Disclosed is a hierarchical management method and system for a terminal device. The terminal device comprises at least one control system, and at least one peripheral apparatus, which is connected to the control system. In the method, when a terminal device receives a wake-up signal during dormancy, a control system corresponding to the wake-up signal is woken up, and the control system in a wake-up state grades an operation mode of the control system according to a data load; and according to the operation mode, a peripheral apparatus that needs to perform data processing is woken up.

An energy-saving prediction method for factory electricity consumption and an electronic apparatus are provided. The method includes the following steps. A reference electricity consumption amount in a unit period is predicted based on factory actual operation information in the unit period by using an electricity consumption prediction model. An actual electricity consumption amount in the unit period is acquired. The reference electricity consumption amount and the actual electricity consumption amount are displayed on an electricity consumption reference interface. A function is provided according to a first difference value between the reference electricity consumption amount and the actual electricity consumption amount.

A power down circuitry for a controller of a process control system includes at least one energy storage device configured to store energy for a power down sequence; and at least one data storage device to store control application state data, wherein the power down circuitry is configured to detect power loss and, in response to the detection of power loss, to carry out the power down sequence, wherein the power down sequence comprises obtaining and storing the control application state data in the data storage device, wherein the power down circuitry is further configured to determine at least one reliability indicator for output to an operator of the process control system.

A method for operating integrated circuits of peripherals of a vehicle includes receiving a set of resource requests from one or more applications of the vehicle, wherein a resource request of the set of resource requests at least one resource from one or more peripherals of the set of peripherals of the vehicle. The method also includes storing the set of resource requests, and receiving a resource configuration profile. A setpoint operating state is determined for each peripheral of the set of peripherals of the vehicle depending on the received set of resource requests and the received resource configuration profile. The method further includes controlling the set of peripherals depending on the specified setpoint operating state, such that an actual operating state of a respective peripheral of the set of peripherals corresponds to the specified setpoint operating state of the respective peripheral of the set of peripherals.
