Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address number adding system and method in a power line signal carrier system applied to lighting control.

[0002]

2. Description of the Related Art Generally, a basic equipment configuration of a power line signal carrier system applied to lighting control (lighting control applied power line signal carrier system) installed in a ship, a building or the like is shown in FIG. Has become. In FIG. 3, the lighting control application power line signal carrier system includes a blocking filter 31 for limiting the reach of the control signal on the power line 30 to an appropriate section (control limited section, block), and a plurality of lighting devices. 32, a plurality of switch devices 33, and a control unit 34 are provided for each section.

The power line signal carrier system uses an electrical device to which an address number is individually assigned and its switch device, so that an arbitrary switch device turns on / off (turns on / off) the electrical device (associated with the address number). This is a system that transfers ON / OFF signals using a power line. As is well known, this power line signal carrier system is composed of a communication technique for putting a signal waveform on the power waveform on the power line and a spread spectrum technique for decomposing / combining this signal waveform into an arbitrary frequency.

In the lighting control-applied power line signal carrier system as shown in FIG. 3, it is necessary to add address numbers to each lighting device 32 and each switch device 33. Conventionally, the addition of this address number has been performed as shown in the flowchart of FIG. That is, all the lighting devices 32
On the other hand, an address number for each device is added before the site installation (step S21), and the address number of the lighting device 32 to be turned on is further extracted (step S2).
2), to each switch device 33, the switch device 3
The address number to be turned on / off in 3 is set (step S23). Then, all the lighting devices 32 and the switch devices 33 to which the address numbers have been added (set) are installed in predetermined places as shown in FIG. 3 (step S24).

[0005]

The greatest advantage of the above-mentioned power line signal carrier system to which lighting control is applied lies in the reduction of the quantity and the laying process by reducing the wire length of the power line, the signal line and the like. This effect becomes greater as the number of lighting devices and switches (switch devices) increases.

However, in the conventional system, when there are a large number of lighting devices and switches of the same type, it is necessary to select a lighting device and a switch with a specific address number from among them and to install them in a designated place without fail. It takes a lot of man-hours, and there is a problem that conflicts with the advantage of this system described above.

As a method for solving such a problem,
A method of adding an address number immediately before installation can be considered. However, this method eliminates the trouble of finding a specific address number, but makes it difficult to manage the address numbers, which causes problems such as duplicate address numbers and missing numbers.As a result, it takes time to adjust after installation. There is a problem that it takes.

The present invention has been made in view of the above points, and an object thereof is to perform adjustment after installation while maintaining the advantage of the electric wire length reduction originally possessed by the power line signal carrier system applied to lighting control. An object of the present invention is to provide an address number adding system and method that can easily perform the above.

[0009]

In order to solve the above-mentioned problems, the address number adding system in the power line signal carrier system for lighting control application of the present invention is provided with a switch device and a lighting device to provide a power source for lighting control application. Automatic address number extraction to automatically extract the address number of each lighting device in the same section (block) limited by the blocking filter during on-site adjustment (building, repair, design change) to construct the line signal carrier system Similarly, when the address number is set to the switch device in the same section at the time of on-site adjustment, by sequentially switching and designating the address numbers extracted by the address number automatic extraction means, each lighting device in the section is specified. Sequential lighting control means for sequentially lighting each is provided in the control unit, and each of the switch devices is provided. An address number setting instruction operating means for instructing and setting an address number of the lighting device turned on by the sequential lighting control means, and a sequence of each lighting device by switching designation of the address numbers from the sequential lighting control means. When the address number setting is instructed by the address number setting instruction operating means while it is lit,
At that time, an address number setting means for setting the address numbers of the lighting devices that are turned on by designating the address numbers of the sequential lighting control means is provided.

In the address number adding system having the above structure, each lighting device is installed regardless of the address number of the lighting device (address number assigned to the lighting device), and each switch device is installed before setting the address number. It is supposed to be done.

In the address number addition system having the above structure, the wiring / wiring of each lighting device and each switch device
In the on-site adjustment after installation, a process of associating each lighting device with a switch device assigned for operating the lighting device by the address number of the lighting device is performed as follows.

First, the address number automatic extraction means in the control unit extracts the address number of each lighting device in the same section. This address number extraction can be realized by sequentially transmitting the address numbers from, for example, the minimum value to the maximum value of the address number from the automatic address number extraction means, and receiving the response from the lighting device of the address number.

Next, in order to set an address number to the switch device in the same section, the extracted address numbers are sequentially switched and designated by the sequential lighting control means in the control unit, whereby Each lighting device is sequentially turned on for a fixed time.

