Application of industrial serial port server in intelligent community meter reading and payment system

1. Usage of original equipment:

Water meter reading and charging has always been a manual door-to-door service. As most family members are at work during the day, we can only read the meters at night or on weekends. However, there may be omissions, underreading or the owner is not at home, so we have to read the meters repeatedly, making the meter reading work too cumbersome.

2. Current usage:

With the popularization of modern intelligent devices, people's lives have been greatly facilitated. This case is a smart water meter reading system in a modern community in Shanghai. In Shanghai, where the economy is developing rapidly, people's lives are efficient and tense, and traditional door-to-door meter reading and door-to-door charging have become history. Using one GW21C-MAXI, a total of 12 smart water meters on 6 floors of a unit can be connected at the same time, and then the data can be uploaded to the community property through the community LAN, and then sent to the water company through the Internet. Make meter reading simple and controllable.

3. Product features:

GW21C-MAXI has 1 serial port, RS-485/422/232 interface optional, speed up to 115.2kbps. 1 10/100Mbps Fast Ethernet full-duplex adaptive network port. Provides Telnet, embedded browser, serial port control or window tools and other configuration methods. Provides C language software development kit for easy development and programming. RS-232 (15KV), RS-485 (12KV), Ethenet (2KV), power supply (10KV) 15KV ESD serial port surge protection.
