Embodiment 1

[0043] figure 1 It is a structural block diagram of a law enforcement recorder upgrading system provided by an embodiment of the present invention, and is described in detail as follows:

[0044] A system for upgrading body-worn cameras based on the Internet of Things, including a management server and a plurality of body-worn cameras, the body-worn cameras have a built-in NB-IoT module and a lithium battery for powering the NB-IoT module, and the NB-IoT module Including a storage unit and a chip based on a cellular narrowband Internet of Things, the law enforcement recorder is connected to the narrowband Internet of Things through an NB-IoT module;

[0045] The management server broadcasts an upgrade instruction to the body camera;

[0046] After the law enforcement recorder receives the upgrade instruction, it packs the internally stored firmware version number, model and device manufacturer name to generate an upgrade data packet, and returns the upgrade data packet to the...

Embodiment 2

[0078] The embodiment of the present invention describes the implementation process of the management server sending the upgrade file corresponding to the hash value of the upgrade information to the law enforcement recorder, which is described in detail as follows:

[0079] The management server counts the number of selected upgrade files corresponding to the hash value of the upgrade information;

[0080] Sorting the times of selection, and selecting the upgrade file with the largest number of selections;

[0081] The upgrade file selected the most times is sent to the law enforcement recorder through the NB-IoT base station.

[0082] Wherein, the management server first sends the upgrade file with the largest number of selections to the NB-IoT base station, and then sends the upgrade file with the largest number of selections to the law enforcement recorder through the NB-IoT base station.

[0083] In the embodiment of the present invention, sending the upgrade file select...

Embodiment 3

[0085] The embodiment of the present invention describes another implementation process in which the management server sends the upgrade file corresponding to the hash value of the upgrade information to the law enforcement recorder, which is described in detail as follows:

[0086] The management server obtains the generation time of the upgrade file corresponding to the hash value of the upgrade information;

[0087] Sorting the generation time of the upgrade files corresponding to the hash value of the upgrade information, and selecting the latest upgrade file;

[0088] Send the latest upgrade file to the law enforcement recorder through the NB-IoT base station.

[0089] Wherein, the management server first sends the latest upgrade file to the NB-IoT base station, and then sends the latest upgrade file to the law enforcement recorder through the NB-IoT base station.

[0090] Optionally, as another implementation manner of the embodiment of the present invention, the latest u...

Abstract

The invention is applicable to the software field, and provides a law enforcement recorder upgrading system and a law enforcement recorder upgrading method based on the internet of things. The systemcomprises a management server and a plurality of law enforcement recorder, wherein the law enforcement recorder is built with NB-IoT Module, The NB-IoT module consists of a memory unit and a cell-based narrow-band Internet of Things chip. The law enforcement recorder uses NB-IoT module connects to narrowband Internet of things; The law enforcement recorder returns an upgrade data packet to the management server; The management server sends an upgrade file corresponding to the hash value of the upgrade information to the law enforcement recorder; The law enforcement recorder receives the upgrade file, copies the upgrade file to the preset directory, starts the preset loading program bootloader, loads the upgrade file from the preset directory, and sends the upgrade success information to the management server after the upgrade is completed; The management server receives the upgrade success information and stops sending the upgrade file corresponding to the hash value of the upgrade information to the law enforcement recorder. The invention is conducive to improving the upgrading efficiency of the law enforcement recorder.

Description

technical field [0001] The invention belongs to the field of software, in particular to a law enforcement recorder upgrading system and a law enforcement recorder upgrading method based on the Internet of Things. Background technique [0002] Law enforcement recorder is also called police law enforcement recorder or field law enforcement recorder. Integrating the functions of digital camera, digital camera and intercom transmitter, it can digitally record dynamic and static scene conditions during the law enforcement process, which is convenient for public security officers to use in law enforcement in various environments. [0003] However, the existing technology cannot complete the precise upgrade of the law enforcement recorder, which is not conducive to improving the upgrade efficiency. The reason is that the existing technology mainly adopts online point-to-point or local upgrade methods, and batch upgrade methods cannot be used. As a result, once the requirements of ...
