Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a taxi sales information recording device which is electrically connected in a fixed manner to a taximeter, has a recording section detachably attached thereto, and has a built-in central processing section, storage means, and clock means. (hereinafter abbreviated as sales information recording device).

Generally, taxis are equipped with a taxi meter to keep track of business information. This business information includes total mileage, business mileage, number of business trips, subsequent number of trips, idling distance, etc. Some of this is for billing customers, and some is for billing customers. It is used by taxi companies or offices to understand the operating status of taxis, and is displayed in some form on the taxi meter. There are two main types of taximeters: That is, one is to display the cumulative value of each business information with an electromagnetic counter, and the other is to cumulatively store each information in IC memory,
It is an electronic type that visually displays the contents on a display. However, in any case, these taximeters are fixed to the vehicle, and therefore, in most cases, when the displayed information is aggregated or otherwise processed by the taxi company or other departments of the sales office,
It was necessary to manually transcribe the contents onto a slip or the like in advance. Conventionally, for example, Japanese Patent Application Publication No. 1983
As shown in Japanese Patent Publication No. 46178 and Japanese Patent Publication No. 58-42493, only some electronic taximeters are equipped with a connection circuit for transferring the contents of the built-in IC memory, and the contents cannot be transferred via the recording control unit. There are some taximeters that can transfer records to a recording section outside the taximeter, but all of these are limited to electronic taximeters, and it is impossible to record the contents unless they are equipped with an external transfer function. Ta. In addition, in the case of electronic taximeters, the taximeter itself is generally equipped with such a function, and the recording control unit does not have a built-in storage means or clock means, so it simply passes through the taximeter information. However, when it becomes necessary to add some new business information, the function of the taximeter itself has to be changed. Changing the taximeter itself, even for a short period of time, would not only cause losses due to the suspension of commercial vehicles, but would also be subject to legal restrictions as it deals with fares.
This caused various problems.

This invention was made in view of the above-mentioned conventional circumstances, and allows business information handled by a taximeter to be automatically (electrically) transferred and recorded outside the taximeter, and is not fixed to the vehicle. Sales information that makes it possible to easily obtain newly required sales information without having to change the function of the taximeter itself, which is quite troublesome as it is subject to legal regulations. The purpose is to provide a recording device.

Specifically, it can be electrically connected to a taximeter whose calculation unit calculates and obtains a count signal based on a status signal related to the business status given by the tariff and a distance signal obtained from a distance sensor. It is a business information recording device that is said to be a business information recording device, and consists of a main device that can be electrically connected to a taximeter, and a recording section that can be attached to and detached from the main device. a first memory circuit for storing information;
a central processing unit that processes the status signal and count signal given from the taximeter into sales information according to a program stored in a first storage circuit; and a central processing unit that stores the sales information created by the central processing unit. and a second memory circuit for storing the data, and the recording unit stores the second data according to the instructions from the central processing unit and the program stored in the first memory circuit.
Provided is a sales information recording device comprising a third storage circuit for storing sales information transferred from the storage circuit, and the main device further comprises a clock circuit for generating a clock signal and creating time data. We provide a sales information recording device that includes:

According to such a business information recording device, business information handled by a taximeter can be easily and automatically (electrically) transferred and recorded outside the taximeter. That is, this business information recording device sequentially processes the status signal and count signal obtained from the taximeter to create business information, and temporarily stores this business information in the second storage circuit within the main device. In order to transfer and record business information externally, the business information stored in the second memory circuit can be attached to and detached from the main unit, and is convenient for carrying as it only has a memory circuit. Since the business information is transferred to the taximeter section and transferred and recorded to an external device via this recording section, it is possible to easily transfer and record the business information handled by the taximeter to the outside.

Furthermore, according to such a sales information recording device,
Newly required business information can be easily obtained without changing the function of the taximeter itself. That is, by simply changing the program stored in the first memory circuit in the main device, a new range of business information that can be created by processing the status signal and counting signal obtained from the taximeter can be obtained. It's easy to do.

In order to create such new business information, it is more advantageous if the main unit is provided with a clock circuit that generates a clock signal and creates time data.

