Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a taxi meter, and more particularly to a taxi meter capable of clearly knowing the total operation time thereof.
[0002]
[Prior art]
In the taxi industry, the tariff is revised about once every three years. At that time, the taxi meter is removed from the taxi vehicle, the internal tariff calculation process, the setting of the fare accumulating method is changed, or the parts are replaced, and the taxi vehicle is changed again. Installed and reused.
[0003]
After the taxi meter is removed, a general inspection of the function of the taxi meter is performed at this time, and if necessary, the portion is repaired or parts are replaced.
For example, fast-wearing parts such as a fluorescent display tube or a liquid crystal display element have a shorter life than the average life of a taxi meter (6 to 10 years). Inspections were made and if necessary, replaced or repaired.
[0004]
[Problems to be solved by the invention]
However, in the case of the above-mentioned parts that rapidly wear out, for example, in the case of parts such as the above-described display element, inspection must be performed depending on the visual inspection of an inspector in an inspection process. Inspection standards are inevitably ambiguous depending on the subject's subjectivity and the level of skill in inspection skills.
[0005]
Therefore, the adequacy and necessity of replacement or repair of parts such as the above-mentioned display element is not accurately determined, and it is not long after reattaching to a taxi and reusing it despite performing a corner inspection. There is a problem that a failure or an operation failure occurs.
[0006]
Therefore, for the replacement or repair of taxi meter parts whose wear is relatively intense and whose accurate inspection is difficult, whether or not the average life of the parts has been reached is determined. A method has been devised for checking by referring to the history of the taxi meter from the time of manufacture.
[0007]
However, even if one attempts to replace a relatively heavily worn component with such a method in the above-described manner, the correlation between the degree of wear of the component and the average aging life of the component is actually increased. A considerable shift has occurred.
For example, despite parts that should not have reached the average life, they are actually worn out so that they can hardly be used practically. The inconvenience such that the component malfunctions has occurred.
[0008]
As described above, in the conventional inspection method, the inspection is performed when the taxi meter is removed, and in spite of the fact that the parts with high consumption can be repaired or replaced, the actual parts of the parts are actually removed. However, it is difficult to carry out a valid and accurate inspection of the above, so that an opportunity for replacement or repair is forgotten, or conversely, a part which is still usable is replaced. Further, there is a problem that a proper replacement time cannot be grasped even if a continuous use period from the time of manufacture and shipment is used as a parameter. Moreover, as a practical matter, it goes without saying that not all the consumable parts can be replaced when the taxi meter is removed.
[0009]
As a result, when the taxi meter is re-installed in a taxi despite the fact that the taxi meter and the inspection have been performed, there is a problem that a failure or malfunction occurs soon.
The present invention has been made to solve such a problem. The present invention accurately grasps, with high validity, the determination of the replacement time and the like of the replacement or repair of taxi meter parts, such as display elements, which are relatively intense and difficult to accurately inspect. The task is to provide a taxi meter that can be used.
[0010]
[Means for Solving the Problems]
First, the taxi meter of the present invention is mounted on a taxi vehicle (not shown, the same applies hereinafter), can be activated and deactivated according to the operation of the taxi vehicle, calculate taxi fare data and calculate taxi fare. A taxi meter that performs at least one of the displays, outputs operation time accumulation means 101 that accumulates the operation time of the taxi meter that has been operated while being mounted on the taxi vehicle, and outputs cumulative data of the operation time. Output means 200, and detachment detecting means for detecting when the taxi meter is detached from the taxi vehicle, wherein the output means is in a state in which the detachment detecting means is detached. Is detected, the accumulated data is output .
[0011]
That is, in the case of parts which have been relatively consumed (or fast) in the past, the aging of the taxi meter, such as a display element such as a fluorescent display tube or a liquid crystal display panel, is taken as a substitute for the use time of the part. By comparing this with the average life of the part, the validity of replacement or the like was determined.
[0012]
However, with such a conventional method, it is difficult to grasp the true degree of wear of the parts that need to be considered for replacement. The reason for this is that, for example, the degree of wear of such a highly consumable component differs greatly depending on whether or not the taxi meter is turned on and the operating voltage is applied.
[0013]
In addition, the use environment of passenger cars such as taxi vehicles is generally extremely harsh, and taxi vehicles equipped with such taxi meters are often placed in environments where they are used under, for example, hot summer weather or extremely cold winter. The components inside the car depend heavily on the condition (environment) of the taxi meter, such as whether it is open or in a garage-like place where it is protected from the elements. Also greatly changes the life.
[0014]
Therefore, in the taxi meter according to the present invention, the operating state of the taxi meter, which has a great effect on shortening the life of components inside the taxi meter, that is, whether the taxi meter is operating or stopped, is detected, By accumulating only the time during which the meter is operated by the operation time accumulating means 101, the accumulated operation time is used as a parameter for measuring the substantial life of the highly worn parts used inside the taxi meter. Can be used.
