Therefore, in recent years, EMS is often introduced into various buildings such as buildings, commercial facilities, and houses. Yes. In EMS, since it is necessary to control a device to be managed, it is indispensable to acquire information on the device to be managed and notify the device to be managed. Therefore, in EMS, it is necessary to mount a communication function on a device to be managed.

  When EMS is introduced, there is an increasing need to mount a means that can perform cheaper and more reliable communication, particularly in lighting equipment (to be managed).

  Conventionally, a technique has been adopted in which a lighting device is connected to a dedicated line or the like, and control information is transmitted to the lighting device by wired communication to control the lighting device. However, this method has a problem that enormous wiring work costs are required to control each lighting device one by one.

<1.1: Logical Configuration of Wireless Communication Device>
FIG. 1 is a schematic configuration diagram of a wireless communication device 100 according to the first embodiment.

  The antenna element portion 11 is formed of a conductor, and is formed to constitute a loop antenna, for example, as shown in FIG. The antenna element portion 11 has a first connection end portion 11a and a second connection end portion 11b, which are connection end portions to be electrically connected to the wireless communication unit. As shown in FIG. 1, the first connection end 11a of the antenna element portion 11 is connected to the antenna-side first electrode 12a. Further, the second connection end portion 11b of the antenna element portion 11 is connected to the antenna-side second electrode 12b as shown in FIG. The antenna element unit 11 is not limited to a loop antenna, and may be formed so as to constitute another antenna (for example, a dipole antenna).

  The antenna-side first electrode 12a is formed of a conductor, and forms an electronic circuit (antenna circuit) by capacitive coupling together with the wireless communication unit-side first electrode 21a of the wireless communication unit 2.

  The antenna-side second electrode 12b is formed of a conductor, and forms an electronic circuit (antenna circuit) by capacitive coupling together with the wireless communication unit-side second electrode 21b of the wireless communication unit 2.

  The radio communication unit side second electrode 21b is formed of a conductor, and forms an electronic circuit (antenna circuit) together with the antenna side second electrode 12b of the antenna unit 1 by capacitive coupling.

  The matching unit 21 includes a circuit (impedance adjustment circuit) that performs impedance adjustment. The impedance adjustment circuit of the matching unit 21 is connected to the antenna element unit 11 of the antenna unit 1 and performs impedance adjustment. When the antenna unit 1 functions as a transmission / reception antenna, the matching unit 21 may include a transmission impedance adjustment circuit and a reception impedance adjustment circuit. When the antenna unit 1 functions as a transmission / reception antenna, the matching unit 21 may include a circuit in which a transmission impedance adjustment circuit and a reception impedance adjustment circuit are shared.

  When the antenna unit 1 functions as a reception antenna, the RF unit 22 operates an antenna reception processing unit (for example, an antenna reception processing circuit) and performs an impedance adjustment signal output from the matching unit 21. Then, antenna reception processing (for example, processing including RF demodulation processing) is executed. Then, the RF unit 22 outputs a signal (information) acquired by antenna reception processing (for example, RF demodulation processing) to the communication control unit 23.

  On the other hand, when the antenna unit 1 functions as a transmission antenna, the RF unit 22 operates an antenna transmission processing unit (for example, an antenna transmission processing circuit). For example, the signal (information) output from the communication control unit 23 is RF-modulated, and the RF-modulated signal is output to the matching unit 21.

First, a case where a vertical flat plate type connection unit is applied as a connection unit of the wireless communication device 100 will be described with reference to FIGS.

  FIG. 2 is a diagram for explaining a case where a vertical flat plate type connection unit is applied as the connection unit of the wireless communication apparatus 100. Specifically, the upper diagram of FIG. 2 is a plan view of the antenna unit 1 (part) and the wireless communication unit 2, and the lower diagram of FIG. 2 is a schematic diagram of the A1-A1 line in the upper diagram of FIG. It is sectional drawing. A schematic cross-sectional view taken along line A2-A2 in the upper diagram of FIG. 2 is the same as the lower diagram of FIG.

  In FIG. 2, the antenna unit 1 (part) and the wireless communication unit 2 are illustrated separately.

  FIG. 3 is a view similar to FIG. 2, and shows the antenna unit 1 (part) and the radio communication unit 2 adjacent to each other. That is, FIG. 3 is a diagram when the antenna unit 1 and the wireless communication unit 2 are electrically connected.

