DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taxi daily report data collection system for collecting daily report data including time series data for each taxi business and getting on and off place data.

[0002]

2. Description of the Related Art Conventionally, as a daily report data collection system of this type, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 4-24787, a navigation system for obtaining a vehicle position on map data stored in a storage medium has been used. 2. Description of the Related Art There is known a vehicle in which vehicle position data during traveling is called and stored in a memory in an electronic taxi meter together with business traveling data such as a fee at that time.

However, in the case of this system, a tariff setting input means composed of a plurality of switches for setting an empty vehicle, a rented ride, a surcharge, a pick-up vehicle, and other tariffs, a tariff in business operation, and other tariff positions are used. A navigation system is provided in an electronic taxi meter having display means for displaying, and data calculation means for performing a charge calculation according to the current tariff position based on the travel distance and the travel time, and displaying the charge at the time on the display means. It is necessary to provide a memory for storing the daily report data in addition to a function to call the vehicle position data relating to the place of getting on and off of each business, and a function to generate daily report data consisting of vehicle position data and business travel data such as tolls at that time. Therefore, it is not possible to collect daily report data using existing electronic taxi meters as they are.

Therefore, conventionally, the number of sales, the number of
The index data indicating the total running distance and the like and the wind sign signal for displaying the current tariff state are input from the existing electronic taxi meter, and the running signal is input from the running sensor to allow each business (from empty vehicle to next A time-series data collection device that is configured to collect time-series data independently generated for each time period until an empty vehicle is stored in an IC memory card as a storage medium.
A position data generating means such as a PS (Global Positioning System) signal processing device is connected, and the time series data collection device reads the position data from the GPS signal processing device for each business, and reads this position data for each business. It is considered that daily report data is generated and collected by adding to data.

However, even in such a configuration, the GP
An interface circuit that performs a task of converting data received from the S signal processing device into, for example, a three-digit map code, and delays a business signal and a tariff signal when the next business operation is performed at the time of entering a disembarkation place. Since it becomes necessary, the load on the interface circuit becomes very large, the configuration of the interface circuit becomes complicated and expensive, and there arises a problem of increasing the total cost of the system.

Therefore, without increasing the total cost of the system, it is possible to easily combine the data generated by the existing electronic taxi meter and the position data generated by the existing position data generating means to easily generate the daily report data including the landing data. A taxi daily report data collection system having a configuration as shown in FIG. 11 has been proposed.

In FIG. 11, a taxi daily report data collection system uses an index data and a tariff signal input from an existing electronic taxi meter 6 and a travel signal input from a travel sensor 12 to output a taxi from an empty vehicle to the next empty vehicle. Business data is generated for each business in the period, written into the readable and readable time-series data storage means 11c, and time-series data from taxi exit to entry is collected and stored in the time-series data storage means 11c. The time series data collection device 1 for transmitting the time series data and the reception of the signal indicating the business / vacant state from the electronic taxi meter 6 determines the boarding place and the getting off place based on the position data indicating the current position. Each of the entry / exit data shown is generated, and this is written and collected in the readable / exitable entry / exit data storage means 25c, and a data request from the outside is obtained. Depending on getting on and off site data storage means 25c
And the time series data transmitted from the position data collection device 1 and the position data collection device 2 connected via the communication lines L1 and L2, respectively. It has a relay device 3 for receiving the getting on / off data. The relay device 3 sends the time series data received from the time series data collection device 1 and the getting on and off place data received from the position data collection device 2 to the read / write device 4 connected thereto, and reads / writes the data. The data is written on the recording medium 5 detachably attached to the writing device 4, and daily report data including time-series data including business data of each taxi business and getting on and off place data is collected.

In this taxi daily report data collection system, the business data of each taxi business to be collected as a part of the daily report data is written into the readable and readable time-series data storage means 11c in the time-series data collection device. The time series data is collected, and the getting on and off place data of each taxi business to be collected as another part of the daily report data is written and collected in the readable and readable getting on and off place data storage means 25c in the position data collecting device. Since the collected time-series data and the getting-in / out place data are received by the relay device 3, the position data read for each business is added to the business data for each business. It is no longer necessary to generate and collect daily report data, and data conversion processing and timing adjustment that must be performed when adding this data It is getting better even without the tedious process of such.

