Description
Technical field
The present invention relates to for example, digger arm for annex (scraper bowl) being connected to removedly to excavator, for example, from the driver's cabin of excavator, this hookup is provided with status sensors.
Background technology
Known for the hookup itself that at a distance annex is connected in to the digger arm of excavator.But seldom such hookup has the sensor being configured in self.But, be known with such hookup of sensor, a kind of such hookup is open in the EP1318242 of Geith Patent Co., Ltd.This file discloses a kind of hookup, it has sensor and control electronic installation, this sensor is used for surveying when hookup has been moved to encirclement position (crowd position) (, completely crimped position), this control is only used for allowing starting separable programming during in this encirclement position when this hookup with electronic installation.This encirclement position is regarded as the home for separating of program, because in this encirclement position, this hookup is configured to its front jaw and is directed upwards towards at least in part, annex to be connected or that separate can not drop from this hookup thus, the every other maintaining body that is used in this annex is released entirely, and this hookup has had the connecting pin that is positioned at front jaw.
The link system that comes of another kind of prior art discloses in US2004/0244575.Its same searching is surrounded position.But it is to realize by the full extension of in the hydraulic cylinder of supervision digger arm, this cylinder makes to surround position generation.
Although there is the instruction of prior art, but still likely user error use hookup, for example, annex is not correctly connected to and on hookup, just transmits annex, for example only the connecting pin of annex be hooked on front jaw and do not complete linker (, by the second connecting pin of annex is engaged/locks onto in the deutomala of hookup).This incorrect use will produce dangerous situation because connector often can shake this front jaw, if or this arm and hookup not curling its can be unexpectedly from this jaw discharge.This danger is general especially, because whether this annex is properly connected on this hookup always directly not visible, for example, when after lunch, user turns back to excavator, and due to the frequent extreme weight of annex and large, particularly in mining industry, thus accidental separation can to user and around personnel bring grievous injury risk.
Summary of the invention
Therefore the present invention aims to provide a kind of mechanism, and this mechanism prevents or stoped the joint of user in the case of the incorrect use of such hookup.
According to the present invention, hookup is provided, and this hookup comprises the first jaw, and this first jaw is roughly pointing on longitudinal direction with respect to the framework of this hookup, this jaw is for receiving the first connecting pin of annex, wherein for this jaw arranges sensor for surveying connecting pin existence therein.
Sensor can be suitable for output signal to represent connecting pin existing in this jaw.Alternatively or additionally, sensor can be suitable for output signal to represent not detect connecting pin in this jaw.
The signal of sensor can be transmitted or send to receiving element or to conveyer, the indication of the information being detected to allow is delivered to user.This transmission can be along wire, or can be wireless, for example radio transmitting.Such RTTY feed technique is known at automotive field.For example enter system, tire stress monitoring system without key and for mobile phone being connected in to the bluetooth of vehicle audio frequency system
system.
The user who is delivered to detected information preferably sees, hears or feel indication, and he is in the driver's cabin of excavator simultaneously, and this hookup is connected on excavator.Therefore, receiving element or display/indicator means for this reason can be integrated in the instrument panel of excavator.In another is arranged, receiving element or display/indicator means for this reason can be set to one or more independent parts, to be assembled on excavator or in excavator, or preferably in the driver's cabin of excavator.So whether the user in driver's cabin thus notified connecting pin is positioned in this first jaw.
Sensor can be strain transducer.This can survey the existence of connecting pin in jaw, because annex and digger arm are conventionally all very heavy.Therefore,, even if annex rests on the ground, the weight of annex or the weight of arm will conventionally be exerted all one's strength and are applied on this jaw by the connecting pin of annex.This power will be oppressed this jaw, produce thus detectable strain, may be in the throat of this jaw.Thus, the strain meter that is arranged in this jaw place or this jaw can be surveyed the existence of connecting pin at this jaw.
