  However, if the system is configured by wire, it takes a lot of time and money to newly install the system. Moreover, even when renovation is performed, a great amount of time and cost are similarly required.

  Therefore, an object of the present invention is to provide a wireless entrance / exit management system that can be installed in a short time at a low cost and easily.

  The invention according to claim 1 is a wireless entrance / exit management in which an electrical switchgear is provided at a plurality of entrances in a building such as a building, and entrance / exit management is performed at the entrance / exit using the electrical switchgear information of the electrical switchgear. A system that is capable of bidirectional communication and is connected to the electrical switchgear and that controls the locking and unlocking of the electrical switchgear and can be bidirectionally communicated with each of the electrical switches A host terminal that captures the opening / closing information of the device, and each of the host terminal and the plurality of gate terminals has a unique address, and for each information collection signal transmitted from the host terminal by the gate terminal, A ring-type wireless network in which a gate terminal sequentially adds opening / closing information of each electric switching device together with the address, and is finally received by the host terminal and ends wireless communication. Characterized in that it constitutes a chromatography click. In the communication between the host terminal and the gate terminal or between the gate terminals, it is desirable to encrypt the contents such as the address and the opening / closing information of the electric switching device.

  In this way, in the management of a plurality of entrances and exits in a building such as a building, an electrical switchgear provided at the entrance and exit of each door, window, etc. that requires monitoring (for example, an electric lock, an auxiliary lock, an authentication reader, etc.) Since the gate terminals are electrically connected to each other, the opening / closing information of the electric switchgear at the entrance / exit is sent to the information collection signal transmitted from the host terminal as the start point of communication by each gate terminal. It is added sequentially. An information collection signal to which opening / closing information of all electric switchgears is added is taken into the host terminal as an end point of communication, and entry / exit management at each entrance / exit is performed using the information.

  Since the host terminal and the plurality of gate terminals form a ring-type wireless network using the host terminal as the communication start point and end point, the time and cost required for new installation and repair are greatly reduced.

  The host terminal and the plurality of gate terminals each have a unique frequency for communication, and each of the gate terminals is a transmission side of each of the gate terminals. Alternatively, when an information collection signal of a frequency specific to a specific gate terminal is received, the opening / closing information of the electric switchgear is added together with the address, and the host terminal or the specific gate serving as the receiving side of each gate terminal It is desirable to send it to the terminal.

  In this way, each of the host terminal and each gate terminal not only has a unique address, but each gate terminal and the host terminal communicate with each other at a unique frequency. Each gate terminal can improve communication reliability.

The abnormality determination unit according to claim 5, wherein each of the gate terminals receives at least one of a locking abnormality, an unlocking abnormality, an opening abnormality, and a door destruction abnormality in response to a signal from the electric switchgear. Preferably, each gate terminal adds abnormality information instead of the opening / closing information to the information collection signal when the abnormality determining unit determines that the abnormality is present.

  In this way, if an abnormality (locking abnormality, unlocking abnormality, opening abnormality or door breaking abnormality) occurs in any of the electrical switching devices, the corresponding electrical switching device is connected through the corresponding gate terminal. Abnormality can be notified to the host terminal.

  Since the present invention wirelessly communicates between the host terminal and the gate terminal as described above, it is possible to reduce the time and cost required for new installation and renovation. In particular, if each of the host terminal and the plurality of gate terminals has not only a unique address but also a unique frequency for communication, compared to general wireless communication using the same frequency in all terminals. , Improve reliability.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This embodiment is used for a building such as a building having three doorways that requires monitoring, and uses gate opening / closing information such as doors or windows provided at the doorway. The entrance / exit is managed at each entrance / exit.

  FIG. 1 is a block diagram showing a schematic configuration of a wireless entrance / exit management system according to the present invention.

  As shown in FIG. 1, the wireless entrance / exit management system 1 uses the open / closed state of the three gates 2A, 2B, 2C, and is installed in the management center 3 (host) and connected to the upper management apparatus 3A. Host terminals 3B and gate terminals 6A, 6B connected to electric locks 4A, 4B, 4C of each gate 2A-2C and card readers 5A, 5B, 5C (electric switchgear) provided on each gate 2A-2C, 6C constitutes a wireless network having the host terminal 3B as the start point and end point of communication.

