[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring and control system.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
The operation terminal 92 having W and the control terminal 93 for controlling the lighting load L are branched and connected to a two-wire signal line Ls, and the operation terminal 92 and the control terminal are connected through the signal line Ls. A remote monitoring and control system having a configuration in which a transmission control device 93 is connected to a transmission control device 91 has been proposed.

In such a remote monitoring and control system, each transmission terminal 91 transmits a transmission signal Vs having a format as shown in FIG.
Data is exchanged with the second and the third. That is, the transmission signal Vs includes a start pulse ST indicating the start of signal transmission,
Mode data MD indicating the mode of the signal, terminals 92 and 9
Address data AD for individually recognizing 3, control data CD indicating the control contents for the lighting load L, and error correction code C such as checksum data for detecting a transmission error.
S, a bipolar (± 24 V) time-division multiplexed signal including a signal return period WT for setting a return period from the terminals 92 and 93, and data is transmitted by pulse width modulation (FIG. 16 (b)). Each terminal 92, 93
When the address included in the address data AD of the transmission signal Vs received via the signal line Ls matches an address set in advance, the transmission signal Vs
s of control data CD and the transmission signal Vs
The monitoring data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate low impedance) in synchronization with the signal return period WT.

On the other hand, the transmission control device 91 is provided with dummy signal transmitting means and interrupt processing means. The dummy signal transmitting means always transmits the transmission signal Vs in which the mode data MD is changed to the dummy mode and the address data AD is cyclically changed at a constant time interval. Further, in the interrupt processing means, the operation terminal 92 synchronizes with the start pulse ST of the transmission signal Vs in the dummy mode.
When an interrupt signal Vi as shown in FIG.
By transmitting the mode data MD of the transmission signal Vs in the address confirmation mode, the operation terminal 92 is accessed by a plurality of units, and the address data is returned from the operation terminal 92 having generated the interrupt signal Vi during the signal return period WT. The monitoring data is returned from the operating terminal 92 which has generated the interrupt signal Vi by accessing using the acquired address.

When the transmission control device 91 receives the monitoring data from the operation terminal device 92 as described above, the transmission control device 91 transmits the control data CD to the control terminal device 93 in which the correspondence by address is set in advance. And transmits the transmission signal Vs to the signal line Ls. That is, the lighting load L connected to the designated control terminal 93 is turned on / off according to the control data CD,
It is dimmed. Here, the operation terminal 92
And the power supply for operation of the control terminal 93 is the transmission signal V
s is obtained by full-wave rectification. For dimming control, a controllable terminal 93 capable of dimming control is used, and a dimming level is instructed by control data.

[0006] A wireless relay terminal 94 is also connected to the signal line Ls.
4, a plurality of wireless receivers Yb are branched and connected via a two-wire wireless signal line Lw. Each wireless receiver Yb receives a wireless signal using infrared rays as a medium from the wireless transmitter Xb, and transfers the wireless signal to the wireless relay terminal 94 via the wireless signal line Lw.

That is, the wireless transmitter Xb has the same switch SW as the operation terminal 92, and the switch SW
Is operated, a wireless signal including address data and monitoring data is transmitted. This wireless signal is converted into a baseband signal by the wireless receiver Yb and transferred to the wireless relay terminal 94. The wireless relay terminal 94 uses the address data transferred from the wireless transmitter Xb to transmit the transmission control device 9
1 and transmits the monitoring data transferred from the wireless transmitter Xb to the transmission control device 91.

[0008] By using the wireless relay terminal 94 in this manner, wireless load control by the wireless transmitter Xb can be performed, and the wireless relay terminal 9 can be controlled.
4 is supplied from a commercial power supply (100V AC) and this power is transmitted to the wireless receiver Yb, so that the wireless receiver Yb can be added without increasing the output current capacity of the transmission control device 91. That is,
The transmission control device 91 controls the operation terminal 91, the control terminal 92, and the wireless relay terminal 94 according to the transmission signal Vs.
Since the power is supplied to the wireless receiver Yb, when the power is also supplied to the wireless receiver Yb, the current flowing through the signal line Ls increases, but the power is supplied from the wireless relay terminal 94 to the wireless receiver Yb. Therefore, regardless of the number of wireless receivers Yb, the transmission control device 91 does not need to increase the supply power.

