Acrel ANet Series Smart Gateway is an embedded hardware computer platform with multiple downlink communication interfaces and one or more uplink network interfaces. As a bridge between the acquisition terminal and the platform system in the information acquisition system, it can The protocol carries out data collection and summary of equipment terminals such as water meters, gas meters, electricity meters, and computer protection, and uses the corresponding protocols to forward the data of field equipment to the platform system.
