[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Embodiment 1

[0020] Refer to Figures 1 to 2As shown in the figure, a remote monitoring system for fluorine production equipment facilities includes:

[0021] The PLC control module designs the interface circuit between the PLC and the equipment facilities according to the interface types (analog quantity, digital quantity, communication interface) of the fluorine production equipment facilities. Appropriate cables and connectors are used to connect the PLC control module to multiple fluorine production equipment facilities respectively, for obtaining the working information of the fluorine production equipment facilities and processing the working information to obtain abnormal data information. The model of the PLC control module is Siemens' S7-1200, which is a programmable logic controller with high performance and strong expansion ability. Using this logic controller can effectively improve the system performance and stability. The system has flexible integration functions, flexible local control functions and remote control functions.

[0022] The fluorine production equipment facilities include the voltage and current detection circuit of the electrolytic anode and cathode of the hydrogen fluoride electrolyzer, the electrolytic heating power percentage detection circuit, the temperature sensors and liquid level sensors installed on the electrolyzer, the hot water pump frequency converter installed in the control cabinet, the temperature sensors installed on the absorption tower and purification tower, the electronic scale installed under the anhydrous hydrogen fluoride steel cylinder, the pressure sensor installed on the top of the buffer tank, the pressure sensor and valve state circuit on the pipeline, and the alarm installed in the duty room and the alarm is connected to the toxic and harmful gas detection probe.

[0023] The Internet of Things communication controller is connected to the PLC control module, for wirelessly transmitting the working information and abnormal data information to the Internet of Things platform.

[0024] The Internet of Things platform, namely the IOT cloud platform, is the core processing system for connecting and managing Internet of Things devices and realizing communication and data exchange between devices. The Internet of Things platform is wirelessly connected to the Internet of Things communication controller as a server using 4G communication, for storing and managing the working information and abnormal data information.

[0026] The monitoring system also includes a power supply module, which is respectively connected to the PLC control module and the Internet of Things communication controller, for supplying power to the PLC control module and the Internet of Things communication controller.

[0027] Temperature, pressure, frequency of the frequency converter, liquid level, voltage, current, and power percentage are collected through the analog input module inside the PLC and converted into digital data; the weight of the anhydrous hydrogen fluoride cylinder is weighed with an electronic scale, and the electronic scale is communicatively connected to the PLC control module through a serial communication interface, and the weight data is also transmitted to the inside of the PLC through communication; the alarm signal emitted by the toxic and harmful gas alarm is also read as digital data through the digital input module inside the PLC; the digital signal of the valve state is directly read as digital data by the digital input module of the PLC. The above digital data is compared with the preset values of the corresponding equipment and facilities inside the PLC control module. For example, during the fluorine production process, the working information value of the temperature sensor installed on the electrolytic cell is 101.5 degrees, and the preset value range for its normal operation is 90 - 110 degrees.

[0028] When the working information is not within the preset value range, it indicates that there is an abnormality in the operation of the equipment and facilities, thereby obtaining the abnormal data information of the fluorine production equipment and facilities with abnormal work, and transmitting the working information and abnormal data information of each fluorine production equipment and facilities to the Internet of Things communication controller, and then transmitting it to the IOT cloud platform for storage through the 4G communication of the Internet of Things communication controller.

[0031] The display large screen extracts the stored data from the IOT cloud platform through network communication and displays it on the large screen to show the corporate image to the visiting guests.

[0032] This remote monitoring system for fluorine production equipment and facilities can display various data through mobile phones, management machines, and display large screens, improving the level of safe production, enhancing the reliability of equipment operation, realizing remote monitoring, and ensuring the safety of personnel and equipment during the production process. The entire system realizes fully automated operation, with the advantages of convenience and portability, providing strong guarantees for the production management and safe production of the enterprise.
