System characteristics

It adopts 32-bit industrial microcomputers with powerful functions, good stability and strong anti-interference ability. Embedded real-time operating system is used in the hardware. The monitoring host is separately configured from various sensors, and sensors can be selected according to needs, refuse to bundle sales, hitchhiking sales, spend the least money to achieve their required functions, the system achieves a high cost-effective small secretary prompt service, and can report the working status of the monitoring system regularly (daily/weekly/monthly) by telephone, so that customers can know whether the computer room is correct in the recent period of time. Often, whether the sensor (temperature, leakage, smoke, etc.) alarms occur. The system monitoring service notifies customers when the setting parameters of the system change, so as to prevent monitoring failure caused by some non-human factors. High stability system + Super error correction makes high reliability system!

There are many interfaces for monitoring host computer, including the following interfaces

DC 12V power input interface

12V Battery Standby Power Interface (Automatic Start-up of Standby Power Supply in Case of Accidental Power Outage in Computer Room)

RJ11 telephone line interface (when detecting sensor alarm, call the user's mobile phone or fixed telephone voice to inform the customer)

RS485 data communication interface (RS485 interface uses ordinary twisted pair to transmit data, has long communication distance [up to 1200 meters], strong anti-interference ability, strong expansibility [up to 128 devices using RS485 communication in parallel]

Four switch sensor input interfaces (usually used to access smoke sensor, water leakage sensor, door magnetism anti-theft sensor, etc.)

A Digital Temperature Sensor Interface (Connecting DS18B20 Digital Temperature Sensor)

4-way 0-20mA/4-20mA industrial current loop interface (can be used to connect temperature, humidity, voltage, current, speed, gas, dust and other sensors with all current loop output interface)

Infrared receiving/sending interface, which is equivalent to a learning infrared remote controller, can be used to control the air conditioning in the computer room (the system highly integrates the monitoring/control function of the air conditioning in the computer room, and automatically turns on the air conditioning when the temperature is too high)

The output interface of acoustooptic alarm (the relay output load capacity is 250V/7A, which can connect various types of acoustooptic alarm to realize the on-site acoustooptic alarm function)

The output terminal of a programmable relay (the output load capacity of the relay is 250V/7A), which can be programmed to be controlled by a designated sensor. For example, the output relay action can be set to cut off the power supply of the engine room when the temperature exceeds the limit alarm.
