Description

The present invention relates to a card lock device used off-line.

More specifically, at least check whether the data read from the inserted card satisfies a predetermined condition,
The present invention relates to a card lock device that controls whether or not to unlock depending on the result.

[Prior Art and Its Deficiencies] Even with a card lock device having the same configuration, items to be checked for data read from a card inserted therein may be different depending on the installation position.

For example, as shown in FIG. 5, in the card lock device L ₀ installed at the entrance / exit of the building B, only the building number (or building name, the same applies hereinafter) is the check item, and the entrance / exit of each room in the building is With the installed card lock devices L _{1 to} L ₅ ,
Only the building number and tenant number (or tenant name, the same below) or tenant number are the check items, and the card lock device installed at the entrance of the attached parking lot of the building
The L _6, is a check item of the parking contract number and expiration period.

In this way, when the check items differ depending on the installation position, and when each card lock device operates offline, it is necessary to set the check items independently in each card lock device.

Conventionally, each card lock device is provided with a digital switch for each item, and each switch is set ON / OFF depending on whether or not to set as a check item.

Therefore, since the number of digital switches is the same as the number of check items, there are problems such as installation space problems, man-hours problems, and the possibility of incorrect settings, and it is not easy to change the setting items. It was

[Technical Problem to be Solved] This invention, like the time of unlocking, only requires insertion of a card,
By making it easy to set and change check items, the problem of the switch installation space, operating time, and the possibility of erroneous settings associated with the use of the above conventional switches is eliminated by eliminating the need for setting switches. The purpose is to

[Means for Solving the Problem] In order to solve the above-mentioned problems, a card lock device according to the present invention includes: (a) based on data read from the card reader,
A card type determination means for determining the type of card used, (b) when the used card is a user card,
Equipped with a card validity judging means for judging the validity of the data read from the card, (c) when the used card is an administrator card,
A setting item search means for identifying an item set as data to be checked from the data read from the card is provided, and (d) among the data to be checked read from the administrator card, the set item is stored in the memory. It is characterized in that a setting item registration means for registering is provided.

[Operation] The card reader reads data from the inserted card and gives it to the arithmetic processing unit.

In the arithmetic processing unit, first, based on the input data, the card in which the card type determining means is inserted into the card reader, that is, whether the card that has just been used is the user card,
Determine if it is an administrator card.

Here, the user card refers to a card used by the facility user to unlock the facility by entering and leaving the facility. The administrator card is a card used by the administrator for maintenance, management, setting unlocking conditions, etc. of the card lock device.

The user card determines the validity of the card. For example, individual identification data (ID data), expiration date, building number, tenant number, parking contract number, etc. Any one of the data defining the range or any combination thereof is recorded.

On the other hand, the administrator card has a check that specifies each data corresponding to the check items that can be set in the card lock device of the same structure under the control, and whether or not to set the corresponding data. Designated data is recorded.

If the inserted card is determined to be a user card, the card type determination means sends a determination signal to that effect to the valid determination means, and if it is determined to be an administrator card, a determination signal to that effect is sent. It is output to each of the setting item search means.

Based on the input of the user card determination signal from the card type determination means, the validity determination means determines the validity of the data read from the card (eg validity of building number, tenant number, validity period, etc.) from the memory. The data is checked by comparing it with the read data to be checked. When it is determined to be valid, the unlock command signal is output to the electric lock connected to the subsequent stage of the arithmetic processing unit. Based on this, the electric lock performs the unlocking operation.

In addition, the setting item search means searches for the data to which the check designation data is added from the data currently read from the card based on the input of the manager card determination signal from the card type determination means, and performs the check. Decide what to do.

When the setting item search means searches the check designation data and outputs the corresponding data, the setting item search means registers the data in the memory as data to be checked by the card lock device.

With this, in the card lock device, when it is determined that the card to be inserted thereafter is the user card,
With respect to the data read from this card, the check is performed for the item that the data means.

[Embodiment of the Invention] Next, an embodiment of the invention will be described with reference to the drawings.

The card lock device according to the present invention, like the conventional device, has a card reader 1, a memory 2, and an arithmetic processing unit (CPU) 3.
And an electric lock 4. However, the present invention is not limited to a card-only one, but can be applied to a combination type of a card and a keyboard such as a numeric keypad.

