Description

The present invention relates to a taxi operation data collection and processing system that collects and processes data on taxi operation conditions.

[Problems to be Solved by Prior Art and Invention]

The taxi is to be equipped with a taxi meter that counts and displays the fare obtained by adding the basic fare and the same fare for each fixed mileage. In addition to the basic functions described above, the taxi meter is provided with various additional functions for managing drivers, vehicles, etc. by taxi companies. This additional function is to create meter index data used by the driver to aggregate daily crew reports recorded for each business.

In the daily crew report created by the driver, the departure time, departure point, landing point, personnel, fare (cash, unpaid), operation type (radio, call stop, etc.) are recorded each time a passenger is placed. The meter index data consists of the total number of times of business, the total number of times after that, the total of operating distance, the total of total mileage, additional charge, etc., which are selectively read from the memory storing these data and displayed on the display unit. It can be displayed. Then, the driver reads these data at the beginning and the end of the daily operation and records them in the daily crew report, and the difference between them makes it easy to total the daily operation.

In addition, if you leave the recording of the meter index data to the driver, it may cause fraud, so check the record of the beginning and end of the operation with the actual meter index data indicated value with the driver. Is done by a separate person. Such a collation work must be performed for each taxi, and when the number of vehicles increases, it becomes necessary to secure dedicated personnel.

As described above, there are drawbacks such that a lot of labor is required for the driver to collect the operation data and a lot of manpower is required.

Therefore, the taximeter outputs meter index data at the end of each business, only the fare data of the data is stored and stored, and at the end of the day's operation, the stored fare data is stored. An apparatus that reduces the labor of the driver and eliminates the need for manual collation work by processing the data and the meter index data and totaling them and printing out the results is proposed in, for example, Japanese Patent Laid-Open No. 58-200385. Has been done. Since the proposed device only stores and accumulates the fare data for each business, no further information for each business can be obtained.

However, recently, in order to more thoroughly guide and manage the driver, there is an increasing demand for knowing the operating condition of each driver in each business in more detail.

Therefore, the applicant of the present application has previously proposed a taxi operation data collection device that can collect operation data showing the details of each business of a taxi including the time required for each business in time series.

However, since the data collected by the proposed device of the proposal is data representing required time, it is not possible to know the time when each business was conducted from this data.

Therefore, the present invention is intended to provide a taxi operation data collection processing system capable of collecting real time, which is a reference of collected operation data, together with operation data.

[Means and Actions for Solving Problems]

A taxi operation data collection and processing system made according to the present invention to solve the above-mentioned problems is installed in a taxi, and at the time of business consisting of data representing the time required for the period from the end of the previous business to the end of the business. A taxi operation data generation / storage device A that generates and stores series data,
Data including a taxi operation data collection processing device B installed at a place for collecting and processing taxi operation data, and the taxi operation data collection processing device B having time data generation means 6e for generating taxi reference time data. A data collection / storage means 6 is provided, and the data collection / storage means 6 is
At the time of inputting data from the taxi operation data generating / accumulating device A mounted in a taxi, the time data was read from the time data generating means 6e, and the read time data and the taxi operation data generating / accumulating device A were input. It is characterized by collecting and accumulating data and.

In the above configuration, when a taxi enters and data is input from the taxi operation data generation / storage device A to the taxi operation data collection / processing device B, the reference time data generating means 6e generates the data together with this data. Since the data collection and storage means 6 in the taxi operation data collection processing device B collects and stores the time data,
It is possible to know the time of each business by performing back calculation using the above-mentioned reference time data as the reference time of the time-series data of each business, which is the data representing the time required for each business.

〔Example〕

An embodiment of a taxi operation data collection processing system according to the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing in detail the entire configuration of the taxi operation data collection processing system according to the present invention, particularly the configuration of the taxi operation data generation / storage device. In the figure,
The taxi operation data generation / accumulation device has an operation data generation unit 1 and an operation data collection unit 2, and is installed in a taxi.

The operation data generation unit 1 including an existing electronic taxi meter includes a central processing unit (CPU) 1a that operates according to a predetermined program to perform signal processing, a tariff switching unit 1b that switches a tariff state of a taxi, and a charge. A charge indicator 1c for displaying, a memory 1d composed of a CMOS random access memory (RAM) for storing meter index data and the like, a window sign 3 for displaying a tariff state.
In addition to the wind sign driver 1e for driving, a read-only memory (ROM) (not shown) for storing programs and constants, an index display for displaying meter index data, and index data for display on the index display are selected. It has a selection means.