An embodiment of the present invention will be described in detail below with reference to the drawings.

As shown in a perspective view in FIG.
The device main body 2 is electrically connected to an existing taximeter 6 via a connector 5 via a cable 4. When the recording unit 3 is inserted into the insertion port 7 of the device main body 2, it is mechanically held and electrically connected to a predetermined circuit inside the device main body, but when the recording unit 3 is inserted normally, a buzzer sounds as described later. The sound will sound for a short period of time, and the indicator lamp 8 will continue to light up to provide confirmation to the crew. The recording section 3 is also easy to pull out, that is, it is detachable, and when it is pulled out, the indicator lamp 8 turns off.

FIG. 2 is a block diagram showing the circuit configuration of the business information recording device 1 connected to the taximeter 6. As shown in FIG. Distance sensor 10 of taximeter 6
generates a single pulse distance signal t ₁ every time the vehicle travels 1 m, and outputs it to the calculation unit 11 . The rotary switch-type tariff 12 maintains the rotational position set by the crew member, and while it is set, the output line corresponding to the set position is set to indicate ``pay run'', ``20% increase'', and ``pick up''. , outputs a status signal t2 indicating one of the four statuses of "payment", and outputs a status signal _t2 indicating one of the four statuses of "payment",
1. In addition, the tariff 12 is provided with a status position of "vacant vehicle", and when set to "vacant vehicle", the status signal _t2 is not output. Furthermore, when none of the four types of status signals described above are present, the vehicle is considered to be in an "empty" state. The calculation unit 11 determines the current state based on the state signal _t2 from the tariff 12, calculates the distance signal _t1 corresponding to each state, and outputs the result as a count signal _t3 to the taximeter 6. The information is sent to each electromagnetic counter type display 13 (not shown), and the corresponding electromagnetic counter is incremented to display the idling distance, travel distance, riding distance, number of rides, subsequent number of rides, or fare. The status signal _t2 and the count signal _t3 are also sent to the external connection circuit 14, where they are converted into a serial signal _t4 according to the time sequence as shown in FIG. 4, and sent to the sales information recording device 2. Sent. The serial signal _t4 in FIG. 4 shows one embodiment and may be in other forms or may be a parallel signal. The present invention can be easily implemented by modifying the input section of the business information recording device 1 in accordance with each signal format. Further, the taximeter 6 shown here is only one example of implementing the present invention, and the present invention can of course be applied to other taximeters as long as the status signal _t2 and count signal _t3 can be obtained. The serial signal t4 in this embodiment shown in FIG. ₄ is allocated 160 μs and is sent out repeatedly every 160 μs. This serial signal t ₄ is further divided into 16 equal parts to have a 16-bit configuration, and the count signal t ₃ and the status signal t ₂ are sent every 10 μs from the left to the right in the figure, first, the number of rides,
Next, a count signal indicating the subsequent number of times... pick-up, then a status signal indicating payment, etc. are expressed in binary according to the time sequence in the order. The status signal _t2 indicates each status depending on the set position of the tariff 12 as described above, but in the serial signal _t4 , the status is expressed in binary values at the time of each assignment. That is, if the tariff 12 is set to pay running, 90 μs from the beginning in the serial signal _t4 shown in the figure.
and 100 μs, the serial signal _t4 is “1” among the two values.
The time points assigned to the other three types of state signals are all binary "0" states.
The same goes for the count signal _t3 , if there is a signal that updates the electromagnetic counter that displays the number of rides every 160 μs, it will be binary for the first 10 μs,
It will be in the "1" state, but if it is not there, it will be in the "0" state. Blank areas in the figure are unused, and the corresponding bits are always set to "0".

