Problems solved by technology

The above two defects first make the product work, due to the discreteness of the component parameters and the distribution of the product production process, the consistency of the infrared pulse signal intensity received by each infrared receiver is poor, so that the overall consistency of the product is poor.
Secondly, the product is not only disturbed by environmental factors but also inevitably has faults during use. Since the existing technology cannot accurately detect the intensity of the infrared pulse signal it receives, it cannot perform a self-check function on the working status of the product, which is easy to cause Inaccurate alignment, failure of a certain optical path, interference from various environments, or mass-intensive installation, each infrared emitter in the overall environment space emits a large number of infrared pulse signals with design margin strength and interferes with each other, causing false alarms , or a large number of infrared pulse signals with design margin strength cause leakage alarm due to refraction

Embodiment Construction

[0026] Such as figure 1 As shown, the intelligent adjustment method of the infrared anti-theft net of the present invention is to adjust the intensity of the infrared pulse signal emitted by the infrared transmitter so that the intensity of the infrared pulse signal received by the infrared receiver is consistent under different external conditions.

[0027] It specifically includes the following steps:

[0028] (1) setting the demand value of the intensity of the infrared pulse signal received by each infrared receiver;

[0029] (2) Detect the intensity of the infrared pulse signal actually received by each infrared receiver;

[0030] (3) compare the actual detection value with the preset demand value;

[0031] (4) Regulate the intensity of the infrared pulse signal emitted by the corresponding infrared emitter according to the comparison result.

[0032] In the specific operation, when the power is first installed, the intensity of the infrared pulse signal sent by each i...

Abstract

The invention discloses an intelligent adjusting method of infrared anti-theft network, which compares the infrared impulse signal intensity received by the infrared receiver with the needed value to adjust and control the infrared impulse signal intensity sent by the infrared sender. It uses the infrared impulse signal intensity received by the infrared receiver to adjust the infrared impulse signal intensity sent by the infrared sender, so that it can achieve to the needed value.

Description

【Technical field】 [0001] The invention relates to a method for adjusting an infrared anti-theft net, in particular to an intelligent adjustment method for an infrared anti-theft net that can be adjusted in good time according to the actual environment and requirements. 【Background technique】 [0002] Invention patent No. ZL99117200.0 "infrared anti-theft net", discloses that an infrared transmitter is installed at one end (transmitting end), and an infrared receiver is installed at the other end (receiving end). The I / O port of the I / O port controls the infrared transmitter and the infrared receiver, and the coding method of the pulse rays between each pair of infrared transmitter / infrared receiver is completely different" technology, which effectively realizes that the infrared receiver covers each other in multiple infrared beams The identification under certain conditions achieves the purpose of improving the defense height of infrared intrusion detectors, and constitutes...
