[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for collecting operation information of a commercial vehicle, such as a taxi vehicle or a companion vehicle of a driving agency, for collecting operation information of the commercial vehicle. The present invention relates to a method and an apparatus for generating frame data used when converting various states of a sales vehicle such as an agency charge into cumulative index data for transmission, and a method and an apparatus for collecting operation information of the sales vehicle based on the frame data.

[0002]

2. Description of the Related Art Conventionally, in a taxi vehicle, generally, taxi meters are used to count, accumulate, and accumulate data that changes with the taxi driving, time, etc. The data is output as system data, and the operation information collecting device connected to the taxi meter collects the system data from the taxi meter and records it in a portable storage medium such as an IC memory card. The operation of the operation information collection device described above is performed according to the setting data read from the system card loaded in the operation information collection device, and the crew member data determined by the operation information collection device is recorded in the storage medium together with the system data. It

Then, the storage medium is taken out from the operation information collecting device when the taxi returns to the business office, loaded into a host computer for labor management of the business office, and read from the storage medium in the host computer. A daily work report for each crew member is created based on the system data.

By the way, in recent years, in accordance with the fact that the items of the accumulated data to be referred to when creating the daily work report are different for each user or the contents of labor management are enhanced, the accumulated data is accumulated. Taximeters have emerged that output system data with an increased amount of data by increasing the number of items and adding unprecedented data other than cumulative data.

[0005] In recent years, with the aim of improving services in terms of passenger fees and activating competition with other companies in the same industry,
The new fare system such as discounts has begun to be implemented, and the boarding fare that applies this new fare system is calculated by the external fare calculation device that receives the above system data from the taxi meter in order to eliminate the need to modify the taxi meter. Calculated and displayed independently. Therefore, when using such an external fare calculation device, data such as the cumulative index of the boarding fare after discount newly generated due to the application of the new fare system is added to the contents of the system data from the taxi meter. In addition, system data having a larger data amount than that from the taxi meter is output from the external charge calculation device, and this is collected by the operation information collection device.

Then, like the taximeter, the appearance of an external charge calculation device that increases the number of items of cumulative data added by the external charge calculation device or outputs system data in which data other than the cumulative data is increased is Of course, it is a request.

Therefore, when viewed from the operation information collection device side, system data whose data amount, in other words, data length is unknown, is received from the taximeter or the external charge calculation device.

However, if the data length of the system data received from the taxi meter or the external charge calculation device remains unknown, the operation information collection device recognizes that the received data has excess or deficiency and normalizes the system data. Even though it is being received, it is determined that the reception is abnormal.

Therefore, for example, the data for specifying the data length is recorded in the system card, and when the operation information collecting device reads various setting data from the system card, the data for specifying the data length is read together. Based on this, it is considered that the data length of the system data to be collected is recognized in advance so that the system data from the taximeter or the external charge calculation device can be normally collected. As specific contents of the data length specifying data, data such as the model of the taxi meter or the external charge calculation device that can specify the data length of the system data output by the taxi meter or the external charge calculation device,
There is data indicating whether the connection target is a taxi meter or an external charge calculation device, or data indicating the data length itself of the system data output by the taxi meter or the external charge calculation device.

[0010]

However, in the method of reading the data length specifying data from the system card of the operation information collecting device described above, if the data length of the system data to be collected changes due to the change of the connection target, etc. At the same time, it is necessary to rewrite the data for specifying the data length of the system card, which is troublesome. And this problem is not limited to the case of collecting system data output by a charge calculation meter installed in a taxi vehicle, such as a taxi meter or an external charge display device, and a driving agent installs it in an accompanying vehicle to drive. This also occurs when collecting the system data output by the charge calculation meter used to calculate the substitute charge.

The present invention has been made in view of the above circumstances, and a first object of the present invention is to operate a charge calculation meter mounted on a business vehicle such as a taxi vehicle or a companion vehicle of a driving agency, from the charge calculation meter. A device that collects vehicle operation information,
When transmitting frame data that is converted into cumulative index data of various states of business vehicles such as boarding fee and driving agency fee, the collection side does not judge as abnormal even if the data length of the frame data is different, and it is judged as normal It is an object of the present invention to provide a business vehicle operation information collection frame data generation method and a business vehicle operation information collection frame data generation apparatus suitable for use in implementing this method.

A second object of the present invention is to provide an operation information collecting method for a commercial vehicle, which can collect normally even if the data lengths of the frame data to be collected are different, without judging it as abnormal. It is to provide a business vehicle operation information collection device suitable for carrying out the method.

