Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an automatic control device for various devices related to operation, such as fare displays and ticket issuing machines, which operate as buses travel on regular routes. It is something.

(Conventional technology) Smooth operation of a bus requires not only the driver's safe and appropriate operation, but also the guidance and display of leading routes, routes, and stops.
This can only be achieved if fare instructions and numbered tickets are issued quickly and accurately. However, on the other hand, there has been a strong push toward one-man bus operation to save labor, and this has led to problems such as poor customer service due to driver inexperience and lack of manpower. Therefore, the development and improvement of operation-related equipment to compensate for this, as well as the automation of operation, have become important issues in public transportation management.

Therefore, for example, as disclosed in Japanese Patent Publication No. 53-40776, control signals for fare displays and ticket issuing machines are stored on magnetic tape along with stop guide signals, and the tape is set in a tape recorder. A method has been put into practical use in which a tape recorder is activated at each stop to broadcast information, and a control signal is issued at the fare change area to automatically print on the numbered ticket and change the displayed fare.

FIG. 1 is a system diagram of a conventional control system using magnetic tape. The tape recorder 2 is activated by a manual switch or a step signal from an automatic signal generator, which serves as a step signal generator 1 that emits a signal each time a stop is passed, and broadcasts guidance through a speaker (not shown), and also displays fare information. At the change area, in parallel with the broadcast, the digital fare display device 3 and the numbered ticket issuing machine 4 are operated by the control signal recorded on the magnetic tape, and the displayed fare and numbered ticket number are changed. Recording on magnetic tape is generally as shown in Figure 3-1, and the tape recorder is operated for a certain period of time in response to a step signal issued at each stop to broadcast information inside the train. When approaching a fare change zoning stop, a command signal to change the numbered ticket number is sent to the numbered ticket issuing machine during the guidance broadcast for that stop, and the number of the numbered ticket issued is increased or decreased by one. Next, after passing the fare change area stop, a display change signal for the digital fare display is sent during the announcement for the next stop, and the displayed fare is changed.

(Problem that the invention aims to solve) However, since the reproduction of signals from magnetic tape is performed in a dynamic manner by running the tape in contact with the reproduction head, noise and signal waveform distortion are likely to occur. , malfunctions of controlled equipment due to this have become a problem. Furthermore, even if a tape recorder is capable of playing back 8-track recording when it is stationary, it is forced to use 4-track recording to avoid malfunctions caused by vibrations of the bus body, and the signal recording capacity is limited. There is also the problem that it is limited to controlling digital fare displays and cannot control other one-man equipment. Furthermore, the reality is that there are other difficult problems, such as tape wear and the need for a great deal of effort to change the recorded contents in response to fare revisions.

(Means for Solving the Problems) The present invention expands the functions of semiconductor-type high-speed static memory elements that are installed in electronic digital fare display devices, which have become popular recently, and thereby In addition to controlling various related devices, the semiconductor memory is made into a cassette type that is easy to replace, dramatically increasing the amount of information storage, and eliminating the troubles associated with signal reproduction and recording updates that occur with conventional magnetic tape systems. This will wipe out all the problems.

(effect, example) The present invention will be specifically explained with reference to Examples.

FIG. 2 shows an embodiment of the present invention, in which the objects to be controlled are limited to a numbered ticket issuing machine and a digital fare display, as in the conventional case. 1 is a step signal generator similar to the conventional one. 3 is a diagram illustrating the circuit configuration of a digital fare display device by function, in which control signals for the numbered ticket issuing machine etc. are stored in a control data memory 6 made of semiconductor memory, and a display device also made of semiconductor memory. The data memory 10 stores various data necessary for fare display. 4 is a numbered ticket issuing machine similar to the conventional one. FIG. 3-2 shows an example of recording in the control data memory 6, and FIG. 3-1 shows the corresponding recording on a conventional magnetic tape.
3-4 shows an example of recording in the display data memory 10,
Figure 3-3 is a fare system table generally referred to as a triangular table.

