Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment provides a battery power saving method, which sets three states of low speed/normal/high speed and controls the setting of gears in a manual mode and an automatic mode; if manual setting is carried out, the debugging key switches the low speed/normal/medium speed three states, and simultaneously the set state is recorded in the memory; if the automatic setting is carried out, the working state of each device is set, information is sent to the devices, the state of each device is further changed, and meanwhile the duration of the unit communication period is changed.
In this embodiment, the battery-powered device needs to operate in a low-speed mode for as long as possible, and power consumption control is performed in a timeout self-recovery manner (the low-speed mode may affect the interaction efficiency of information, and therefore the device may need to operate in a high-speed or medium-speed mode due to functional requirements to accelerate battery loss), and a duration for each device to automatically recover to the low-speed mode may be set at a platform or a controller.
The embodiment performs information interaction in the whole network, prolongs the service life of the battery, and reduces power consumption by increasing the battery capacity or selecting low-power-consumption devices as far as possible in the aspect of hardware on the premise of presetting design indexes.
Example 2
In the practical research level, the fire-fighting internet of things equipment generally selects a disposable battery as a power supply to analyze the capacity of the battery, so that the service life of the battery is prolonged as much as possible. The technical solution needs to be based on a full understanding of the characteristics of the battery in order to select the most suitable battery solution.
According to the embodiment, the influence of the communication technology on battery endurance is researched, the fire-fighting Internet of things system is used in a building, the system adopts a reasonable network topology structure, and the farther communication distance is the most direct and effective scheme for improving the network value.
With the development and diversification of communication technologies, a wide area network communication technology with low power consumption is becoming a mainstream solution. However, as analyzed from wireless communication technologies, long-distance communication generally requires more energy consumption.
In this embodiment, for a fire-fighting internet of things system, a comprehensive scene and function selection communication technology is required, a low-power consumption long-distance wide area network (LPWAN) covering a range of several kilometers can be constructed by using an LoRa technology, and a low-power consumption Bluetooth (BLE) technology is suitable for short-distance communication, but the consumed electric quantity is greatly reduced.
In order to save the capacity of the battery to the maximum extent, the device should reduce the communication frequency and drive the communication circuit when enough data values are accumulated for transmission.
The influence of battery endurance of the internet of things system structure is researched, the battery-powered internet of things equipment is in a network, and the control management of the power consumption of the equipment is determined by the interaction frequency of communication, the stability of the network and the like. The common network topology structures are shown in fig. 1 as a star network, a tree network, and a Mesh network.
In this embodiment, on the level of a single node, state switching in the network needs to be considered. The LoRaWAN network topology and the NB-IoT network topology commonly used in the LPWAN are both typical star network topologies. The method is characterized in that the terminal equipment communicates with a gateway or a base station. In addition to the transmit and receive windows, the time terminal is in a sleep state.
The architecture of the embodiment is a typical topology structure of a low-power-consumption network topology. The routing nodes of the tree network adopting the static routing and the Mesh network adopting the dynamic routing bear the functions of data management and relay, so the equipment power consumption is higher than that of terminal equipment, but the star network adopts point-to-point communication, is restricted in a complex building or the communication distance thereof, and cannot be used in a large scale and a large range.
In order to eliminate the uncertainty of the power consumption of the routing equipment and consider the complexity of the building, the tree network adopting the static routing is combined with the remote communication technology, so that the solution of the fire-fighting internet of things is suitable.

In the embodiment, the debugging button is pressed for a long time, the equipment is recovered to the low-speed mode, and meanwhile, the indicator lamp continuously flashes to prompt that the default low-speed mode is recovered. Each change of the working state of the device requires forwarding the state information to the platform or the controller for recording through the transport network device layer.
The automatic synchronization mode of the system of this embodiment is implemented by setting the operating state of each device in the platform or the controller, and when the battery-powered device arrives in the next communication cycle, transmitting the set state information to the device through the transmission network device.
