Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, a kind of data communication system of humiture collection, including digital temperature and humidity acquisition module 1, simulation temperature Spend acquisition module 2, sensor interface 3, power supply module 4, processor 5, liquid crystal display 6, input module 8, output module 9, transmission mould Block 7, digital temperature and humidity acquisition module 1, analog temperature acquisition module 2, sensor interface 3, power supply module 4, liquid crystal display 6, input Module 8, output module 9, transmission module 7 are connect with processor 5.

Digital temperature and humidity acquisition module 1 and analog temperature acquisition module 2 distinguish collecting temperature and humidity, and by the number of acquisition It is transmitted in processor 5 according to by transmission module 7 and sensor interface 3, debugging button is added by input module 8, led to It crosses output module 9 and realizes warning function.

Digital temperature and humidity acquisition module 1 can also select more advanced, such as SHT75 etc. using the sensor of SHT20 models The higher sensor of precision, meets the needs of different clients.Analog temperature acquisition module 2 will be realized reaches 0.1 ° using PT1000 Temperature acquisition, in this way when doing Calibration Report, just substantially can to avoid because the problem of temperature trip stop cause calibration to be lost It loses, while the acquisition precision of temperature can also be improved in practical applications.It is (every that sensor interface 3 mainly provides 485 interfaces A sensor is required for rewriting data acquisition command).
