0 Foreword

The Chenjia Town Binjiang Ecological International Community is located in the large leisure sports villa area of ​​Chenjia Town, Chongming, Shanghai. The land is adjacent to Dongtan Wetland and Beijiao State Guesthouse (planning) with abundant landscape resources. The project covers an area of ​​2,000 mu and the planned construction area is approximately 350,000 square meters. The project plans to include a star-rated resort hotel, a 6,000-square-meter golf club, an 18-hole standard golf course, and other commercial facilities. Chenjia Town Binjiang Community Hotel is a five-star hotel located in the center of the community.

The system can effectively predict and monitor the leakage and leakage due to leakage, and can accurately monitor the fault and abnormal state of the electrical circuit. It can discover the fire hazards of the electrical fire and promptly remind the personnel to eliminate these hidden troubles. It helps enterprises to save labor costs and improve work efficiency.

1 System Requirements Analysis

Detection of leakage current, over current, over temperature and other signals, sound and light signal alarm, accurately report the fault line address, monitor the changes in the point of failure. Store various fault and operation test signals to show system power status.

Reference standard: This system complies with the People's Republic of China national standard GB14287.1-2005 "Electrical fire monitoring system Part 1: Electrical fire monitoring equipment".

2 system structure

Acrel-6000 electrical fire monitoring system is an independent research and development by the company to receive residual current electrical fire detectors and other field equipment signals to achieve the alarm, monitoring, control, and management of the protected electrical circuit running on the computer's industrial level Hardware/software system. This system is applied to fire control centers in large shopping malls, living quarters, production bases, office buildings, shopping malls and hotels, and remotely measures, remotely adjusts, remotely controls, and remotely detects the detectors scattered in buildings to facilitate monitoring and management. The system uses a standard Modbus field bus to connect detectors with communication functions. When the detected parameters in the field protection circuit exceed the alarm setting value, it can send alarm signals, control signals, can indicate alarm locations and save alarms. information.

There are 29 ARCM-J1 residual current meters on the site of the Chenjiazhen Riverside Ecological International Community Hotel, which are distributed from the negative to the sixth floor. The field instrument is connected to the Acrel-6000 wall-mounted electrical fire monitoring system via a bus. This system has the advantages of convenient installation and transportation, high cost performance, and easy maintenance.

The main equipment of Acrel-6000 electrical fire monitoring system is as follows:

Touch screen: TPC1062K
I/O module: Built-in remote intelligent I/O module
Sound and light alarm: Built-in buzzer, LED indicator

Standby power supply: built-in 500VA long-term UPS

Host panel component layout and function description

1: Alarm indicator (red), the indicator lights up when the system receives the monitoring alarm signal.

2: Fault indicator (yellow), the indicator lights up when the system receives a fault alarm signal.

3: Running indicator (green). The indicator is on when the system is operating normally.

The distribution of this system mainly uses a computer distribution network structure.

1) Station control management

Station management The management personnel of the electrical fire monitoring system are the direct windows of human-computer interaction and the top part of the system. Mainly by the system software and necessary hardware equipment, such as TPC1062K, micro-printer, UPS power supply and other components. The monitoring system software has a good human-computer interaction interface. It calculates, analyzes, and processes various types of data on the site, and responds to the on-site operations with graphics, digital displays, sounds, and indicators.

Monitoring host: used for data acquisition, processing and data forwarding. Provides data interfaces within or outside the system for system management, maintenance, and analysis.

Printer: System calls to print or automatically print graphics, reports, alarm records, etc.

UPS: Ensure the normal power supply of the computer monitoring system. When the power supply problem occurs in the entire system, ensure the normal operation of the station control and management equipment.
2) Network communication layer

Communication medium: The system mainly adopts shielded twisted pair, uses RS485 interface, MODBUS communication protocol to achieve real-time communication between the field device and the host computer.
3) Field device layer

The field device layer is the data acquisition terminal, mainly by the ARCM300-JI surplus electrical fire monitoring detector. Can monitor single-channel leakage current, each phase cable temperature signal, each channel has a broken line, short circuit detection function; with event storage function, alarm can record the time, type, parameters of the alarm occurred, according to the alarm record can analyze the use of the site The power situation provides a basis for eliminating faults. Using fieldbus communication technology, the upper computer management software can constantly monitor the operation of the site and discover alarm information in time. The standard MODBUS protocol can be connected to various standard systems; it has a high degree of integration, networking, a high degree of intelligence, and reasonable operating characteristics.

The distributed I/O controller connected to the fieldbus forms a data acquisition terminal and uploads the collected data to the data center. The measuring instruments are responsible for the most basic data collection tasks. The data they monitor must be complete, accurate and transmitted to the monitoring host in real time. It is convenient for operating personnel to monitor the status of field equipment operation, fault alarms, etc. to effectively prevent the occurrence of fire accidents.

3 system function

This set of PC software Acrel-6000 electrical fire system. Mainly has the following function characteristic: The friendly man-machine contact surface, may gather the scene equipment the surplus electric current data and the temperature in real time and the time regularly, and has the warning prompt sound and light alarm and so on the function. The customer can set the alarm temperature value and leakage current value according to actual needs. When the alarm fault is removed, it can be reset remotely. The system can record alarm events, dates, alarm values, and over-line values ​​and generate reports that can print alarm event records.

1) Data Acquisition and Display

 

The on-site ARCM300-JI acquisition data is uploaded to this interface. The customer can modify the name of the circuit as required. The real-time value of the residual current of the corresponding cabinet can be displayed in the grid. Three-way temperature values ​​can be periodically updated. When the measured value of the residual current is greater than the alarm setting, the system alarm status indicator will flash automatically. The alarm prompt scroll bar at the bottom of the interface will automatically prompt the name of the alarm loop, which is convenient for the operating personnel to check and handle the fault.

2) Parameter setting and reset

   

   This interface mainly implements the ARCM300-JI remote adjustment function. The operating personnel can query the corresponding circuit's residual current over-line alarm value and temperature over-line alarm value in the parameter setting report. According to the actual needs of the site, the residual current over-line alarm value and temperature are increased. The line alarm value is set. At the same time, it can also reset the alarm instrument remotely. When the fault alarm is released, press the reset key to perform remote reset to facilitate the use of the user.

3) Alarm record

With event storage function, the alarm can record the time, type, parameter and alarm value of the alarm. According to the alarm record, it can analyze the cause of the fault to provide the basis for eliminating the fault. The alarm record can be printed.

4 Conclusion

With the development of smart buildings and the widespread use of electricity, people have become more aware of security awareness. The hidden dangers of public building installations are of great significance in preventing fires from occurring. Since the system was put into operation, more than 100 hidden dangers have been discovered and rectified, which provided a scientific basis for the hotel's fire management and was well received by customers.