  The host terminal 3B is capable of bidirectional communication, has a unique address, and captures opening / closing information about the electric locks 4A to 4C and the card readers 5A to 5C. The host terminal 3B is connected to a management upper device 3A (for example, a personal computer), and the device 3A controls and monitors the electric locks 4A to 4C and the card readers 5A to 5C connected to the gate terminals 6A to 6C. Is called. That is, the electric locks 4A to 4C and the card readers 5A to 5C are not only locked and unlocked by the gate terminals 6A to 6C, but the host terminal 3B itself is locked and controlled by the gate terminals 6A to 6C. It is also possible to perform unlocking control. As shown in FIG. 2, the host terminal 3 </ b> B includes a higher-level communication unit 11, an address setting unit 12, a CPU 13, and a wireless transmission / reception unit 15 that transmits and receives signals through the antenna 14. A power supply unit 16 is also provided.

  On the other hand, each of the gate terminals 6A to 6C is capable of bidirectional communication, has a unique address, and performs locking control and unlocking control of the electric locks 4A to 4C and the card readers 5A to 5C. Since the gate terminals 6A to 6C have the same configuration, the gate terminal 6A will be described. As shown in FIG. 3, an address setting unit 21, a reader control unit 22, an ID storage memory 23, an electric lock control unit 24, A CPU 25 and a wireless transmission / reception unit 27 that transmits and receives signals through the antenna 26 are provided. A power supply unit 28 is also provided.

  In addition, the host terminal 3B and the gate terminals 6A to 6C not only have unique address information, but also communicate with each other using unique frequencies A, B, C, and D. That is, when the host terminal 3B and each of the gate terminals 6A to 6C receive an information collection signal of a frequency specific to the host terminal 3B or the specific gate terminal that is the transmission side of the host terminal 3B and each of the gate terminals 6A to 6C. The opening / closing information of the electric locks 4A to 4C and the card readers 5A to 5C is added together with the address, and transmitted to the host terminal 3B or the host terminal 3B that is the receiving side of each of the gate terminals 6A to 6C or a specific gate terminal. Thus, since the frequency used at the time of radio | wireless communication changes according to the address of terminal 3B, 6A-6C, interference does not arise in communication between terminals.

  The communication is performed by the electric lock 4A at the first gate terminal 6A, the second gate terminal 6B, and the third gate terminal 6C in response to the information collection signal transmitted from the host terminal 3B as the communication start point according to an instruction from the host device 3A. The opening / closing information of 4C and the card readers 5A to 5C is sequentially added together with the address, and finally received by the host terminal 3B as an end point of communication, thereby constituting a ring type wireless network that terminates wireless communication. In this way, the opening / closing information of the electric locks 4A to 4C and the card readers 5A to 5C is taken into the host terminal 3B, and the information is stored in the host device 3A and used for monitoring or management. Accordingly, signals from the host terminal 3B are sequentially transmitted in a fixed order between the gate terminals 6A to 6C and finally returned to the host terminal 3B. Therefore, all the gate terminals 6A to 6C are connected to the host terminal 3B. Eliminates the need to install at a communicable distance.

  Such communication is periodically performed by the host terminal 3B according to an instruction from the host device 3A, and opening / closing information (operation information) of the electric locks 4A to 4C and the card readers 5A to 5C connected to the gate terminals 6A to 6C. ) Are sequentially collected and taken into the host terminal 3B. In this communication, control information (for example, locking command, unlocking command) from the host device 3A can be added to the signal (information collecting signal).

  Next, a specific communication procedure will be described with reference to FIG.

  First, the host terminal 3B uses an information collection signal for collecting the opening / closing information of the electric locks 4A to 4C and the card readers 5A to 5C at the respective gates 2A to 2C at its inherent frequency A as a starting point of communication. First, it transmits to the first gate terminal 6A. Then, a state of waiting for reception at the frequency B unique to the gate terminal 6A, that is, a state of waiting for a reply from the gate terminal 6A is entered.

  The first gate terminal 6A receives a signal from the host terminal 3B at a frequency A unique to the host terminal 3B, and a signal obtained by adding the opening / closing information of the first gate terminal 6A to the information collection signal at the frequency B. Are transmitted to the second gate terminal 6B, and the same signal is transmitted as a reply to the host terminal 3B. Then, at the frequency C, a reply is awaited from the second gate terminal 6B. On the other hand, when the host terminal 3B receives the reply from the first gate terminal 6A, the host terminal 3B enters a reception waiting state at the frequency D. That is, the host terminal 3B enters a standby state waiting for a signal from the third gate terminal 6C as an end point of communication.

  The second gate terminal 6B receives the signal from the second gate terminal 6B at the frequency B, and at the frequency C, adds the opening / closing information of the first gate terminal 6A to the signal as the third gate. While transmitting to the terminal 6C, the same signal is transmitted as a reply to the second gate terminal 6B. Then, at the frequency D, the state waits for a reply from the third gate terminal 6C. On the other hand, when the first gate terminal 6A receives data from the second gate terminal 6B, the first gate terminal 6A enters a state of waiting for reception of a signal from the host terminal 3B at the frequency A.

