Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to controlling the display operation of an in-vehicle display of a route bus included in a route bus operation management system.

(Prior art and its problems) FIG. 11 is a systematic diagram of a conventional route bus operation management system. In FIG. 1, reference numeral 1 denotes a route bus operation control device that centrally manages and controls the operation of route buses, and 2 denotes a roadside communication device connected to this route bus operation control device 1 through a separate communication line 3. It is. 4 is a route bus, and this route bus 4 includes an on-board communication device 5 that transmits and receives transmission data from the on-road communication device 2 using radio waves, and this on-board communication ff.
An in-vehicle display 6 that displays communication contents from 16 is installed.

Figure 2 shows each route 7°8.9 of roadside communication device 2 and route bus 2.
It is a figure showing a garage 10. Route 7 of @1 is a solid line,
The second route 8 is indicated by a chain line, and the third route 9 is indicated by a dashed line. Each route? , 8.9, three roadside communication devices B! each use one roadside communication device 2 in common. 2 will be installed. In such a conventional route bus operation management system, transmission data such as in-vehicle display codes are sent from the route bus operation management control device 1 to on-road communications located within a short distance from the route bus 4 in consideration of the operating hours of the route bus 4. The transmitted data is transmitted to the device 2 and displayed on the in-vehicle display 6 via the in-vehicle communication device 5. This display includes internal display codes such as "Depart,""Enter," and "Refuel 1." This display allows the driver of route bus 2 to drive the route bus according to the correct driving system. .

By the way, when the in-vehicle display 2 1 of the in-vehicle display 6 is to be turned off, a lights-out command signal is transmitted from the route bus operation management control device 1 to the off-shore communication island 5. However, if the operating time of the route bus 4 is delayed, the scheduled route will be sent to the bus operation management control device l - communication B! Even if the lights-off command signal is sent to the bus 4, the road communication lI! Since the vehicle has not arrived at location 2, communication with the vehicle-mounted communication device 5 may not be possible. For this reason, since a lights-off command signal cannot be sent to the route bus 4, the in-vehicle display 6 remains lit and the display contents are not updated. Also, to precisely control the display time at the same time, each route 7, 8,
9. Second, it is necessary to install a large number of roadside communication devices 2, which inevitably makes the entire system expensive.

(Object of the Invention) In order to achieve such an object, the present invention provides an in-vehicle communication device installed in a route bus with a receiving circuit that receives transmitted data, and a time data that outputs the transmitted data to the in-vehicle display. a memory circuit in which is stored, a timer for counting the time during which transmission data is output to the in-vehicle display, and time data stored in the memory circuit set in the timer based on a display time designation signal included in the transmission data. A signal processing circuit is also included. With this configuration, according to the present invention, once the in-vehicle communication device of the route bus communicates with the bus and receives the transmitted data, a predetermined display time is counted in the timer. With this set, the display on the in-vehicle display will be manually turned off after the set time without receiving another turn-off command signal from the roadside communication device that the route bus will pass next. Moreover, according to the present invention, there is no need to add two communication devices, so the entire system can be realized at a low cost.

(Example) Hereinafter, the present invention will be explained in detail based on the example shown in FIGS. 3 to 5. This embodiment basically includes a route bus operation management control device 1, on-road communications Ps, 2, and an in-vehicle display 6 in the route bus 4, similar to the system shown in FIG. The system in the embodiment has the in-vehicle communication ff15' v
It has f-signs. That is, the in-vehicle communication device 5' of this embodiment is as follows:
Transmission of in-vehicle display hoods, etc. transmitted from the route bus operation management control device 1 via the communication line 3 to the on-road communication (Iku 2, and from the 2 communication Iso 2 via the antenna of the route bus 4) a receiving circuit 51 that receives data;
1j: A memory circuit 52 storing time data for outputting transmission data to the in-vehicle display 6, a timer 53 for counting the time during which transmission data should be output to the in-vehicle display 6, and a display included in the transmission data. A signal processing circuit 54 sets the time data stored in the storage circuit 52 in a timer based on a time designation signal, and a switch 55 turns on/off the connection between the in-vehicle display 6 and the signal processing circuits 5 and 1. including.

This in-vehicle communication device 5' controls the display time of the in-vehicle display 6 in the following manner. This control will be explained with reference to the flowchart shown in FIG. Route bus operation management control device 1
Then, data as shown in FIG. 5(a) is transmitted to the corresponding path-12 communication 1-2. The contents of this data are as shown in this figure: business office hood, vehicle number, in-vehicle display hood that gives instructions to the driver such as "stand by", "depart", "enter the garage", etc., and the display request for this in-vehicle display hood. , and its display time. The route 2 communication 8!2 communicates with the route bus 4 in operation, and if the route bus 4 is a route bus that commands an in-vehicle display, it transmits transmission data to the on-vehicle communication device 5 provided in the route bus 4. The in-vehicle communication block 5 receives transmission data with a reception circuit 51, and then processes the received transmission data with a signal processing circuit 5ll.

When the signal processing circuit 54 receives the transmission data, it determines that there is a display request and determines 'l' E S (step nl).
. Based on this determination, the signal processing circuit 54 turns on the switch 55 and further determines whether a display time is specified (step +12). If there is no designation, it is judged as No and the transmission data is given to the middle white display 6 via the switch 55. If there is a specification, it is judged as YES and the signal processing circuit 54
reads display time data based on the command signal from the memory circuit 52 and sets this display time data in the timer 53 (step n3). The timer 53 is set to display time data.

starts counting the output time of the transmitted data.
Step 115), this count output is sent to the signal processing circuit 5.
．．・Give to 1. The signal processing circuit 54 outputs the transmission data to the in-vehicle display 6 via the switch 55 while the timer 53 is providing the count output. Therefore, as shown in FIG. 5(b), one of the in-vehicle display codes 11 on the panel of the in-vehicle display 6 that corresponds to the content of the transmitted data lights up (step n4). After a certain period of time has elapsed, if the timer 53 determines that the force/fund has been increased (step 116), the signal processing circuit 54 turns off the isochi 55 again in response. As a result, the display on the in-vehicle display 6 is turned off (step 117). In this way, the display time of the transmitted data is automatically controlled by the timer 53.

If the transmitted data does not include a display time designation signal, the route bus operation management control device 1 gives a light-off command signal to the on-road communication device 2 as before.

When the signal processing circuit 54 inputs the lights-off command signal, it turns off the switch 55, so that the display is immediately turned off.
