The agent terminal 30 establishes a data connection with at least one monitoring module 40 remotely. According to the utility model, the Internet of things agent terminal is arranged between the sensor and the monitoring module for path transmission, so that a large amount of data transmitted by the sensor is preprocessed and judged, and only abnormal data is sent to the monitoring module 40 for monitoring. So set up, because the geographical position between the sensor in thing allies oneself with agent terminal and the intelligent case becomes is nearer for data transmission is stable, and data loss is less, and can realize quick response when discovering unusual data, realizes real-time response.

For example, one data conversion module can establish a communication connection with a plurality of sensors with a small data acquisition amount to receive data and perform data conversion. The advantage of the data conversion module not establishing a one-to-one correspondence with the sensors is that by reducing the number of data conversion modules, the power consumption and the occupied physical space are reduced, and the inefficiency of some data conversion modules is also avoided.
