Accompanying drawing explanation
Fig. 1 is the utility model one example structure block diagram;
Fig. 2 is the utility model one embodiment analogue collection module circuit theory diagrams.
Embodiment
As shown in Figure 1, the utility model device adopts the system core module of ARM framework, possesses stronger arithmetic capability, and has high modularization and dirigibility.The analog input that possesses 3 16 precision in tunnel, analog input is 4-20mA, inversion frequency 200Hz, maximum transformed error is 1 ‰.9 cun of TFT liquid crystal displays that possess, pixel is 800*600.Have 512M storage space, the data of storage can be downloaded by USB interface or network.The functional block diagram of system as shown in Figure 1.
System need to have voltage transformation module that the stabilized voltage supply of 5V and 24V is provided, and realizes the control of digital quantity and the collection of analog quantity.The power supply of system is accumulator, and supply voltage is 24V.By power module, for system provides stable voltage.That power module has is overheated, overcurrent, overvoltage, under-voltage protection function.Operating temperature range is-40 ℃～+ 85 ℃.
Key-press module is realized man-machine interface, and system is provided with 8 function buttons.
As shown in Figure 2, analogue collection module has 4 road 4-20mA current collection circuits, and adopting precision circuit loop receiver is 0-5V analog voltage by 4-20mA current conversion.By modulus conversion chip, the analog signals collecting is converted to 16 position digital signals and offers control module.Precision circuit loop receiver RCV420 is 0-5V analog voltage by 4-20mA current conversion.Analog voltage output terminal connects duodiode BTA54S, and by voltage clamping, in 5V, holding circuit is not damaged by high-voltage impact.
Control module, according to the sampled value of analogue collection module, judges detected state by logical operation, result is transferred to central control unit by communication module simultaneously.Detect the state of key-press module simultaneously, by different key informations, showing the different information of screen display.By the data that detect real-time store memory module into, and provide USB and Ethernet download interface.
Wireless communication module is the wireless sensor node with Zigbee protocol, and the result by control module regularly outwards sends.
Display module is 9 cun of TFT liquid crystal displays, and pixel is 800*600, and interface module provides USB and Ethernet download interface circuit.
