Description
技术领域technical field
本发明属于消防设施中气体消防的物联网应用技术领域，特别涉及一种气体消防维护管理的远程监测系统。The invention belongs to the technical field of Internet of Things application for gas fire protection in fire protection facilities, and in particular relates to a remote monitoring system for maintenance and management of gas fire protection.
背景技术Background technique
在消防设施中，气体消防作为保护贵重设备的主要方法之一，重视气体灭火系统平时的维护管理显得尤为重要。常规的气体消防灭火系统有七氟丙烷气体灭火系统、IG541气体灭火系统、二氧化碳气体灭火系统等。气体灭火剂在灭火场所选择上有一定的要求，它对保护物来说造成灭火后的二次损害较小，但其灭火剂的储存压力较高，压力容积的储存受到环境温度的影响，部分气体灭火剂的泄漏会对人员产生毒害。随着“互联网＋”、物联网时代的到来，给气体灭火的自动检测、监测带来了新的发展。In fire-fighting facilities, gas fire-fighting is one of the main methods to protect valuable equipment, and it is particularly important to pay attention to the usual maintenance and management of gas fire-extinguishing systems. Conventional gas fire extinguishing systems include heptafluoropropane gas fire extinguishing system, IG541 gas fire extinguishing system, carbon dioxide gas fire extinguishing system, etc. The gas fire extinguishing agent has certain requirements in the selection of fire extinguishing places. It causes less secondary damage to the protected objects after fire extinguishing, but the storage pressure of the fire extinguishing agent is relatively high, and the storage of the pressure volume is affected by the ambient temperature. Leakage of gas extinguishing agent can be poisonous to personnel. With the advent of the era of "Internet +" and the Internet of Things, new developments have been brought to the automatic detection and monitoring of gas fire extinguishing.
从现状分析，气体灭火系统的日常维护管理存在一定的薄弱环节，主要靠人工的巡查，由人工判断压力值的状态。灭火剂钢瓶的压力下降，说明灭火剂的泄漏。一方面，影响了灭火剂灭火的浓度，需要定期补充；另一方面，泄漏的灭火剂对人员有危害。其消防管理和监督检查的技术手段缺乏创新、完善和提升。目前，有开发出一种气体消防物联网压力监测系统，它在启动装置上设差压式压力传感器，差压式压力传感器输出连接串口服务器络连接远程主机。但增加设置在启动装置上的压力传感器对原有气体灭火气体的可靠性有一定的降低，这种物联网压力监测系统需要破坏原有系统进行安装高压的压力传感器，可能涉及到系统的重新验收。还有开发出在气体钢瓶下安装称重设备，来判断钢瓶内气体是否泄漏。但对已经安装的钢瓶系统也造成较大的影响，特别是灭火剂的质量受到环境温度的影响，其称重的精度判断的准确性存在一定的问题。此外，目前研究的气体消防监测仅仅局限于平时气体消防钢瓶的气体灭火剂是否泄漏，对灭火状态下，瓶头阀是否能确保正常开启，气体管网内的压力这一结果的参数没有体现。From the analysis of the current situation, there are certain weak links in the daily maintenance and management of the gas fire extinguishing system, mainly relying on manual inspection and manual judgment of the state of the pressure value. The pressure drop of the fire extinguishing agent cylinder indicates the leakage of fire extinguishing agent. On the one hand, it affects the concentration of the fire extinguishing agent, which needs to be replenished regularly; on the other hand, the leaked fire extinguishing agent is harmful to personnel. Its technical means of fire management and supervision and inspection lack innovation, perfection and promotion. At present, a gas fire-fighting Internet of Things pressure monitoring system has been developed, which is equipped with a differential pressure sensor on the starting device, and the output of the differential pressure sensor is connected to the serial port server network to connect to the remote host. However, adding a pressure sensor installed on the starting device will reduce the reliability of the original gas fire extinguishing gas to a certain extent. This kind of IoT pressure monitoring system needs to destroy the original system to install a high-pressure pressure sensor, which may involve re-acceptance of the system. . In addition, a weighing device is installed under the gas cylinder to judge whether the gas in the cylinder leaks. But it also has a greater impact on the installed steel cylinder system, especially the quality of the fire extinguishing agent is affected by the ambient temperature, and there are certain problems in the accuracy of its weighing accuracy judgment. In addition, the current research on gas fire monitoring is only limited to whether the gas fire extinguishing agent in the gas fire cylinder is leaking in normal times. Under the fire extinguishing state, whether the bottle head valve can be opened normally and the pressure in the gas pipe network are not reflected in the parameters of the result.
