Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

The technical scheme that its technical problem was solved to this utility model is:

a switch machine with remote early warning function comprises an STM32 single chip microcomputer, a temperature detection module, a humidity detection module, a GPS module, a GSM module, a handheld terminal, a liquid crystal display module and a power supply module. Please refer to fig. 1, the STM32 single chip microcomputer is respectively connected with the temperature detection module, the humidity detection module and the GPS module to collect data, the liquid crystal display module is connected with the STM32 single chip microcomputer to display data, the GSM module is connected with the STM32 single chip microcomputer to send data, the GSM module and the handheld terminal are in wireless communication through the GSM network, and the power module supplies power to the temperature detection module, the humidity detection module, the GPS module, the liquid crystal display module, the GSM module and the STM32 single chip microcomputer.

The utility model discloses the data acquisition part is by the GPS module, temperature detection module and humidity detection module constitute, the sensor of each module at first reads the position, temperature and humidity, then send data through the serial ports, after the serial ports received the data instruction, convey the singlechip with data transfer, the serial ports is if not received the data instruction, then return and continue to gather the position, temperature and humidity, the singlechip is if not received data, then return the serial ports and continue to send the data of gathering, the singlechip is if received data, then judge whether the GSM module sends the early warning SMS (send the early warning SMS before the data comparison), if not send, then return and continue to gather temperature and humidity, if send the early warning SMS, then end data acquisition. Please refer to fig. 2.

The utility model discloses data transmission part passes through single chip microcomputer system initialization, liquid crystal initialization, the initialization back of GSM module, and control system reads data, and the data of the collection end that will read are in proper order relatively judge whether temperature and humidity reach the early warning value, then send information to handheld terminal through the GSM module and carry out the early warning if numerical value is unusual, then return control system and continue to read numerical value and compare if numerical value is normal. Please refer to fig. 3.

The temperature and humidity early warning value of the utility model is set according to the requirement of the normal working environment of the point switch, wherein the value of the ambient air temperature is-40 ℃ to +70 ℃, and the value of the relative humidity of the air is not more than 90% (when 25 ℃).
