Device connects, and the wireless energy control units include wireless transmit handle and wireless receiver, and the wireless transmit handle will control life
Order is sent to wireless receiver by way of less radio-frequency, after the receiver receives wireless signal, wireless signal is entered
Go and decode and verify, and digital command signal is converted into into the signal of telecommunication and send the PLC to.
Further, the control system also includes being electrically connected alarm with PLC, for going out when control system
Chimes of doom is sent during existing failure.
The beneficial effects of the utility model are：Real-time detection body of heater ambient temperature difference is realized, is preset when difference exceedes
After value, system drives unlatching blowing device to provide air quantity to burner mouth automatically, solves the problems, such as that the intensity of a fire is uneven in stove, replaces artificial
Operation, drastically increases the quality of production.
Description of the drawings
Fig. 1：This utility model internal circuit configuration block diagram.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail.
As shown in figure 1, the control system of production potash fertilizer, including PLC, A/D converter, signal amplifier, multichannel
Switch, multiple temperature sensors, relay, blowing device and 24VDC power modules, the input of the plurality of temperature sensor
Body of heater surrounding of the end installed in mannheim furnace, the outfan of the plurality of temperature sensor pass sequentially through the variable connector, letter
Number amplifier, A/D converter are electrically connected with the PLC, and the PLC is by the relay practical operation
The blowing device, the blowing device for mannheim furnace burner mouth dry, the 24VDC power modules, for
Whole control system provides 24VDC power supplys, and each temperature sensor is formed independent passage by the variable connector.
Wherein said temperature sensor is preferably with thermocouple temperature sensor, measurement range：0 DEG C to 800 DEG C scope, tool
Have small volume, thermal response fast, structure order, it is easy to use the features such as.
Preferably, the blowing device is the equipment of fan, or other offer air quantity.
Preferably, the control system also includes the RS485 communication interfaces with PLC electrical connection, for by institute
The signal of communication for stating the Transistor-Transistor Logic level of PLC output is converted into the interface of RS485 standards.Can be with by RS485 communication interfaces
Set up with host computer and communicate, can realize sending that operational order, to PLC, completes corresponding action, together by host computer
When, can also the real time data that detected of direct access control system and record data by host computer.
Preferably, the control system also include wireless energy control units (not shown), the wireless energy control units with
The PLC connection, the wireless energy control units include wireless transmit handle and wireless receiver, the wireless transmit handss