The device main body 2 in FIG. 2 includes an input circuit ₂₀ that receives a serial signal t4 from a taximeter 6, a central processing section 21 including an 8-bit microprocessor, control of each circuit, information transmission and reception, calculation, processing, and new processing. A ROM (read-only memory) 23 serves as a first memory circuit that stores a processing program for generating and storing information, and a second memory circuit serves as a storage location for processed information.
A memory circuit 22 consisting of a RAM (random access memory) 24, an input/output circuit 25 that sends and receives information to and from the recording section 3, a clock circuit 26, a switch input circuit 27, a display driver circuit 28, a switch section 29,
It consists of a lamp buzzer section 30, a three-terminal regulator 31, etc. 32 is a data bus for exchanging information, 33 is an address bus for transmitting an instruction of the location where information is to be exchanged, D is a diode, and _C1 is a large capacitor. Power for the device main body 2 is supplied from a 12V battery mounted on the vehicle via a taximeter 6 together with a ground. A diode D is inserted in series with this power supply, and the aforementioned capacitor _C1 is inserted in parallel with the power supply on its output side, and the other end is grounded. Even if the power to the device body 2 is turned off due to removal of the engine key or other reasons, the clock circuit ₂
6 continues to operate, and the contents stored in the RAM 24 are also continuously saved without being erased. This backup function guarantees at least two weeks without power.

Control of each circuit, information transmission/reception, calculation, processing, etc. in the business information recording device 1 of the present invention are all performed by commands from the central processing section 21 and by instructions from the storage circuit 22.
Although this is performed by a program stored in advance in the ROM 23, each description will be omitted in the following explanation.

The device main body 2 is in the operating state (recording section 3 is in the device main body 2)
is installed (roughly between the time of leaving the parking lot and the time of returning to the parking lot), the device body 2 receives the aforementioned serial signal _t4 from the taximeter 6 into the input circuit 20. Divide this into 2
data bus 32.
The data is transferred to the central processing unit 21 via. The central processing unit 21 analyzes the data from these two 8-bit signals to detect the state of the tariff 12 at that time, and calculates the remaining data using the state signal of the tariff 12 and the time data from the clock circuit 26 as given conditions. In combination, the RAM 24 is used to count, process, and store the data. The clock circuit 26 not only generates a clock signal with a predetermined period (256 Hz), but also creates time data in units of hours, minutes, and seconds within the circuit, and transfers this to a predetermined location in the RAM 24 every second to store it. . FIG. 5 shows various types of information handled and stored in the apparatus main body 2 and recording section 3 of the present invention. The following describes the main information in FIG. 5 and the information that is new compared to the conventional information. When the device of the present invention is installed in a taxi, the control code determines whether or not the information that has been cumulatively displayed by the taximeter 6 has been previously transferred to the RAM 24 of the device main body 2. The vehicle code is a code unique to the vehicle in which the device main body 2 is installed, and this code must also be programmed into the RAM 24 before installation.
is memorized. The crew code is a code transcribed from the recording unit 3 when the recording unit 3 is inserted, as described later, and is a code unique to the crew member who owns the recording unit 3, as well as a code unique to the recording unit 3. . The vehicle code and crew code serve as keywords when the information transcribed in the recording unit 3 is transcribed into a company's host computer or the like and searched. The total travel distance in the information b this time is information unrelated to the set position of the tariff 12, and is based on the serial signal t ₄ given from the taximeter 6.
Each time the bit of the mileage signal (generated every 1km of the vehicle's mileage) is input as "1".
The count value at a predetermined location in the RAM 24 is counted and stored by incrementing it one count at a time. When the tariff 12 is set to a value other than empty, the bits indicating the distance traveled, the number of rides, and the number of subsequent rides in the serial signal _t4 are "1". If there is, the counted value of each piece of information is counted up by one count and stored. As for the number of pick-up times, when the tariff 12 is moved from an empty car to a pick-up car position, the corresponding bit in the serial signal _t4 is output as "1", but it is confirmed that this state continues for more than 30 seconds. After that, count and memorize only one count. The duration monitoring is to exclude cases where the tariff 12 is temporarily rotated beyond this position as it is of the rotary switch type. The idling distance is generated every 100m after traveling 2km while the Tariff 12 is traveling as a pick-up vehicle, and the serial signal t ₄
The idling distance bit in the middle is output as “1”, but
This is detected, counted, and stored. In addition, this current information b displays each piece of information as a cumulative value from the time the taximeter was installed on the vehicle, just as the odometer of a normal vehicle displays the cumulative value from the time the car was new until the time it was scrapped. We are planning to add it up. Also, the previous information a is, roughly speaking, the cumulative total of business information up to the previous day (correctly, the previous time).
Therefore, by subtracting the previous information a from the current information b, the current day's business information can be obtained. The above is business information that has been handled conventionally, but below we will explain what can be added according to the present invention. The total actual vehicle time C is the cumulative time for actually picking up passengers, including the time required for picking up vehicles, during one day's business, and is the cumulative amount of time when any of the status signals is "1".
Clock circuit 2
6 clock signal, count this and store it in RAM.
24. The total steering time d is calculated by subtracting the break time from the time from the leaving time to the returning time, which will be described later. There are two types of rest periods; one is when the vehicle is stopped with the engine running and Tariff 12 is set to be empty, and the vehicle is stopped for a rest; However, since the 1m pulse indicating that the vehicle is running is not input to the device main body 2, this is detected and the clock signal is used to take a break for the amount of time that exceeds a predetermined time period until the next time the vehicle runs and the 1m pulse is input. It is something that takes time. Another case is when the engine is stopped, in which case the power is turned off, so the central processing unit 21 and ROM 23 do not operate. Therefore, time data cannot be transferred from the clock circuit 26 to the RAM 24. But capacitor C ₁
Because of the backup function, the time immediately before the power was turned off is stored and retained in the RAM 24. Further, the clock function of the clock circuit 26 continues to keep time by timekeeping. Therefore, turn on the power, start the engine, start driving, and drive for the first 1 m.
When the pulse is input, the time stored in the RAM 24 and the time displayed by the clock circuit 26 are compared, and a predetermined time is subtracted from the difference to determine the rest time. Both of these break times are calculated each time the user takes a break, and are stored in a predetermined location in the RAM 24 as a cumulative value. As will be described later, the return time read from the clock circuit 26 based on the switch operation by the crew member when returning to the warehouse, and the RAM
By comparing and subtracting the leaving time stored in RAM 24 and further subtracting the cumulative break time from RAM 24, the total steering time d can be determined. This time d is also
It is stored in RAM24. Business information for each session is
This is business information for each business trip with a passenger on board, and stores the boarding time of the customer, the time of getting off the vehicle, and the number of subsequent trips for each business trip. n times a day
If you deal with customers, the amount of information will be n times, but the maximum amount of information will be about
It is possible to memorize 80 times, which is sufficient for the actual situation. The boarding time is the time when the tariff 12 moves from an empty car position to another position, the alighting time is the time when the tariff 12 returns from a position other than an empty car to an empty car position, and for business, the number of times after that.
Store in RAM24.

