The burglar alarm lock is called the alarm lock. Taiwan calls it the alarm lock. The principle is the same, that is, when someone is illegally opened or violently destroyed, the alarm lock immediately emits a high-decibel siren, and some can also automatically dial the user's phone to remotely notify the owner (currently only for home locks and businesses) Lock), in order to deter and intimidate to achieve early warning, so that thieves to renounce theft, and always achieve the protection of people's lives and property security. Because of its distinctive functional features and reasonable price, it has been favored by many consumers and enthusiasm for merchants. Although the technology of the alarm lock seems simple, there are very few manufacturers who can fully grasp the technical characteristics. Here I will elaborate on the technical mystery of the alarm lock, so that all people have a comprehensive technical knowledge to make it Become the true patron of the people!
We will expose this technology mystery from the alarm locks of transportation, home improvement, commerce, industry and personal. This article mainly introduces traffic alarm locks. Traffic locks are also called U-locks, commonly known as large locks. Mainly used in bicycles, electric vehicles, motorcycles and battery cars, and some are also used to lock glass doors or lock doors on large vans. The general situation is to use outdoors, long-term wind and rain, summer It is strictly battered by the heat, the winter is eroded by ice and snow, there are thunders outside, and there are vibrations around it, all in a harsh environment. It is not affected by ordinary mechanical locks, but if it is for alarm locks, it is not a simple matter, because it is necessary to ensure that all electronic components can be used for a long time under these harsh environmental conditions. It is a difficult and complicated project. We will elaborate on four aspects.
First, the oversized alarm is the basic feature of the traffic alarm lock.
The alarm sound is the basic feature of all alarm locks. How to make the sound bigger than the ordinary battery on the small lock body is not a general technology. The sound of the alarm lock is determined by the following three aspects:
1. The material of the buzzer sheet, the material of the buzzer currently used on the alarm lock is made of iron, copper and stainless steel. Usually made of copper, sound good, anti-oxidation. Iron is easy to embroider, the sound is very poor, all life is short and easy to break. Our company usually uses copper, and the export is made of stainless steel. The sound of stainless steel is large and crisp, with strong anti-oxidation and long life.
2, IC quality and software programming technology, because the audio of the sound is controlled by the program compiled by the engineer, so the engineer's technology is the decisive factor. Secondly, the quality of IC varies greatly, a few cents cheaper, and a few dollars to tens of dollars. A good IC runs stably without losing files and has a long service life. Poor quality ICs can easily lose files and product quality is not guaranteed. Our company generally chooses domestic high-quality or imported ICs to ensure the stable operation of the products.
3, PCB board and triode and inductors and other components are playing a key role in the product, this is the professional technology I will not explain, in short, the choice of high-quality raw materials.
Second, power saving and durable is the technical guarantee of all alarm locks
Another important issue is the battery. The choice of battery directly determines the length of time the product is used. The average manufacturer chooses a cheap carbon battery, which can reduce the cost, but has a short service life and is not environmentally friendly. We generally choose alkaline mercury-free environmentally friendly batteries, which are durable and environmentally friendly.
