DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle information collecting apparatus suitable for collecting vehicle information indicating the operation state of a vehicle, and more particularly to vehicle information for collecting various event data input by key operation. It relates to a collection device.

[0002]

2. Description of the Related Art Conventionally, for example, in a bus company or the like, in order to manage the operating state of a bus owned by the company, in addition to a running speed and a running distance of a bus vehicle that change every moment, for example, a bus vehicle that changes in a time series State data of each part such as door opening and closing, and input by key operation, such as charter, ride,
Various event data such as crew codes, workplace codes, and system codes are collected.

[0003] In particular, event data is collected by sequentially writing the event data to an internal storage device such as an internal RAM and a portable storage medium such as an IC card memory at the time of occurrence, and based on the collected vehicle information. The operating state of the bus vehicle is analyzed by using this method.

Incidentally, since event data is input by manual key operation, erroneous data may be input due to an operation error. Therefore, the data input by the key operation is once displayed on the display, and the display is used to confirm that the input is correct before performing the actual writing operation.

[0005]

However, if there is a misconception at the time of confirmation, erroneously input data may be written as it is, and once written data cannot be corrected. This means that although the contents of the internal storage device to which the data is written can be accessed at the time of the data generation, the contents of the portable storage medium cannot be directly accessed, and the contents that are ultimately subjected to analysis are not accessible. This is because the contents cannot be corrected.

Therefore, conventionally, when an error is known, a troublesome operation of notifying the operator of the fact in advance by reading the contents of the portable storage medium and informing the operator of a rear analyzer for correction and having the operator correct the error is performed. Was needed.

Accordingly, in view of the above-mentioned conventional problems, the present invention corrects even data that has been created by an input error due to a key operation, and has been once determined and written, when the input error is noticed. It is an object of the present invention to provide a vehicle information collecting device capable of collecting correct data by performing an input operation for correcting the vehicle.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a view showing one embodiment of a vehicle information collecting apparatus according to the present invention. In FIG. 2, reference numeral 1 denotes a control box, which operates according to a predetermined control program stored in a ROM (not shown). CPU that performs tasks such as display control, data transfer, and data processing
11 and an internal RAM 12 as an internal storage device in which various data including vehicle operation information is written.

First, a handy terminal 2 having a display 21 and a keyboard 22 is connected to the control box 1. Display 21 is LCD, VFT, L
It is composed of a display element such as an ED and displays various information such as a time and a message. The keyboard 22 is used as an input unit for inputting various data described later, and includes a numeric keypad, function keys, and the like.

Further, an IC memory card reader / writer (R / W) 3 is connected to the control box 1, and the IC memory card reader / writer (R / W) 3
An IC memory card 31 as a portable recording medium is removably mounted in. The control box 1 is further connected with a travel sensor 4, a rotation sensor 5, a door open / close detection switch 6, and the like. The travel sensor 4 generates a pulse every time the vehicle travels a predetermined distance, and the rotation sensor 5 detects the rotation of the engine of the vehicle.

The data collected by the apparatus having the above-described configuration includes data such as speed, engine speed, and mileage, as well as events such as charter, ride, crew code, workplace code, system code, etc., which are input through the keyboard 22. Data. When the event data is input from the keyboard 22, the control box 1 sequentially writes the data into a predetermined area of the internal RAM 12 and the IC memory card 31.

The control box 1 reads signals from the travel sensor 4 and the rotation sensor 5 every second, for example, based on the accumulated values of the data such as the speed, the engine speed, and the travel distance. Internal RAM 12 and IC
These are sequentially written to the memory card 31. In particular, data on speed and mileage are obtained from the travel sensor 4
The count value obtained by counting pulses from
Obtained by reading every 5 seconds and converting to speed,
The data is sequentially written to a predetermined area of the internal RAM 12 and written to the IC memory card 31 at a certain timing.

The IC memory card 31 on which predetermined data is written is taken out from the IC memory card R / W3,
The data is analyzed by a computer in an office (not shown).

