Problems solved by technology
The scanning head module itself does not have customized software from the manufacturer. It needs to provide the scanning head software to the customer and run on the CPU of the handheld PDA device. However, if the scanning head software is provided separately, the software is easy to be tampered with, and the scanning head module is also easy to be Pirated and imitated by other manufacturers
In order to solve this problem, several major scanning head manufacturers in the world are solving it by adding an MCU chip. The MCU is integrated into the scanning head module, and the anti-theft method is run on the CPU of the handheld PDA device. The scanning head software first communicates with the MCU in the scanning head module through customized or encrypted information, and then the MCU in the scanning head module communicates with the camera sensor. The program of the MCU in the scanning head module does not need to be modified, only encryption and decryption or The legality verification is enough, which can effectively solve the problem of pirated scanning head modules after customers get the scanning head software, but the problem is that an MCU chip needs to be added, which increases the cost a lot

Embodiment Construction
[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0038] It should be noted that the flow charts shown in the drawings are only exemplary illustrations, and do not necessarily include all content and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partly combined, so the actual order of execution may be changed according to the actual situation.
[0039] The block diagrams shown in the drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different networks and / or proces...

The invention discloses a scanning head module activation method, a user terminal and a system. The method comprises steps S1-S5 applied to the user terminal, wherein the user terminal comprises a scanning head module; the method comprises the following steps: S1, receiving and storing a first so library for activating a scanning head module; s2, receiving an activation instruction, calling a processor to load a first so library to read the serial number of the scanning head module and uploading the serial number to a server; s3, receiving a judgment result of the server on the validity of the serial number; s4, if the judgment result is valid, calling the processor to load the first so library to activate the scanning head module; and S5, if the judgment result is invalid, stopping running the scanning head module. The method for activating the scanning head module by reading the serial number of the scanning head module through software is designed, so that the scheme that an MCU chip needs to be added in the scanning head module is replaced, and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of scanning head modules, in particular to a method for activating a scanning head module, a user terminal and a system. Background technique [0002] Existing scanning head modules are usually composed of camera sensors, optical lenses, laser emitters, fill lights and peripheral circuits. The scanning head module itself does not have customized software from the manufacturer. It needs to provide the scanning head software to the customer and run on the CPU of the handheld PDA device. However, if the scanning head software is provided separately, the software is easy to be tampered with, and the scanning head module is also easy to be Other manufacturers pirated imitation and use. In order to solve this problem, several major scanning head manufacturers in the world are solving it by adding an MCU chip. The MCU is integrated into the scanning head module, and the anti-theft method is run on the CPU of the h...
