In the present embodiment, the light emitting element 21 is formed by an LED that emits infrared light. In the present embodiment, the light receiving element 22 is formed of a photodiode. The number of light emitting elements 21 and light receiving elements 22 is the same. A pair of the light emitting element 21 and the light receiving element 22 that receives light emitted from the light emitting element 21 may be referred to as a light shielding sensor. In the present embodiment, a plurality of light shielding sensors are arranged in a straight line.

  In FIG. 1, the plurality of sensor units 18 are arranged at positions that do not overlap each other along the passage direction A-A ′ when viewed in plan from above. In other words, the light beams coming out of the light emitting element 21 in the sensor unit 18 and received by the light receiving element 22 in the other sensor unit 18 are spaced apart from each other in the direction along the path direction AA ′ in plan view. Preferably, they are provided at regular intervals. The interval between the plurality of light beams, and hence the arrangement interval of the plurality of light emitting elements 21, is set to about 150 mm.

  A main control device 23 as a first control means as a main control device is provided inside the casing 4 constituting the main machine 2. A slave control board 24 as second control means as a slave control device is provided inside the housing 5 constituting the slave 3. The main control device 23 is configured by a computer, and includes a CPU (Central Processing Unit) 27 and a memory 28 connected to each other by a bus line 26. The memory 28 is a memory including a mechanical memory such as a hard disk and a semiconductor memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The memory 28 includes program software for realizing the management performed by the entrance / exit management gate device 1, a file area for storing various files, a memory area for storing various data, and the like. ing.

  The display unit 11 and the card reader / writer 13 on the main machine 2 side shown in FIG. 1 are connected to the CPU 27 via the bus line 26 in FIG. Each of a door driving device 32 that drives the door 8, a light emission driving circuit 29 that drives the light emitting element 21, and a light receiving circuit 31 connected to the light receiving element 22 is connected to the CPU 27 via the bus line 26. The door drive device 32 has, for example, a configuration in which a speed reducer-integrated pulse motor is directly connected to the rotation shaft of the door 8. A communication unit 34 is connected to the CPU 27 via the bus line 26. The communication unit 34 is connected to a management computer (host computer) 37 via a network 36.

  In the present embodiment, the slave control board 24 on the slave 3 side is configured by a logic circuit. That is, the slave control board 24 is configured as a simpler control unit than the main controller 23. However, the slave control board 24 may be configured by a computer in the same manner as the main controller 23. The display unit 11 and the card reader / writer 13 on the slave device 3 side shown in FIG. 1 are connected to the slave device control board 24 in FIG. Further, a door driving device 33 for driving the door 9, a light emission driving circuit 29 for driving the light emitting element 21, and a light receiving circuit 31 connected to the light receiving element 22 are connected to the slave control board 24. The door drive device 33 has a configuration in which, for example, a speed reducer-integrated pulse motor is directly connected to the rotation shaft of the door 9.

  The light emission drive circuits 29 on the main machine 2 side and the slave machine 3 side are connected to the respective light emitting elements 21 to control infrared light emission of the light emitting elements 21. Specifically, the timing of the emission (on) and non-emission (off) of the emitted infrared light is controlled. More specifically, as shown in FIG. 3, for example, infrared light is modulated into a pulse signal based on a binary (“0 (zero)” and “1”) serial data signal that fits in about 2 bytes. Control. For this reason, the light emission driving circuit 29 includes an oscillation circuit and a modulation circuit.

  The light emitted from the light emitting element 21 functions as both a light amount signal for detecting a person as an object and a pulse signal for performing information communication. Information used for communication is a command or data. The data is, for example, card information data read from the card by the card reader / writer 13 or data to be written to the card.

The command is preset as an instruction corresponding to the following operation, for example.
(1) Start of modulated light emission of the light emitting element 21;
(2) Start of reading and writing of card information (ID number, etc.) by the card reader / writer 13,
(3) opening doors 8 and 9;
(4) Close the doors 8 and 9.

  The command is represented by a binary number having a predetermined bit number (8-bit number), for example. In communication, when a command is transmitted from the master unit 2 or the slave unit 3, the slave unit 3 or the master unit 2 that has received the command immediately returns a response.

  In the present embodiment, since there is no signal synchronized between the light emitting side and the light receiving side, communication is performed by serial communication using the start-stop synchronization method. In order to realize this start-stop synchronization method, as shown in FIG. 3, a start pulse is inserted at the beginning of the infrared pulse and a stop pulse is inserted at the end. The data signal to be placed on the infrared rays is data transmitted bidirectionally between the main control device 23 in the main unit 2 and the sub unit control board 24 in the sub unit 3. In the present embodiment, the operation on the main device 2 side and the operation on the slave device 3 side are set to be performed in synchronization with each other by wireless communication using the light emitting element 21 and the light receiving element 22.

  Since the data required for the control of the slave unit 3 in FIG. 2 is about 2 bytes, the communication speed is 2400 bps, which is practical. The reaction speed of the light emitting element 21 and the light receiving element 22 used in the present embodiment is a reaction speed such that the communication speed when these are used as communication elements is 10 kbps or higher. Therefore, sufficient communication can be performed using the light emitting element 21 and the light receiving element 22.