As a result, it is possible to measure the substantial life (the degree of wear at the present time) of the parts that are heavily worn, and it is possible to accurately grasp the appropriate time for parts replacement and the like.
Also, a taxi meter is typically inspected and repaired when it is removed from a taxi. Therefore, according to the present invention, when the taxi meter is removed from the taxi vehicle, the accumulated operating time data that has been accumulated and stored can be automatically output on the display device 201 or the like, and can be used for inspection and repair. When it is necessary to review the actual operation time, it is possible to confirm the cumulative total of the actual operation time, which is a highly valid judgment material for the study.
[0015]
Also, taxi meter of the present invention, the second is mounted on a taxi vehicle, the taxi operation and its stop in response to operation of the vehicle is possible, at least one of the operation and the taxi fare display taxi data In a taxi meter that performs one of them, an operation state detecting means 102 for detecting an operation state of the taxi meter, and when the operation start of the taxi meter is detected by the operation state detection means 102, the operation time of the taxi meter is reduced. The measurement is started, and when the operation stop of the taxi meter is detected by the operation state detecting means 102, the measurement is stopped, and the operation time of the taxi meter from the start of the operation to the stop of the operation is measured. Operating time measuring means 103; storage means 104 for storing the measured operating time; When the stoppage is detected and the operation time is measured, the operation time stored in the storage means 104 before the measurement is read out, and the operation time is added to the operation time to obtain the operation time. The operation time accumulation means 101 for storing the accumulated operation time in the storage means, the output means 200 for outputting the accumulated operation time, and the state where the taxi meter is removed from the taxi vehicle. And removal detection means for detecting when the removal has occurred, wherein the output means outputs the cumulative data of the operation time when the removal detection means detects the detached state. And
[0016]
Such a configuration of the main part is particularly suitable for a taxi meter using an electronic circuit such as a microcomputer (hereinafter abbreviated as a microcomputer) inside. That is, since taxi meters using microcomputers or electronic circuits have become almost mainstream in recent years, the present invention employs the above-described main configuration to perform ordinary taxi fare calculation and display data processing, etc. It is not necessary to add a complicated circuit system to the taxi meter performed in the above, and the present invention can be easily applied.
[0017]
Thirdly, in the taxi meter according to the first or second aspect, the taxi meter has a display device 201 for displaying a taxi fare, and the output means is the display device. The display device displays the cumulative data of the operation time when the detachment detecting means detects the detached state.
[0018]
That is, the operation time from the start to the stop of the operation is measured as one interval for each operation stop, and data obtained by accumulating the measured operation times for each interval is displayed on a taxi meter display device 201 for displaying, for example, a toll fee. , And the display device 201 displays the total operation time. As a result, it is possible to confirm the actual cumulative operation time since the taxi meter was mounted.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the taxi meter of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a main part of a taxi meter according to the present invention. FIG. 5 is also used as a display device 201 for displaying a taxi fare and the like and the total operating time, and also as an operation device 300 for operating the output device 200 while being used as a switch for switching various normal tariffs. FIG. 3 is a diagram showing an outline of a front panel 400 portion of a taxi meter according to the present invention, in which various tariff buttons 301 (301a, 301b, 301c... 301g) are provided.
[0024]
The taxi meter is mounted on a taxi vehicle and can be operated and stopped in accordance with the operation of the taxi vehicle. The taxi meter calculates a taxi fare data and displays the taxi fare. The arithmetic processing circuit functions as a normal taxi meter. A microcomputer (not shown) for constructing a substantial circuit of each part including the system is provided.
[0025]
The taxi meter according to the present invention further includes an operating state detecting unit 102, an operating time measuring unit 103, a storage unit 104, and a detachment detecting unit 105. Further, an output unit 200 and an operation unit 300 are provided.
As for the output means 200, a display device 201 for displaying a taxi fare and the like and displaying the total operating time is also used as the output means 200. The operation means 300 includes an actual vehicle (rental) tariff 301a, a high-speed tariff, which is used as a switch for switching a different processing function for each tariff such as a real taxi meter (real vehicle), high speed, payment, pick-up vehicle, etc. Normal tariff buttons 301 such as 301b, payment tariff 301c, pick-up tariff 301d, etc. are also used as the operation means 300.
[0026]
The operating state detecting means 102 detects the operating state of the taxi meter. That is, when the operating state detecting means 102 detects the start of operation of the taxi meter, the operating time measuring means 103 starts measuring the operating time. When the operation state detecting means 102 detects the stop of the operation of the taxi meter, the operation time measuring means 103 stops the measurement of the operation time and calculates the operation time of the taxi meter from the start of the operation to the stop of the operation. I do. This calculation can be realized, for example, by calculating the difference between the time measurement data (time data) at the time of operation stop and the time measurement data (time data) at the time of operation start.
