Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle operation management system that is required in the transportation and passenger transport industry using trucks, buses, taxis, and the like.

[Conventional technology]

A conventional vehicle operation management system generally uses a so-called tachometer mounted on the vehicle to record engine rotational speed, travel speed, and travel distance on a time basis.

However, in this method, information such as the engine rotational speed is recorded on a recording paper on a drum that is rotated at a constant rotational speed (on this recording paper, ruled lines that serve as a time base are written in advance). Since the necessary time-varying data is mechanically recorded as time-based analog data,
Most of the data reading and processing work has to be done manually, which is extremely troublesome and takes a lot of time. Furthermore, with this conventional tachometer type, the types of data that can be recorded are limited to a very small number of types, so there is also the drawback that sufficient data necessary for operation management cannot be obtained.

Therefore, the present inventors equipped each vehicle with an electronic tachometer capable of inputting and recording various time-varying data necessary for operation management, and also installed a removable tachometer as a data recording medium. A memory cassette is used, and an electronic tachometer is used to record various time-varying data over time in the memory section of the memory cassette.Furthermore, the central control center sets the memory cassette in an automatic reading device to record the data inside the memory cassette. An electronic system that reads the data recorded on the floppy disk, edits and copies it onto a floppy disk, and then runs the floppy disk on a computer to analyze the data and create operation management materials almost automatically and completely. We are currently developing a vehicle operation management system.

FIGS. 7(a) and 7(b) schematically show the configuration of the electronic vehicle operation management system. In the same figure (a), a is an electronic tachometer located near the driver's seat (not shown) in the vehicle, and b is a memory cassette that can be detachably attached to the electronic tachometer a.
It has built-in RAM for data.

The electronic tachometer a is configured to receive detection signals from a detector (not shown) for engine speed and travel speed, which are part of time-varying data for operation management. , Dial c and pushbutton B ₁ are provided on the front panel so that the driver can manually input various time-varying data for operation management such as recording date, work content, and vehicle operation status. , b ₂ ..., etc. are provided. The electronic tachometer a has a clock circuit section (not shown) configured to output the time that is the time base for recorded data and to display the time on a time display section e provided on the front panel section. ) is built-in. Note that f ₁ and f ₂ are push buttons for setting the time for the clock circuit section. Further, the time display section e and the push buttons f ₁ and f ₂ are also used as a display section and a setting button when registering the recording date using the dial c.

The memory cassette b is attached to the electronic tachometer a by the driver at the start of the operation, and is taken out from the electronic tachometer a at the end of the operation and collected at a central control center (not shown). and,
In the central control center, as shown in FIG. 2B, a plurality of memory cassettes b (three in the illustrated example) are set in the automatic reading device g, and the various data recorded in the memory cassettes b are read. A database is created by editing and copying the data onto a floppy disk, and this database is then run on a computer (not shown) to analyze the data and create materials for operation management.

By the way, in such an electronic vehicle operation management system, the data necessary for operation management includes time-varying data and time-invariant data such as the driver code corresponding to memory cassette b. However, memory cassette b contains time-invariant data (currently only the driver code is used, but the car type, vehicle number, etc.
It is also necessary to be able to record various possible dates such as the date on which memory cassette b was taken out.

Therefore, in the conventional electronic vehicle operation management system, the driver code is input and set in the memory cassette b by the following means.

That is, as shown in FIG. 3C, a plurality of (four in the illustrated example) digital switches h ₁ , h ₂ , h ₃ , h for driver code setting are installed on the printed circuit board i in the memory cassette b. ₄ are installed in parallel, and before using memory cassette b, the central control center dismantles the outer casing of memory cassette b to expose digital switches h ₁ , h ₂ , h ₃ , and h ₄ . Set switches h ₁ , h ₂ , h ₃ , and h ₄ to predetermined values using a tool j such as a screwdriver, and write a driver code consisting of a 4-digit value (octal number) in memory cassette b. After that, memory cassette b was handed over to the appropriate driver.

