[0004] The launcher of the above-mentioned theft-preventing alarm is generally powered by a battery, so when the power is insufficient, it loses its function of preventing theft. Therefore, how to save power consumption has become an important issue in the design of this alarm. Existing theft-prevention alarms have been set at the factory with a good sensitivity, and the user cannot adjust the critical distance between the transmitting device and the receiving and alarming device. For example, in crowded places, a smaller critical distance is required, but Existing theft prevention alarms cannot meet this requirement
Therefore, the above-mentioned existing theft prevention type siren has its unsatisfactory parts, and there is a need for improvement

A wireless electronic lock and its locking method features that it has a transmitter and a receiver for transmitting and receiving radio signals. An original definition code is transmitted from said transmitter to receiver and then stored in the receiver. Then a link code is transmitted from transmitter to the receiver at intervals. In the receiver, the link code is compared with said original definition code to obtain an error code rate, which is then compared with a critical value. When the error code rate is higher than the critical value, a warning signal is generated.
Description
technical field [0001] The invention relates to a wireless electronic lock, in particular to a wireless electronic lock capable of preventing items from being stolen and a locking method thereof. Background technique [0002] Most of the current electronic products are manufactured to be light, thin and short for easy portability. However, thin and short items have the disadvantage of being easily lost. For example, on the exhibition ground, sellers almost always place commodities or electronic products on the exhibition ground for display, or for users to try out. However, due to the large number of people on the exhibition ground, the exhibits are easy to be stolen. In addition, incidents of missing children often occur in society. When parents are shopping or taking their children to the park to play, children are often lost due to too many tourists. [0003] In order to solve the above problems, the design of so-called theft-prevention siren is produced, which is to p...