In response to the driver's switch operation or the step signal from the automatic signal generator for each stop, the control data reading circuit 5 reads out the control data as a control signal stored in the control data memory 6 for each stop. The control data is sent to the control data discrimination circuit 7. The data is divided into control data for controlling the numbered ticket issuing machine and control data for the digital fare display in the control data discrimination circuit 7, and the former is sent to the numbered ticket issuing machine 4 via the control data conversion circuit 8, and the latter is sent to the numbered ticket issuing machine 4 via the control data conversion circuit 8. is sent to the display data reading circuit 9. The display data readout circuit 9 receives an instruction signal from the operation system controller 13, and instructs the display data memory 10 to read appropriate data in relation to this signal.
The resulting display data from the display data memory 10 is applied to the electronic digital display section 12 via the fare display section drive circuit 11 to display the fare.

For multiple operating systems, the control data and fare display data for the fare display device and numbered ticket issuing machine corresponding to each system are stored in the control data memory 6 and the display data memory 10, respectively, and operation is performed by operating the system selection operation. By specifying a system, the fare for the system may be displayed and a numbered ticket issued.

Also, control data memory 6, display data memory 1
0 to configure a memory assembly that can be attached to and detached from the fare display body using a plug-in method, or control data memory 6, control data reading circuit 5, control data discriminating circuit 7, and numbered ticket issuing machine. The control data conversion circuit 8 may be integrated and installed separately from the digital fare display.

In this invention, the fare change area data and fare display data, etc. as control signals are
- English coded as shown in Figures 2 and 4,
Since it is stored as a number and transmitted to the control system as a binary digital signal, malfunctions due to noise or counting errors can be eliminated compared to conventional simple signals such as on-off signals.

Figures 4 and 5 show other examples of the present invention, in which, in addition to the ticket issuing machine, the station name display 19, destination display 20, passenger counting device 21, etc. for each stop are to be controlled in conjunction with each other. It is. The configuration of the digital fare display as a storage unit for control data is exactly the same as that shown in FIG. 2, and the signal from the control data discrimination circuit 7 is divided by the control data distribution circuit 14 for each control object and adapted individually. I'm trying to send data.

That is, a control data memory 6 stores control data for a digital fare display, a ticket issuing machine, a destination display, a station name display, etc. in a one-man bus, and a display data memory 10 stores display data for the digital fare display. A control data reading circuit 5 reads control data from a control data memory 6 based on a signal from a stepwise signal generator 1 that generates a signal every time a stop is passed, and a control data discriminating circuit 7 reads the control data into a numbered ticket. Separate control data into ticket issuing machine, destination display, station name display, etc., and fare display control data, and use the control data distribution circuit to distribute the former control data to the ticket issuing machine, destination display, and station name display. Display data memory 1 based on the control data for the latter digital fare display device.
The fare display data is read out from 0 and the fare corresponding to the traveling position is digitally displayed.
Figure 5 shows an example of application in which existing equipment is directly incorporated into the present invention, taking into consideration actual situations, and signal converters 22 to 25 are added as necessary upstream of each control equipment. It is distinctive in that it did so.

All functional circuits of the digital fare display except for the electronic display can be compactly integrated and can be plugged into the digital fare display and made detachable.

(Effects of the invention) As explained above, in this invention, control programs for various devices that need to be controlled in a timely manner accompanying the operation of a one-man bus are recorded in a semiconductor memory, and then the control data is transmitted purely electronically. Since the system is a system for reading data manually, it is possible to eliminate malfunctions of the controlled equipment due to noise caused by the reproduction of recorded signals, which is the case with conventional magnetic tape systems, and to significantly improve reliability. In addition, due to the significant increase in the amount of information stored, it is now possible to greatly increase the number of models to be controlled, and also to store a large number of operating systems in a single control data memory and display data memory. System designation, intermediate reading, etc. can be done easily, quickly and accurately. Furthermore, when fare revisions occur, it is possible to easily respond by simply removing the semiconductor memory pack and changing the stored contents.In addition, all the problems with the conventional control method using magnetic tape for information broadcasting can be solved, and the conventional method It has the great advantage of being able to achieve various functions that have been difficult to achieve.
