Abstract

(57) [Summary] [PROBLEMS] This invention controls an electronic lock by automatically recognizing ID data unique to a non-power supply and non-contact IC chip and data specifying an electronic reader that reads the data by a PC (personal computer). It is a security lock system. An IC chip on which unique ID data different from each other are recorded is used as an ID key, and character code data for specifying a data reader for reading the data is used as data unique to the IC chip. The electronic lock 9 is controlled by automatic recognition by the PC 7 serving as the data base 10.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 According to the present invention, when there are a plurality of persons who operate the opening / closing control of the lock by the electronic locks installed at a plurality of locations, the ICs in which the unique ID information is written are automatically recognized and controlled. At the same time, it is possible to identify the part that is electronically locked and the person who controlled the electronic lock.

[0002]

[Prior art]

 Conventionally, automatic recognition systems based on magnetic or printed barcodes are of the contact type, and there is a limit to the amount of required information, but it is not possible to set a unique ID for each application. This system is difficult to read the written information, and is not suitable for automatic recognition that requires confidentiality.

[0003]

[Problems to be solved by the invention]

 Opening and closing of locks is often performed directly mechanically, which makes it easy to use counterfeit products or break keyholes, which has led to the loss of key security and security. It is conceivable that opening and closing are performed by electronic lock control, but this must be a non-contact type system that can not be counterfeited remotely, and all the current situations where lock systems are diversified As a possible security method, when multiple people operate the opening and closing of the locks installed at multiple locations, each installation location and each person who uses them has a different ID code, and each ID code is automatically This is a security system that controls locking based on recognition.

[0004]

[Means for Solving the Problems]

 A data reader corresponding to each of the electronic locks installed at a plurality of locations is installed. The person who controls the electronic lock has a non-power / non-contact type IC chip on which an ID code is recorded. The ID code of this IC chip can be read by a data reader, and by reading this ID data, the person who controls the electronic lock can be specified, and the ID code of the IC chip read by the data reader can be specified. The data output signal is supplied to a server terminal having a multi-channel input circuit, and the server terminal detects the input signal and generates a character code for identifying a plurality of connected data readers. The ID code data of the IC chip and the data identified by the automatic recognition system by accessing the personal computer · To control the electronic lock that corresponds to the leader.

[0005]

[Embodiment of the invention]

 A non-power-supply, non-contact type IC chip 1 that operates with electromotive force induced by the electromagnetic wave 3 and has a storage capacity of 64 bytes or more is stored in advance as an ID code with a tamper-resistant and erasable serial number that is different from the others. It is also possible to store necessary information separately. The IC chip 1 is mounted on a device having a shape that is easy to handle, and is placed as an ID key 2 close to the data reader 4 corresponding to the electronic lock 9. Then, the data of the IC chip 1 is read.

A data reader 4 for reading data of an IC chip 1 mounted on an ID key 2 has a function of transmitting an electromagnetic wave 3 serving as a power source of the IC chip 1 and a function of transmitting an electromagnetic wave 3 for carrying data from the IC chip 1. It has the function of receiving and demodulating data into digital signals. By connecting its output signal to the multi-channel input server terminal A5, a plurality of data readers 4 can be connected. By detecting an output signal of the data reader 4 reading the data of the chip 1 and setting a unique character code for selecting each data reader 4, the IC chip 1 is selected from the data reader 4. Identify the data reader 4 that has read the ID data.

[0007] The data read from the IC chip 1 and the character code data specifying the data reader 4 are connected to a PC (personal computer) 7 that performs automatic recognition of a lock system as an output of a server terminal A5. The data is input to the interface 6 and the PC 7 is accessed as data for automatic recognition. The data and the ID data unique to the IC chip 1 pre-installed in the PC 7 are automatically recognized by the PC 7 using the database 10. In this case, the signal of the selection data for controlling the electronic lock 9 corresponding to the specified data reader 4 is connected from the PC 7 to the server terminal B8 having the selection function through the interface 6 through the interface 6, and the control signal is sent to the specified electronic lock 9. Supply.

[0008]

[Effect of the invention]

 When the electronic lock 9 is controlled by the security lock system, ID data and information data unique to the IC chip 1 mounted on the ID key 2 possessed by the person are used as data for automatic recognition and automatic identification. The character code data specifying the electronic lock 9 to be controlled is also used as automatic recognition and automatic identification data, and the ID data unique to the IC chip 1 is installed as a data base 10 in the PC 7 which is installed in advance. The electronic lock 9 can be entered and the security lock unique ID data, character code, and PC 7 can be instantly opened and closed by the control of the electronic lock 9 with a three-stage system and recorded. And a more precise and advanced security lock system.
