Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for recording operation data such as traveling speed, traveling distance, parking and stopping of a vehicle in a semiconductor memory formed in a card form.

<Conventional technology> As this kind of device, a case formed in a box shape
A data collection processing device containing an interface unit, an internal memory, an arithmetic processing unit, a clock unit, and a card writing / reading unit is connected to a vehicle speed measurement output shaft in a transmission, for example, so as to be proportional to the traveling speed of the vehicle. A vehicle speed sensor that outputs a pulse signal, a switch sensor that detects and outputs an on / off signal of an engine key switch, and a card type that is detachably inserted into and connected to the card writing / reading unit. A vehicle speed data sampled at a predetermined cycle through an interface unit based on a detection signal of the switch sensor and a pulse signal of the vehicle speed sensor, and arithmetically processing the data. The operating data including the travel distance and the parking / stopping time data is recorded on a memory card.

Then, on the front of the case of the data collection processing device,
A memory card insertion slot, a time display section, and a key input operation section are provided so that time can be set and corrected by inserting / removing the memory card and key input operation.

<Problems to be Solved by the Invention> However, in the above-described configuration, the setting and correction of the time required for collecting the operation data are read out from the clock unit on the time display unit provided on the front of the case. The current time is displayed and the key input operation is performed based on this display, so the driver can arbitrarily set and correct the time and easily change the operation data recorded on the memory card This makes it difficult for an operation manager who manages many vehicles to obtain accurate operation data necessary for management.

In order to improve this, it is conceivable to provide a means such as a seal and a key lock so that the key input operation can be operated only by the operation manager, but a time display part, a key input operation part, a key lock means, etc. The problem is that the number of parts increases, the configuration becomes complicated, the size is hindered, and the cost is increased, so that it is difficult to provide equipment using a narrow space.

The present invention has been made in view of the above points, and an object of the present invention is to make it possible to easily set and correct time without providing a key input operation unit on the front of a case of a data collection processing device. It is another object of the present invention to provide a device capable of preventing an arbitrary change by a driver and achieving downsizing and compactness.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a memory card with:
In advance, time setting data for time setting or time correction data for time correction is written, and the written memory card is inserted and connected to a card insertion slot provided on the front surface of the case of the data collection processing device. The time setting or the time correction of the clock section is performed by the time setting data or the time correction data.

<Operation> Insert the memory card with the time setting data or time correction data written into the card insertion slot provided on the front of the case. Thus, the data collection processing device reads the time setting data via the card writing / reading unit, sets the time setting data on the clock unit, and sets the time. The time correction data is arithmetically processed at the current time read from the clock unit to correct the advance and delay of the time.

<Embodiment> An embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 1 denotes a memory card for recording operation data, and as shown in FIG.

Reference numeral 2 denotes a vehicle speed sensor that outputs a pulse signal proportional to the running speed of the vehicle. For example, a magnetizing ring for detecting the traveling speed is attached to the outer periphery of a rotating body that is inserted and cooperated between a vehicle speed measuring output shaft in a transmission and a flexible wire connected to a speedometer, and a hole is attached to the magnetizing ring. The running speed is detected by generating a pulse signal proportional to the rotation speed of the output shaft by causing a magnetic sensor such as an element to approach and count the number of magnetizations of the magnetized ring. Reference numeral 3 denotes a switch sensor that detects and outputs an on / off signal of the engine key switch 4 connected to the battery 5. When the engine key switch 4 is turned on, for example, a transistor connected to a constant voltage power supply is made conductive, and the collector output of this transistor is sent out as a detection signal via a knot circuit. 6
Is a data collection processing device that is connected from the vehicle speed sensor 2 and the switch sensor 3 to collect and process the operation data of the vehicle, and to record the data in the memory card 1 that is detachably inserted and connected. This means that the pulse signal of the vehicle speed sensor 2 is instantaneously given a predetermined sampling period (for example, 0.
An interface unit 7 for outputting a value counted every 2 seconds) as vehicle speed data, a detection signal of the switch sensor 3 as a parking / stop determination signal, an arithmetic processing unit 8 for arithmetically processing the output thereof, and a serial processing unit. A clock unit 9 that has an I / O calendar clock LSI and a backup power supply and outputs date, hour, minute, and second data, and a read-only memory that stores a program for collecting and processing operation data ( A random access memory (hereinafter referred to as an internal memory) 11 for storing data processed by a program read from the ROM 10;
The operation data is written into the memory card 1 by detachably inserting and connecting the memory card 1, and the “L” level output signal from the card detection unit 1 d is inserted into the card 1 by the insertion of the card 1. And a card writing / reading section 12 adapted to be taken in as a detection signal of arrival, and based on input signals of the vehicle speed sensor 2 and the switch sensor 3, the date and time of start of travel, hour / minute / second, travel speed, travel distance And data collection processing of operation data such as parking and stopping times. As shown in FIG. 3, the data collection processing device 6 includes a memory card 1 on a front panel 6b of a box-shaped case 6a via a card writing / reading unit 12 and a holder (not shown). A card insertion slot 6c for detachably inserting and connecting, a card ejection button 6d for pushing out a memory card 1 inserted by pushing a button, and a memory card 1
And a running lamp 6f, which is lit when the engine key switch 4 is turned on and off, and a card insertion lamp 6e which is lit and displayed by inserting the card.