According to the business vehicle operation information collection frame data generating method of the present invention as set forth in claim 4, a predetermined value constituting the additional detection data in addition to the basic error detection data is set to the basic cumulative index. By setting the value of the number of bits that exceeds the number of bits of each character that is the data format of the data group, for example, the basic error detection data is added to the data content of the same bit position of each character of the basic cumulative exponential data group. However, in the case of BCC (block check character) for obtaining the parity of each bit portion, the predetermined value has a larger number of digits than the value as the basic error detection data.

Therefore, among the values of the additional detection data obtained by adding the predetermined value to the basic error detection data, it is possible to confirm whether or not the collected system data is the combined system data by the value of the upper digit. Not only is it possible
The value of the basic error detection data before addition is easily recognized by the value of the lower digit, and if the collected system data is synthetic system data by using this, the basic cumulative index of the synthetic system data. It is possible to confirm whether or not there is an error in the content of the data at the same time as confirming whether the collected system data is basic system data or synthetic system data. The same applies to the commercial vehicle operation information collection frame data generation device of the present invention described in claim 8.

The frame data to be collected is confirmed by checking whether the data of the frame position corresponding to the acquired frame position corresponds to the contents of the basic cumulative index data group or the additional detection data. Whether or not it is, or whether it is synthetic frame data, even if it is not known in advance, as long as it is these basic frame data and synthetic frame data, the collected frame data will not be misjudged as abnormal data. It is possible to collect it reliably.
Note that this is the same as in the operation information collection device for a commercial vehicle according to the thirteenth aspect of the present invention.

Further, according to the business vehicle operation information collection method of the present invention as set forth in claim 10, the combined error detection data which plays the same role as the basic error detection data in the basic frame data is the combined frame data. Since it is placed after the additional cumulative index data group, when this composite system data was collected, it was placed at the frame location of the composite frame data that corresponds to the frame location where the basic error detection data of the basic frame data is placed. Even if the data is not the combined error detection data for detecting the received content error of the combined frame data but the additional detection data, the basic frame data is checked to see whether the combined frame data is error-free. It will be possible to confirm as if it was collected. It should be noted that this is claimed in claim 14.
The same applies to the operation information collection device for a commercial vehicle of the present invention described in 1.

Furthermore, according to the operation information collection method for a commercial vehicle of the present invention as set forth in claim 11, the data of the frame portion after the basic cumulative index data group in the collected system data is the additional detection data. As a result, when it is determined that the system data is composite frame data,
By subtracting a predetermined value from the data at the frame location after the basic cumulative index data group that is the additional detection data, and confirming whether the data after the subtraction corresponds to the contents of the basic cumulative index data group, It is also possible to confirm whether or not there is an error in the content of the basic cumulative index data in the collected composite frame data. Note that this also applies to the business vehicle operation information collection device of the present invention according to claim 15.

Further, according to the operation information collecting method for a commercial vehicle of the present invention as set forth in claim 12, the predetermined value forming the additional detection data in addition to the basic error detection data is the basic cumulative index data group. Since the value of the number of bits exceeds the number of bits of each character that is the data format,
For example, in the basic error detection data, the data contents of the same bit portions of each character of the basic cumulative exponent data group are added to obtain the parity of the bit portions BC
In the case of C (block check character), the predetermined value has a larger number of digits than the value as the basic error detection data.

Therefore, it is possible to confirm whether or not the collected system data is the combined system data by the value of the upper digit of the value of the additional detection data obtained by adding the predetermined value to the basic error detection data. Not only is it possible, but the value of the lower digit makes it easy to recognize the value as the basic error detection data before addition, and using this, if the collected system data is combined system data, It is possible to confirm whether or not there is an error in the content of the basic cumulative index data in the system data at the same time as checking whether the collected system data is the basic system data or the synthetic system data. Note that this is the same as in the operation information collection device for a commercial vehicle according to the sixteenth aspect of the present invention.

Next, the operation (action) of the taximeter system of the present embodiment having the above-mentioned configuration will be described.

First, when the tariff status of the taximeter main body 1 shifts from the commercial tariff status to the empty tariff status due to the operation of the empty car tariff button 105, the system data transmission line 125 from the taxi meter main body 1 is correspondingly changed. If the setting switch 121 of the taxi meter main body 1 is set to the first system data via the operation information collecting device 5, the first system data having the content shown in FIG. If the second system data is set, the second system data having the content shown in FIG. 6 is output.

Also, when a system data output request signal is input from the operation information collection device 5 via the system data transmission line 125, the first and second output signals are also processed in the same manner as described above in accordance with this. The system data corresponding to the setting state of the setting switch 121 is output from the system data.

