There is a problem that it cannot be used for the purpose of using the wireless transmitter Y in correspondence with a large number of control terminals 43, for example, for turning on a nearby luminaire when patrol in a building or the like. . In order to achieve such an object, it is conceivable to set a channel in the wireless receiver X without including the address data AD in the wireless signal. However, in this case, since the wireless signal from one wireless transmitter Y can be received by any wireless receiver X, the wireless signals are simultaneously received by a plurality of wireless receivers X to cause interference. There is.

Thus, the wireless receiver can be directly connected to the transmission line without going through the wireless relay terminal.

(Embodiment 1) In this embodiment, the wireless transmitter Y is provided with a maximum of four push-button switches similarly to the monitoring terminal 42 shown in FIG. A wireless signal of a predetermined format including information is transmitted. As shown in FIG. 3, the wireless receiver X includes a light receiving unit 1 for receiving infrared light having a photodiode or the like, and an output of the light receiving unit 1 is a wireless signal processing unit 2.
Identified by The wireless signal processing unit 2 determines whether the wireless signal satisfies a predetermined format, identifies a push button switch corresponding to a wireless signal of a predetermined format, and includes information corresponding to a load number. Output the output signal. An output signal of the wireless signal processing unit 2 is input to a terminal processing unit 3 mainly including a microcomputer. Upon receiving the output of the wireless signal processing unit 2, the terminal processing unit 3 transmits an interrupt signal Vi to the main control device 41 through the transmission line terminal T connected to the transmission line Ls. Main controller 41 that has received interrupt signal Vi transmits transmission signal Vs to wireless receiver X. In the wireless receiver X, when the channel set by the channel setting unit 5a matches the channel included in the address data AD of the transmission signal Vs, the wireless receiver X corresponds to the load number included in the output signal of the wireless signal processing unit 2. The monitoring data including the data to be monitored is created, and the monitoring data is returned to the main controller 41 in synchronization with the signal return period WT. The channel setting section 5a is configured using a digital switch or the like. The monitoring data is transmitted as a current mode binary signal depending on whether the lines of the transmission line Ls are short-circuited or opened via a low resistance. A power supply circuit 4 is connected to the transmission line terminal T, and the power supply circuit 4 rectifies and stabilizes a multi-polar transmission signal Vs transmitted through the transmission line Ls, and performs wireless signal processing 2 and terminal processing 3 Power is supplied to

By the way, the above-mentioned circuit section is housed in a case 10 as shown in FIGS. Case 1
0, a circuit board 6 on which the wireless signal processing section 2 is mounted together with the light receiving section 3 in addition to the circuit board 5 on which the terminal processing section 3 and the like are mounted. 6 are delivered in a stacked form. Case 10
Is formed by fitting a disk-shaped cover 12 into an opening on the lower surface of the body 11 and connecting the assembly with an assembling screw 14 composed of a tapping screw. The peripheral portion of the cover 12 projects from the peripheral surface of the body 11 to form a flange 13. A terminal 16 (corresponding to a terminal T in FIG. 3) having terminal screws exposed on the upper surface of the case 10 is connected to the circuit board 5 via a lead wire 15. At the center of the lower surface of the body 11, a filter 17 for selectively transmitting infrared light is provided so as to cover the front of the light receiving surface of the light receiving unit 1 mounted on the circuit board 6. As described above, since the filter 17 is disposed without disposing a wide-angle light receiving lens on the front surface of the light receiving unit 1, the light receiving area of the light receiving unit 1 can be set narrow. Even when X is located relatively close, the probability that the wireless signal is received by the target wireless receiver X can be reduced, and only the target load can be turned on and off. Become.

A pair of long holes 18 are formed in the flange 13, and a fixing screw 21 is inserted through each of the long holes 18. A mounting bracket 20 is inserted through an intermediate portion of the fixing screw 21, and a nut 22, which is prevented from rotating with respect to the mounting bracket 20, is screwed into an end of the fixing screw 21. The base end of the mounting bracket 20 is pivotally mounted on the upper part of the body 11, and the distal end can change the distance from the flange 13. Further, a return spring 23 is connected to the mounting bracket 20, and the distal end portion is urged in a direction away from the flange 13.

Therefore, when the case 10 is mounted in a mounting hole formed in a mounting panel such as a ceiling panel, the fixing screw 21 is loosened, and the distal end of the mounting bracket 20 is separated from the flange 13 by the spring force of the return spring 23. (That is, the distance between the distal ends of the mounting brackets 20 is reduced). In this state, the body 11 and the fixing screw 21 are inserted into the mounting holes, and the flange 13 is brought into contact with the surface of the mounting panel. Next, when the fixing screw 21 is tightened, the tip of the mounting bracket 20 approaches the flange 13, and the mounting panel can be sandwiched between the flange 13 and the mounting bracket 20. After fixing the case 10 to the mounting panel as described above, the decorative plate 24 is attached so as to cover the lower surface of the flange 13. By forming the case 10 into the shape described above, attachment to a construction panel such as a ceiling panel becomes easy. Further, the flange 13 has a pair of fixing holes for inserting a box screw screwed into the embedding box so as to cope with a case where an embedding box such as a switch box for wiring equipment is embedded in the ceiling. 19 are formed.

When controlling the load L such as a lighting fixture, as shown in FIG. 4, the wireless receiver X in which the correspondence with the control terminal 43 is set by the channel setting unit 5a is connected to the corresponding load L. To be placed near the In this manner, the wireless transmitter Y can turn on / off the desired load L only by transmitting a wireless signal to the wireless receiver X near the desired load L. That is, it is not necessary to specify the load L to be controlled by the wireless transmitter Y, but only to specify ON and OFF, so that the wireless transmitter Y can be made to correspond to an arbitrary wireless receiver X. That is, a wireless relay terminal is not required, and when patrol at night in a building or the like, if the wireless transmitter Y is carried around, the lighting equipment can be turned on and off without operating the wall switch. It is. Also, since address data necessary for transmission and reception of a transmission signal transmitted through the transmission line Ls is set inside the wireless receiver X, no address data is required for the wireless signal, and the signal format of the wireless signal is simple. There is also the advantage of becoming.

