Description

一种料仓物料成分的检测方法及系统Method and system for detecting material composition in a silo

技术领域technical field

本发明涉及智能控制技术领域,尤其涉及一种料仓物料成分的检测方法及 系统。The invention relates to the technical field of intelligent control, and in particular, to a method and system for detecting material components in a silo.

背景技术Background technique

在冶炼领域,各种矿物的混合比例、含水量、烧结过程中燃料及灰石配比 等,对最终产品的影响程度都非常高,通常需要对原料的成分比例进行严格控 制。In the field of smelting, the mixing ratio of various minerals, water content, fuel and limestone ratio in the sintering process, etc., have a very high degree of influence on the final product, and usually it is necessary to strictly control the composition ratio of raw materials.

目前都只是简单的使用最新的成分检测值进行配料计算,由于原料仓具有 一定的仓储能力,正在使用的原料批次成分未必就对应最新的成分检测值。因 此,当上述情况发生时,造成实际原料成分和配料计算使用成分出现偏差,进 而直接影响实际的原料配比。配料计算的方法基本相同,但是在如何精确定位 混匀矿仓中存储的混匀矿因为批次差异和含水量差异导致的最终成分波动的问 题一直是难以解决的问题。At present, all the ingredients are simply calculated using the latest component detection values. Since the raw material warehouse has a certain storage capacity, the ingredients of the batches of raw materials being used may not correspond to the latest component detection values. Therefore, when the above situation occurs, the actual raw material composition and the ingredients used in the calculation of the ingredients are deviated, which in turn directly affects the actual raw material ratio. The method of batching calculation is basically the same, but how to accurately locate the final composition of the mixed ore stored in the mixing silo due to batch differences and water content differences has always been a difficult problem to solve.

目前一般是在料仓的出料口采用人工方式取样、化验原料成分,每班取样 一到两次,再用于配料配比计算,该方法只能用于原料较稳定的情况;另一种 方法是在配料后的混合机出口大皮带上设置在线成分分析仪综合检测原料,但 此时只能用于分析原料成分尤其是碱度等指标是否符合配料的要求,无法判断 哪一个料仓原料成分波动需要调整,从而难以实现反馈控制。At present, the raw materials are generally sampled and tested manually at the discharge port of the silo. The samples are taken once or twice per shift, and then used for the calculation of the proportion of ingredients. This method can only be used when the raw materials are relatively stable; another The method is to set an online composition analyzer on the large belt at the outlet of the mixer after batching to comprehensively detect the raw materials, but at this time, it can only be used to analyze whether the raw material composition, especially the alkalinity and other indicators meet the requirements of the batching, and it is impossible to judge which silo raw material is used. Compositional fluctuations require adjustment, making feedback control difficult.

具体实施方式Detailed ways

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部 的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

下面首先结合相关附图来举例介绍下本申请实施例的方案会应用到的料仓 仓位系统。First, the silo storage system to which the solutions of the embodiments of the present application will be applied will be described by way of example in conjunction with the relevant drawings.

如图1所示,为本发明一个实施例中料仓仓位控制方法的料仓仓位控制系 统,其中1为成分分析仪,2为入料皮带,3为入料皮带秤,4为卸料装置,5 为出料皮带,6为出料皮带秤。实际生产过程中,卸料小车可以沿着滑轨左右 移动至需要加料的料仓位置,卸料小车两端都可以下料,但同一时间只能对一 个料仓下料。As shown in Figure 1, it is a silo position control system of a silo position control method in an embodiment of the present invention, wherein 1 is a component analyzer, 2 is a feeding belt, 3 is a feeding belt scale, and 4 is a discharge device , 5 is the discharge belt, 6 is the discharge belt scale. In the actual production process, the unloading trolley can move left and right along the slide rail to the position of the silo that needs to be fed. Both ends of the unloading trolley can unload material, but only one silo can be unloaded at the same time.

图1的具体实例中一共示出的例子为8个料仓,物料经入料皮带2送入时, 入料皮带秤3会记录物料的瞬时料量。卸料装置4根据入料模式不同可以是犁 式卸料斗或卸料小车,决定物料进入哪个料仓1中,同一时刻只有一个料仓1 入料。当某个料仓1需要出料时,物料由料仓1下料到出料皮带秤6,出料皮 带秤6会记录该料仓的瞬时出料量。A total of 8 silos are shown in the specific example of FIG. 1 . When the material is fed through the feeding belt 2 , the feeding belt scale 3 will record the instantaneous amount of the material. The unloading device 4 can be a plough-type unloading hopper or a unloading trolley according to different feeding modes, which determines which silo 1 the material enters, and only one silo 1 is fed at the same time. When a certain silo 1 needs to be discharged, the material is unloaded from the silo 1 to the discharge belt scale 6, and the discharge belt scale 6 will record the instantaneous discharge amount of the silo.

