Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing an embodiment of a taxi daily report data collection system according to the present invention. In FIG.
Is a position data collection device, and 3 is a relay device to which the time-series data collection device 1 and the position data collection device 2 are connected via the communication lines L1 and L2, respectively. Relay device 3
Is connected to a write / read (R / W) device 4 for receiving time-series data from the time-series data collection device 1 and position data from the position data collection device 2, and Is sent to the R / W device 4 and written on the recording medium 5 composed of an IC memory card or a magnetic card detachably mounted on the R / W device 4.

The time-series data collection device 1 has a data line L11 for sending index data indicating the total number of business operations related to the basic charge, the number of subsequent operations related to the charge increase, and the mileage, and the current tariff state is not shown. An electronic taxi meter 6 is connected via a wind sign (W / S) line L12 for transmitting a wind sign (W / S) signal for display on the wind sign, and has an operation key and a display unit. A handy-type operation / display unit 7 capable of viewing the display and performing key operations, a printer 8 for performing printing, and the like are connected. Note that the wind sign line L12 is extended to the relay device 3, and a W / S signal is also input to the relay device 3.

The time-series data collection device 1 generates retrieval data based on index data input from an existing electronic taxi meter in response to a retrieval key operation on the operation / display unit 7, and can write and read the retrieval data. Internal memory (RAM)
And collects it, and outputs it to the relay device 3. In addition, the time-series data collection device 1 is based on the index data and the W / S signal input from the electronic taxi meter and the running signal input from the running sensor, and is unique for each business during a period from an empty vehicle to the next empty vehicle. Then, time-series data is generated, and the time-series data is written and collected in an internal memory (RAM) that can be freely read and written. Then, in response to the entry key operation on the operation / display unit 7, entry data is generated based on the index data input from the existing electronic taxi meter, and the entry data is written into a readable and readable internal memory (RAM). The information is collected and output to the relay device 3.

The position data collecting device 2 obtains a vehicle position on map data stored in a storage medium and collects the position data. As a method for obtaining the vehicle position, a so-called GPS (Global Positioing Syst) of an absolute position detection method for detecting an absolute position by receiving a radio wave from a satellite.
em) a signal processing device, and a device including a position signal processing device of a relative position detection method of constantly detecting a constantly changing vehicle speed and azimuth and detecting a current position with respect to a departure point. Good.

When the relay device 3 receives a tariff signal indicating a commercial tariff and an empty tariff that the relay device 3 relays and outputs a W / S signal from the electronic taxi meter 6, the position data indicating the current position is received. Is generated as the boarding and disembarking place data indicating the boarding place and the disembarking place, respectively, and this is written and collected in a writable and readable internal memory (RAM). When receiving the data request signal from the relay device 3, the position data collection device 2 outputs the landing data collected in the internal memory (RAM) to the relay device 3,
Further, upon receiving the memory clear signal from the relay device 3, the terminal clears the landing data of the predetermined area.

In response to the input of the retrieval flag from the time series data collection device 1, the relay device 3 sends the retrieval flag to the R / W device 4 as it is, and sets a flag called a retrieval flag in a predetermined area in the internal memory. . This is used to determine whether or not to output a memory clear signal to the position data collection device 2 based on the state of this flag before writing the position data.

Then, as shown in FIG. 3, when the incoming data is input from the time-series data collecting device 1, it is relayed and transmitted to the R / W device 4 as it is. The completion of the normal writing from the R / W device 4 is relayed to the time-series data collection device 1 and transmitted to the time-series data collection device 1. Subsequently, the time-series data transmitted from the time-series data collection device 1 is directly transmitted to the R / W device 4. Send out.
Thereafter, the relay between the time-series data collection device 1 and the R / W device 4 is performed until an end command from the time-series data collection device 1 is received, and when the end command is received, this is transmitted to the R / W.
A normal end is transmitted to the time-series data collection device 1 without transmitting to the device 4, and then the line is switched from the R / W device 4 to the position data collection device 2 to start the position data writing process.

In the position data writing process, first, the relay device 3 outputs a memory clear signal to the position data collection device 2 when the status is "1" by checking the state of the retrieval flag, and the relay device 3 transmits the memory clear signal last time. Have the data cleared, EOT
(End Of Transmission) After receiving, set the delivery flag to "1".
From "0" to the next data request operation. If the exit flag is "0", the next data request is entered without any operation. During this process, there is a command from the time-series data collection device 1. When the command is received, the process is temporarily interrupted and the absence of a recording medium is output to the time-series data collection device 1.

