[0041] The role of the data acquisition and processing unit: receiving and processing signals from the gas sensor, converting them into digital data for analysis;

[0042] The role of the wireless communication module: transmitting the collected data to the central monitoring room or remote terminal for real-time monitoring and management;

[0043] The role of the early warning and display system: when the gas concentration exceeds the preset threshold, it sends out an audible and visual alarm signal and displays relevant information on the display screen, reminding on-site personnel to take emergency measures.

[0044] Based on the above systems, the actual use method and steps of the early warning of gas leakage in the sulfuric acid production process are as follows:

[0045] Gas detection: the gas sensor array continuously monitors the gas conditions in the workshop, and immediately converts abnormal gas concentration changes into corresponding electrical signal changes;

[0046] Signal conversion and transmission: after receiving the electrical signals from the sensor, the data acquisition and processing unit processes them through amplification, filtering and analog-to-digital conversion, etc., and converts them into digital signals. Then, through the wireless communication module, the data is transmitted to the central monitoring room or remote terminal;

[0047] Data analysis and judgment: after receiving the data, the central monitoring system uses special software algorithms to further analyze and compare the data. If one or more gas concentration indicators exceed the pre-set safety range, it is determined that a gas leakage event may have occurred;

[0048] Early warning trigger: when a gas leak is confirmed, the early warning and display system immediately starts, sends out an audible and visual alarm signal, and clearly displays the type, concentration and location of the leaked gas on the display screen, providing accurate guidance for emergency disposal.