[0009]

As described above, in the proposed taxi daily report data collection system, the position data collection device 2 uses the electronic taxi meter 6 to change the level between a business state and an empty state. Is input, and it is known that the operating state and the empty state have been entered due to the change in the level of the input business / empty signal, and the boarding place and the getting-off place respectively indicating the boarding place and the getting-off place are indicated by the position data indicating the current position. The data is generated, and the data is written and collected in the readable and accessible landing data storage means 25c, and the landing data stored in the landing data storage means 25c is transmitted to the outside. . Specifically, for example, the position data collection device 2 determines that the vehicle has changed from empty to business in response to the rise of the business / empty signal from L to H level, and uses the position data at that time as the boarding place and It is determined that the vehicle has become empty from business in response to the fall of the empty signal from the H level to the L level, and the position data at that time is collected as a drop-off location.

For this reason, for example, when the ignition switch is turned to the starter position to start the engine, the battery power supply voltage temporarily drops suddenly. Disturbance occurs in the sales / empty signal received from the meter, and the position data collection device 2 determines that the position data has not been changed from empty to sales or from sales to empty, and the position data at that time is determined. And generates and collects the boarding place data indicating the boarding place or the getting-off place. Once such fictitious landing data is collected, the daily data is generated by adding the landing data to the sales data for each business in the time-series data collected by the time-series data collection device. In this case, there is a problem that the numbers of the sales data and the boarding / disembarking data in the time-series data do not match, so that desired daily report data cannot be generated.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and without increasing the total cost of the system, the data generated by the existing electronic taxi meter and the position data generated by the existing position data generating means can be obtained. It is an object of the present invention to provide a taxi daily report data collection system which can easily collect daily report data including boarding / disembarkation place data by combining the above.

[0012]

To the location data after receiving the warehousing data.
Daily data collection for receiving and getting on / off land data sent from the data collection device , writing the data on the recording medium 5, and collecting daily report data including the business data and the on / off land data in the time-series data. A business / empty signal whose level changes between a business state and an empty state is input from the device 3 and the electronic taxi meter, and a state change signal having a level corresponding to the level of the input business / empty signal is collected as the position data collection. State change detecting means 31a-1 which outputs to the device to notify that it has entered the business state and the empty state, and power cutoff detecting means 34-1 which detects that the supply of the battery power has been cut off.
And when the power cut-off detecting means detects that the supply of the battery power is cut off, the state change detecting means is operated / empty.
The present invention is characterized in that a change in the level of the vehicle signal is ignored, and a state change signal having a level corresponding to the level of the business / empty signal immediately before the detection of the interruption of the battery power supply is continuously output.

In the above-mentioned taxi daily report data collection system, the state change detecting means 31a-1 inputs from the electronic taxi meter 6 a business / empty signal whose level changes between a business state and an empty state, and inputs the input business / empty signal. A state change signal having a level corresponding to the signal level is output to the position data collection device 2 to notify that the vehicle is in the business state or the empty state.
When -1 detects that the supply of the battery power is cut off, a state change signal of a level corresponding to the level of the business / empty signal is not output. Even if the level is disturbed,
The position data collection device 2 does not generate imaginary boarding / alighting landing data due to the state change signal corresponding to the empty vehicle signal.

The taxi daily report data collection system detects that the battery power has been restored, and sends a signal having a level corresponding to the level of the business / empty signal input to the state change detection means to the position data collection device. And a power return detection means 34-2 for outputting the output.

When the power is restored, the power restoration detecting means 34-2 causes the state change detecting means to output a signal having a level corresponding to the level of the business / empty signal at that time to the position data collecting device. Position data collection device 2
Can generate normal getting on / off data.

When outputting a signal having a level corresponding to the level of the business / empty signal input by the state change detecting means to the position data collecting device, chattering processing means for ignoring chattering of the input business / empty signal. 31a
-2.

Since the chattering processing means 31a-2 ignores the chattering of the commercial / empty signal input, even if the commercial / empty signal is chattered when the power is restored, the state change signal is not changed. Generation of fictitious landing data can be prevented.