Then, as shown in FIG. 4, a data request is sent to the position data collection device 2 and the position data 1 is received. Next, the received data is BCD-converted and the line is switched from the position data collection device 2 to the R / W device 4, and the BCD-converted position data 1 is transmitted to the R / W device 4 and written on the recording medium 5. When the normal write completion is received from the R / W device 4, the ACK is sent to the position data collection device 2.
, And the next position data 2 received from the position data collection device 2 is BCD-converted accordingly. At the time of the BCD conversion of the position data writing process, there is some command from the time-series data collection device 1, and when this command is received, the process is temporarily interrupted and the absence of a recording medium is output to the time-series data collection device 1. A buzzer (not shown) sounds once.

Then, B of the position data which was being converted is
Performs CD conversion, and switches the line from the position data collection device 2 to R /
Switch to W device 4 and convert BCD converted position data 2 to R
/ W device 4 for writing to the recording medium 5. R /
When the normal writing completion is received from the W device 4, an ACK is sent to the position data collecting device 2. This processing is performed on the position data N
Is repeated until the EOT is received from the position data collecting device 2. After the EOT is received, the position data flag is set to "00", the address pointer is written, and the end command is sent to the R / W device 4. If a normal end is received from the R / W device 4 in response to this, a buzzer (not shown) sounds three times. After that, the process waits for the reception data reception of FIG.

The CPU 25a clears data in a predetermined area in the RAM 25c in response to a memory clear signal input from the relay device 3, and stores position data collected in the RAM 25c in response to a data request input from the relay device 3. The data is read out and transmitted to the relay device 3.

A collection unit 25 for collecting the landing data
In the inside RAM 25c, a position data storage area for storing the landing data is formed. Now, in the position data storage area 25c ₁ of FIG. 9, the position data of the previous goods receipt is assumed to be in the state shown in (a). In addition,
Each time a data request is made, the last address A at which the transmitted position data that has been transmitted normally has been stored is stored. Thereafter position data is added is collected stored as indicated by a broken line, the position data of the current receipts immediately before is stored in the position data storage area 25c ₁ as shown in (b).

If there is a memory clear request prior to the data request at the time of entry into the warehouse, the previously transmitted address A is cleared, and the position data storage area 25c after the clear request is issued.
The position data in ₁ was collected since the last time of storage (c)
The state is as shown in FIG. Then, all the positional data from the head address of the position data storage area 25c ₁ by data request after the memory clear request is sent after transmission is completed, the last address of the current Sent as (d) B
Is stored. That is, the address pointer is changed from A to B
Will be updated to Note that if there is a tariff change that causes position information generation due to an empty vehicle → business between the clear request and the end of the current data transmission, this is ignored and taken in after the above processing.

The position data at the time of the last storage is shown in FIG.
As shown in (a), the position data storage area 25c ₁ at the time of the current storage is determined by the position data added thereafter.
When the position data of the inner is in (b), the no memory clear request, when there is only the data request, all data is transmitted from the head address of the position data storage area 25c _1, transmission After the end, the last address D which has been transmitted this time is stored.

The details of the operation of the position data collection device 2 described briefly above are described in the CPU 25 incorporated in the μCOM 25.
This will be described below with reference to the flowchart of FIG. 11 showing the processing performed by a in accordance with the control program. The CPU 25a starts operation when the power is turned on. In the first step S21, the taxi meter 6 is connected via the relay device 3.
It is determined whether or not a sales tariff based on the W / S signal has been received. When the determination in step S21 is ΝO, the process proceeds to step S22 to determine whether or not an empty vehicle tariff has been received. When the determination in step S22 is ΝO, the process proceeds to step S23, where the data request 1
Is determined. When the determination in step S23 is ΝO, the process proceeds to step S24, where the relay device 3
It is determined whether or not the data request 1 has been received from the CPU.
Returning to step 1, these steps are repeated until any of steps S21 to S24 becomes YES.

When the determination in step S21 is YES, the process proceeds to step S25, where the position data from the position recognition unit 24 is stored in a predetermined area of the RAM 25c as a boarding place, and then the process proceeds to step S23. If the determination in step S22 is YES, step S26
Then, the position data from the position recognition unit 24 is stored in a predetermined area of the RAM 25c as a drop-off location, and then the process proceeds to step S23.

The determination in step S23 is YE
In the case of S, the process proceeds to step S27 to transmit the position data, and then proceeds to step S28 to transmit the A from the relay device 3.
It is determined whether or not CK has been received, and if not, the process returns to step S27 to send the same position data. If the determination in step S28 is YES, step S2
In step 9, it is determined whether or not the transmitted position data is final data. When the determination in step S29 is ΝO, the process proceeds to step S29a to advance to the next data to be transmitted, and then returns to step S27 to transmit the next position data. The above operation is performed until the determination in step S29 becomes YES. repeat. Then, the determination in step S29 is YES
Then, the process proceeds to step S29b to send EOT, and then returns to step S21. If the determination in step S24 is YES, the process proceeds to step S29c to clear the previously transmitted position data and then returns to step S2c.
7 and the same operation as described above is performed.

