Infrared grating alarm working mechanism is substantively superior
With the improvement of people's safety awareness, we all know that the home alarm device is an anti-theft device, but I believe that everyone is not familiar with the new type of home-style door and window anti-theft device. Here we will introduce to you the introduction of infrared grating alarm this new type of anti-theft device is how to work, its anti-theft is not really better than ordinary anti-theft device?
Infrared grating alarm This new anti-theft device is also called infrared railings, infrared fences and electronic gratings. It is a kind of anti-theft device using a variety of infrared light. As long as there is an object blocking any two adjacent infrared rays of the infrared grating, the anti-theft system will automatically activate the alarm device. Maybe a friend has to ask: If there is an animal blocking the infrared, it is also not alarming to report it? Animals are usually small in size, do not block two adjacent infrared rays at the same time, and do not trigger its alarm device. Most of these infrared grating alarms are used on balconies, aisles, front doors and windows. When installing infrared gratings in these places, it must be ensured that the infrared emitters must be aligned and parallel. Otherwise, the infrared gratings will be deviated. When an infrared grating is obstructed by any object adjacent to two infrared rays, the power of the transmitting end, the receiving end is artificially destroyed, or the positions of the transmitting end and the receiving end are arbitrarily moved, and an alarm occurs when the direction is changed. It is a very safe, reliable, simple and convenient alarm device. Its safety, stability and practicality are very suitable for family daily security.
Infrared grating working principle
In a grating, a photoemitter emits a row of synchronous parallel infrared beams that are received by the corresponding receiving unit. When an opaque object enters the sensing area. Interrupting the normal reception of one or more infrared beams, the control logic of the raster will automatically issue the emergency stop signal of the target machine.
The launch device is equipped with a light emitting diode (LED). When the timing logic control loop of the grating is switched on Fig.: The safety grating system must be used on machines that can be stopped at any time during the work cycle. It is not suitable for full rotary electric presses and machines. These diodes will send
Infrared veins that are invisible to the naked eye; medium ray. The pulsed rays are sequentially emitted in accordance with a preset specific pulse frequency (LEDs one by one
Bright). The corresponding phototransistor and supporting circuitry in the receiving unit are designed to react only to this particular pulse frequency. These technologies provide greater security and shield possible interference from external light sources. Control logic, user interface and diagnostic indicators can be integrated in a single, stand-alone accessory. It can also be configured on the same rack with the receiving circuitry.
As a kind of the most advanced anti-theft device with beautiful appearance and high sensitivity, infrared grating alarms are popular among the mass consumers. Of course, if you want to make infrared gratings work for us properly, you must ensure that the installation method is correct. Therefore, a friend who wants to use an infrared grating must ask a professional installer to install it. Otherwise, it is only a decoration. Only.