[Problem to be solved by the invention]

According to the above-mentioned total electronic vehicle operation management system, compared to the previous tachometer-based system, it is possible to achieve significant streamlining of operations, and it also allows for the creation of overtime lists and daily reports for each driver. It is possible to perform detailed management tasks such as creating data and calculating salaries based on these data in an extremely short time. Furthermore, it becomes easy to reliably check unnecessary and dangerous driving conditions such as overspeeding and wavy driving, and to provide thorough guidance and management regarding safe driving to drivers.

However, even in such an electronic vehicle operation management system that has excellent effects, the following problems remain.

In other words, when inputting and setting a new driver code in a new memory cassette b, or re-entering and setting a driver code for a memory cassette b that is already in use, after disassembling memory cassette b, It is necessary to perform operations such as setting or changing numerical values for the digital switches h ₁ , h ₂ , h ₃ , h ₄ using a tool j such as the above. Also,
Other parts such as IC parts and batteries are placed close to the printed circuit board i on which the digital switches h ₁ , h ₂ , h ₃ , and h ₄ are installed, but these parts are not removed during operation with the tool j. There is also a risk of damage.
Furthermore, as is clear from the above explanation, since the driver code can be input and set using a simple tool such as a screwdriver, it is easy for the driver to commit fraud such as changing the driver code without permission. There are also problems.

The present invention was developed with the above-mentioned considerations in mind, and its purpose is to reliably and easily record time-invariant data such as driver codes without using any tools such as a screwdriver. To provide a vehicle operation management system that prevents a driver from arbitrarily changing time-invariant data even though input settings can be made.

[Means to solve the problem]

To achieve the above object, the present invention provides a vehicle operation control system comprising an electronic tachometer, a memory cassette containing a memory section, and an automatic reading device, wherein the electronic tachometer is mounted on a vehicle. On the other hand, the automatic reading device is installed in a central control center, and the memory cassette is configured to be removably attachable to either the electronic tachometer or the automatic reading device. It has a built-in non-volatile RAM for recording time-invariant data such as driver codes necessary for vehicle operation management, and an input device installed at the central control center such as the dynamic reading device for this non-volatile RAM. Only by supplying a predetermined electrical signal from
The time-invariant data can be input and set.

[Effect]

In the vehicle operation management system according to the present invention having the above-mentioned characteristic configuration, for example, in order to input and set a driver code to a memory cassette, an input device provided at a central control center or the like is used. It is only necessary to supply a predetermined electrical signal from the memory cassette to the non-volatile RAM built in the memory cassette. Therefore, time-invariant data can be input and set easily and reliably. Furthermore, since the predetermined electrical signal is input into the non-volatile RAM only by the input device provided at the central control center, such as the automatic reading device, the driver cannot freely input the time-invariant data. cannot be entered or changed, so there is no risk of fraud.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Figure 1 shows the driver's seat in a vehicle such as a truck (not shown)
The external appearance of an electronic tachometer A placed near the electronic tachometer A and a memory cassette B detachably attached to the electronic tachometer A is shown.

Memory cut B has a memory section (not shown) consisting of C-MOS RAM for recording time-varying data for operation management, and a non-volatile RAM (not shown) for recording time-invariant data for operation management. (not shown)
It has a built-in. An example of the configuration of the memory cut B is shown in FIG.

The electronic tachometer A is configured to receive detection signals from a detector (not shown) for engine speed and running speed, which are part of the time-varying data, and also receives various other time-varying data. Allows the driver to manually set variable data.
A dial 1 and push buttons 2a, 2b, 2c, 2d, etc. are provided on the front panel.

Dial 1 is a time-varying type related to specific work contents such as loading, unloading, car washing or inspection, waiting, waiting, sleeping in the car, sleeping at facilities such as inns, resting or eating, and while on board the ferry. Although it is a multi-stage switching type for setting data, it does not have time setting means for year, month, day, hour, and minute like the conventional ones. Further, the push buttons 2a to 2d are used to set time-varying data related to the vehicle operation status such as operation, empty car, actual car, return to the garage, etc., and the push buttons 2a to 2c are buttons with lamps.

