Zhuhai Chenghao Electronic Air Conditioning Monitoring System is a factory air-conditioning wireless monitoring system designed by Xinli Technology for Zhuhai Chenghao Electronics Co., Ltd. It uses Xinli Technology wireless management device, wireless measurement and control device and other wireless products to form a complete wireless network. Real-time monitoring of air conditioners.
The following is an overview of the Zhuhai Chenghao Electronic Air Conditioning Monitoring System:
1. Project Background
This air-conditioning monitoring system can be used to detect the working status (start/stop) of the air-conditioning in the factory, and control the time period for the start and stop of the air-conditioning, which can realize the decentralized collection of field equipment and the centralized control of the monitoring center.
2. Project requirements
1. Real-time monitoring of 40 air conditioners is realized, and WN60 wireless measurement and control device is installed in each air conditioner;
2. Realize the monitoring and control of the start and stop states of 40 air conditioners;
3. The monitoring center is equipped with a touch screen, and the control signal is transmitted to the PLC through the switching time set by the touch screen on the main monitoring machine, and then the PLC outputs the control signal to the WN90 wireless management device to control the start/stop of the air conditioner;
4. The start/stop status of each air conditioner compressor is displayed on the touch screen;
5. Control the start/stop of each air conditioner compressor on the touch screen.
3. Scheme design
The monitoring system is a layered distributed network structure, consisting of a three-layer structure of equipment layer, wireless network transmission layer, and monitoring layer. The equipment layer is mainly the power contactor of the air conditioner compressor; the wireless network transmission layer is mainly composed of wireless measurement and control devices, wireless management The monitoring layer includes the main monitoring machine, monitoring management software, PLC, etc.
1. A single air conditioner is equipped with a WN60 wireless measurement and control device. According to customer requirements, WN60 is 2DI and 2DO. It is used to monitor the start/stop status of each compressor of the air conditioner and control the start/stop of the compressor. way to transmit to WN90 wireless management device;
2. The WN90 network port wireless management device communicates the received signal with the monitoring center host through the network port to achieve the purpose of decentralized collection and centralized monitoring of remote transmission.
The topology of the system network structure is as follows:
1. Wireless management device: manage the entire wireless network, and there is a wireless communication management device in one network;
2. Wireless routing (relay) device: plays the function of routing and relaying in the network to extend the communication distance of network nodes;
3. Wireless measurement and control device: responsible for equipment data collection and transmission.
Fourth, the upper computer monitoring effect diagram
The following is a screenshot of the wireless monitoring effect of Zhuhai Chenghao Electronic Air Conditioning Monitoring System. Xinli Technology’s wireless products collect the data of each air conditioner status into the terminal control system, and relevant personnel can adjust and control in real time according to the data.
