Protective guard

Abstract

The invention provides a protective guard which comprises a protective plate. The protective plate is provided with a solar photovoltaic plate and an infrared sensing plate, a clamping shell is arranged at each of the upper end and the lower end of the protective plate, the protective plate further comprises multiple infrared sensors, each infrared sensor comprises an infrared transmitting head and an infrared receiving head, each infrared transmitting head is electrically connected with an infrared transmitting end control circuit, and each infrared receiving head is electrically connected with an infrared receiving end control circuit; the infrared transmitting heads and the infrared receiving heads are arranged on the infrared sensing plate in a uniformly alternate manner and are in matched connection in one-to-one correspondence, each infrared receiving end control circuit is connected with a wireless communication module which is connected with a PLC (programmable logic controller) control module, and the PLC control module is connected with an alarming module. Invading objects are detected by utilizing infrared rays, so that false alarm probability is lowered, and the protective guard is energy-saving and convenient to mount.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to a protective fence. Background technique [0002] With the advancement of science and technology, the improvement of living standards and people's emphasis on safety, security equipment has been constantly updated and developed rapidly. Security equipment generally includes a trigger device, a monitoring device, and an alarm module. The trigger device is used to detect whether someone has intruded, the network camera is used to understand the surrounding images in real time, and the alarm is used to remind users to pay attention and deter intruders. [0003] Trigger devices in the prior art generally include infrared detection devices, temperature sensing devices, pressure sensing devices, etc., but most of the trigger devices in the prior art cannot judge the size of the intruder, and are prone to false alarms. At the same time, the infrared light protection fence in...

Problems solved by technology

[0003] The trigger devices in the prior art generally include infrared detection devices, temperature sensing devices, pressure sensing devices, etc., but most of the trigger devices in the prior art cannot judge the size of the intruder, which is prone to false alarms

At the same time, the infrared light protection fence in the prior art requires not only the arrangement of data lines, but also the arrangement of power lines. When it is arranged in a large factory area, there will be a disadvantage of difficult wiring.

Moreover, the infrared sensing board works for a long time, consumes a lot of energy, and the cost of use is also high

In addition, the installation operation of the infrared light protection fence in the prior art is relatively cumbersome, and the components are easily damaged during installation.