The tariff switching unit 1b accepts tariffs, surcharges, fare, empty cars,
It is composed of a plurality of tariff switches for switching to a payment state, and the tariff state switched by the tariff switching unit 1b is input to the CPU 1a. The CPU 1a is connected to a travel sensor 4 which generates one distance pulse each time a taxi travels a certain distance.

The CPU 1a processes the distance pulse from the travel sensor 4 by the tariff status signal from the tariff switching unit 1b and a predetermined fare system to calculate the charge for each business and display the charge on the charge display 1c. , The wind sign driver 1e is operated to display the tariff state on the wind sign 3.

The CPU 1a also sums up the charges of each business, the total of business hours, the total of business travel times, the total of travel times, the total of the number of intercepted vehicles / idling distances, the total of travel distances, the total of business travel distances, and the following. The meter index data such as the total number of times (the number of times exceeding the basic charge) and the total number of business operations is created and stored in a predetermined area of the memory 1d, and these meter index data are put into the empty tariff state of the tariff switching unit 1b. In addition to serially outputting in a predetermined format in accordance with the switching of, the contents are selectively displayed one by one on the index display by the selection means.

The CPU 1a raises the strobe signal prior to the output of the serial data, and notifies the data collection unit 2 which is the recipient of the serial data that the serial data will be output, and the output of the serial data is in the empty tariff state. Even if there is no switching to, it can be performed in response to a data request from the outside. The electronic taxi meter itself is well known and will not be described further, but FIG. 3 shows the frame structure of the meter index data transmitted from the operation data generator 1 to the data collector 2. In Fig. 3, the meter index data is the code of the vehicle equipped with the taxi meter, the charge for each business,
Business hours of the vehicle, business travel time, travel time, number of intercepted vehicles / idling distance, total travel distance, business travel distance, number of times after the same,
It consists of the number of sales.

The data collection unit 2 is the third one generated by the operation data generation unit 1.
Business time-series data as shown in Fig. 4, which represents the operating status of taxis for each business, is created from the data in the figure and the data that is independently measured and created. And outputs the collected time series data. For this purpose, the data collection unit 2 includes a CPU 2a that operates according to a predetermined program, a memory 2b that is a CMOS RAM that stores time series data, and a CPU 2a.
And a backup power supply 2c for backing up the operation of the memory 2b.

The data collection unit 2 also has an unpaid switch e. The unearned switch 2e is for collecting as data whether or not the business concerned is unearned, and when the switch is turned on,
The unpaid bit in the special plug of the time series data is set to 1. The operation of the uncollected switch is limited to the case where the ACC is on and the uncollected lamp 2f is lit. And
When the switch input is accepted, the uncollected lamp 2f is turned off. That is, it means that the uncollected lamp 2f can accept the uncollected switch 2e while the uncollected lamp 2f is on, and it cannot represent the uncollected switch 2e when unlit. Then, once the uncollected switch 2e is received, the uncollected lamp 2f is turned off and is not turned on until the next business is started.

In Fig. 4, the business time-series data is a detailed description of required time for each business, empty vehicle stop time, each tariff time, number of empty vehicle stoppages, empty vehicle travel and stop time, in addition to the meter index data from the operation data generation unit 1. , Actual vehicle / empty vehicle maximum speed, actual vehicle / empty vehicle speed overtime and number of times, and special flag.

The CPU 2a inputs a wind sign signal indicating a tariff state, a distance pulse from the running sensor 4, a strobe signal and serial data from the operation data generator 1 including an electronic taxi meter, and inputs these according to a predetermined program. A data request signal generated when the business time series data of FIG. 4 is created by performing signal processing, the business time series data is stored in the memory 2b, and the plug 2d which is the output means is inserted into the terminal 5. In response to this, the time series data stored in the memory 2b is output to the terminal 5 through the plug 2d. Further, the data collection unit 2 sends a request signal input through the plug 2d to the operation data generation unit 1 at the time of leaving the garage and at the time of entering the garage to read the meter index data from the operation data generation unit 1, Based on the above, the entry / exit data having the frame structure shown in FIG. 5 is created and stored in the memory 2b.

In FIG. 5, the entry / exit data is almost the same as the meter index data in FIG. 3 except for the required time and the input flag.

As described above, the time-series data read from the storage unit 2b and transmitted to the terminal 5 through the plug 2d in response to a request from the outside has a frame structure as shown in FIG. That is, the time-series data transmitted to the terminal 5 includes the delivery data and entry data following the header indicating the beginning of the data, and the business time-series data 1 to 1 arranged in the order of business.
n, horizontal parity, and an end mark indicating the end of data.

The time-series data transmitted to the terminal 5 is temporarily collected in the repeater 6 together with data from other terminals (not shown) and subjected to data processing by, for example, an office computer (not shown) provided in the office,
This makes it possible to understand the daily operating status of all vehicles of the taxi company.

