Description

Technical Field

[0001] The present invention relates to the technical field of monitoring of railway tunnel fire fighting water devices, and more specifically to an intelligent monitoring system for high-pressure fine water mist fire fighting water devices in plateau and high-altitude railway tunnels. Background Art

[0002] With the development of railway construction, there are more and more railway tunnels, which are getting longer and longer. According to statistics, as of 2020, the operating mileage of railways in China reached 1.45 million kilometers. Among them, 16,798 railway tunnels were put into operation, and the operating tunnels reached 19,630 kilometers. In the past five years, an average of more than 1,400 kilometers of tunnels have been newly added each year, which is equivalent to advancing at a rate of 4 kilometers per day.

[0003] Combined with China's national conditions and proceeding from reality, the design of disaster prevention and rescue in tunnels should be carried out in accordance with the principle of "prevention first, supplemented by fire fighting, combination of prevention and fire fighting, and relying on self-rescue", fully reflecting the concept of "people-oriented". At the same time, in view of the characteristics of fires occurring in railway tunnels, relatively reliable fire prevention measures and fire fighting means should be taken to ensure safety and reliability, advanced technology, economic rationality, and convenient and fast use and maintenance.

[0004] According to the requirements in the current national standards "Code for Fire Protection Design of Buildings" (GB50016-2006) and "Code for Fire Protection Design of Railway Engineering" (TB10063-2016). Most of the current railway tunnel fire fighting systems use high-pressure fine water mist fire fighting systems, and high-pressure fine water mist, also known as micro water droplets, requires a pressure greater than 10 MPa for spray generation. It is based on a positive displacement pump and usually uses a plunger pump for pressurization. For economic reasons, the pressure of the high-pressure fine water mist system and device is usually 10~20 MPa. High-pressure fine water mist can generate water mist with DV0.99<100μm under a pipeline pressure of not less than 10 MPa.

[0005] Since most of the current railway tunnel fire fighting water systems use high-pressure fine water mist systems or other forms of high-pressure fine water mist systems (such as mobile high-pressure fine water mist pumping stations), when using a high-pressure fine water mist system for monitoring, ensuring the pipeline pressure and the successful formation of fine water mist has always been a technical difficulty to be overcome.

[0006] Therefore, how to provide an intelligent monitoring system for high-pressure fine water mist fire fighting water devices in railway tunnels with high cost performance and reliability is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0056] At the same time, the intelligent monitoring device provides alarm for the failure information of the fire pump group and the fire hydrant box, as well as whether the device loses power or the signal is interrupted.

[0057] In addition, the intelligent monitoring device has the information communication function with the remote control platform, and has functions such as remotely reading real-time data, real-time status, historical data, fault alarm, early warning, etc. Through the deployment of the main device, the demand for the processing and computing power of the hardware equipment of the remote control platform can be effectively reduced, the network bandwidth demand can be reduced, and the construction scale of the central platform can be reduced.

The main controller of the high-pressure fine water mist fire protection water system reads the result information from the intelligent monitoring device through a standard protocol interface, and writes the read result information into the main station of the tunnel monitoring system through the network interface.

[0060] When the main controller of the high-pressure fine water mist fire protection water system reads the instruction from the main station of the tunnel monitoring system through the network interface, it drives the corresponding relay through the control digital quantity output module. The auxiliary contact of the relay controls the local control box of the high-pressure fine water mist fire protection water system to realize the on-off control function of the electromagnetic valves of each branch of the high-pressure fine water mist fire protection water system. During this period, the digital quantity input module is used to collect the working status information of the intelligent monitoring devices of each branch of the high-pressure fine water mist fire protection water, such as the switch status and remote / local status, and write it into the main station of the tunnel monitoring system through the network interface.
