Haitongda Industrial Wireless Air Environment Intelligent Detection System

Haitongda Industrial Wireless Air Environment Intelligent Measurement and Control System is an industrial wireless remote intelligent measurement and control equipment independently developed by Haitongda Technology. The online environment measurement and control cabinet system can monitor and control the equipment running in the designated area of ​​the remote site to achieve real-time collection of on-site temperature, humidity, carbon dioxide, noise, light, soil moisture, dissolved oxygen, oxygen, ammonia, pH value, etc. and control of on-site equipment such as irrigation and fans.

3. System functions:

1. Collection function: can collect sensor data of various RS485 interfaces or analog outputs;

2. Control function: It can control various on-site equipment with switch output control, such as water pumps, fans, etc.;

3. Wireless function:

A. The communication distance is 0-25Km and Haitongda industrial wireless communication module is used to achieve remote transmission;

B. When the communication distance is above 20km, Haitongda GPRS or 3G wireless communication module is used to achieve remote transmission;

4. Communication function: The measurement and control terminal can be set to actively report data to the monitoring center, or it can be set to be inquired by the monitoring center. There are two types of active reporting mode: one is reporting when the on-site status changes, and the other is regular reporting. In the inquiry mode, the measurement and control terminal reports data only when the monitoring center issues an inquiry command.

5. Storage function: The measurement and control terminal has a power-off storage function, and the data will not be lost when the power is off. The measurement and control terminal can store more than 30,000 historical records, and historical data can be queried in a timely manner and generated into Excel reports.

6. Alarm function:

A. Fault alarm: When the signal line between the water level, pH value, flow rate and other sensors and the measurement and control terminal is interrupted, the monitoring software will automatically pop up an alarm window.

B. Over-limit alarm: The upper and lower limits and increase alarm can be set for monitoring data such as water level, pH value, instantaneous flow, etc. The alarm information can be sent to the monitoring center and the alarm SMS can be sent to the administrator's mobile phone.

C. Change alarm: When the measurement and control box is illegally opened or there is a power outage on site, an alarm message can be sent to the monitoring center and an alarm text message can be sent to the administrator's mobile phone.

7. Power supply function: The measurement and control terminal can be equipped with batteries, which can be charged by solar panels, so that the on-site measurement and control terminal can be unattended.
