Abstract

PURPOSE:To improve the reliability by adding a supervisory pattern in a control information word sent from a sender side to a receiver side as the telecontrol system in which remote control by a remote controller is implemented. CONSTITUTION:An input section 2 at a sender side adds a regular pattern to a control input and adds a parity to the pattern. A check section 13 at a receiver side confirms the pattern sent from the sender side and checks the parity and when the pattern is normal, an output control section 14 outputs control information and when the pattern is in error, the control section 14 locks the control information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern teleconverter control system, and more particularly to a pattern teleconverter control system in which an error verification function is added to a teleconverter control (remote control) in a remote control device.

[0002]

2. Description of the Related Art In a conventional teleconverter control system of this type, as shown in FIG. 2, one bit of control information of 1 bit is divided into two signals in two signals in order to increase the reliability.
The remote control device receiver 11 and the output unit 12 at the receiving end, which have transmitted the control information from the remote controller transmitter 1 and have received this control information through the transmission path 101, output two signals as they are, and control these two signals. I checked and output the AND condition of the information.

According to this method, if an error of 2 bits or more occurs in one control information on a transmission line or the like, it is determined as erroneous control.

[0004]

In the conventional teleconverter control system for transmitting one control information as two signals, the two signals to be controlled are simultaneously transmitted due to the quality deterioration of the transmission line and the hardware trouble of each part. If it is inverted, there is a problem that erroneous control output or control output is not performed.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a pattern-equipped teleconverter control method capable of always ensuring an erroneous control output or control output and significantly improving reliability.

[0006]

According to the method of the present invention, in a teleconverter control method for performing remote control in a remote control device, control information for remote control is transmitted from a transmission end opposed to a reception end via a transmission line. A rule pattern for monitoring is added in the word, and the receiving end checks the control information word including the rule pattern at the time of reception to ensure improvement in reliability of remote control.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. In the embodiment shown in FIG. 1, a remote control device 1, an input unit 2, a transmission end provided with a pattern addition unit 3 for adding a monitoring pattern to transmission data, a remote control device 11, and an output unit 1.
2, a verification unit 13 that performs an error test of the received data based on the pattern added on the transmission side, and an output control unit 14 that controls the transmission of the control output based on the result of the error test of the verification unit 13, The transmission line 101 is also shown.

Next, the operation of this embodiment will be described.

The control input is input to the nth bit of the first word and the mth bit of the second word of the input section 2. This control input is also input in parallel to the pattern adding section 3, and the parity judgment is performed according to the condition with the rule pattern.

From the pattern adding section 3, a regular pattern,
A parity signal based on the parity determination is input to the input unit 2. That is, the control information, the rule pattern, and the parity signal are input to each of the first and second words.

The input information is converted into a serial signal by the remote control device transmitting section 1 and transmitted to the remote control device receiving section 11 via the transmission path 101.

The output unit 12 outputs the control output, the regular pattern and the parity signal in the same arrangement as the input unit 2 on the transmission side.

The verification unit 13 receives the rule pattern and checks the comparison with the pattern transmitted from the transmitting side. Similarly, the parity judgment is also performed, and if normal, the gate of the output control unit 14 is opened to enable the output operation. If it is abnormal, the gate of the output control unit 14 can be closed to lock the operation of the control output, thus significantly improving the reliability of the remote control device.

The above-described teleconverter control system with a pattern can be set by a hard wire of an individual component of the remote control device, and can be realized with a simple hardware configuration.

[0015]

As described above, according to the present invention, the range from the transmission end to the reception end in the remote control device is included in the range of the rule pattern and the parity addition, and the reception end is provided with the check function and the output lock function at the time of abnormality. Thus, there is an effect that the reliability can be significantly improved.
