[0002] Gas welding generally uses flames to heat the metal and welding wire at the joint of metal workpieces to melt them and achieve the purpose of welding. At present, gas welding has good adaptability to the welding of cast iron and some non-ferrous metals, and can play a greater role when welding is needed in places with insufficient power supply. Gas welding is widely used in the construction sites of thermal power plants. Commonly used combustible gases are mainly acetylene, liquefied petroleum gas and hydrogen, and the commonly used combustion-supporting gas is oxygen.

[0003] In order to ensure construction safety and prevent accidental injuries, there are certain requirements for the storage of oxygen cylinders and acetylene cylinders at the construction site, such as: oxygen cylinders and acetylene cylinders should be separated and placed vertically with anti-falling measures, and the safe distance between oxygen cylinders and acetylene cylinders should not be less than 8m; when using oxygen cylinders and acetylene cylinders at the same time, they should not be placed less than the safe distance; the distance from open flames is generally not less than 10 meters; combustibles are not allowed to be stacked within 10m around the storage warehouse for gas cylinders, open flame operations such as welding are not allowed, and smoking is not allowed; acetylene cylinders should be fixed when used to prevent tipping, and it is strictly forbidden to use them horizontally. For acetylene cylinders that have been placed horizontally, it is not allowed to open the gas directly for use, etc. In the actual construction process, operators are required to inspect whether the construction site meets the above requirements. However, there are a large number of gas cylinders on the site of large projects, the operation range is wide and the site environment is complex, and there is a problem of inadequate inspection. At the same time, operators may have a fluke and slack mentality, and management personnel may not conduct a comprehensive on-site inspection and miss some risks without mastering and rectifying them, which poses certain safety hazards.

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0019] Example: As shown in the attached Figure 1-3 As shown, the utility model describes an intelligent oxygen / acetylene cylinder storage and hot work safety monitoring and management system, including an intelligent sensor 2 arranged on an oxygen / acetylene cylinder 1, an intelligent ignition device 3 arranged on a welding gun, an intelligent fire extinguisher sensor 5 arranged on a fire extinguisher 4, an inflammable and explosive area protection sensor 7 arranged in an inflammable and explosive protection area 8, and a wireless intelligent terminal 6 arranged at a construction site.

[0020] The smart sensor 2 is used to detect the pressure and ambient temperature in the oxygen / acetylene cylinder 1, and can use an AST20PT pressure and temperature sensor to provide two independent voltage or 4-20mA outputs from the same device.

[0021] The intelligent fire extinguisher sensor 5 is used for positioning the fire extinguisher 4, and can adopt FAE laser rangefinder LS11 / 12FALS121FA.

[0022] The inflammable and explosive area protection sensor 7 is used to monitor whether there is a temperature-increasing area in the inflammable and explosive protection area 8, and an FT-H40K infrared temperature sensor can be used;

[0023] The smart sensor 2, smart ignition device 3, smart fire extinguisher sensor 5, and inflammable and explosive area protection sensor 7 are all provided with wireless transmission modules. The smart sensor 2, smart ignition device 3, smart fire extinguisher sensor 5, and inflammable and explosive area protection sensor 7 transmit data with the wireless smart terminal 6 through the wireless transmission module, and upload the on-site summary data to the cloud platform through the wireless smart terminal 6 for management personnel to check the on-site status at any time.

[0024] Preferably, each of the smart sensors 2, smart fire extinguisher sensors 5, and inflammable and explosive area protection sensors 7 is provided with an independent number, and each independent number corresponds to an address information, so as to facilitate the determination of the location of each sensor.

[0025] Preferably, the smart sensor 2 is provided with an alarm module.

[0026] Preferably, the smart sensor 2 is provided with a fingerprint recognition module.