如图2所示,本发明的第一实施例中提供的料仓物料成分的检测方法,包 括步骤:As shown in Figure 2, the detection method of the silo material composition provided in the first embodiment of the present invention comprises the steps:

S1,按照预设的频率或者实时获取K个料仓进行入料输送的入料皮带秤处 的成分测量仪侦测到的当前时刻t时的入仓物料的成分含量集αk(t),以获得入 仓成分队列;其中,k为所述料仓的编号k∈[1,K],每个所述入仓物料的成分含 量集αk(t)包括S种不同成分的含量

Figure BDA0003621847160000051
s∈[1,S]。S1, according to the preset frequency or real-time acquisition of the composition measuring instrument at the feeding belt scale for feeding and conveying the K silos, the composition content set α k (t) of the incoming material at the current time t detected, In order to obtain the silo component queue; wherein, k is the number of the silo k∈[1,K], and the component content set α k (t) of each of the siloed materials includes the content of S different components
Figure BDA0003621847160000051
s∈[1,S].

例如,在钢铁冶炼行业,成分含量集αk(t)可以包括

Figure BDA0003621847160000061
For example, in the steel smelting industry, the component content set α k (t) may include
Figure BDA0003621847160000061

,分别表示全铁成分含量、水分率、二氧化硅含量、氧化钙含量、氧化镁含量、 三氧化二铝含量、硫的含量。具体来说,成分含量集αk(t)中的成分组成可以根 据现场工艺需求自行决定。, respectively represent the total iron content, moisture content, silica content, calcium oxide content, magnesium oxide content, aluminum trioxide content, and sulfur content. Specifically, the component composition in the component content set α k (t) can be determined by itself according to the on-site process requirements.

S2,根据预设的时间间隔构建料仓虚拟分层,将所述料仓内的堆积物料分 为n个料仓虚拟分层Nx,x∈[1,n],并根据公式

Figure BDA0003621847160000062
计算第k 个所述料仓的所述料仓虚拟分层Nx的第s种成分的含量
Figure BDA0003621847160000063
所述t1与t2之 间的时间差为所述预设的时间间隔。S2, build a virtual silo layer according to a preset time interval, divide the accumulated materials in the silo into n virtual silo layers N x , x∈[1,n], and according to the formula
Figure BDA0003621847160000062
Calculate the content of the s-th component of the virtual layer N x of the silo of the k-th silo
Figure BDA0003621847160000063
The time difference between t 1 and t 2 is the preset time interval.

S3,根据入料时间与出料时间的对应关系,获取当前出料的物料与所述料 仓虚拟分层Nx的时间关系,从而获得当前出料的成分数据。S3, according to the corresponding relationship between the feeding time and the discharging time, obtain the time relationship between the material currently discharged and the virtual layer Nx of the silo, so as to obtain the component data of the current discharging.

具体的,请一并结合图3和图4,在时间轴上节点t1和t2内设置时间窗,时 间窗大小由实际生产需求决定,其最小值不小于成分分析仪的采样周期。时间 窗在入仓料量队列上首尾相接的沿时间轴滑动,所取的一段时间t1到t2内的入仓 料量的累计值和入仓物料主要成分向量的均值作为一个分块Nx,由此可构成料 仓虚拟分层Nx,其中料仓每个虚拟分层Nx在时间上对应时间窗所获取的入仓 物料数据,并且满足FIFO先进先出原则。对于每个料仓,只考虑其有效时间 内的入料情况,数据队列则是有效时间内的入料队列依据时间顺序串接而成。Specifically, please refer to Figure 3 and Figure 4 together to set a time window within nodes t 1 and t 2 on the time axis. The size of the time window is determined by the actual production demand, and its minimum value is not less than the sampling period of the component analyzer. The time window slides along the time axis end-to-end on the warehousing quantity queue, and the accumulated value of the warehousing quantity and the mean value of the main component vector of the warehousing material within a period of time t 1 to t 2 are taken as a block N x , which can constitute a virtual silo N x , wherein each virtual silo N x corresponds to the incoming material data obtained by the time window in time, and satisfies the FIFO first-in-first-out principle. For each silo, only the feeding situation within its valid time is considered, and the data queue is formed by concatenating the feeding queues within the valid time in chronological order.

