[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control lighting control device applied to control a plurality of remote control lighting fixtures for projecting light to an actor or a studio set in a television studio or a stage of various halls. Regarding

[0002]

2. Description of the Related Art Conventionally, as an example of a method for controlling a plurality of remote control lighting fixtures, a unique address is assigned to each of the remote control lighting fixtures, and the address data for designating the remote control lighting fixtures is sent from the remote control lighting control device. A method for transmitting the added control command has been proposed. In such a method, if each part of the remote control lighting device is normal, a predetermined response signal is returned from the remote control lighting device that has received the control command to the remote control lighting control device. However, there is something wrong with the remote control lighting equipment itself, or noise is mixed in the communication path,
In some cases, an appropriate response signal may not be returned. Therefore,
Conventionally, when an appropriate response signal is not returned from the remote control lighting device to the remote control lighting control device, re-transmission of the control command to the remote control lighting device passes a predetermined time (response waiting time). I was running repeatedly.

FIG. 4 shows such a conventional control system, in which the remote control lighting control device Ae sequentially sends control commands Sc1, Sc2, ... To three remote control lighting fixtures B1 to B3.
In the case of transmitting
There is a case where the appropriate response signal Sd2 is not returned from the remote control lighting device B2 in response to the transmission of 2. In this case, conventionally, the transmission of the control command Sc2 to the remote control lighting fixture B2 is repeatedly executed within a certain time, and if this times out, at that time, the control command Sc3 to the remote control lighting fixture B3 of the next address is reached. Was being sent. Then, conventionally, when transmitting the control command Sc2 ′ again to the malfunctioning remote control lighting device B2, the same procedure as above is repeated.

[0004]

However, in the above-mentioned conventional one, the remote control lighting device B which does not normally operate.
The control command is issued to the remote control lighting device B1 as well as other normal remote control lighting devices B1 and B3, and a certain response waiting time is spent when the command is issued to the remote control lighting device B2. Therefore, in the past,
During this response waiting time, other normal remote control lighting fixtures B1 and B3 cannot be controlled. as a result,
The control of these normal remote control lighting fixtures B1 and B3 is delayed, and eventually there is a problem that real-time control of the entire remote control lighting fixture becomes difficult.

The present invention has been proposed in view of the above points, and it is possible to avoid wasting time to issue a control command to a remote control lighting device that does not perform a normal operation, so that another normal remote control lighting device can be operated. Its purpose is to enable proper real-time control of.

[0006]

SUMMARY OF THE INVENTION A remote control lighting control device according to the present invention as set forth in claim 1 proposed to achieve the above object, is provided for each of a plurality of remote control lighting fixtures having a unique address. On the other hand, a normal response signal is returned from the communication means for transmitting the control command to which the address data of the remote control lighting equipment is added and the remote control lighting equipment of the transmission destination after transmitting the control command from this communication means. And a control means for controlling to execute transmission of a control command for executing the next control of the remote control lighting equipment.
When the number of abnormal response of the remote control lighting equipment to which the control command is transmitted reaches a preset number of times, the control means stores the address of the remote control lighting equipment having the abnormal response in the storage unit, and thereafter. It is configured to perform control so as to avoid transmission of the control command to the remote control luminaire having the address stored in the storage unit and execute transmission of the control command to the remote control luminaire having another address. Note that the abnormal response mode of the remote control lighting device includes both a case where a response signal is not returned and a case where the response signal is returned and the signal is abnormal.

According to a second aspect of the present invention, in the remote control lighting control device according to the first aspect of the present invention, in the configuration of the first aspect, the control means causes the remote control lighting fixture to which the control command is transmitted to have two abnormal response times. When it becomes, the address of the remote control luminaire having the abnormal response is stored in the storage unit.

According to a third aspect of the present invention, in the remote control lighting control device according to the first aspect of the present invention, in the configuration of the first aspect, the control means sets the number of abnormal response times of the remote control lighting equipment to which the control command is transmitted in advance. Instead of the control of storing the address of the remote control lighting device with abnormal response when the set number of times is reached, the destination becomes the destination within a certain time set in advance from the start of transmission of the control command. When a normal response signal is not returned from the remote control lighting device, it is configured to perform control to store the address of the remote control lighting device having the abnormal response in the storage unit. Configured to avoid sending control commands to remote control luminaires and perform control command transmissions to remote control luminaires at other addresses. That.