As shown in FIG. 12, the relay device 3 includes a one-chip microcomputer (μCOM) 31, a plurality of interface (IF) circuits 32a to 32e,
It is composed of two selectors 33a and 33b. μCOM 31 is a central processing unit (CPU) 31a, a ROM storing control programs and various fixed data, etc.
31b and a RAM 31c. 32a of the plurality of IF circuits is the time series data collection device
32b is for connecting to the R / W device 4,
32c is for connecting the position data collection device 2 to the μCOM 31 via the selector 33a, and 32c is suitable for RS232c. 32d is for connecting the time-series data collection device 1, and 32e is for connecting the R / W device 4 to the μCOM 31 via the selector 33b. The relay device 3 connects the W / S line to the position data collection device 2 through this.

The CPU 31a of the μCOM 31 is a ROM 31
Operating according to the control program stored in b, when receiving the delivery data from the time-series data collection device 1, the data is transmitted to the R / W device 4 as it is, but a flag (delivery flag) is set in a predetermined area in the RAM 31c. . This retrieval flag is used to determine whether or not to output a memory clear signal to the position data collection device 2 depending on the state. After the receipt data is received and the retrieval flag is set, this determination is not performed until the writing of the position data is completed in order to reduce the relay processing time. Also, CPU
When receiving the incoming data from the time-series data collection device 1, the receiving device 31 a transmits the received data as it is to the R / W device 4. However, when receiving the end command, the receiving device 31 a does not transmit this to the R / W device 4. After transmitting the normal end to the time-series data collection device 1, the process starts to write the position data.

As described above, at the time of receiving the termination after receiving the incoming data from the time-series data collection device 1, the CPU 31a does not transmit this to the R / W device 4 and informs the time-series data collection device 1 of the normal end of itself. Although the transmission is started and the position data writing process is started, if the exit flag is “1”, a memory clear signal is output to the position data collection device 2 to have the previously transmitted data cleared and the exit after receiving the EOT. The flag is changed from "1" to "0" to start the next data request operation. If the exit flag is "0", the data request operation starts without doing anything.

The CPU 31a sends a data request to the position data collection device 2 to receive the position data. The CPU 31a converts the received position data into BOC data, and
After switching 3a, the R / W device 4 is accessed and written on the recording medium 5. This process is repeated until the EOT is received, and after the EOT is received, the position data flag and the address pointer are written.

The details of the operation of the relay apparatus 3 described briefly above will be described below with reference to the flowchart of FIG. 13 showing the processing performed by the CPU 31a incorporated in the μCOM 31 according to the control program. The CPU 31a starts operation when the power is turned on. In the first step S31, the CPU 31a determines whether or not command data from the time-series data collection device 1 has been received. It is determined whether the data is outgoing data. When the determination in step S32 is ΝO, the process proceeds to step S33 to determine whether or not the data is warehousing data. When the determination in step S33 is ΝO, step S34 is performed.
To perform the data relay process, and then to step S3
1 and the determination in any of steps S31 to S33 is Y
Steps S31 to S34 are repeated until ES is reached.

If the determination in step S32 is YES, that is, if the command data from the time-series data collection device 1 is delivery data, the flow advances to step S35 to change the internal release flag from 0 to 1, and then to the above-described step S34. Proceed. When the determination in step S33 is YES, that is, when the command data from the time-series data collection device 1 is the incoming data, the process proceeds to step S36 and the time-series data from the time-series data collection device 1 is processed until the end command. It relays to the W / R device 4 and then proceeds to step S37 to output a normal end to the time-series data collection device 1 after receiving the end designation. In step S38, the line is switched from the time-series data collection device 1 to the position data collection device 2.

Subsequently, the flow advances to step S39 to determine whether or not the exit flag is 1, and if the determination in step S39 is YES, the flow advances to step S39a to output a clear request to the position data collection device 2. . Next, in step S39b, after the EOT is received from the position data collection device 2, the exit flag is changed from 1 to 0. Thereafter, the process proceeds to step S39c, where a data request is output to the position data collection device 2, and the position data collection device 2
In the next step S39d, the W / R device 4 writes the position data to the recording medium 5 in the next step S39d, and then returns to the step S31. When the determination in step S39 is ΝO, the process skips steps 39a and S39b and proceeds to step S39c to output only a data request without outputting a clear request.

