Description

Technical Field

[0001] The present invention relates to the field of gas alarm technology, and in particular to a multi-dimensional gas alarm system and an alarm method thereof for a workshop production line. Background Art

[0002] In industrial environments, gas is often used as industrial fuel to participate in the production process of materials. However, in the industrial production process, it is usually necessary to arrange special personnel to monitor the use of gas pipelines and gas equipment to avoid pipeline leakage. Once the gas leaks, it may cause fire, explosion, gas poisoning, etc., causing great harm.

[0003] At present, most monitoring methods are to install gas alarms on the production line. After a gas leak is detected, the gas alarm is used to sound an alarm. However, this method can only realize local alarms and cannot reflect the gas leakage situation inside the production line. It is difficult to achieve unified management of information, and the efficiency of point data processing is poor, resulting in low risk warning efficiency. Summary of the invention

[0006] Preferably, the positioning module includes a Wi-Fi positioning unit, a positioning node unit, a central control unit and a position display unit. The Wi-Fi positioning unit uses information such as Wi-Fi signal strength and delay for positioning, and combines the fingerprint positioning algorithm to achieve indoor positioning. The positioning node units are installed in different locations to form a coverage network for receiving and processing positioning signals. The central control unit integrates the data of the positioning module into the data acquisition module and associates it with the gas monitoring data. The position display unit displays the gas leakage location on the data acquisition module interface to provide intuitive location information.

[0007] Preferably, the valve cut-off module includes an electric actuator unit, a sensor feedback unit, a safety interlock unit and a status feedback and monitoring unit. The electric actuator unit uses an electric actuator as a valve cut-off device and realizes valve cut-off control by controlling the switching state of the electric actuator. The sensor feedback unit is integrated with the gas monitoring system, and when a gas leak is detected, the valve cut-off action is triggered. The safety interlock unit ensures the safety of the valve cut-off operation to avoid unnecessary safety accidents caused by misoperation or accidental operation. The status feedback and monitoring unit feeds back the status of the electric actuator to the data acquisition module to display the current switching state of the valve.

[0008] Preferably, the data acquisition module includes a data transmission unit, a data correction unit, a local storage unit and a historical data query unit.

[0010] Preferably, the alarm module includes an audible and visual alarm unit, a visual alarm unit, a mobile alarm unit and a remote alarm unit. When the threshold value is exceeded, the audible and visual alarm unit uses a high-decibel buzzer for on-site audible and visual alarm. When the threshold value is exceeded, the visual alarm unit uses a flashing light or an LED display screen for visual prompts. When the threshold value is exceeded, the mobile alarm unit sends an alarm message to relevant personnel via text message, phone call or mobile phone application. When the threshold value is exceeded, the remote alarm unit uploads the alarm message to the cloud platform for remote viewing and processing by management personnel.

[0011] Preferably, the backup power supply module ensures that the system can still operate normally when the main power supply is cut off.
