Description
Technical field
The utility model relates to the automatic detection field of position of human body, particularly a kind of position of human body pick-up unit for the control of the room lightings such as classroom.
Background technology
In today that energy problem becomes increasingly conspicuous, energy-saving and emission-reduction have become a theme of socio-economic development.Energy-conservation for room lighting, particularly classroom is energy-conservation, existing a lot of solutions: patent CN201450623U discloses a kind of power saving controller of intelligent classroom lighting in the present prior art, this device is realized being lower than when under national standard and the lamp people being arranged when the classroom illumination degree by human body sensor, optical sensor, single-chip microcomputer, relay and driving circuit, automatically turn on light, when illuminance is up to state standards, automatically turn off the light, realize that the Based Intelligent Control classroom lamp is to reach energy-conservation effect; Patent CN101282605B then discloses a kind of indoor wireless illumination control method based on the Zigbee Sensor Network, by coming testing staff's positional information in porch, room and the some Radio infrared sensors of indoor introducing, and then realize having the people zone to turn on light, the control effect of turning off the light in the no man's land has reached the effect of intelligent power saving.At present, in the control of the room lightings such as classroom, realized preferably to indoor whether the people being arranged by introducing wireless or wired infrared detection module, and the detection of personnel positions, thereby can realize subregional illumination control, reach energy-saving effect.But in actual implementation process, the deployment of infrared detection module relatively is difficult for implementing: if directly use wired layout, complicated from lighting control module to infrared detection module cabling, difficulty of construction is large; If adopt based on the Zigbee wireless mode, then greatly increased the cost of infrared detection module.
The utility model content
The purpose of this utility model is to propose a kind of network-type position of human body pick-up unit, and it has overcome the deficiencies in the prior art, has reached both to dispose easily the purpose of also saving cost.
For achieving the above object, the utility model proposes a kind of position of human body pick-up unit for room lighting control, comprise main control module and detection module, both are with the networking of connecting of unibus mode; Main control module comprises main control unit MCU, Zigbee wireless transmission unit, single bus interface unit and infrared detection unit; Wherein, main control unit MCU utilizes the single bus interface unit to gather the detected state of infrared detection unit, simultaneously by the data communication of Zigbee wireless transmission unit realization with other unit, the Zigbee wireless transmission unit realizes the communication of main control unit MCU and other unit with the Zigbee wireless mode, whether infrared detection unit has human body to exist for detection of its induction region, and communicating by letter between main control module and the detection module realized in the single bus interface unit; Detection module comprises single bus interface unit and infrared detection unit, and wherein whether infrared detection unit has human body to exist for detection of its induction region, and communicating by letter between main control module and the detection module realized in the single bus interface unit.
Further, main control unit MCU utilizes the single bus interface unit regularly to detect the state of its infrared detection unit, when its surveyed area has personnel to occur, will present high level state, otherwise be low level state.What main control unit MCU regularly detected is set to 5 ~ 10 seconds usually.
The position of human body pick-up unit that is used for room lighting control that the utility model proposes, a main control module can carry out the unibus networking with interior detection module with 10.
In actual deployment, detected zone can be divided into several according to lamp control needs and detect subregion, a detection module is installed at ceiling region center corresponding to every sub regions, or main control module, and with detection module and main control module with the networking of connecting of unibus mode.Main control module utilizes the detected state of the detection module of unibus periodic polling and its networking, and its state is passed through the Zigbee protocol report to main control unit MCU.
The beneficial effects of the utility model are, and are convenient and simplified the deployment of infrared human body detection module by introducing wireless Zigbee and unibus two-level network mode, reduced implementation cost.
Description of drawings
Fig. 1 is the utility model-be used for building-block of logic of the position of human body pick-up unit of room lighting control.
Fig. 2 is the utility model-be used for deployment examples synoptic diagram of the position of human body pick-up unit of room lighting control.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, pick-up unit of the present utility model comprises main control module and detection module, and main control module comprises that main control unit MCU, Zigbee wireless transmission unit, single bus interface unit, infrared detection unit form; The Zigbee wireless transmission unit realizes the communication of main control unit MCU and other unit with the Zigbee wireless mode, whether infrared detection unit has human body to exist for detection of its induction region, and communicating by letter between main control module and the detection module realized in the single bus interface unit; Main control unit MCU is used for regularly detecting the state of its infrared detection unit, when its surveyed area has personnel to occur, will present high level state, otherwise be low level state; Main control unit MCU regularly sends the status poll instruction to each detection module with its networking simultaneously, to obtain the detected state of each detection module, the main control unit MCU detected state that it is collected sends by the Zigbee wireless transmission unit on this basis.The assay intervals here can be set to 5 ~ 10 seconds usually.
Detection module comprises single bus interface unit and infrared detection unit, and whether infrared detection unit has human body to exist for detection of its induction region, and communicating by letter between main control module and the detection module realized in the single bus interface unit.The detected state of infrared detection unit is directly reflected in the single bus interface unit, and when the single bus interface unit receives the status poll instruction its present state is fed back to main control module.
Further, in actual deployment, a main control module can carry out the unibus networking with interior detection module with 10, and main control module is the main control end of whole Monobus network, also can carry out human detection to the own zone of detecting.Fig. 2 has described the zone division in a larger area classroom and the deployment scenario of position of human body pick-up unit.
Therefore, the utility model is by introducing two-level network, i.e. the mode that combines of wireless Zigbee and unibus mode effectively reduces the cost of whole human body detection device, also simplifies and made things convenient for the practice of construction deployment.
