1.1 System Overview
SPD-U03_1 embedded integrated monitoring host, with standardized interfaces such as Ethernet and RS485/, and a standard industry 19 inch rack mounted Anwen structure. The power supply of the external sensor device is provided by the monitoring host, without the need for additional power supply. Combined with dynamic environmental software, it can achieve power distribution monitoring, UPS monitoring, power outage monitoring, air conditioning monitoring, water leakage monitoring, video monitoring, access control monitoring, temperature and humidity monitoring, smoke detection monitoring, anti-theft monitoring, etc. When an alarm occurs, various alarm methods such as sound and light alarm, SMS alarm, telephone voice alarm, email alarm, etc. can be implemented. Implement monitoring alarm and linkage control functions, embedded with WEB software. Designed for integrated monitoring of power, environment, security, and network in unmanned sites, warehouses, and other scenarios, where users can view environmental, device parameters, alarms, reports, and other information through the IE browser. We have achieved unified monitoring of equipment in the computer room, reduced the burden on maintenance personnel, improved system reliability, and confirmed the scientific management location of the computer room.


1.2 Main functions
Comprehensive management. Monitor all environmental equipment in the computer room to enable operators to promptly detect equipment failures or hidden dangers, and take timely measures based on processing prompts to reduce unnecessary losses. Monitor the status of the power distribution system, monitor the working status of each switch in the primary and secondary power distribution of the power distribution system, and visually display the incoming voltage, current, frequency and other parameters of the power distribution system in graphics or numerical values on the interface. Historical curves can be recorded to monitor the operation status of the UPS system, comprehensively diagnose the condition of each component of the UPS, and monitor the voltage, current, frequency and load effective peak index of rectifiers, inverters, batteries, bypass and other components.
Monitor the operation status of the air conditioning system, monitor the status and parameters of the internal components of the air conditioning, operate the air conditioning on and off, and set the temperature and humidity settings of the air conditioning. When an event or malfunction occurs in the air conditioning system, the system automatically switches to the alarm screen and sends a voice alarm and water leakage detection system to monitor areas with water pipes or sources in the computer room (such as the air conditioning unit's inlet, outlet, and radiator) to prevent water leakage.
1.3 Product Features and Interfaces
（1） Adopting industrial grade CPU processors.
（2） Easy to expand: Expandable card insertion, plug and play, suitable for modular computer rooms without any jumper wires.
（3） Easy installation: Standard 1U rack mounted design for installation.
（4） External self power supply: Equipped with an external power supply interface, it supports direct power supply to devices and simplifies wiring.
（5） Stable operation: Industrial grade component selection, chassis all steel structure design.
（6） Unique services include the following
1) The secretary reminder service can periodically (daily/weekly/monthly) report the working status of the monitoring system through SMS, allowing customers to understand whether the computer room has been functioning normally in the recent period, and whether sensors (temperature, water leakage, smoke, etc.) have triggered alarms.
2) System monitoring service notifies customers when the system's setting parameters change to prevent monitoring failures caused by non-human factors. High stability system+super strong error correction creates a highly reliable system!
1.4 Open System
We provide customers with open data interfaces that support the MODBUS-RTU protocol; SNMP protocol, MODBUS-UDP protocol, MODBUSTCP protocol, customers can conduct secondary development and provide relevant technical support.