3a is a registration pushbutton that is pressed when recording (inputting) the work content set by dial 1 into the memory section of memory cassette B, and 3b is a correction button that is pressed when modifying the registered content. This is the pushbutton for use. 4a-4d
5a and 5b are buzzers and lamps that issue an alarm when some abnormality occurs; 6 is a buzzer 5a and a lamp 5b;
This is a slider for setting the volume. Reference numeral 7 denotes an insertion section for removably mounting the memory cassette B, and a cover 7a which is oriented in the closing direction is provided at the entrance thereof.

By the way, as is clear from this figure, the electronic tachometer A side is not provided with a clock circuit section and its associated time display section, unlike the conventional ones, but instead, the electronic tachometer A side is not provided with a clock circuit section and a corresponding time display section. A clock circuit unit 8 is built-in to output the time that is the time base of the recorded data, and the output time by the clock circuit unit 8 is displayed at a position where it is always visible on the outer surface of the memory cassette B (in the illustrated example, on the back side). A time display section 8a is provided for this purpose. Although this time display section 8a only displays hours and minutes, the clock circuit section 8 itself displays year, month, day, hour, minute,
It is designed to be able to measure and output time down to the second.

FIG. 2 shows an automatic reading device C set up in a central control center (not shown). This automatic reading device C has a function of automatically reading various operation management data recorded in each memory cassette B when a plurality of memory cassettes B are set, and editing and copying the data onto, for example, a floppy disk. , has a function of setting the time to the clock circuit section 8 in the memory cassette B, and a function as a so-called input device for inputting and setting predetermined time-invariant data to the nonvolatile RAM.

That is, the automatic reading device C reads the time (year, month,
It has a built-in reference clock circuit section 9 that measures (day, hour, minute, second) and outputs it as an electrical signal. and,
The front panel section is provided with a time display section 9a for displaying the output time from the reference clock circuit section 9, as well as an up push button 10a and a down push button 10a for setting the time of the reference clock circuit section 9 itself. A push button 10b and push buttons 11a to 11e for setting items are provided.

Reference numeral 12 denotes a set push button which is pressed when setting the time of the clock circuit section 8 on the side of the memory cassette B, and is provided on the front panel section. When performing this time adjustment, an electrical signal related to the output time is supplied from the reference clock circuit section 9 to the clock circuit section 8 side.

Further, the front panel section includes numerical buttons 13a to 13h for inputting and setting time-invariant data such as a driver code consisting of a four-digit numerical value to the nonvolatile RAM in the memory cassette B, and the input buttons 13a to 13h. A set push button 14 is provided which is pressed during setting.

The time display section 9a normally displays hours and minutes, but when the item setting pushbuttons 11a to 11e are pressed to set the time, the time display section 9a displays the year, month, day, hour, minute, and second. Furthermore, when numerical buttons 13a to 13h are pressed to input and set time-invariant data, the numerical values are displayed.

In FIG. 2, reference numeral 15 is an eject lever for removing the memory cassette B from the automatic reading device C.

Figure 3 shows nonvolatile RAM in memory cassette B.
16 shows a signal flow when time-invariant type data is input and set to No. 16. This input setting can be used to newly set time-invariant data such as driver code in a new memory cassette B.
This is done when changing the time-invariant type data set in the memory cassette B that is already in use.

That is, the setting is performed by loading the memory cassette B into an automatic reading device C provided at the central control center, and then pressing the numerical buttons 13a to 13h and the pushbutton 14 for setting. In this case, in the automatic reading device C, a code setting section 17 consisting of numeric buttons 13a to 13h and a pushbutton 14 for setting sends a predetermined message regarding time-invariant data to the time display section 9a and data output section 18. An electrical signal is sent. The electrical signal sent from the data output section 18 to the input/output interface section 19 of the memory cassette B is input into the nonvolatile RAM 16 and stored therein. This nonvolatile RAM 16 can read and write data by sending electrical signals from the outside, and does not require electric power to hold data.

Irrespective of this, electrical signals relating to hours and minutes are sent from the clock circuit section 8 to the clock display section 8a.

In addition, in Fig. 3, 20 is C-MOS・
A memory section for recording time-invariant data consisting of RAM; 21 is a clock circuit section 8; a time display section 8;
a, input/output interface section 19, memory section section 2
This is a backup power supply for 0, etc.

