Through intensive research, the inventor of the application finds that LoRa is an LPWAN communication technology, and is adopted and popularized as an ultra-long-distance wireless transmission scheme based on a spread spectrum technology. Currently, the LoRa mainly operates in global free frequency bands, such as 433MHz, 868MHz, 915MHz, and the like, and there is a scheme that applies the LoRa technology to devices such as communication bracelets and watches. When being applied to the in-plant logistics scheduling with it, being equipped with for logistics terminal personnel, how when reducing bracelet volume and weight especially battery volume and weight and reduce the influence to logistics personnel work, ensure that the bracelet is available in the whole journey of during operation time, improve the electric quantity utilization ratio, be the problem that faces when intelligent scheduling system uses the loRa technique.