因此,进一步地,每个虚拟分层Nx的物料量表示为在t1和t2时间内,第k 个料仓入料量,即,

Figure BDA0003621847160000064
Therefore, further, the material quantity of each virtual layer Nx is expressed as the feeding quantity of the kth silo in the time t1 and t2 , that is,

具体来说,测量每个虚拟分层Nx的所述物料量的步骤包括:Specifically, the step of measuring the material amount of each virtual layer Nx includes:

S12,按照预设的频率或者实时获取K个料仓进行入料输送的入料皮带秤 侦测到的当前时刻t时的入仓物料量wk(t);S12, according to a preset frequency or real-time acquisition of the incoming material amount w k (t) at the current time t detected by the feeding belt scale for feeding and conveying the K silos;

S22,根据公式

Figure BDA0003621847160000071
计算第k 个所述料仓的所述料仓虚拟分层Nx的物料量W(Nx)。S22, according to the formula
Figure BDA0003621847160000071
Calculate the material quantity W(N x ) of the virtual layer N x of the silo of the k-th silo.

可以理解的是,N个所述料仓在同一时刻只有一个所述料仓入料,第k个 所述料仓的入仓物料的成分含量集记录为Sk(t)αk(t),Sk(t)=为0表示在当前时刻 t第k个料仓入料状态关闭,Sk(t)为1时表示当前时刻第k个料仓入料状态开启。 可以理解的是,由于同一时刻只有一个料仓入料,依据卸料装置4的操作时间、 入料皮带秤3会记录物料的瞬时料量的时间,以及物料从入料皮带秤3运动到 对应料仓的时间,可以计算出每个时刻t的入料瞬时物料量。另外,需要说明 的是当前料仓在入料时,其他料仓的入料瞬时物料量为0。It can be understood that only one of the N silos is fed at the same time, and the component content set of the incoming material of the kth silo is recorded as S k (t)α k (t) , Sk (t)=0 means that the feeding state of the kth silo at the current time t is closed, and when Sk (t) is 1, it means that the feeding state of the kth silo at the current time is open. It can be understood that since there is only one silo feeding material at the same time, according to the operation time of the unloading device 4, the time when the feeding belt scale 3 records the instantaneous amount of the material, and the movement of the material from the feeding belt scale 3 to the corresponding The time of the silo can be calculated to calculate the instantaneous amount of material fed at each time t. In addition, it should be noted that when the current silo is feeding, the instantaneous material amount of other silo feeding is 0.

其中,入料皮带秤所得数据为离散数据时,在实际应用中需要采用密集采 样的方式来代替积分过程,第k个料仓入料量积分可以转换为密集采样求和。 此时节点t1和t2应为有效下料时间(即Sk(t)为1时的时间),且应对每个料仓构 建一个独立的物料质量队列,每个料仓的一段有效下料时间即产生一段物料质 量队列,最终每个料仓的队列应该是该料仓各有效下料时间物料质量队列片段 依据时间顺序串联。f1为所述入料皮带秤的采样频率。Among them, when the data obtained by the feeding belt scale is discrete data, in practical applications, it is necessary to use dense sampling to replace the integration process. At this time, the nodes t 1 and t 2 should be the effective unloading time (that is, the time when S k (t) is 1), and an independent material quality queue should be constructed for each silo. The material quality queue is generated by the material time, and finally the queue of each silo should be the material quality queue segments of the effective unloading time of the silo, which are connected in series according to the time sequence. f 1 is the sampling frequency of the feeding belt scale.

Wherein, the content of the sth component of the virtual layer Nx of the silo of the kth silo
Figure BDA0003621847160000072

具体来说,根据所述入料皮带秤测量得到的离散数据,f1为所述入料皮带 秤的采样频率,在时间轴上节点t1和t2内设置的时间窗内,成分检测仪所得数据 为离散数据,此时t1和t2应为有效下料时间(即Sk(t)为1时的时间),且应对每 个料仓构建一个独立的物料质量队列,每个料仓的一段有效下料时间即产生一 段物料质量队列,最终每个料仓的队列应该是该料仓各有效下料时间物料质量 队列片段依据时间顺序串联。Specifically, according to the discrete data measured by the feeding belt scale, f 1 is the sampling frequency of the feeding belt scale, and within the time window set in the nodes t 1 and t 2 on the time axis, the composition detector The obtained data is discrete data. At this time, t 1 and t 2 should be the effective unloading time (that is, the time when Sk (t) is 1), and an independent material quality queue should be constructed for each silo. A period of effective unloading time of the silo will generate a period of material quality queue, and finally the queue of each silo should be the material quality queue segments of each effective unloading time of the silo connected in series according to the time sequence.

进一步地,所述S中不同成分包括水、以及有效物料组份。Further, the different components in the S include water and effective material components.

进一步地,所述预设的时间间隔不小于所述采样周期f。Further, the preset time interval is not less than the sampling period f.