FIG. 4 shows the flow of signals when time adjustment is being made to the clock circuit section 8 in the memory cassette B. This time setting is performed by the driver at the central control center before starting operation by loading the memory cassette B into the automatic reading device C and pressing the setting pushbutton 12.

In this case, in the automatic reading device C, electric signals related to hours and minutes are sent from the reference clock circuit section 9 to the time display section 9a, and electrical signals related to the hours and minutes are sent to the data output section 18. An electrical signal is sent. Then, electrical signals relating to the year, month, day, hour, minute, and second sent from the data output section 18 to the input/output interface section 19 of the memory cassette B are inputted to the clock circuit section 8 to adjust the predetermined time. It will be done. Electric signals relating to hours and minutes are sent from the clock circuit section 8 to the time display section 8a. Therefore, by comparing the displayed times on the time display section 8a on the memory cassette B side and the time display section 9a on the automatic reading device C side, it is possible to confirm whether or not the desired time setting has been performed correctly. .

Figure 5 shows memory cassette B when the vehicle is in operation.
This figure shows the flow of signals when recording various types of time-varying data on a computer. This time-varying data is recorded with the driver attaching the memory cassette B to the electronic tachometer A at the start of the operation.

In this case, when the operation management data input to the data output section 22 in the electronic tachometer A is sent to the input/output interface section 19 of the memory cassette B, this input/output interface section 19 receives the data. At the same time as transmitting the data to the memory section 20, a trigger signal is sent to the clock circuit section 8 to record the time (year, month,
day, hour, minute, second) are input into the memory section 20.
In this way, the time and operation management data are recorded in the memory section 20. Incidentally, electrical signals relating to minutes are always sent to the time display section 8a at regular intervals regardless of the trigger signal.

Figure 6 shows the signal when the automatic reading device C reads the data recorded in the memory cassettes B collected at the central control center after the vehicle has returned from the warehouse after the completion of the operation. It shows the flow.

In this case, the nonvolatile memory in memory cassette B
Various operation management data such as time-invariant data and time-varying data sent from the RAM 16 and memory unit 20 via the input/output interface unit 19, and time data corresponding to the time-varying data are as follows: Data input section 23 of automatic reading device C
The data is then input from the data input section 23 to the data editing/copying section 24, where it is created as a database on a floppy disk.

In the above-described embodiment, the time display section 8a output from the clock circuit section 8 built into the memory cassette B was provided in the memory cassette B itself, but this time display section 8a was provided in the electronic tachometer A. It may also be provided on the side.

Further, in the above-mentioned embodiment, the automatic reading device C itself has a reference clock circuit section 9 built therein for setting the time to the clock circuit section 8 built in the memory cassette B, but instead of this, A reference clock separate from the automatic reading device C is used as the automatic reading device C.
Alternatively, a reference clock turning device (completely separate from the automatic reading device) exclusively for time setting having a reference clock circuit section may be used.

〔Effect of the invention〕

As explained above, in the present invention, a memory cassette that records time-varying data over time is provided with a non-volatile memory cassette for recording time-invariant data such as driver codes necessary for vehicle operation management.
Built-in RAM, and for this non-volatile RAM,
The time-invariant data can be input and set to the non-volatile RAM only by supplying a predetermined electrical signal from the input device installed in the central control center, such as the automatic reading device. When inputting and setting unchangeable data into a memory cassette, it is no longer necessary to disassemble the memory cassette or use tools to set (change) numerical values on multiple digital switches. Instead, a simple operation such as setting the memory cassette into an input device provided at a central management center or the like and operating a predetermined button is sufficient.

In addition, since the time-invariant data input settings for the memory cassette are performed only by input devices installed only at specific locations, there is a risk that unauthorized settings or changes may be made by the driver. It disappears.

In addition, the non-volatile memory built into the memory cassette
RAM has a larger storage capacity than traditional digital switches, and therefore
By using RAM, it is possible to input and set not only the driver code but also various time-invariant data necessary for vehicle operation management, such as vehicle type, vehicle number, and date of removal of memory cassette b.
It is possible to perform even more precise vehicle operation management.
