Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal address setting method for a remote control device that calls a terminal device from a main operation panel and performs remote control using time division multiplex transmission.

FIG. 1 shows a schematic configuration of a remote control system using the present invention. In the figure, 1 is a main operation panel. From this main operation panel 1, for example, a start pulse, address data, control data, return waiting time, etc. are transmitted cyclically. A control signal consisting of pulses etc. is cyclically transmitted to each terminal device 3 through the signal line 2 to control the terminal device 3 of the called address, and also during the return waiting period corresponding to the return waiting period pulse. The terminal device 3
A return signal is sent from ... to the main operation panel 1. As for the terminal device 3..., the user changes the address setting and sends back to the main operation panel 1 the control terminal device during load, which needs to correspond to the usage status, and the data for controlling the control terminal device. A terminal such as a sub-operation panel that transmits signals and controls the control terminal via the main operation panel 1, or a terminal such as a fader panel that transmits dimming data as a return signal to the main operation panel 1. The control terminal is equipped with an address setting switch for changing the address. The other terminal device is similarly provided with an address setting switch, but it is normally fixed at a predetermined address during manufacture.

By the way, the terminal device 3 has a built-in, for example, 8-bit microcomputer for performing arithmetic processing. A method is used to classify 8-bit (1 byte) data using 2-digit hexadecimal numbers, so conventional terminals 3... also use 01, 01,
02, 03,…, 0A, 0B, 0C,…, 0F, 10, ~1F,
Since the address setting switch SW of the 2-digit hexadecimal converting digital switch (shown in Figure 2 a) is used to set the address with a hexadecimal number such as 20, the address must be changed depending on the usage situation. In the case of control terminals, the drawback was that general users were familiar with hexadecimal numbers, making it difficult to configure settings.

In addition, as shown in Figure 2b, an address setting switch SW consisting of a depth switch is sometimes used, but in this case, the setting is based on a binary system, so it is inconvenient to set the address as in the case described above. .

The present invention has been made in view of the above-mentioned drawbacks.
The purpose of this is to use a remote controller that can set the address of a terminal device that requires an address change in decimal notation, which is used on a daily basis, and can handle data in hexadecimal notation, which is easy to distinguish between 8-bit data. provides a terminal address setting method.

This will be explained below using examples. Figure 3 shows the circuit block of the control terminal 3, and 4 in the figure is the CPU.
This logic control unit 4 is a logic control unit consisting of
inputs the control signal from the main operation panel 1 input from the signal input terminal SIG to the address discriminator 6 through the control signal discriminator 5, and inputs the address data of the signal to the input from the address setting terminals AD ₁ to _{AD 8} . Then, compare it with the set address to determine whether or not they match, and if they match, read the control data following the address data and determine the content of the data,
A load control signal corresponding to the determination content is outputted from the control signal discriminator 5 to the output section 7, and the load is controlled through the output section 7. The logic control unit 4 also has a control function for transmitting the monitoring data input from the monitoring input terminals IN ₁ to IN ₅ as a return signal to the signal line 2 through the monitoring input return unit 9 during the input period of the return waiting pulse. It is something. In the case of a device used as a sub-operation panel or the like, data from a keyboard or the like is input to monitoring input terminals _IN1 to _IN5 . In the figure, numeral 10 is an oscillation circuit that generates signals that are the basis of clocks and return signals.

By the way, 8-bit address data is input to address setting terminals _AD1 to _AD8 . That is, the address setting terminals AD ₁ to _{AD 8} are usually the lower 4 bits of 8 bits,
The hexadecimal digital switch is connected so that the binary output of the hexadecimal digital switch, in which each of the upper 4 bits corresponds to one digit, is input, but in the present invention, the address can be changed as described above. The address of the control terminal 3, which is done according to the usage situation, is assigned to an address expressed by the same decimal number, and the address setting terminals AD ₁ - AD ₄ and AD ₅ - of these control terminals are assigned. Address setting switches SW ₁ and SW ₂ consisting of decimal digital switches are connected to AD ₈ , respectively.
It is now possible to set addresses that only correspond to decimal representations, such as 19,... On the other hand, the remaining addresses expressed in hexadecimal numbers are assigned to terminals 3 corresponding to sub-operation panels, fader panels, etc. that do not require address changes, and these addresses are fixedly set at the manufacturing stage.

The main operation panel 1 stores the addresses of these terminals 3, sequentially accesses the terminals 3 at each address, and sends and receives control signals and return signals. FIG. 4 shows a circuit block diagram of the main operation panel 1. In this main operation panel 1, based on the operation data from the operation section 11, the calculation section 12 sends control data to the terminal device 3 at a predetermined address. A control signal is created correspondingly and sent to the signal line 2 as a control signal through the waveform shaping circuit 13 and the waveform amplification circuit 14, and the return signal sent via the signal line 2 is detected by the return signal detection circuit 15 and sent back. The calculation unit 12 takes in the data through the signal input circuit 16, determines the data content of the return signal, and if it is a return signal from the terminal device 3 such as a sub-operation panel, the program and the address of the terminal device 3 are stored in advance. Data contents are written to the storage unit 17 consisting of ROM and RAM, etc., and based on this data, a control signal is created when the control terminal device 3 at a predetermined address is accessed, and a control signal is generated by a return signal from the control terminal device 3. If so, the operating state of the control terminal 3 is displayed on the display unit 18. Shang 19
20 is a power supply unit, and 20 is a clock unit. This clock unit 20 provides time data and timer control data to the calculation unit 12. The time data is data for displaying the time on the display unit 18, and the timer control data becomes the timer control data of the control terminal 3. It goes without saying that the present invention can also be applied to cases where a decimal number other than a hexadecimal number is used for address setting.

The present invention enables the address setting to be changed in a remote controller in which the address of each terminal is set in a base number greater than a decimal number, and the terminal is remotely controlled in response to the calling of the address from the main operation panel. Separate terminal devices and terminal devices with fixed addresses at the time of manufacture, and change the address setting means provided in terminal devices whose address settings can be changed to a setting means that can only set addresses expressed in decimal numbers. , corresponding 10
Addresses other than addresses that can be set using hexadecimal representation are assigned to terminal devices whose addresses are fixed at the time of manufacture, so for example, 8-bit
Even when using a CPU, address settings on the user side can be done in decimal numbers, which are commonly used, making address settings easy. Since addresses are set in decimal notation, including the number of addresses set in hexadecimal notation, the effect is that a digital switch with fewer digits can be used to set a larger number of addresses than when setting addresses in decimal notation. play.
