Sub- IN1 is disconnected to control after relay module terminal NO1 and COM1 is connected 1 second, which passes through quick plug end
Sub- B1, B2, quick socket terminal C1, C2 are conveyed to controlled circuit, enable the coil of cooling blower relay KM1 be powered 1 second, often
It opens contact to be also closed 1 second, control loop composition is self-locking, and the coil of cooling blower relay KM1 continues to remain powered on state；
Cooling blower stop button is clicked on the webpage of host computer, website backstage and the program of microcomputer raspberry pie operation are handed over
Mutually, program is conveyed to the relay module terminal of I/O component to 23 output order of microcomputer raspberry pie I/O port terminal, the instruction
IN2 is connected to control after relay module terminal NC2 and COM2 is disconnected 1 second, which passes through quick plug terminal
B3, B4, quick socket terminal C3, C4 are conveyed to controlled circuit, enable the coil blackout of cooling blower relay KM1 1 second, normally opened
Contact also disconnects 1 second, and the self-locking of control loop is revoked, and the coil of cooling blower relay KM1 continues to remain powered off state；
The line of the coil of cooling pump relay KM2, the coil for freezing pump relay KM3, compressor relay KM4 in controlled circuit
The control of circle is similar with the control of coil of cooling blower relay KM1；
The first normally opened contact on-off information of cooling blower relay KM1 is conveyed to quick socket terminal in controlled circuit
C17, C18, then it is conveyed to through quick plug terminal B17, B18 terminal A4, A5 of the connecting terminal of I/O component, it is finally conveyed to micro-
Type computer raspberry pie I/O port terminal 11, GND, microcomputer raspberry pie operation program read the information after, by with behind website
Platform interaction, shows the information on webpage；
The first normally opened contact letter of cooling pump relay KM2, freezing pump relay KM3, compressor relay KM4 in controlled circuit
Breath acquisition is similar with the first normally opened contact information collection of cooling blower relay KM1；
Temperature sensor detects the temperature of refrigeration equipment, and temperature value is reached microcomputer tree by the terminal A2 of connecting terminal
The certain kind of berries sends I/O port terminal 4, after the sequential operation of microcomputer raspberry pie operation, then by interacting with website backstage, in webpage
On show the temperature value.
