0 Project Overview

The Dalian auspicious e-project covers an area of ​​1.6 million square meters. It is located at the core of the intersection of Dalian City, Development Zone and Jinzhou District. The city must enter the eastward expansion. The project is located at the core entrance of the CBD of Jinma Road. The design scope of this project is the fire power supply circuit of 4#, 15#, 16#, 19#, 20# and underground garage A of Jixiang ejia Community. In this project, the fire power supply voltage signal sensor is installed in the fire load distribution box, and the fire equipment power status monitor is set in the fire control room, and the system adopts the 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 auspicious e-home fire-fighting equipment, and promptly alert the relevant personnel to eliminate these hidden dangers, to prevent fire, the fire-fighting equipment is available, and the equipment is not 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 standard

The system is designed to meet the manufacturing and testing standards listed below:

ISO/IEC11801 "International Integrated Cabling Standards"

3 solutions

3.1 System Structure

The auspicious e-home fire-fighting equipment power monitoring system adopts a two-layer structure networking mode of the fire equipment power state monitor + voltage sensor. According to the actual requirements of the project, the voltage sensor models for the fire protection equipment power monitoring system are: AFPM3-2AV, AFPM3-AV, and the fire equipment power status monitor model: AFPM100/B. The AFPM100/B is set in the fire control room, and four RS485 buses and DC24V power cables are connected to the sensors in the field distribution box. The system topology is as follows:

China Hardware Business Network

3.2 System function China Hardware Business Network

3.2.1 Monitoring alarm function

a. The monitored device power loop switch status

b. Working status of the monitored equipment power supply (voltage, current and alarm status information)

c. Alarm response time: ≤100s

d. Alarm sound signal: can be manually eliminated, can be started again when there is alarm signal input again

e. Alarm light signal: red LED indicator is always on China Hardware Business Network

3.2.2 Control output function

a. Remotely operate the alarm relay of individual or all monitored equipment

b. Monitor control output: normally open passive contact, capacity: AC250V 3A or DC30V 3A China Hardware Business Network

3.2.3 Fault alarm function

a. The connection between the monitor and the module (voltage/current signal sensor) is open, shorted

b. Monitor mains undervoltage (≤80% mains voltage) or overvoltage (≥110% mains voltage)

c. The connection between the monitor and its remote power supply is open and shorted.

d. When the above fault occurs in the monitor, it can send a sound and light fault alarm signal that is obviously different from the monitoring alarm signal.

e. Fault alarm response time: ≤100s

f. Fault alarm sound signal: manual elimination, can be started again when there is alarm signal input again

g. Fault alarm light signal: yellow LED indicator is always on

h. The normal operation of the non-faulty loop is not affected during the fault China Hardware Business Network

3.2.4 Self-test function

a. Connection check: open and short circuit of communication line and split power line

b. Equipment self-test: manual inspection or system self-test

c. Self-test time: ≤60s China Hardware Business Network

3.2.5 Alarm Recording Function

a. Record 10000 related fault alarm information

b. Alarm type: fault type, time of occurrence, fault description

c. Alarm event query

d. 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

Dalian Jixiang e home 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 the 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.

Cuplock Scaffolding

Cuplock Scaffolding

Cup-lock scaffolding is basically composed of Standards for vertical and ledgers for horizontal. While standards available in 9 regular sizes with cup joints welded at 0.5m intervals. The bottom cups are formed from high quality steel while the mobile top cups are malleable casting to provide the necessary hardiness on-site

Here comes our 5 types of Scaffolding systems:

- Cup lock Scaffolding(C-Lock Scaffolding)

- Ring lock Scaffolding

-Kwistage Scaffolding

-H-frame Scaffolding

-ID15 Scaffolding Tower, this type Scaffolding is the most widely used in construction, such like bridge.