The CPU 2a of the data collection unit 2 operates according to a predetermined program, and has an index data reading function, a time series data writing function, a time series data plug output function, a required time measuring function, an empty vehicle stop time measuring function, and an empty vehicle stop detail measurement. Function, measurement of number of times of empty vehicle stop, measurement function of actual vehicle / empty vehicle maximum speed, measurement function of actual vehicle / empty vehicle speed over time, measurement function of actual vehicle / empty vehicle speed over number, tariff time measurement function, uncollected switch processing function Has become.

The above functions will be described below in order.

(Index data read function) To read the index data, output the data request because the operation data generator 1 generates a strobe signal before the index data is output when the taxi meter tariff becomes empty. However, when the plug 2d is inserted into the jack 5a of the terminal 5 when the vehicle is empty, a data request is output and the operation data generating unit 1 generates and reads the index data.
If the read data has an error, the data is read again a predetermined number of times.

(Time-series data writing function) The time-series data is composed of shipping data, receipt data, and business time-series data created for each business as described above with reference to FIG. The delivery data has the same content as the previous delivery data, and is created at the start of the first business after the plug-in. The warehousing data is created at the time of plug-in, and is composed of the meter index data and the required time at that time. The business time-series data is created at the end of each business and is composed of a meter index, required time, idle time, etc.

The memory 2b has, for example, the maximum number of data that can be stored, for example, sales 1
It has a capacity of 00 times.

(Time-series data plug output function) When the plug 2d is inserted into the jack 5a of the terminal 5 when the taxi ignition key is in the ACC ON state and the car is empty, the data stored in the memory 2b until then is plugged together with the receipt data. (2) It is transmitted to the terminal 5 through d. The data is repeatedly sent while the plug (2) d is inserted.

(Required time measurement function) As shown in FIG. 7, the required time in the receipt data is the time from the end of the final business to the plug-in. The time required for the first business time series data is the time from the final plug-in to the end of the first business. The time required for other business time series data is the time from the end of the previous business to the end of this business. The final plug-in will be judged when the first business starts.

Time measurement is performed by a software counter that uses a 1-second clock as a basic clock. The software counter is
For example, it is composed of a 60-second counter (first stage) and a BCD counter (second stage-maximum 9999 minutes). When the measurement time exceeds 9999 minutes, continuous counting is performed from 0 minute. Data is read only in minutes, and seconds are truncated.

The actual required time is calculated by using the previous BCD counter memory and obtaining the difference between the present counter value and the previous counter value. This is because the rounded down amount at the previous business is not accumulated. The previous counter value is updated with the current count value after the calculation process at the end of business and after the plug-in process. The software counter is cleared at the end of the first business. As a result, an error of -1 to +1 minutes occurs for each business, but the total error in one operation can be kept within the range of -1 to +1 minute.

(Vacancy stop time measurement function) The idle car stop time is defined as follows.

In the case of the first business time-series data in one operation (departure data), it is the total stop time in the empty vehicle from the last plug-in performed at the time of departure to the first business end.

In the case of from the last business close to the plug-in in one operation (warehousing data), it is the total stop time in the empty car from the last business close to the plug-in.

In the case of a plug-in to a plug-in, that is, when the plug-in continues for a plurality of times, the total stop time in an empty vehicle from the plug-in to the plug-in is used.

For other business time-series data, the total stop time in the space from the previous business close to the current business close.

It should be noted that one operation means from delivery to receipt, and in this example, from the last plug-in of the previous operation to the plug-in just after the last operation. Further, stop means continuous stop for a stop determination reference time or longer.

The stop determination reference time is, for example, 0, 1, 2, 3, 5, 1
0,15,20,25,30,35,40,45,5
A total of 16 types of settings for 0, 55, and 60 minutes are possible.

Time measurement is based on the condition that it is a simple stop with an empty car. 6
0 second counter (1 second clock software counter) and BCD counter (4 digits BCD-9999 maximum)
Minutes). If one or more distance pulses are input from the travel sensor 4 in one second, the vehicle travels for the next one second. Therefore, simple stop means a state in which there is no pulse from the travel sensor 4 in one second. When the measurement time exceeds 9999 minutes, counting is continued from 0 minutes.

The empty vehicle stop time is set in the business time series data at the end of each business, and the BCD count value counted in minutes is recorded as it is. Therefore, the data in units of seconds will be ignored. Also, after recording BC
The D counter is cleared, but the 60 second counter is not.

At the end of the first business, the 60-second counter is also cleared, so that the end of the first business becomes the reference for the next measurement.

