixing diffuse si core body 1 of back-up ring 3; Described transmission circuit plate 5 is placed on the circlip for hole 4, and the output of the bridge of diffuse si core body 1 is connected to transmission circuit plate 5 input ends, and transmission circuit plate 5 data output interfaces link to each other with master control (MCU) circuit board 6; GPRS on described master control (MCU) circuit board, GPS interface link to each other respectively with GPS module 8 with GPRS module 7; Electric battery 11 power supply that links to each other with main control board 6; Give GPRS module 7, GPS module 8, transmission circuit plate 5 and 1 power supply of diffuse si core body through main control board; On described waterproof case 12 tops, settle gps antenna 9 and GPRS antenna 10 respectively; The described diffuse si core body 1 stainless steel diaphragms 101 outer with being placed in waterproof case 12 link to each other.

The diffuse si core body is encapsulated in the 316L stainless steel casing for the diffused-silicon pressure sensitive chip in the utility model; Impressed pressure is delivered on the responsive silicon chip through the silicone oil of stainless steel diaphragm, inner sealing; Responsive silicon chip does not directly contact measured medium; Form tonometric isolation structure, so this product can be applied to various occasions, comprise abominable Korrosionsmedium environment.The transmission circuit plate is to be used for diffuse si core body circuit to amplify, temperature compensation, linear gauging, and the output of the temperature and pressure digital signal after quantizing (I2C agreement).Master control (MCU) circuit board is responsible for reading the temperature and pressure digital signal of transmission circuit plate output; Control GPS module also reads the data that it sends; And various data (like temperature, pressure, longitude, latitude, time or the like) are uploaded to data server with the tcp/ip communication agreement, and each modular power source is carried out the low-power consumption management through the GPRS module.The GPRS module is used for the exchanges data between master control (MCU) circuit board and the data server, and the GPS module is used for the longitude and the latitude data in read sensor geographic position, and battery is that total system provides electric energy.

The principle of work of the utility model low-power consumption battery-powered wireless (GPRS) teletransmission pressure transducer is following: the MCU of master control (MCU) circuit board will get into normal mode of operation from sleep pattern when arriving setting-up time, the task that executive routine is provided with.At first; Wake the pressure survey chip of transmission circuit plate up through instruction; After the pressure survey chip of transmission circuit plate wakes up; The differential signal that just the diffuse si core body is produced amplifies, and gathers and conversion the trip temperature of going forward side by side compensation and linear gauging; Temperature and pressure digital signal after will quantizing is at last exported with the I2C agreement; The MCU of master control (MCU) circuit board stores in the buffer memory after reading the temperature and pressure signal that the transmission circuit plate sees off through the I2C agreement, and is that the MCU of master control (MCU) circuit board then starts the GPS module and gather current geographical location information (longitude and latitude), and the MCU of master control then (MCU) circuit board integrates these data (temperature, pressure, longitude, latitude, time or the like).Control the GPRS wireless network of GPRS module through China Mobile then and send to the data server on the internet with ICP/IP protocol.After receiving the data verification successful information that data server passes back.The MCU of master control (MCU) circuit board gets into sleep pattern, and cuts off GPRS module and GPS modular power source, makes total system get into low power consumpting state.When setting-up time next time then; MCU is waken up once more; So circulation, just pressure and temp and other data upload with each time point arrives data server, and the MCU of the circuit board of master control (MCU) simultaneously can be according to the condition of setting (reporting to the police like the pressure bound); Detecting when satisfying these conditions, just in time initiatively relevant information is being uploaded to data server.The monitoring software system that on data server, moves can monitor all equipment operation conditions in real time and write down all data of uploading, and can generate data sheet and carry out data analysis and inquiry.Simultaneously can monitor and inquire about relevant device and data whenever and wherever possible according to authority setting through the internet.The very big so timely control that has made things convenient for operating personnel and managerial personnel to status of equipment and information.
