Abstract

PURPOSE:To provide communication control equipment in which the reception pull-in and the reception rate of wire reception are improved by transmitting radio data received continuously to a wired line after substituting a bit synchronizing pattern for its ineffective data part. CONSTITUTION:The radio data 1 from a radio transmitter is received by a radio data receiving part 2, and is inputted to a synchronizing detector 3. The synchronizing detector 3 detects bit synchronization and frame synchronization from a radio data string, and sends synchronous reproduced data and detected result information to a switching output part 5. The switching output part 5 transmits the synchronous reproduced data to the wired line 6 if a detected result is good, and if not good, it switches the synchronous reproduced data to the bit synchronizing pattern generated by a bit synchronizing pattern output part 4, and transmits it to the wired line 6.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relays wireless data,
The present invention relates to a communication control device that transmits data to a remote place using a wired line.

[0002]

2. Description of the Related Art Conventionally, a communication control device of this type reproduces wireless data only by detecting bit synchronization, or reproduces only normal data by a reception frame synchronization verification and transmits the data to a wired line.

[0003]

However, in the above-mentioned conventional communication control device, the invalid data portion of the wireless data is output to the wired line as it is or is used as the mark hold.

The present invention is to solve such a conventional problem, and replaces the invalid data portion of continuously received wireless data with a bit synchronization pattern and sends it to a wired line to receive wired reception. An object of the present invention is to provide a communication control device capable of increasing the pull-in speed and improving the data reception rate.

[0005]

In order to achieve the above object, the present invention detects a quality of received wireless data and outputs a reproduction data and a detection result of the quality, and a bit synchronization pattern. A bit synchronization pattern output section
Based on the detection result of the detection unit, normal data is sent to the wired line, and if it is not normal data, it is equipped with a switching output unit that switches to the output of the bit synchronization pattern output unit and sends it to the wired line. is there.

[0006]

Therefore, according to the present invention, the quality of the wireless data is detected by the detection unit, and the reproduction data and the detection result of the quality are sent to the switching output unit. The data is transmitted to the wired line, and if it is not normal data, it is switched to the output of the bit synchronization pattern output unit and transmitted to the wired line. In this way, in the data string on the wired line, the bit synchronization pattern is embedded except for normal data.

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram showing a communication control device according to an embodiment of the present invention. In FIG. 1, 1 is wireless data transmitted from a wireless transmission device, 2 is a wireless data receiving unit for receiving wireless data 1, and 3 is bit synchronization from a bit string of wireless data 1 received by the wireless data receiving unit 2. , A sync detector for detecting the frame sync and sending out the detection result and the sync reproduction data, 4 is a bit sync pattern output section for generating a bit sync pattern,
A switching output unit 5 selects the output signals of the synchronization detector 3 and the bit synchronization pattern output unit 4, switches them, and outputs them to the wired line 6.

The operation of the above arrangement will be described below. The wireless data receiving unit 2 receives the wireless data 1 transmitted from the wireless transmission device, and inputs the wireless data 1 to the synchronization detector 3. The sync detector 3 performs bit sync detection and frame sync detection from the input wireless data string, and sends the data reproduced synchronously and the quality of the detection result to the switching output unit 5. If the result is good, the switching output unit 5 outputs the data reproduced synchronously from the sync detector 3 to the wired line 6 if the result is good in accordance with the information on whether the detection result is good or bad. On the other hand, if the detection result is negative, the switching output unit 5 switches to the bit synchronization pattern from the bit synchronization pattern output unit 4 which is always input and outputs it to the wired line 6. In this way, in the data string on the wired line 6, the bit synchronization pattern is embedded except for normal data.

[0010]

As described above, according to the present invention, when the quality of the wireless data is detected by the detection unit and the reproduction data and the detection result of the quality are sent to the switching output unit, the switching output unit detects the normal data. In this case, this is transmitted to the wired line, and in the case of other than normal data, it is switched to the output of the bit synchronization pattern output unit and transmitted to the wired line. When wireless data is normally received in this way, the regenerated wireless data is sent to the wired line, and the bit synchronization pattern is sent to the wired line when there is no reception or incorrect data. Otherwise, the bit synchronization pattern will be embedded. Therefore, in the wired receiving device connected to the other end of the wired line, the bit synchronization pull-in becomes faster and the illegal data is not sent out, so that the error reception is reduced.