  4 is a diagram in which a schematic cross-sectional view taken along line B1-B1 in FIG. 3 is added.

  As shown in FIGS. 2 to 4, the antenna-side first electrode 12a, the antenna-side second electrode 12b, the radio communication unit-side first electrode 21a, and the radio communication unit-side second electrode 21b have the same shape and are flat plates. It is formed from a shaped conductor.

  The substrate 1B of the antenna unit 1 and the substrate 2B of the wireless communication unit 2 are substrates made of an insulator, and the material thereof is, for example, ABS resin.

  As shown in the lower diagram of FIG. 2, the substrate 1 </ b> B of the antenna unit 1 has a wall 1 </ b> Ba extending at the end in the direction perpendicular to the surface of the substrate 1 </ b> B. As shown in FIG. 2, the antenna-side first electrode 12 a is installed on the antenna element part 11 side of the wall part 1 Ba. And the antenna side 1st electrode 12a is connected with the edge part of the antenna element part 11, for example in the edge part by the side of the board | substrate 1B, as shown in FIG.

  The antenna-side second electrode 12b is also arranged and connected in the same manner as described above.

  As shown in the lower diagram of FIG. 2, the substrate 2B of the wireless communication unit 2 has a wall 2Ba extending at the end in the direction perpendicular to the surface of the substrate 2B. As shown in FIG. 2, on the side of the circuit portion C2 of the wall 2Ba (for example, the circuit portion C2 is an integrated circuit including the matching unit 21, the RF unit 22, and the communication control unit 23), wireless communication is performed. The part side 1st electrode 21a is installed. Then, for example, as shown in FIG. 2, the first electrode 21a on the wireless communication unit side is connected to a conductor lead pattern L2a for electrical connection with the circuit unit C2 at the end on the substrate 2B side. , And electrically connected to the circuit portion C2 through the conductor lead pattern L2a and L2b. As shown in FIG. 2, the circuit unit C2 is installed on the substrate P2 for the wireless communication circuit. In FIG. 2, it is assumed that the circuit unit C2 is one integrated circuit (LSI chip) including the matching unit 21, the RF unit 22, and the communication control unit 23. However, the present invention is not limited to this. Rather, the circuit unit C2 includes a peripheral circuit made of discrete components and one or a plurality of integrated circuits that form the matching unit 21, the RF unit 22, and the communication control unit 23 on the substrate P2 for the wireless communication circuit. It may be configured.

  Further, part or all of the components (wireless communication unit side first electrode 21a, conductor lead pattern, wireless communication circuit substrate P2, circuit unit C2, etc.) arranged on the substrate 2B are the same as those of the substrate 2B. You may make it cover with the substance (for example, ABS resin) of a material. Thereby, a part or all of the components arranged on the substrate 2B are arranged in the same material (for example, ABS resin) as the substrate 2B (the same material (for example, ABS) as the substrate 2B). Resin) is disposed in the housing), and it is possible to prevent water droplets, dust, dust and the like from entering from the outside.

  The wireless communication unit side second electrode 21b is also arranged and connected in the same manner as described above.

  As shown in FIGS. 3 and 4, the circuit board 1 </ b> B of the antenna unit 1 and the board 2 </ b> B of the wireless communication unit 2 are arranged so as to be in contact with each other, whereby an electronic circuit (antenna circuit) is formed by capacitive coupling. It is formed.

  That is, as shown in FIGS. 3 and 4, the same, flat plate-like antenna-side first electrode 12 a and radio communication unit-side first electrode 21 a are arranged in parallel as shown in FIGS. 3 and 4. Thus, a circuit equivalent to a capacitor is formed. Thereby, an electronic circuit (antenna circuit) is formed between the antenna unit 1 and the wireless communication unit 2 by capacitive coupling.

As shown in FIGS. 3 and 4, the antenna-side first electrode 12a and the wireless communication unit-side first electrode 21a are arranged with the substrate 1B and the substrate 2B interposed therebetween. The dielectric constant of the material forming the substrate 1B and the substrate 2B is ε, and the antenna-side first electrode 12a and the wireless communication unit side first electrode on the side where the antenna-side first electrode 12a and the wireless communication unit-side first electrode 21a face each other. Assuming that the surface area of each electrode 21a is S and the distance between the antenna-side first electrode 12a and the radio communication unit side first electrode 21a is d, the antenna-side first electrode 12a and the radio communication unit side The capacitance (capacitance value) C between the first electrode 21a is
C = ε × S / d
It becomes.

