Description

Technical Field

[0001] The present invention relates to the field of electrical control technology, and in particular to an intelligent electrical control system. Background Art

[0002] In traditional electrical control systems, the start, stop, and adjustment of electrical equipment are mainly achieved through manual operation or simple timing and fixed value control methods. This control method has many disadvantages, such as:

[0003] 1. Low control accuracy: Manual operations are susceptible to interference from human factors, making it difficult to precisely control the operating parameters of electrical equipment. This results in low equipment efficiency and significant energy waste. For example, in industrial production, even slight deviations in parameters such as motor speed and temperature can affect product quality and production efficiency.

[0004] 2. Lack of flexibility: Traditional timing and fixed-value control methods cannot adjust control strategies in a timely manner according to changes in the actual operating environment. When external conditions (such as load changes, ambient temperature fluctuations, etc.) change, the system cannot automatically adapt and still operates according to the preset program, making it impossible to ensure that electrical equipment is always in optimal operating condition.

[0005] 3. Low intelligence: Lack of real-time monitoring, fault diagnosis, and early warning capabilities for electrical equipment operation. Once a device malfunction occurs, it is often not discovered and addressed in a timely manner, leading to escalating failures, increased repair costs and downtime, and even potentially causing safety incidents.

[0006] 4. With the rapid development of information technology, higher requirements are being placed on the intelligence and automation of electrical control systems. Therefore, developing an intelligent electrical control system capable of real-time perception, intelligent decision-making, and automatic control is of great practical significance. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent electrical control system to address the existing problems of low control accuracy, lack of flexibility, and low intelligence. By integrating multiple sensors, controllers, and communication modules, this system enables real-time monitoring, intelligent control, and remote management of electrical equipment, improving its operational efficiency, reliability, and safety.

[0008] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0018] Furthermore, the data acquisition module filters, amplifies, and digitizes the collected digital signals to improve the accuracy and reliability of the data, and stores the processed data in a local memory.

[0019] Furthermore, the control algorithm adopted by the central control module is a fuzzy control algorithm or a neural network control algorithm. The fuzzy control algorithm generates appropriate control instructions through fuzzy reasoning and fuzzy decision-making based on the operating status of the electrical equipment and the uncertainty of environmental parameters. The neural network control algorithm has self-learning and self-adaptation capabilities. By learning a large amount of historical data, it automatically adjusts control parameters and optimizes control strategies.

[0020] Furthermore, the execution module is composed of at least one execution element selected from the group consisting of a relay, a contactor, a frequency converter, and a servo driver.

[0022] Furthermore, the system also supports remote firmware upgrade function, which facilitates the updating and maintenance of the system software.

[0023] Furthermore, the human-computer interaction module uses a touch screen, keyboard, and mouse as input devices, and a display screen as an output device.

[0037] Configure the parameters of the communication module, select the appropriate communication protocol and communication port, set the IP address and port number of the host computer or mobile terminal, and ensure that the system can communicate normally with external devices.

[0038] Initialize the human-computer interaction module, design a friendly operation interface, set various operation buttons and display areas to facilitate users to operate and view information.

[0039] 3. System debugging

[0040] After system installation and software configuration are complete, perform system debugging. First, calibrate the sensor modules to ensure the accuracy and reliability of collected data. Then, perform no-load debugging to check whether communication between modules is normal and whether control commands can be correctly transmitted and executed.

[0041] Gradually increase the load and conduct load debugging. Observe the operating status of the electrical equipment and the control effect of the system, and adjust and optimize the control parameters according to the actual situation until the system achieves the best control performance.

[0042] System operation and maintenance

[0043] 1. System operation

[0044] When the system is operating normally, the sensor module collects the operating parameters and environmental parameters of the electrical equipment in real time and transmits the data to the data acquisition module, which processes the data and sends it to the central control module.

[0045] The central control module analyzes and processes data based on pre-set control algorithms and strategies, generates corresponding control instructions, and sends these instructions to the execution module. The execution module operates the electrical equipment according to the control instructions, achieving intelligent control of the electrical equipment.

[0046] The human-computer interaction module allows users to view the operating status and historical data of electrical equipment in real time, perform parameter settings, and perform control operations. At the same time, the system uploads equipment operating information and alarm information to a host computer or mobile terminal through the communication module, facilitating remote monitoring and management.

[0047] 2. System maintenance

[0048] Regularly inspect and maintain the sensor module to ensure sensor sensitivity and accuracy. If a sensor is damaged or data is abnormal, replace or calibrate it promptly.

[0049] Carry out regular inspections on the data acquisition module, central control module and execution module, check the operating status and heat dissipation of the modules, clean the dust on the surface of the modules, and ensure the normal operation of the modules.
