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, loRa mainly operates in free frequency bands around the world, such as 433MHz, 868MHz, 915MHz, etc., and there have been proposals for applying LoRa technology to devices such as communication-type bracelets, watches, etc. When the intelligent scheduling system is applied to in-plant logistics scheduling and is equipped for logistics terminal personnel, how to ensure that the bracelet is available in the whole course of working time and improve the utilization rate of electric quantity while reducing the influence on the work of logistics personnel due to the fact that the volume and the weight of the bracelet, particularly the volume and the weight of a battery, are reduced, and the intelligent scheduling system is a problem faced when the intelligent scheduling system uses the LoRa technology.
Based on the above, the inventor of the present application proposes an energy-saving method of a LoRa bracelet for scheduling and a LoRa bracelet for scheduling, and a scheduling system based on the LoRa bracelet for scheduling.
Fig. 1 is an overall architecture of a dispatch system based on a dispatch LoRa bracelet. As shown in fig. 1, the scheduling system includes a scheduling service subsystem, a switch, at least one LoRa gateway, and a plurality of scheduling LoRa bracelets. Under the architecture, the LoRa bracelet for dispatching is distributed to each dispatching terminal personnel, and the dispatching service subsystem issues the logistics order in a broadcasting mode through the exchanger and the LoRa gateway.
Referring to fig. 2, the energy saving method for the LoRa bracelet for scheduling provided by the embodiment of the invention comprises the following steps:
step S1, initially setting the LoRa bracelet to be in a dormant state, and starting only the time base module.
And S2, the scheduling service subsystem transmits time synchronization information according to a preset time interval, and the scheduling LoRa bracelet receives the time synchronization information and automatically adjusts the bracelet time base.
In this step, the dispatching service subsystem is a control center of the dispatching system, and is implemented by hardware and software, and may be separately set in a dispatching office in a factory or integrated in the factory control center.
The specific synchronous time point can be set according to the preset time interval, when the synchronous time point is reached, a task for issuing time synchronous information is started, and when the synchronous time point is not reached, the system time monitoring process is returned; the time interval duration can also be set, and after a preset time interval duration is fixed, the task of issuing time synchronization information is started. And the time synchronization task of the service system is realized through monitoring the time.
And S3, determining CAD detection time by the LoRa bracelet based on the time base, starting CAD detection when the preset time is reached, and monitoring channel activity.
In this step, the CAD detection time is determined based on the time base, and is associated with the time base and the scheduled task. When the dispatching tasks are more, the CAD detection times are increased, and the detection time interval is shortened; when the dispatching tasks are fewer, the CAD detection times are reduced, and the detection time interval is longer. Time base calibration may also be tied to the detection time. When a scheduling task is issued, time synchronization information is issued at the same time, and CAD detection is determined to be started while the time base of the bracelet is automatically adjusted by LoRa bracelet receiving time synchronization information.
S4, determining the using state of the battery by the LoRa bracelet according to the CAD detection result; when no activity is detected, the process goes to step S6; when the logistics information is detected to be sent, a receiving radio frequency device arranged in the bracelet is opened to receive the logistics information.
S5, checking whether the received logistics information is matched with the current LoRa bracelet ID or not by the LoRa bracelet; if not, go to step S6; when matched, the received logistics information is interpreted.
In this step, the logistics information includes the names, the number, the departure places, the destination and the like of the goods.
Step S6, the LoRa hand-held device is kept in a dormant state.
In the step, when the LoRa bracelet enters a dormant state, the battery only supplies time base information for receiving without starting a receiving radio frequency device or an information reading module, and the battery is in a low-power consumption state, so that the electric quantity is saved, and the energy conservation of the LoRa bracelet is realized.
Based on the same thought, the embodiment of the invention also provides a LoRa bracelet for scheduling, as shown in fig. 3, wherein the LoRa bracelet for scheduling comprises: the device comprises a time base module, a control module, a CAD detection module, a receiving radio frequency device, an information interpretation module, a display module and a battery module.