[0027]
The storage unit 104 stores the accumulated operation time data.
The operating time accumulating means 101 accumulates the operating time data calculated and measured by the operating time measuring means 103 as described above every time the operation of the taxi meter is stopped.
That is, when the operation stop is detected and the operation time is measured, the operation time accumulation means 101 is constructed by using, for example, a microcomputer, the accumulated operation time data stored in the storage means 104 before the measurement. If so, the operation time is accumulated by adding the measured operation time data to the read-out cumulative operation time data. Then, the accumulated operation time data is stored in the storage means 104.
[0028]
The output means 200 outputs the operation time data thus accumulated to a display device 201 such as a liquid crystal display panel.
Furthermore, a tariff button 301 (actual car tariff 301a, high-speed tariff 301b, payment tariff 301c, pick-up tariff) provided on the front panel 400 of the taxi meter for switching the taxi fare calculation processing and the display of the taxi meter. 301d, wireless waiting tariff 301e, cumulative total 301f, empty car tariff 301g, etc.) are also used as operating means 300 for performing an operation of causing the output means 200 to execute output, and the tariff button 301 is a predetermined procedure. Is configured to execute the above-described output when operated. For example, a setting is usually made such that an execution instruction for output is input when the empty car tariff 301g and the rental tariff button 301b among the tariff buttons provided on the front panel 400 of the taxi meter are simultaneously pressed. Needless to say, it is preferable to set so that the display output command is input by an operation different from the tariff switching operation.
[0029]
The taxi meter has a display device 201 such as a liquid crystal display panel for displaying a normal taxi fare. The output device 200 outputs the total of the operation time by the display device 201. .
Further, the taxi meter includes a detachment detection means 105 for detecting when the taxi meter is detached from the taxi vehicle. When the detachment detecting means 105 detects the detached state, the output means 200 outputs the total data. This removal detecting means 105 detects when the power supply voltage supplied from a power supply system such as a lead storage battery attached to a taxi vehicle becomes zero. That is, when the taxi meter is removed from the taxi vehicle, the taxi meter is usually once disconnected from the power supply system. Therefore, by detecting that the power supply voltage has become 0, it is possible to detect that the taxi meter has been removed.
[0030]
In the above-mentioned schematic configuration, the operating time accumulating means 101, the operating state detecting means 102, the operating time measuring means 103, the storage means 104, and the removal detecting means 105 are provided inside the taxi meter, and are used to determine the traveling distance and time. Needless to say, a microcomputer system that calculates a taxi fare in response may be used.
[0031]
In this case, the storage unit 104 may use a RAM or the like built in the microcomputer, or may use an EEPROM or the like attached as a peripheral device outside the microcomputer. Further, even when the taxi meter is removed from the taxi vehicle and the power supply voltage (VDD) is not supplied at the time of a fee revision or a periodic inspection, etc., the operating time accumulated data stored in the storage means 104 is not volatilized. Must be retained. Therefore, it is preferable to use a nonvolatile memory element as the storage unit 104. Alternatively, when a volatile memory element is used, it is needless to say that the memory (data) needs to be held by providing a backup power supply or the like inside the taxi meter.
[0032]
In addition, as the output means 200, in addition to the above-described display device 201 using a display element such as a liquid crystal display panel or a fluorescent display tube, a taxi meter is usually attached, and the taxi meter performs arithmetic processing. A printer or the like that prints out the taxi fare on a receipt paper sheet or a taxi ticket voucher can be suitably used.
[0033]
FIG. 2 to FIG. 4 are schematic flowcharts showing the outline of a program for causing the main components of the present invention to function.
When the taxi meter according to the present invention is manufactured in a factory and mounted on a taxi vehicle for the first time and connected to a power source, its function starts to operate. At this time, the taxi meter is stored in an EEPROM or the like used as the storage means 104 described above. The data is read (s1), and it is checked whether or not the data of the check code exists therein (s2).
[0034]
Normally, such a check code is not stored in advance at the time of shipment (N in s2), and in the case of such initial installation, the check code is stored (recorded) in the EEPROM or the like (s3). ). Then, a storage area for storing the total operation time of the storage unit 104 is initialized (s4).
[0035]
After the taxi meter is removed for periodic inspection, etc., the next time the taxi meter is remounted, since the check code has already been given, the steps s1 to s4 are omitted, and the taxi meter is substantially omitted. Starts from the next s5.
Alternatively, regarding the procedure for initializing the storage area of the storage means 104 such as s1 to s4, before the taxi meter is manufactured and shipped (for example, at the time of shipping inspection or the like), the factory side initializes the taxi meter in advance. You may make it. In this case, the taxi meter does not need to perform the initialization such as s1 to s4, which can further contribute to simplification of the program and the circuit structure.
