The control system of centrifugal fan includes remote monitoring and command, on-site monitoring and control, human intervention, data acquisition and detection, etc. Hidili fan will give you a brief understanding of these components.
1. Remote monitoring command (high temperature fan): the remote monitoring command part is composed of computer, management software and network transmission part, which synchronously displays the on-site working conditions through the computer network. Remote monitoring has an open interface, which can expand functions or access other systems.
2. On site monitoring and control: the on-site monitoring and control part is composed of control CPU, management control software and manual centralized operation panel. The control computer and management control software form an automatic monitoring system, which is responsible for sorting and analyzing the data transmitted from the module, making decisions according to the control strategy, and recording and storing the data. The manual centralized operation panel is parallel to the automatic monitoring system to realize the control function.
3. Data acquisition and detection: the data acquisition is completed by the intelligent module, which detects the sensor status and transmits the data to the control computer through the communication module.
4. Human intervention, automatic control by the lower computer, automatic start and stop of the centrifugal fan according to the air volume, automatic rotation of the centrifugal fan and reasonable scheduling. The manual control of the system has priority control to ensure that the normal operation of the fan can be realized under the manual control even if the system fails, and can be queried at any time Print real-time trend and historical trend in any time period. The man-machine interface displays rich content, image, intuition, simple and easy to understand. A large number of control strategies are embedded in the software, which can make different decisions according to the actual situation, and greatly improve the automation and intelligence of the system.
5. When the sensor, substation, master station, transmission cable and other equipment in the centrifugal fan system fails, the alarm will be given and the failure time and equipment will be recorded for query and printing, and the system host dual computer backup will be provided with automatic switching function. When the working host fails, the backup host is put into operation, and the high-temperature fan ensures the normal operation of the system. It has man-machine dialogue function to facilitate system generation, parameter modification and function call. It has lightning protection measures to prevent lightning from damaging the equipment.
