Description

[Detailed description of the invention]

[Field of Industrial Application] This invention detects operating data of construction machines and other equipment, records them in a card-type memory, and determines abnormalities. This invention relates to an operation recording device.

[Conventional technology]

For example, daily operation reports of construction machinery, etc. are the basic data for vehicle maintenance and management, and inspections of vehicles from the start to the end of the day to find out whether any abnormalities have occurred in each part of the vehicle, the operating hours of the day, and usage records of fuel, oil, etc. are simply expenses. This is important not only for basic calculation data, but also for predicting vehicle abnormalities. However, it is well known in the art to obtain this type of driving data using a mechanically driven tachograph. However, in the case of a tachograph, only the running speed and distance traveled are recorded in analog form, and furthermore, the data written on the recording paper must be read visually, making the reading, calculation, and storage extremely complicated. . For this reason, the recorded results are simply stored as vehicle operation records, and it is not possible to attempt to optimize driving methods or procedures based on the recorded results. Therefore, in recent years, configurations have been proposed that use sensors to digitally record operational data. A configuration is disclosed in which measurement data is stored in a small memory package that can be inserted into and removed from the above device, and the stored contents are processed by a computer. When such digital data is recorded in a memory pack, the memory pack only has a structure for storing data. For this reason, since the recorded results are simply stored as vehicle operation records, it is not possible to determine abnormalities or dangers based on the recorded results. In order to improve vehicle operation efficiency, it is necessary to identify problems and develop improvement methods based on actual operation data.
It is necessary to collect and analyze detailed and accurate operation data. Furthermore, in such a memory package as a storage medium, operating data is recorded even if it is used illegally by a third party, so accurate data cannot be obtained unless other means are provided.

[Problems to be solved by the invention]

In view of the above circumstances, the present inventors have proposed a device that detects operating data of each component of construction machinery and other vehicles, records it in a card-type memory, and determines abnormalities based on the detected values, and also The present invention was developed based on the idea that if the type memory also had the function of starting a vehicle's engine, unauthorized vehicle operation could be prevented, operating data could be obtained correctly, and theft could be prevented. be.

[Means to solve the problem]

In order to achieve the above-mentioned problem, this invention attaches a removable card type memory to a data recording device mounted on a vehicle, and collects operating data of the vehicle detected by a sensor installed on the vehicle and external input means. The input memory data (or refueling, repair, inspection data, etc.) of the vehicle is recorded in the card-type memory, and the recorded card-type memory is installed in a data processing device installed in a management office, etc. In the vehicle operation recording device that analyzes and processes the recorded data, (a) the sensors installed in the vehicle include a vehicle speed sensor, an engine rotation speed sensor, a fuel consumption sensor, an oil pressure sensor, an oil temperature sensor, and a vibration sensor; (b) Monitoring that determines an abnormality when the value of the data exceeds a preset value (abnormal value) based on the detection data detected from each of the above sensors. Provide means. (c) Provide an alarm means that activates when the monitoring means determines that there is an abnormality, or an emergency stop means that activates when the abnormal value exceeds a preset value (danger value) to stop the vehicle from running. (d) providing a data recording device for recording detection data detected by the sensor in a card-type memory; (e) providing a data recording device in an insertion slot into which the data recording device is inserted to write data to the card-type memory; (f) a switch main body component that opens and closes the engine starting circuit of a vehicle by inserting the switch operating component; The technical measure is to form a switch actuating component that closes the switch.

[Effect]

Operating data is calculated based on signals detected from some or all of the vehicle speed sensor, engine rotation speed sensor, fuel consumption sensor, oil pressure sensor, and vibration sensor, and together with the operating data of the vehicle input from external input means. Write to card type memory. In addition, the operating data detected from the above sensor is input to the monitoring means and it is determined whether it exceeds a preset value (abnormal value), and if it exceeds it, the alarm means is activated to issue a warning to the operator. . In addition to or in place of the above alarm means, if the abnormal value becomes larger and exceeds a preset value (danger value), an emergency stop means is activated to stop the vehicle. When the card-type memory used to record this operating data is inserted into the insertion slot of the data recording device, the switch operating component of the card-type memory comes into contact with the switch main body component provided in the insertion slot, and the switch is turned on. Ru. Since the switch main body component is connected to the engine starting circuit of the vehicle, the engine of the vehicle is started by turning on the switch.

