Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a wireless door lock and a power consumption control method thereof. Background Art

[0002] Traditional mechanical locks cannot detect the lock status in time and can only rely on manual inspections to check the lock status. When a traditional mechanical lock is damaged, it cannot be discovered in time and is likely to cause property loss or personal safety threats. Wireless door locks are different from traditional mechanical locks. In addition to mechanical locks and anti-theft alarm functions, they can also combine communication and positioning technology to conduct all-round real-time monitoring of the lock status. Wireless door locks are used in industries such as vehicle transportation. They can open and close locks, enter and exit warehouses, patrol warehouses, and automatically upload records in a variety of ways to achieve integrated information monitoring of in-transit transportation and warehouse management, and optimize the transportation and warehousing management mechanism to a higher level.

[0003] Wireless door locks have mechanical and electronic components and require batteries to provide energy. Due to the limited internal space of wireless door locks, the battery size is limited and can only provide limited power. At the same time, in order to resist disassembly and prevent dust and water, wireless door locks generally adopt a sealed structure. The electronic components and batteries are enclosed inside the wireless door lock body structure, and the built-in battery cannot be quickly replaced. If the wireless door lock runs out of power during use, it will not work properly, which will have a great impact on the entire wireless door lock information detection. Especially in long-distance transportation of vehicles, the lock positioning information and door lock status information will not be obtained, which will cause major safety hazards in cargo transportation.

[0004] Therefore, when the battery storage energy is limited, how to effectively reduce the power consumption of wireless door locks becomes a key technical problem that needs to be solved. Summary of the invention

[0153] like Figure 8 As shown, the motion state control stage includes the following steps:

[0154] S801: Set the reporting interval of the Beidou positioning unit to T1=60s;

[0155] S802: The control module of the wireless door lock reports the positioning status to the remote monitoring platform every T1, and the reported information includes: indicating that the wireless door lock is in motion and cannot receive platform messages. At this time, the wireless communication unit, such as Cat1, turns on the PSM mode of periodic reporting, and can report the positioning information and motion status information to the remote monitoring platform, and the remote monitoring platform can accurately know the operating status and location information of the vehicle where the wireless door lock is located.

[0156] S803: Read the acceleration values ​​of the acceleration sensor in the x, y, and z directions for 10 consecutive times and take the average value of the ten times;

[0163] S809: If the absolute value of the acceleration is within 1 and the positive and negative values ​​are evenly distributed, it is considered that the vehicle where the wireless door lock is located is in a stable running state, and the acceleration sensor unit is turned on to enter S802.
