[0006] Preferably, the mobile DR power management module is connected to the tablet computer through a current detection unit and / or a 232 communication unit to detect the status of the tablet computer.
[0007] Preferably, the control of the mobile DR power management module includes power-on control and power-off control: when the mobile DR power management module receives a power-on signal, it controls the battery module to connect the battery power supply, and after self-checking, it supplies power to the tablet computer power management module; when the mobile DR power management module receives a power-off signal, it detects the status of the tablet computer: when the tablet computer is in the working state, it controls the tablet computer to power off and cuts off the power supply of the whole machine device; when the tablet computer is in the power-off state, it cuts off the power supply of the whole machine device.
[0008] Preferably, the power-on signal is triggered by manually controlling the power-on button; the power-off signal includes an active power-off signal and a passive power-off signal. The active power-off signal is triggered by manually controlling the power-off button, and the passive power-off signal is triggered by the battery module in a low battery state.
[0009] Preferably, the battery module triggers the passive power-off signal when the battery level ≤ 5%.
[0010] Preferably, the battery module is connected to the mobile DR power management module through a 485 communication unit.
[0011] Compared with the prior art, the present utility model has the following advantages: It controls respectively when the whole machine device is turned on and off, avoiding the impact caused by directly powering on the tablet computer and the loss of internal data of the tablet computer due to sudden power-off. It controls the battery module, thereby protecting the battery life and extending the usage time of the lithium battery. Description of the Drawings
