Description
Technical field
The present invention relates to a kind of hydraulic digger operating device multiple mode power automatic control system, it is adaptable to mechanical field.
Background technology
In earth and rock works, because the difference such as soil class, grading of soil and soil moisture content makes the mechanical property difference of soil very big, therefore, for the soil load for varying, often difference is very big for the energy of the confidential consuming of hydraulic excavating.In real work, subjective judgement usually is carried out to required digging force size by operating personnel, then operated using manual power regulating system.Obviously, this power adjusting mode subjectivity is big, and the power of engine can not be utilized effectively, and the operating efficiency of hydraulic crawler excavator can also be under some influence.
The content of the invention
The present invention proposes a kind of hydraulic digger operating device multiple mode power automatic control system, the change that the automatic control system can preferably adapt to extraneous load is operated pattern and automatically selects, system has degree of precision and sensitivity, so as to the labour intensity for realizing improving work operations efficiency, reducing system energy loss, reduce operating personnel, overall performance is finally improved.
The technical solution adopted in the present invention is：The situation of outer load is passed to pressure sensor by the automatic control system target, and by signal transmission to controller, controller sends signal control arrangements for speed regulation to sensor.Then the rotating speed to engine is adjusted, it is set to be adapted automatically with the power needed for outer load, so operating personnel can just free from the operation of power mode is frequently manually set, and finally realize the Automated condtrol of hydraulic digger operating device power adjusting.
The use single-chip microcomputer STC900516RD+ is used as core control element, specific model STC90C516RD+40I-PDIP40, it is a single-chip microcomputer that macrocrystalline science and technology STC is newly released, with low-power consumption, antijamming capability is superpower, capacity is big, the speed of service is fast and the features such as low-power consumption.Because its kernel is still 51 single-chip microcomputers, thus it is completely compatible with the instruction of traditional 8051 single-chip microcomputer, do not interfere with writing for program.Therefore, if can not find the model of single-chip microcomputer selected by system in Software for Design, other corresponding 51 single-chip microcomputers present in software can be selected to be replaced.
The information gathering of the hydraulic digger operating device power adjusting automatic control system is obtained by 3 pressure sensors, and they are separately mounted on bucket cylinder, bucket arm cylinder and boom cylinder.The working range of the pressure sensor of selection is greater than 51MPa from West Germany's good fortune P33S3 B086002 pressure transmitters as work information harvester, and its measurement range is 0 ~ 40MPa.
The working condition acquiring circuit of the system uses 3 identical data acquisition channels, and the side pressure force information of bucket cylinder, bucket arm cylinder and boom cylinder is gathered successively, and then this group of data are analyzed and processed by single-chip microcomputer.Single-chip microcomputer first has to be analyzed treatment to every group of data, and then output control signal, is controlled finally by power control circuit to engine, so as to realize hydraulic digger operating device Power auto-adjustment.
The beneficial effects of the invention are as follows：The change that the automatic control system can preferably adapt to extraneous load is operated pattern and automatically selects, system has degree of precision and sensitivity, so as to the labour intensity for realizing improving work operations efficiency, reducing system energy loss, reduce operating personnel, overall performance is finally improved.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the overall plan schematic diagram of hydraulic digger operating device power adjusting automatic control system of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As the situation of outer load is passed to pressure sensor by Fig. 1, automatic control system target, by signal transmission to controller, controller sends signal control arrangements for speed regulation to sensor.Then the rotating speed to engine is adjusted, it is set to be adapted automatically with the power needed for outer load, so operating personnel can just free from the operation of power mode is frequently manually set, and finally realize the Automated condtrol of hydraulic digger operating device power adjusting.
Using the RD+ of single-chip microcomputer STC90 0516 as core control element, specific model STC90C516RD+40I-PDIP40, it is a single-chip microcomputer that macrocrystalline science and technology STC is newly released, with low-power consumption, antijamming capability is superpower, capacity is big, the speed of service is fast and the features such as low-power consumption.Because its kernel is still 51 single-chip microcomputers, thus it is completely compatible with the instruction of traditional 8051 single-chip microcomputer, do not interfere with writing for program.Therefore, if can not find the model of single-chip microcomputer selected by system in Software for Design, other corresponding 51 single-chip microcomputers present in software can be selected to be replaced.
The information gathering of hydraulic digger operating device power adjusting automatic control system is obtained by 3 pressure sensors, and they are separately mounted on bucket cylinder, bucket arm cylinder and boom cylinder.The working range of the pressure sensor of selection is greater than 51MPa from West Germany's good fortune P33S3 B086002 pressure transmitters as work information harvester, and its measurement range is 0 ~ 40MPa.
The working condition acquiring circuit of system uses 3 identical data acquisition channels, and the side pressure force information of bucket cylinder, bucket arm cylinder and boom cylinder is gathered successively, and then this group of data are analyzed and processed by single-chip microcomputer.Single-chip microcomputer first has to be analyzed treatment to every group of data, and then output control signal, is controlled finally by power control circuit to engine, so as to realize hydraulic digger operating device Power auto-adjustment.
Single-chip microcomputer first has to be analyzed treatment to every group of data, and then output control signal, is controlled finally by power control circuit to engine, so as to realize hydraulic digger operating device Power auto-adjustment.
It is in idling mode (i.e. power mode D) that hydraulic digger operating device power adjusting automatic control system has just been started working, normal conditions system enters people's power adjusting automatic control mode (i.e. automatic mode) automatically carries out Power auto-adjustment, if operating personnel very skillfully directly can carry out power adjusting to the operation skill of hydraulic crawler excavator by button.(thering is key to press to refer to which kind of pattern selected in automatic mode and artificial mode).
When hydraulic crawler excavator is just started working, system is in idling mode (i.e. power mode D), and alarm free shows default mode of auto.
Pressure transmitter is acquired to pressure information and single-chip microcomputer of making a gift to someone is processed, and then is carried out crossing the border judgement and treatment according to result or is carried out power adjusting, and current working condition is shown finally by LCD1602.
Button is pressed can just enter people's artificial mode, then carry out Power Control by the result of keystroke handling, and current working condition is shown finally by LCD1602.