[0009]

The frequency range of a carrier of a wireless signal using infrared light as a medium as described above is conventionally determined. On the other hand, recently, inverter devices have been frequently used because of advantages such as small size and high power factor as a lighting circuit of a lighting load, and high frequency infrared rays have been generated from the lighting load. I have. Here, since the frequency of the infrared light generated from the lighting load using the inverter device in the lighting circuit and the frequency of the carrier of the wireless signal are close to each other, the infrared light generated from the lighting load is not suitable for the wireless signal. A problem has arisen that noise components are generated, and as a result, transmission of wireless signals is hindered. That is, there may be a disadvantage that the lighting load L cannot be controlled by operating the wireless transmitter Xb.

Therefore, conventionally, the installation condition is determined so that the illumination load L and the wireless receiver Yb are installed at a distance of 1.5 m or more. However, when the illumination load L and the wireless receiver Yb are actually used in an office space, etc. Therefore, since the installation of the lighting load L is prioritized, it is often impossible to install the wireless receiver Yb so as to satisfy the above conditions, and a system using a wireless signal cannot be constructed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a wireless receiver close to a lighting load without any particular restrictions on installation conditions even when a lighting load using an inverter device is used. It is an object of the present invention to provide a remote monitoring control system in which a remote monitoring control system can be arranged.

In this configuration, a wireless signal based on light and a wireless signal based on radio waves can be used on the same wireless signal line, and both light and radio waves can be used according to use conditions without complicating the signal line system. It becomes possible to do. In other words, light can be used when the reception area of the wireless receiver is to be reduced, and radio waves can be used when the influence of the lighting load is large or when the reception area of the wireless receiver is to be increased. Therefore, the degree of freedom in design increases. Moreover, it is possible to cope with both wireless signals of radio waves and light simply by replacing the wireless receiver installed in advance, so that specification changes are facilitated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Basic Configuration 1) FIG. 1 shows a basic configuration. The transmission control device 91, the operation terminal device 92 (not shown in FIG. 1), and the control terminal device 93 are the same as those of the conventional remote monitoring and control system.
A two-wire signal line Ls connected to the transmission control device 91 includes:
The operation terminal 92 and the control terminal 93 are branched and connected. The transmission control device 91 is supplied with power from a commercial power supply, and the control terminal 93 has a built-in latching relay for turning on and off the load. A wireless relay terminal 94 is also connected to the signal line Ls, and the operation of the wireless relay terminal 94 with the transmission control device 91 is the same as that of a conventional wireless relay terminal 94 using infrared rays for wireless signals.

The transmission control device 91, the control terminal 93, and the wireless relay terminal 94 are housed in a control panel 90 and have a shape and dimensions for mounting the panel. In particular, the control terminal 93 has a body having the same shape and the same dimensions as those of the relay for panel mounting. A two-wire wireless signal line Lw is connected to the wireless relay terminal 94, and a wireless receiver Ya is branched and connected to the wireless signal line Ls. Here, while the conventional wireless receiver Ya was to receive wireless signals infrared, fundamental structure of FIG. 1
Shows the one that receives wireless radio signals
You. Therefore, the wireless transmitter Xa used together with the wireless receiver Ya also transmits a wireless signal using radio waves as a medium.

By the way, when light is used for a wireless signal, the wireless transmitter Xa must be arranged at a position where the wireless receiver Ya can be seen, but when radio waves are used for the wireless signal, the wireless signal passes through an obstacle. It has the advantage that it is less susceptible to obstacles because it moves around. On the other hand, the transmission range of the wireless signal is difficult to limit, and the wireless signal may be transmitted over an unnecessary wide range. For example, when a plurality of different systems (that is, a plurality of remote monitoring and control systems having different transmission control devices 91) are arranged relatively close to each other, a wireless signal is transmitted to a system which is not to be controlled. . In order to prevent confusion in load control even in such a case, a transmitter code is set for each wireless transmitter Xa, and the transmitter code is transmitted as a wireless signal along with address data and monitoring data. It is. Transmitter code is wireless receiver Y
a, the transmitter code received through the wireless signal line Lw is transmitted to the wireless relay terminal 94 through the wireless relay terminal 94.
When it matches the transmitter code registered in advance, the address data and the monitoring data are received. If the transmitter codes do not match, it is determined that the signal is a wireless signal from another system, and the address data and monitoring data are invalidated.