By the operation of the relay device 3 described above, W /
As shown in FIG. 14, time-series data collected by the time-series data collection device 1 includes, on a recording medium 5 composed of an IC memory card detachably mounted on the R device 4,

According to the above-described embodiment, FIG.
As shown in FIG. 5A, at time T ₁ , when three time-series data items are collected in the RAM 11 c in the time-series data collection device 1 by performing the business E three times after mounting the recording medium 5, At the start and end of each business, the data collection device 2 collects in and out of the RAM 25c the landing data including the six position data P of the boarding place and the getting-off place.
The collected time-series data and the boarding / disembarking data recorded on the recording medium 5 at the time of entry into the warehouse ₂ can be completely correlated by analysis by an analyzer installed in the office of the taxi company.

After the operation of the taxi vehicle shown in FIG. 15 (a), the recording medium 5 is stored at the time T ₃ as shown in FIG. 15 (b).
If the user does not perform the exit operation when re-attaching the vehicle and does not clear the contents of the RAM 11c in the time-series data collection device 1, re-operation of the taxi vehicle is started, and the sales E is performed twice to obtain two time-series data. Is additionally collected at the start and end of each business in the position data collection device 2, and boarding place data including two pieces of position data P of the boarding place and the getting off place are additionally collected. If operation of the taxi vehicle is restarted without being unloading operation after the goods receipt operation in this manner, the time-series data collecting device when not performed cleared series data RAM11c in 1, also the position data acquisition device 2 RAM 2
Since the getting-in / out place data in 5c is transmitted at the time of entry, including the data that has been transmitted previously, the time T ₄
At the time of storage, the landing data including five time-series data and ten position data is recorded on the recording medium 5 and can be completely correlated.

[0063] Further, a taxi after the time T ₅ after vehicle operation with operating E three times without recording medium 5, operating twice wearing the recording medium 5 at the time T ₆ shown in FIG. 15 (a) When E is performed, eight time-series data are collected in the RAM 11c in the time-series data collection device 1, and at this time, the getting-on / off spot data including 16 position data is collected in the RAM 25c of the position data collection device 2. Is done. In this case, since the time receipts treated retrieval operation again storage operation without after, at the time of goods receipt time T _7, it is as all data is transmitted including the data that is the previous transmission already, receipts Occasionally, getting on / off data including five time-series data and 16 position data is recorded on the recording medium 5 so that they are completely correlated.

As described above, the position data is collected by the position data collection device, and the time-series data is collected by the time-series data collection device. Then, it is sufficient to write in a predetermined area of the recording medium 5 (a user area prepared in advance as an optional area) in a batch process. The data is simply divided into a processing device or an analysis device on the office side for processing the collected data, and the daily data obtained by collecting the final data is simply processed and generated by the processing device on the office side.

[0065]

As described above, according to the present invention, the time-series data of each taxi business to be collected as part of the daily report data and the taxi business of each taxi to be collected as another part of the daily report data are provided. The getting on / off data is collected separately by a separate device, and the collected time-series data and the getting on / off data are sent out according to the data request and received and collected by the relay device. There is no need to generate and collect daily report data by adding position data to time-series data, and there is no need to perform cumbersome processing such as data conversion processing and timing adjustment that must be performed when adding this data. Without increasing the total cost of the data, the data generated by the existing electronic taxi meter and the position data collection device such as the existing GPS signal processing device Daily report data, including getting on and off site data by combining the position data to live can be easy to collect.

Also, according to the present invention, in particular, when the exit flag is set, a clear signal for clearing the previously sent / received landing data is output, the exit flag is not set, and the exit flag is not set. The data request is immediately sent out, and when the entry process is performed after the exit process, the exit flag remains set, so the previously transmitted entry / exit data is cleared and the entry / exit data is cleared. By collecting the data, it is possible to collect the landing data corresponding to the time series data of this time, and when the previous recording medium is installed without being processed after exiting after entering the warehouse, without clearing the landing data Since the terminal data including the previously transmitted terminal data is collected, the terminal data corresponding to the collected time-series data can be collected. .

Further, by operating the keys of the handy type operation means, the operations at the time of leaving and entering the taxi can be easily performed at hand.

Further, the relay device need only write and collect separately the time series data and position data for each business separately collected in the storage medium, and read the time series data into the time series data for each business for each business. There is no need to generate and collect daily report data by adding position data, and there is no need to perform complicated processing such as data conversion processing and timing adjustment that must be performed when adding this data, and the burden is extremely small. Therefore, the configuration is simple and inexpensive.