The keyboard 22 of the handy terminal 2 is provided with various function keys in addition to the numeric keypad.
“Cancel”, “Correction”, “SET”, “Write”, “Charter”, “Sharing”, “Crew Code”, “Work Code”,
“System code”, “spare”, etc. are provided, and the function of each key will be described later. In the internal RAM 12, a writing area for writing 100 event data from 00 to 99 is prepared in advance.

In the above configuration, the IC memory card R
When the IC memory card 31 is inserted into / W3, the contents are checked, and then a predetermined process when the bus vehicle leaves the garage, that is, a retrieval data creation process is performed.
Then, the speed, the traveling distance, and the state of each part which change with the operation of the bus vehicle are monitored, and these data are sequentially stored in the internal R.
The data is sequentially written to the AM 12 and the IC memory card 31.

When the "charter", "sharing", "crew code", "workplace code", "system code", and "spare" keys are operated, and if necessary, the ten keys are further operated, so that event data can be obtained. The event data input and input by the key operation is displayed on the display 21 of the handy terminal 2. By checking this display, it is checked whether the input event is correct. If the event is correct, the “SET” key is operated, and the event data input by the key operation is stored in the internal RAM 12 and the IC memory card 3.
Written to 1.

If it is not correct by the above confirmation, the input contents can be corrected by operating the "correction" key. Further, when it is desired to cancel the data input by the key operation, the original state can be restored by operating the "cancel" key.

When the user notices an error in the event data once written in the internal RAM 12 and the IC memory card 31, or when he or she doubts whether the written event data is correct, the "call" key is operated. By operating the key corresponding to the content of the event data to be called and confirmed, the already written event data is displayed on the display 21. When it is desired to correct this, the operation of the numeric keypad is followed by the operation of the numeric keypad.
By operating the "T" key, the data is stored in the internal R
It is written to AM12. Then, a corrected flag prepared in a predetermined area of the internal RAM 12 is turned on to indicate that the event data has been corrected.

When the bus vehicle has been operated for one day or one time, the "SET" key is operated following the "Write" key operation, thereby performing the warehousing process. Then, when there is no ON flag in the corrected flag, data in the internal RAM 12 that has not yet been written to the IC memory card 31 is written to the IC memory card 31, and a series of operations ends. On the other hand, if any of the corrected flags is on, the internal R
A so-called overwrite is performed, in which all the data from the exit from the AM 12 to the entry in the AM 12 is written on the already written data in the IC memory card 31, and a series of operations is completed.

The details of the data collection operation briefly described above will be described below with reference to the flowcharts of FIGS. 3 to 5 showing the work performed by the CPU 11 in the control box 1. The CPU 11 starts the operation when the power is turned on, and checks in the first step S1 whether the IC memory card 31 is mounted on the IC memory card R / W3.

If the IC memory card 31 is set and the determination in step S2 is YES,
After checking the C memory card, the process proceeds to step S3 to create predetermined exit data of the bus vehicle. Then, the process proceeds to step S4 to perform an input / write process of event data, and then to a step S5, performs an input / write process of other data. Note that key input processing and external input processing of the handy terminal 2 are performed by interruption when they occur.

The input / write processing of the event data in step S4 is specifically performed as shown in the flowcharts of FIGS. First, in step S41, it is determined whether or not the "call" key has been operated. If the determination in step S41 is NO, the process proceeds to step S42 to determine whether or not the "write" key has been operated. If the determination in step S42 is NO, the process proceeds to step S5 via another step (not shown).

When correcting the event data written in another step (not shown) of the event data input / write processing in step S4, the "call" key is first operated, and this operation causes the determination in step S41 to be Y.
When it becomes ES, the process proceeds to step S43. In step S43, the display “Yobidashi & Kakunin” is displayed on the display 2.
Let 1 do it. Thereafter, the flow advances to step S44 to determine whether or not the "workplace code" key has been operated. If the determination in step S45 is YES, the flow advances to step S46 to determine whether there is existing input data. If the determination in step S46 is NO, the process proceeds to step S5 via a step not shown.

If the determination in step S46 is YES, that is, if there is existing input data, the input data is displayed, for example, as "01 SHOKUBA 12345". Subsequently, the process proceeds to step S47, where it is determined whether or not the numeric keypad has been operated. If the determination in step S47 is NO, the process proceeds to step S48 to determine whether or not the "release" key has been operated. If the determination in step S48 is also NO, the process proceeds to step S49, where "S
It is determined whether the "ET" key has been operated. When the determination in step S49 is NO, the process returns to step S47, and these steps are repeated until any of steps S47 to S49 becomes YES.

