Problems solved by technology

[0005] Most of the traditional pyroelectric sensor monitors are equipped with Fresnel lenses. It has a shortcoming that it is only sensitive to people moving radially along the Fresnel lens, but relatively slow to people moving perpendicular to the Fresnel lens. This may cause unrelated personnel to cause monitoring busy points when

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see Figure 1 to Figure 7 , a remote pyroelectric induction monitor, comprising a casing 1, on which a trigger 2, an LED light, and a Fresnel lens 13 are arranged respectively, and there are two Fresnel lenses 13 on the left and right. When someone enters the early warning range of the monitor, the infrared rays emitted by the person pass through the Fresnel lens 13 and enter the monitor to be sensed by the detector and send a radio frequency signal to the external radio frequency transmitter through the built-in radio frequency transmitter (not shown in the figure). A WIFI host (not shown in the figure), the WIFI host is transcoded and forwarded to the mobile terminal.

[0019] Described Fresnel lens 13 is fixed on the support frame 11, and the shape of described support frame 11 is similar to spectacle frame, and there is a connecting bridg...

Abstract

The invention discloses a remote heat-release electric sensing monitor which comprises an LED lamp, two Fresnel lenses and a trigger. The two Fresnel lenses form a certain angle, even a person walks towards the monitor, an infrared signal can be also sensed, keys on the trigger can be moved, and an alarm can be eliminated by correctly pressing down a corresponding key within specified time. The problem that a traditional heat-release electric sensing monitor is insensitive to the person forwards close to the monitor is effectively solved.

Description

technical field [0001] The invention relates to a monitoring and alarming device, in particular to a remote pyroelectric induction monitor. Background technique [0002] Houses, factories, warehouses, waterworks and other places are very sensitive to the entry of personnel. For example, places where important items are stored are generally protected by security doors, security windows, and walls, but it is still difficult to avoid the entry of personnel, so a The device that can monitor the entry and exit of people, the pyroelectric sensor monitor was born. [0003] The pyroelectric induction monitor is mainly made of a material with a high pyroelectric coefficient, such as lead zirconate titanate ceramics, lithium tantalate, and triglyceride titanium sulfate. One or two detection elements are installed in each detector, and the two detection elements are connected in series with reverse polarity to suppress the interference caused by the rise of its own temperature. The ...