The recording unit 3 is a portable type that can be attached to and detached from the main body 2 of the apparatus, and as shown in FIG. 40. As a third memory circuit
It consists of a RAM 42 and an address register 41 that specifies an address for writing or reading information to this RAM 42. When the recording section 3 is attached to the apparatus main body 2, power and ground are supplied from a 12V battery via the apparatus main body 2 via connectors J ₁ and J ₂ . When the recording unit 3 is removed from the main body 2 and the battery power is turned off, the RAM 42
In order to preserve the memory contents inside, a relatively large-capacity capacitor C ₂ is inserted in parallel with the power supply and a diode D is inserted in series for backup of the power supply. Memory is guaranteed even in the above power-off state. The connection interface between the apparatus main body 2 and the recording section 3 is all designed to exchange signals with a photocoupler, except for the power supply mentioned above. RESET signal S ₁ ,
The INCR signal S ₂ , DO signal S ₃ , and W/R signal S ₅ are generated by converting control information from the central processing unit 21 of the device main body 2 from electrical signals to optical signals by the light emitting element at the input/output circuit 25. The input/output circuit 40 of the recording section 3 receives this optical signal using a light receiving element and restores it to an electrical signal. On the contrary, the DI signal S ₄ is provided with a light emitting element in the input/output circuit 40 of the recording section 3 and a light receiving element on the apparatus main body 2 side. The RESET signal _S1 is repeatedly input to the input/output circuit 25 in a short period, and the W/R signal
_S5 is used to control the direction of information transfer, and is normally set to a binary value of "0." However, as will be described later, when the crew returns to the warehouse, the information stored in the device main body 2 is transferred to the recording unit 3. When transferring data to , it becomes "1" in response to a switch operation. At the start of the day's work, the crew member first inserts the recording section 3 into the main body 2 of the device. At this time, if the connectors J ₁ and J ₂ are inserted correctly, power is supplied to the input/output circuit 40. The light receiving and light emitting elements in the circuit 40 become active. Then
The address register 41 is reset by the RESET signal _S1 , and the highest address of the RAM 42 is selected. If the previous (previous day's) information stored in the recording unit 3 has been processed at a business office, etc., and the recording unit 3 is usable, the contents of this address will be binary "1". Therefore, this signal passes through the input/output circuit 40 as the DI signal S ₄ to the input/output circuit 25.
The main body 2 of the apparatus recognizes the insertion of the recording section 3. As a result, the display driver circuit 28 is driven by a command from the central processing section 21, and the display lamp 8 in the lamp/buzzer section 30 lights up as described above, and the buzzer sounds for a predetermined period of time. When the insertion of the recording section 3 is confirmed, the input/output circuit 25 outputs the following RESET signal.
The transmission of S ₁ is suppressed and the INCR signal S ₂ is transmitted instead. This signal _S2 is the address register 4 of the recording section 3.
Count up 1 sequentially, and for each count
The information bit at the corresponding address in the RAM 42 is read onto the DI line and sent to the main body 2 of the device. And recording section 3
The crew code (see FIG. 5) that is fixedly stored is transferred to the device main body 2 and stored in the RAM 24. Next, the previous information a shown in FIG. 5 is cleared and the current information b is transferred thereto. Through this operation, current information b becomes new previous information a, but since current information b before transcription is not cleared, information with the same content is stored in two locations. When the business starts, each piece of information is added and accumulated on top of this current information b. At the same time as this posting, the daily business information is cleared, and the time of insertion of the recording section 3 is stored in the RAM 24 as the time of departure (see FIG. 5).