Other possible sensors can be feelers, for example, and PTM (pressing) switch.But other possible sensors can be that Magnetic Sensor-connecting pin is conventionally by steel making.But, it will be understood by those skilled in the art that many different sensors or its combination can be used to survey the existence of connecting pin in this jaw or not exist.The advantage of strain transducer is, it can survey the existence of connecting pin, and no matter this pin props up wherein against this jaw, because strain will be distributed in around the throat of this jaw.
Hookup can also comprise the second jaw, and its framework with respect to this hookup and this first jaw are longitudinally spaced apart.This second jaw preferably faces down in fact, that is, and approximately perpendicular to the first jaw, and away from the end of arm that is connected to the excavator on this hookup.This second jaw is for receiving the second connecting pin of this annex, and it is preferably associated with pivotable or slide lock, and this pivotable or slide lock are for being locked in the second connecting pin in this second jaw.But, in some known hookups, only provide pivotable or slide lock-jaw to be omitted.
Preferably, sensor and the second jaw or pivotable or slide lock are associated.This second sensor can replace this first sensor, or it is other to remove this first sensor.
This second sensor is preferably also for surveying existence and the disappearance of connecting pin.But this detection is for the second pin, or for pivotable or slide lock, rather than for the first jaw.
Preferably, this second sensor is directly installed in this pivotable or slide lock or in this pivotable or slide lock, or on the replacement locking mechanism of this second jaw or in this locking mechanism.But it is most preferred being arranged in pivotable or slide lock or in this pivotable or slide lock, because most of business hookup has hook pivot or sliding panel, so that such lock function to be provided.
Preferably, this second sensor is strain transducer.But, can provide any suitable sensor, as for first sensor.
The second sensor can have the feature similar or identical with first sensor.But, when transmitting when signal to receiving element, the source of signal (, about they from sensor) distinguished by receiving element.For wirelessly transmitting, this can encode or even easily realize with single conveyer by using at the ID transmitting in signal, and this single conveyer transmits the signal of two sensors for the mode that can approve with receiver.Such coding techniques is known in RTTY feed technique, for example tire pressure monitoring device.
It shall yet further be noted that sensor and conveyer can easily be reinforced by using for the design of tire pressure monitoring device research and development, the environment being exposed to deal with hookup.After all, such prior art systems is designed to deal with high-speed tire environment, and the relevant power that wherein run into.Therefore, herein without suitable sensor and the specific design of conveyer are further discussed.
For the indicator unit of indicating the information detecting to user preferably at the driver's cabin of excavator.It preferably has visual detector.They preferably provide the indication of the connection status of the first and second jaws dividually,, whether have connecting pin in each jaw that is.In simple embodiment, can use lamp for each jaw.For example, in the time that connecting pin is positioned at relevant jaw, or connecting pin is not or not the time of relevant jaw, can light the lamp for this jaw.Therefore, user can determine the annex engagement state of this hookup immediately.
In a preferred embodiment, green light represents safety, and red light represents danger.Therefore, in the time that two jaws are correctly bonded on pin, that is, the sensor of front jaw detects the existence of pin, and the sensor of rear lock also detects the existence of pin, and two green lights are shown on indicator unit.This has indicated the safety of annex on hookup to install.But, if an only pin detected, can put and send out a warning.This has indicated unsafe installment state.
In replacing and arranging, when the first jaw is correctly when double pointed nail, can there is green light to show, and show for the second jaw red light, until selling, this second jaw and second correctly engages.
Can also be, in the time not having connecting pin to be detected, point gives a green light because this hookup can not be connected to annex, thus this be safe-do not have annex to fall down the risk of this hookup.This is useful, because hookup has lifting hole conventionally, this lifting hole can be for utilizing chain or rope to promote article.
The 3rd sensor and the 3rd lamp can be incorporated in hookup at hydraulic cylinder place.It can be by determining that the state of cylinder detects the position of this latch mechanism.This status information can also be sent to receiver with assessment and analysis.Equally, can provide sensor to detect the orientation of this hookup.
