Accompanying drawing explanation
Fig. 1 is circuit structure block diagram of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, electric system wireless temperature measuring device, comprises single-chip microcomputer, temperature collect module, wireless data transceiver module, the power module be connected with single-chip microcomputer, two gauge tap; Described single-chip microcomputer comprises timer, AD conversion module, microprocessor, and described microprocessor connects timer, AD conversion module simultaneously; Described temperature collect module, wireless communication module are respectively connected with microprocessor by a gauge tap; Described temperature collect module is connected with the input end of AD conversion module, and described wireless data transceiver module is connected with microprocessor.
Described temperature collect module can adopt temperature sensor or thermopair, and described gauge tap can adopt transistor switching circuit or Mos pipe on-off circuit, and described power module can adopt 3.3V or 5V direct supply.
In the present embodiment, described temperature collect module adopts the temperature sensor of LM75A model, described single-chip microcomputer to adopt MSP430F1232 single-chip microcomputer, described wireless data transceiver module to adopt the radio transmitting and receiving chip of Si4432 model, corresponding power module adopts 3.3V direct supply, the electronic switch that gauge tap adopts triode 9013 to form.
The electric system wireless temperature measuring device principle of work of the present embodiment is as follows:
Single-chip microcomputer is alternately running between sleep pattern and normal mode of operation two kinds of patterns, and the time scale of two kinds of working methods can be arranged by timer.In sleep pattern, two gauge tap disconnect, and power module is not powered to wireless data transceiver module and temperature collect module, to save system power supply.
In a sleep mode, single-chip microcomputer activates laggard people's normal mode of operation by timer interruption, judge whether by counting mode the time arriving open temp collection and data transmission in normal mode of operation, if do not arrive, then continue to enter sleep, if arrive, power on then first to other external circuit, whole system is normally worked, after once complete data acquisition is sent completely, other external circuit power supply first turned off by single-chip microcomputer, and then enter sleep pattern, timing by timer, in such a mode, entire system average operating current is approximately 10 μ A.
Under normal mode of operation, data acquisition flow complete is successively as follows:
Timer interruption activation of microprocessor, whether microprocessor judges arrives the time of open temp collection and data transmission, do not reach, enter sleep pattern, reach then Microprocessor S3C44B0X two contactors to close, power supply is powered to wireless data transceiver module and temperature collect module, then Microprocessor S3C44B0X temperature collect module carries out temperature acquisition, the temperature data gathered sends to microprocessor after being sent to and carrying out analog to digital conversion in AD conversion module, microprocessor stores data, compression, wireless data transceiver module is opened after the process such as encapsulation, data wireless is sent to host computer, complete once complete work, then wireless data transceiver module and temperature collect module is turned off, wireless data transceiver module and temperature collect module enter sleep pattern and wait for temperature acquisition work next time.