[0009]

In the remote control lighting control device according to the present invention as set forth in claim 1, the remote control lighting fixture is capable of transmitting a control command due to a malfunction of the remote control lighting fixture, a communication failure, or the like. If an appropriate response signal is not returned and there is a response abnormality, the address of the remote control lighting equipment having the response abnormality is stored in the storage unit when the number of response abnormalities reaches a preset number. Memorized in. Then, thereafter, the control command is not transmitted to the remote control lighting device in which this address is stored, but the control command is transmitted to the other remote control lighting device that performs normal operation. Therefore, it is possible to save a wasteful time of repeatedly transmitting the control command to the remote control lighting device having the abnormal response, and to perform real-time control of another remote control lighting device that normally operates.

In the remote control lighting control device according to the second aspect of the present invention, the address of the remote control lighting fixture is stored in the storage unit when the number of response abnormalities of the remote control lighting fixture reaches 2. After that, the control command is not transmitted to the remote control lighting equipment. Therefore,
Since the abnormal response of the remote control lighting equipment also occurs due to, for example, temporary mixing of noise into the signal transmission path, even if the number of abnormal response times of the remote control lighting equipment occurs once, the response abnormality is temporary. It is difficult to judge whether it is a good one or not. Therefore, if it is determined that the remote control lighting device is malfunctioning when the number of response abnormalities is 2, the certainty of the determination is increased and the determination can be made early.

In the remote control lighting control device according to the third aspect of the present invention, when the normal response from the remote control lighting equipment is not within a fixed time regardless of the number of abnormal response from the remote control lighting equipment. , The address of the remote control lighting device having the abnormal response is stored in the storage unit. Then, thereafter, the control command is not transmitted to the remote control lighting device having the abnormal response. Therefore, as in the case of claim 1 or 2, the wasteful time of repeatedly transmitting the control command to the remote control lighting equipment having the abnormal response is eliminated, and the real-time control of other remote control lighting equipment in normal operation is eliminated. It can be carried out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a hardware configuration of a remote control illumination control device A according to the present invention. The remote control lighting control device A includes a control unit 1 (corresponding to the control means of the present invention) including a CPU, a storage unit 2 including a ROM and a RAM that function as a system memory, a communication unit 3, An operation unit 4 provided with various switches for instructing remote operation of a plurality of remote control lighting devices B.
And a timer 5 and the like. Remote control lighting B
.. As an example, a spotlight is used in which the projection angle in the pan / tilt direction is variable and the focus control is free.

Of the above, the communication unit 3 executes mutual transmission of various control commands and response signals to and from a plurality of remote control lighting fixtures B, ..., One example of which is a plurality of remote control lighting fixtures. A type that is connected to B ... through a communication line and executes multiplex transmission is applied. Other than this, a wireless communication device that executes wireless communication using radio waves, infrared rays, or the like can be applied. A control command to which the unique address data attached to each remote control lighting fixture B is added is transmitted from the communication unit 3, and the remote control lighting fixture B corresponding to the address data receives the command. Then, the remote control lighting device B is configured to return a predetermined response signal to the communication section 3.

The control unit 1 operates the operation unit 4 or the storage unit 2.
The operation control and the signal processing control of each unit such as the communication unit 3 are executed according to the program stored in advance. However, when the remote control of the remote control lighting device B ... Is performed, the following control is performed. There is. That is, the control unit 1 is configured to perform control so that, after transmitting one control command, when a response signal corresponding thereto is returned from the remote control lighting device B, the next control command is transmitted. There is.

Despite the control command being transmitted, the control unit 1 does not return a response signal from the remote control lighting device B within a certain time, or even if a response signal is returned, the content of the response signal is changed. When a response abnormality occurs due to an abnormality or the like, the control command to the remote control lighting device B is retransmitted. Next, when a response abnormality occurs again with respect to the retransmission, and the number of response abnormalities reaches a preset fixed number (for example, 2 times), the control unit 1 at that point causes the remote control lighting device B in the response abnormal state. Is determined to be malfunctioning, and the address data of the remote control lighting fixture B is used as the address data of the response abnormality and R of the storage unit 2
Store and store in AM. Then, the transmission of the control command to the next remote control lighting device B is started.

The control unit 1 previously refers to the address data of the response abnormality stored in the RAM when transmitting the control command. As a result of this reference, when the address data to be added to the control command matches the address data of the abnormal response already stored in the RAM, the control unit 1 no longer controls the remote control lighting device B at that address. Do not send the command. Then, the remote control lighting device B at the next address is configured to be controlled so as to transmit a control command.