When the magnetic card is inserted, the card reader 1 magnetically reads the data recorded on the recording surface, converts the data into an electric signal, and outputs the electric signal to the arithmetic processing unit 3. There are two types of cards used in this device, a user card C ₁ and an administrator card C ₂ , as illustrated in FIGS. 2 and 3.

User card C ₁ contains data that specifies the card type.
D ₁ and data D ₂ to be checked are recorded. The contents of the data to be checked may be various depending on the usage of the object to which the card lock device is installed, but, for example, a building number, a tenant number, a parking contract number, and a validity period.

Similarly, the administrator card C ₂ has data D ₁ that defines the card type, data D _{21 to} D _{2n for} all items to be checked by the card lock device under control, and check designation data D ₃ Is recorded. The check designation data is added only to the data to be checked by the card lock device among all the items.

In the card lock device according to the present invention, the arithmetic processing device 3 includes a card type determination means 31 and a validity determination means 32.
And a setting item search means 33 and a setting item registration means 34.

The card type determination means 31 determines the type of card used based on the data read by the card reader 1. The card validity judging means 32 judges the validity of the data read from the card when the used card is a user card. When the card used is an administrator card, the setting item searching means 33 searches the data read from the card for an item set as data to be checked. The setting item registration means 34 registers the set item in the memory among the data to be checked read from the administrator card.

 These operations will be described in more detail with reference to FIG.

When the arithmetic processing unit 3 receives data from the card reader, the arithmetic processing unit 3 stores the data in the temporary storage unit, and supplies the data in the recording area defining the card type to the card type determination unit 31. Further, the data representing the types of the user card and the administrator card recorded in the memory 2 are sequentially read and given to the card type determination means 31.

As a result, the card type determination means 31 sequentially compares the data read from the card with the data read from the memory, determines the card type based on the presence or absence of the matched data (p ₁ ), and outputs the user card determination signal u. In the validity determining means 32,
Alternatively, the administrator card determination signal s is sent to the setting item search means 33,
Output each.

When the user card determination signal u is input, the validity determination means 32 compares the data read from the recording area of the data to be checked of the card with the data to be checked previously registered in the memory, and the matching data is obtained. Whether the card is valid or not is judged (p ₂ ). If there is matching data, and outputs the unlock command signal to the subsequent electric lock 4 (p _3). The electric lock performs the unlocking operation based on this. However, if there is no matching data, the validity determining means does not output the unlocking command signal, so that the electric lock is held in the locked state.

On the other hand, when the setting item search means 33 receives the administrator card determination signal s, the setting item search means 33 selects from the data read from the card,
Checks whether the check specified data is added to data corresponding to the recording area of the data to be checked (p _4). When the check specified data is detected,
The data corresponding to the check designation data is read and the data or the number corresponding to the check designation data is given to the setting item registration means 34.

Based on this, the setting item registration means 34 performs the check read from the primary storage unit or another storage area of the memory 2 based on the number corresponding to the data to be checked or the check designation data input from the setting item search means. The power data is stored in the memory 2 (p ₅ ).

For example, as shown in FIG. 3, when the administrator card in which the check designation data is recorded for the tenant number is inserted into the card reader 1, as the data to be checked in the memory of the card lock device, The tenant number is registered.

In the above embodiment, the data read from the card was used for registering the data to be checked in the memory. However, the data corresponding to each check item is stored in the memory in advance, and the stored data Of these, the data corresponding to the card check designation data can be registered as the data to be checked.

If the check item needs to be changed, the check item can be changed easily and simply by inserting the administrator card in which other check designation data is recorded into the card reader of this device.

[Effects of the Invention] As described above, the card lock device according to the invention is
The type of inserted card is determined, and if it is an administrator card, the data to be checked in the memory is registered based on the check designation data recorded on that card. Similarly to the case where the user unlocks the card, the person can also set the check items by a simple operation of inserting the card. Also, the check items can be changed at any time as necessary.

Further, since the switch for setting the check item is not required, the defects in the conventional device such as switch installation space, setting labor, and erroneous setting are completely eliminated.