When the system data from the taximeter main body 1 is input through the system data transmission line 125, the operation information collecting device 5 counts 1 from the beginning.
The value of the 12th data counted from the beginning is added to the value obtained by adding the data up to the 1st bit for each bit, and it is determined whether the added value for each bit is an odd number (or even number). That is, the block check of the data from the header of the input system data to the item number 10 is performed.

If all the added values for each bit are odd (or even) by this block check, the input system data is determined to be the first system data having no error in the contents. Then, the system data is taken in as the first system data, the data card writer 515 writes and records the first system data in the data memory card 7, and other necessary processing is performed.

On the other hand, if at least one of the added values for each bit does not become an odd number (or even number) by the block check of the data from the header of the input system data to the item number 10, from the beginning The value obtained by subtracting "10H" from the value of the 12th data counted is added to the value obtained by adding the 11th data counted from the beginning for each bit, and the added value for each bit is all odd ( Or a even number), the block check of the data from the header of the input system data to the item number 10 is performed in the same manner as described above.

By this block check, if at least one of the added values for each bit does not become an odd number (or even number), the input system data becomes the first
And the second system data, it is determined that there is an error in the data from the header to the item number 10, and the input data is not captured,
Instead, a system data output request signal is output to the taximeter main body 1 via the system data transmission line 125.

Further, by performing a block check of the data from the header to the item number 10 by the value obtained by subtracting "10H" from the value of the 12th data counted from the beginning, all the added values for each bit are odd (or even). ), It is determined that the input system data is the second system data and there is no error in the data from the header to the item number 10.

Then, following this, 1 from the beginning
Whether the value of the 18th data counting from the beginning is added to the value obtained by adding the 3rd to 17th data for each bit, and whether the added value for each bit is all odd (or even) A block check of the data from the item number 12 to the item number 16 of the input system data is performed to determine whether or not it is determined.

If all the added values for each bit are odd (or even) by this block check, first, the second system data in which there is no error in the data from the header to the item number 10 is used. Of the input system data determined to be present, it is determined that there is no error in the data from item number 12 to item number 16 excluding BCC1 of item number 11 and BCC2 of item number 17, and this The system data is taken in as second system data, and the data card writer 515 writes and records the second system data in the data memory card 7, and performs other necessary processing.

On the other hand, when at least one of the added values for each bit is not an odd number (or an even number) by the block check of the data of the item number 12 to the item number 16 from the header of the input system data, Is
The BCC1 of the item number 11 and the BCC2 of the item number 17 are excluded from the input system data, which has been determined to be the second system data having no error in the data from the header to the item number 10. , It is determined that there is an error in the data from item number 12 to item number 16,
The input data is not captured, and instead, a system data output request signal is output to the taxi meter main body 1 via the system data transmission line 125.

As described above, according to the taximeter system of the first embodiment, in the taximeter main body 1, the item numbers 1 to 1 are set according to the setting state of the setting switch 121.
Two types of system data, first system data including cumulative index data of 0 and second system data including cumulative index data of item numbers 12 to 16 in addition to the cumulative index data of item numbers 1 to 10. In outputting either one of the above, in the frame position of the item number 11 in which the BCC functioning as the block check data is arranged in the first system data, in the second system data, the above-mentioned item number 12 to The configuration is such that the data obtained by adding the value of “10H” indicating that 16 cumulative index data continues to the value of BCC is arranged.

Further, according to the taxi meter system of the first embodiment, in accordance with the configuration of the taxi meter body 1 described above, the item number 11 of the system data input from the taxi meter body 1 in the operation information collecting device 5 is used.
The block check is performed by adding the value of the data arranged at the frame location of the header to the value obtained by adding each data arranged at the frame location of the header and item numbers 1 to 10 for each bit, and the result is OK. In this case, the input system data is determined to be the first system data having no error in the data.

If the result of the above block check is not OK, the header and item numbers 1 to 1 are further added.
It is recommended that the cumulative index data of item numbers 12 to 16 described above be continued from the value of the data placed in the frame place of item number 11 to the value obtained by adding each data placed in 10 frame places for each bit. A block check is performed by adding a value obtained by subtracting the value of "10H" shown, and the result is O
If it is not K, regardless of whether the input system data is the first system data or the second system data, it is determined that there is an error in the data from the header to the item number 10, and the result is OK. Is configured to determine that the input system data is the second system data having no error in the data of item numbers 1 to 10.

