[0002] The anti-theft door is an important device that is closely related to life. In today's social development, it is hoped that the operation will be more convenient and the security performance will be more advanced. However, judging from the current market situation, the anti-theft door is still in the original state of manual operation. Under the environment, the security performance is low, and the new generation of
automation is still in its infancy. Under multiple functions and performances, there are still problems that do not meet the needs of the society. The main manifestations are:
[0003] 1. The contradiction between automatic and
accident prevention cannot be scientifically resolved
The performance is that some automatic lock anti-theft
doors do not have the function of manually opening the door to prevent accidents, and some have this function but are limited, such as the lock tongue has not moved in place, is in the process of movement, and encounters accidents such as power failures or malfunctions In some cases, due to structural reasons, manual failure often occurs, forming an embarrassing situation where the door cannot be opened or closed.
The
mechanical failure rate of electronic products is relatively high during use, and the maintenance is demanding. The reason is that one cannot wait for a long time to enter the house, the other is professional maintenance, and the third is that it can only be repaired on site. These defects have become the worries of users and seriously affected the Promotion of this category
[0004] 2. The contradiction between the correct sampling of the
alarm signal and the
false alarm and the contradiction between the monotonous function cannot be scientifically resolved
One of the traditional
design methods is to use a sound-activated sensor or a
vibration sensor, which uses the principle of making a sound or vibration when committing a crime, such as breaking a door, as the original sampling, and outputs the
signal after
processing. Obviously, such an
alarm signal will contain Covers a lot of false signals, because it is impossible to distinguish the loud footsteps of passers-by, or moving heavy objects, or the vibration or sound signals generated by various unexpected reasons such as children's mischief
The second is to use a
reed switch magnetic control or
light control sensor to take out the displacement
signal of opening the door, but this method cannot distinguish between a normal door opening
signal or a door opening signal caused by criminal behavior, and it can only be detected by the user after entering the house. This method is not only complicated to operate, but also easily turns the normal behavior of the user into a
false alarm; at the same time, another
disadvantage is that the alarm occurs after the door is broken, and there may be consequences
Therefore, the requirements for scientific alarms are firstly to be reliable, that is, no false alarms; secondly, to be sensitive, that is, the alarm should preferably occur before the door is broken, but it is difficult for current products to achieve such an effect. The main reason is that sampling is an important basis for design, and currently No more advanced sensors yet
[0005] 3. The contradiction of monotonous operation, most products still stay in the original state of opening the door with mechanical keys; automatic lock anti-theft
doors still stay in the state that can only be operated by
remote control, or can only be opened by communication network
It cannot scientifically solve the contradiction between "style" and "applicability" of operation. For example, young people like to use their mobile phones as keys to open the door and feel decent, but the elderly and children need mobile phones or feel that there are many buttons in the operation process, which does not meet the needs of different levels of business groups.
Achieving multi-functions will inevitably require complex circuits, but it is not conducive to production; advanced functions will inevitably require the performance of the components used, but it is easy to increase the cost
