Description

[Detailed Description of the Invention] The present invention is a bus operation management device that communicates between buses and stops, and in particular displays a half-way light and the scheduled time of the next bus on the bus stop side, and displays the scheduled time of the next bus on the bus side. The error time is displayed.

Many applications have been made for bus guide devices that receive signals from buses and display the scheduled time of the next bus at the bus stop. The present inventor also previously filed an application for ``Bus Operation Guide Device'' with a filing date of May 24, 1988. However, there was no way for the bus driver to communicate with the bus stop to properly indicate whether the bus was ahead or behind schedule.

The present invention has been made in view of the above-mentioned current situation, and the bus side sends an identification signal (wireless signal) that differs depending on the destination to the stop, and the bus stop side receives the identification signal,
The system calculates the difference from the scheduled time and sends it to the bus side as an error signal, and also displays the next scheduled time for each destination.First, the bus side receives the error signal and displays it as an error time on the display device. be.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 4 shows a block diagram of the device on the bus side, and FIG. 5 shows a block diagram of the device on the bus stop side. As shown in Fig. 1, when the bus (3) approaches a stop, the driver turns on the device according to the present invention, and the device starts operating, transmitting different radio waves for each destination through the oscillating device (5) and transmitting device (4). Emit a radio signal.

Radio signals are constructed from a combination of multiple frequencies to prevent malfunctions caused by interfering radio waves and urban noise, and are emitted as radio waves by modulating a predetermined carrier wave. The radio waves were so weak that the bus stop would detect them only when the bus approached the stop. Further, infrared rays from a light emitting diode may be used instead of radio waves. Switch off the radio waves
Continue emitting until

At the stop (1), the radio wave is received by a receiving device (8) and demodulated. The scheduled bus time shown in FIG. 3 is stored in the memory (6). In this case, row A and row B.

There are six lines of buses divided into three destinations, and scheduled times for each are stored in correspondence with address numbers. The station consists of a receiving device (8), a CPU (7), a counter (1 busy, display device ++4), a timekeeping section (131, a memory (6), an oscillator (51, a transmitting device) device (4).

The flow of signals within a bus stop will be explained with reference to the flowchart shown in FIG. First, if the station (which received the radio waves emitted from the station side and read the signal by demodulating it and issued the radio signal) is the first station, the power of the display device is turned on. In order to save electricity when bus services are suspended at night, the power to the display device is turned off when the last bus passes.
This is to keep it. In this case, the last bus is A
Since the address number 20 in the line is PMlo:oo, when the corresponding bus passes by at this time, the power of the display device is turned off, and at that time, a judgment is made to return the counter 01 to 0. Note that the main power source is always turned on, but since the power consumption in this case is smaller than the power consumption of the display device 04), there is no problem in saving power. When a wireless signal is received while the counter is at 0, it means that the bus is starting, and the power to the display device is turned on. Next, the schedule timetable information in the memory (6) corresponding to the current address of the counter circle provided for each destination is read,
Next, let X be the scheduled time of the bus that was read, and read the time when the radio signal indicating that the bus is busy is received from the clock section α3) Y
Let (X-Y) be Z, which is the error time from the scheduled time of the corresponding Similar to the radio waves from the bus side, the radio waves at this time are weak to avoid affecting other buses and are only received by buses that are close to the bus stop. A certain counter O11 adds N+1) to the current counter number N, and displays the next scheduled time. In this way, each counter address is incremented by 1 each time a bus passes, and the scheduled time corresponding to the counter number is read and displayed. In this example, line A is the slowest and last bus, so when the number of the counter corresponding to line A becomes (N+1) from N, which is the address of the last bus on line A, the power of display device 04J is turned off. be done.

Next, on the bus side, the radio waves from the stop are received and demodulated by the receiving device (8), and the error time is displayed on the bus side display device (10). As shown in the flowchart of FIG. 7, the message END is displayed when it is the last stop.

Next, when implementing the present invention, operating means in the case where a scheduled bus service is suspended will be explained. Down switch (121
As shown in Figure 8, is divided into multiple switch groups and connected to CP [J In response to the suspension of service of the two cars, the driver turns on switch 2, which is the second one from the right, at the time of departure. The weight data L L I-1i, that is, 0010, is input to the CPU.The weight data is transmitted to the transmitting device (4
) to the bus stop.

On the bus stop side, as shown in the flowchart in Figure 9, normally when a signal is received from the bus, a counter corresponding to each destination is added to the current N as N+1→N, but the weight code is read and the weight is If the data is L,
The weight data is added to the counter as N+1+L→N, and the primary scheduled time is displayed as the intended scheduled time.

Since the present invention is as described above, it produces the following effects.

In other words, by accurately displaying the scheduled time on the bus stop side, people waiting for a bus can avoid the inconvenience of having to wait for a bus that has already left. In addition, by displaying the time difference from the scheduled time on the node side, the driver can quickly control the operation.
