Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for remotely controlling a driving device such as an automobile or a robot, and more particularly to a remote control system suitable when it is necessary to simultaneously control a plurality of driving devices at the same place.

[0002]

2. Description of the Related Art When a plurality of driving devices are remotely operated using infrared rays or radio waves in the same place, signals from transmitters provided corresponding to the respective driving devices interfere with each other and accurate control is difficult. May be. As a technique for solving such a problem, for example, a system disclosed in Japanese Patent No. 2625617 is known. In this system,
Different identification data is set for each of the plurality of transmitters, and the same identification data as that of the corresponding transmitter is set for each receiver. The transmission data from each transmitter has a data part corresponding to the actual control information, a unit data part consisting of a space part having a time length longer than the sending time of the data part, and a unit data part having a length longer than the unit data part. It is composed of a combination with a weight part having a time length.
The combination of the unit data part and the weight part is changed according to the identification data assigned to each transmitter.
This creates a state in which the data parts transmitted from each transmitter do not overlap each other.

[0003]

In the above remote control system, the transmission timing of the data from each transmitter is not controlled in particular so that each transmitter responds to its own identification data. The data is transmitted according to the transmission pattern. For this reason, when the number of transmitters increases, the frequency at which the transmission times of the data from the transmitters overlap each other significantly increases, and the probability that the data will be transmitted from only one transmitter decreases. This may make it difficult to smoothly control each driving device. Such confusion is likely to occur, especially when it is required to continuously operate a large number of drive devices.

[0004] Therefore, an object of the present invention is to provide a system or the like which can smoothly remotely operate a plurality of driving devices at the same place.

[0005]

The present invention will be described below. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated forms.

The remote control system of the present invention is a system in which a plurality of drive devices (1 ... 1) are individually controlled by a plurality of transmitters (2 ... 2) prepared in association with them. In each of the plurality of transmitters, identification information unique to each transmitter for identifying each transmitter,
Data transmitting means (3, 14) for transmitting data including control information for controlling the driving device, and receiving means (5, 1) for receiving data transmitted from another transmitter.
6), timing setting means (10) for setting the transmission timing of its own data based on the identification information included in the received data, and causing the data transmitting means to transmit the data in accordance with the set timing. A transmission control means (10) is provided, and each of the plurality of drive devices has a reception means (34, 35) for receiving transmission data from each transmitter, and an identification information included in the received data. Compared to the identification information assigned to
The control means (37) for judging whether or not the received data is the data transmitted to itself and executing the operation control based on the data when it is judged to be the data for itself is provided with the above-mentioned. It solves the problem.

According to this remote control system, since each transmitter can receive the data transmitted from another transmitter, the transmitters can mutually adjust the transmission timing. Therefore, it is possible to prevent the data interference by setting the transmission timings of the data from the respective transmitters so as to be shifted from each other. Accordingly, even when a plurality of transmitters are used at the same time, the driving device corresponding to each transmitter can be smoothly operated remotely.

In the present invention, the driving equipment includes various moving bodies such as vehicles, robots, animal toys and the like. The present invention can be applied to the case where different parts of a single object are remotely controlled by a plurality of transmitters as different driving devices. As the transmitter, one that transmits a control signal or the like using various transmission waves such as infrared rays and radio waves can be used.
For example, an identification number can be used as the identification information assigned to the transmitter and the driving device.

The remote control system of the present invention may include the following aspects.

[0010] The period in which each transmitter can transmit data within a predetermined period is predetermined based on the identification information assigned to each transmitter so that they do not overlap with each other, and the timing setting means sets the timing setting means from other transmitters. When the transmitted data is received, the transmission control means specifies the time until the period within which the data can be transmitted reaches itself based on the identification information included in the data. The transmission of data by the data transmitting means may be started at the time when the predetermined time has elapsed.

With this setting, each transmitter can specify the timing at which it should transmit data by utilizing the transmission of data from other transmitters. Moreover, since the data transmission of each transmitter is performed every predetermined period, even if some transmitters interrupt the data transmission in the middle, the remaining transmitters transmit the data at the time when they are assigned to themselves. can do.

