The PLC controller 12 is connected to the corresponding rectification device 11 through a communication line, and is responsible for collecting device status data and executing control commands. The host computer 13 is connected in communication with a plurality of the PLC controllers 12, and specifically, the remote centralized control electrolytic metal rectification system 10 includes one or more host computers 13, and the host computer 13 is connected to all the PLC controllers 12 through a network. The host computer 13 is responsible for centralized management and monitoring of all rectifier devices 11, providing a user interface to realize control and monitoring of the entire remote centralized electrolytic metal rectifier system 10. By setting up a remote centralized electrolytic metal rectifier system 10, centralized monitoring and management of rectifier devices 11 dispersed in different locations can be realized, which significantly reduces the complexity of coordination between devices, improves the system's rapid response and processing capabilities to faults, and thus improves the efficiency and reliability of the entire electrolytic metal production process.

[0037] Please continue reading Figure 1 In some specific implementations, the plurality of rectifier devices 11 are composed of a plurality of type-1 rectifier stations 111 and a plurality of type-2 rectifier stations 112, and the two types of rectifier stations together constitute the hardware foundation of the entire remote centralized control electrolytic metal rectifier system 10; the plurality of type-1 rectifier stations 111 and the plurality of type-2 rectifier stations 112 are all arranged in the same network segment, which facilitates network management and ensures the stability and efficiency of data communication.

[0038] Among them, multiple Type II rectifier stations 112 are all provided with a trigger controller 116, and the trigger controller 116 is communicatively connected with the PLC controller 12; specifically, the significant feature of the Type II rectifier station 112 that distinguishes it from the Type I rectifier station 111 is that the Type II rectifier station 112 is equipped with a trigger controller 116, and the trigger controller 116 is responsible for real-time monitoring of the rectification process and dynamically adjusting the rectification parameters as needed to optimize the rectification effect; each trigger controller 116 is communicatively connected with the corresponding PLC controller 12 to realize data exchange and transmission of control instructions, thereby ensuring that the Type II rectifier station 112 can be effectively controlled and monitored by the host computer 13 system.

[0039] By setting the trigger controller 116, the rectification efficiency is further improved, making the rectification process more accurate and efficient, which helps to reduce energy consumption and improve the quality and output of metal electrolysis. At the same time, the setting of the type 1 rectification station 111 and the type 2 rectification station 112 in the same network segment simplifies network management, so that the host computer 13 can control both the type 2 rectification station 112 and the type 1 rectification station 111, thereby improving the reliability of data communication and the convenience of control.

[0040] Please continue reading Figure 1 In some specific implementations, the plurality of type II rectifier stations 112 are all provided with a rectifier transformer 113 and a thyristor rectifier 114; the rectifier transformer 113 is mainly used to convert the input AC voltage into a voltage level suitable for the electrolysis process, and the thyristor rectifier 114 is responsible for converting the transformed AC power into DC power for use in the electrolysis process. Different from the diode rectifier 115, the thyristor rectifier 114 is controllable, and the output DC voltage can be adjusted by changing the trigger angle of the thyristor, and the thyristor rectifier 114 has high controllability. The rectifier transformer 113 is electrically connected to the thyristor rectifier 114, so that data exchange and power transmission are carried out between the rectifier transformer 113 and the thyristor rectifier 114, ensuring the coordination of the rectification process and optimizing the rectification efficiency; the thyristor rectifier 114 is communicatively connected to the trigger controller 116, so that the trigger controller 116 can dynamically adjust the trigger angle of the thyristor rectifier 114 according to the parameter changes monitored in real time, so as to control the accuracy and stability of the rectification process. The rectifier transformer 113, the thyristor rectifier 114 and the trigger controller 116 are arranged in communication connection, which not only makes the rectification process more efficient and stable, but also helps to reduce energy consumption and improve production efficiency. At the same time, through real-time monitoring and dynamic adjustment, the remote centralized control electrolytic metal rectification system 10 can respond more quickly to any abnormal situation that may occur in the electrolysis process, ensuring the continuity and safety of production.

[0041] Please continue reading Figure 1In some specific embodiments, a plurality of the type-I rectifier stations 111 are provided with a rectifier transformer 113 and a diode rectifier 115; the rectifier transformer 113 is responsible for converting the AC voltage into a voltage level suitable for the electrolysis process, while the diode rectifier 115 converts the transformed AC into DC. Different from the thyristor rectifier 114, the diode rectifier 115 has a simple structure, low cost, and convenient maintenance. It can complement the thyristor rectifier 114 and reduce the cost of the remote centralized control electrolytic metal rectification system 10. The rectifier transformer 113 is electrically connected to the diode rectifier 115, so that the rectifier transformer 113 and the diode rectifier 115 can exchange information and power transmission to coordinate the rectification process and ensure conversion efficiency and stability; the diode rectifier 115 is communicatively connected to the corresponding PLC controller 12, so that the PLC controller 12 can receive the operating data of the diode rectifier 115 and adjust the rectification process according to these data to optimize performance and respond to faults.

