Problems solved by technology

[0034] Existing technical solutions can only control power consumption by turning on or off each device, and cannot realize a simple step of turning off all devices or turning on all devices, and cannot cooperate with MCU sleep, which is very cumbersome to operate and error-prone

Embodiment Construction

[0044] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] Firstly, based on the RT-Thread device management framework, design the driver for each peripheral, fill in the opening and closing interface of each peripheral driver, realize the power-on or initialization of the device in the opening interface, and realize the power-off and recovery initialization of the device in the closing interface. And register the device driver into the RTOS, such as figure 2 shown.

[0046] Then design a traversal search method according to the RT-Thread device management framework to find the device drivers that have been registered and opened in the system, and call the closing method of the device driver after finding the device driver, and mark the closed device at the same time, such as image 3 shown.

[0047] Th...

Abstract

The invention discloses a low-power-consumption method implemented based on an equipment management framework in an embedded real-time operating system (RT-Thread), and belongs to the technical fieldof computers. According to the method, a low power consumption management strategy based on an RT-Thread equipment management framework is realized; an interface for simply entering a low-power-consumption state is provided for a software layer in the BSP, a method for simply and quickly entering the low-power-consumption state in one step is realized, the MCU enters dormancy after entering the low-power-consumption state to achieve minimum power consumption control, and all the devices are started again after the MCU is awakened from dormancy, so that all the devices enter a working state. Two traversal algorithms are designed in an equipment management framework; wherein one traversal algorithm is used for searching the started devices in the device list and closing and marking the devices, and the other traversal algorithm is used for searching the devices marked in the previous traversal algorithm and opening and removing the marks of the devices, so that low-power-consumption management of all the devices can be realized.