The illustrated sensor means 1 includes an hour meter 1-1 for accumulating engine operating time, a speed meter 1-2 for detecting vehicle running speed, an engine revolution meter 1-3, and a fuel consumption meter 1-4. The hydraulic system consists of a pressure gauge 1-5, an oil temperature gauge 1-6, and a vibration gauge 1-7. Such sensor means 1 are connected to a data recording device 6. In addition, oil pressure gauge 1-5, oil temperature gauge 1-6, vibration meter 1-
7 shows the detection signal as an analog quantity, so A/
It is connected to a data recording device 6 via a D converter 2. The monitoring means 3 consists of a logic circuit that determines whether or not an abnormality has occurred in the input system components based on the input signal from the sensor means 1, and has output terminals connected to the alarm means 4, the emergency stop means 5, and the data recording device 6. and CRT13 respectively. The input section of the data recording device 6 is connected not only to the monitoring means 3 but also to an external input means 8 such as a keyboard, and is equipped with a memory 6-1 for temporarily storing input data. Data is electronically written into the card type memory 7. In this embodiment, the card type memory 7 is an IC card, and is inserted and set in an insertion slot 20 into which data is inserted to write data to the card type memory of the data recording device 6. It has a normal data memory 7-1 in which normal vehicle operation data is written and an abnormal data memory 7-2 in which abnormal vehicle operation data is written. Therefore, the data recording device 6 is a card type memory 7.
The insertion port 20 is connected to a system start circuit (not shown) of the data recording device and a start circuit C for starting the engine installed in the vehicle, as shown in detail in FIG. A switch main body component 15 is provided. In the present invention, the switch main body component 15 may be connected only to the start circuit C for starting the engine installed in the vehicle, as shown in the drawing. On the other hand, the card type memory 7 is provided with a switch operation component 16 on its surface for turning on the switch main body component 15 when the data recording device 6 is inserted into the insertion slot 20. Although the switch operation component 16 in the illustrated example is made of a conductor such as conductive foil provided on both the upper and lower surfaces of the card-type memory 7, the present invention is not necessarily limited thereto. For example, card type memory 7
The switch operation component 16 is electromagnetically connected inside the insertion slot of the data recording device 6 to secondarily operate the switch main body component 15, or the tip of the card type memory 7 is the switch operation component. 16
Therefore, the insertion may be performed by mechanically operating the switch main body component 15 (for example, via a link mechanism), and in either case, similar effects can be obtained. In the card-type memory 7, the time-series data of the components during normal operation of the vehicle is digitally recorded in the normal data memory 7-1 by the recording device 6. In this case, the time-series data is stored in the memory 7-1. 7-1 is written and updated from the first address in a first-in, first-out manner. The writing update is interrupted at the time when the occurrence of an abnormality in the vehicle is detected, and the abnormality detection data at this time is written into another abnormality data memory 7-2. In such a card type memory 7, each of the memories 7-1 and 7-2 is composed of an ultraviolet erasable storage element or an integrated circuit such as static RAM or dynamic RAM, which is housed in a card type and combined into an all-solid-state element structure. It's summery. The above is a system connected to the vehicle side, and a device 10 for reading and reproducing data written in the card type memory 7 is installed in this type of vehicle operation management office and the like. This reading/reproducing device 10 includes a reading function section (decoder) 10-1 for reading data written into a card-type memory 7 which is removably inserted therein.
and an arithmetic function section 10-2 for arithmetic processing of input data from this function section, and an A/D converter 11 at its output terminal.
The terminal equipment 12 is connected via a terminal device 12. The terminal device 12 in the illustrated example is an X-Y blocker 12
A and a printer 12B. In the above, when the card type memory 7 is inserted into the data recording device 6, the switch main body component 15 is