These and other sensors can use the real image of the state that builds hookup together with other sensors, with by control system analysis, this control system can provide suitable warning to user in the time facing a danger situation, or only feed back to user to assist connection or separable programming, because these programs need to be carried out some steps conventionally, and ought (for example complete specific step, the inversion of the retraction of cylinder/advance or hookup) time, this control system can signal user.For various connections and separable programming, ask for an interview WO2008/029112 or GB0808113.5.
Detection system or receiver can be connected to the hydraulic control system of excavator.Utilize such layout, if unsafe state detected, can limit the output of hydraulic system.For example, only detect a connecting pin for example in first (front) jaw, not only can make on display unit to light for the red light of the sensor of the second jaw, and operational capacity that can limited digging horn.For example, promote or oscillating motion can be limited, prevention or slack-off.Such restriction can be to provide the half throttling setting for hydraulic pressure, or for the limit rotation of oscillating structural member.These restrictions can stop carries out unsafe excavating activities, but does not stop with hydraulic pressure to recover from dangerous state.Therefore user can be prevented from or stop utilizing excavator and hookup to carry out unsafe operation.
Except controlling or restriction fluid power, the manipulation of excavator or engine power can also be connected to detection system, or are connected to receiver, if dangerous or unsafe annex state detected thus, can also limit them.This is valuably, because it can additionally prevent the movement of excavator around job site, and annex is arranged on hookup improperly.This further prevents or has stoped incorrect operating personnel's operation, further reduced thus user by own or other people be exposed to the possibility of its self-inflicted precarious position.
In one embodiment, sensor in addition or that separate has formed a part for machining tool recognition system.Machining tool for such system is additionally provided with readable or transmissible indicator.This indicator can be that optics, magnetic, induction or electric capacity are readable, or it can be the signal transmitting, and the signal of this transmission can be received and be read by the sensor of hookup.Such transmission can be via line, or they can be wireless.
In a preferred embodiment, this indicator is that bar code (and sensor be barcode reader) on this hookup or RF (radio frequency) transmit signal, this signal can be in response to the inquiry of the sensor by hookup, or in response to the circuit completing by connection process.Such RF signal is preferably the form of the ID coding of transmission, or is the form of the signal of more information, and this signal comprises ID coding and some other available information.
Other available information are tell-tale or one or more in parameter below preferably: tool types (, scraper bowl, grab bucket or drill bit), instrument weight or instrument ability are (to allow operating personnel, or excavator oneself knows/determines whether excavator is enough to deal with instrument), instrument sequence code (to allow to follow the trail of specific instrument), instrument service life or operation cycle are (to allow operating personnel, or whether know/decision of excavator oneself instrument can also be used safely, or whether it may stand fatigue failure), and tool construction (for example, connecting pin size or link pins interval, know to allow hookup whether instrument can be arranged on hookup).
Equally, sensor can be set on hookup to read the information from excavator or digger arm.For this reason, excavator and/or digger arm can be provided with the indicator can read in addition.Can also be suitable for excavator and/or digger arm for the similar human readable indicator of annex as described above.
Replace by other installation of sensors on hookup or in hookup, this other sensor can be arranged on annex, or on digger arm/excavator, so this hookup has readable/transmissible indicator.
Utilize these other sensor and indicators, can approve hookup, excavator and annex, and therefore, can adapt to by the control of excavator the known limitation of annex, hookup or excavator with electronic installation.For example, if the annex of for example drill bit is connected, may want to limit this excavator about applying great lateral force in Drilling operating period on annex.Utilize such tool identification system, can automatically apply such restriction with electronic installation by the control of excavator, reduced thus or prevented from causing the possibility of the operating personnel's mistake to annex grievous injury.
Preferably, the information detecting is sent to the receiver of excavator, to be processed by the OEMECU of excavator.This ECU preferably has memory, to store the use information for particular tool or annex.