(Embodiment 2) In the first embodiment, the light receiving section 1 and the filter 17 are fixed to the case 10, but in the present embodiment, as shown in FIGS. The filter 17 is held by a movable body 30 whose direction can be adjusted with respect to the case 10. That is, the movable body 30 is formed in a substantially spherical shape, and the circuit board 6 on which the light receiving unit 1 is mounted is mounted therein, and the lower half is a hemispherical filter 17. At the upper end of the movable body 30, a position regulating protrusion 31 is projected, and a holding plate 32 having an opening through which the peripheral part of the position regulating protrusion 31 is inserted and connected to the cover 12, and a lower surface of the cover 12. Movable body 30 between opening
Are held, the movable body 30 is held in the cover 12. Therefore, the direction of the movable body 30 can be adjusted with respect to the cover 12 within a range in which the position regulating projection 31 can move within the opening of the holding plate 32.

As described above, by providing the light receiving section 1 and the filter 17 on the movable body 30, if the direction of the movable body 30 is changed, the direction of the center line of the wireless signal reception range can be adjusted. Therefore, it is possible to set so that the wireless signal reception ranges of the wireless receivers X do not overlap with each other, or to set the reception range in a target direction.

(Embodiment 3) In the above embodiment, only the transmission line terminal T connected to the transmission line Ls was provided as the terminal T. However, in this embodiment, as shown in FIG. An embodiment in which a wireless relay terminal Tw connected to the line Lw is added is shown. That is, as shown in FIG. 8, the output of the light receiving unit 1 is configured to be input to the wireless signal processing unit 2 and also to the wireless signal relay processing unit 6. In the wireless signal relay processing unit 6, the wireless signal received by the light receiving unit 1 is
When the address data corresponding to the address data of s (see FIG. 12) is included, an output signal including the address data is generated and transmitted from the wireless relay terminal Tw. Therefore, as shown in FIG. 10, by connecting the wireless relay terminal Tw to the wireless transmission line Lw, an output signal including address data can be transmitted to the wireless relay terminal 44. In this case, the wireless relay terminal 44 receiving the address data sets the channel of the address data as the channel of the wireless relay terminal 44, and sends the address to the control terminal 43 which has a correspondence set by this channel. The load number of the data is transmitted, and the desired load is controlled.

In short, in the configuration of this embodiment, since the transmission line terminal T and the wireless relay terminal Tw are provided, it is possible to connect to both the transmission line Ls and the wireless transmission line Lw. Therefore, two types of usage, a system surrounded by a broken line and a system surrounded by an alternate long and short dash line in FIG. 8, can be shared by one type of product. Here, in the configuration shown in FIG. 8, in addition to the channel setting unit 5a, the load number setting unit 5b and the control mode selection switch 5
c. That is, in the first embodiment, the load number is designated by the wireless transmitter Y. However, in the present embodiment, the channel and the load number are wirelessly determined by providing the load number setting unit 5b in the wireless receiver X. It is specified by the receiver X. Therefore, the correspondence with the control terminal 43 is specified by the channel setting unit 5a, and which of the four loads connected to the control terminal 43 is controlled is specified by the load number. In such a configuration, the wireless signal does not include information about the load number,
Only the information on the presence or absence of a wireless signal needs to be transmitted from the wireless signal processing unit 2 to the terminal processing unit 3, and the format of the wireless signal is simplified. The signal from the wireless signal processing unit 2 to the terminal processing unit 3 is also a simple signal such as one pulse. The control mode selection switch 5c controls an individual control mode in which the load is controlled in one-to-one correspondence with the control terminal 43, and a group control in which a plurality of loads are collectively controlled in one-to-many correspondence with the plurality of control terminals 43. The mode is alternately selected. When the individual control mode is selected, the operation is performed in the same manner as in the first embodiment. When the group control mode is selected, a group channel as a group name of the control terminals 43 belonging to the same group is set in the channel setting unit 5.
a, and the loads having the same load number in the control terminals 43 in the group are collectively designated by the load number setting unit 5b, so that the control terminals 43 belonging to the same group Among them, loads having the same load number can be controlled collectively. With this configuration, the wireless receiver X can be used for both individual control and group control, and the usage can be expanded. Other configurations and operations are the same as those in the first embodiment.

As described above, the present invention relates to a light receiving section for receiving a wireless signal by light, a wireless signal processing section for generating an output signal when a wireless signal is received by the light receiving section, and a wireless signal processing section for monitoring data. A terminal processing unit that generates the monitoring data in response to an output signal of the terminal. When the monitoring data is generated, the terminal processing unit generates an interrupt signal to the main controller, and a transmission signal including address data is transmitted from the main controller. Since the created monitoring data is transmitted back to the main controller when transmitted via the line, the wireless receiver can transmit and receive a transmission signal to and from the main controller. There is an effect that it is possible to directly connect to the transmission line without going through the wireless relay terminal. For example, if the load is a lighting fixture, if a wireless receiver is arranged near the corresponding lighting fixture, the load can be specified only by sending a wireless signal to the wireless receiver. In addition, the address data is

By not using, the reception range of the wireless signal is set relatively narrow,
As a result, even if the wireless receivers are arranged at relatively short distances, simultaneous reception of wireless signals by a plurality of wireless receivers can be avoided, and there is an advantage that the possibility of interference is reduced.