Moreover, if the result of the block check by the value obtained by subtracting the value of "10H" from the value of the data arranged at the frame position of item number 11 is OK,
Further, the item number 17 is added to the value obtained by adding each data arranged in the frame positions of the item numbers 12 to 16 for each bit.
The block check is performed by adding the value of the data arranged at the frame position of No., and if the result is OK, it is determined that the data of item numbers 1 to 10 is the second system data having no error. There is no error in the data of item numbers 12 to 16 in the system data input from the taximeter main unit 1, and the item numbers 1 to 10 and the item numbers 12 to 1
All the data of 6 and 6 are determined to be the second system data having no error.

Therefore, the system data output by the taximeter main body 1 is the first system data including only the cumulative index data of item numbers 1 to 10, or
Item number 1 in addition to the cumulative index data for item numbers 1-10
The operation information collecting device 5 collects the system data from the taxi meter main body 1 without knowing whether the data is the second system data including the cumulative index data of 2 to 16 and having a longer data length than the first system data. Even when collected, as long as there is no error in the data of the first and second system data, both are erroneously determined to have an error in the data due to the difference in the data length, and an error occurs. It is possible to prevent the first system data and the second system data that are collected without being collected from failing to be collected.

In the first embodiment described above, the first and second system data having different data lengths are output to the operation information collecting device 5 according to the setting state of the setting switch 121 of the taxi meter body 1. The case was explained, but when the target connected to the operation information collection device 5 changes,

The operation information collecting device 5 is the operation information collecting device 5 in the taxi meter system of the first embodiment.
Is configured similarly to.

Next, the operation (action) of the taximeter system of the present embodiment having the above-mentioned configuration will be described.

First, when the tariff status of the taximeter main body 1A shifts from the commercial tariff status to the empty tariff status as the empty car tariff button 105 is operated, or the taxi meter main body 1A shifts from the empty tariff status to the commercial tariff status. When the tariff display device 3 outputs a system data output request signal from the charge display device 3 via the system data transmission line 125, the taxi meter main unit 1A sends the system data transmission line 125 to the system data transmission line 125. The first system data having the content shown in FIG. 5 is output to the fee display device 3 via the.

When the first system data from the taximeter main body 1A is input in response to the request accompanying the transition of the tariff state from the empty vehicle tariff state of the taximeter main body 1A to the business tariff state, the charge display device In 3, the taxi meter 1A calculates on the second charge display portion 305,
The displayed fare is displayed. Furthermore, unit tariff buttons 307-3 for fixed charges and hourly charges 1 and 2
When 11 is operated, the corresponding charges are displayed on the first charge display unit 303, and the seven unit tariffs of the partial section surcharge, the total section surcharge, the partial section discount, and the total section discount are also displayed. When the buttons 307 to 319 are operated, the display charge of the second charge display unit 305 is updated to the charge to which the corresponding unit tariff is applied.

When the first system data is input from the taximeter main body 1A as the taxi main body 1A shifts from the business tariff state to the empty tariff state, the first taxi meter main body 1A receives the first system data. The BCC of item number 11 in the system data is changed to BCC1 to which "10H" is added and placed as it is in item number 11, and the fixed fee, hourly fee 1, 2 before the transition to the empty vehicle tariff state, Item No. 1 is the cumulative index data on the number of times each unit tariff is applied and the applicable charges for some section surcharges, all section surcharges, some section discounts, and all section discounts
2 to 25, and further, these item numbers 12 to 25
The third system data in which the block check character of each cumulative index data is arranged as BCC2 of item number 26 is output from the charge display device 3 to the operation information collection device 5 via the system data transmission line 325.

Therefore, as shown in FIG. 12, when the taximeter main body 1A is connected to the operation information collecting device 5 via the fee display device 3 and when the taxi meter main body 1A is directly connected to the operation information collecting device 5. In the case of the charge display device 3, the system data input to the operation information collection device 5 is the first system data output by the taxi meter main body 1A and the charge display device 3 having a data length longer than the first system data. There will be two types, namely the third system data to be output.

When the first system data directly from the taximeter main body 1A and the third system data from the fee display device 3 are input through the system data transmission line 125, the operation information collecting device 5 The value of the 12th data counted from the beginning is added to the value obtained by adding the 11th data counted from the beginning for each bit,
A block check is performed on the data from the header of the input system data to the item number 10, that is, it is determined whether all the added values for each bit are odd (or even).

If all the added values for each bit are odd (or even) by this block check, it is determined that the input system data is the first system data having no error in the contents. Then, the system data is taken in as the first system data, the data card writer 515 writes and records the first system data in the data memory card 7, and other necessary processing is performed.

