0 Introduction

Acrel-2000E/G power distribution room integrated monitoring system can be linked Real-time monitoring and analysis of temperature and humidity changes, ventilation conditions, indoor water accumulation and the operating status of equipment in the electrical room, active alarms for abnormal situations , and combined with the organic combination of various sub-functions, an abnormality-based The alarm linkage processing mechanism provides a technical means for timely detection of distribution network problems in the power grid. Combined with corresponding management means, the two-way interaction between the power distribution room and the management end is realized to achieve the purpose of \"two lows\" to reach and three highs\", that is, hReducing energy costs and reducing financial pressure, improving power supply quality, improving the return of funds and improving service quality provide a strong guarantee for ensuring the safe operation of power distribution equipment, making improving the quality of the power grid and providing better services to power users.

Training at Xiamen Youth Football Training Center In the field project, the system realizes the query, analysis, early warning and comprehensive display of various monitoring data to ensure the safety of the power distribution environment. In terms of intelligence, it realizes the remote measurement and remote signal data collection of the power and distribution monitoring systemem and the remote control points; in terms of data source management, it can monitor the operation of various equipment in the power supply and distribution room (including historical and real-time parameters), and request or print daily, monthly and annual reports according to the actual situation, improving work efficiency and staff is saved.

1 Project overview and requirements

The Xiamen Youth Football Training Center is said to be located on the west side of the core area of ​​Jimei New City, covering a total area of ​​nearly 100,000 square meters, mainly six standard football training fields, physical training rooms, medical rehabilitation room, etc., can satisfy 500 people training and living in the center at the same time.

The environment monitoring system is used in the official energy project of the training ground. The specific requirements are: intelligent monitoring auxiliary system including intelligent monitoring system screen, acquisition front-end computer, UPS power supply, video monitoring subsystem (cloud ball machine, ball machine), environmental monitoring subsystem (temperature, humidity, water immersion, smoke), control subsystem (lighting, air conditioning, dehumidifier, fan), door monitoring subsystem (card reader, door opening button, magnetic lock), security monitoring subsystem (dual detector).

2 Design standards and base

The comprehensive monitoring system of the power distribution room is composed of Various sensors, network equipment and computer equipment are interconnected and arranged. Due to different project scales, different functional performance, different degree of bimportance and different levels of user investment, the system can adopt different topological structures, but regardless of which topology is adopted, it adopts the \"station control management layer - network communication layer\". - on-site The hierarchically distributed design idea of ​​\"device layer\". This layered design meets the standards of the current communication system design and implementation, and can relatively complete the monitoring and control functions at each layer, that is, it can realize remote monitoring and control, and also cannot affect the current layer and the bottom layer when the top layer fails Function.

3hardware device selection

In this project, the screen of the intelligent monitoring system is located in the power distribution room. According to the project requirements and drawings, the equipment used in the project can be configured:

p style =\"box-sizing: border-box; margin-top: 12px; margin-bottom: 12px; padding: 0px; text-align: center;\">

Upload real-time data of temperature and humidity, water immersion status, smoke detection status and other data to the system host to realize the control of the power distribution room environment. The monitoring guarantees the safe and stable operation of electrical equipment.Among them, the power supply, induction line and signal output of the water immersion sensor are isolated from three parts: the temperature and humidity sensor has a 485 communication interface, which can communicate through the standard ModBus-RTU communication protocol; the water immersion sensor Monitor the water accumulation in indoor and outdoor cable ducts caused by the external environment and various factors; the camera is connected to the local video recorder through the network cable, and the real-time surveillance video and event information are stored in the local hard disk, and the video image is transferred through Ethjust sent to the control panel The host; the dual detection infrared and microwave detector overcomes the defect of single technology detector. When the sensors of the two sensing technologies detect the movement of the human body, it will sound the alarm and upload the alarm information to the background system; the access controller is connected to the magnetic lock, the door opening button, the card reader collects information, transmits the door lock information to the background system through the network cable, and can remotely control the door lock switch through the system.