Equally, preferably, ECU and memory bit are in hookup, can store thus about which annex and which excavator and be connected to the information on this hookup, even allow hookup to there is the intelligence of oneself, can refuse to connect the annex outside the ability that drops on this hookup, that is, this annex is too heavy.
Other sensor can be arranged in hookup, to detect the load that puts on hookup during using annex.These sensors can be above mentioned strain meters.During use, they can be for detection of the overload in hookup.These overloads can be hookup (for example, jaw or latch hook) overload or the overload of lifting hole or they can be the overload of annex, for example, if being familiar with this annex, hookup there is maximum load capability, or maximum excavation/Drilling power ability.So this hookup can give the alarm to notify operating personnel this overload situations to operating personnel, or it alternatively sends signal to notify this situation to the recipient/ECU of excavator, and thus, this excavator can automatically apply performance constraint.
Sensor can be provided in hookup or in annex or in excavator, think that hookup/annex/excavator provides trace ability, for example, by using GPS sensor, and remember the mark of each annex/excavator/hookup and the connection of position combination.So institute's canned data can be for locating specific product in the future, or for following the trail of the movement of special article.Logistics and the goods of this permission company can be tracked.In addition, it can also assist to follow the trail of stolen annex or hookup.

With reference to the accompanying drawings, by means of embodiment, specific embodiments of the invention are described.
Fig. 1 schematically shows the excavator being equipped with according to hookup of the present invention; And
Fig. 2 schematically shows the details of this hookup.
The specific embodiment
First with reference to Fig. 1, show excavator 10, it comprises digger arm 12, driver's cabin 14, motor district 16, crawler belt 18 and for controlling the hydraulic cylinder 20 of operation of this digger arm 12.
Hookup 24 according to the present invention is connected to the free end 22 of digger arm 12.For this object, two tie points 26 (seeing Fig. 2) are arranged on hookup 24, and two connecting pin (not shown) extend through these two tie points 26 to connect.The connected system of the type is traditional in the prior art.
Then annex 28 is connected to hookup 24.As a result, excavator 10 can utilize annex 28 to carry out executable operations via its digger arm 12 and hydraulic cylinder 20.
In this embodiment, this annex 28 is scraper bowls, and therefore normal operations is to excavate.
Referring now to Fig. 2, will the other details of hookup 24 be described.
During the top that two arm tie points 26 are positioned in hookup 24 is divided.Then, the bottom of hookup 24 is divided and is had annex link.They comprise front jaw 30 and deutomala 32, the each joint connecting pin of front jaw 30 and deutomala 32, but this is on annex 28.For this object, front jaw 30 roughly longitudinally points to (that is, in Fig. 1 towards driver's cabin) with respect to the main shaft of hookup 24, and deutomala 32 points to downwards, that is, and and towards the main body of annex.Like this, front or the first jaw 30 can be picked up annex by being hooked on the first connecting pin of this annex, after then the second connecting pin of annex can swing to or in the opening of the second jaw.Then,, via pivotable latch hook 34, can close deutomala 32 for fastening the second connecting pin.Therefore, annex 28 is connected on hookup 24 completely.
The above-mentioned feature of hookup is all traditional.Utilize known interchangeable mechanism of the prior art, they are also interchangeable.For example, additional fixed mechanism can be incorporated in this hookup, for example GB2330570 or WO2008/029112.In addition, replace pivotable latch hook 34, slip jam plate can be preferred.Equally, replace hydraulic cylinder 36, can arrange means of threaded drives or only lever retracting spring come for mobile this pivotable or slide lock 34.
The rear portion of hookup 24 is also provided with lifting hole 38.This allows to promote safely article with rope or chain.
All members above of shown hookup are known or traditional in the prior art.Therefore, their purposes and application separately are no longer further discussed.However, it should be understood that these hookups can provide with large-scale size, that is, be sized to and be applicable to large-scale excavator.
