Description
Technical field
The present invention is related to energy-saving management system and method thereof, espespecially a kind of energy conserving system based on wireless signal strength and method.
Background technology
A lot of electric equipment in family, may often be such that people in just open use, and when people to leave scene or go out, originally this turn off the power switch of whipping one by one, use and reach energy saving and safe purpose. But, for busy modern, it is possible to neglect these little tricks because of hasty; For the elder person in family, it is possible to because of inconvenience in the action, and have actual difficulty; Teenager is likely to because without this custom, and allows the saving energy become slogan, to such an extent as to the so simple action of powered-down conveniently, it appears that neither be easy for reaching. And the problem that it is derived, the thing that sinks money in vain is little, if causing in family the safety problems such as fire alarm, probably will make us lifelong regret.
In order to achieve the above object, suggesting that of intuition, as long as we differentiate whether this space has personnel, use the basis for estimation reaching whether be further turned off power supply. Also therefore, we need the technology with detecting personnel, known conventional personnel sensing technology, it is exactly utilize infrared ray (Infrared) to detect, it can divide into active infrared twin-beaninfraredsensor (sensor itself can be launched infrared light beam detecting object and move), with passive infrared PIR (sensor itself will not launch infrared light beam, but leans on the thermal source mobile trigger sensor of object).
Active infrared great majority are all 2 (in pairs) and use together, one for launching infrared light beam (Transmitter), another is receiving infrared-ray light beam (Receiver), is primarily adapted for use in the point-to-point air line distance of indoor or outdoors and uses; The passive infrared mobile personnel sensing application being then applicable to indoor closing space. Generally speaking, the more passive infrared PIR of cost of active infrared is high, because itself continuing to launch infrared light beam, therefore it is little to be disturbed wrong report chance, relative, its scope that can detect is only limitted to point-to-point air line distance, often contains greatly reconnaissance range not as what passive infrared PIR had a whole space; But PIR is mainly by the thermal source mobile trigger sensor of object, detecting result erroneous judgement will be caused when personnel's transfixion.
According to TaiWan, China patent: M478294-infrared ray lavatory light switch, whether this patent is reach lamp source energy-conservation, therefore utilizes an infrared ray sensor, have object to pass through this sensing region in order to detect; Its use technology is PIR infrared technology, though its cost is low, but the scope monitored is relatively small; The equipment that can save energy is less, and, when the human body sensed is static do not move time, infrared sensing equipment will be considered to personnel and has been moved off and turn off electric light, and so misoperation will result in the inconvenience in use.
And recent universal along with IPCam (networkcamera, web camera), also someone utilizes the technology of image identification, reaches the effect that space personnel judge; According to TaiWan, China patent: the control method of I386769-imaging monitoring indoor environment state and system, this patent passes through the environmental condition change such as state such as number, distribution scenario and crowd's trend that imaging monitoring is indoor, and can automatically in response to the air-conditioning and the illumination condition that adjust indoor each interval. This utilization captures the monitoring means of real-time imaging, need the hardware storage equipment of high power capacity for the relevant audio and video information of record, therefore more equipment and cost must be expended; Especially, the every act and every move of monitor area personnel videoed completely, notes down, and even stored image likely outflows or suffers improper use, by the personnel's privacy in serious harm monitor area.
As known from the above, it is necessary to the energy-saving management system of a kind of novelty, to assist user properly to solve existing problem.
Summary of the invention
The invention discloses a kind of energy conserving system based on wireless signal strength and method, reach space personnel detecting, with further automatic switch power and setting electric equipment state, reach to utilize existing wireless terminal device, under the cost not increasing extra sensing devices, get final product the correct purpose reaching energy saving and safety and effect.
Constituted owing to human body percent 70 is above water, therefore, human body close to usually affecting and disturb wireless signal strength. This patent uses a plurality of wireless terminal devices, is set by user in a specific field domain, the electric equipment of relevant wireless terminal device institute keyholed back plate, if should be automatically switched off associated electrical appliance equipment when personnel leave. A plurality of wireless terminal devices will learn in specific field domain voluntarily, the result of the wireless signal strength when nobody haunts, to differentiate this space wireless signal strength in time haunting without personnel. Afterwards, when personnel leave field domain or during not in use by environment, system then automatically according to the demand of user, closes the power supply of associated electrical appliance equipment, is really achieved the purpose of energy saving and Electrical Safety at home.
The present invention provides a kind of energy conserving system based on wireless signal strength, comprises background apparatus, service controller and a plurality of wireless terminal device and is linked.