Specifically, the first switch 16 has the advantages of sufficient number of ports, high stability and data processing capability. Through the first switch 16, each PLC controller 12 can establish a stable communication connection with the host computer 13, so that data and control instructions can flow between the host computer 13 and each PLC controller 12.

[0044] Please continue reading Figure 1 In some specific implementations, the host computer 13 and the touch screen are both provided with manual / automatic conversion buttons; specifically, in the "manual" state, the DC load can only be controlled by starting the up and down relays through the up and down buttons of the host computer 13 or the touch screen; in the "automatic" state, according to the DC current required by the electrolytic cell, the operating current and the adjustment current range are set on the host computer 13 or the touch screen, and the feedback is fed back to the PLC controller 12 for calculation, the real-time operating value is compared with the set value, and then a delay judgment is made for program control. The PLC controller 12 can automatically start the up or down relay according to the upper and lower limit control angle range set on the host computer 13 or the touch screen, and automatically perform on-load voltage regulation on the transformer to make the DC current output value of the unit reach the required value of the electrolytic cell, while preventing false touches, executing when the logic is correct, and terminating when an error occurs, and manual confirmation and reset are required to ensure the safety of the equipment. By implementing the manual / automatic conversion function in the remote centralized control electrolytic metal rectification system 10, it is possible to better adapt to different production and maintenance requirements, and improve the operational flexibility and production efficiency of the remote centralized control electrolytic metal rectification system 10.

[0045] Please continue reading Figure 1In some specific embodiments, several of the rectifier devices 11 are provided with sensors, and the sensors are connected to the corresponding PLC controller 12 in communication; specifically, multiple sensors collect and connect analog input signals, digital input signals, and digital output signals to the PLC controller 12 on site through a five-core cable. The multiple sensors can be temperature sensors, pressure sensors, flow sensors, displacement sensors, photoelectric sensors, and Hall effect sensors. After receiving the sensor data, the PLC controller 12 processes and analyzes the data according to the preset control logic. If any abnormal situation or indicators that deviate from the normal working range are detected, the PLC controller 12 will immediately take corresponding control measures, such as adjusting the working parameters of the rectifier device 11, issuing an alarm, or shutting down when necessary. By installing sensors on the rectifier device 11 and establishing a communication connection with the PLC controller 12, the remote centralized control electrolytic metal rectifier system 10 can realize accurate monitoring and intelligent control of the rectification process, improve the safety and reliability of the system, optimize the production process, and reduce energy consumption.

[0046] Please continue reading Figure 1 In some specific embodiments, the remote centralized control electrolytic metal rectification system 10 further includes a monitoring mechanism 15, which includes a plurality of cameras 151, a second switch 152 and a monitoring screen 153; one or more cameras 151 are correspondingly arranged for each rectification device 11 to ensure that the operation status of the rectification device 11 can be monitored in all directions. The plurality of cameras 151 are connected to the monitoring screen 153 through the second switch 152; the communication connection between the plurality of cameras 151 and the monitoring screen 153 is realized through the second switch 152. The plurality of cameras 151 are arranged in a one-to-one correspondence with the plurality of rectification devices 11, and the cameras 151 are used to monitor the rectification devices 11 and display the video images captured by each camera 151 in real time. The operator can observe the operation status of the rectification device 11 in real time through the monitoring screen 153, and promptly discover and deal with possible problems.

[0047] Please continue reading Figure 1 In some specific implementations, the host computer 13 is provided with a fault analysis module, and the sensor and the second switch 152 are both in communication connection with the fault analysis module. Specifically, the fault analysis module can receive real-time data from the sensor of the rectifier device 11 and the monitoring video data transmitted through the second switch 152. By analyzing these data, the module can identify abnormal conditions or faults that may occur during the operation of the device. That is, the fault analysis module monitors the main performance parameters of the rectifier device 11 during operation. If the parameters change during operation, they are compared with the normal operating parameters, the reasons for the parameter changes are analyzed, and a voice alarm signal is issued.

[0048] Please continue reading Figure 1 In some specific embodiments, the host computer 13 is also provided with an alarm light and an alarm speaker, and the alarm light and the alarm speaker are both communicatively connected to the fault analysis module. Specifically, the alarm light and the alarm speaker are communicatively connected to the fault analysis module in the host computer 13.

When a fault or abnormality is detected, the alarm light will emit a flashing signal, and the alarm speaker will emit a sound signal to ensure that the operator can quickly notice the system warning even in a noisy working environment. The setting of the alarm light and the alarm speaker provides instant visual and auditory alarms, significantly improving the safety monitoring capability of the remote centralized control electrolytic metal rectification system 10.