The position data collecting device 2 has a level corresponding to the level at which the daily report data collecting device 3 inputs a business / empty signal from the electronic taxi meter 6 and processes and outputs the input business / empty signal. When the state change signal is received, it is determined that the vehicle is in the business state or the empty state based on the level of the received state change signal, and the position data indicating the current position is generated as the boarding and dismounting place data indicating the boarding place and the getting off place, respectively. Then, this is written into a writable / readable internal memory (RAM) and collected. Further, when receiving the data request signal from the daily report data collecting device 3, the position data collecting device 2 outputs the getting on and off place data collected in the internal memory (RAM) to the daily report data collecting device 3, and outputs the daily report data. When a memory clear signal is received from the collection device 3, the boarding / alighting data of a predetermined area is cleared.

The daily report data collection device 3 sends the delivery flag as it is to the R / W device 4 in response to the input of the delivery flag from the time-series data collection device 1, and a flag called a delivery flag in a predetermined area in the internal memory. Stand up. this is,
Before writing the position data, this flag is used to determine whether to output a memory clear signal to the position data collection device 2 based on the state of this flag.

When the incoming data is input from the time-series data collection device 1, the data 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.

This is for inputting to the COM 31.

The power-off / recovery detection circuit 34 detects that the power supplied from the battery power supply has been cut off, and inputs a detection signal to the μCOM 31. The above-described time-series data collection device 1, position data collection device 2, and daily report data collection device 3 include a backup power supply (not shown) so that their μCOM can operate for a certain period of time even when the battery power supply is cut off. ing.

The CPU 31a of the μCOM 31 is a ROM 31
b operates according to the control program stored in
When the retrieval data is received from the time-series data collection device 1 via the 2b, the data is directly transmitted to the R / W device 4 via the selector 33a and the IF 32c.
A flag (delivery flag) is set in a predetermined area inside. 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 set and the retrieval flag is set, this determination is not performed until the position data writing is completed in order to shorten the relay processing time. Also,
When receiving the incoming data from the time-series data collection device 1 via the IF 32b, the CPU 31a converts the received data into a selector 33.
a, and transmits it to the R / W device 4 as it is via the IF 32c. However, when the termination command is received thereafter, it does not transmit this to the R / W device 4, but transmits its normal termination to the time-series data collection device 1. Then, the process starts writing the position data.

As described above, at the time of receiving the termination after receiving the warehousing 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 via the selector 33a and the RS232CIF 32d to receive the position data.
After switching a, the R / W device 4 is accessed and written to 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.

Further, the CPU 31a monitors the level of the business / empty signal input via the IF 32a, and when the level of the business / empty signal changes, performs a chattering process on the business / empty signal that fluctuates by operating the tariff switch. A signal having a level corresponding to the level of the business / empty signal detected as a result of the chattering process is output to the position data collection device 2 via the IF 32e as a state change signal. The CPU 31a also monitors the output of the power-off / return detection circuit 34 by means of a timer interrupt, and inputs the output via the IF 32a when the power-off / return detection circuit 34 receives the output when detecting the shutdown of the battery power. Ignore any change in the level of the sales / vacant signal and ignore it.
The state change signal output via F32e is held at the previous level. The CPU 31a further monitors the output of the power-off / return detection circuit 34 by a timer interrupt,
When the return of the battery power is detected, the level of the commercial / empty signal input via the IF 32a is monitored, and when the level of the commercial / empty signal changes, the chattering process is performed on the commercial / empty signal that fluctuates from the power return input. When the level of the business / empty signal detected as a result of the chattering processing is not the same as the state currently recognized, a state change signal of a level corresponding to the level is output to the IF.
The data is output to the position data collection device 2 via the communication device 32e.

Therefore, even if the level of the business / empty signal is disturbed due to the power cut-off, the position data collecting device 2 does not generate imaginary boarding / disembarkation data by the state change signal corresponding to the business / empty signal.

When the power is restored, if the signal of the level corresponding to the level of the business / vacant signal at that time has changed from that before, the level change signal is sent to the position data collecting device. Since the data is output, the position data collection device 2 can generate normal getting on and off data.

Further, since the chattering of the business / empty signal is ignored, even if the business / empty signal is chattered when the power is restored, the state change signal is not changed by the chattering. Can be prevented.