A wireless signal is used for setting the transmitter code. That is, the wireless transmitter Xa can select an operation mode in which the transmitter code is registered in the wireless relay terminal 94. When this operation mode is selected, a wireless signal having a dedicated format is transmitted, and the wireless relay terminal 94 Then, the transmitter code is received by a protocol corresponding to this format, and the received transmitter code is stored in a built-in memory. The transmitter code stored in the memory in this way is used in subsequent operations.

The wireless receiver Ya basically has the configuration shown in FIG.
The circuit configuration shown in FIG. That is, an antenna 11 for receiving a wireless signal is provided. A receiving circuit 12 demodulates a wireless signal to extract address data and monitoring data, and then connects to a wireless signal line Lw connected via a terminal 15 in a signal converting circuit 13. The signal is converted to a current mode signal for transmission. Here, the wireless signal line Lw
Instead of the current mode signal, a signal for changing the line voltage may be transmitted. The wireless signal line Lw is supplied with power from the wireless relay terminal 94, and the wireless receiver Ya supplies power obtained from the wireless signal line Lw through the power supply circuit 14 to the internal circuit. In short, the wireless receiver Ya transmits the data to the wireless relay terminal 94 as it is simply by changing the signal form of the wireless signal.

The wireless receiver Ya is installed mainly near the ceiling to widen the receiving area. Therefore, there are two types: one that is exposed to the ceiling surface and one that is arranged inside the ceiling. The wireless receiver Ya exposed and installed on the ceiling surface, as shown in FIG.
A vessel 2 having a disk-shaped flange portion 21 and a body 22 integrally provided on one surface side of the flange portion 21 in the thickness direction.
0a. Further, a decorative cover 23 is detachably connected to the flange portion 21 by concave and convex engagement. The flange portion 21 is connected to an embedded box such as a switch box or an outlet box used for a ready-made embedded wiring device by using a box screw. A pair of mounting holes 24 are provided in accordance with the mounting pitch. In addition, a groove 25 for attaching the clip metal at a portion different from the mounting hole 24 and an operation hole 26 for operating the clip metal are formed. The holding member is a well-known one. The holding member is fixed by engaging a lower portion of a column having a substantially U-shaped cross section with the groove portion 25 and screwing with a tightening screw inserted into the column. Is raised and lowered with the rotation of the tightening screw, so that the flange 21
And the distance between the clip and the clip can be changed. Here, the tightening screw can be rotated by inserting a driver or the like through the operation hole 26.

Therefore, the body 22 is inserted into a hole formed in a ceiling board formed of a gypsum board or the like while the sandwiching piece is separated from the flange portion 21, and the flange portion 2 is inserted.
When the clamp 1 is brought into contact with the ceiling surface and the fastening screw is rotated to bring the holding piece closer to the flange portion 22, the container body 20a is fixed to the ceiling in such a manner that the ceiling board is held between the flange portion 21 and the holding piece. can do. Thereafter, if the decorative cover 23 is attached, the fastening screw and the like can be covered. In addition, the antenna 11 can be built in the body 20a. However, by projecting the antenna 11 from the center of the lower surface of the body 20a, a wireless receiver Ya applied to a wireless signal using a radio wave as a medium can be used. This makes it easy to understand that the antenna 11 has a high gain, and the receiving area can be widened.

On the other hand, as shown in FIG. 4, the wireless receiver Ya disposed in the ceiling is a rectangular parallelepiped body 20b.
And a pair of mounting pieces 27 projecting up and down of the container 20b. The mounting piece 27 is an elastic body (metal plate) having flexibility in a direction perpendicular to the plane of the drawing.
In each of the mounting pieces 27, an insertion hole 28 is formed. Generally, in an office building or the like, a ceiling bar is suspended by hanging bolts hanging from a ceiling slab, and a ceiling panel is constructed by attaching a ceiling panel to the ceiling bar. Therefore, as shown in FIG. Piece 2
7, the container 20 b can be attached to the suspension bolt 29 by the elasticity of the attachment piece 27. By disposing the container 20b in the ceiling using the suspension bolts 29 as described above, the container 20b is not exposed to the room, and the beauty of the ceiling is not spoiled. Moreover, since the wireless signal is a radio wave, the wireless signal can be received even if a ceiling panel exists between the wireless transmitter Xa.

