Project Overview

CITIC Bank Luoyang Branch was established on August 6, 2008. It is the first secondary branch of CITIC Bank in Henan. With CITIC Bank's professional brand, international vision, sound service network and diversified business advantages, CITIC Bank Luoyang Branch has achieved rapid development since its opening. The design scope of this project is the fire power load double power circuit of CITIC Bank Building, a total of 47 dual power distribution boxes. In this project, a dual power supply voltage signal sensor is installed in the fire load distribution box, and the fire equipment power state monitor is installed in the fire control room, and the system adopts a bus form networking.

1, user needs

This project requires the fire equipment power monitoring system to monitor the faults and abnormal conditions of the power supply of the fire-fighting equipment of CITIC Bank Building, and promptly alert the relevant personnel to eliminate these hidden dangers to prevent fire-fighting equipment from being available when the fire occurs, and the equipment cannot be normal. Put into 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 standards

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"

3, the solution

3.1 System Structure

The fire protection equipment power monitoring system of CITIC Bank Building 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 one RS485 bus and DC24V power cable are connected to the sensors in the field distribution box. The system topology is as follows:

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: can be manually eliminated, when there is an alarm signal input again, can start again

5, the alarm light signal: the red LED indicator is always on

3.2.2 Control output function

1. Remotely operate the alarm relay 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 main power supply undervoltage (≤80% main power supply voltage) or overvoltage (≥110% main power supply 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 obviously 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, can start again

7, fault alarm light signal: yellow LED indicator is always on

8. During the fault period, 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-test 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

Luoyang CITIC Bank Building fire equipment power monitoring system can monitor the power of fire equipment in real time, by detecting the voltage, current, switch status and other related equipment power information of fire equipment, to determine whether the power equipment has open circuit, short circuit, over voltage Fault information such as 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.

Musk Ketone (cas no.81-14-1) is a nitrated ketone. ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., h2). the amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (h2) and heat.