Then, during the sequential lighting of each lighting device by the switching designation of the address number of the sequential lighting control means,
Whenever the address number setting instruction operating means (for example, switch) of the switch device in the same section is operated, the address number setting means of the switch device each time, the address numbers designated by the lighting control means at that time. That is, the address numbers of the lighting devices that are turned on by designating the address numbers of the sequential lighting control means are set for the operation of the lighting devices.

The above setting process is sequentially performed for all the switch devices for which the address number of the lighting device is desired to be set. As described above, in the address number addition system of the present invention, when performing the on-site adjustment after the installation of the lighting device and the switch device, the O from the switch device to which the address number is to be set
While the N / OFF operation target illumination device is on, the operator simply operates the address number setting instruction operating means of the switch device to instruct the address number setting without being aware of the address number. The address number of the lighting device that is lit can be automatically set in the switch device, and the address number can be set and the final adjustment can be made with a minimum number of steps. That is, according to the present invention, it is possible to easily perform the adjustment after installation while maintaining the advantage of the electric wire length reduction originally possessed by the power line signal carrier system.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a lighting applied power line signal carrier system realized by using the address number addition system of the present invention, FIG.
3 is a flowchart for explaining an address number addition (setting) process in the same embodiment.

The basic equipment configuration of the illumination applied power line signal carrier system in this embodiment is the same as the conventional system shown in FIG. 3 (however, the internal configuration of each equipment is different from the conventional system), and FIG. As shown in. In FIG. 1, the lighting-applied power line signal carrier system determines an appropriate range of control signals on the power line 10 by a suitable block (section)
Blocking filter 11 composed of a low frequency transformer or the like for limiting
The illumination device 12, the one or more (here, a plurality of) switch devices 13, and the control unit 14 are provided for each section. In FIG. 1, the lighting device 1
2. Regarding the internal configurations of the switch device 13 and the control unit 14, only one lighting device 12, the switch device 13 and the control unit 14 are shown, but the other lighting devices 12, the switch device 13 and the control unit 14 are shown. Is also the same.

In the address number adding process of this embodiment, the address numbers provided to the lighting devices 12 before the lighting devices 12 are installed as shown in FIG. 1, for example, when the lighting devices 12 are manufactured. An address number is arbitrarily set in the setting device 121 so that the address numbers do not overlap among the lighting devices 12 (step S1).

Then, the worker operates each lighting device 1 whose address number is set in the address number setting device 121 in this way.
2, regardless of the corresponding address numbers, together with the switch devices 13 and the control unit 14, are installed and wired in a ship or building as shown in FIG. 1 (step S
2). For example, if the total number of lighting devices 12 installed on a certain ship is 500, each lighting device 12 is set by assigning a three-digit serial number as an address number, and
The individual lighting devices 12 are installed ignoring the corresponding address numbers. In this case, it is unknown which address number of the lighting device 12 is installed in which position of which block.

Now, each lighting device 12 and the switch device 1
When 3 and the like are installed as shown in FIG. 11, the address number automatic extractor 141 provided in the control unit 14 of each block is activated. Then, the address number automatic extractor 141 automatically extracts the address numbers of all the lighting devices 12 installed in the same block, and registers them in the existing address number storage 142 provided in the control unit 14. (Steps S3, S4)
Is performed as described below.

First, the address number automatic extractor 141 transmits the signal A indicating the automatic address number extraction, and subsequently the signal of the address number, that is, the operation of transmitting the signal of the address number to which the signal A is added. Is repeatedly executed from address numbers 000 to 999.

The signal (A + address number) of the address number added with the signal A (indicating automatic address number extraction) transmitted from the address number automatic extractor 141 in the control unit 14 is the power supply line in the same block. 10
(Or a signal line connected to the power line 10),
It is sent to each lighting device 12.

Each lighting device 12 is provided with a discriminator 122 and a response circuit 123. The discriminator 122 discriminates from the signal sent from the address number automatic extractor 141 (in the control unit 14) whether the address number is automatically extracted or the illumination is turned on / off.

If a signal having an address number to which the signal A indicating the automatic address number extraction is added is sent from the automatic address number extractor 141, the discriminator 122 in each lighting device 12 automatically extracts the address number. Is determined and the signal of the subsequent address number is passed to the response circuit 123. Then, the response circuit 123 determines whether or not this address number matches the address number preset in the address number setting unit 121, that is, whether or not it is its own address number, and it is the own address number. Only in the case, the response is returned to the control unit 14 (via the discriminator 122).

The address number automatic extractor 141 in the control unit 14 sets the same address number only when there is a response to the address number (from the response circuit 123 in the illuminating device 12) which is transmitted by itself. Existing address number storage device 1 provided in 14
42 to register.

