Description

  The present invention relates to an electric lock wiring system that electrically connects an electric lock provided on a door (including a sliding door) and an operation panel disposed at a location away from the electric lock.

  FIG. 4 is a block diagram showing a conventional electric lock wiring system X. As shown in FIG. Referring to FIG. 4, reference numeral 1 denotes an electric lock attached to a door (including a sliding door). As is well known, the electric lock is attached to the free end portion of the door in a built-in manner or an imposition manner, and a drive source (solenoid or motor) 2 is provided in the lock box. It moves forward and backward by the driving force of the source 2.

  On the other hand, 3 is an operation panel including a remote control unit (electric lock control unit) 4 disposed in a place (for example, a wall of a building other than the door) different from the electric lock 1 on the door side. Is connected to a commercial power supply (AC100V). The operation panel 3 includes, for example, an AC / DC converter 5 and an operation panel side connector 6.

  As is well known, the operation panel 3 includes a card controller capable of reading ID information of an ID card such as a magnetic card, input means for receiving an operation signal from an operation button, an input signal obtained from the input means, and an internal memory. A CPU circuit that collates data with the registration information stored in the computer.

  Now, a portion surrounded by an imaginary line between the electric lock 1 and the operation panel 3 in FIG. Here, the “current-carrying metal fitting 7” refers to all of engraved type, surfaced type, arm type, hinge type, pivot type and the like. Since the specific configuration of all types of current-carrying metal fittings is a well-known matter described in, for example, the applicant's catalog, detailed description is omitted, but the engraved mold is used for wiring between the door and the frame. It refers to a carved type case-like metal fitting, for example, the applicant's product number TEK-9CC type. Further, the surface mounting type refers to a surface mounting type case-shaped metal fitting for passing between the door and the frame, for example, the applicant's product number TEJ-9 type. Further, the hinge type refers to a hinge-type pipe-shaped metal fitting for passing between the door and the frame, for example, the applicant's product number TED-8CC type. The same applies to the pivot type.

  Here, the engraving mold will be described as an example. Returning to the portion surrounded by the imaginary line described above, reference numeral 8 denotes a door, and a first energization fitting 9 is attached to the hanging side of the door 8. Since the case body having the vertical mounting plate of the first current-carrying metal fitting 9 is engraved and attached to the hanging side of the door 8, those skilled in the art refer to it as “engraved type”. Reference numeral 10 denotes a first connector on the first current-carrying metal fitting 9 side.

  On the other hand, reference numeral 11 denotes a frame (door frame), and a case body having a vertical mounting plate for the second current-carrying metal fitting 12 is attached to the frame 11 in a position opposite to the case body of the first current-carrying metal fitting 9. It is done. Reference numeral 13 denotes a second connector on the second energizing metal fitting 12 side. As described above, those skilled in the art refer to the two appliances on the door side and the frame side for wiring between the door and the frame, not as a “connection or wiring case” but as an “energizing bracket”. .

  Thus, in the conventional electric lock wiring system X including the current-carrying metal fitting 7, no attempt has been made to transmit LAN data, and so-called many electric wires have been used. Those skilled in the art refer to these numerous electric wires as “wiring cords” or “lead wires”. A number of electric wires referred to as the wiring cords are merely connected between the electric lock 1 and the operation panel 3, but at least the first wires (two) 14 for supplying power from the operation panel 3 and The second wiring (total 4 to 5) 15 for receiving the status signal b such as the lock confirmation signal, the release confirmation signal and the door closing confirmation signal based on the operation of the relay from the electric lock 1 is necessary.

Therefore, the conventional electric lock wiring system X has problems as pointed out below.
(A) Special knowledge is required for the wiring between the current-carrying metal fittings and the electric lock / remote control unit, which sometimes causes incorrect wiring, resulting in malfunction and failure.
(B) Locations and routes through which wiring is performed are limited, and the distance from the remote control unit to the electric lock is limited to 120 m, for example, when the conductor diameter of the wiring is 0.9 mm.
(C) The wiring construction of the power supply requires qualification, which is limited to the installer and increases the wiring construction cost.

  In addition, Patent Document 1 describes a matter in which an interface panel for an electric lock is integrally attached to the rear end portion of the first energizing bracket on the engraved door side. It is a signal conversion means interposed between the lock and the operation circuit of the operation panel, and its function is different from a LAN connector (LAN data connection means) described later of the present invention.

  Patent Document 2 describes matters relating to a LAN / SIF conversion device for connecting a local network (LAN) of a host computer and a SIF printer having a serial interface (SIF) in the field of telecommunications equipment. Yes. For example, as described in Patent Document 2, it is a well-known matter to use a LAN cable in the field of telecommunications equipment.

Explanatory drawing which shows the other Example different from 1st Example of this invention. The block diagram of the conventional wiring system X for electric locks.

  The best mode for carrying out the invention will be described with reference to FIG. In describing the electric lock wiring system X1 of the present invention, the same or similar parts as those of the conventional electric lock wiring system X are denoted by the same or similar reference numerals, and redundant description is omitted. The present invention is characterized in that an “Ethernet serial conversion device” and a “PoE power receiving device” are provided in the current-carrying metal fitting, for example, the second current-carrying metal fitting 12. The connection target from the first energizing metal fitting (door side) 9 is connected to an intelligent electric lock 1 capable of serial communication or an electric lock adapter having the same function.

  On the other hand, the exchange of signals between the second energizing metal fitting (frame side) 12 and the remote controller 4 on the operation panel 3 side (transmission of command signal a relating to locking / unlocking, reception of return status signal b) Since a LAN cable is used as power supply and data transmission means, a PoE power supply function-equipped HUB or a PoE power supply function-equipped adapter is used as the relay means.

