Automation system is to produce and deliver goods and services with minimal human intervention. The implementation of automation technologies, techniques and processes improve the efficiency, reliability, and/or speed of many tasks that were previously performed by humans. Automation is being used in a number of areas such as manufacturing, transport, utilities, defense, facilities & operations.

CM4 Industrial is designed for Industrial Automation system, which offers 2 channels RS485 interface to receive the data from the sensors or other equipment, 3 channels high precision ADC can directly convert the analog signals, two channels isolated I/O can detect the status of digital I/O, a SPDT relay can control high power actuators.

Fish farming is a very common aquaculture project, because of its delicious meat, rich nutrition, wide variety, fish farming has not been eliminated by the aquaculture industry, but showing a rising trend of development. With the change of natural environment, many precious fish are on the verge of extinction. Artificial aquaculture is not only a way to meet market demand, but also the best way to preserve species diversity. However, the traditional aquaculture uses a large number of manpower, which wastes manpower and increases costs. And the energy is wasted due to untimely and incomplete information collection.

1. Under the background of efficiency priority, traditional buildings can't meet people's pursuit of intelligent office, energy saving and environmental protection.

2. In the trend of energy conservation and emission reduction and peak carbon dioxide emissions, the innovation of building management mode is becoming more and more urgent. Building is the main carrier of energy waste, and the energy consumption cost accounts for 30% of the operating cost. Energy conservation and consumption reduction have become the top priority of enterprise management.

3. The traditional building system is discrete, the management resources are wasted, each subsystem works and manages independently, and there is no information exchange between them, which leads to the problem of "isolated island" of information.