In the case of a stop in an empty car that does not reach the standard, the 60-second counter is cleared, but in the case of the standard or more, the unit data is stored in memory and this is added when the stop in the next empty car or more occurs. I am trying.

(Measurement function of empty vehicle stop details) In one data, the data for three times of continuous stopping time of the taxi when the vehicle is empty is stored in the order of occurrence. In creating this specification, the stop determination reference time is not provided, and the upper three data are always stored.

(Function to measure the number of vacant car stops) Counts the number of times a taxi stops when a car is vacant for a certain period of time or more. Stop judgment reference time setting is
It is the same as the empty vehicle stop reference time, and when the setting is 0 minutes 0 seconds, the number of times is not counted.

(Measurement function of empty vehicle / empty vehicle maximum speed) The number of pulses from the running sensor is counted every second, and the maximum value within the measurement range time is stored. Then, at the time of recording the business time series data, the maximum value is converted into a speed and recorded.

(Actual vehicle / empty vehicle speed over time measuring function) When counting the number of pulses per second, if the number of pulses is greater than or equal to the set value, the over time counter is incremented by +1. There are four speed settings, for example 60, 70, 80, 90 km / h. The maximum measurement time is 9999 minutes, rounding up less than 30 seconds for minutes and rounding down for less than 30 seconds.

(Measurement function of the number of actual vehicle / empty vehicle speed overs) The number of actual vehicle / empty vehicle space speed overs in one data is measured. When the speed is equal to or higher than the speed set value at the speed judgment timing after 1 second, +1 is counted.
The maximum number of measurements is 9999.

(Tariff time measurement function) For each business, the time required for rent, 20% increase, payment, and arrival is measured and recorded as part of the business time series data. The time is measured by the CPU detecting the 1-second clock and counting up the tariff counter corresponding to each tariff. Tariff counter is 60 seconds counter and BCD
It consists of a counter (4 digits-maximum 9999 minutes).

Recording is performed at the end of each business. At that time, the 60-second counter value is rounded down to 29 and the BCD counter value is stored as it is in the business time-series data. All the tariff counters are cleared when the above storage is completed.
When the BCD counter exceeds 9999, the count continues from 0.

The operation of the CPU 2a of the data collection unit 2 having the above-mentioned functions will be described below with reference to the flowchart shown in FIG.

The CPU 2a starts its operation by connecting the power source, and in the first step S1, the ACC of the ignition key is set.
It is determined whether or not is on. If the determination in step S1 is Y
In the case of ES, the process proceeds to step S2, where the power-on flag is set, and then the plug 2d is set in step S3.
Is in the plug-in state, which is inserted in the jack 7 of the terminal 5. Not a plugin
If the determination is NO, then the process proceeds to step S4, where it is determined whether or not business is in progress. This determination is made based on whether or not the tariff sign signal is other than an empty vehicle. If not, the determination becomes YES and the process proceeds to step S5.

In step S5, the power-on flag is cleared, and then in step S6, it is determined whether or not there is a plug-in flag. If the flag is present and the determination is YES, it is determined that it is the first business and the process proceeds to step S7, where the plug-in flag is cleared, and then the process proceeds to step S8 where all the business time series data stored in the RAM 2b is cleared, In a succeeding step S9, a data request is sent to the operation data generating unit 1 to read out the operation index data, based on this, delivery data is created and the process proceeds to step S10. Step S4
If the determination is NO, that is, if it is the second or subsequent business, steps S7 to S9 are skipped and the process proceeds to step S10.

In step S10, the index data reception flag is cleared because the index data is received from the operation data generation unit 1,
In the subsequent step S11, the time-series data creation flag is cleared and the required time clear flag is cleared in the subsequent step S2. Then, it progresses to step S13 and it is determined here whether the uncollected acceptance lamp 2f is lit, and a determination is YES.
If so, the process proceeds to step S14, where the uncollected switch 2
It is determined whether or not e is turned on.

When the determination in step S14 is YES, the unpaid bid of the special flag of the current business time series data is set to 1 in the following step S15, the unpaid acceptance lamp 2f is turned off in the following step S16, and the process proceeds to step S17. When the determination in step S13 or S14 is NO, steps S15 and S16 are skipped and the process proceeds to step S17.

In step S17, it is determined whether or not the uncollected bit has been set. If the determination is NO, step S17
After turning on the uncollected acceptance lamp 2f in step 18, if the determination is YES, step S18 is skipped and step S1 is performed.
Proceed to 9.

In step S19, it is determined whether or not the business is renting,
If the determination is YES, the process proceeds to step S20, and the rent time is measured. After that, the required time is measured in step S21, the actual vehicle high speed is measured in step S22,
In step S23, measuring the actual vehicle speed over time,
In step S24, the number of times the actual vehicle speed is exceeded is counted, and the process returns to step S3.