The details of the operation of the daily report data collection device 3 described briefly above are described in the CPU 31 incorporated in the μCOM 31.
This will be described below with reference to the flowchart of FIG. 9 showing the processing performed by a according to the control program.

The CPU 31a starts operation when the power is turned on. In the first step S31 shown in FIG. 9A, the CPU 31a performs communication processing such as reception of command data from the time-series data collection device 1, and then proceeds to step S32. Proceed to I
A business / empty signal is input via F32a, and in the next step S33, it is determined whether or not the level of the business / empty signal has changed according to whether or not the level of the input business / empty signal has changed from the previously input level. If the determination in step S33 is NO, the process returns to step S31. If the determination in step S33 is YES, that is, if it is determined that the level of the business / empty signal input via the IF 32a has changed, the flow proceeds to step S34 to perform chattering processing, and then to step S35. In step S35, the level of the business / empty signal is detected, a state change signal having a level corresponding to the detected level is output to the position data collection device 2 via the IF 32e, and the process returns to step S31.

In the process of performing the above-described steps S31 to S35, FIG.
In the first step S36, the output of the power-off / return detection circuit 34 is monitored, and it is determined whether or not power-off has occurred based on the output. When the determination in step S36 is NO and the power-off / recovery detection circuit 34 does not detect the power-off based on the output of FIG.
Return to the original step of (a). If the determination in step S36 is YES and the power cut-off is detected by the output of the power cut-off / return detection circuit 34, the process proceeds to step S37, where the output of the power cut-off / return detection circuit 34 is continuously monitored, and the power is restored by this output. When it is determined, the process proceeds to step S38.

In step S38, the IF 32a
Input a sales / vacant signal via the following step S39.
In step S, it is determined whether or not the level of the business / empty signal has changed based on whether or not the level of the input business / empty signal has changed from the previously input level.
When the determination at 39 is NO, the process returns to step S31. When the determination in step S39 is YES in the determination of YE, that is, when it is determined that the level of the business / empty signal input via the IF 32a has changed, the process proceeds to step S39.
Proceeding to 39a, a chattering process is performed. Thereafter, the process proceeds to step S39b, where it is determined whether or not the change in the level of the business / empty signal determined in step S39 is the same as the status currently being output to the current position data collection device 2 that is being recognized. I do. When the determination in step S39b is YES, the process returns to step S31, and when the determination is NO, the process proceeds to step S35 and the
A state change signal of a level corresponding to the detection level of the empty vehicle signal is output to the position data collection device 2 via the IF 32e.

By the operation of the daily report data collection device 3 described above, the recording medium 5 composed of an IC memory card detachably mounted on the R / W device 4, as shown in FIG. The time-series data collected by the location data collection device 1 and the boarding / disembarking site data collected by the position data collection device 2 are separately collected and collected.

In the above-described embodiment, a commercial / vacant signal whose level changes between the commercial state and the empty state is input from the electronic taxi meter 6, and the state of the level corresponding to the level of the inputted commercial / vacant signal is inputted. A state change detecting means 31a-1 which outputs a change signal to the position data collecting device to notify that the vehicle is in the business state or the empty state is formed in the daily report data collecting device 3. It may be formed. However, with the configuration as in the embodiment, it becomes possible to cause μCOM of the daily report data collection device 3 to perform the function of the state change detection means 31a-1 by a program.

[0062]

As described above, according to the present invention, when it is detected that the supply of the battery power is cut off,
Since the state change signal of the level corresponding to the level of the business / empty signal is not output, even if the level of the business / empty signal is disturbed due to the power interruption, the state change signal corresponding to this business / empty signal is used. No longer generates fictitious loading / unloading site data, but when trying to generate daily report data by adding getting on / off site data to the sales data for each business in the time series data, the sales data in the time series data and the getting on / off site It can be prevented that the number of data does not match and the desired daily report data cannot be generated.

Further, when the battery power is restored after the power is turned off, a signal having a level corresponding to the level of the business / empty signal at that time is output, so that normal landing data can be generated at the time of power restoration. it can.

Further, since the chattering of the business / empty signal is ignored, even if the business / empty signal is chattered when the power is restored, the state change signal is not changed by this and the generation of the imaginary landing data is generated. Can be prevented.
