DVD navigator based on a vehicle-mounted terminal capable of unloading disc in the sleep state
First Claim
1. A digital versatile disc (DVD) navigator, comprising:
- a menu panel module, configured to generate a first level in response to reception of an unload instruction;
a quick-unload module, configured to acquire and process the first level in a sleep state of the DVD navigator to generate a second level and a pulse signal;
wherein the quick-unload module is controlled according to the second level to quickly unload a disc in the sleep state;
a motor module, configured to control a motor to rotate according to the second level for controlling the quick-unload module to quickly unload the disc in the sleep state;
a DVD module, configured to awaken the DVD navigator after acquiring the pulse signal in the sleep state of the DVD navigator, and to supply power to the motor module;
wherein the menu panel module comprises a first resistor, a button switch and an electrolytic capacitor;
wherein the button switch comprises a first terminal connected to a voltage source via the first resistor, and a second terminal respectively connected to a positive electrode of the electrolytic capacitor and the quick-unload module, and a negative electrode of the electrolytic capacitor is connected to the ground; and
wherein the menu panel module generates the first level when the button switch is closed, and the menu panel module outputs the first level through discharging of the electrolytic capacitor when the button switch is opened.

Abstract
A DVD navigator based on a vehicle-mounted terminal is disclosed. The DVD navigator includes: a menu panel module, configured to generate a first level in response to reception of an unload instruction; and a quick-unload module, configured to acquire the first level in a sleep state of the DVD navigator and process the first level to generate a second level and a pulse signal so as to control the DVD navigator to quickly unload a disc according to the second level in the sleep state. By the aforesaid way, the present disclosure can effectively reduce the unload time of the DVD navigator by controlling the DVD navigator to quickly unload a disc in the sleep state after receiving the unload instruction.
