Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control system for remotely controlling many loads.

[0002]

2. Description of the Related Art As a remote control system for centrally managing many loads, there is, for example, a lighting monitoring control system. In this lighting monitoring and control system, the load to be monitored and controlled is a lighting device, and many indoor and outdoor lighting devices are turned on / off or dimmed for centralized management. In such a lighting monitoring control system, a master unit that controls or monitors the operation of a load, and a plurality of units that receive a control signal or a monitoring request signal transmitted from the master unit and operate a load corresponding to the signal content are received. A lighting device, which is a load, is connected to each of the slave units.

[0003] Data transmission between a master unit and a slave unit is performed by wireless transmission. That is, one master unit antenna is provided in the master unit, and one slave unit antenna is also provided in each slave unit, and data is transmitted and received between the master unit antenna and the slave unit antenna. In this case, the control signal and the monitoring request signal from the master unit are sent only once, and the monitoring data from the slave unit in response to the monitoring request signal is sent only once.

When a plurality of loads are connected to the slave unit, when a control signal or a monitoring request signal is wirelessly transmitted from the master unit, the wireless I / F units having different frequencies are used to transmit the respective systems. Data was transmitted to identify multiple systems.

Further, a control signal and a monitoring request signal wirelessly transmitted from the master unit to the slave unit are input from the console to the master unit in a predetermined signal format, and the signal format is transmitted wirelessly by the master unit. You. Then, the signal content received by the slave unit is transmitted to the load in a format similar to the format input from the console.

[0006]

However, in such a lighting monitoring and control system, when there is an obstacle between the installation position of the master unit and the installation position of the slave unit, a radio signal transmitted from the master unit is generated. There is a case where it is not possible to receive at the slave unit.

Also, the position of the obstacle is not fixed, and the obstacle may move. For example, in a lighting monitoring and control system in a studio, a slave unit equipped with a lighting device may be moved,
In such a case, a wireless signal transmitted from the master unit may not be able to be received by the slave unit due to the influence of the position of the surrounding humans and the arrangement position of other devices.

In such a case, if data to be wirelessly transmitted from the master unit is transmitted a plurality of times instead of once, the obstacle may disappear and the slave unit may be able to receive a radio signal.
Moving the handset does not necessarily eliminate the obstacle, so even if the handset is transmitted a plurality of times, the handset may not be able to receive the radio signal transmitted from the base unit. If the slave unit cannot receive the wireless signal sent from the master unit,
Lighting monitoring control cannot be performed smoothly.

Further, when a plurality of loads are connected to the slave unit, each system data is transmitted from the wireless I / F unit having a different frequency to identify the plurality of systems. In addition, there is a problem that a plurality of wireless I / F units having different frequencies are required in the slave unit.

[0010] Further, since the console and the load are processed in a predetermined signal format, signals having different signal formats cannot be processed. That is, since the console outputs a signal of a predetermined signal format, it is possible to replace an already used console with a console having a different signal format or to use a load ( The dimmer and the lighting device) could not be replaced with loads having different signal formats (the dimmer and the lighting device) and there was no flexibility.

An object of the present invention is to provide a flexible remote control system capable of more reliably transmitting a radio signal between a master unit and a slave unit.

The reason for avoiding the overlapping of the transmission times of the transmission data is to avoid the interference of the overlapping radio waves. The time from outputting the control signal to outputting the monitoring request signal corresponding to the control signal is within a time period such that a human does not feel a delay from outputting the control signal to responding to the load. . For example, when the load is a lighting device, a lighting command (light-off command) is issued, and then the light is turned on (light-off).
This is a time that humans do not feel delayed in the time until the task is completed.

According to the third aspect of the present invention, the transmission data from the plurality of master unit antennas is transmitted so that the transmission timings do not overlap, so that they do not interfere with each other.

In some cases, the input data for the first load system (system 1) is temporarily stored in the wireless transmission buffer (S2). Similarly, control unit 7 of base unit 1 determines whether or not there is a signal input to second load system (system 2) from console 11b (S3), and a signal input to second load system (system 2). If there is a parent device 1
