The invention relates to a method for controlling energy equipment according to regional population distribution in a building, belonging to the technical field of energy conservation and fire-fighting evacuation of the buildings. In the method disclosed by the invention, a staff access detection device, a human body detection device and a region controller are used. According to the method disclosed by the invention, on one hand, when the human body detection device in a region detects that no people occurs in the region, the number of the people in the region is set to be zero, and on the other hand, by performing region division on the building and estimating the detention time of staff in the region according to the regional functional characteristics, the correction of the deviation of the number of the people in the region can be realized according to the comparison between the region access time of the staff, which is detected by the access detection device, and the detention time of the staff in the region. According to the regional population distribution in the building, which is obtained by the method, electric equipment, fire-fighting evacuation equipment and the like in the region can be controlled through the controller, so that the energy-saving effect of the building and the evacuation efficiency when an emergency occurs are improved and the safety of the staff in the building is ensured.
Description
Technical field
The present invention relates to a kind of method that distributes energy device is controlled according to buildings inner region number, belong to building energy conservation and fire-fighting evacuation technical field.
Background technology
Along with intelligent building constantly develops, building energy conservation and security against fire become very important in an architectural development process importance.Traditional building energy conservation and fire-fighting evacuation are based upon in the initial stage design of building, in servicely in the building in later stage exist numerous unreasonable and drawbacks, are a kind of static systems such as traditional fire-fighting evacuation system; Can not the interior number of real-time perception building distribute; When disaster takes place, can not be effectively, dynamically the personnel in the building are evacuated, maybe be because some area people be too much; Guiding takes place crowded, has caused some unnecessary loss.Therefore the building energy conservation and the fire-fighting evacuation system entails that are based upon on the building inner region number distributed basis have higher efficient and meaning.
Yet the regional number in the present building estimates but do not have a kind of otherwise effective technique and method.The technology and the method that at present in the building, are applied to locate mainly contain, wireless radiofrequency technology, video statistics, infrared perception etc., however these systems but exist numerous problems:
Based on the positioning system of radiofrequency signal, need the people to wear positioning label like gate control system, such as for the passive radio frequency card, need enter and swipe the card etc., caused some inconvenience for people's normal behaviour; Positioning system based on rf wireless signal intensity (RSSI) also needs the people to wear positioning label, though the operation of swiping the card of need not entering, because the multipath effect that wireless signal exists in building etc., its bearing accuracy is not high; Video positioning system based on camera exists the Video processing difficulty big on the one hand, and the problem that the number evaluated error is big also can expose people's privacy on the other hand, makes people be reluctant to accept such system.The applying date is 2011.04.22, and publication number is the patent of invention " based on the passenger flow statistical method and the system of machine vision " of CN102184409A; The applying date is 2010.11.23, and publication number is the patent of invention " a kind of anti-AB door access management system of following " of CN102063750A; The applying date is 2011.03.03, and publication number is that the utility model patent " a kind of passenger flow information statistics equipment " of CN202013603U waits these patent systems to be this type systematic, all not can solve top problem.
The applying date is 2011.01.18; Publication number is the utility model patent " intelligent number sniffer " of CN201946030U; The applying date is 2009.08.27; Publication number is to have proposed in the utility model patent patents such as " a kind of intelligent power saving and demographics equipment " of CN201689298U based on infrared method to injection device testing staff turnover, has solved the normal behaviour of giving the people problem with invasion of privacy of making troubles to a certain extent.Yet the system of this type but exists another important problem; The system location can not guarantee that 100% is accurate, and is interfered easily, and in a single day deviation appears in system; Will long-term existence; The growth that the long-term operation of system must bring cumulative errors finally makes its number that comes out lose meaning, thereby has also just lost the directive significance for building energy conservation and fire-fighting evacuation.
Summary of the invention
The objective of the invention is to propose a kind of method that distributes energy device is controlled according to buildings inner region number; Personnel statistical method in the existing buildings is improved; Understanding the construction area personnel more accurately distributes; So that, Architectural Equipment is regulated and control according to personnel's distribution situation, energy savings and raising security.