On the other hand, if at least one of the added values for each bit does not become an odd number (or even number) by the block check of the data from the header of the input system data to the item number 10, from the beginning The value obtained by subtracting "10H" from the value of the 12th data counted is added to the value obtained by adding the 11th data counted from the beginning for each bit, and the added value for each bit is all odd ( Or a even number), the block check of the data from the header of the input system data to the item number 10 is performed in the same manner as described above.

By this block check, if at least one of the added values for each bit does not become an odd number (or even number), the input system data becomes the first
In any of the third and third system data, it is determined that there is an error in the data from the header to the item number 10, and the input data is not captured,
Instead, a system data output request signal is output to the taximeter main body 1A via the system data transmission line 125.

Further, by performing a block check of the data from the header to the item number 10 by the value obtained by subtracting "10H" from the value of the 12th data counted from the beginning, all the added values for each bit are odd (or even). ), It is determined that the input system data is the third system data and there is no error in the data from the header to the item number 10.

Then, following this, 1 counting from the beginning
Whether the value of the 27th data counted from the beginning is added to the value obtained by adding the 3rd to 26th data for each bit, and whether the added value for each bit is all odd (or even) A block check is performed on the data from the item number 12 to the item number 25 of the input system data, which is to determine whether or not.

If all the added values for each bit are odd (or even) by this block check, first, the third system data in which there is no error in the data from the header to the item number 10 is used. It is determined that there is no error in the data from item number 12 to item number 25 excluding BCC1 of item number 11 and BCC2 of item number 26 among the input system data determined to be present. The system data is taken in as second system data, and the data card writer 515 writes and records the second system data in the data memory card 7, and performs other necessary processing.

On the other hand, when at least one of the added values for each bit is not an odd number (or an even number) by the block check of the data of the item number 12 to the item number 25 from the header of the input system data, Is
BCC1 of item number 11 and BCC2 of item number 26 are excluded from the input system data that has been determined to be the third system data without error in the data from the header to the item number 10. , It is determined that there is an error in the data from item number 12 to item number 25,
The input data is not captured, and instead, the system data is output to the taximeter main body 1A via the system data transmission line 125 or to the charge display device 3 via the system data transmission line 325. A request signal is output.

With the taximeter system of the second embodiment having such a configuration, the same effect as that of the taximeter system of the first embodiment can be obtained.

In the first and second embodiments described above, the data of the item number 11 of the second and third system data generated by the taximeter main body 1 and the charge display device 3 are changed to the item numbers 1-10. This value and the item number as the value of the block check character relating to the cumulative index data of 5 plus 5 bit data larger than 4 bits which is the number of bits of this block check character, that is, hexadecimal "10". An error can be detected by a block check with the cumulative index data of 1 to 10, and the addition of the data of item number 12 or later can be detected. Further, in the first and second embodiments, the data of the final item number of the second and third system data is used as the value of the block check character for the cumulative index data of the item number 12 and thereafter, and this value and the item number. An error can be detected by performing a block check with the cumulative index data of 12 or later.

However, the present invention is not limited to the mode in which such a configuration is adopted. For example, the data of item number 11 of the second and third system data may be simply added with the data of item number 12 and thereafter. Data having a function only for detecting that the item number is 1 or the last item number of the second and third system data from the item number 1 to the item number immediately before the last one. The data may be configured to be used for error detection. However, if the configurations of the first and second embodiments described above are adopted, when it is detected from the data of the item number 11 that the data of the item number 12 and thereafter is added, the item numbers 1 to 10 are detected. This is advantageous because the error detection regarding the cumulative index data of 1 can be simultaneously performed prior to the error detection regarding the cumulative index data of item number 12 and thereafter.

Further, in the operation information collecting device 5 of the first and second embodiments, when the error detection is not necessary when the second and third system data are input, the second and third system information is obtained. Block check for the value of the character check data for the cumulative index data after item number 12 and the data from the item number 1 to the last item number before the last item number of the system data The character value data may be omitted.

When the above-described changes are made to the taximeter main body 1 or the charge display device 3, it goes without saying that the corresponding changes may be made to the operation information collecting device 5.

Further, in the above-described first and second embodiments, system data output by a meter, such as a taxi meter 1 or 1A or an external charge display device 3, which is mounted on a taxi vehicle and calculates a boarding charge or the like. However, the present invention is not limited to this and the present invention is not limited to this, for example, a driver agency installs in a companion vehicle and calculates a driver agency fee. It is needless to say that the system data output by the charge calculation meter used for is also applicable to the case where the operation information collecting device collects the system data as the operation information.
