Among them, the access control card is equivalent to a key, which must be equipped by every person with entry authority. Electronic access control systems with access cards are becoming more and more widely used. While the electronic access control system brings convenience to people, it also adds a lot of trouble to people. The carrying, keeping and application of the card have all added a lot of inconvenience to people. There are already many kinds of cards in our work and life, and access control cards will become another burden that we cannot get rid of in our lives. There are often such regulations on the use of access control cards: access control cards should not be placed together with other magnetic cards or mobile phones to avoid degaussing and affect use. This shows that the access control card still has certain defects in the design and use.

The use of access control cards is not very flexible: For various hotels, the flow of personnel is relatively large. New guests must issue access control cards to the corresponding rooms, and guests must also withdraw them when they check out. open. The issuance, management and recycling of access control cards has become a problem, and sometimes it has even affected the normal operation of enterprises. Moreover, once the access control card is lost, the authority cannot be modified in a short time, which is easy for bad personnel to take advantage of, and at the same time poses a threat to the security of the hotel.

Based on this situation, we have designed a kind of mobile phone that does not add extra burden to people's carrying. It is more convenient and flexible to use, safer, more humanized, intelligent, and the overall design structure is simpler and more practical. It is closer to the intelligent access control system required by various hotels and other places with high personnel mobility, and it also provides a useful reference for the development of smart homes.

Detailed ways:

The intelligent electronic access control system of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

As shown in Figure 1, intelligent electronic access control system of the present invention includes electronic door lock (4), is characterized in that, is also provided with: single-chip microcomputer control circuit (1), short message transceiver module (2), clock reference module (3) , a power module (5), a flash memory (6), an extended network interface (7) and a keyboard (8).

As shown in Figure 1, the power supply module 5 includes a common switching power supply 51, which is responsible for supplying power to the entire system when the mains power is normal, and a UPS power supply 52, which is responsible for providing uninterrupted power for the system when the mains power fails. electrical energy.

As shown in Figure 1, the single-chip microcomputer control circuit can have an administrator password in the initial operation stage after the installation of the intelligent electronic access control system, and the person who masters the administrator password has the highest management authority. The single-chip microcomputer control circuit can process various control command text messages sent by the administrator or modify various functions of the intelligent electronic access control system by means of key input.

As shown in Figure 1, when the intelligent electronic access control system is applied to hotel rooms, for new guests, the administrator can set their mobile phone number as an occupant with access authority in a certain room, as long as the checking-in guests have the right to access the intelligent electronic access control system Send a text message requesting the code to get the code to enter the room.

As shown in Fig. 1, the described single-chip microcomputer control circuit can control the effective time of the personnel with different authority to use the access code to be different. The administrator can set the effective time of his own access password to be the working time or all the time of all working days. For new guests, after setting them as having the access authority of a certain room, at the same time set their access to the room according to their registered stay time. Access to the room. After the guest has the right to use the room, he can set the password usage period or times by himself. After the guest has successfully set the password usage period or number of times, if the password expires this time, you can send a password request to the access control system. After receiving the request, the access control system will check the authority of the requester, and if it is an authorized occupant, send a new access password . If you are not an authorized crew member, ignore it.

The intelligent electronic access control system is more flexible for the access management of the guests in the hotel. The administrator can set the effective time of the access authority, or the effective time of the password. Once the preset time is reached, the system will automatically delete its authority or invalidate the password it uses. In this way, the guest rooms can be effectively managed without being bothered by the management and recycling of access control cards.

For example, if a new guest wants to have access to a certain room, the administrator must first set this permission to the intelligent electronic access control system, and at the same time set the usage time of the permission according to the registered stay time. After the check-in guest has the access authority, he will send a short message to the intelligent electronic access control system to request the access code. After receiving the request, the intelligent electronic access control system verifies the authority, and sends the access code to the requesting party after passing the verification. After receiving the password, the guest can also set the usage method of the password according to his own needs, or use it once, use it multiple times, or use it regularly. In this way, the initiative of the guests to manage the safety of the guest room can be improved. At the same time reduce the management pressure of hotel managers.

As shown in FIG. 1 , the main function of the clock reference module is to provide stable real-time time information free from external interference. The password generation program of the intelligent electronic access control system is based on the time provided by the industrial clock as a parameter, and is formed through a password generation algorithm. Due to the transient nature of time, and the time when the system receives the password request is different, the time at this moment is used as the parameter The generated password is different, so the password is more confidential and cannot be easily cracked.