Creative feature of the present invention is following public attachment members:
Hookup is suitable for comprising and detects and the communication technology.They are for providing information via display to the excavating-machine operator of driver's cabin, although this information can provide in other places if desired.But the displaying of this information allows state hookup or any connection/separable programming, for example " machining tool connection status " is communicated to driver.Equally, it can also be reported to control system in excavator for self interlocking is provided, can prevent that operating personnel from carrying out undesirable or unsafe operation once complete this self interlocking, until obtain the correct verification of the conditioned disjunction state of hookup by this system.
Can provide and manually surmount control.But, preferably, can avoid manually surmounting and control to guarantee can not occur incorrect use.
(for example provide this interlocking or " without flexible mode (limp modes) ", underspeed, moving-limiting scope or reduce hydraulic power) by preventing or avoid the risky operation of excavator or by minimizing or eliminate misuse chance, improving greatly site safety.
Detection in the embodiment shown and the communication technology comprise selection sensor, and any one in this sensor can provide himself distinctive useful and useful information.First sensor 40 is the sensors that are provided for the first jaw 30.Whether it is positioned at the first jaw 30 for surveying connecting pin.This can be the sensor that activates of proximity transducer, contact or promote or parameter measurement sensor-for example, stress or strain measurement or checkout equipment.Show the throat that it is positioned at the first jaw 30.This is the typical setting position of connecting pin, and therefore this is often optimum position.But, can on the diverse location on this jaw 30, there is more than one sensor, to guarantee to detect any connecting pin in this jaw.This is useful especially (for example,, referring to community's design patent 000452271.0003) in the front jaw with two fillet throat.This is because second sensor compared with in the wall of Rouno Cormer Pregrinding Wheel part of this jaw can also allow to detect larger-diameter connecting pin,, can not be installed to the connecting pin below of the throat of jaw 30 that is.
Be second or deutomala 32 selectable or other sensor 42 is set.In this embodiment, it is arranged in pivotable latch hook 34.This second sensor 42 can be identical with first sensor, and it is also for surveying the existence of the jaw (deutomala 32) that connecting pin is associated at it.By being located in this hook, it only surveys this connecting pin in the time of the joint of this connecting pin by this pivotable latch hook 34.This has prevented the error detector of loose connecting pin.But, if independent sensor has been surveyed the position of this hook, utilize the second sensor of the throat that is positioned at this second jaw can obtain the detection of same degree.
On the other hand, more than one sensor can be set, because different connecting pin can be engaged in the different piece of this jaw, or be incorporated into the different piece of this hook, if especially two connecting pins are from the annex with different center to center pin intervals.
The hookup of this example embodiment also has the 3rd sensor 44, and this sensor is positioned on hydraulic cylinder 36 or hydraulic cylinder 36.It can also be positioned at the supply line of this cylinder.This sensor is used for surveying one of hydraulic pressure or hydraulic cylinder extension state, or both surveys.This kind of data can be used for allowing the even better description of the state of determining hookup.For example, allow to verify the position of pivotable latch hook 34, or can identify hydraulic flow leakage.
Unshowned other sensors can comprise aspect sensor, for determining whether hookup is reversed, or may be to be reversed how many degree.This can contribute to guarantee, when annex 28 is during in dangerous position with respect to hookup, does not start separable programming, that is, if deutomala is opened, it will fall down from hookup.
Other sensor can also be set to identify from annex self, for example, from the information of the transponder in annex, to survey type of attachment or attachment capability, this information can have potential use to central control unit, and this information can be stored in the transponder in annex.
In the embodiment of example, show the different sensors parts in the parts that will be integrated into hookup.Like this, this hookup is customized to the sensor being configured in wherein.However, it should be understood that and can, by repacking mode, sensor be attached to existing hookup or known hookup design.Equally, the electronic installation being associated (for example, seen in the central control unit 46 of the hookup in Fig. 2) can be configured in advance on the framework of hookup or in framework, be become the integration section of hookup 24, or they can be the adapters of repairing after-market.
