Multi-event low-power-consumption scheduling method

Abstract

The invention discloses a multi-event low-power-consumption scheduling method, which is based on an MCU with a timer function. The multi-event low-power-consumption scheduling method comprises the following steps: S01, a system is initialized, and an event time table is set; S02, an event timer is started according to the upper application task; S03, the MCU enters a low-power-consumption standbymode; S04, the timer interrupts triggering, and the MCU operates an event scheduling function to judge whether the current interruption is an effective timing event or not through an event time table,and if not, the step S02 is returned, and if so, the step S05 is executed; and S05, task content corresponding to the effective timing event is executed, and the step S03 is returned. Under the condition of a single MCU, the events are sorted, and the recording of the time exceeding the upper limit of the counting of the timer is supported, and the multi-event low-power-consumption scheduling method is specially used for resource-limited low-power-consumption products and has the advantages of being low in cost, low in power consumption, capable of supporting multi-event scheduling and high in 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...