[0012] The period during which each transmitter can transmit data within the cycle may be set to be equal to each other for each transmitter. By doing so, it is possible to specify the period during which each transmitter can transmit its own data only by predetermining the order of data transmission of each transmitter within a predetermined cycle. That is, assuming that the time length of the transmission period given to each transmitter is T, when the data transmission from the transmitter having the earliest transmission order is started, the transmitter having the next transmission order is started. May start transmitting after time T, and the next transmitter may start transmitting after 2T. In this way, if the transmission start time of one transmitter is known, the transmission timing can be easily specified from the transmission order and time assigned to each transmitter.

The timing setting means sets the transmission timing of the data so that the own data transmitting means repeats the transmission of the data at the predetermined cycle when the data from the other transmitter cannot be received. Good. In this case, even when the data transmission from all the transmitters except the self is stopped, the self can repeatedly transmit the data at the correct timing.

It is determined whether or not the identification information included in the data transmitted from another transmitter is the same as the identification information set for itself, and if it is the same, the identification information different from itself is included. Each transmitter may include a holding means (10) for holding the setting of the transmission timing by the timing setting means until the data is received. In this case, it is possible to prevent interference when the identification information is duplicated in a plurality of transmitters.

The data transmitted at the timing set by the timing setting means and the data received in parallel with the transmission are compared, and when the two data do not match, the holding means executes the transmission. Each transmitter may be provided with a data confirmation means (10). In this case, it is possible to detect interference as a result of simultaneous data transmission from other transmitters and adjust the data transmission timing so that such interference does not reoccur.

The front wheel 23 is rotatably attached to the support leg 25 via an axle 25a. The support leg 25 is rotatably attached to the chassis 21 about a vertical turning shaft 26. As a result, the front wheel 23 can freely rotate 360 ° about the turning shaft 26. Dummy wheels 27, 27 are attached to the left and right of the front part of the chassis 21, but the dummy wheels 27 are floating and the chassis 21 is supported by the front wheels 23 and the rear wheels 24, 24.

A pinion 29 is attached to the output shaft 28a of each motor 28, and the rotation of the pinion 29 is transmitted to the rear wheel 24 to be driven via the gear train 30. Since the left and right rear wheels 24, 24 are independently driven by the motors 28, 28 in this manner, the rotation speed of the motors 28, 28 is changed left and right to drive only one of the motors 28, or By rotating 28 in different directions, various turning motions can be given to the automobile model 20.

An LED 33 for determining whether or not the power is turned on is provided on the rear portion of the chassis 21. Further, in the upper center of the body 22, a remote control signal light receiving portion 3 for receiving infrared rays from the transmitter 2 is received.
4 are provided.

FIG. 5 shows a circuit configuration of a control system mounted on the automobile model 20. The vehicle model 20 is provided with the remote control signal light receiving unit 34 described above. The remote control signal light receiving unit 34 receives the infrared light transmitted from the transmitter 2, and outputs a signal obtained by removing the carrier component from the received infrared light to the receiving circuit 35.

One block of remote control data is as shown in FIG. The control circuit 37 determines the identification number of the reception data given from the reception circuit 35, compares the identification number with the identification number set by the identification number setting switch 38, and determines whether the remote control data is valid or invalid. To do. That is, if the identification numbers do not match, the received remote control data is determined to be invalid and the drive signal for the motor 28 is not generated.

It may be one. In addition,
A power switch 40 is also connected to the control circuit 37. Figure 4
The battery 31 and the LED 33 shown in are omitted in FIG.

In the vehicle model 20 as described above, when the remote control data is transmitted from two or more transmitters 2 at the same time and the identification number of one remote control data is the same as that of the vehicle model 20, Since the control circuit 37 considers the received remote control data as valid, the control information of the motor may interfere with the control information from another transmitter 2 having a different identification number, and the motor 28 may be erroneously controlled. Therefore, in the remote control system of the present embodiment, each transmitter 2 determines the timing at which it can transmit while receiving the remote control signal emitted from another transmitter 2, so that the transmission timing of each transmitter 2 is duplicated. The transmission timing is synchronized so that it will not occur. Hereinafter, this point will be described.

