Circuit processed has its corresponding electrical code, and corresponding innovative point is not present, only belong to the known of those skilled in the art
Common sense.
The networking of electric operator: connecting router on mobile terminals, opens the distribution software on mobile terminal, defeated
The SSID and PASSWORD for entering router pin the distribution button on electric operator, open the power supply of electric operator,
After waiting wifi module LED light quick flashing, the distribution button on electric operator is unclamped, is clicked on mobile terminals " really
Recognize " button, start distribution.Until showing " configuration successful " on mobile terminal, distribution is completed.
SSID, PASSWORD, gateway, IP address and subnet mask are stored on electric operator intrinsic safety wiring board
In EEPROM.
When specifically used, the successful electric operator of distribution can be fixed on coal mine down-hole tunnel wall or be hung
It hangs on fully-mechanized mining working bracket or in other construction environments, 127V power supply is accessed into explosion-proof chamber by communicating joint 6 with cable
In body 7, by the ESP8266 chip 18 built in electric operator, electric operator can automatically with neighbouring intelligent ring
Border parameter sensors are communicated, automatic matching networking, reduce the difficulty of especially coal mine underground construction wiring.
It is passed when electric operator is received by 18 radio-frequency antenna of ESP8266 chip from matched intelligent environment parameter
The detection data of sensor will be calculated by the program being previously written in ESP8266 chip 18, to determine that the detection data is
No is more than programmed values, which can be modified by authorized site operation personnel, setting value setting
Purpose be to ensure that the variation of environmental parameter will not generate harm (such as PM2.5 or dust concentration physiologically to producers
Cross the health risk that conference causes producers) or dangerous (such as the excessively high easy explosion of methane concentration) is generated to production environment,
There is corresponding regulation in the setting value Specific construction place, if detection data (such as PM2.5 concentration value, methane concentration value) is super
Programmed values are crossed, micromotor 16 will start, and drive train of reduction gears 15 to rotate, the rotation of train of reduction gears 15 passes through transmission
Axis 12 is transmitted on valve body 14, and valve body 14 is opened, and water (or gas) goes into circulation through the lumen passageway of valve body 14.
When the wireless monitor data from matched intelligent environment parameter sensors have been restored through electric operator judgement
Normally, after the preset delay time of 18 plug-in of ESP8266 chip, micromotor 16 will back rotate, and drive and slow down
Gear set 15 rotates backward, and the rotation of train of reduction gears 15 is transmitted on valve body 14 by transmission shaft 12, and valve body 14 is closed, water
The access of (or gas) is truncated, and stops circulation.
Even if network path is since other reasons can not be connected to, electric operator is also able to maintain its self-consistency, its from
In the local area network of group, by the program that ESP8266 chip 18 is previously written, to the data of intelligent environment parameter sensors detection into
Row edge calculations, are worked independently with this.
And important is the application can use the WIFI communication of the ESP8266 chip 18 built in electric operator
Function is remotely monitored by remote server or mobile terminal, is controlled.The working condition of electric operator can pass through
Remote server and Cloud Server are inquired, and authorized personnel can pass through server monitoring program or mobile terminal
Monitoring programme manually intervenes the working condition of electric operator, long-range opening/closing electric operator.
When remote server need to manually adjust the switch state of the electric operator of a certain number, instruction will pass through
RS485 turns ether network switch, RS485 bus is passed to downhole wireless router, and passes through WIFI by downhole wireless router
Signal is sent to the electric operator of specified number, which first can carry out logic judgment to the instruction, such as should
The PRI conflict for the intelligent environment sensor signal that instruction is currently received with electric operator then ignores the instruction (ratio
Such as: someone's vehicle passes through in watering range, and electric operator can be ignored automatically holds instruction, drenches vehicle to avoid leaching people；Dust or first
When alkane concentration severe persistent is exceeded, electric operator can ignore pass instruction automatically, in order to avoid cause work safety accident)；Otherwise,
Execute the instruction.
Above-mentioned specific embodiment cannot function as the limitation to the application protection scope, for the technology people of the art
For member, any alternate modification or transformation made to the application embodiment are all fallen in the protection scope of the application.
Place is not described in detail by the application, is the well-known technique of those skilled in the art of the present technique.