At the end of the day, when the crew member or operator presses the write instruction switch 9 shown in Fig. 1 (one of the switch parts 29 shown in Fig. 2), the time at the time of pressing is changed to the return time (Fig. 5). reference) is stored in the RAM 24. On the other hand, the RESET signal S ₁ that has been suppressed in the input/output circuit 25 is output to the input/output circuit 40 by pressing the write instruction switch 6 to reset the address register 41, and then the W/R signal S ₅ is output.
is set to "1" for a predetermined period of time. and DO signal S ₃
is output as a binary "1", and the "1" at the highest address of the RAM 42 is stored. Next, the address is counted up in the register 41 by the INCR signal _S2 , and the address is added to the RAM in the device main body 2 for each count.
All the information shown in FIG. During this writing, a predetermined lamp 8' in the lamp/buzzer section 30 lights up and the buzzer sounds, but when the writing is finished, the lights go out and the sound stops. These operations are also all executed by the central processing unit 21 and ROM 23 of the device main body 2. The recording section 3 that has been transcribed is extracted from the main body 2 of the apparatus by a crew member or operator and submitted to a predetermined department. The information is then transferred to the host computer and used for various aggregation and other purposes.

Since the business information recording device according to the present invention is as described above, it has the following effects.

(a) The status signal and count signal obtained from the taximeter are sequentially processed to generate business information, this business information is temporarily stored in a second storage circuit within the main device, and this business information is transferred to the outside.・For recording, the business information stored in the second memory circuit is transferred to the recording unit, which is detachable from the main unit and is convenient to carry as it only has a memory circuit. Since the business information is transferred and recorded to the external device via the recording section, the business information handled by the taximeter can be easily transferred and recorded to the outside.

(b) It is possible to process the status signal and count signal obtained from the taximeter by simply changing the program stored in the first memory circuit in the main unit, without changing the function of the taximeter itself. It is easy to obtain new sales information within the range that can be created.

(c) In particular, by providing the main unit with a clock circuit that generates a clock signal and creates time data, it is possible to expand the range of creation of new time-related business information.
