One. Industrial 32-bit micro-computer chips are adopted, which have powerful functions, good stability and strong anti-interference ability.

Two. Embedded real-time operating system is used in the hardware.

Three. The monitoring host is separately configured with various sensors. Sensors can be selected according to the needs, refuse to bundle sales, hitchhiking sales, and spend the least money to achieve their required functions. The system achieves high performance-price ratio.

Four. the following services are unique

1. The small secretary's prompt service can report the working status of the monitoring system regularly (daily/weekly/monthly) by telephone to let customers know whether the computer room is normal in the recent period of time and whether the sensors (temperature, leakage, smoke, etc.) have alarms.

2. System monitoring service notifies customers when system setting parameters change to prevent monitoring failure caused by some non-human factors. High stability system + Super error correction makes high reliability system!

Five. Open system, we open data interface for customer prompt, customer can carry out secondary development, and provide related technical support.

Six. Simple installation, use and maintenance. Haiweishi Electronics has many years of experience in R&D and sales of computer room monitoring products. We know the needs of customers best. We strive to make the products easy to use from the source of design and manufacture. We strive to turn complex functions into simple operations, and strive to provide customers with complete functions and simple products.

Seven, service in place, we uphold the concept of customer first, to provide customers with 7X24 hours of sales and professional and technical services. SPD-200 series computer room monitoring host enjoys three-year warranty service, eliminating customers'worries and setting a precedent in the industry.

System diagram

1. DC 12V power input interface

2. 12V Battery Standby Power Interface (Automatic Start-up of Standby Power Supply in Case of Accidental Power Outage in Computer Room)

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

4. 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]

5. Four input interfaces for switching sensor (usually used to connect smoke sensor, water leakage sensor, door magnetism anti-theft sensor, etc.)

6. 1 Digital Temperature Sensor Interface (Connecting DS18B20 Digital Temperature Sensor)

7.4-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)

8. 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)

9. Acousto-optic alarm output interface (relay output load capacity is 250V/7A, can connect various types of acousto-optic alarm, to achieve on-site acousto-optic alarm function)

10.1 way programmable relay output terminal (relay output load capacity 250V/7A, the output relay can be programmed by the designated sensor control, such as can be set to temperature alarm when the output relay action will cut off the power supply room)
