Description

Technical Field

[0001] The invention relates to the technical field of heptafluoropropane gas monitoring, and in particular to an online monitoring system for a gas fire extinguishing bottle group and a use method thereof. Background Art

[0002] Heptafluoropropane does not contain chlorine or bromine and will not destroy the atmospheric ozone layer. Therefore, it is used to replace the environmentally harmful halon 1301 and halon 1211 as the raw material of fire extinguishing agent. Heptafluoropropane fire extinguishers are widely used as fire extinguisher materials in important places such as computer rooms.

[0003] The life cycle of HFC-227ea in the atmosphere is about 31 to 42 years. It does not leave any residue or oil stains after release and can be discharged through normal exhaust ducts, so it is very suitable as a fire extinguishing agent in data centers or server storage centers. Usually, these places will install a tank containing compressed HFC-227ea on the top of the floor. When a fire occurs, HFC-227ea is discharged from the air outlet of the tank, quickly exhausting the oxygen in the fire place and cooling the fire place, thereby achieving the purpose of extinguishing the fire.

[0004] Although heptafluoropropane is relatively stable at room temperature, it will still decompose at high temperatures to produce hydrogen fluoride, which has a pungent smell. Other combustion products include carbon monoxide and carbon dioxide. Once a fire occurs, carbon monoxide and carbon dioxide will cause pollution and damage to the human body and the environment, which is not good for human health.

[0005] At present, the functional rooms such as the engineering data room, communication room, and power battery room of a certain project's inter-provincial dispatching system are all equipped with HFC-227ea gas fire extinguishing devices. Currently, only manual inspections are used to monitor the pressure of the gas fire extinguishing device cylinder group. During the inspection, the front valve of the pressure gauge needs to be opened to connect the pressure gauge with the cylinder body before readings can be taken. In this way, the remote monitoring system for the gas fire extinguishing cylinder cannot be built in time. The existing online remote monitoring pressure devices must be installed when there is no gas in the cylinder, and cannot be applied to the inter-provincial dispatching system room.

[0006] Therefore, an online monitoring system for a gas fire extinguishing bottle group and a method for using the same are proposed. Summary of the invention

[0007] The purpose of the present invention is to provide an online monitoring system for gas fire extinguishing cylinder groups and a method for using the same. When it is impossible to install a pressure sensor on an existing cylinder, real-time monitoring of gas leakage in a fire extinguishing agent cylinder group of a gas fire extinguishing system can be achieved. That is, when the gas leakage in the cylinder group reaches a set value, detailed information will be reported to an Internet of Things terminal in a timely manner. There is no need to manually operate each cylinder one by one to observe whether the fire extinguishing agent cylinder group is normal, thereby ensuring that the on-duty personnel can quickly and effectively discover abnormal cylinder groups remotely and ensure the safety and reliability of the cylinders of the fire extinguishing system.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An online monitoring system for a gas fire extinguishing bottle group, comprising a fire extinguisher, a gas detection sensor for detecting heptafluoropropane, an Internet of Things transmission device, a data service platform and an alarm system;

[0015] Further, the gas detection sensor model is LB-MD4X.

[0016] Furthermore, the gas detection sensor is provided with a collection module for detecting heptafluoropropane.

[0017] Furthermore, it is provided with a conversion device, the conversion device is connected to the collection module, and the collection module is connected to the Internet of Things transmission device through the 485 protocol.

[0023] S2: The acquisition module connects to the IoT transmission device through the 485 protocol, and sends the collected gas data information to the IoT transmission device in real time, which is then sent to the data service platform by the IoT transmission device;

[0024] S3: The data service platform displays the monitored data in real time, so as to realize remote and precise monitoring of gas leakage in the gas fire extinguishing system cylinders in the dispatch center, which is convenient for remote viewing and control. If the real-time monitoring data of the machine room contains heptafluoropropane gas data, the valve threshold value is judged;

[0025] S4: If the preset valve threshold is exceeded, the data service platform connects to the alarm system, which notifies via mobile SMS and WeChat to implement an alarm, and can promptly notify the operation and maintenance personnel to check the status of the computer room and respond to gas leaks in a timely manner;

[0026] S5: If the preset valve threshold is not exceeded, the operating status, fault alarm and fire alarm of the computer room fire protection equipment are monitored in real time.

[0027] Furthermore, in step S3, the valve threshold is 8%-10% of the gas concentration.

[0028] Furthermore, the valve threshold is a gas concentration of 8%. In communication rooms and computer rooms, the fire extinguishing design concentration should be 8%.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] Collect the fire control host signals of each local station room, transmit them to the dispatch center after conversion, develop the fire monitoring system software platform, and monitor the operation status, fault alarm, fire alarm, etc. of the room fire equipment in real time;

[0031] The gas concentration sensor is used to monitor the HFC-227ea content in the computer room environment, and the monitoring data is transmitted to the fire monitoring platform to achieve real-time monitoring of HFC-227ea gas leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1:

[0036] See also Figure 1 , the present invention provides a technical solution:

The gas detection sensor is installed in a machine room equipped with a fire extinguisher to monitor the concentration of heptafluoropropane gas. The gas detection sensor is communicatively connected to the Internet of Things transmission device, and the Internet of Things transmission device is communicatively connected to the data service platform (through switches and transmission lines, the signals of the gas cylinder pressure intelligent transmission devices in each machine room are transmitted to the platform, and the monitored data is displayed in real time). The data service platform is communicatively connected to the alarm system for alarm prompts. The alarm system is communicatively connected to a mobile terminal and a mobile APP to facilitate remote reminders to operation and maintenance personnel, thereby realizing real-time monitoring of heptafluoropropane gas leakage.