In the embodiment of example, two sensors 40,42 are first suitable for detecting the existence of connecting pin in their jaw or hooks separately, and the 3rd sensor 44 is surveyed the hydraulic pressure in hydraulic cylinder 36.So data that detect or by discontinuously or be sent to continuously the control electronic installation that is associated for analyzing, or for being passed to other control electronic installation, for example receiver 48 in driver's cabin.So the final state information about hookup is shown to user, or (or in addition) these data work with electronic installation by rights by the control of excavator self, for example, the operation of permission excavator, or carry out suitable " without flexible mode " for surveyed hookup state.There are in this respect a lot of possible operations.For example, for each sensor, display can have the lamp that represents good or bad state, the detected state having represented as green light and red light represents bad detected state, in the time that annex is connected on hookup completely, display shows whole green lights, and in the time detecting annex and be connected to improperly on hookup, shows at least one red light.As long as the red light that indication is such, will probably carry out without flexible mode for excavator.
As mentioned above, should be understood that the sensor of this jaw should be designed to survey multiple different connecting pin, for example, there is the pin of different radii or there is different center to center pin intervals.This is because excavator often uses the annex of number of different types, and needn't often have different pin intervals or different pin radiuses from same manufacturer-so different annexes.In addition, connecting pin can be worn, and the pin interval between two of annex pins can change over time thus.
Will also be understood that; this sensor should be able to be dealt with various harsh ambient conditionss; or at least in various harsh ambient conditionss, protected; hookup is exposed to these ambient conditionss possibly; for example; extreme temperature, be often exposed to lost material (as, stone, rock and mud), roughly process and be immersed in seawater, in fresh water or in mud.Such strengthening sensor technology is known, for example, from as the contiguous field of tire pressure monitoring device.
In a preferred embodiment, the pin sensor the 40, the 42nd in front jaw 30 and deutomala 32, stress and strain detecting sensor.This can survey the existence of connecting pin in jaw, because annex is conventionally very heavy, under the weight of connected annex, this jaw will be exposed to very large load thus.Therefore, such stress or strain transducer can be surveyed by surveying such power the existence of connecting pin.In addition, because these power will act on around this jaw, rather than the ad-hoc location on this jaw (, the contact position between this pin and this jaw) only, in the ability of determining this sensor, to complete its function aspects, the position of this sensor is unimportant.
But, replace stress or strain transducer for this first or second sensor, proximity transducer can be set.They can survey connecting pin approaching in this jaw.
In the embodiment of example, three sensors that illustrate 40,42,44 are connected to central control unit 46 through a cable or wirelessly, this sensor can be wired to central control unit 46, or they can have radio transmitter they self, that be constructed into itself.Therefore this central control unit 46 receives from the detection signal of these sensors and using this information and edits preparation for sending the receiver 48 of driver's cabin 14 to as being interrupted bursty data (databursts).The receiver 48 illustrating is in the driver's cabin of excavator 10, but it can be in other places, and it is connected in display.
Therefore receiver receives the transmission by wireless transmission, thereby this receiver can process sensor data and made display or the control system of excavator is correctly worked.Therefore the present invention allows hookup reliably the hookup status information of himself to be sent to the driver in the driver's cabin of excavator.
Should be understood that the transmission and the receiver technology that are applicable to such transmission have development well in different field, comprise tire pressure monitoring device.In addition, also there is in the prior art good development for coding or the pair system of the right any necessity of such transmission/reception device.Therefore, there is no need further discussion at this.
Replace the wireless transmission for driver's cabin, can transmit data by wired system.This has advantages of at this hookup and can be powered by the power-supply system of excavator self without local power supply-this sensor.But, preferred wireless transmission because they be more easily incorporated in existing excavator and hookup-they need minimized setting, and can make hookup easily remove to keep in repair from excavator.
