Description

[Detailed Description of the Invention] The present invention makes it possible to digitally record data separately when heavy machinery such as dump trunks, loaders, other vehicles, machine tools, construction machinery, etc. is operating with positive power and when operating with different power. Regarding the device that enables this.

For example, the daily operation report of construction vehicles, etc. becomes the basic data for vehicle maintenance management, and the presence or absence of abnormalities in each part of the vehicle by inspection of the vehicle from the start to the end of the work day, 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 that this type of driving data is obtained 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 reading, calculation, and storage a major hassle.

For this reason, the recorded results are simply stored as vehicle operation records, and it is not possible to try to optimize the operation method or the like based on the recorded results.

In order to improve vehicle operation efficiency, it is necessary to identify problems and devise improvement methods based on the latest actual operation data, and immediately collect and analyze detailed and accurate operation data.

In particular, when an abnormality occurs such as a vehicle collision, fall, runaway, failure, etc., it is important to record the instantaneous behavior data of the vehicle at that time with high density.

As such recording means, an endless tape recorder is generally used, but in this case, since it is a mechanical recording method, it is unreliable in fields such as construction vehicles that are subject to severe vibrations.

This invention was newly created as a result of intensive research in view of the above circumstances.

The main purpose of this invention is not only to digitally record the operation data of each combo component that is operated when the heavy equipment is operated with positive power, but also to always collect the latest operation data by updating the record. An object of the present invention is to provide an abnormality detection and recording device which also serves as an operation record of heavy machinery, which is capable of separately collecting and recording instantaneous behavior data of the heavy machinery at a high density when an abnormality occurs.

Another purpose of the invention is to extract problems and develop improvement methods based on operational data of heavy machinery components.
An object of the present invention is to provide an abnormality detection and recording device that can record the operation of heavy machinery, which can be performed in J hours and greatly contributes to predicting abnormalities of M machines and improving operating efficiency.

Another object of the present invention is that it is possible not only to record heavy machinery operating data chronologically like a tachograph, but also to record randomly, and because the recording medium has an all-solid element configuration, consumable elements such as ink are eliminated. To provide an abnormality detection and recording device which is maintenance-free and which is suitable for machines subject to severe vibrations such as construction machinery and which also serves as an operation record of heavy machinery.

In order to achieve the above object, the present invention includes a sensor means for detecting the operating status of each component of heavy machinery and converting it into an electrical signal, and a sensor means for detecting the operating status of each component of heavy machinery and converting it into an electrical signal. 1, comprising a monitoring means for determining the presence or absence of an abnormality; a data recording device for inputting digital data from the monitoring means; and a recording medium having an all-solid-state element configuration into which the digital data is electronically written by the recording device. , the recording medium has a normal data memory that updates and stores data written by the recording device when the heavy machinery is operating normally, and a normal data memory that suspends writing and updating to the normal data memory when an abnormality occurs in the heavy machinery. Separately record abnormal data 1. The present invention is characterized in that it has a configuration including: (a) a memory for abnormal data;

Hereinafter, a preferred example of the present invention applied to a construction vehicle will be described with reference to the drawings.

The system of the present invention includes sensor means 1 as a vehicle-mounted device for obtaining operating data of each component of the vehicle using parameters.

The illustrated sensor means 1 includes an hour meter 11 for accumulating engine operating time, a speed meter 1-2 for detecting vehicle running speed, an engine tachometer 1-3, a fuel consumption needle 1-4, and a hydraulic system. It consists of pressure gauges 1-5, oil temperature gauge 1-6, and vibration gauge 1-7.

Such sensor means 1 is connected to monitoring means 3 via an A/D converter 2.

The monitoring means 3 consists of a logic circuit that determines whether an abnormality has occurred in the input system components based on the input signal from the sensor means 1, and has an output terminal connected to the alarm means 4, the emergency stop means 5, and the data recording device 6. It is connected to each of the CRTs 13.

In addition to the monitoring means 3, the input section of the data recording device 6 is also connected to an external input means 8 such as a keyboard, and a memory 6 for temporarily storing input data from them.
-1, the stored digital data is stored in the recording medium 7.
is written electronically.

The recording medium 7 has a memory 7-1 for normal data during normal operation of the vehicle and a memory 7-2 for data during abnormal operation, and is inserted and set in the data recording device 6 in a freely insertable and removable manner.

In the normal data memory 7-1, the time-series data of the components during normal operation of the vehicle is digitally recorded by the recording device 6. In this case, the time-series data is stored in the memory 7-1 at its starting address. The data is written and updated on a first-in, first-out basis.

The writing is updated at the time when an abnormality in the vehicle is detected.
1i, and the abnormality occurrence data in this case is written to the abnormal data memory 7-2, which is different from the normal data memory 7-1.

In such a recording medium 7, the memory 7-1 is an ultraviolet erasable memory (
f element or static ink RAM or RA
It is composed of an integrated circuit such as M, and has an all-solid-state element configuration in which it is housed and combined in a card, module, plastic box, casing, etc.

The above system is installed on the vehicle side, and a device 10 for reading and reproducing data recorded on the recording medium 7 is installed in this type of vehicle operation management office.

This reading/reproducing device 10 includes a reading function unit (decoder) 10-1 for reading data written on a recording medium 7 inserted in a removable manner, and a reading function unit (decoder) 10-1 for calculating input data from the function unit. It has a computer configuration having an arithmetic function section 10-2 for processing, and a terminal device 12 connected to its output terminal via a D/A converter 11.

