Bluetooth Security Device Low Power Standby Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth security devices have limited power savings in low-power dissipation standby mode, resulting in insufficient prolongation of standby time.
Innovation Solution
A method where the security module sets itself to a low-power dissipation standby mode immediately after processing data and returning the result to the Bluetooth module, and the Bluetooth module sets itself to low-power dissipation standby mode after sending the processed result to the upper computer, utilizing low-speed clock modes and closing down peripheral units to conserve power.

1Use of energy by moving object
If the bluetooth security device enters low-power dissipation standby mode after a preset duration regardless of data reception status, then the device reduces power consumption, but the standby time extension is insufficient
Solution Approach 1:
The patent applies dynamics by making the standby mode entry dynamic rather than static. The security module now adapts its power state based on real-time conditions: it enters low-power dissipation standby mode only when no data is received within the preset duration, but remains in working mode when data is received. This conditional transition optimizes both power consumption and standby time extension by avoiding unnecessary mode switches.
Solution Approach 2:
The patent changes the parameter of power consumption based on operational status. By monitoring whether data is received within the preset duration, the system dynamically adjusts the power consumption parameter - maintaining higher power consumption (working mode) when data processing is needed, and switching to lower power consumption (standby mode) when idle, thereby achieving better overall power management and extended standby time.
2Speed
If the security module remains in working mode during the preset duration regardless of data reception, then the device is ready to process data quickly, but power consumption increases
Solution Approach 1:
The patent implements periodic action by using a preset duration timer to periodically check for data reception. The security module operates in a cycle: it stays in working mode for the preset duration to ensure quick response, then evaluates whether data was received. If no data arrived, it transitions to standby mode. This periodic evaluation mechanism balances response speed and power consumption by not maintaining high-power state indefinitely.
Solution Approach 2:
The patent applies partial action by having the security module maintain working mode only for the necessary preset duration rather than continuously. This partial maintenance of high-performance state is sufficient to capture incoming data while avoiding excessive power consumption that would result from indefinite working mode operation. The module performs just enough work at high power to detect data presence, then transitions to lower power state.

AI summary
A method for implementing low power consumption on standby for a Bluetooth security device. The method comprises: a security module is waked up by a Bluetooth module and configures a working mode as the state of self; a security module determines whether data from the Bluetooth module is received by a fifth preset time; if yes, then executes a corresponding operation on the basis of the received data to produce an operation result, returns the operation result to the Bluetooth module, configures a low power consumption standby mode as the state of self, and waits to be waked up by the Bluetooth module; and if not, then configures the low power consumption standby mode as the state of self, and waits to be waked up by the Bluetooth module. The Bluetooth security device disclosed comprises the security module and the Bluetooth module, where the security module comprises a first configuration module, a first receiving module, a first determining module, an execution module, a first transmitting module, a second configuration module, and a waiting module. The method and the Bluetooth security device in the present invention are of great power saving effects, and the standby time of the Bluetooth security device is extended.
