Shanzhen II data acquisition instrument

Shanzhen II data acquisition instrument is a high-performance data acquisition and transmission device customized and developed by our company to meet the special needs of the environmental protection industry. The product adopts Samsung's ARM11 processor, embedded Linux operating system, graphical interface and real-time database, and complies with HJ / T212-2005 "Pollution Source Online Automatic Monitoring (Monitoring) System Data Transmission Standard" and HJ477-2009 "Pollution Source Technical Requirements for Online Automatic Monitoring (Monitoring) Data Acquisition and Transmission Instrument. Realized real-time dynamic monitoring of a meter, real-time display of the detection value and equipment status of the test instrument, and through analog signal interface, digital signal interface, digital interface and flowmeter, COD, PH meter, ammonia nitrogen, flue gas meter, Pollution treatment facilities and other instruments are connected, making monitoring of a meter more convenient, reliable and fast.
The data of the data acquisition instrument is transmitted to the environmental protection monitoring platform through the GPRS wireless network or the Ethernet wired network, so as to realize the remote transmission of data, remote monitoring and equipment anti-control. The device is equipped with a 4.3 'true-color TFT LCD display. It uses a graphical interface to intuitively and accurately display detection values, device status, device parameters, and historical data. The touch screen input is used to facilitate user input of parameters and provide future environmental protection implementation. Strong technical support.

Features of Shanzhen II data acquisition instrument:
 1. Fully intelligent. Unattended work automatically. Achieving anti-control of lower-end instruments.
 2. Multi-channel communication. GPRS / CDMA, Ethernet, etc., all communication methods can be used at the same time, with high communication reliability.
3. The factory standard configuration is LAN communication.
 4. Backup power system. When AC220 loses power, it will automatically switch to backup battery. Continuous working time is more than 8 hours.
 5, with alarm function. The alarm function is triggered according to the set alarm upper and lower limits, which can be reported to the central machine in time, and the monitoring data is automatically recorded at the set interval when the alarm occurs. And with alarm enable switch settings.
6. Display the working status of the lower instrument. The data acquisition instrument comes with 8 buttons, 8-bit digital tube and 8 status indicators. The working parameters can be set on site, indicating the operating status of the equipment, and the data collected on site can be displayed. Passwords are required to set the parameters.
7. Data storage adopts FLASH chip. Large data storage capacity, can store 8M historical data. According to the national standard communication protocol, minute data, hour data and daily data are saved.
8. Four configurable data serial ports (RS232 or RS485) are equipped as standard for data acquisition and control of the instrument.
9. All interfaces adopt photoelectric isolation design.
10. The communication protocol complies with the latest “Technical Specification for Data Transmission and Interface Standards of Online Automatic Monitoring (Monitoring) System of Pollution Sources” issued by the State Environmental Protection Administration and its compilation instructions. (HJ / T212-2005, released on February 1, 2006)
11.Transparent transmission