[0027] The utility model adds a highly integrated intelligent sensor at the pressure reducing valve switch of the oxygen / acetylene cylinder. Each sensor is independently numbered and can measure the ambient temperature during the storage and use of the oxygen / acetylene cylinder, whether there are different types of cylinders within 5m, whether there are fire sources such as welding torch flames or cigarette butts within 10m, whether there are fire extinguishers within 10m, the type of gas in the cylinder, the cylinder pressure, the verticality of the cylinder to the ground and other index data related to safety regulations. The various data can be summarized to the on-site wireless intelligent terminal through the wireless transmission module; the management personnel first enter the name, fingerprint and other information of the welder who has passed the examination. During the hot work, the registered operator can only weld after the fingerprint is identified. At the same time, the intelligent terminal records the operation time. If the system detects that the on-site operation environment does not meet the hot work regulations, the gas supply is stopped by controlling the valve, and an alarm message is issued, and the violation record is uploaded. The gas supply can be restored only after the on-site rectification is qualified. The storage of oxygen / acetylene cylinders and hot work operations are fully controlled through the smart sensors on each oxygen / acetylene cylinder. When the hot work regulations change, parameters such as distance alarms and air pressure alarms can be set and updated through the platform.

[0028] During the storage period of oxygen / acetylene cylinders, smart sensors regularly collect data to check various parameters, generate records and upload them to the smart terminal. The smart terminal receives and processes the data transmitted by each oxygen / acetylene cylinder and forms a problem report, which is uploaded to the platform for management personnel to check the status of the cylinders at any time and rectify any problems. The administrator can also control the on-site smart terminal through the platform and obtain the data of each smart sensor at any time.

[0029] During hot work operations, the operator first logs in by entering his or her name or fingerprint. At this time, the smart gas cylinder checks various data through sensors. If any violation of the hot work requirements is found, the gas supply will be terminated, an alarm will be issued, and the illegal operation information will be uploaded. Normal gas supply will be restored after the illegal factors are rectified on site. The system can intelligently analyze data, generate existing problem reports and problem records for a period of time. Administrators can use the system to rectify on-site problems and provide training for illegal operations.

[0030] Compared with most existing traditional oxygen / acetylene cylinders, the utility model uses intelligent sensors to detect the type of gas in the cylinder, ambient temperature, verticality of the cylinder, distance from other sensors, presence of dangerous sources and fire sources around, and presence of fire extinguishers around. It determines whether the cylinder is leaking according to the change in the stored gas pressure. At the same time, the intelligent sensor is equipped with an alarm module, a wireless transmission module, and a fingerprint recognition module. When illegal operation by personnel is detected during hot work and fire sources are detected around the cylinder storage, an alarm for such problems will be issued. The gas supply valve will be closed during hot work. The cylinder can be used normally only after the operator has rectified and eliminated the problem. At the same time as the alarm is issued, the information on on-site violations and dangerous sources will be sent to the administrator's mobile phone through the Internet of Things for early warning. At the same time, on-site early warning records are generated. Managers can grasp the key points of on-site management through the early warning records every month, and focus on training personnel with weak safety awareness. Compared with ordinary gas cylinders, intelligent gas cylinders are safer and more convenient. After managers use the safety monitoring and management system, on-site safety problem management will be more accurate and comprehensive.

[0031] The use steps of the utility model are:

[0032] 1) Install an intelligent sensor 2 on the oxygen / acetylene cylinder 1;

[0033] 2) Install an intelligent ignition device 3 on the welding gun;

[0034] 3) Installing an intelligent fire extinguisher sensor 5 on the fire extinguisher 4;

[0035] 4) Install flammable and explosive area protection sensors 7 in flammable and explosive protection areas (fire operations are strictly prohibited) 8;

[0036] 5) A wireless intelligent terminal 6 is set up on site to collect data from various sensors on site and transmit it to the network platform via the Internet. Managers can log on to the Internet to view the status of various sensors on site, understand the site situation in real time and comprehensively, and check the site work records and problem logs, strengthen assessment and training in a targeted manner, improve personnel's operational awareness, and avoid accidents;

[0037] 6) Each sensor has data detection and data transmission functions, and can determine the danger on site according to the program and issue an alarm;

[0038] This system provides all-round control over the use of gas cylinders and the safety of on-site hot work operations, which is easy to manage and ensures the safety of hot work operations and the use of gas cylinders.
