Abstract

PURPOSE:To attain the assured transmission of signals without adding any new wiring by transmitting both a remote control signal and an answer-back signal via a commercial power supply line and sending the control signal to a slave device in response to the stored answer-back signal. CONSTITUTION:The remote control signal S1 is delivered twice at a fixed interval and transmitted to a slave device through commercial power lines 4 and 5. The slave station decodes the code of a transmitted function FU and transmits the answer-back signal S2 to the lines 4 and 5 through a transmission/reception circuit. When the signal S2 is supplied, an address AD and a function FU signal contained in the received answer-back signal are converted into parallel codes. These parallel codes are stored to a memory in a microcomputer 18 and also decoded. Then the display data accordant with the load state of a slave device corresponding to the address data is delivered to a display part 15.

Description

[Detailed description of the invention] (a) Industrial application field The present invention provides centralized control of lighting equipment (hereinafter referred to as "load") in ordinary homes and buildings from a remote location. This relates to a remote control method.

(2) Prior Art This kind of conventional remote control method uses electromagnetic waves as the transmission medium of the remote control transmission signal,
This method used a line created by wiring work between the remote control transmitter and each remote control receiver.

However, in the former case, there is a problem in the reliability of signal transmission, and in the latter case, wiring work is difficult and wiring work is required every time a new remote control receiver is added. Ta.

1. Problems to be Solved by the Invention The present invention ensures reliable signal transmission and remote control operation, and also enables centralized remote control of multiple controlled devices without the need for new wiring work when adding a new remote control receiver. The technical challenge is to obtain a remote control method that can be used.

2) Means for Solving the Problems In order to solve the above technical problems, the present invention provides a plurality of cables connected to a load and assigned unique designation numbers, and controlling the load. One remote control system with one main device that has the function of transmitting the remote control signal to the remote control as well as receiving and storing the answer back signal from the remote control and confirming that the specified control is performed. A control signal is formed in the memory, and the control signal is transmitted closely to the channels in accordance with the stored un-9-A check signal.

(e) Effect The above technical means acts as follows. In other words, the parent device decodes the assister back signal stored in the parent device that corresponds to the chip it is trying to control, and transmits a remote control signal to the chip depending on the operating state of the chip. .

(F) Example: First, if there are a large number of loads to be remotely controlled in a general home or building, the large number of loads can be divided into blocks of up to m, with a maximum of n loads being one block. To divide. Here, n is an integer of 2 or more, and 1m is an integer of 1 or more.

Accordingly, each load is assigned a unique designation number (eg, including a unique block number and a unique address number).

Further, a unique designation number corresponding to the load is also assigned to the remote control receiver (ie, remote controller) that controls each load. Furthermore, the remote control transmitter (i.e., the master unit) for controlling the chi-tightness also has a unique designated number (a unique block number, so if there is only one block, the designated number is not necessarily required for the master unit). ) shall be assigned.

In Figure 1, (1) is the parent device], and at least

It has the function of generating a remote control signal consisting of an address number code and a funk scene hood for operation commands and a parity code, and sending it to the commercial power supply line (41 (51). It has the function of receiving and storing back signals and the function of displaying an echo according to answer back signals.
Only when the remote control signal sent from the device is equal to its own unique block number and unique address number, it receives and operates according to the sent command. In addition, at that time, the code for synchronization with the parent device (11), the code indicating its own unique block number and address number, the pulse hood and parity code indicating its own operating state (for example, on, off) are sent as an answerback signal. The master device (11) is sent to the load (61 (7)).

When the control switches (12a) to (1, 2n) corresponding to the load to be operated on the keyboard (11) are pressed, the microcomputer inputs the address data set in the control switch, and
It decodes the function data in the answerback signal stored in the internal memory that controls the load, and for example, if the function data indicates that the load is in the power ON state, the power is turned off. The OFF command is sent to the IC (as function data) along with the address data.

With the above, the operation of performing remote control from Friendly(11 to +4(2+'i) is completed.

In addition, in Figures 21 and 3, we will explain the parts that are not mentioned in the above explanation. External components constituting a part of the oscillation circuit for giving the signal are components 1, such as a capacitor and a crystal resonator. (38H391 is a power supply circuit that generates the DC voltage necessary for each circuit to operate.

In addition, each IO (19 (251

As soon as the input circuit receives a human input signal from the I terminal, the timing circuit is reset and driven so that the internal state is in the receiving state. Also, when the internal unit is in the transmitting state, signals coming from the %SDI terminal are shut out. Timing generation circuit 161 generates various lock pulses necessary for internal operations.

