Technical Field

The invention relates to the field of security equipment, in particular to a cooperative infrared fence intrusion detector.

Background

An infrared fence intrusion detector (hereinafter referred to as an infrared fence) is a safety precaution product which is formed by matching a main rod and a slave rod, wherein the transmission and reception of infrared rays on the main rod correspond to the reception and transmission of infrared rays on the slave rod one by one, and once a human body or an object passes between the main rod and the slave rod, the infrared rays are intercepted and transmitted, and then an alarm is sent out. In the practical application field of the security system, the infrared fence product is mostly applied to perimeter protection, namely, arranged on the outermost layer of a security area, such as an enclosure, a garden, a doorway, a window and the like. The existing infrared fences are mainly divided into two types of products, namely correlation products and mutual correlation products, and attention needs to be paid to the following products: for convenience of description, the infrared barrier of the present invention is illustrated herein as being specifically directed to an infrared barrier of the reflective type, and the present invention is also applicable to infrared barriers of the reflective type.

Although the infrared barrier product has the advantage of a far guard distance between the master and slave bars, the infrared barrier always has a limit distance, for example, when the guard linear distance exceeds the transceiving distance of a single group of gratings, usually, one thinks of one group (A) along the linear direction of the guard area_{On the upper part}、A_From) Are connected in one group (B)_{On the upper part}、B_From) Several sets of gratings are installed to solve this problem. Specifically, the method comprises the following steps: suppose a defense area A_{On the upper part}Point to B_FromThe linear distance of the points is 80 meters, the reliable protection distance of the single group of gratings is 50 meters, and then 2 groups of gratings need to be relayed, so that the protection area can be completely sealed. According to the design intention, the corresponding defense scheme is as follows: a of the A-group grating_{On the upper part}Rod and A_FromThe rods are paired and are responsible for the precaution work of the 0-50 m section; and B of the B group of gratings_{On the upper part}Rod and B_FromThe rods are paired and are responsible for the precaution work of the section of 50-80 meters. This scheme will A_{On the upper part}、A_From；B_{On the upper part}、B_FromArranged in a row, and looks like the cumulative distance A of 2 groups of infrared barriers_{On the upper part}B_FromDistances of > 80 meters meet the distance requirement, but in practice these 2 sets of gratings are not working. The reason is that: A. two B groups are the mutual-emission infrared fences, although the nominal reliable protection distance of the grating is 50 meters, in order to ensure that the grating can normally work in rainy days and the like, the actual infrared receiving and transmitting distance of the grating is far more than 80 meters, and therefore the interference problem is brought: namely A_{On the upper part}Emitted infrared light, A at 50 m_FromCan receive B far at 80 m_FromCan also receive, then B_FromWill receive A at the same time_{On the upper part}And B_{On the upper part}Two signals cause that the defense arrangement scheme can not work normally due to the same-frequency mutual interference of two adjacent pairs of gratings, and false alarm is generated. In addition, besides the mutual-emission infrared fence, when the mutual-emission infrared fence is improperly arranged and influenced by factors such as refraction, the mutual-emission infrared fence also has similar interference conditions to cause false alarm.

In actual combat, under the conditions of terrain limitation, need to increase warning distance and the like, more than 2 groups of gratings need to be arranged in close proximity to each other during installation, and in view of the fact that adjacent gratings can interfere with each other to cause false alarm, a new invention is needed to overcome the problem, so that the urgent demand of the market on the high-performance infrared fence can be better met.

Disclosure of Invention

The invention aims to provide a cooperative infrared fence which is used for solving the problem of mutual interference and misinformation generated when the gratings are installed closely adjacent to each other. In practical application, the close-proximity multi-pair grating mounting mode comprises the following steps: in order to avoid the mutual interference and misinformation, a novel grating needs to be researched, developed and innovated to solve the problem under the conditions that a group of gratings are installed along the linear direction, a group of gratings are installed at a folded angle between two groups, gratings are installed side by side between two groups face to face, a group of gratings are installed at a stacked height, or a group of gratings are installed at a group of axial groups.

In order to achieve the above object, the present invention provides a cooperative infrared barrier, which comprises: the cooperation line, A group infrared fence, B group infrared fence. The cooperative infrared fence has cooperative modules with communication terminals added to the main rod and the auxiliary rod, and the cooperative modules are software controlled program embedded into CPU monochip computer and have hardware as control executing circuit and communication terminals as external connection interface. The communication connecting terminals between two adjacent groups of gratings are connected by a cooperative line, so that the cooperative modules of the two groups of independent gratings are communicated by bridging of the cooperative line, and the working state is notified and the cooperative control signaling is sent. Under the working state, under the program control of a chip arranged in a cooperative module of the two groups of gratings, when a trigger condition preset by a cooperative module program is reached, the mutual conversion of the working state is carried out between the two groups of gratings in cooperation through the intercommunication state and the cooperative control signaling of the cooperative line, so that the two groups of independent cooperative gratings work in turn and repeatedly, and each group of cooperative gratings cannot be interfered by the other group of gratings in the transmitting/receiving working state, thereby thoroughly solving the mutual interference problem of the two adjacent groups of infrared gratings and innovatively creating a unique novel product capable of realizing the cooperative work of the multiple groups of infrared gratings. The method can also be popularized to solve the problem of cascade anti-interference of more than two adjacent groups of gratings.

Equivalently, A of either A-group cooperative grating_{On the upper part}A rod and A_FromThe bar is also B of a B group cooperative infrared fence_{On the upper part}A rod and B_FromThe pole, the circuit board in 4 poles all is equipped with the cooperation module of band-pass news binding post, connects A, B two sets of independent gratings with intercommunication operating condition through the line of coordinating. The connection mode of the group A of cooperative gratings and the group B of cooperative gratings can adopt one of the following four wired connection modes for connection, and the connection mode with the equivalent effect comprises the following steps: a. the_{On the upper part}Rod and B_{On the upper part}Rod connection, A_{On the upper part}Rod and B_FromRod connection, A_FromRod and B_{On the upper part}Rod connection, A_FromRod and B_FromThe rods are connected.

Equivalently, the cooperation line may be a wired connection connecting two groups of independent gratings, or a wireless or optical connection.

Preferably, the cooperative module additionally arranged inside the two groups a or B of gratings has the trigger conditions preset in the program as follows: group a or B gratings complete 1 detection cycle. When the current group of gratings in the working state reaches the triggering condition, the cooperation module sends an instruction to pause the infrared transceiving detection work which is carried out by the current group of gratings, and sends a cooperation control signaling to send another group of gratings in the standby state through the cooperation line intercommunication state, so that the cooperation module starts the transceiving detection work of the infrared light, and does not pause the work until the triggering condition is reached, and sends a cooperation control signaling back through the cooperation line intercommunication state. Thus, the two groups of independent gratings A and B alternate in rotation in a cycle and a cycle.

Compared with the prior art, the invention has the beneficial effects that: under the control of the cooperation module, the infrared fence gratings of 2 adjacent groups which independently function can cooperate to work in turn, and the interference of another group of gratings can not be received when each group of gratings works, so that the problem of mutual interference between 2 groups of gratings is solved, and unique novel products capable of realizing the cooperative work of a plurality of groups of infrared fences are manufactured to meet the market demand.
