Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1, a kind of device for automatic identification Temperature Humidity Sensor, including Temperature and Humidity unit line plate
7, the left side top of the Temperature and Humidity unit line plate 7 is power interface 1, and the lower section of the power interface 1 is that communication connects
The right side of mouth 2, the communication interface 2 is equipped with CPU detection units 3, and the right side of the CPU detection units 3 is equipped with AD conversion unit
4, the right side of the AD conversion unit 4 is equipped with sensor switch unit 5, and the right side of the sensor switch unit 5 is equipped with sensing
Device interface 6.The Temperature and Humidity unit line plate 7 is oblong-shaped.
As shown in Fig. 2, the control mouth line control for measuring CPU8, which exports high/low level, controls 9 public termination of analog switch
Enter opened point/normally closed point (NO/NC).9 internal common terminal of analog switch is connected into its opened point when Control is high level,
Realize that CPU8 is connect with the SDA/SCLK mouth lines of digital analog converter 10,9 opened point of analog switch accesses digital analog converter 10 and samples
End input terminal is by being linked into connection of the realization of sensor wire terminal 12 to RTD sensor.Otherwise, control is low level
When, analog switch 9 is all connected with normally closed point, is realized that SDA/SCLK is connected on sensor wire terminal 12, is realized and passed to STH20
The connection of sensor data/address bus.CPU8 is measured by controlling control mouth lines, logarithm mode converter 10 and external data sensor
Data are directly read, and are obtained data and are analyzed, the classification of discriminating sensor, and are recorded.When reading again sensing data
Categories of sensors information is directly invoked, operation and control mouth line control calls corresponding function to carry out digital independent.Reach certainly
The purpose of identification.It finds that data are overflowed in reading process, sensor recognizer will be restarted.After categories of sensors to be determined
Data of the Temperature and Humidity module is read, sends FTU units to by correspondence.
Technical solution：Digital temperature sensor is accessed based on (CPU MSP430F5438A) control analog switch SGM3005
The chip AD7793 of SHT20 or thermal resistance (PT100) AD conversion read the value of sensor, realize to Temperature and Humidity Control.CPU exists
The type of identification sensor first when putting into operation.If CPU does not detect sensor, it will know every 30 seconds startup sensors
Other program again identifies that；When CPU detects sensor, sensor type Sensor can be demarcated, and be stored in corresponding
Storage unit, directly invoke in the process of running type information read detection parameters, into Temperature and Humidity Control program.If again
Sensor abnormality occurs, Sensor values will be reset again, and CPU will be again introduced into sensor type detection program.
The device that the utility model uses includes analog switch；SGM3005-binary channels low on-resistance (SPDT) device；
SHT20-number humiture collection chip, interface mode spi bus；24 high-precision AD chips of AD7793-, interface mode
Iic bus.
The utility model sensor interface uses 4 mouth line connectors.CPU voluntarily identifies the sensor of access, realizes sensing
Device plug and play need not be configured separately.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above, one's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