Then, the operation recording device A thus configured is installed in the vehicle.

next. The operation of setting and correcting the time for the clock unit 9 of the data collection processing device 6 will be described with reference to FIGS.

A. Time setting First, time setting data is recorded on the memory card 1. This means that, for example, if the time for the clock unit 9 is set to 9: 00: 00: 00, the memory card 1 is inserted into an external computer (not shown) and the specified address of the memory unit 1a of the card 1 is set. , A time setting request flag is added to the top of the field, and time setting data of year, month, day, hour, minute, and second are sequentially written. After writing,
When the time when the memory card 1 was removed from the external computer and the memory card 1 was written was reached, the card opened on the front panel 6b of the case 6a of the data collection processing device 6 mounted on the vehicle. It is inserted into the insertion slot 6c, and is inserted and connected to the card writing / reading unit 12 via a holder (not shown). The card detection unit 1d detects this insertion connection and sends out an output signal, so that a card insertion lamp on the front panel 6b is detected.
6e lights up.

Then, as shown in FIG. 4, first, the arithmetic processing unit 8 determines whether there is a time setting request via the card writing / reading unit 12 (100). The data is read (101), the mode of the clock unit 9 is switched to the time setting mode (102), and the time setting data is set in the clock unit 9 (103). Next, the mode of the clock unit 9 is switched to the time counter mode, the current time (that is, the set time) is read (104), and it is determined whether or not the read current time matches the time setting data (10).
5) If they match, the setting request of the memory card 1 is cleared (106), and the time setting operation ends.

After setting the time, the memory card 1 inserted and connected is connected.
Is kept as it is and the operation data accompanying the start of traveling is recorded.

At this time, if the time is not set according to the time setting data in step 105, a setting error is recorded on the memory card 1 (107).

This means that the clock section 9 of the data collection processing device 6 and the arithmetic processing section 8 are abnormal, and the operation manager is required to submit the memory card 1 from each driver and to discover the data when analyzing the data. And the data collection processing device 6 of the vehicle is inspected.

B. Time Correction Next, when the time of the operation data recorded on the memory card 1 is advanced or delayed significantly due to a change with time, the time is corrected.

First, similarly to the time setting described above, a flag for a time correction request is added to the head of the specified address of the memory card 1 to advance the time correction data (for example, 5 minutes). Then write.

As described above, the memory card 1 into which the time correction data is written is inserted into the card insertion slot 6c of the case 6a of the data collection processing device 6 of the vehicle, and is inserted and connected to the card writing / reading unit 12. As a result, as shown in FIG. 5, it is determined whether there is a time correction request (200). If there is a request, the current time is read from the clock unit 9 (201), and the time correction data is read from the memory card 1 (201). (E.g., 5 minutes) is read (202), and it is determined whether the time correction is a delay correction or an advance correction (203). If the time correction is a delay correction (i.e., if the time is late), the time is corrected to the read current time. The delay is corrected by adding the data (204). Next, the corrected time is set (206). This is similar to the time setting operation described above. First, the mode of the clock unit 9 is switched to the time setting mode, the corrected time data is set in the clock unit 9, and then the mode of the clock unit 9 is switched to the time count mode. To read the current time (i.e., the correction time) to determine whether or not this matches the corrected time.
If they match, the correction request of the memory card 1 is cleared (207), and the time correction operation ends. If the time is advanced and corrected in step 203 (that is, if the time is advanced), the time correction data is subtracted from the read current time (205), and the steps 206 and 207 are executed.

When the corrected time is set in the clock unit 9 and the read current time does not match the corrected time,
As in step 107 described above, a correction error is recorded on the memory card 1.

As described above, since the time can be set and corrected by the memory card 1, the arrangement of components on the front panel 6b of the data collection processing device 6 is also simplified, and the width W and the height H are reduced. This makes it possible to reduce the size and size of the data collection and processing device 6 and to use equipment that uses a narrow space as an optional in-vehicle device.

<Effects of the Invention> According to the present invention, time can be set and corrected by a memory card that records operation data.
The data collection and processing device installed in the vehicle can be configured without providing a key input operation unit and a time display unit on the front of the case, reducing the number of parts, making it compact, compact, and inexpensive. It can be. In addition, the time can be set and corrected only by the driver inserting and connecting the memory card in which the time setting data or the time correction data is written in advance by the operation manager, so that any change by the driver can be prevented. And can be done easily. Moreover, running can be started continuously with the memory card inserted and connected, and operation data can be recorded, so that operability can be improved without hindering business performance.