[0036]
Subsequently, during the ACC-OFF (N in s5), the measurement is not started and the ACC-ON is awaited. However, if the taxi vehicle equipped with the taxi meter according to the present invention is turned on ACC-ON using the key of the taxi vehicle to start business (Y in s5), the electric system and engine of the taxi vehicle operate. At the same time, the operation time measurement (time measurement) is started to continued (s6). The measurement of the operation time is continued as long as ACC-ON is performed until the next ACC-OFF (N in s7), and stops when the ACC-OFF is performed (Y in s7) (s8).
[0037]
Then, the operation time data measured (timed) up to the time when the operation is stopped is temporarily read into a work area for performing arithmetic processing (s9). Then, the operation time total is calculated (s10). The operation time total calculation processing is shown in the schematic flowchart of FIG. 3 as the operation time total subroutine s10.
[0038]
After the ACC-OFF is performed as described above and the measurement (time measurement) of the operation time is stopped, if the accumulated data of the operation time measured before the current measurement is stored in the storage unit 104 (Y in s11) ), The stored data is read out from the storage means 104 (s12), and is once read into the same work area as above (s13). However, if there is no stored data in the storage unit 104 (N in s11), the operation time data measured this time is recorded in the storage unit 104 (s14).
[0039]
Subsequently, the cumulative data of the operating time up to the previous time once read into the work area is added to the operating time data measured this time (s15). Then, the accumulated data is written to the storage means 104 as the latest operation time accumulated data at that time (s16).
[0040]
After that, when the power supply voltage becomes 0 and it is detected that the taxi meter has been removed (Y in s17), the power supply voltage is intermittently accumulated every time the ACC is turned on / off during the period up to that time and stored in the storage means 104. The accumulated operation time data is output (s20). Alternatively, even in cases other than the above, when an output command (for example, simultaneously pressing the empty vehicle tariff 301g and the actual vehicle tariff 301a as described above) is operated according to the operation procedure predetermined as described above (step S18). Y), and outputs the accumulated operation time data stored in the storage means 104 up to that point (s20). The procedure for outputting the accumulated operation time data is shown in the outline flowchart of FIG. 4 as the operation time output subroutine s20.
[0041]
However, if the operation of instructing the execution of the output is not performed (N in s18), the state returns to the ACC-ON waiting state again (s5).
When the taxi meter is removed as described above (Y in s17) or when an operation for instructing output is performed (Y in s18), the stored data stored in the storage unit 104 at that time, that is, The operation time total data up to the time is read (s21). Then, the display device 201 displays the total operation time based on the data (s22).
[0042]
After outputting the cumulative operation time, the taxi meter is mounted on the taxi vehicle again, and performs the cumulative operation time in the same procedure as described above (N in s23).
If it is desired to select a new operation time accumulation starting from the time of re-installation (Y in s23), before the taxi meter is re-installed in the taxi vehicle, it is stored in the EEPROM or the like. What is necessary is just to delete the stored check code (s24).
[0043]
Here, in a program having the above procedure in its main part, the operating time measuring means 103 according to the present invention is s1 to s9, the operating time accumulating means 101 is s10 (s11 to s18), and the operating state is The detection means 102 is executed in s5 and s7, the removal detection means 105 is executed in s17, and the output means 200 is executed in s20 (s21 to s24).
[0044]
【The invention's effect】
As described in the detailed description above, according to the present invention, first, only the time during which the taximeter is substantially operating is accumulated by the operating time accumulating means 101, so that this accumulation is performed. The operating time can be used as a parameter to measure the substantial life of the highly worn parts used inside the taxi meter.
In addition, when the taxi meter is removed from the taxi vehicle, the accumulated operating time data that has been accumulated and stored can be automatically output on the display device 201 or the like, and the validity of inspection and repair is high. When the examination is necessary, it is possible to confirm the accumulated actual operating time, which is a criterion for the examination.
[0045]
Second, the present invention is particularly suitable for the construction of a taxi meter using an electronic circuit such as a microcomputer inside. That is, since taxi meters using microcomputers or electronic circuits have become almost mainstream in recent years, the present invention employs the above-described main configuration to perform ordinary taxi fare calculation and display data processing, etc. It is not necessary to add a complicated circuit system to the taxi meter performed in the above, and the present invention can be easily applied.
[0046]
Thirdly, according to the present invention, the operation time from the start to the stop of the operation is measured as one interval for each operation stop, and the data obtained by accumulating the measured one-interval operation time one by one is, for example, a toll fee or the like. The output is outputted to the display device 201 of the taxi meter to be displayed, and the total operation time is displayed on the display device 201. As a result, it is possible to confirm the cumulative operation time since the taxi meter was mounted.