As long as the determination in step S1 is YES, the determination in step S2 is NO, the determination in step S3 is YES, and the vehicle is in the renting state, steps S1 to S5, S1
0 to S24 are repeatedly executed. And step S4
When the determination is NO, that is, when the vehicle is empty, the process proceeds to step S25, where it is determined whether the power-on flag is present. The determination in this step is NO because the flag has been cleared in step S5, and as a result, the process proceeds to step S26. In step S26, it is determined whether or not the operation data has received the index data from the generator 1, depending on whether or not the index data reception flag is present. When the index data is received and the determination is YES, the step index data reception flag has been cleared in step S10, so the determination in step S26 this time is NO, which causes the process to proceed to step S27.

In step S27, the index data generated by the operation data generator 1 when the tariff switching is switched to the empty vehicle is received, and then the index data reception flag is set in step S28. After step S28, step S
In step 29, it is determined whether or not there is a business time series data creation flag. If the determination in step S29 is no, the process proceeds to step S30, where business time series data is created. After that, the process proceeds to step S31, where the unpaid flag is cleared this time, and then the business time series data creation flag is set in step S32, and step S3
Go to 3. If the determination in step S29 is YES, steps S30 to S32 are skipped and the process proceeds to step S33.

In step S33, it is determined whether or not the required time clear flag is present. If the determination is NO, the process proceeds to step S34, where the required time is cleared. After step S34, the process proceeds to step S35, where the required time clear flag is set, and the process proceeds to step S36. Step S above
If the determination in 33 is YES, steps S34 to S35.
And skip to step S36.

In step S26, it is determined whether or not the uncollected receipt lamp 2f is turned on, and when the determination is YES, step S3
7, the process determines whether the uncollected switch 2e is turned on. When the determination in step S37 is YES, the process proceeds to step S38, in which the unpaid bit of the previous business time series data is set to 1, and the subsequent step S39.
In step S4, the uncollected acceptance lamp 2f is turned off.
Go to 0. When the determination in step S36 or S37 is NO, steps S38 to S39 are skipped and the process proceeds to step S40.

In step S40, the details of the empty vehicle running time are measured, then in step S41, the specification of the empty vehicle stop time is measured, in step S42, the empty vehicle reconsideration speed is measured, in step S43, the empty vehicle speed overtime is measured, and in step S44, the empty vehicle speed over count is displayed. Counting, measuring the required time in step S45, measuring the idle vehicle stop time in step S46, counting the number of idle vehicle stop times in step S47, and then returning to step S3.

In the above description, the vacant car is emptied directly from the fare, but this does not occur in reality, and payment is made at the end of the fare, so the determination in step S19 is NO, and 2
After step S48 for determining whether or not to pay the premium, the process proceeds to step S49, where it is determined whether or not to pay.
If this determination is YES, the payment time is measured in step S50 and then the process proceeds to step S21.

Further, in the case of 20% increase, the determination in step S48 is YES.
Then, the process proceeds to step S51, the 20% additional time is measured, and then the process proceeds to step S21. If it is neither a rent, a 20% increase, or a payment, the process proceeds to step S52, where it is determined whether or not the vehicle is an intercepting vehicle. When the determination is YES, the intercepting time is measured in step S53, and then the process proceeds to step S21. .

When the determination in step S1 is NO, that is, ACC
When is off, the process proceeds to step S46. When the determination in step S3 is YES, that is, when the plug-in is performed, the process proceeds to step S54, where it is determined whether or not the business is in progress. The determination in step S54 is YES
If NO, return to the start; if NO, step S55.
Proceed to.

In step S55, a data request is sent to the operation data generator 1 to read out the index data, and then step S55.
In 56, business time series data is created, and in subsequent step S57, warehousing data is created. Then, the plug-in flag is set in step S58, and the required time is cleared in subsequent step S59. Next, the process proceeds to step S60, where the outgoing / incoming data and the time series data are sent to the terminal 5 through the plug 2d.
This transmission of data is repeated until it is determined in the subsequent step S61 that the plug-in has been exhausted. When the plug 2d is pulled out from the jack 5a of the terminal 5, the process returns to the start.

As is clear from the above description, the operation data generation unit 1 and the operation data collection unit 2 are installed in a taxi, and are included in data indicating the time required for the period from the end of the previous business to the end of the business. A taxi operation data generation / storage device A that generates and stores series data is configured.

Although the terminal 5 and the repeater 6 are shown as a single block in FIG. 2, each has a microprocessor and has various functions. Further, the processing unit 7 can be configured by a personal computer equipped with a printer, a keyboard, a CRT and the like. The terminal 5, the relay device 6, and the processing unit 7 constitute a taxi operation data collection processing device B installed at a place where taxi operation data is collected and processed.

