NIPm-500A data acquisition and transmission instrument is a new generation of environmental monitoring and pollution source monitoring special data acquisition device. It is designed according to industrial standards and specially optimized for various requirements of environmental monitoring. It is equipped with a rich and complete communication interface, supports Technology LAN, Ethernet, 4G wired and wireless communication methods to meet the requirements of long-distance communication in different on-site environments.

The NIPm-500A data acquisition and transmission instrument takes the embedded controller as the core, and transmits the data and status of the collected on-site monitoring instruments to the monitoring center server through the wired or wireless transmission network for monitoring by the environmental protection authorities; at the same time, the NIPm-500A data acquisition and transmission instrument It can respond to the control instructions sent by the monitoring center server through the transmission network, and then control the monitoring instrument according to the Modbus TCP protocol according to the instructions.

1. Abundant data interfaces: 2 isolated RS-232, 4 isolated RS-485, 16 high-precision analog acquisition, 14 isolated switch acquisition, 4 relay output and 4 switch output;
2. Multi-center communication: support multi-center communication, can communicate with multiple back-end servers according to different protocols at the same time, and each server can adopt different communication methods;
3. Control function: Respond to the control instructions sent by the monitoring center server through the transmission network, and then control the monitoring instrument according to the Modbus TCP protocol according to the instructions. It can set sampling time, alarm film value, proofreading clock, reset password, remote start sampling/encrypted sampling and other functions.
4. Communication security function: communication command password verification mechanism, password can be set. With watchdog recovery, it can be embedded in firewall protection software (Firewall). With IP address filtering function, to prevent the invasion of sick and illegal users.
5. Automatic operation: NIPm-500A data acquisition and transmission instrument will run automatically after connecting to the power supply, without any operation and setting. Unattended automatic work. Remote maintenance: NIPm-500A data acquisition and transmission instrument can complete its configuration, configuration, debugging and diagnostic functions by remote operation.
Data acquisition and processing: The working parameters can be set, the field meter data can be automatically collected at high speed, and the validity of the data can be judged after the data collection. The upper and lower limits of the data alarm can be set.

How the instrument works
The NIPm-500A data acquisition and transmission instrument collects the data of the production and pollution control equipment of the enterprise through the analog channel, switch channel, RS232 or RS485 digital channel, and transmits the data and status of the collected on-site monitoring instrument to the monitoring device through the wired and wireless transmission network. At the same time, it can respond to the control commands sent by the monitoring center reporter through the transmission network.