[0038] The gas detection sensor model used is LB-MD4X, and a collection module for detecting heptafluoropropane is installed in the gas detection sensor for real-time monitoring and collection, which is timely.

[0039] The conversion device is connected to the acquisition module, and then the acquisition module is connected to the Internet of Things transmission device through the 485 protocol. The Internet of Things transmission device is a switch and a supporting transmission line, and the data service platform is the fire monitoring platform of the dispatching center.

[0040] like Figure 2 As shown:

[0041] In order to cooperate with the above system, a method for using the online monitoring system of the gas fire extinguishing bottle group is proposed, including the following steps:

[0043] S2: The acquisition module connects to the IoT transmission device through the 485 protocol, and sends the collected gas data information to the IoT transmission device in real time, which is then sent to the data service platform by the IoT transmission device;

[0044] S3: The data service platform displays the monitored data in real time, so as to realize the remote and precise monitoring of the gas leakage of the gas cylinder of the gas fire extinguishing system in the dispatch center. If the real-time monitoring data of the computer room contains heptafluoropropane gas data, the valve threshold value is judged, and the valve threshold value is 8% of the gas concentration;

[0045] S4: If the preset valve threshold is exceeded, the data service platform connects to the alarm system, and the alarm system notifies via mobile SMS and WeChat to implement an alarm;

[0046] S5: If the preset valve threshold is not exceeded, the operating status, fault alarm and fire alarm of the computer room fire protection equipment are monitored in real time.

[0047] Embodiment 2:

[0048] The difference between the embodiment 1 and the embodiment 1 is that: a method for using the online monitoring system for a gas fire extinguishing bottle group is proposed, comprising the following steps:

[0049] S1: Install a gas detection sensor for detecting heptafluoropropane in the machine room, and collect heptafluoropropane gas monitoring data in the machine room through a collection module on the gas detection sensor, so as to collect data information;

[0050] S2: The acquisition module connects to the IoT transmission device through the 485 protocol, and sends the collected gas data information to the IoT transmission device in real time, which is then sent to the data service platform by the IoT transmission device;

[0051] S3: The data service platform displays the monitored data in real time, so as to realize remote and precise monitoring of gas leakage in the gas fire extinguishing system cylinders in the dispatch center. If the real-time monitoring data of the computer room contains heptafluoropropane gas data, the valve threshold is judged, and the valve threshold is 9% of the gas concentration;

[0052] S4: If the preset valve threshold is exceeded, the data service platform connects to the alarm system, and the alarm system notifies via mobile SMS and WeChat to implement an alarm;

[0053] S5: If the preset valve threshold is not exceeded, the operating status, fault alarm and fire alarm of the computer room fire protection equipment are monitored in real time.

[0054] Embodiment 3:

[0055] The difference between the present invention and embodiments 1 and 2 is that: a method for using an online monitoring system for a gas fire extinguishing bottle group is proposed, comprising the following steps:

[0056] S1: Install a gas detection sensor for detecting heptafluoropropane in the machine room, and collect heptafluoropropane gas monitoring data in the machine room through a collection module on the gas detection sensor, so as to collect data information;

[0057] S2: The acquisition module connects to the IoT transmission device through the 485 protocol, and sends the collected gas data information to the IoT transmission device in real time, which is then sent to the data service platform by the IoT transmission device;

[0058] S3: The data service platform displays the monitored data in real time, so as to realize remote and precise monitoring of gas leakage in the gas fire extinguishing system cylinders in the dispatch center. If the real-time monitoring data of the computer room contains heptafluoropropane gas data, the valve threshold is judged, and the valve threshold is 10% of the gas concentration;

[0059] S4: If the preset valve threshold is exceeded, the data service platform connects to the alarm system, and the alarm system notifies via mobile SMS and WeChat to implement an alarm;

[0060] S5: If the preset valve threshold is not exceeded, the operating status, fault alarm and fire alarm of the computer room fire protection equipment are monitored in real time.

[0061] In the above embodiment, three different concentrations of heptafluoropropane gas are used. When the concentration of heptafluoropropane reaches 10% or more, it will cause discomfort to the human body. High concentration of heptafluoropropane will irritate and damage the human respiratory system, and may cause suffocation in severe cases.

[0062] Too high a concentration can also cause damage to the objects being extinguished, especially sensitive items such as electronic equipment;

[0063] According to the requirement that the fire extinguishing design concentration of heptafluoropropane should not be less than 1.3 times of the fire extinguishing concentration, and in actual use should not be greater than the toxic reaction concentration, the fire extinguishing design concentrations of different protection areas are different. Communication rooms and computer rooms should adopt 8%, oil-immersed transformer rooms should adopt 9%, and books, archives, etc. should adopt 10%;

[0064] It can be seen that this system is a system installed in a computer room, so the gas concentration does not exceed 8%. Embodiment 1 is the best embodiment.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
