Abstract
Description
Claims (6)
- Concrete vibrating significant depth and effective time method for supervising, it is characterized in that, comprise the following steps:Step 1, after vibrating spear inserts concrete, system starts timing, and to server end, sends the monitor data that vibrates at regular intervals, until vibrating spear is extracted after concrete completely, stops timing, and sends to server end the instruction of having vibrated;Step 2, server end receive the instruction of having vibrated, and according to vibrate monitor data and the command calculations of having vibrated that receive the before degree of depth of effectively vibrating;Step 3, server end calculate effective vibrating time, insertion time and the time of extracting;Step 4, server end according to the degree of depth of effectively vibrating calculating, effectively vibrating time, insertion time and the time of extracting respectively with the technological specification prestoring in depth capacity, maximum vibrating time, maximum insertion time and the maximum time of extracting compare, whether judgement is vibrated qualified, and judged result is presented to user.
- Concrete vibrating significant depth as claimed in claim 1 and effective time method for supervising, it is characterized in that, in step 1, described in the monitor data that vibrates at least comprise the actual degree of depth of vibrating.
- Concrete vibrating significant depth as claimed in claim 2 and effective time method for supervising, it is characterized in that, described in vibrate monitor data also comprise send monitor data time, vibrate insert angle, the orientation angles of vibrating, vibrate point coordinate position and vibrator numbering.
- Concrete vibrating significant depth as described in claim 1 or 2 or 3 and effective time method for supervising, it is characterized in that, in step 1, described certain hour is designated as Δ t;In step 2, effectively the vibrate method of the degree of depth of described calculating is: the degree of depth of vibrating that concrete is total is designated as h, and this degree of depth of vibrating is divided into i section, be designated as respectively h1, h2, hi, h=h1+h2+ ... + hi, at each, vibrate in degree of depth section, server end all can receive the Nj bar monitor data that vibrates, vibrating time tj=Nj * Δ t of the degree of depth section of vibrating arbitrarily, total duration t=t1+t2+ that vibrates ... + ti, the quantity of the monitor data that vibrates sending in the whole process of vibrating is N=N1+N2+ ... + Ni, whole, vibrate in process, the computing formula of the significant depth of vibrating D is:D=(h1×P1+h2×P2+…+hi×Pi)=(h1×t1/T+h2×t2/T+…+hi×ti/T)=(h1×N1+h2×N2+…+hi×Ni)×△t/T=(h1×N1+h2×N2+…+hi×Ni)/(N1+N2+…+Ni)Wherein, Pj=Nj/N, refers to the j section weighing factor of the degree of depth to the whole significant depth of vibrating that vibrate, and i is positive integer, and j is the positive integer that is less than or equal to i.
- Concrete vibrating significant depth as claimed in claim 4 and effective time method for supervising, it is characterized in that, in step 3, calculate effective vibrating time, the method of insertion time and the time of extracting is: the monitor data that vibrates sending for the first time, server end is thought the data of vibrating under insertion state, when sending the monitor data that vibrates for the second time, start, server end receives the monitor data that vibrates at every turn and all judges the degree of depth of once vibrating before whether this degree of depth of vibrating is greater than, if the degree of depth of once vibrating before being greater than is judged to be insertion state, otherwise for extracting state, when being insertion state, and the degree of depth of vibrating is less than while vibrating significant depth, the monitor data that vibrates now receiving is insertion process monitor data, when for extracting state, and the degree of depth of vibrating is less than while vibrating significant depth, and the monitor data that vibrates now receiving is withdrawal process monitor data, when the degree of depth of vibrating is greater than while vibrating significant depth, the monitor data that vibrates now receiving is for the process monitoring data of effectively vibrating, add up respectively insertion process monitor data number M 1, withdrawal process monitor data number M -1with the process monitoring data number M that effectively vibrates 0, calculate effective vibrating time K, effectively insert time K 1and effectively extract time K -1, its computing method are respectively:K=M×△tK 1=M 1×△tK -1=M -1×△t。
- Concrete vibrating significant depth as claimed in claim 5 and effective time method for supervising, it is characterized in that, in step 4, judgement vibrates whether qualified method is:By the depth D of effectively vibrating, compare with the depth capacity Hs in the technological specification prestoring, when D >=Hs, be judged to be the degree of depth of vibrating qualified, when D<Hs, be judged to be the degree of depth of vibrating defective;By the maximum vibrating time T in effective vibrating time K and the technological specification that prestores scompare, as K>=T stime, be judged to be vibrating time qualified, work as K<T stime, be judged to be vibrating time defective;By effective insertion time K 1insert time T with the maximum in the technological specification prestoring dcompare, work as K 1>=T dtime, be judged to be the insertion time qualified, work as K 1<T dtime, be judged to be insertion too fast;By effectively extracting time K -1extract time T with the maximum in the technological specification prestoring ucompare, work as K -1>=T utime, be judged to be the time of extracting qualified, work as K -1<T utime, be judged to be extract too fast.
