Description

Hierarchical dormancy distributed electronic control system, control method and product Technical Field The application relates to the field of automatic control power management, in particular to a distributed electronic control system, a control method and a product for hierarchical dormancy. Background The electric actuator uses electric power as a driving source, receives a control signal and converts the control signal into mechanical motion, and is widely applied to various industrial automation control fields. In the application of the electric actuator, it is sometimes necessary to implement the electric actuator in an application scenario in which a cable power supply condition is lacking. For example, the underground valve of municipal pipe network lacks commercial power, the cost of laying cables is high and difficult, the field industrial facilities such as oil-gas field, long-distance pipeline and the like are remote and cannot be connected to the power grid, the safety requirement is extremely high, the isolation between the internal power grid and the external power grid is required, the positions of distributed field sites such as environmental protection monitoring, agricultural irrigation and the like are dispersed, and the power supply infrastructure is lost. Under the scene that the power can not be supplied through the cable connection electric wire netting, the battery power supply can be adopted generally, and the electric energy supply strategy of cooperation distributed generation for battery charging under the partial circumstances satisfies the power supply demand of electric actuator. Due to the limitation of battery capacity, in order to ensure the endurance requirement of the electric actuator system, the energy consumption of the electric actuator needs to be reduced as much as possible. The electric actuator is in a standby state for most of the time, the real actual action time is short, and the battery energy is wasted greatly due to the excessively high standby power consumption, so that the electric actuator needs to go into dormancy during standby, the service life of the battery is prolonged, and whether the equipment can realize long-term, stable and reliable unattended operation is directly determined. The power consumption of the electric actuator is related to the degree of dormancy. The lower the dormancy degree is, the faster the awakening response speed is, but the energy-saving effect is not ideal, and the method is suitable for the electric actuator which is started intermittently more frequently, and the deeper the dormancy degree is, the better the energy-saving effect is, but the longer the time required for awakening and the more the energy is required. Therefore, to achieve the desired energy saving effect, it is necessary to configure the electric actuator with a sleep mechanism conforming to the operation state thereof. The existing dormancy mechanism of the electric actuator has single dormancy mode, so that the balance of the energy-saving effect and the awakening response time of the electric actuator is difficult to coordinate, and the dormancy energy-saving effect is influenced.