When the determination in step S47 is YES, that is, when the numeric key is operated, the flow advances to step S50 to display the input by the numeric key on the display 22. Thereafter, the process proceeds to step S51 to determine whether or not the "correction" key has been operated.
If O, the process proceeds to step S52 to determine whether or not the "SET" key has been operated. If the determination in step S52 is NO, the process returns to step S50 and returns to step S50.
These steps are repeated until the determination of either 51 or S52 becomes YES.

When the determination in step S51 is YES, that is, when the "correction" key is operated, the flow returns to step S46 to return the display on the display 21 to the original state. Also,
If the determination in step S52 is YES, that is, "S
If the "ET" key has been operated, the flow advances to step S53 to turn on the correction flag. In the next step S54, data is written to the internal RAM 12, and the subsequent step S55
In, the display on the display 21 is returned to the normal display, and the process proceeds to the next step S5.

When the determination in step S48 is YES, that is, when the "cancel" key is operated, the flow returns to step S41. When the determination in step S49 is YES, that is, when the “SET” key is operated, the process proceeds to step S56, where the data input by the key is confirmed, and a new data code is attached to the data. After the display of “02 SHOKUBA 12346” is performed, the process proceeds to step S5.

When step S44 is NO, the process proceeds to a step (not shown) to determine the presence or absence of an operation such as a "ride",... "Reserve" key. When an operation is performed, the same processing as in steps S45 to S56 is performed. Do. And
If the determination at the step not shown is NO, the process proceeds to step S57 to determine whether the "charter" key has been operated. If the determination at step S57 is NO, the process proceeds to step S58 and the "cancel" key is pressed. It is determined whether or not the operation has been performed. If the determination in step S58 is NO, the process returns to step S44 to wait for operation of any of the keys. If the determination is YES, the process returns to step S41 to perform normal event data input processing.

If the determination in step S42 is YES, that is, if the "write" key has been operated, the flow proceeds to step S59, in which the display "OPERATION SET" is displayed, and then the flow proceeds to step S60 to proceed to step S60. It is determined whether the "correction" key has been operated. If the determination in step S60 is NO, the process proceeds to step S61 to determine whether the "SET" key has been operated. If the determination in step S61 is NO, The process returns to step S60 and waits for any step to become YES. When the determination in step S60 is YES, that is,
If the "correction" key has been operated, the flow proceeds to step S62 to return the display of the display 21 to the normal display, and then returns to step S42.

When the determination in step S61 is YES, that is, when the "SET" key is operated, the flow advances to step S63 to perform a predetermined warehousing process, and then to step S64. In step S64, it is determined whether or not there is the corrected flag turned on in step S53, and if this determination is NO, step S6
Proceeding to 5, the data remaining in the internal RAM 12 is written to the IC memory card 31. Then, if the writing is normal, in the subsequent step S66, “OPERATION
After "K" is displayed, the IC memory card 31 is ejected in a step (not shown), and a series of operations is completed. The processing when the writing is NG is omitted.

If the determination in step S64 is YES, that is, if the corrected flag is on, the flow advances to step S67 to cause the display 21 to display "OPERATION", and then to step S68. All the data of the internal RAM 12 from exit to entry is written to the IC memory card 31. If the writing is normal, the display 21 displays "OK" in the following step S69, and then the IC memory card 31 is ejected in a step (not shown) to end a series of operations. The processing when the writing is NG is omitted.

As is clear from the above description of the flowchart, the CPU 11 sequentially calls the event data already written in the internal RAM 12 by executing steps S41 to S55, corrects the called event data, and corrects the event data. Functions as a correcting means 11a for turning on a corrected flag indicating that the corrected data has been corrected, and by executing steps S42 to S69, when the corrected flag is turned on at the end of the vehicle operation, all of the event data in the internal RAM 12 is converted to an IC. It functions as a writing means 11b for writing to the memory card 31 for rewriting.
