[concrete mixer truck]
After receiving concrete, concrete mixer truck to specifying the building site, may occur the stolen problem of material with concrete transportation during this, thereby brings unnecessary dispute for building site and mixing plant.Therefore, usually be provided with the material burglary-resisting system on the concrete mixer truck, to avoid occuring problems.
As shown in Figures 2 and 3, the invention provides a kind of material burglary-resisting system of concrete mixer truck, in this material burglary-resisting system, the groundwork principle is: after discharging occurs concrete mixer truck 500, whether be the target location by monitoring its current location, judge whether material is stolen.Namely, this material burglary-resisting system comprises the loading and unloading material monitoring system 204 of the loading and unloading material state of the location monitoring system 205 of current location of monitored concrete trucd mixer 500 and monitored concrete trucd mixer 500, when second controller 202 is judged concrete mixer truck generation discharging, and when the current location of the concrete mixer truck 500 that location monitoring system 205 is monitored and target location are different, judge that the material of concrete mixer truck 500 is stolen.Wherein, location monitoring system 205 can be GPS equipment, but the GPS terminal of namely in concrete mixer truck 500 monitoring position being installed.
In technique scheme, the technology of location monitoring system 205 is comparatively ripe, does not do too much at this and gives unnecessary details, and wherein, how to judge that the discharging state of concrete mixer truck 500 becomes key.Therefore, the invention provides a kind of loading and unloading material monitoring system 204 of loading and unloading material method for supervising and this method for supervising of realization of concrete mixer truck, wherein, concrete mixer truck comprises mixing drum and drives the hydraulic system of this mixing drum, loading and unloading material monitoring system 204 provided by the invention comprises the first checkout gear 201 and the second controller 202 of mutual electrical connection, loading and unloading material method for supervising provided by the invention comprises foresee steps, detecting step and determining step, in foresee steps, at second controller 202 interior default oil pressure preset values, the initial oil pressure value of hydraulic system when this oil pressure preset value is concrete mixer truck 500 carrying primary quantity concrete, this primary quantity concrete can be the amount of concrete behind the blowing of receiving concrete mixing plant 600 in concrete mixer truck 500, also can be any amount of concrete before loading and unloading material, initial oil pressure value then be that hydraulic system can drive the oil pressure value that concrete mixing drum 501 rotations of primary quantity are housed.In detecting step, use the first checkout gear 201 to detect the oil pressure instantaneous value of hydraulic system and this oil pressure instantaneous value is fed back to second controller 202, and in determining step, second controller 202 compares this oil pressure instantaneous value and oil pressure preset value, when oil pressure instantaneous value during less than this oil pressure preset value, second controller 202 is judged concrete mixer truck generation discharging, when oil pressure instantaneous value during greater than the oil pressure preset value, then second controller 202 can judge that concrete mixer truck 500 feeds.
In the technical program, be different from and pass through to detect the mode of mixing drum rotating or the mode of discharging lever position moving position in the prior art, the present invention can directly learn the variation of the amount of concrete of mixing drum 501 inside by the mode of the oil pressure value of detection hydraulic system.This is because the amount of concrete in the oil pressure of hydraulic system and the mixing drum 501 is proportional, and when namely this oil pressure remained unchanged, the expression amount of concrete did not change, and can judge that discharging or charging do not occur concrete mixer truck this moment.And when oil pressure continue to lower, then expression judged that the concrete in the mixing drum 501 is fewer and feweri, can judge that dischargings occur concrete mixer truck 500, can judge then that on the contrary concrete mixer truck 500 feeds.
Need to prove at this, in material burglary-resisting system provided by the invention, only need to use the discharging monitor portion in the loading and unloading material monitoring system that the invention described above provides, its charging part then can be used for above-mentioned concrete mixing plant 600 to the control feeding system of concrete mixer truck 500 blowings, can learn the state of concrete mixer truck in charging process.The below describes in detail.
Wherein, in order to make detection convenient, preferably, the first checkout gear 201 detects the oil pressure instantaneous value of the hydraulic pump output in the hydraulic systems.Namely the first checkout gear 201 can be the pressure sensor on the pressure-control valve that is installed in hydraulic pump.Certainly, those skilled in the art the thinkable mode that other detect the hydraulic system oil pressure drop in protection scope of the present invention equally.For example pressure sensor can be installed in the hydraulic motor of driving mixing drum 501 rotations or other positions of hydraulic system, should drop in protection scope of the present invention equally for this type of change.
