Design scheme for enhancing anti-theft door modern performance

Abstract

A design solution for improving modern performance of a theft-proof door belongs to mechanical and electric integration technical field. The inventor reuses own three items of inventive result and improves to form a reliable solution taking a telephone as the mechanical key to open the door, which scientifically solves various contradiction. The invention takes a seated phone, mobile phone namely general communicator as a receiver of the door opening signal, and is composed of a sampling circuit, an amplifying circuit, memory circuit, an eliminating resetting circuit, a control circuit and an automatic manual double-use lock, etc. The main principle is to take out the calling door opening signal from the receiver, processed by the circuits to form a door opening signal. The advantages is as follows, opening door is so modern without key that the invention can be operated by remote control in long distance, which is modern, with new trend and good accidental resistance. The most prominence is to ensure the integrity of the communication parts in the sampling process, so the invention has high comprehensive use value.

Description

technical field [0001] The invention is a technical solution for receiving an anti-theft door opening signal command by a communication phone, and mainly belongs to the technical field of electromechanical integration. technical background [0002] With the improvement of living standards, the society has higher and higher requirements for anti-theft doors, which require good safety performance, convenient operation and fashion, and good accident prevention. [0003] Judging from the current situation of the market, most of the door locks of anti-theft doors are general-purpose mechanical pin locks, which can be opened manually, are easy to break, and have low technological content. They are in a "primitive state" and are difficult to adapt to the needs of modern society. Some automatic lock class anti-theft doors have gradually occurred on the market at present, but consult relevant data, the relevant patent of opening the door with the mode of telephone call is seldom.

Problems solved by technology

Use the telephone as the receiver to receive the door opening signal of the call. It is convenient for users to use, does not carry a key, is fashionable, suitable for modern needs, and has greatly improved performance, but there are many serious problems that are difficult to solve: 1. If the receiver uses a wired The transmitted landline is easy to lose the secret because of the small number of digits, and once the secret is lost, it is not easy to change the number

2. If the receiver adopts a mobile phone transmitted by radio network, there will be a lot of spam text messages, which will cause many disadvantages. 3. Both types of phones may receive calls (commonly known as wild calls) by mistake, and form a signal to open the door by mistake. In order to solve the above problems, there are mainly two methods at present. The principle of the first method is to use the communication transmission line, and a new device a is installed on the communication transmission line as a "receiver" for receiving the call to open the door signal. When device a receives the calling number, it performs the first identification. After the identification is confirmed, an off-hook procedure similar to that of an ordinary telephone is generated. After that, the new device device a prompts the caller for the second password call by voice. Secondary recognition, output door open signal after confirmation

The implementation of the above method has greatly improved the performance of the anti-theft door, but it still needs to be developed, mainly in the following aspects, 1, with the first method, it is not very convenient when calling to open the door, because when entering the password for the second time Because the mobile phone is already in the open state, many mobile phones cannot dial the number for the second time by extracting the signal stored in advance in the mobile phone at present. At this time, the traditional method can only be used to press one key and then press another key continuously. The password required for the secondary requirement has fewer digits and fewer keys to press, but the security level is low; the number of code digits is relatively high, but the security level is relatively high, but the memory for it is increased, and the operation is troublesome. 2. When the password needs to be changed in the first method, The addition of new technological content and new equipment brings obstacles to popularization. 3. It is relatively difficult to produce "receivers" according to the first method

4. The second method will lose a lot of the essence of remote control fashion because it cannot take advantage of the network, which is less meaningful