  FIG. 4 shows the entrance / exit management gate device 1 of FIG. 1 as viewed from above. Light emitted from the light emitting element 21 on the main unit 2 side and the light emitting element 21 on the slave unit 3 side shown in FIG. 2 is transmitted to the opposite casings 4 and 5 as schematically shown by reference numerals B and B ′ in FIG. It progresses alternately toward. Then, when the person 38 travels in a passage that is a space sandwiched between the housing 4 and the housing 5 (travels in the direction of arrow A in the figure), the person 38 shields the light beam, and the corresponding light receiving element 22 The amount of received light decreases and instantaneously becomes 0 (zero). The main control device 23 in FIG. 2 can determine which light receiving element 22 has the person 38 by detecting this light quantity change. Note that the slave control board 24 does not have such a determination function, and if necessary, an output signal related to the amount of light received by the light receiving element 22 in the slave 3 is output from the slave control board 24 and the light emission drive circuit. 29, and transmitted to the main control device 23 in the main unit 2 by infrared wireless communication via the light emitting element 21, and used for determination by the main control device 23.

  As is apparent from FIG. 4, all of the light emitted from the plurality of light emitting elements 21 is not simultaneously shielded by the passing object, that is, the plurality of light emitting elements 21 on the slave unit 3 side and the plurality of light emitting elements 21 on the side of the main unit 2 opposite thereto. The region where the light receiving element 22 is provided along the passage direction AA ′, the plurality of light emitting elements 21 on the main unit 2 side, and the plurality of light receiving elements 22 on the side of the slave unit 3 opposite thereto are in the passage direction AA ′. Is a region that is sufficiently longer than the length along the passage direction AA ′ of the person 38 who is an object. Then, the infrared light carrying the same data signal is emitted from all the light emitting elements 21 on the slave unit 3 side at the same timing, that is, simultaneously, and the infrared data carrying the same data signal from all the light emitting elements 21 on the main machine 2 side. Are emitted at the same timing. The timing of light emission from the light emitting element 21 on the main machine 2 side and light emission from the light emitting element 21 on the slave machine 3 side are controlled to be different timings.

  The region where the light emitting element 21 and the light receiving element 22 are provided is sufficiently longer than the length of the person 38 as described above, and the same data is emitted from the light emitting elements 21 at the same timing. Even if a part of the light emitted from the plurality of light emitting elements 21 is shielded by the person 38, the data can always be transmitted by the other light emitting elements 21, so that accurate communication is always stable without being interrupted by the shading of the person. Can be done. In addition, since the timing of light emission from the slave unit 3 side and the light emission from the master unit 2 side are different, accurate communication can be performed stably without interference of transmitted data.

  An entrance / exit management gate device according to the present invention includes a first control means for transmitting and receiving signals to and from a light emitting element and a light receiving element provided in a first casing, a light emitting element provided in a second casing, And second control means for transmitting and receiving signals to and from the light receiving element. Each of these control means has object detection means for detecting an object (for example, a person) located between the first housing and the second housing based on the output signal of the light receiving element. . Further, the first control means and the second control means have communication means for transmitting information using a light emitting element and a light receiving element. In the present embodiment, the object detection means is realized by the main control device 23 and the light receiving circuit 31 in the main machine 2 of FIG. The communication means includes the main controller 23, the light emission drive circuit 29, and the light receiving circuit 31 in the main unit 2 of FIG. 2 and the slave control board 24, the light emission drive circuit 29, and the light receiving circuit in the slave unit 3. 31.

  Hereinafter, the operation of the entrance / exit management gate device 1 having the above-described configuration will be described based on FIG. 5 with a focus on the functions realized by the main controller 23 of FIG. The CPU 27 in the main controller 23 in FIG. 2 first outputs a signal instructing initial display to the display unit 11 on the main unit 2 side in step S1, and further receives a command signal for initial display from the light emitting element 21 on the main unit 2 side. Make it emit light. Thereby, an appropriate display indicating the initial state is made on the display unit 11 of the main machine 2 and the slave machine 3.

  Next, in step S2, it is checked whether or not an IC card is presented to the card holding unit 12 on the main machine 2 side. If present (YES in step S2), reading of the contents of the IC card is started (step S3). ).

  Next, the CPU 27 reads the contents of the IC card by the card reader / writer 13 on the main unit 2 side in step S3, and further transmits the read data from the communication unit 34 of FIG. 2 to the management computer 37 via the network in step S4. . The management computer 37 determines whether the transmitted data is valid or invalid, further executes a predetermined process for the card, and transmits the determination result and the processing result to the main controller 23. In addition, it is also possible to perform the validity / invalidity determination and the predetermined processing by the main control device 23 itself without using the management computer 37.