As shown in FIG. 9, the terminal 5 has a jack 5 into which the CPU 5b and the plug 2d of the operation data collection unit 2 are inserted.
an input unit 5c having a, a transmission / reception unit 5d for performing transmission / reception with the repeater 6, a journal printer 5e, a display unit 5f,
It has an indicator 5g, a completion switch 5h, etc., which is installed at an appropriate place in the garage of the taxi company.

Prior to inserting the plug 2d into the jack 5a, a rampen carrying the crew code carried by each cabin is inserted, so that the data transmitted through the plug 2d can be identified as which crew's operation data. There is.

The terminal 5 has the following functions.

Detects that the plug 2d is inserted into the jack 5a,
In response to this, the device itself enters a standby state and outputs a data request signal. Following the data request signal, the data transmitted through the plug 2d and the jack 5a is received. Whether or not the received data is normal is determined and the result is indicated by the indicator 5g. If the received data is abnormal, the data is received again. When the completion switch 5h is operated by knowing that the received data is normal from the lighting of the indicator 5g, this is transmitted to the repeater 6.

When the timing of data transmission to the repeater 6 coincides with that of another terminal, or when the repeater 6 is transmitting data to the processing unit 7, it waits temporarily and indicates this by a special display on the display 5f. .

The data transmitted to the repeater 6 is processed by the repeater 6 and returned. The return data includes sales amount, unpaid amount, receipt index, delivery index, deduction index, date, etc. Of these, the sales amount and unaccounted amount are displayed on the display 5f, and the rest are Journal printer 5
Print out with e.

The detection of the plug 2d into the jack 5a is shown in FIG.
As shown in (a), the plug 2d itself includes the light emitting diode 5a-1 and the phytotransistor 5a-2 in the jack 5a.
When the plug insertion is detected, the CPU 5b of the terminal 5 enters a standby state for receiving data from the plug 2d. After the plug insertion is detected, when the plug 2d further enters the jack 5a as shown in FIG. 10 (b), the jack 5d
The magnet 5a-3 in a turns on the reed relay 2d-1 in the plug 2d. This reed relay 2
When d-1 is turned on, it becomes a data request signal to the CPU 2a of the operation data collection unit 2, and the CPU 2a starts data transmission after a predetermined time according to the request signal.

The reed relay 2d-1 is turned on after the CPU 5b of the terminal 5 is in a data reception standby state, and then the light emitting diode 2d-2 at the tip of the plug 2d sends data in the form of an optical signal. The phototransistor 5a-4 receives the signal and inputs it to the CPU 5b. The CPU 5b reads data for one frame. An error will occur if data is not sent within 3 seconds after the CPU 5b enters standby or if there is a data interruption of 3 seconds or more during data reception.

When the reading of the data for one frame is completed, the data is checked, if there is an error, the data is received again a predetermined number of times, and if there is still an error, NG is indicated by the indicator 5g and the error is given. The message is printed out by the printer 5e.

When the crew member code and time-series data are normally input, the crew member code is displayed on the display 5g, and OK is instructed by the indicator 5g, and then the transmission with the repeater 6 is started. The transmission is started by the completion switch 5h. The format of the data transmitted from the terminal 5 to the repeater 6 is as shown in FIG. The sales amount and the like are calculated in the repeater 6 based on this data, and necessary data is returned to the terminal 5. The format of this data will be described later. When the data is returned from the repeater 6 to the terminal 5, the sales amount and the unpaid amount are displayed on the display device 5g, and necessary items are printed out by the printer 5e. When the return data from the repeater 6 includes area overflow information, the terminal displays 6 on all digits of the display 5f to notify the crew. This display is performed for 30 seconds, and if the plug 2d is inserted during that time, the display disappears at that point.

As shown in FIG. 12, the repeater 6 includes a terminal-side transceiver 6b that transmits and receives data between the CPU 6a and a terminal, and a processor-side transceiver 6c that transmits and receives data to and from the processor 7. , RAM 6d, clock 6e, etc., and is installed in the office of the taxi company together with the processing unit 7. The repeater 6 has a clock 6e as a time data generating means for generating reference time data of a taxi, and when the data is input from the taxi operation data generating / accumulating device A mounted in the taxi, the time is transmitted from the clock 6e. It functions as a data collecting and storing means for reading data and collecting and storing the read time data and the data inputted from the taxi operation data generating and storing device A.

The repeater 6 has the following functions.

The basic charge data is received from the processing unit 7 and stored.

