Abstract
The invention relates to wireless network video equipment, in particular to a power consumption management method of a network camera, which comprises the following steps: a power consumption management system of the network camera are divided into four layers: a bottom layer, an OS (Operating System) layer, a transport layer and an application layer, wherein the bottom layer adopts a multi-core processor, and comprises an MCU (Microprogrammed Control Unit) and a coder; dynamic power supply management is set in the OS layer so that different power supply levels are set for different tasks; the transport layer uses a 2.4GRF transport protocol; a normal browsing mode and a sleep energy-saving mode are arranged in the application layer; according to needs, the power supply management is carried out to hardware of the bottom layer through an application layer interface and an OS layer interface, so that the frequency of the MCU is reduced, the MCU is suspended into a storage, and closes external equipment to stop working, the coder is set into a sleep state; and the code can be waken to normally work by stopping SPI (Single Program Initiation). The method can greatly reduce the consumption of the network camera, realizes long-time online state, can meet the high-level requirements in military and the like; and the wireless design is adopted, so that the wiring trouble is free.
Description
Technical field
The present invention relates to a kind of energy-conservation power consumption management method of wireless video collecting device, particularly a kind of IP Camera.
Background technology
Wireless sensing product in the Internet of Things can be divided into two classes according to application at present: the one, and the wireless data sensing product of RFID type; The 2nd, the IP video product.The first kind is mainly used in logistic industry, though power consumption is little, data quantity transmitted is limited.The second class IP video equipment is the typical case with the web camera, has run into technical bottleneck when wireless penetration, the power consumption that is Video processing, transmission is too high, general power consumption about 2W, with present battery technology, best wireless product also can only support 3 hours online; If add power amplifier, power will further be promoted to 7W, just can't realize moving and use, so general web camera product all adopts external power supply, poor mobility can't be applied to the application scenario that military, public security etc. needs the online equipment of long-time mobile video.
Summary of the invention
Heightened awareness based on to existing IP video product, particularly web camera the present invention seeks to: at the power management of radio transmitting method and application system, invent a kind of energy consumption management method of web camera of low-power consumption.
For reaching above-mentioned purpose, the technological means that the present invention adopts is: the managing power consumption system configuration of whole web camera is considered as four layers: bottom, OS layer, transport layer and application layer.Bottom adopts polycaryon processor, wherein comprises a MCU and an encoder; Arrange dynamic power management in the OS layer, different power level is set at different tasks; Transport layer is used 2.4G RF host-host protocol; In application layer, normal browsing pattern and sleep energy saver mode are set, as required, by application layer and OS layer interface, bottom hardware is carried out power management, reduce the frequency of MCU, suspend in the memory, and close peripheral hardware, quit work, and encoder is made as sleep state; The operate as normal of waking up of this encoder interrupts realizing with SPI.
Preferred L CU uses arm processor.After the MCU frequency reducing, it is RAM that system hangs up the memory that stores.
Method of the present invention, the whole adjustment on hardware, the software configuration, can reduce power consumption significantly, in working order down as long as 700mw, be that the power-on time of lithium battery of 1/3, one 1800 mah of similar products at home and abroad can reach 10 hours, integral device weight is less than 1 jin, if use the double copies battery, can 24 hours power supply continuously, solved mobile individual soldier system Field Operational problem in military first.And the equipment of making under this method thought can arbitrarily be placed on any place in the wireless coverage, need not to consider power supply, wiring problem.
Description of drawings
Fig. 1, the system structure model of use the inventive method.
Fig. 2, the workflow diagram of the inventive method.
Embodiment
Be clearer explanation specific implementation of the present invention, as follows in conjunction with the accompanying drawings:
System structure model of the present invention has bottom, OS layer, transport layer and application layer as shown in Figure 1.Bottom is selected multi-core CPU system (Multi Core CPU), wherein comprises a MCU and an encoder (Codec DSP), also has general CPU parts such as RAM memory; Need at different task processing, improve the service efficiency of whole CPU.Because the fail safe of WiFi and big power problems, transport layer of the present invention adopts the wireless privately owned host-host protocol of 2.4G RF, has not only reduced power consumption, and since proprietary protocol simplify independence, less demanding to microprocessor, thus reduce overall power.In addition, on the OS layer, arrange dynamic power management, adopt the switching of multiple mode of operation on the application layer, use with the lowest power consumption that reaches total system.Concrete multiple mode of operation includes normal mode of operation and energy-conservation sleep pattern at least, and the normal mode of operation power consumption is normal, low power operation under the energy-conservation sleep pattern.
Concrete work the time, flow process as shown in Figure 2: to set normal mode of operation in the application layer and two kinds of patterns of sleep pattern are example, normal mode of operation is the video tour pattern, carries out work such as video acquisition, coding and wireless transmission, consumes normal power consumption; Sleep pattern is energy-conservation managing power consumption pattern.Specifically: arrange SPI to interrupt carrying out the judgement of mode switch, after for example not browsing 30 seconds, equipment enters sleep pattern automatically, the collection of stop tone video data, encoder (Codec DSP) is no longer encoded, and also enters sleep state, simultaneously the MCU(ARM processor) carry out frequency reducing, operate in low frequency, thereby reduced the overall power of system; When needs wake up, by the judgement that SPI interrupts, switch to normal video tour pattern and recover operate as normal, consume normal power consumption.
Claims (3)