  The third gate terminal 6C receives the signal from the second gate terminal 6B at the frequency C, and transmits the signal at the frequency D to the host terminal 3B as a signal obtained by adding the opening / closing information of the third gate terminal 6C to the signal. At the same time, the same signal is sent as a reply to the third gate terminal 6C. Then, at the frequency C, a reply is awaited from the second gate terminal 6B. On the other hand, when the second gate terminal 6B receives a reply from the third gate terminal 6C, the second gate terminal 6B enters a reception waiting state at the frequency B.

  After receiving the signal from the third gate terminal 6C at the frequency D, the host terminal 3B transmits (replies) the signal at the frequency A to the third gate terminal 6C to complete the communication.

  When the third gate terminal 6C receives a reply from the host terminal 3B at the frequency A, the third gate terminal 6C enters a state of waiting for reception at the frequency C.

  In addition, since address information is added to the signals transmitted from the host terminal 3B and the gate terminals 6A to 6C, the host terminal 3B and the gate terminals 6A to 6C receive signals of frequencies waiting for reception. However, if the addresses do not match, the operation is not performed and the received signal is discarded.

  In addition, when an abnormality occurs in the gate terminals 6A to 6C, the gate terminals 6A to 6C in which the abnormality has occurred add abnormality information to the information collection signal instead of the opening / closing information, and an abnormality occurs in the host terminal 3B. To inform.

  Specifically, the abnormalities are as follows: (i) Locking control is performed but locking is not possible, (ii) Unlocking control is performed but unlocking is not possible, (iii) It is monitored for four types of door opening abnormalities with the doors left open, and (iv) locked doors, but door breaking abnormalities that cause the doors to open.

Then, the flow of the process which detects each said abnormality with CPU of gate terminal 6A-6C is demonstrated. It should be noted that the determination of locking abnormality and unlocking abnormality is started by the input of the locking signal / unlocking signal from the electric locks 4A to 4C or the card readers 5A to 5C. Although it can be performed at regular time intervals by a command from the terminal 3B, it can also be performed arbitrarily by the system administrator.
(i) Locking Abnormality As shown in FIG. 5, when control is started by the input of a locking signal from the upper management device 3A or the card readers 5A to 5C for controlling the locking of the electric locks 4A to 4C, locking control is started (step S11). ), It is determined whether locking has been performed (step S12).

  If the lock is performed, it is normal and the process ends. On the other hand, if locking has not been performed, it is determined whether or not M seconds have elapsed (step S13), and if not, processing returns to step S12.

If M seconds have elapsed, it is determined whether the control has been performed N times (step S14). If the control is not performed N times, the process returns to step S11. If the control is performed N times, it is determined that the locking is abnormal (step S15), and the process ends. The reason for determining the elapse of M seconds or N times of control is that locking or unlocking may not be performed immediately, or locking or unlocking may not be possible with a single control.
(ii) Unlocking abnormality As shown in FIG. 6, when starting, the unlocking control is started by the input of the unlocking signal from the upper management device 3A for controlling the locking of the electric locks 4A to 4C or the card readers 5A to 5C. (Step S21), it is determined whether unlocking has been performed (Step S22).

  If unlocking has been performed, it is normal and the process ends. On the other hand, if unlocking has not been performed, it is determined whether or not M seconds have passed (step S23), and if not, the process returns to step S22.

If M seconds have elapsed, it is determined whether or not the control has been performed N times (step S24). If the control is not performed N times, the process returns to step S21. If the control is performed N times, it is determined that the locking is abnormal (step S25), and the process ends.
(iii) Door Opening Abnormality As shown in FIG. 7, when starting, it is determined whether or not the door is closed (step S31).

  If it is in the closed state, it is normal and the process is terminated. On the other hand, if it is not in the closed state, it is determined whether or not M seconds have passed (step S32). If not, the process returns to step S31.

If M seconds have elapsed, it is determined that the opening is abnormal (step S33), and the process ends.
(iv) Door Breaking Abnormality As shown in FIG. 8, when starting, it is determined whether or not the door is locked (step S41).

  If it is locked, the process ends as it is. On the other hand, if it is not locked, it is determined whether or not the door is closed (step S42). If it is not in the closed state, it is considered that the door has been destroyed. Therefore, it is determined that the door is broken abnormally (step S43), and the process ends.

  Each of the gate terminals 6A to 6C receives all signals from the upper management device 3A or the card readers 5A to 5C for controlling the locking of the electric locks 4A to 4C. It is not necessary to have a means for judging the abnormality, and it is possible to have a construction having an abnormality judging means for judging at least one abnormality.
