The AI interface shall support the access of current-type and voltage-type sensors, and have a built-in buzzer and temperature and humidity sensor. The intelligent data acquisition gateway shall support network registration through the RJ45 interface and camera image acquisition and monitoring capabilities.

Expansion Capability

The intelligent data acquisition gateway shall have expansion capability. Expansion shall be realized by plugging and installing expansion boards inside the intelligent data acquisition gateway. Without interface multiplexing, the expansion board shall have the following interface quantities: 8 AI interfaces, 8 DI interfaces, 4 DO interfaces, and 4 RS-485 interfaces.

Storage Capability

RAM: 512MB DDR3 RAM, 1GB Flash, storage space ≥32GB, memory card Class10 or above.

Basic Functions

1. Complete data collection of monitored objects such as power supplies, air conditioners, air conditioner controllers, shunt metering, step batteries, heat exchangers and various environmental quantity collectors through data interfaces. After bottom-layer parsing and intelligent processing, upload the data to the centralized monitoring center SC through wireless or wired networks.

2. Receive monitoring commands sent by the centralized monitoring center SC through the B interface, and send the received monitoring commands to the monitored equipment and environmental quantity collectors to realize the monitoring of the monitored equipment and environmental quantity collectors by the monitoring center SC.

3. Have the functions of data processing, storage and printing of various monitoring information (have the function of connecting portable devices for on-site maintenance operations).

4. Receive the clock calibration command sent by the monitoring center SC and perform clock calibration.

5. Have the ability of intelligent analysis of collected data to avoid system blockage and improve system response time.

6. Have logical analysis and control capabilities, and automatically execute relevant controls according to established strategies.

7. Have the ability of remote upgrade, program loading and protocol operation.

Communication Interface Transmission Rate

Serial communication RS-485/232/422, RS-485 interface default transmission rate: 9600bps. Optional transmission rates: 1200bps, 2400bps, 4800bps, 19200bps, 115200bps.

A Interface Communication Protocol

The base station intelligent power environment monitoring unit (intelligent data acquisition gateway) shall adopt the bottom-layer parsing method to parse and intelligently process the A interface communication protocol.

Base Station Image Monitoring

1. Image monitoring mainly monitors the image information of important positions of the base station.

2. Base station image monitoring cooperates with intelligent data acquisition gateways, surveillance cameras and other monitoring equipment to monitor the base station for anti-theft, fire prevention and prevention of man-made accidents. The surveillance camera is located on the base station side as an independent device. The base station intelligent power environment monitoring unit (intelligent data acquisition gateway) can control the access control, lighting and surveillance cameras to work in linkage.

3. The base station intelligent power environment monitoring unit (intelligent data acquisition gateway) shall have alarm linkage capability, that is, when an alarm endangering the safety of the base station (such as infrared, vibration, illegal entry, etc.) occurs, the lighting equipment will be automatically turned on, and the surveillance camera will be linked to take pictures.

4. The image monitoring equipment shall have a built-in clock for independent timing.

5. The image surveillance camera has a built-in 32GB memory card, Class10 or above.

6. The image surveillance camera reserves support for real-time video functions to facilitate the addition of video functions in the future.
