However, the types of the local meter reading communication module and the uplink communication module are not limited to the above-mentioned types.

Since the local meter reading communication module and the uplink communication module of the utility model all adopt a modular design, the matching local meter reading communication module and uplink communication module are selected according to the communication mode of the actual smart meter and the centralized collection terminal during use, and After the matching local meter reading communication module and uplink communication module are communicated with the processor through the module communication port and the processor communication port, the utility model can communicate with the smart meter and the centralized collection terminal. For example, if the communication mode of the smart meter is 470MHz micro-power wireless, then the 470MHz micro-power wireless communication module should be selected, and then connected to the processor communication port on the processor through the module communication port, thereby realizing the communication between the smart meter and the utility model 470MHz micro-power wireless communication; in the same way, if the communication mode of the centralized collection terminal is Ethernet, then the Ethernet communication module should be selected, and then connected to the processor communication port on the processor through the module communication port, thereby realizing the utility model and Centralized collection of Ethernet communications between terminals. Therefore, the utility model can realize the data transmission of multiple communication modes in the utility model by selecting different types of communication modules.

In addition, an uplink communication module that matches the communication mode of the centralized collection terminal is required. Therefore, as a preferred embodiment, the processor should be provided with at least four processor communication ports, so as to meet the communication requirements of the water, electricity, smart meters and centralized collection terminals. When they are inconsistent, the utility model can simultaneously collect the readings of the water, electricity and electricity smart meters and upload the readings to the centralized collection terminal.