This is a circuit that stores bit serial reception signals. Comparison circuit (2) compares the signal stored in the shift register 7) with the address code stored in the parallel-in/serial-out shift register, and
Since the same signal is input to the SDI terminal twice, the first and second signals are also compared. The fan decoder 4 is a circuit that decodes the 4-bit code in the received signal and sends its output to the relay control flip-flop Q and the dimming control circuit. This is a circuit that generates a pulse that is delayed by a certain period of time with respect to the zero-crossing pulse of the commercial power supply, which is manually input from the TO terminal. The delay time is determined by the output of the function decoder. The relay control flip-flop is a circuit that outputs "11" or "01" according to the command decoded by the 79-inch decoder, and its output is used as a signal to control the relay.
Output from the terminal. The parallel-in/serial-out register is a circuit that stores transmission signals.

Outputs the signal serially based on the transmission start signal.

Between the parity generation circuits is a circuit that serves to add one parity bit to the output of the shift register. Between the modulation circuits is a circuit that modulates with a transmission signal 'fr120KHz, and this pressure is output from the SDO terminal.

First, the time chart for transmitting this IO- is shown in Figure 7. After the internal circuit is reset by the reset signal (A) given to the R8T terminal, at least 1B is sent to the BT terminal.
When a signal (b) with a pulse width of ms is applied, the timing generation circuit decoy is driven. Then, the parallel data stored in the address terminals AO to A9 and the digital terminals FO to F, which are bidirectional terminals, are read into the parallel in-serial out shift register and converted into serial data (/bar). Serial data after conversion (/
In some cases, a 5-bit parity bit is added between the reader and the parity generation circuit. Therefore, the transmitted data is 111
It consists of 20 bits in total: 5 league bits of 001m, 10 bits of address code, 4 bits of function code, and 1 bit of parity. Note that a part of the address code can be used as the above-mentioned block code. If 1 bit is 250μB, 1 data to be sent will be 5ms,
) is output repeatedly twice. This transmission data is manually modulated at 120KHz to the modulation circuit and converted to 8DO.
(Note that during the transmission operation, input to the EIDI terminal is prohibited, and the own transmission data fr: cannot be received.)
It looks like this.

The basic operation in the case of reception is that when the transmission data is manually input to the 8DI terminal, the signal is input to the input circuit &19'ft: street-i
(13) Manually input to the full-in/parallel-out shift register.At this time, the input circuit drives the timing generation circuit.The timing generation circuit generates various timing signals for performing the reception operation.Next, the input circuit drives the timing generation circuit. When the second transmission data is input to the BDI terminal, it is input to the serial-in/parallel-out shift register in the same way as the previous time.

At this time, a comparison circuit compares whether the 17-da is "11QQI'" and whether the first data and the second data are the same. At this time Il

also performs a parity check.

If there is no error in the above data discrimination operation and the addresses match, the received data input to the serial/mono/parallel out shift register η is transferred to the I10 terminal AO~
At and F go out to OS-F'6.

At this time, the DR (data ready) terminal becomes “1”,
Indicates that AOS-A9 and FO to F3 are in the output state. Also, when the DR terminal is at "1 degree", 8DI manual input is prohibited, and even if a signal is input to SDI in that state, it will not be accepted and the previous data will be retained.The R8T (reset) terminal will set "1". When inputting , the inhibited state of the SDI terminal is canceled, the DR terminal becomes "0'", and the I10 terminal also returns to the input state.

Note that input to the BT (start) terminal is prohibited during reception operation.

In the case of reception mode, set the M1 and M2 terminals to m11 and "01" respectively (when used as a +6 IC as shown in Figure 3), and following the above reception operation, the function code of the reception data is The indicated command is decoded by the 71-link decoder 4, and the result is transmitted to the dimming control circuit and the relay control flip-flop I2.

The dimming control circuit ■ is a circuit that generates a pulse that is delayed by a certain period of time with respect to the zero-crossing detection pulse of the commercial power supply input to the AC terminal.
Can be controlled in stages.

In the case of reception mode, the Ml and M2 terminals are respectively m01 and a1+'' [when used as Xa of the device as shown in Figure 2], and the reception address input to the SDI terminal in addition to the basic reception operation described above. The code is compared with the address code set in 80 to A9 using only the upper 5 bits, and if they match, the data is considered receivable.
The operation commanded by the function code in the received data is not performed, and the received data FO to FB and RO,T are processed.

It has nothing to do with the terminal. The RO terminal always outputs a 701° pulse, and the To terminal outputs a 480 KHz pulse. Input “1” to the AO terminal.

(g) Effects of the Invention According to the present invention, since the remote control signal and the answerback signal are transmitted using the commercial power line, a new load to be controlled and a +6 (remote control receiver) are required. Even if the number of devices increases, there is no need for extensive wiring work for remote control, and signal transmission can be ensured. In addition, the answer pack method is used to make it possible to confirm whether or not a proper control operation has been performed, improving the reliability of remote control. Since the load and +6 are operated, the number of switch contacts can be reduced to one for each load and +6, and the number of parts can be reduced.