In addition, in the material burglary-resisting system, in order farthest to utilize concrete mixer truck, above-mentioned oil pressure preset value comprises the first oil pressure preset value, and this first oil pressure preset value is the oil pressure value when concrete mixer truck 500 full load hydraulic systems.Namely when oil pressure instantaneous value during less than this first oil pressure preset value, can judge that then dischargings occur concrete mixer truck 500.And in the control feeding system, when the oil pressure instantaneous value equals this first oil pressure preset value, can judge that concrete mixer truck 500 charging finishes, and can control concrete mixing plant and stop blowing this moment, material is excessive to cause waste to avoid.
For material burglary-resisting system provided by the invention, the accuracy impact that its material is antitheft and relation and the interests in building site are if it is equally very large on user's impact that wrong report occurs.To this, what need the emphasis explanation is that concrete mixer truck 500 in transportation the burst accidents such as bad car occurs sometimes, needs this moment promptly mixing drum 501 interior concrete are all drawn off, and solidifies in mixing drum 501 to prevent concrete.Discharging equally can occur in non-target location in this moment, and to be judged as material stolen if this moment will this discharging, will cause wrong report, if accordingly the driver is checked and rated, will cause inequitable evaluation to the driver.
Therefore, for fear of this situation, oil pressure preset value in the second controller 202 also comprises the second oil pressure preset value, this the second oil pressure preset value is the oil pressure value of hydraulic system when concrete mixer truck 500 zero load, namely when not having concrete in the mixing drum 501, the oil pressure value of oil hydraulic system when driving mixing drum 501 and rotating.Therefore, when the oil pressure instantaneous value of the first checkout gear detection equaled this second oil pressure value, second controller 202 judgement concrete mixer truck 500 materials were unsnatched.At this moment, it is stolen that material burglary-resisting system provided by the invention can judge that material does not occur concrete mixer truck 500, but urgent discharging occurs.This is owing to when the generation material is stolen, whole concrete can not be drawn off and steal, and at this moment is generally the situation that urgent discharging occurs.Thereby the accuracy of material burglary-resisting system provided by the invention is higher, and practicality is stronger.
In technique scheme, second controller 202 can be installed in the customer center at user place, the information that the first checkout gear 201 detects can return to the second controller 202 of customer center by wireless communication mode (such as GPRS module etc.), thereby judges whether concrete mixer truck 500 discharging occurs.In order further to promote the practicality of material burglary-resisting system provided by the invention, preferably, the material burglary-resisting system also comprises the 3rd controller 206 that is electrically connected with location monitoring system 205 and loading and unloading material monitoring system 204 respectively, and it is stolen to judge by the 3rd controller 206 whether concrete mixer truck 500 material occurs, namely the 3rd controller 206 is installed in customer center equally, and the monitored results of binding site monitoring system 205 and loading and unloading material monitoring system 204 is carried out automatic decision.Wherein preferably, the material burglary-resisting system also can comprise the warning device 207 by 206 controls of the 3rd controller.
In the specific works process, when loading and unloading material monitoring system 204 judged that discharging occurs concrete mixer truck 500 and material is not unsnatched, the 3rd controller 206 judged that discharging occurs concrete mixer truck 500.At this moment, the 3rd controller can be controlled warning device 207 and report to the police, and the middle record of the stolen result of this material can being uploaded onto the server, with as the estimation standard to the driver.In addition, when loading and unloading material monitoring system 204 judges that concrete mixer truck 500 finds that discharging and material are unsnatched, when namely urgent discharging occuring, as shown in Figure 3, the 3rd controller 206 need not controlled warning device 207 and report to the police, but can only carry out record, in order to further determining reason with the driver.Certainly control this moment the 3rd its 206 also can control warning device 207 and report to the police, note with the personnel that cause customer center, but this alarm logging can be cancelled this moment, and can not estimate the driver as the stolen record of material.For these set-up modes, all should drop in protection scope of the present invention.Wherein, this warning device 207 can be buzzer well known in the art, warning lamp etc., also can be controlled in addition in the display screen of customer center to carry out literal prompting etc.All should drop in protection scope of the present invention for this type of set-up mode.
In addition, for so that judged result is more accurate, this the first oil pressure preset value and the second oil pressure preset value all can be set to a value range, namely can determine a rational oil pressure value scope by those skilled in the art's test of many times, by using this oil pressure value scope, can effectively avoid hydraulic system itself that fluctuation occurs and the inaccurate problem of the unusual judgement that brings of oil pressure value that causes.
Except the optimal way of the invention described above, as urgent discharging occurs, the driver can report the developments to customer center usually, and also can as further determining whether the stolen foundation of material occur with its judged result in conjunction with above-mentioned loading and unloading material monitoring system 204 this moment.Therefore, it is stolen that material burglary-resisting system provided by the invention can judge more exactly whether concrete mixer truck 500 material occurs, so that use the practicality of concrete mixer truck of this material burglary-resisting system stronger.
[concrete mixer truck and concrete pumping equipment]
