Abstract

The embodiment of the invention provides a system and method for controlling power-on of a main control module, the system comprises a clock chip, an external circuit and the main control module, the clock chip is connected with the external circuit, and the clock chip is used for transmitting a trigger signal to the external circuit when the trigger time is up; the external circuit is connected with the main control module, and the external circuit is used for controlling the main control module to be powered on through the field effect transistor when receiving the trigger signal. According to the invention, the problem of high static power consumption of the vehicle-mounted equipment is solved, and the effect of realizing the automatic startup and shutdown function of the vehicle-mounted equipment with extremely low static power consumption is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, relate to a system and method for controlling power-on of a main control module. Background technique [0002] With the development of connected car technology, a large number of electronic devices are used in vehicle-mounted equipment, such as driving recorders for small passenger cars, streaming media rearview mirrors, and vehicle-mounted monitoring hosts for commercial vehicles. The requirements for static power consumption are relatively high, and in some scenarios, it is necessary to switch on and off the device regularly to realize real-time monitoring of the vehicle condition and the surrounding environment of the vehicle under unattended conditions. [0003] The existing low-power automatic startup method is to control the power-on of the main control module through the MCU system. The MCU determines the startup time according to the time of th...
