0 Project Overview
The second phase of Xingning City Administrative Service Center is located in Xingning City, Meizhou City. It is a three-storey public building with a total construction area of ​​9145 square meters, a total decoration area of ​​1748 square meters, a total building height of 13.2 meters, and a fire resistance rating of two. The fire power supply is designed according to the secondary load, and the fire control room is located on the first floor.
The design scope of this project is the power supply circuit of the second phase of fire protection equipment of Xingning City Administrative Service Center. There are 6 sets of three-phase dual power distribution boxes. The fire equipment power supply voltage signal sensor and fire equipment power status monitor are installed in the fire load distribution box. It is installed in the fire control room, and the system adopts bus form networking.
1 User requirements
This project requires the fire equipment power monitoring system to monitor the faults and abnormal conditions of the power supply of the second phase of the Xingning City Administrative Service Center, and promptly alert the relevant personnel to eliminate these hidden dangers and prevent the fire equipment from being powered out. Available, the device is not ready for use.
To facilitate on-duty monitoring and management, the central host should have the following main functions:
1) According to the power distribution drawings, monitor the fire equipment of each circuit and master the operation of the power supply of the fire equipment.
2) Fire equipment power monitoring system can realize a unified monitoring platform, which can obtain real-time data of all parameters in the system; intelligent management of the entire fire equipment power monitoring system can detect relevant information such as the voltage status of the fire equipment power supply. Therefore, it is judged whether the power supply of the fire-fighting equipment has fault information such as open circuit, short circuit, over voltage, under voltage, phase loss and error.
3) The host should monitor the alarm and fault alarm events with real-time printing of event number, monitoring location, event nature, alarm parameters and date and time data. The alarm event data should be stored separately, with an independent query interface, and can not be modified for fault liability analysis.
4) In addition to the above provisions, other functions and performance of the mainframe shall comply with the national standard GB 28184-2011 "Fire Equipment Power Monitoring System" and GB 25506-2010 "Fire Control Room General Technical Requirements" standard.
2 Reference standard
The system is designed to meet the manufacturing and testing standards listed below:
1) ISO/IEC11801 "International Integrated Wiring Standards"
2) GB/50198 "Technical Specifications for Monitoring System Engineering"
3) GB28184-2011 "Fire Equipment Power Monitoring System"
4) GB25506-2010 "General Technical Requirements for Fire Control Room"
5) GB/T 50314-2006 "Intelligent Building Design Standards"
6) GB50016-2006 "Code for Fire Protection of Building Design"
7) GB50303-2002 "Code for Construction Quality Acceptance of Building Electrical Installations"
8) JGJ 16-2008 "Electrical Design Code for Civil Buildings"
9) GB50052-2009 "Design Specification for Power Supply and Distribution System"
10) GB50054-2011 "Design Specification for Low Voltage Distribution"

3.1 System Structure
The fire protection equipment power monitoring system of the second phase of Xingning City Administrative Service Center adopts the two-layer structure networking mode of fire equipment power status monitor + voltage sensor. According to the actual requirements of the project, the voltage sensor model for the fire protection equipment power monitoring system is: AFPM3-2AV, and the fire equipment power status monitor model is AFPM100/B. The AFPM100/B is set in the fire control room, and two RS485 buses and DC24V power cables are connected to the sensors in the field distribution box. The system topology is as follows: .png)
3.2 AFPM100/B system function
3.2.1 Monitoring alarm function
1) The status of the power circuit switch of the monitored equipment
2) Working status of the monitored equipment power supply (voltage, current and alarm status information)
3) Alarm response time: ≤100s
4) Alarm sound signal: It can be manually eliminated. When there is alarm signal input again, it can be started again.
5) Alarm light signal: red LED indicator is always on
3.2.2 Control output function
1) Remote remote operation of alarm relays of individual or all monitored equipment
2) Monitor control output: normally open passive contact, capacity: AC250V 3A or DC30V 3A
3.2.3 Fault alarm function
1) The connection between the monitor and the module (voltage/current signal sensor) is open and shorted
2) Monitor mains undervoltage (≤80% mains voltage) or overvoltage (≥110% mains voltage)
3) The connection between the monitor and its separate power supply is open and shorted.
4) When the above fault occurs in the monitor, it can emit an acousto-optic fault alarm signal that is clearly different from the monitoring alarm signal.
5) Fault alarm response time: ≤100s
6) Fault alarm sound signal: manual elimination, when there is an alarm signal input again, it can be started again
7) Fault alarm light signal: yellow LED indicator is always on
8) During the fault, the normal operation of the non-faulty loop is not affected.
3.2.4 Self-test function
1) Connection check: open circuit and short circuit of communication line and split power line
2) Equipment self-test: manual inspection or system self-test
3) Self-testing time: ≤60s
3.2.5 Alarm Recording Function
1) Record 10000 related fault alarm information
2) Alarm type: fault type, time of occurrence, fault description
3) Alarm event query
4) Alarm record printing
3.2.6 Printing function
The monitoring system can print Chinese characters and print alarm events and time, fault events and time.
3.2.7 Silencing
In the event of an alarm such as an alarm or a fault, the speaker of the monitoring device will give a corresponding alarm sound to prompt, press the “mute†button to terminate the alarm, and the alarm light will be green. During the period, the staff can handle the faults. Everything returned to normal and the alarm light went out. If a new fault occurs, the silence indicator will turn off and the speaker will sound an alarm again.
4 Conclusion
The fire protection equipment power monitoring system of the second phase of Xingning City Administrative Service Center can monitor the power supply of fire-fighting equipment in real time. By detecting the voltage, current, switch status and other related equipment power information of the fire equipment, it is judged whether the power equipment has an open circuit. Fault information such as short circuit, overvoltage, undervoltage, phase loss, phase error and overcurrent (overload) are alarmed and recorded. The system is reliable, real-time and features digital, intelligent, networked, automated and continuous monitoring. Real-time reflection of the status of the power of the monitored equipment, and centralized display, which can effectively avoid the critical situation that the fire-fighting equipment can not work normally due to power failure during the fire, and maximize the reliability of the fire-fighting linkage system.
