Abstract

PURPOSE:To synchronize display with broadcasting without requiring operator's consciousness by synchronizing a display instruction to an auxiliary mark plate with a transmission instruction to a transmitter. CONSTITUTION:When an operator instructs the start of sound broadcasting from a message editor 16, the editor 16 transfers the instruction information to a control device 18. The control device 18 applies the transmission instruction of the transmitter 26 to an I/O part 22b, a control part 22c and a transmission part 22d in a broadcasting output switching device 22 through an I/O IF part 18a and transfers a digital sound signal stored in a sound signal quantizing device 22a to a digital recording/reproducing machine 22e through a bus IF part 18b. The digital recording/reproducing machine 22e converts the digital sound signal into an analog sound signal and transfers the analog signal from a line transmission part 22f to the transmitter 26. Simultaneously the control device 18 transfers the display of display contents to the auxiliary mark plate to an auxiliary mark plate control device 14 and instructs its display to synchronize the display with the broadcasting.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road condition broadcasting system called highway radio for broadcasting road conditions such as highways.

[0002]

2. Description of the Related Art FIG. 2 shows the configuration of a conventional road condition broadcasting system. In FIG. 2, 2 is an information exchange processing device for collecting road information and organizing it as event information, 4
Is an auxiliary signboard control device for controlling the auxiliary signboard for displaying an outline of the contents being broadcast, and 6 is a message editor for editing the text to be broadcast based on the event. 8 is an information exchange processing device 2, a message editor 6,
It is a control device that communicates with the auxiliary signboard control device 4 and performs synchronous control.

Further, 10 is an operation console for an operator to input a voice and further instructs to start broadcasting, 12 is a broadcast output switching device for performing analog / digital conversion of the operator's voice and controlling the switching of the transmission, 16 Is a transmitter for transmitting road condition information by radio waves, and 18 is an antenna.

Next, the operation of this configuration will be described.
Event information relating to road information is transferred from the information exchange processing device 2 to the control device 8. The control device 8 sends the transferred event to the message editing machine 6 and instructs the text editing based on the event. The message editor 6
When the text editing is completed, the operator is notified by a lamp or a buzzer that the editing is completed. When the operator confirms the text contents on the CRT display of the message editor 6 and instructs the auxiliary sign board controller 4 to start displaying the summary of broadcast contents, the message editor 6 sends the display instruction information to the controller 8. Forward. The control device 8 transfers the display content on the auxiliary signboard to the auxiliary signboard control device 4 and instructs the display. Further, the operator inputs the confirmed sentence by voice from the microphone 10a of the console 10 at the same time as the display instruction to the auxiliary sign board is made. The analog audio signal input thereafter is digitized by the audio quantizer 12a in the broadcast output switching device 12 and stored.

Next, the operator turns on the broadcast start switch 10b of the console 10 to turn on the broadcast output switching device 12
A signal is supplied to the input / output unit 12b and the voice quantizing device 12a. With this signal, the input / output unit 12b, the control unit 12c, and the transmission unit 12d of the broadcast switching control device 12 are transmitted to the transmitter 1
6 is controlled to a transmittable state, and the voice quantum device 1
The digital audio signal stored in 2a is transferred to the digital recording / reproducing device 12e, where it is converted into an analog audio signal, and the audio signal is transferred from the line transmitter 12f to the transmitter 16. The transmitter 16 transmits this voice on an expressway through an antenna 18.

[0006]

By the way, in the conventional road condition broadcasting system, the operation for the operator to give a display instruction to the auxiliary signboard control device 4 and the operation for blowing a message from the microphone 10a of the console 10 are always consecutive. If this is not done, the display and broadcast timings will be significantly different. Further, even if the operations are continuously performed, the display and the broadcast are out of sync with each other from the time when the operator starts the operation of blowing into the microphone 10a to the time when the broadcast start switch 10b is pressed (about 2 to 3 minutes). There is a drawback that the content displayed on the auxiliary signboard and the content broadcast on the expressway differ.

The present invention is to solve such a conventional problem, and the display instruction to the auxiliary signboard and the transmission instruction to the transmitter are synchronized, and the display and the broadcast are displayed without the operator's awareness. The purpose is to provide an excellent road condition broadcasting system that can be matched.

[0008]

In order to achieve this object, the road condition broadcasting system of the present invention comprises an auxiliary sign control means for controlling the display of an auxiliary sign for displaying the road condition, and a start of audio broadcasting. A message editing means for transferring instruction information, a transmitting means for wirelessly transmitting an input analog voice signal, and a digital voice signal are stored, and
It has a broadcast output switching means for transmitting the digital audio signal stored under control, a bus interface part connected to the broadcast output switching means, and an input / output interface part. Control means for giving a transmission instruction to the transmission means, further sending an analog audio signal from the broadcast output switching means to the transmission means, giving a display instruction to the auxiliary sign control means, and performing synchronous control of the display instruction and the transmission instruction. And with.

Further, the broadcast output switching means is provided with an audio quantizer for storing a digital audio signal and a digital sound recording / playback unit for converting the digital audio signal into an analog audio signal and transmitting the analog audio signal. Is.

[0010]

Therefore, according to the road condition broadcasting system of the present invention, the man-machine interface for the operator to instruct the start of broadcasting from the message editor is provided, and the control device and the broadcast output switching device are provided as the input / output I / F section. Since the control device controls the display start instruction to the auxiliary signboard control device by connecting with the bus I / F section, and the control device instructs the broadcast output switching device to start broadcasting, The display instruction to the auxiliary signboard and the transmission instruction to the transmitter are synchronized, and the display and the broadcast can be matched without the operator being aware.