  The same applies to the antenna-side second electrode 12b and the radio communication unit-side second electrode 21b.

  The capacitance value C determined as described above may be determined by the antenna unit 1 and the wireless communication unit 2 according to the frequency of the antenna signal to be transmitted and received.

For example, the frequency of the antenna signal desired to be transmitted / received (or the center frequency of the frequency band of the antenna signal desired to be transmitted / received) is fc [Hz], and between the antenna-side first electrode 12a and the wireless communication unit-side first electrode 21a (or the antenna). Xc (= 1 / (2π × fc × C)) when the capacitive reactance between the second electrode 12b on the side and the second electrode 21b on the wireless communication unit side)
Xc <500 [Ω]
Is preferable. further,
Xc <300 [Ω]
Is more preferable.

  For example, when the frequency of a signal to be transmitted / received to the antenna is 1 [GHz], the impedance Zc (or capacitive reactance Xc) between the antenna-side first electrode 12a and the radio communication unit-side first electrode 21a at the frequency is 40 [Ω. You may make it become the grade.

  In order to obtain the desired capacitive reactance Xc and capacitance value C, for example, between the antenna-side first electrode 12a and the wireless communication unit-side first electrode 21a (or the antenna-side second electrode 12b and the wireless communication unit-side first The material of the substrate sandwiched between the two electrodes 21b) may be replaced with one having a higher dielectric constant. Further, a dielectric may be sandwiched between the antenna-side first electrode 12a and the wireless communication unit-side first electrode 21a (or between the antenna-side second electrode 12b and the wireless communication unit-side second electrode 21b).

  Further, the antenna-side first electrode 12a and / or the radio communication unit are set so that the capacitance (capacitance value) C between the antenna-side first electrode 12a and the radio communication unit-side first electrode 21a becomes a desired value. The shape, width, surface area, etc. of the first side electrode 21a may be determined.

  As described above, when a vertical flat plate type connection part is applied as the connection part of the wireless communication device 100, the antenna side second electrode 12b is provided between the antenna side first electrode 12a and the wireless communication part side first electrode 21a.

Prepare. The network N1 is, for example, a wired network using a dedicated line or a network (for example, a power line carrier communication network (PLC network)) that performs communication by modulating and superimposing a signal on a power line.

  Further, as shown in FIG. 19, the illumination control system 3000 is connected to a detachable wireless communication module WM11 and a detachable wireless communication module WM12 that are connected to the first slave device S1 by a wireless communication network W1. And an illumination module LM12.

And an illumination module LM22.

  The detachable wireless communication modules WM11, WM12, WM21, and WM22 are the same as the wireless communication unit 2 of the second embodiment.

  Further, as shown in FIG. 19, the illumination control system 3000 includes an illuminance sensor SS31 connected to the third slave device S3 via a wireless communication network W3, and a human sensor SS32.

  In the case of FIG. 19, the lighting control system 3000 includes one master device and three slave devices, but the lighting control system 3000 is not limited to this configuration, and a plurality of master devices. And a plurality of slave devices.

  The detachable wireless communication modules WM11, WM12, WM21, and WM22 are the same as the wireless communication unit 2 (wireless communication module) described in the above embodiment, and are detachable from the illumination module by a connector or the like. .

  The illumination modules LM11, LM12, LM21, and LM22 are the same as the illumination module 10 described in the above embodiment. In addition, about the power supply part 3, illustration is abbreviate | omitted.

  For example, in the illumination control system 3000, the illuminance detected by the illuminance sensor SS31 is in a low (dark) state, the human sensor SS32 detects a person, and the plurality of light emitting elements of the illumination module LM11 are turned off. The control for turning on the light will be described below.

  First, the illuminance sensor SS31 transmits a signal including information indicating that the illuminance detected by the illuminance sensor SS31 is low (dark) to the third slave device S3 via the wireless communication network W3.

  The third slave device S3 transmits a signal including information acquired from the illuminance sensor SS31 via the wireless communication network W3 to the master device M1 via the wired network N1.

