A Multi-event Low Power Scheduling Method

Abstract

The invention discloses a multi-event low-power scheduling method, which is based on an MCU with a timer function, and includes the following steps: step S01: system initialization, setting an event schedule; step S02: start an event timer according to an upper-layer application task; step S03: The MCU enters the low-power standby mode; Step S04: The timer interrupt is triggered, the MCU runs the event scheduling function, and judges whether the current interrupt is an effective timing event through the event schedule, if not, return to step S02, and if so, execute step S05 ; Step S05: Execute the task content corresponding to the valid timed event, return to step S03. In the case of a single MCU, the present invention realizes sorting and sorting of events, and supports recording the time exceeding the upper limit of the timer count. Event scheduling, high stability.

Description

technical field [0001] The invention relates to the application field of the Internet of Things, in particular to a multi-event low-power scheduling method. Background technique [0002] Many terminal products in the field of the Internet of Things are used in complex and harsh environments (such as water meters, gas meters, smoke detectors, etc.), which require the products to support basic features such as IP65 and above waterproof level, dustproof, etc., so the product shell Generally, it adopts a non-detachable integrated design and is powered by a disposable battery. However, the capacity of disposable batteries is limited, which leads to strict requirements on power consumption of products. In order to realize the maximum value of products, disposable products are required to have a long enough working life (5~10 years), so this requires terminal products to have Excellent low power consumption characteristics. At the same time, in order to achieve mass application i...
