Fig. 2 is the utility model system hardware structure figure.
Embodiment
The utility model is intended to develop one for gathering the wireless sense network system of refuelling station's tank pressure value, its overall system frame diagram is as Fig. 1, whole system is divided into 5 layers, between five layers, adjacent two layers can be communicated by letter each other, every layer all can only be thereon lower adjacent transmits data and signal between two-layer, can be described as 5 layer models.Refuelling station of the present utility model hydraulic data acquisition system comprises that pressure data gathers sensing module, ZigBee terminal, ZigBee telegon, and described pressure data gathers sensing module and comprises pressure transducer, stm32 F103 single-chip microcomputer and serial communication interface; The output pin of pressure transducer connects the signal input part of stm32 F103 single-chip microcomputer, the integrated analog digit converter of stm32 F103 single-chip microcomputer own, the output of pressure transducer is converted into digital signal to be processed, stm32 F103 single-chip microcomputer is connected with the function bottom board of ZigBee terminal by serial ports RS232, ZigBee telegon is connected with computing machine by serial ports RS232, between ZigBee terminal and ZigBee telegon, is connected by ZigBee Wi-Fi.
ZigBee cordless communication network is made up of two parts: terminal node and coordinator node.ZigBee terminal, ZigBee telegon that the utility model uses include ZigBee CC2530 module, ZigBee function bottom board, double-direction radio emitting antenna, serial communication interface, described ZigBee function bottom board connects respectively ZigBee CC2530 module and serial communication interface, and ZigBee CC2530 module connects double-direction radio emitting antenna.
As shown in Figure 2, terminal node comprises MPS20N0030D-S type pressure transducer, stm32 F103C8T6 single-chip microcomputer, RF radio frequency chip ZigBee CC2530 F256 and antenna, LED state pilot lamp and RS232 serial ports, and wherein pressure transducer is for gathering the force value data of oil tank; The force value that stm32 F103C8T6 single-chip microcomputer imports into from pressure transducer for rough handling, corrects with package processing to force value etc.; RS232 sends to ZigBee terminal node CC2530 for the data that rough handling is completed by RS232.CC2530 is by force value for ZigBee terminal, and the network information etc. further package send on ZigBee cordless communication network by antenna, so that ZigBee telegon receives; LED, GPIO etc. show for state.