When turned ON, the start circuit is closed and the vehicle-mounted engine is started, and at the same time, the system skirt circuit is closed and the system of the data recording device 6 is started. At this time, the date and time are first recorded in the normal data memory 7-1 of the card type memory 7 by the clock mechanism included in the data recording device 6. When the vehicle is in operation, the sensor means 1 detects time-series data of the vehicle components, such as engine speed, fuel consumption, temperature and pressure of the hydraulic system, traveling speed, and amount of vibration of the vehicle body. Of the detected signals, analog data is converted into digital quantities by the A/D converter 2 and inputted to the monitoring means 3. The monitoring means 3 determines whether an abnormality has occurred in any of the vehicle components based on the input data. As a result of the determination, if no abnormality has occurred in any of the vehicle components, normal operation data of the vehicle synchronized with the check timer signal at that time is reproduced on the CRT 13. At the same time, the data recording device 6 inputs the normal operation data to the normal data memory 7-1 of the card type memory 7 via its own memory 6-1.
Written to 1. The writing continues as long as no abnormality occurs in the vehicle components. In this case, since the normal data memory 7-1 is sequentially written and updated in a first-in, first-out manner starting from the first address as described above, the latest normal operation data is always stored in the memory 7-1. be done. In the process of writing such normal operation data,
When the monitoring means 3 determines that an abnormality has occurred in a vehicle component, the abnormality occurrence signal interrupts writing and updating to the normal data memory 7-1. At the same time, the abnormal operation data of the vehicle components is transferred to the normal data memory 7- in the card type memory 7.
The abnormal data memory 7-2, which is different from the abnormal data memory 7-2, is written by the data recording device 6, and is also displayed on the CRT 13. Further, the monitoring means 3 activates each of the alarm means 4 and the emergency stop means 5 based on the abnormality occurrence signal. In this case, the alarm means 4 is activated regardless of the degree of abnormality occurrence, but it is preferable that the emergency stop means 5 is activated only when the degree of abnormality is high to automatically stop the traveling vehicle. In this manner, when the engine is stopped at the end of the vehicle operation or when an abnormality occurs in the vehicle components, the date and time of the end of the operation or the date and time of the occurrence of the abnormality and the operating time are written in the card type memory 7 mentioned above. In addition to the above-mentioned operation date and time of the vehicle, time-series data of component parts, operation end date and time, or abnormality occurrence date and time and operation time, this card-type memory 7 also contains the data recording device 6 by external input means 8. For example, vehicle inspection and maintenance data such as refueling date and oil change date and time, the number of times of cargo handling and transportation, amount of work, repair data, etc. that have been inputted are also electronically written as digital quantities by the recording device 6. Therefore, the card-type memory 7 becomes a collection of all kinds of information, including not only normal operating data and abnormal operating data of the vehicle, but also related data. The card type memory 7 is taken out from the data recording device 6 by a vehicle operator and brought back to a management office or the like, where it is loaded onto the reading/reproducing device 10. In this case, when the card type memory 7 is inserted into the decoder 10-1 of the device 10 and set, all data written in the memories 7-1 and 7-2 are recalled. The call data is transmitted from the decoder 10-1 to the arithmetic function section 10-2. Arithmetic function unit 10-2
If all the input data is the normal operation data of the vehicle, the memory 7 for normal data of the card type memory 7 includes the vehicle's maximum speed, average speed, full stroke speed table, instantaneous acceleration, engine wear information, etc. based on the data. -1 and calculates and reproduces all the latest data related to vehicle operation. If data is also written in the abnormal data memory 7-2 of the card-type memory 7, that data can also be input to determine the vehicle's abnormal acceleration, maximum inclination angle, and time until engine stop based on that data. Calculate and reproduce the progress. The resulting data is output by X-Y block 12A and printer 12B, respectively. Further, the data written in the card type memory 7 is electronically transcribed to another large capacity recording medium such as a floppy disk or magnetic tape on which even larger amounts of information can be stored via the reading function section 10-1 of the playback device 10. It is also possible to do so. In this case, there is an advantage that the operation data of a large number of operating vehicles can be centrally managed. Note that it is also possible to store vehicle operating procedures in the card-type memory 7 in advance. Further, the card type memory 7 may be composed of a light modulation disk on which a program can be input. In short, in this invention, the outer shape of the card type memory is not limited to a substantially rectangular plane shape, but may be disk shaped.
The method doesn't matter.
