Problems solved by technology

[0002] Most of the existing electronic unlocking keys have built-in power supply batteries, and the use of batteries has strict environmental requirements. Low temperature environments will lead to insufficient battery power and affect the unlocking effect. Therefore, the use of unlocking keys with batteries is subject to certain limits.
In addition, for the sake of safety, electronic keys are generally fixed with password data before leaving the factory, which is inconvenient for later password modification, and it is difficult to crack the password if the key is lost

Abstract

The invention provides an electronic coded key comprising a wireless power receiving module, a control unit, a memory unit and a wireless communication module, wherein the output end of the wireless power supply receiving module is connected with the control unit and the wireless communication module; the control unit is connected with the memory unit and the wireless communication module; a code set by a user is written into the memory unit by means of a writing flash; the wireless power receiving module receives the power provided by a wireless power emitting module in an electronic lock and supplies the power to the electronic coded key; and the control unit reads the code memorized in the memory unit and transmits the code to the electronic lock by the wireless communication module. The electronic coded key has the following advantages that the service life problem of a power supply does no need to be considered due to the non-embedded-memory design, and meanwhile, the electronic coded key has an initial password protection function.

Description

technical field [0001] The invention relates to an electronic key, in particular to an electronic key powered by a wireless power source and having a password storage function. Background technique [0002] Most of the existing electronic unlocking keys have built-in power supply batteries, and the use of batteries has strict environmental requirements. Low temperature environments will lead to insufficient battery power and affect the unlocking effect. Therefore, the use of unlocking keys with batteries is subject to certain limits. . In addition, for the sake of safety, electronic keys are generally fixed with password data before leaving the factory, which is inconvenient for later password modification, and it is difficult to crack the password if the key is lost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe and reliable electronic password key that does not need a built-in battery for power supply...