When the data is received from the terminal 5, the current day sales amount is calculated based on the entry / exit index data. After this processing is completed, the necessary data in the format shown in FIG. 13 is returned to the terminal 5.

The same-day data shown in FIG. 11 and the above-mentioned processed data received from the terminal are stored in the RAM until the processing unit 7 requests transmission.
6a, and after sending data on demand, RA
Clear M6d. After sending this data, a flag indicating that the goods have been stored is entered in the data.

The processing at the repeater 6 is performed by inputting data from the terminal 5,
The processing and return to Terminal 5 are given top priority,
Data output to the processing unit 7 is performed by using the idle time. However, when the data transmission to the processing unit 7 has started, the request from the terminal 5 is not accepted during the transmission period for one vehicle.

The repeater 6 incorporates a clock 6e and adds time data to the data input from the terminal 5 for each plug-in.

This time data can be used as a reference time when the processing unit 7 converts the time series data including the data representing the required time into the real time data.

The repeater 6 controls a plurality of terminals as follows. Normally, the SRQn signal from the terminal 5 and the polling (ENQ2) signal from the processing unit 7 are repeatedly monitored, and processing is performed from the earlier detected one of those signal sources.
When transmission requests are simultaneously issued from a plurality of terminals, the processes are performed in ascending order of the terminal number, and other transmission requests are not accepted until the processes of all the terminals are completed. However, the NAK signal for the ENQ signal from the processing unit 7 is returned every time one terminal process is completed.

When receiving the selecting code (ENQ1) signal from the processing unit 7, the repeater 6 concentrates on receiving the fee file data from the processing unit 7 and does not perform any other processing. Therefore, the SRQ signal from the terminal 5 is not accepted until the data reception from the processing unit 7 is completed.

The transmission between the terminal 5 and the repeater 6 will be described in more detail. When the completion button 5b is operated in the terminal 5, the transmission request (SRQ) signal is output from the terminal 5 into the repeater 6 in response thereto. After that, Terminal 5
Has a transmission permission (RQ) signal from the repeater 6, and first outputs the entry / exit index to the repeater 6. When the transmission of the entry / exit index for one frame is completed, the terminal 5 monitors the RQ signal from the repeater 6, and if it detects ON of the RQ signal within a certain time, outputs the data to the repeater 6 again. To do.
When the ON of the RQ signal is not detected within a fixed time,
After assuming that the data has been sent normally, the SRQ signal is turned off, and then the reply from the repeater 6 is waited for. When the reception of the return data of one frame from the repeater 6 is completed, various checks are performed. If the data is abnormal, the SRQ signal is turned on and the return data is received again.

The above is shown in a timing chart as shown in FIG.

In the figure, t ₁ is the time when the SRQ signal is turned on at the terminal and the data transmission (RV) signal is on standby. t ₂
Is the ON time of the RQ signal due to the detection of the SRQ signal in the repeater 6. t ₃ is the time point at which the initial transmission of data is started by detecting the RQ signal at the terminal 5. t ₄ is an RQ signal OFF time after the first word of the initial transmission data is read in the repeater 6, t ₅ is an initial transmission data end time in the terminal, t ₆ is an RQ signal ON time due to an error detection in the repeater 6, t ₇ is a retransmission data transmission start time at the terminal 5, t ₈ is an RQ signal off time after the first word of the retransmission data is read at the repeater 6, t ₉ is a retransmission data transmission completion time at the terminal, and t ₁₀ is the repeater 6
At the time of standby of the data transmission (SD) signal after completion of the error check in t, t ₁₁ is a time when the RQ signal is not detected within a certain time in the terminal 5 and both the SRQ signal and the RV signal are turned off, t ₁₂ / t ₁₄ is T ₁ is the repeater 6 when the return data is transmitted from the repeater 6 after the SRQ signal is detected, when the return data is completed, and when the SRQ signal is not detected within one time.
Data processing time.

Note that FIG. 15 is text data to which necessary data is added in the repeater 6 and transmitted to the processing unit 7.

CPUs 5b and 6 of the terminal 5 and the repeater 6 described above

First, the CPU 5b of the terminal 5 starts its operation by connecting a power source, and in the first step S101, determines whether or not a rampen has been inserted. This step S
101 is repeated until the rampen is inserted. When the rampen is inserted and the determination in step S101 is YES, the process proceeds to step S102, where crewmember data is read from the rampen. The read data is checked, and it is determined in the next step S103 whether or not there is an error.

If there is no error and the determination in step S103 is NO, the process proceeds to step S104, where the crew member code is displayed on the display 5f. After that, in step S105, the plug 2d
Is inserted, and step S105 is repeatedly executed until the plug 2d is inserted. When the determination in step S105 is YES, that is, the plug 2d
When is inserted, the process proceeds to step S106, where the time series data stored in the RAM 2b of the operation data collection unit 2 is read, the read data is checked, and the data is temporarily stored in a memory (not shown).