The illustrated terminal device 12 includes an X-Y plotter 12A and a printer 12B.

In the above, the vehicle-side system is started by starting the vehicle-mounted engine.

In this case, the recording medium 7 is inserted and set in the data recording device 6 in advance.

When the system starts in this state, that is, at the same time as the engine starts, the date and time are first recorded in the memory 7-1 of the recording medium 7 by the clock mechanism provided in the data recording device 6.

When starting the engine and operating the vehicle,
Engine speed, fuel consumption, hydraulic system temperature and pressure,
Time-series data of vehicle components such as traveling speed and amount of vibration of the vehicle body are detected by the sensor means 1 as analog data.

The detected analog data is converted into a digital quantity by the Δ/D converter 2 and inputted to the monitoring means 3.

The monitoring means 3 determines whether field lightning occurs 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 in synchronization with the check timer signal at that time is reproduced on the CRT 13.

At the same time, the normal operation data is input by the recording device 6 and written into the normal data memory 7-1 of the recording device 7 via its own memory 6-1.

The writing continues as long as no abnormality occurs in the vehicle component. In this case, the current data memory 7-
1 is sequentially written and updated in a first-in/first-out manner starting from the first address as described above, so that the latest normal operation data is always stored in the memory 7-1.

In the process of writing normal operation data, when the monitoring means 3 determines that field lightning has occurred in a vehicle component, the abnormality occurrence signal is used to write the normal data memory 7-1.
Write update to is interrupted.

At the same time, the abnormal operation data of the vehicle component is written by the recording device 6 into the abnormal data memory 7-2, which is different from the normal data memory 7-1 in the recording medium 7, and is also displayed on the CRT 13.

Further, the monitoring means 3 operates the alarm means 4 and the emergency stop means 5, respectively, in response to the abnormality occurrence signal.

In this case, the alarm means 4 is activated regardless of the degree of abnormality, but the emergency stop means 5 may be activated only when the degree of abnormality is high to automatically stop the vehicle. preferable.

Thus, the end of vehicle operation or vehicle component I
When the engine is stopped when an abnormality occurs, the operation end date and time or the abnormality occurrence date and time and operating time are written to the recording medium 7 described above.

In addition, this recording medium 7 also includes information on the operation of the vehicle 11 as described above.
In addition to the time series data of time and components, the date and time of service end, date and time of abnormality occurrence, and operating hours, vehicle inspection and maintenance data, such as fuel filler and oil change date and time, which are artificially input into data recording device 6 using external input means 8. , cargo handling
The number of lu times, amount of work, repair data, etc. are also electronically written as digital quantities by the recording device 6.

Therefore, the recording medium 7 becomes a collection of all kinds of information, including not only normal operation data and abnormal operation data of the vehicle, but also related data.

The recording medium 7 is taken out from the data recording device 6 by the vehicle operator and brought back to a management office or the like, where it is loaded onto the reading/reproducing device IO.

In this case, the recording medium 7 is stored in the decoder 10-1 of the device 10.
When the memory 7-1 is inserted and set, all 10 data written in the memory 7-1 are recalled.

The call data is sent from the decoder 10-1 to the arithmetic function unit 10.
-2.

When the input data is normal operation data of the all-ζ vehicle, the calculation function unit 10-2 records the vehicle's maximum speed, average speed, full stroke speed table, instantaneous acceleration, engine wear information, etc. based on the data. Normal data memory 7- of medium 7
All the latest data regarding wheel operation written in 1 is calculated and reproduced. In addition, if data is also written in the abnormal data memory 7-2 of the recording medium 7, that data can also be input to determine the vehicle's lightning acceleration, maximum inclination angle, and time until engine stop. Calculates the progress etc. and reproduces it.

The resulting data is X-Y plotter 12A and printer 1.
2B is output by each of them.

Furthermore, the data written on the recording medium 7 is stored in the playback device 1.
It is also possible to electronically transfer the information to another large-capacity recording medium such as a floppy disk, magnetic tape, etc., on which even larger amounts of information can be filed via the reading function section 10-1 of 0.

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 operation procedures in advance in the recording medium 7.

Further, the recording medium 7 may be an optically modulated disk that can be programmed manually.

As described above, according to the present invention, normal operation data of a heavy machine such as a vehicle and abnormal product operation data can be collected and recorded separately on a recording medium such as an IC card.

In particular, since the normal operation data is sequentially updated when it is recorded on the recording medium, the heavy equipment management side can instantly read the latest operation data of the heavy machinery using the recording medium.

In addition, as mentioned above, the abnormal product operation data is recorded on the recording medium separately from the normal operation data, so it is possible to collect and record instantaneous behavior data at a high density when an abnormality occurs in heavy equipment. This makes it possible to quickly determine the cause of field lightning on a vehicle.

Therefore, using the recording medium, problems in the operation of heavy machinery can be quickly identified and improvement methods can be devised, which greatly contributes to predicting abnormalities in heavy machinery and improving operating efficiency.

In addition, since the recording medium has an all-solid-state element configuration, it is maintenance-free and is ideal for operating machines that are subject to severe vibrations, such as construction machinery. can exist.

Of course, the present invention is applicable not only to vehicles but also to construction machines, machine tools, and various other operating machines.