As shown in FIG. 5, the wireless transmitter Xa includes a signal processing unit 30 composed of a microcomputer, and is connected to four switches SW similarly to the operation terminal 92. Also, a storage unit 31 composed of an EEPROM storing address data corresponding to each switch SW.
Is provided. The storage unit 31 stores not only the address data but also the transmitter code. The data stored in the storage unit 31 is exchanged with a separately provided setter (not shown) by optical communication through an optical transmission / reception circuit 32. Further, a setting mode selection switch 33 is provided to select an operation mode for registering the transmitter code in the wireless relay terminal 94. When wireless signal data is created in the signal processing unit 30 by operating the switch SW, the data is modulated by the transmission circuit 34 and transmitted as a wireless signal through the antenna 35. Here, the power supply circuit 3
A battery 6 is used.

When the setting of the transmitter code is not selected by the setting mode selection switch 33, when one of the switches SW is operated, the address data stored in the storage unit 31 and the monitoring data corresponding to the operation of the switch SW are displayed. , A wireless signal including the transmitter code stored in the storage unit 31 is transmitted. When the setting of the transmitter code is selected by the setting mode selection switch 33, when any of the operation switches SW is operated, a wireless signal including the transmitter code without address data or monitoring data is transmitted. Here, the electric field strength of the wireless signal transmitted at the time of setting the transmission code is set to about one-tenth that of the wireless signal at the time of normal transmission, and when setting the transmitter code, it is attempted to register the transmitter code. The wireless relay terminal 94 is connected to a wireless receiver Ya and used. This allows the other wireless relay terminal 94
This prevents erroneous registration of the transmitter code at the same time.

The wireless transmitter Xa has a rectangular parallelepiped casing 41a as shown in FIG. On the front surface, which is one surface in the thickness direction of the casing 41a, an operation section 42 of a tact switch, which is a push button switch having a small stroke, is arranged. That is, the switch SW is operated by pressing each operation unit 42. A setting mode selection switch 33 composed of a slide switch is exposed on the front surface of the casing 41a.
The light transmitting windows 43 corresponding to the light emitting and receiving sections are formed. A name entry section 44 for describing a load corresponding to each switch SW is provided beside each operation section 42. A holder cover 45 that is detachable from the casing 41a for opening and closing a battery holder that stores a battery serving as the power supply 36 is attached to a lower portion of the front surface of the casing 41a. Further, the permanent magnet plate 4 is provided on the rear surface of the casing 41a.
6 is fixed so that it can be attached to a steel desk or the like. The casing 41a is formed in such a size that it can be held and operated by hand as needed.

As described above, the wireless transmitter Xa can be mounted on a desk or the like and operated, or can be operated by hand, so that the wireless transmitter Xa can be operated without being moved to the installation location of the wall switch. It can be turned on and off. In addition, since wireless signals are transmitted using radio waves as a medium, partitions and people do not interfere with the transmission of wireless signals, and since there is almost no directivity, wireless signals are transmitted without aiming at the wireless receiver Ya. can do.

As the wireless transmitter Xa, there is a wireless transmitter Xa mounted on a wall as shown in FIG. The casing 41b includes a cover plate 48 coupled to the front side of the base plate 47. The base plate 47 has a flat rear surface and is arranged so as to be in close contact with the wall. The base plate 47 is fixed to the wall by screwing wood screws or the like to the wall through mounting holes 49 provided in the upper and lower portions of the base plate 47. be able to. The cover plate 48 has connecting hooks 48a projecting from the four corners on the rear surface thereof. The connecting hooks 48a are engaged with the connecting holes 47a provided in the base plate 47 so that the cover plate 48 can be connected to the base plate 47. is there. The setting mode selection switch 33 is connected to the base plate 4
7, the setting mode selection switch 33 cannot be operated when the cover plate 48 is mounted. A cover sheet 48 is provided with a membrane sheet 37 which is a thin synthetic resin sheet at a position corresponding to the operation section 42 of the switch SW.
Can be pressed. Also, the optical transmitting and receiving circuit 3
A light-transmitting window 38 is also formed in the cover plate 48 at a position corresponding to the light-transmitting window 43 provided on the base plate 47 corresponding to the second light emitting and receiving unit. Here, the casing 41b is formed so as to be thin so that the protrusion dimension from the wall surface is substantially the same as that of the wall switch, and a thin battery such as a button battery is used as the power source 36, and covers the battery holder. The holder cover 45 is arranged on the front surface of the base plate 47.