FIG. 6 shows how to set the transmission timing when the four transmitters 2 are used at the same time. Figure 6
In the above, the time length for one transmitter 2 to transmit the remote control signal is T, and each transmitter 2 transmits the remote control signal at a cycle corresponding to the number of transmitters 2 × transmission time length T (= 4T). repeat. Also. The transmission timing of each transmitter 2 is sequentially shifted by T from the identification number 1. By controlling the transmission timings of the respective transmitters 2 according to such a relationship, it is possible to prevent the transmission timings of the four transmitters 2 from overlapping each other. In order to realize such transmission control, for example, in the transmitter 2 having the identification number 2 in FIG. 6, the transmission timing may be controlled as follows.

First, when the data of the identification number 1 is received at time t1, the output of its own transmission data is subsequently started, and the output of its own transmission data is completed at time t2. Upon completion of transmission, the reception data of the reception circuit 16 (see FIG. 2) is checked to confirm that signal interference has not occurred. After this, the transmission timer for counting the next output timing is set after 3T, and the timer count is started.

When the remote control data of the identification number 3 is received at time t3, the transmission timer is reset after 2T and the timer count is started. When the remote control data of identification number 4 is received at time t4, the transmission timer is reset after T,
Start timer count.

After that, if the transmitter 2 with the identification number 1 is turned off, or if the data from the transmitter 2 with the identification number 1 cannot be received due to noise or the like, after receiving the data with the identification number 4. The output of one's own data may be started at the time when the transmission timer counts by the time T.
Even when the signal from another transmitter 2 cannot be received, the output of the transmission data can be continued at the cycle 4T by utilizing the time 3T set in the transmission timer when the transmission of the own data is completed.

Although the case where the number of transmitters 2 is 4 has been described here, the transmission timing can be controlled in the same manner even when the number of transmitters is 5 or more by adding an identification number. The transmission timing cycle of each transmitter 2 is N × T (N
Is the number of transmitters). However, a blank period in which no transmitter is transmitting data may be interposed between the periods in which the transmitters 2 are transmitting data, thereby setting the entire cycle longer than NT. .

FIG. 7 is a flow chart showing the procedure of the power-on operation which is executed by the control circuit 10 of the transmitter 2 from the time when the power is turned on to the time when the own data is transmitted. When the power is turned on, first, a timer for time over is set (step S1). Next, it is determined whether or not data from another transmitter 2 has been received (step S2), and when received, the identification number of the received data is the transmitter 2 of its own.
It is determined whether or not it is the same as the identification number set for (step S3). If they match, the process returns to step S1 to repeat the determination operation. This prevents interference when there are a plurality of transmitters 2 having the same identification number.
When it is determined in step S3 that the identification numbers do not match, the own output timing is set according to the identification numbers of the other transmitters 2 (step S4). For example, in FIG.
When the transmitter 2 having the identification number 2 receives the data having the identification number 3, the own output timing is set after 2T time.

Then, it is judged whether or not the timer set in step S1 has timed out (step S1).
5) If the time is not over, return to step S2.
When the time is over, transmission of its own data is started (step S6). However, the output is actually started when the output timing set in step S4 arrives. If no data is received by the time out, it means that there is no other transmitter, that is, there is no other transmitter, so that the data transmission is immediately started in step S6.

When the process of step S6 is completed, the control circuit 10 controls the data transmission according to the procedure of the normal operation of FIG. In normal operation, first, it is determined whether or not data from another transmitter 2 is received (step S11), and if it is received, it is determined whether or not the identification number matches the identification number set for itself. (Step S12). If they match, the process returns to the power-on operation of FIG. On the other hand, if the identification number of the received data is different from its own identification number, its own output timing is set in the transmission timer according to the identification number of the received data (step S13). Next, it is determined whether or not the transmission timer has timed out (step S
14) Return to step S1 until the time is up.

When it is determined that the time is up in step S4, the transmission of its own data is started (step S15). At this time, data is also received in parallel. Next, it is determined whether or not the data transmission is completed (step S16), and if the transmission is completed, the transmitted data is compared with the data received in parallel with the transmission (step S17). If they do not match, it is determined that interference has occurred, and the process proceeds to the power-on operation of FIG. If they match, it can be considered that there is no interference, so the next output timing is set in the transmission timer (step S18). Then, step S1
Return to.

The present invention is not limited to the above embodiments and may be implemented in various forms. For example, the driving device is not limited to an automobile, and may be a model imitating various moving bodies. The transmitter may be handheld by an operator or may be a stationary type. A specific program may be installed in a portable device such as a portable game machine or a mobile phone to function as a transmitter.