  Next, when it is determined that the card is valid, “YES” is determined in the step S5, and a valid display is made on the display unit 11 on the main machine 2 side in a step S6. Further, if necessary, a command signal indicating validity is emitted from the light emitting element 21 on the main machine 2 side, and valid display is also performed on the display unit on the slave machine 3 side.

  Thereafter, in step S7, a door opening signal is transmitted from the main controller 23 to the door driving device 32 on the main machine 2 side, and the door 8 on the main machine 2 side is opened. At the same time, a command signal indicating a door opening signal is emitted from the light emitting element 21 on the main machine 2 side, and the door 9 on the slave machine 3 side is opened by the slave control board 24. As a result, the doors 8 and 9 are opened and the passage can pass. The slave control board 24 that has received the command signal emits a response signal from the light emitting element 21 on the slave 3 side. The opening operation of the door 8 at this time is synchronized between the main machine 2 side and the slave machine 3 side. That is, the door 8 is simultaneously opened on both the main machine 2 side and the slave machine 3 side.

  When the main control device 23 on the main machine 2 side receives the response signal (YES in step S8), the output signals of all the light receiving elements 22 on the main machine 2 side are read in step S9. Then, main controller 23 performs determination processing related to an object, that is, a person in step S10 based on the read data. For example, it is determined according to the program where a person is passing in the passage, whether the person is a person or a baggage, whether a person is accompanied by a plurality of persons, and the like. The determination result may be displayed on the display unit 11. When the person goes out of the light emitting area of the last light emitting element 21, it is determined that the person has passed (YES in step S11), and main controller 23 generates and outputs a door closing signal in step S12.

  The door closing signal is transmitted to the door driving device 32 on the main machine 2 side, and is transmitted as a command signal to the slave unit 3 side by the light emitting element 21 on the master unit 2 side, and is transmitted to the slave unit 3 side by the slave unit control board 24. It is transmitted to the door drive device 33. As a result, the doors 8 and 9 are closed, and the passage of the person is completed. The slave control board 24 emits a response signal from the light emitting element 21 on the slave 3 side in response to the command signal. When main controller 23 receives the response signal in step S13, the process ends.

  The above is the processing when the IC card is presented to the card holding unit 12 on the main unit 2 side in FIG. 1, but unlike this, the IC card is presented to the card holding unit 12 on the slave unit 3 side. In some cases, the light emitting element 21 on the side of the slave unit 3 in FIG. 2 emits a signal to that effect and a card reading data signal (YES in step S14). When main controller 23 receives the signal, a response signal is emitted from light emitting element 21 toward slave unit 3. Further, the card information read on the slave device 3 side is read by the main controller 23 on the master device 2 side in step S3. Subsequent processing is the same as described above.

  As described above, the card data read by the main controller 23 in step S3 is transmitted to the management computer in step S4, and the validity / invalidity determination is made. If it is determined that the card is invalid at this time, NO is determined in step S5, and invalid display is performed on the display unit 11 in step S15.

  As described above, in the present embodiment, specific and detailed control of the operation on the side of the slave unit 3 in FIG. 2 is performed by the slave unit control board 24 in the slave unit 3, and roughly such as ON / OFF or the like. Timing is indicated by a command signal from the main unit 2 side.

  In addition, according to the present embodiment, information is transmitted by infrared communication using the light emitting element 21 and the light receiving element 22 between the master control device 23 on the master machine 2 side and the slave control board 24 on the slave machine 3 side. Therefore, it is no longer necessary to connect the main control device 23 and the slave control board 24 with a cable as in the prior art. As a result, the construction for installing the main machine 2 and the subordinate machine 3 on the installation surface 6 has become very simple.

  Moreover, since infrared communication is realized by using both the light-emitting element 21 and the light-receiving element 22 for detecting an object such as a person, there is no need to newly provide a transmitter and a receiver for wireless communication. Therefore, the configuration is not complicated and the cost is not increased.

  For example, in the above description, the same signal is simultaneously emitted from the plurality of light emitting elements 21 on the main unit 2 side or the plurality of light emitting elements 21 on the side of the slave unit 3 shown in FIG. Instead, the form of communication may be changed in accordance with the movement of an object such as a person. For example, in a state where communication is performed using all of the light emitting elements 21 and the light receiving elements 22, a communication result of the light emitting elements 21 and the light receiving elements 22 that are farthest from the light emitting elements 21 that are shielded from light by an object. May be actively employed. Further, the communication itself is not performed using all the light emitting elements 21, but only the light emitting element 21 that is farthest from the light emitting element 21 that is shielded from light by the object and the light emitting elements that are in the vicinity of the remote light emitting element 21 are used. Communication may be performed.

  In the embodiment shown in FIG. 2, on the main machine 2 side and the slave machine 3 side, the sensor unit 18 having the light emitting element 21 and the light receiving element 22 in a paired state is used to detect an object such as a person. Performed both infrared wireless communication between the main and slave units. However, instead of this, as shown in FIG. 6, the light emitting elements 21 and the light receiving elements 22 that are not in a unit state are arranged alternately facing the path in both the main unit 2 and the sub unit 3. Anyway.
