In the underground parking lot of the commercial center, due to potential hazards such as vehicle exhaust and possible gas leakage, a combined solution of industrial touch management hosts and online gas detectors has been introduced. Multiple gas detectors are installed in different areas of the parking lot to monitor the concentrations of gases such as carbon monoxide and methane in real time, and the data is synchronized to the industrial touch management host. The large LCD screen of the main unit clearly displays the gas names, concentrations, times and other parameters at each point, providing 24-hour continuous monitoring. Once the gas concentration in a certain area exceeds the standard, the main unit will immediately trigger an alarm and can also link with text messages to alert the management personnel. Its features of supporting signal access from multiple brand devices and password protection to prevent misoperation make the gas safety management in parking lots efficient and worry-free, building an invisible safety barrier for both car owners and property management.
