Remote Monitoring Solution for Fire Water Tanks in the Xiamen-Shenzhen High-Speed Rail Tunnel

System Requirements Analysis
According to the "Regulations for the Quality Inspection and Evaluation of Fire Protection Facilities Installation in Buildings in China"“GB 50974-2014 4.3.9clause” users need to display the fire water pool water level simultaneously in the on-site pump room and the fire control room,and both have high and low level alarms.According to fire regulations, it is crucial to ensure that the fire water pool and high-level fire water tank are full, andon-site display andthe importance of remote monitoring in the fire control center is paramount. If the fire control center does not have a liquid level indicator for the fire water pool and high-level fire water tank, according to fire regulations, there is a high risk of failing the quality inspection and acceptance of the building fire protection facilities installation. Therefore, it is necessary to monitor the real-time liquid level of the fire water pool tank in the fire control center, which requires the use ofWH311fire water tank liquid level display.

System Overview
WH311The liquid level sensor probe is directly placed at the bottom of the user's fire water pool tank,WH6installed for on-site display, and through a remote transmission module, the fire water pool tank level remote transmission signal is transmitted tothe fire control room, using2*1.5square shielded cable to connect,anotherWH6installed in the fire control room real-timedisplayreal-timeactual fire water level, and comes with a high and low level alarm system to ensure that the fire water level is always kept high.Simultaneously display the fire water pool tank water level on-site and in the fire control room, with

Project Description

Typical User Specific Needs ：

User:XiaMen-ShenZhen High-Speed Rail Tunnel

Demand:A section of the XiaMen-ShenZhen High-Speed Rail tunnel has2fire water pools, with a pool height of5meters. It is required todisplay on-site andfire control roomsimultaneouslydisplay the water level,andsimulate the water pool level display plus high and low level alarm.

Project Key Points Analysis:

1，2underground fire water pools, with a height of5meters;
2the fire water pool liquid level signalis required to be displayed on-site beforebeing transmitted4kilometers awayto the fire control room for display, using anti-interference design for remote transmission;
3not only real-time liquid level display is required, but also intuitive percentage light column to represent the fire water pool water level, and high and low level alarm is required.
