A remote meter reading system was designed based on LoRa wireless transceiver and pic24 series microcontroller. Compared with current domestic meter reading system, this system has the advantage of long transmission distance and simple routing structure. The design of the system includes the model selection of hardware and software framework and the communication protocols. The network of the system is composed of two types of devices (collector and concentrator) with high modularization, which makes it possible to be used in wide range of situations. The key of software design is a task scheduler used time-based improved cooperative scheduling mechanism. The system is capable to manage the data of users' meters in a certain scope with high efficiency in real time, improving the work efficiency and accuracy.