Next, the remote control lighting control device A having the above structure
An example of use and action of will be described. For convenience, each address of the remote control lighting fixtures B1 to B3 shown in FIG. 1 is “1”.
Is set to "3". In FIG. 2, first, when the control command Sa1 to which the address data 1 is added is transmitted from the remote control lighting control device A, this is received by the remote control lighting fixture B1 and the response signal Sb1 is returned. Then, after that, the control command Sa2 to which the following address data 2 is added is transmitted from the remote control lighting control device A, but in the case where the remote control lighting device B2 has failed or an abnormality has occurred in its communication path. , Response signal S
b2 is not returned. In this initial state, the address data of the remote control lighting device B2 is still RAM.
Since the number of abnormal response times has not reached a fixed number, the control command Sa2 to which the address data 2 is added is transmitted again.

Then, even when the control command Sa2 is retransmitted, an appropriate response signal S is sent from the remote control lighting device B2.
If b2 is not returned, and if the response signal is returned, but the signal content is abnormal, the total number of response abnormalities will reach a preset number (for example, 2 times). Therefore, at that time, the address "2" of the remote control lighting device B2 is stored in the RAM of the remote control lighting control device A as address data of abnormal response, and the control command Sa3 to the remote control lighting device B3 to which the next address is attached is given.
Is started to be transmitted.

When transmitting the above-mentioned control command,
The control unit 1 of the remote control lighting control device A determines whether or not the address data to be added to the control command is already registered as the response abnormal address data stored in the RAM. Therefore, after the address "2" is registered in the RAM as address data of abnormal response as described above, a control command should be transmitted to the remote control lighting device B2 as indicated by an arrow a in FIG. Even in the order, no control command is transmitted to this remote control lighting device B2. Then, the control command is transmitted to the next remote control lighting device B1, for example. As a result, the remote control lighting device B that does not operate normally
It is possible to save a certain amount of wasted time from transmitting the control command to the control command No. 2 until waiting for the response, and to appropriately control other normal remote control lighting fixtures B1 and B3 in real time.

As described above, the control unit 1 determines whether the address data added to the control command matches the address data of the response abnormality registered in the RAM in advance. This determination is made by the control command. Since it can be performed quickly in a short time, for example, about 1/1000 of the time required for transmission, this does not delay each control of the remote control lighting device B.

Steps 100 to 100 of the flowchart of FIG.
Reference numeral 111 denotes a series of operation procedures of the remote control illumination control device A described above.

For the remote control lighting device B2 which has been determined to be malfunctioning due to the occurrence of abnormal response twice, a recovery inspection or the like may be performed when the controller 1 is idle. As a result, when the remote control lighting device B2 can be restored to the normal operation state, the address data of the remote control lighting device B2 stored in the RAM at that time may be deleted.

In the above-mentioned embodiment, when the response abnormality occurs twice, it is determined that the remote control lighting device B is malfunctioning (corresponding to claim 2). The specific number of times is not limited to this. For example, when the response abnormality occurs once, it may be immediately determined that the remote control lighting device is malfunctioning. Moreover, the response abnormality is 3
It may be determined that the operation is defective when the operation occurs once or more times. Further, the number of times may be fixed, but may be arbitrarily changed by the user by operating the operation unit 4, for example.

Further, in the above embodiment, it is determined that the remote control lighting equipment is malfunctioning when the number of abnormal response times reaches a preset number of times, but the present invention uses a different determination method. Can be adopted. That is, in the present invention, the transmission of the control command is repeatedly executed as necessary until the preset fixed time elapses after the control command is transmitted to the remote control lighting device B,
When a normal response signal is not returned by the elapse of the certain time, it may be determined that the remote control lighting device B is abnormal regardless of the number of response abnormalities (corresponding to claim 3). . In this case, by storing the address data of the remote control lighting device B having an abnormal response in the RAM at the time when the fixed time has timed out, the control command to the remote control lighting device B having the abnormal response is stored. It is possible to avoid transmission appropriately.

[0025]

As can be understood from the above description, according to the remote control lighting control device of the present invention as set forth in claims 1 to 3, a normal response signal is not returned in response to the transmission of the control command. Since it is possible to avoid unnecessary control commands being repeatedly transmitted to the remote control lighting device, it is possible to effectively and appropriately control the normally operating remote control lighting device in real time.

Particularly, according to the present invention as set forth in claim 2,
It is not judged that the remote control lighting equipment is malfunctioning even if the response abnormality occurs only once due to the mixing of noise, etc., so that the determination becomes accurate, and when the response abnormality occurs twice, the next control command is promptly performed. Since it is possible to shift to the issuance of the remote control lighting device, it is possible to more thoroughly eliminate the waste of time required for controlling each remote control lighting device.