When the wireless oscillator Xa that can be mounted on the wall is used as described above, the wiring that falls from the ceiling is not required as compared with the case where a wired wall switch is used, and wiring can be easily performed. In addition, there is no risk of loss because it is fixed to the wall. ( Basic configuration 2 ) In the basic configuration 1 , the wireless signal is transmitted to the wireless receiver Y.
a, and received data is transmitted to the transmission control device 91 via the wireless relay terminal 94. As shown in FIG. 8, a wireless reception terminal 95 having a configuration connectable to the signal line Ls is used. It is also possible. That is,
The wireless receiving terminal 95 has a configuration in which the wireless receiver Ya and the wireless relay terminal 94 in the basic configuration 1 are integrally provided. More specifically, as shown in FIG. 9, a wireless signal received by an antenna 51 is demodulated by a receiving circuit 52, so that a signal processing unit 53 comprising a microcomputer can exchange data with the transmission control device 91. The same processing as that performed by the operation terminal 92 is performed. That is, the interrupt signal is transmitted to the signal line Ls connected to the terminal 58 via the transmission / reception circuit 54,
The monitoring data is returned in response to the access from the transmission control device 91. Here, in the wireless receiving terminal 95,
Address data and monitoring data are stored in the wireless transmitter X
Use the one transmitted from a. Since the transmitter code is transmitted from the wireless transmitter Xa in the same manner as in the basic configuration 1 , the transmitter code received by the wireless signal is compared with the transmitter code stored in the storage unit 55 composed of the EEPROM, The above processing is performed at the time of coincidence. The power supply of the internal circuit of the wireless reception terminal 95 is obtained by full-wave rectifying and stabilizing the transmission signal in the power supply circuit 56 in the same manner as the operation terminal 92 and the control terminal 93.

By the way, in the wireless receiving terminal 95, a registration mode selection switch 57 is provided so that a registration mode can be selected when setting a transmitter code. That is, when the operation mode for setting the transmitter code is selected by operating the setting mode selection switch 33 in the wireless transmitter Xa, the transmitter code is also set in the wireless reception terminal 95 by the wireless registration mode selection switch 57. Is selected so that the transmitter code is not registered in another wireless receiving terminal 95. That is, only when both the wireless transmitter Xa and the wireless receiving terminal 95 are in the operation mode in which the setting of the transmitter code is registered, the transmitter code is registered in the wireless receiving terminal 95. It is.

According to the above configuration, the transmitter code can be set in the wireless receiving terminal 95 without reducing the electric field intensity for outputting radio waves as in the basic configuration 1 .
Further, since there is no need to wire the wireless signal line Lw separately from the signal line Ls, workability is improved. However, since power is supplied to the wireless reception terminal 95 from the transmission control device 91, the maximum allowable number of wireless reception terminals 95 is limited by the current capacity of the transmission control device 91.

In the above configuration , the wireless receiving terminal 95
Is provided with a registration mode selection switch 57, and the registration mode selection switch 57 is operated at the time of registering the transmission code. Therefore, it is necessary to expose the wireless receiving terminal 95 indoors. Therefore, a type that is exposed on the ceiling surface and a type that is exposed on the wall surface are prepared.

The type exposed on the ceiling surface has the basic structure
1 has a container 20a having substantially the same shape as that shown in FIG. However, when the makeup cover 23 is removed, the operation unit of the registration mode selection switch 57 is exposed as shown in FIG. Basically , other shapes for the container 20a
It is the same as that shown in FIG. 3 of the configuration 1 , and the members denoted by the same reference numerals have the same functions.

As shown in FIG. 11, a type exposed to a wall has a mounting frame 61 integrally fixed to a ready-made embedding box such as a switch box or an outlet box by using a box screw. The body 20c is provided.
The mounting frame 61 is formed with a pair of mounting holes 63 spaced apart by a size corresponding to a mounting pitch to the embedding box in order to insert box screws. Also, as shown in FIG. 11B, a registration mode selection switch 5 is provided on the front surface of the body 20c.
The operation unit 7 is exposed, and a terminal 58 with a screw connected to the signal line Ls is exposed on the rear surface as shown in FIG.
The antenna 61 is built in the wireless receiving terminal 95. Also, the body 2 of the wireless reception terminal 95
After fixing Oc to the wall surface, a decorative plate 65 as shown in FIG.
The decorative plate 65 has a connecting hook protruding from the rear surface side, and is connected to the mounting frame 61 by engaging with a notch 66 formed in the mounting frame 61 in an uneven manner. In addition, decorative plate 6
Even when 5 is attached, the operation unit of the registration mode selection switch 57 is exposed on the front side. Other configuration and operation are the basic structure
It is the same as the configuration 1 . Based on the basic configuration described above,
An embodiment of the present invention will be described.

