recently a good friend i work unit safety precautions in order to better do the work in their work units equipped with relatively complete monitoring system this could have been one pair of units and workers are all very good thing but their annoyance has cropped up the reason is that they installed alarm frequent such as frequently as their alarm monitoring some small animals within the alarm signal is issued or monitoring environment change the alarm occurs such as temperature light and other changes occurrence of these cases the security personnel rushed to the scene promptly after receiving the alarm only to find that a false alarm alarm was originally to help people to safety precautions but because technology was the cause of once the cause then the trouble will be very big and the lightest consequence is to increase the number of unnecessary trouble affecting people 39 s normal life and work people feel tired thus greatly reduced the credibility of alarm serious consequences is the alarm sounds the alarm making even the police and security personnel rushed to the scene unnecessarily wasting a lot of police but also the normal life of people around the cause affected how to solve the false alarm has become the current face of the problem br br analysis of what caused the false alarm br the author 39 s friends for the false alarm issue was asked to solve this problem i summarize the current monitoring system in the because of the following areas br br 1 infrared intrusion alarm to the judge is not accurate enough resulting in br 2 infrared alarms caused by external environmental factors such as by temperature light and other environmental factors also air flow pet actions and other factors br br 3 host and alarms are set using the wireless encoding encoding because the host and the alarm caused by repeated high regard yards leading to br br 4 wireless alarm system anti jamming capability for the relatively poor performance likely to cause interference with the frequency of false positives br br 5 there are some alarm but the quality of relations such as component damage and poor production techniques will result in false positives br br 6 human factors can also cause false alarms user actions such as improper careless trigger alarm strayed strayed into the zone has been fortified and so on would produce false positives there a way to install equipment angle and position does not fit can cause false positives br br how to reduce the false alarm br general produce false positives of the reason is very complicated if it is to reduce alarm device of false positives the most important thing to consider from a variety of factors example choose from a performance and technical aspects of alarm this alarm options including sensors fresnel lens shape design the microprocessor program multi kam technology automatic rolling code hopping technology production processes use temperature compensation sensitivity detection range adjustment these combination of factors above are determined alarm performance and the incidence of false positives if we can solve the above mentioned factors will improve the performance of alarm false alarm rate can be reduced significantly br br the design of a new generation of infrared alarm the light of these factors a series of improvements with some unique technology to a certain extent improved the performance of alarm example the focus of the infrared lens on the application of two different circuits are connected to light and heat inductor so special lens will cover the region into multiple sensitivity ladder of protected areas ensure the protection of the region 39 s signal strength unique infrared lens can also act as filters the surface of treated black visible and shortwave infrared lens allows into the goal and then absorbed by their black base