  The master device M1 acquires information about the illuminance detected by the illuminance sensor SS31 received via the wired network N1 from the third slave device S3, and holds the information.

  Next, when the human sensor SS32 detects a person, the human sensor SS32 transmits a signal including information indicating that the person is detected to the third slave device S3 via the wireless communication network W3.

  The third slave device S3 transmits information received from the human sensor SS32 via the wireless communication network W3 (information indicating that a person has been detected) to the master device M1 via the wired network N1.

  The master device M1 acquires information indicating that a person has been detected by the human sensor SS32 based on a signal received from the third slave device S3 via the wired network N1. And the master apparatus M1 transmits the signal which instruct | indicates lighting of the several light emitting element of module LM11 for illumination to 1st slave apparatus S1 via the wired network N1.

  The first slave device S1 receives a signal transmitted from the master device M1 via the wired network N1, and transmits the received signal to the removable wireless communication module WM11 via the wireless communication network W1.

  The removable wireless communication module WM11 receives a signal from the first slave device S1 via the wireless communication network W1. Specifically, the wireless signal from the first slave device S1 is received by operating the circuit of the illumination module LM11 as a reception antenna. Then, processing by the matching unit 21 (or 21A) and the RF unit 22 (or 22A) of the removable wireless communication module WM11 is performed on the received signal. Thereby, the communication control unit 23 (or 23A) of the removable wireless communication module WM11 acquires a signal instructing lighting of the plurality of light emitting elements of the illumination module LM11. The communication control unit 23 (or 23A) then supplies a voltage supplied from the power supply unit 3 to the illumination module 10 to a predetermined voltage (predetermined adjustment) that can turn on the light emitting elements LE1 to LEn of the illumination module 10. A control signal Ctl for instructing to be a voltage for realizing the light rate is output to the power supply unit 3.

  As a result, the plurality of light emitting elements of the illumination module LM11 are turned on.

  Note that the communication control unit 23 (or 23A) of the detachable wireless communication module WM11 outputs a signal including information on power consumed by lighting of the plurality of light emitting elements of the illumination module LM11 to the illumination module LM11. By operating the circuit as a transmission antenna, it may be controlled to be transmitted to the first slave device S1 via the wireless communication network W1.

  In this case, the first slave device S1 receives the signal transmitted from the removable wireless communication module WM11, and transmits the received signal to the master device M1 via the wired network N1.

  And the master apparatus M1 can grasp | ascertain the electric energy consumed because the module LM11 for illumination is lighting from the signal received via the wired network N1 from 1st slave apparatus S1.

  The illumination control system 3000 can perform control such as turning off unnecessary lighting in order to grasp the power consumption acquired from each slave device and realize energy saving by performing such processing.

  Furthermore, as shown in FIG. 19, the master device M1 may be connected to the host system H1 via the network N2, and the information collected by the master device M1 may be transmitted to the host system H1. The host system H1 may instruct the master apparatus M1 to perform predetermined control based on the collected information.

  In the above description, the detachable wireless communication module and the illumination module have been described for the case where the wireless communication is performed only with the slave device, but the present invention is not limited to this, and the detachable wireless communication module and the illumination module are not limited thereto. You may make it communicate by radio | wireless. In this case, wireless communication may be performed by a wireless multi-hop communication method.

  As described above, in the illumination control system 3000, the illumination control system can be configured using the removable wireless communication module and the illumination module corresponding to the illumination device 200 of the second embodiment. In the lighting control system 3000, only the slave device needs to have the communication functions of both the wired network and the wireless communication network, and the removable wireless communication module and the lighting module need only have the wireless communication function. . Thereby, in the lighting control system 3000, the total cost can be reduced when the system is constructed.

  Furthermore, since the wireless communication module can be attached to and detached from the illumination module, the cost of the illumination module can be reduced. And since it is only necessary to load a detachable wireless communication module only to the illumination module to which a wireless communication function is to be added, it is possible to easily construct the illumination control system 3000 having flexibility and high expandability. Can do.

  Further, since the removable wireless communication module (wireless communication unit) does not have a portion in direct contact with the metal terminal (conductor portion), it maintains a good use state without causing contact failure for a long period of time. be able to. For this reason, in the illumination control system 3000, the cost and labor required for maintenance, replacement, etc. of the wireless communication module can be significantly reduced.
