Shanghai Jiading [Abstract]: When a fire occurs in a high-rise civil building, whether all kinds of fire fighting equipment can operate normally and play a role is one of the important conditions for the success of the initial fire fighting, and the stable and reliable fire equipment power supply is the guarantee for
the normal operation of fire fighting equipment.
Therefore, the monitoring system for the power supply of fire fighting equipment in high-rise civil buildings is crucial

.
In recent years, in order to solidly promote the special rectification action of fire safety of high-rise buildings, the Tongren City Fire Rescue Detachment has concentrated on investigating and rectifying the fire safety hazards of high-rise buildings in the city in accordance with the idea of "government leadership, industry focus, comprehensive treatment, and symptomatic and root causes", and preventing and curbing the occurrence
of fire accidents.
All departments coordinate and work together to promote the rectification of hidden dangers
.
All localities actively mobilize the competent departments of the industry, gather and form a work synergy, and supervise all kinds of high-rise civil buildings to clarify the main body of fire safety management in accordance with the "Regulations on the Fire Safety Management of High-rise Civil Buildings" and the current fire laws and regulations, clarify the responsibilities of fire control work and strictly implement them
.
At the same time, we regularly organize and hold centralized interviews with fire managers and building directors of high-rise buildings, inspect and guide the operation of fire control rooms, power distribution rooms and related fire fighting equipment, implement the "building chief, manager" system building by building, improve the level of fire safety management of high-rise buildings, and promote the independent management
of fire safety in high-rise buildings.
Keep a close eye on the key points and thoroughly carry out hidden danger investigations
.
All localities adopt the "one inspection and two core" model, independent inspection of streets and properties, on-site verification by the brigade, and verification by experts, and carry out hidden danger investigation and business guidance for the fire safety work of high-rise buildings such as fire fighting facilities, safe evacuation, pipe well blocking, electrical gas, building reconstruction and reuse, daily fire management, electric vehicle corridor charging, etc.
, and use the building information platform to register each high-rise building, and clarify the rectification responsibility and time limit
for the outstanding problems found 。 1 The characteristics and design requirements of high-rise civil buildings include fire fighting equipment in high-rise civil buildings, mainly including fire fans, fireproof roller shutter doors, fire emergency lighting, fire pumps, fire elevators, fire smoke exhaust and smoke fans, etc.
; To ensure that these firefighting equipment can be used properly in the event of a fire, it is also important
to monitor the power supply of these firefighting equipment.
Therefore, the state has also issued relevant standards to test the power supply of fire fighting equipment, as follows:  "Analysis of difficult points of building electrical design and mandatory provisions" 8.
29 What is the monitoring point setting principle of the power supply monitoring system of fire fighting equipment? A: In principle, the monitoring point of the power supply monitoring system of fire fighting equipment should be close to the end load side: (1) The main and backup power supply ends
of the dual power supply automatic switching box of all fire power supply systems.
(2) The power supply end of the distribution box at the end of all single-power supply (loop) power supply
.
 "Civil Building Electrical Design Standards" GB51348-2019 3 The setting and system composition of the power supply sensor of fire fighting equipment avoid the situation that the fire fighting equipment cannot operate normally due to daily management and inspection is not valued, in order to ensure that the fire fighting equipment has a reliable and stable power supply, in addition to strengthening daily inspection and maintenance, the fire control equipment power monitoring system is adopted, according to the clear requirements of the "General Technical Requirements for the Fire Control Room" GB25506-2010, The equipment set up in the fire control room shall include a fire power monitor
.
Among them, it is mandatory that
"the fire power monitor shall be able to display the working status and undervoltage alarm information of the power supply and backup power supply of the fire fighting equipment".
This is used to reduce and prevent fire hazards
.
In order to effectively monitor the power supply of various types of fire fighting equipment, the AFPM series of sensors can effectively monitor the power supply of various types of fire fighting equipment, timely alarm when abnormalities occur, and remind the duty personnel in the control room to check
.
According to the different types of on-site fire fighting equipment, the corresponding AFPM sensor types are also different, and the sensor specifications can refer to the following table
.
In order to monitor the sensors in different locations in a unified way, we usually need to set up a fire equipment power status monitor in the consumption control center to monitor
the power supply of fire equipment throughout the building.
The power supply status monitor of fire fighting equipment can be connected with multiple fire equipment power supply sensors through two buses to form a complete fire equipment power monitoring system, and the networking is shown in
the following figure.
Usually a two-bus circuit can connect 64 sensors, and the communication distance is within
500 meters.
The real-time working information and communication status of each sensor of the fire equipment power supply will be displayed on the monitor, and once there is a fault, the sound and light alarm will be issued for the first time, reminding the on-site maintenance personnel to go to the scene in time to view and maintain
.
The power supply status monitor of fire fighting equipment is generally installed in the elimination control room to receive the data of the sensor, and the on-site installation is shown in the following figure
.
Fire equipment power supply sensor is generally installed in the fire equipment power supply end electrical box, used to collect the voltage and current data of the fire protection electrical box, once there is an abnormality, timely reporting, on-site installation as shown in
the following figure.
4 Conclusion The design, installation and use of the power supply monitoring system of fire fighting equipment can significantly improve the reliability, stability and readiness of fire fighting equipment, so that fire fighting equipment can achieve the sense of "prevention first, prevention and elimination combined"
.
The use of fire equipment power supply monitoring system can effectively reduce the failure rate of fire equipment power supply, ensure the normal work of fire fighting equipment, and effectively protect the safety
of people's lives and property.
