The novel human body sensor has the advantages of high sensitivity, far sensing distance, convenient design and installation and ability of solving the shortcomings of blocking type sensing; in addition, the use of the Fresnel lens can increase the angle of the human body sensing detection region; the selectivity of a probe of the sensor to the infrared wavelength can solve the mis-sensing caused by other obstacles, thereby realizing the real human body sensing; and the passive receiving way of infrared rays is adopted for transferring the sensing result to an MCU of the comprehensive indicating device of the switch cabinet by the level way, thereby effectively saving resources of circuits and software design.
Description
Technical field
The utility model relates to the comprehensive indicating device of a kind of power switch cabinet, relates in particular to the novel human inductor that is used for the comprehensive indicating device of switch cubicle.
Background technology
The comprehensive indicating device of existing switch cubicle is when realizing human body induction function on the market, the mode of---shelter reflection---infrared ray reception of generally adopting infrared, as shown in Figure 1.
This mode has following shortcoming:
(1) consider the on off state indicating device when actual installation, general position is higher, and the method realizes that infrared time receiving angle is less, causes the people to walk close to device easily, and device can't perception.That is to say that the actual induction zone is less.
(2) owing to adopt shielding mode, can be thought by mistake be to have the people approaching by device at any shelter in actual induction district, and take corresponding operation.Specifically, if the place ahead of on off state indicator has objects such as miscellaneous equipment or wall to exist, it is close that device can have been sensed " people " always so, and this moment, human body sensing promptly lost due function.That is to say that the human body sensing that this method realizes is actually " shelter induction ", lacks selectivity.
(3) from the circuit angle, the emission infrared ray that this method need not stopped has increased the design power consumption of Design of device power supply, also needs more resource to be used to realize this function on the software, has increased the cost of product.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, and a kind of simple in structure, novel human inductor that high-efficiency reliable is used for the comprehensive indicating device of switch cubicle is provided.
The purpose of this utility model can be achieved through the following technical solutions: the novel human inductor that is used for the comprehensive indicating device of switch cubicle, it is characterized in that, this inductor comprises Fresnel Lenses, pyroelectric infrared-sensing head, handles and amplify chip, described Fresnel Lenses is embedded on the device panel of the comprehensive indicating device of switch cubicle, described pyroelectric infrared-sensing head is located in the comprehensive indicating device of switch cubicle, the rear of Fresnel Lenses, described processing are amplified chip and are connected with the pyroelectric infrared-sensing head.
This inductor also comprises power supply, and this power supply amplifies chip with pyroelectric infrared-sensing head, processing respectively and is connected.
Described pyroelectric infrared-sensing head is to respond to the inductive head of infrared variation of 7-14 mum wavelength on every side.
Described processing is amplified chip and is connected with the MCU of the comprehensive indicating device of switch cubicle.
Compared with prior art, the utility model has the advantages that to have highly sensitively, distance of reaction is far away, and design and installation is convenient, can also effectively solve the shortcoming of blocking the formula induction; The use of Fresnel Lenses has in addition increased the angle of human body sensing detecting area; Sensor probe to the selectivity of infrared wavelength solved false sense that other shelter causes should, realized real human body sensing; Adopt the infrared mode of passive reception, circuit low in energy consumption will be responded to the MCU that the result passes to the comprehensive indicating device of switch cubicle in the level mode, save the resource of circuit and software design effectively.
Description of drawings
Fig. 1 is the synoptic diagram of prior art;
Fig. 2 is the synoptic diagram that the utility model is used for the novel human inductor of the comprehensive indicating device of switch cubicle.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
The utility model is used for the various indoor switch cubicles of 3kV-35kV, detect and show the duty of equipment such as isolating switch, on-load switch, disconnector, grounding switch in the high pressure set of equipments, and in conjunction with an electrical principle, dynamically, the duty of display circuit intuitively.Device also has functions such as electrification in high voltage shows, the Temperature and Humidity Control of automatic heating and dehumidification, human body sensing.
Human body sensing is that can to have perceived the people in the finger device course of work approaching, and do the closure backlight, that pass through relay tip of opening LCDs automatically and control corresponding operatings such as interior light unlatching and voice suggestion, as " this cabinet is charged, please notes safety! "; When the people away from switch cubicle after a period of time, device can be closed LCD backlight and illumination automatically.
As shown in Figure 2, the novel human inductor that is used for the comprehensive indicating device of switch cubicle is a main devices with pyroelectric infrared-sensing head and processing amplification chip, is equipped with power supply and some simple peripheral circuits, finishes the induction to human body.The pyroelectric infrared-sensing head can be responded to infrared variation of 7-14 mum wavelength on every side, and this variation is passed to special chip, through processing and amplifying, and output high level (or low level).The MCU of the comprehensive indicating device of switch cubicle regularly detects this level, can whether approaching the or process device of people be arranged perception.In addition, in the place ahead of pyroelectric infrared sensor, Fresnel Lenses (Fresnel lens) has been installed.These lens have two effects, the one, focussing force, be about to heat and release infrared signal refraction (reflection) on probe, reach increase actual induction zone by the incident angle that increases receiving infrared-ray, the 2nd, search coverage is divided into several area pellucidas and dark space, make the mobile human body that enters search coverage release infrared signal on probe with the heat that the form of temperature variation change.
This human body sensing is highly sensitive except that having, and distance of reaction is far away, outside design and installation is convenient, can effectively solve the above-mentioned shortcoming of blocking the formula induction.The use of Fresnel Lenses has increased the angle of human body sensing detecting area; Sensor probe to the selectivity of infrared wavelength solved false sense that other shelter causes should, realized real human body sensing; Adopt the infrared mode of passive reception, circuit low in energy consumption will be responded to the result in the level mode and pass to MCU, save the resource of circuit and software design effectively.