The above-mentioned operation is carried out by the address numbers 000 to 9
By repeating the process up to 99, the address numbers (set in the address number setting unit 121) of all the lighting devices 12 installed in the same block among these address numbers become the existing address number storage unit 14
2 (for example, 012, 018, 035, 109, 11
It will be registered in ascending order (0, ...).

In this way, for each block, the address numbers of all the lighting devices 12 installed in that block are automatically extracted and registered in the existing address number storage unit 142 in the control unit 14. .

In this state, the operator operates the control unit 14 by, for example, operating a predetermined button to arbitrarily illuminate each switch device 13 in the same block based on the registered contents of the existing address number memory 142. The start of the process for setting the address number of the device 12 is instructed (step S5).

Next, the operator wants to set the address number to the switch device (switch device to which the address number is set) 1
3 is designated (determined), and the control unit 14 is instructed to set the illumination device address number to the designated switch device (switch device to be set) 13 by, for example, operating a predetermined button (step S6). .

The control unit 14 is provided with a mode setter 143. This mode setter 143
When the operator designates the setting switch device 13 (in the designation mode of the setting switch device 13),
The address number of the lighting device 12 that can be turned on / off is automatically extracted from the existing address number storage 142 (step S7). That is, the mode setting unit 143 sequentially reads the address numbers of the lighting devices 12 that can be turned on / off, which are registered in the existing address number storage unit 142. Then, every time the address number is read from the existing address number storage unit 142, the mode setting unit 143 performs a process (step S8) for turning on the lighting device 12 to which the address number is assigned for a certain period of time (for example, several seconds). Do the following:

First, the mode setter 143 in the control unit 14 outputs a signal (lighting signal) B indicating lighting to the address number read from the existing address number storage 142.
Is added to each lighting device 12 and each switching device 13 in the same block.

When the discriminator 122 in the lighting device 12 receives the address number to which the lighting signal B is added, the discriminator 122 discriminates that the address number is for lighting, and the address number with the signal B is It is passed to the address number discriminator 124 provided in the same lighting device 12.

Then, the address number discriminator 124 in the lighting device 12 sets the address number (with the signal B) from the control unit 14 (in the mode setter 143) passed from the discriminator 122. Bowl 1
It is determined whether or not it matches the address number preset in No. 21, that is, whether or not it is its own address number, and only when it is its own address number, the lighting 125 of the lighting device 12 is turned on / off. Switch 126 for
N. As a result, the illumination 125 of the illumination device 12 to which the address number (lighting signal) sent from the control unit 14 (the mode setting device 143 therein) is assigned is turned on.

The mode setter 143 in the control unit 14 adds a signal (extinguishing signal) C indicating that the address is turned off after a certain period has elapsed from the start of transmission of the address number to which the lighting signal B is added, It transmits to each lighting device 12 and each switch device 13 in the same block.

When the discriminator 122 in the lighting device 12 receives the address number to which the extinguishing signal C is added, the discriminator 122 discriminates that the address number is for extinguishing, and the address number with the signal C is addressed. It is passed to the number discriminator 124.
The address number discriminator 124 includes the control unit 14 (the mode setter 14 in the control unit 14 delivered from the discriminator 122.
Only when the address number (with the signal C) from 3) matches the address number preset in the address number setting unit 121, the switch 126 is turned off and the illumination 1
Turn off 25.

In this way, the operation of adding the turn-on signal B to the address number extracted in step S7 and transmitting, and the operation of adding the turn-off signal C to the address number and transmitting after a certain period of time are performed in the control unit 14. Is performed by the mode setter 143 of the lighting device 1 of the address number.
2 (the illumination 125) can be turned on for a certain period of time.

Now, from the control unit 14 (the mode setter 143 therein) (the lighting signal B is added)
According to the designation of the address number, the lighting 12 of the lighting device 12
When 5 is turned on, if the operator wants to register (set) the address number of the illuminating device 12 in the set switch device 13 designated by the operator, the operator pushes the confirmation switch 131 provided in the switch device 13. Push. In the present embodiment, the confirmation switch 131 is built in the housing of the switch device 13 unlike the lighting switch 134 and the extinguishing switch 135, which will be described later, and cannot be easily operated by a third party. Will operate the confirmation switch 131 by removing the cover or the like of the switch device 13.

The switch device 13 includes a confirmation switch 13
1, the writer 132 and the address number memory 1
33 are provided. In the writer 132 in the switch device 13, as described above, the confirmation switch 131 is pressed in a state where the address number is sent from the control unit 14 (the mode setter 143 therein) and the lighting device 12 is lit. (Step S9), the address number is regarded as the address number to be turned on (and turned off) by the switch device 13, and the switch device 1
It is registered (set) in the address number memory 133 of No. 3 (step S10). At this time, if there is an already registered address number in the address number storage unit 133, a new address number is additionally registered at, for example, the subsequent position of the address number. That is, in the present embodiment, the address numbers of the plurality of lighting devices 12 may be registered for one switch device 13.