  FIG. 1 is a block diagram of an electric lock wiring system X1 of the present invention. This will be described with reference to FIG. First, reference numeral 1A on the left side of FIG. 1 is an electric lock referred to by the applicant as an “intelligent electric lock”. The electric lock 1A includes a lock control unit 21 inside or outside the lock box (for example, inside the door 8).

  The lock control unit 21 receives a lock command signal and an unlock from the serial / Ethernet (referred to as “S / E” for convenience) conversion control unit in the second energization fitting 12A via the first connector 10A on the first energization fitting 9A side. When a serial status signal (conversion data) a such as a command signal is received, the serial status signal a is controlled so as to instruct locking or unlocking of the electric lock 1A.

  Further, when the lock control unit 21 receives a status signal b such as a lock confirmation signal, an unlock confirmation signal, or a door closure confirmation signal via a micro switch provided in the lock box of the electric lock 1A, the lock control unit 21 receives the status signal b. The data is output to the Ethernet control unit (remote control unit) 4A side of the operation panel 3A. Therefore, the lock control unit 21 controls input / output of the serial state signal a and the state signal b.

  Further, when the electric lock 1A receives a DC power source, for example, DC 24V, converted from the operation panel 3A side through the DC voltage converting means in the current-carrying metal fitting, for example, the second current-carrying metal fitting 12A, a motor as the drive source 2 Or energization control is performed on the solenoid.

  Next, reference numeral 3A on the right side of FIG. 1 is an operation panel provided directly or indirectly with an Ethernet control unit (herein referred to as "remote control unit") 4A side. The operation panel 3A is disposed on the wall surface of a building at a location 350 meters or 400 meters away from the electric lock 1A, for example. Similarly to the conventional remote control unit 4, the Ethernet control unit 4A is also a card controller that can read ID information of an ID card such as a magnetic card, an input unit that receives an operation signal from an operation button, and the like. The CPU includes a CPU circuit that collates data between the input signal acquired from the above and the registration information stored in the internal memory. However, the remote control unit 4A is different from the conventional remote control unit 4 in that it is for Ethernet.

  Thus, 13A is a LAN connector (LAN data connection means) provided on the second energizing metal fitting 12A. The LAN connector 13A and the remote control unit 4A are a single unit having the LAN cable 22 and a power supply function (PoE power supply device). Alternatively, a plurality of relay means (having a function of converting alternating current into direct current) 23 are connected to each other. Therefore, the LAN data in the packet state can be transmitted in a serial state from the operation panel 3A (remote control unit 4A) via the LAN cable 22. In addition, the operation panel 3A is connected to the electric lock 1A (lock control unit) via the LAN cable 22 and the relay means 23 and via a serial / Ethernet (S / E) conversion control unit 25 provided in the second energizing bracket 12A. The status signal from 21) can be received.

  Incidentally, as is well known, the LAN cable 22 has been determined to have a power feeding function (IEEE802, 3af-2003). Therefore, electricity flows through the LAN cable 22 in the same manner as a telephone line.

  Therefore, the LAN connector 13A described above physically divides the LAN data received from the LAN cable 22, and a serial / Ethernet (S / E) conversion control unit 25 provided in the second energizing metal fitting 12A, and a direct current Each is sent to the voltage conversion means 26. The DC voltage conversion means 26 is provided on a substrate (not shown) including a voltage conversion element. Here, a DC / DC converter circuit will be described. The reason why this DC / DC converter circuit is necessary is as follows.

  As shown in FIG. 1, the DC voltage on the LAN cable 22 side output from the LAN connector 13A is, for example, DC 48V. On the other hand, the DC voltage on the electric lock 1A side is, for example, DC 24V. That is, since the direct current voltage 48V obtained from the LAN cable 22 and the direct current voltage 24V used for starting the drive source of the electric lock 1A do not coincide with each other, the direct current voltage conversion means (DC / DC converter) in the second energizing metal fitting 12A. It is necessary to convert the DC voltage 48V obtained from the LAN cable 22 into a DC voltage 24V suitable for the voltage for the drive source 2 of the electric lock.

  Reference numeral 14 denotes a first wiring (electric wire) similar to that of the conventional example. The first wiring (electric wire) 14 includes a DC voltage conversion means 26, the first connector 10A, and the first connector 10A and an electric lock. Each is connected to 1A or an electric lock adapter having the same function. Reference numeral 15A denotes a part of the second wiring in the conventional example replaced with a serial cable. The serial cable 15A includes a serial / Ethernet (S / E) conversion control unit 25, the first connector 10A, and the first connector. 1 connector 10A is connected to an electric lock 1A or an electric lock adapter having the same function. Since the structure of LAN data (protocol header etc.) transmitted by the LAN cable 22 is a well-known matter, the description thereof is omitted.

  In FIG. 1, the LAN connector 13A, the serial / Ethernet (S / E) conversion control unit 25, and the DC voltage conversion means 26 are provided in the second energizing metal fitting 12A. Of course, the LAN connector 13A, serial / Ethernet ( S / E) The conversion control unit 25 and the DC voltage conversion means 26 may be provided in the first energization fitting 9A (not shown).

  Further, as shown in FIG. 3, a LAN connector 13B as LAN information connecting means is provided in the second energizing metal fitting 12B, while a serial / Ethernet (S / E) conversion control unit for receiving LAN information from the LAN connector 13B. 25 and the DC voltage conversion means 26 that receives power from the LAN connector 13B may be provided in the first energization fitting 9B. As described above, even if the arrangement positions of the information receiving mechanism and the information converting mechanism are appropriately changed, the same object as the present invention can be achieved. Accordingly, the layout of the LAN connector, the information receiving mechanism, and the information converting mechanism can be changed without departing from the object of the invention.

  The present invention is used in the fields of locks and joinery.