For to radio transmitter power supply, the power-supply system of carrying with hookup is preferably set on hookup.This can be the battery in central control unit 46 simply.But, generator alternatively can be set on hookup, for producing by recover kinetic energy, required electric energy-in the time that hookup uses, they have stood very large vibrations.
If be provided with battery, other sensor can be set to monitor the energy content of battery.Therefore sensing system can arrange low energy content of battery signal in it transmits, and in the time detecting low energy content of battery state, warns this situation to operating personnel.
Display in driver's cabin or man-machine interface (MMI) (being used to indicate sensor information or hookup status information) can be programmed to provide information by various ways, or provide information with the interactional different modes of control device of itself and excavator.
In a system, this signal can be converted into vision indication, for example lamp or hookup state show, thereby in the time completing some independent steps of connection and separation process, display can be by providing image to indicate to guide operating personnel to connect and separable programming by annex.This is useful, because from can not be always very for example, to information (, the position of pivotable latch hook) in driver's cabin.
Alternatively or additionally, situation about detecting in response to some, for example, annex for example, to the incomplete connection (, only in front jaw) of hookup, and this interface can provide excavator function locking (, " without flexible mode ").Aspect this, can limit or stop specific excavator or digger arm moves, until completed this linker.Alternatively, can reduce motor or hydraulic power, make thus to excavate and handle more difficult.This will stop driver to start or continue the incorrect use of hookup/excavator.
But a preferred feature is, in the time not having connecting pin to be detected, to allow the repertoire of excavator.This is that this lifting hole is through being usually used in the article on lifting chain or rope because hookup is equipped with lifting hole 38 conventionally.This function of stopping using will be very inconvenient.In addition, there is no such freedom moving under not-connected status, handle hookup and excavator and will become more difficult so that the first jaw is aimed to be connected thereto with the first connecting pin of new annex, this is obviously undesirable.
About without flexible mode, such pattern can be low dynamic mode, and wherein choke valve is restricted to maximum 1/4th flows.This can also can be only for hydraulic cylinder for the motor of excavator.
Can also know, can provide the other control that surmounts for the sensor 44 of hydraulic cylinder 36, detect wrong in the situation that thus, hydraulic system oneself will be enough to make to work without flexible mode.
Some other optional features are as follows:
Approve in order to make wireless transmission can be received device 48, transmission can be with unique beacon information coding, and this beacon information can be transmitted to identify transmission sources hookup/sensor certainly.
Transmission may also comprise the details that is connected to the annex on hookup, for example, and type of attachment information.This can be surveyed by the sensor on hookup, and it can read out the information of the radio transceiver on annex.
Duty cycle information, for example used hour or the circulation that completes, can be monitored by control system, this duty cycle information is at hookup place or receiver place.This information can and be transferred into receiver at hookup place record, or at receiver place record, thus when needed, the annex with limited working life can tracked and repairing or replacing.
Equally, the information of other detections can be recorded or transmit, for example, machining tool identifying information, excavator identifying information, unpaired message, instrument applicability information are (for example, instrument ability, type or size), instrument or hookup (for example use information, current loading information) and tracked information (for example GPS locating information), this tracked information is used for allowing automatically transporting follows the trail of or cargo tracking, or from storage information, distinguishes in the future.
From above-mentioned open, therefore, the invention provides the hookup on the digger arm for annex being connected to excavator, this hookup comprises the first jaw, this first jaw is roughly pointing on longitudinal direction with respect to the framework of this hookup, this jaw is for receiving the first connecting pin of annex and having first sensor, this first sensor is for surveying connecting pin existence therein, this hookup also has the second jaw or lock, this second jaw or lock are longitudinally spaced apart with this first jaw, this second jaw is for receiving the second connecting pin of annex, and there is the second sensor, this second sensor is for surveying connecting pin existence therein.As mentioned above, can increase subsequently other features.