( Embodiment 1 ) This embodiment uses a wireless relay terminal 94 in the same manner as in the basic configuration 1, and as shown in FIG. 12, wireless reception for receiving a wireless signal using a radio wave as a medium. And a wireless receiver Yb for receiving a wireless signal using light (infrared light) as a medium is connected to the same wireless signal line Lw. Also, as a matter of course, the wireless transmitters Xa and Xb are also provided with one for transmitting a wireless signal of radio waves and one for transmitting a wireless signal of light.

The format and protocol of the signal transmitted to and from the wireless relay terminal 94 are set the same so that the wireless signal lines Lw are shared by both wireless receivers Ya and Yb. The signals transmitted from the wireless receivers Ya and Yb to the wireless relay terminal 94 include identification data so that the two can be identified by the device 94. In addition, since wireless signals using radio waves as a medium include a transmitter code,
A transmitter code is not required for a wireless signal using light as a medium, but a time slot corresponding to the transmitter code is provided.

When the wireless relay terminal 94 receives a signal transmitted on the wireless signal line Lw, it first determines whether the signal is a radio signal or a radio signal based on the identification data. A transmission process with the transmission control device 91 is performed using the address data and the monitoring data. If the signal is a radio wave, the transmitter code is collated. A transmission process with the transmission control device 91 is performed using the monitoring data.

Other configurations and operations are the same as those of the basic configuration 1. In this embodiment , radio waves and light (infrared rays) can be appropriately selected and used as wireless signals according to use conditions. (Embodiment 2) This embodiment, whereas uses a wireless relay terminal 94 similarly to Embodiment 1, was passed through a wireless receiver Ya when setting the transmitter code in the first embodiment, the present embodiment The difference is that the wireless relay terminal 94 directly receives the wireless signal from the wireless transmitter Xa and registers the transmitter code.

That is, as shown in FIG. 13, a signal processing unit 70 comprising a microcomputer is provided, and the monitoring data from the wireless signal Lw is transmitted to the transmission control device 91 using the address data transmitted from the wireless signal line Lw. . The signal processing unit 70 includes a transmission / reception circuit 71 that receives a signal in the voltage mode and returns a signal in the current mode between the signal processing unit 70 and the signal line Ls. The receiving circuit 7 is provided between the signal processing unit 70 and the terminal 81 connected to the wireless signal line Lw.
2, the receiving circuit 72 supplies power to the wireless receivers Ya and Yb via the wireless signal line Lw, and also has a function of detecting a short circuit of the wireless signal line Lw and cutting off the power supply. . When a short circuit occurs, the short-circuit indicator lamp 73 lights up to notify the abnormality. The wireless relay terminal 94 is also provided with an internal circuit from a commercial power supply and a power supply circuit 74 for supplying power to the wireless receivers Ya and Yb. In addition, EEPRO for storing the transmitter code
A storage unit 75 made of M is provided.

By the way, the transmitter code is directly transmitted from the wireless transmitter Xa to the wireless relay terminal 94 using the radio signal by radio waves without passing through the wireless signal line Lw. Therefore, the wireless relay terminal 94 is provided with an antenna 76 for receiving a wireless signal and a wireless signal receiving circuit 77, and also provided with a registration mode selection switch 78 for selecting an operation mode for registering the transmitter code. . The sensitivity of the antenna 76 and the wireless signal receiving circuit 77 is set lower than that of the wireless receiver Ya.

When the transmitter code is set, the registration mode is selected by the registration mode selection switch 78. In this state, the signal processing unit 70 stores the transmitter code received by the wireless signal receiving circuit 77. This is written in the section 75. Further, since switched to the operation mode to set the transmitter code is also in wireless transmitter Xa when writing a transmitter code, the basic configuration 1
