Level sensor is preferably the contactless level sensors such as ultrasound wave level sensor.
Material-level detecting device of the present utility model is particularly suitable for detecting the level of filler material of material surface irregularity.Such as, material-level detecting device of the present utility model may be used for detecting the level of filler material above helical feed rotor, although the existence of helical feed rotor can produce certain impact to material position, local information, but material position, each local information that obtains of this material-level detecting device still can substantially represent (or representing after correction) material surface to thickness information between the loading end of material below helical feed rotor.
Now, if needing the material position, local of certain material position, local information correspondence position, it is only necessary to be modified cutting down the impact that helical feed rotor brings on local material-level measure information.Such as, when the mobile route of the test side of material-level measure sensor is positioned at the surface of helical feed rotor, and in the case of constant with the distance of the loading end of material, material position, local information can be modified obtaining by the way of the diameter of the rotating shaft reducing helical feed rotor in material position, the local information above the helical feed rotor detected the material position, local of this position, although the material position, local obtained in this way does not considers the impact of the blade of helical feed rotor, but expects position the most closely with the true of relevant position.
By this way, if the comprehensive material position of the surface of helical feed rotor to be obtained, can be averaged to obtain this comprehensive material position to the material position, local of each correspondence position obtained.After first material position, each local information averaged can also be obtained middle material position, then by the way of reducing the diameter of the rotating shaft of helical feed rotor, obtain the comprehensive material position directly over helical feed rotor.
If in order to obtain the comprehensive material position in helical feed rotor and neighbouring certain detection range, then by first asking for middle material position, then the comprehensive material position that the mode of correction factor obtains in certain detection range after being modified material position, centre can be used.In some cases, if in the case of the volume of helical feed rotor is the least compared with the inventory of helical feed rotor and neighbouring certain detection range, when the comprehensive material position obtained in certain detection range, the impact of helical feed rotor is the most negligible.
After having obtained comprehensive material position, for utilizing this comprehensive material position to carry out relevant control compared to utilizing material positions, indivedual local information and carrying out same control, result can be controlled more accurately.Certainly, controlling purpose to realize certain, obtain comprehensive material position information and be not likely to be necessary, now comprehensive material position computer is the most not necessarily.Such as, when material-level detecting device of the present utility model is used in the defeated material-distributing system of paver, no matter whether material-level detecting device has comprehensive material position computer, all by the comprehensive material position that material position, each local information controlling the tripper top position that device detects according to material-level detecting device of defeated material-distributing system obtains, the delivery rate of tripper can be controlled, it is also possible to directly the delivery rate of tripper is controlled by material position, each local information controlling the tripper top position that device detects according to material-level detecting device of defeated material-distributing system.Certainly, in the case of material-level detecting device has comprehensive material position computer, the control device of defeated material-distributing system can also directly receive the comprehensive material position of comprehensive material position computer, controls the delivery rate of tripper further according to this comprehensive material position.
The material level detection method of aforesaid material-level detecting device includes: detected material position, the local information of the material corresponding to each detection position by level sensor.In the case of material-level detecting device includes comprehensive material position computer, material level detection method can also include: comprehensive material position computer receives once each local material position information and according to the material acquisition of information comprehensive material position, position, each local once received every first time period.
Wherein, in a specific embodiment, obtain comprehensive material position and may include that material position, each local information once received is modified obtaining material position, each local by detection position according to material position, each local information is corresponding respectively, calculate the meansigma methods of material position, each local as comprehensive material position.The situation that the loading end distance of mobile route and material to be detected which is particularly suited for measurement end changes.
Or, in another particular embodiment of the invention, obtain comprehensive material position and may include that material position, centre, as material position, centre, is modified obtaining comprehensive material position by the meansigma methods calculating material position, each local information once received.The situation that the loading end distance of mobile route and material to be detected which is equally applicable to measurement end changes.
Or, in another specific embodiment, obtain comprehensive material position and may include that the meansigma methods calculating material position, each local information once received is as comprehensive material position.Which is particularly suited for the situation that the mobile route measuring end is constant with the distance holding of the loading end of material to be detected.