After that, the process proceeds to step S107, where it is determined whether or not there is an error as a result of the above check. If the determination is YES, NG is instructed by the indicator 5g in step S108, and the process returns to step S101.

If the judgment in step S103 is YES and there is a rampen error, the process proceeds to step S109, where after the rampen error is indicated by the indicator 5g, the rampen insertion is confirmed in step S110, and in the subsequent step S111. Read the data from Lamphun. After that, the process returns to step S102 and the above determination is performed again.

When the determination in step S107 is NO, that is, when there is no error in the data read through the plug 2d, the process proceeds to step S112 and the OK indicator 5 is displayed.
At the same time as instructing by g, data of the format as shown in FIG. 11 to be transmitted to the repeater 6 is created in the following step S113. Then, in step S114, it is determined whether or not the completion switch 5h is turned on. When the completion switch 5h is turned on, the process proceeds to step S115, where the indicator 5g indicates that the process is in progress, and the subsequent step S116. At, data is transmitted to the repeater 6.

Then, in step S117, it is determined whether or not the relay 6 has an error in the data. If the determination is YES and there is an error, the process returns to step S101. When the determination is NO and there is no error, the process proceeds to step S118 and the repeater 6
Receive return data from. The received return data is checked, and it is determined in step S119 whether there is an error as a result.

If the determination in step S119 is NO, that is, if there is no error, the process proceeds to step S120, in which the total receipt, unpaid amount, and crew code in the return data are displayed on the display device 5f.
And the necessary data is printed out by the printer 5e in the following step S121.

When the determination in step S119 is YES, that is, when there is an error, the error is the R of the repeater 6.
Whether or not the AM area is over is determined in step S122.
If the determination is NO, the determination is NO at step S123.
Then, the error is printed and the process returns to step S1. Judgment is Y
In the case of ES, that is, in the case of area over, 8 is displayed blinking in step S124. This display is 30 in step S125 unless the rampen is inserted.
Wait for a second and return to step S101.

Next, the CPU 6a of the repeater 6 starts its operation by connecting the power source, and in the first step S201, it is determined whether or not there is a transmission request from the terminal 5. When the determination in step S201 is no, the process proceeds to step S202 and it is determined whether or not there is a reception from the processing unit 7. If the determinations in steps S201 and S202 are both NO, step S is performed until one of the determinations is YES.
201 and S202 are repeatedly executed.

If the determination in step S201 is YES, the process proceeds to step S203 to calculate which terminal the transmission request is from, and then in step S204, the clock 6
Read clock data from e. Then, step S20.
In step 5, data is received from the terminal, and it is determined in step S206 whether or not there is an error in the received data. If there is no error and the determination is NO, then in step S207, there is a vacancy in the storage area of the RAM 6d. If it is YES, the total revenue, unpaid amount, etc. are calculated in step S208, and the calculation result and necessary data are returned to the terminal in step S209.

If the determination in step S206 is YES, that is, if there is an error, and if the determination in step S207 is NO, that is, if there is no free space in the area, error processing is performed in step S210 and then the process proceeds to step S209 to return data to the terminal. To do. After returning the data, step S2
In 11 it is determined whether or not there is an error in the returned data, and if the determination is NO, in step S212 the processing unit 7
Data to be sent to and stored in the RAM 6d.
Then, in step S213, the next terminal is designated, and then in step S214, it is determined whether or not there is an unprocessed terminal 5 transmission request. When the determination is YES, the NAK signal is transmitted to the processing unit 7 in step S215, and then the process returns to step S203.

When the determination in step S211 is YES, steps S212 to 213 are skipped and the process proceeds to step S214. If the determination in step S214 is no, the process returns to step S201.

When the determination in step S202 is YES, the process proceeds to step S216, where it is determined whether the request is a transmission request. When the determination is NO, it is determined in step S217 whether or not the request is a reception request. When the determination in step S217 is NO, the process returns to step S201.

If the determination in step S216 is YES, the data is received from the processing unit 7 in step S218, and
At 219, it is determined whether there is an error. Judgment is YES
If so, the process returns to step S201. If NO, the process proceeds to step S220, where the received data is stored in the RAM 6a, and then the process returns to step S201.

If the determination in step S217 is YES, it is determined in step S221 whether or not there is data to be transmitted to the processing unit 7. If YES, the data is transmitted in step S222, and if NO, the EOT signal is transmitted in step S223. Is transmitted, and the process returns to step S201.