Now, when the mode setter 143 in the control unit 14 turns on the lighting device 12 of the address number extracted (read out) from the existing address number memory 142 for a certain period of time, the set switch device is turned on during the lighting. Even when the confirmation switch 131 of 13 is pressed and the address number is registered (set) in the switch device 13 (the address number storage unit 133 therein), the confirmation switch 1
Even if 31 is not pressed and the address number is not registered in the switch device 13 to be set, whether or not the processing for all the address numbers extracted (read out) from the existing address number storage 142 is completed, That is, for all the address numbers registered in the existing address number storage unit 142, it is checked whether or not the lighting of the corresponding lighting device 12 (for a certain period of time) and the transmission of the address number to the switch device 13 have been completed (step S11). ).

If an unprocessed address number remains, the mode setter 1 in the control unit 14
The step 43 returns to step S8 and performs the above-mentioned processing for the subsequent address numbers in the existing address number storage 142. Then, the above process is repeated for all the address numbers registered in the existing address number storage 142, and when there is no target lighting device 12 (lighted for a certain period of time) (step S11), the control unit 1
The mode setter 143 in 4 finishes the address number setting to the designated switch device 13 to be set.

Then, the operator determines whether or not the switch device 13 for which the address number of the illuminating device 12 is desired to be set (registered) remains (step S12). One switch device 13 to be registered) is selected and newly designated as the switch device 13 to be set (step S6). Thereafter, similarly to the above, the lighting device 12 is attached to the switch device 13 designated by the operator.
A process for setting the address number of is performed.

In this way, when the address numbers of the illumination device 12 are set (registered) for all the switch devices 13 desired by the worker, all address number setting processing is completed.

After that, the use mode is set by the mode setter 143 in the control unit 14.
In this usage mode, when, for example, the lighting switch 134 of the lighting switch 134 and the extinguishing switch 135 provided in the desired switch device 13 is pressed, the reader 136 connected to the lighting switch 134 stores the address number. The address number registered in the storage unit 133 is read from the device 133, the lighting signal B is added, and the signal is sent to the control unit 14. Similarly, when the turn-off switch 135 is pressed, the turn-off signal C is added to the address number and sent to the control unit 14.

The mode setter 143 in the control unit 14 is in the bypass state in the use mode. Therefore, the address number to which the turn-on signal B or the turn-off signal C added from the reader 136 in the switch device 13 passes through the mode setter 143 in the control unit 14 as it is, and the blocking filter 1
It is sent to each lighting device 12 in the same block as the switch device 13 restricted by 1.

When the discriminator 122 in each illuminating device 12 receives the address number to which the lighting signal B or the extinguishing signal C is added as in this example, the address number is used as a signal for lighting or extinguishing the illumination. It is determined that there is a signal B
Alternatively, the address number with C is passed to the address number discriminator 124 provided in the same lighting device 12.

Then, the address number discriminator 124 in the lighting device 12 receives the signal B or C passed from the discriminator 122 (transmitted from the reader 136 in the switch device 13 via the control unit 14). The attached address number is compared with the address number preset in the address number setter 121, that is, its own address number, and the switch 126 is turned on according to the signal B or C only when both addresses match. Turn on or off.
As a result, the address number passed from the discriminator 122,
That is, the illumination 12 of the illumination device 12 having the address number that matches the address number from the switch device 13 in the same block.
Only 5 turns on or off.

Although the above embodiments have been described with respect to the address number addition system for the lighting control-applied power supply line signal carrier system, the present invention is not limited to the lighting device, and other electric devices can be connected to the power supply line from the switch device. The present invention can be applied to a general power line signal carrier system operated via the electronic equipment as long as the ON / OFF state (corresponding to turning on / off of the lighting device) of the electric device can be discriminated by the operator.

[0048]

As described in detail above, according to the address number adding system and method for the lighting control application power line signal carrier system of the present invention, the operator can perform on-site adjustment after installing the lighting device and the switch device. At the time of (construction, repair, design change)
While the lighting device to be operated by N / OFF is turned on, the address number setting can be performed by simply instructing the switch device to set the address number without paying attention to the address number. Since the address number can be automatically set in the switch device, the installation man-hours of the lighting device and the switch device that occur during on-site adjustment can be minimized while maintaining the effect of reducing the installation man-hours inherent in the power line signal carrier system. Can be limited.

Further, according to the present invention, due to the above effects,