This utility model also provides for a kind of paver.Paver includes defeated material-distributing system.Defeated material-distributing system includes tripper, controls device and aforesaid material-level detecting device.Wherein, mobile route is configured such that level sensor all detects material position, the local information of the material of tripper top position in each detection position；Control the delivery rate that device couples with material-level detecting device and tripper respectively and controls tripper according to material position, each local information.
Owing to level sensor is measured when end moves along mobile route the height of materials of tripper top position can be carried out multi-point data acquisition at it, control device according to material position, multiple local information, the delivery rate of tripper to be controlled, therefore can control the inventory of tripper output more accurately, thus be conducive to keeping the stability of material output.
Control device to couple with level sensor to receive material position, each local information and directly control the delivery rate of tripper according to material position, each local information.This setting is i.e. applicable to material-level detecting device and includes the situation of comprehensive material position computer, is also applied for material-level detecting device and does not include the situation of comprehensive material position computer.
In the case of material-level detecting device includes comprehensive material position computer, control device and can also couple with comprehensive material position computer to receive comprehensive material position the delivery rate according to comprehensive Level control tripper.
The defeated sub-material control method of aforesaid paver includes: level sensor detection is corresponding to material position, the local information of the material of each detection position；Control device and control the delivery rate of tripper according to material position, each local information.
In a preferred embodiment, control device receive once each local material position information every the second time period and directly control the delivery rate of tripper according to material position, each local information.
Now, a more specifically preferred implementation is, the delivery rate controlling device control tripper may include that material position, each local information once received is added formation adds up material position information；Relatively add up material position information and the first setting material position information, if adding up material position information to set material position information less than first, controlling tripper and improving delivery rate.If adding up material position information to expect position information more than the first setting, controlling tripper and reducing delivery rate.When adding up material position information and being both not more than nor less than the first setting material position information without changing the delivery rate of tripper.
Carry out the control of delivery rate owing to have employed material position, the local information of more detection position detection, relative to prior art, this preferred implementation can preferably control the stability of outputting material.
Another more specifically preferred implementation is, expect that position information, more than the first setting material position information, replaces the step controlling tripper reduction delivery rate in previous preferred implementation to proceed as follows if added up: relatively near material position, the end local information at the material outlet of defeated material-distributing system and the second setting material position information in the information of material position, each local, if material position, end local information controls tripper more than the second setting material position information and reduces delivery rate, if material position, end local information controls tripper less than the second setting material position information improves delivery rate.When material position, end local information had both been not more than and had set material position information nor less than second without changing the delivery rate of tripper.Wherein, add up material position information and be both not more than the situation setting material position information nor less than first, the operation identical more than the first setting material position information with adding up material position information can be made；Can also directly return and receive each local material position information and calculate the step adding up material position information.
For this embodiment is compared to previous preferred implementation, carry out dual judgement and control owing to have employed the first setting material position information and the second setting material position information, therefore can better control over the stability of outputting material than previous preferred implementation.
Wherein, the first setting material position information can be a numerical value, now, adds up and expects that position information had both no more than set the situation expecting that position information is equal to this numerical value as adding up material position information nor less than first.In the case of the first setting material position information is a numerical value, in order to prevent the delivery rate of tripper from regulating the most frequently, by suitably controlling the duration of the second time period, the regulation frequency of tripper can be controlled.
First setting material position information can also be a numerical range, now, add up the minimum that material position information refers to add up material position information less than this numerical range less than the first setting material position information, and add up the peak that material position information refers to add up material position information more than this numerical range more than the first setting material position information, add up material position information be both not more than set nor less than first material position information referred to add up material position information less than or equal to the peak of this numerical range the minimum more than or equal to this numerical range.In the case of first setting material position information is a numerical range, the duration of the second time period can not be controlled because considering the regulating frequency of the delivery rate of tripper, such that it is able to control the delivery rate of tripper more timely and effectively, thus better control over the stability of outputting material.
Second setting material position information can also be a numerical value or a numerical range, and related content can be according to the related description above setting material position information to first.Such as, when the second setting material position information is a numerical range, material position, end local information refers to material position, the end local information minimum less than this numerical range less than the first setting material position information, and material position, end local information refers to material position, the end local information peak more than this numerical range more than the first setting material position information.
