In prior art, some automatic selling cabinet uses the single-point type scale pan, i.e. uses on each layer of shelf same The single-point type scale pan.However the thickness of the single-point type scale pan is generally higher than 5cm, occupies laying for goods space, since weighing system exists Angular difference, dog is not accurate for weighing precision, and can only can judge the gross weight of all items weight on the scale pan, can not accurately determine The specific location of the position changed article of state；In addition, the single-point type scale pan be routed in cabinet it is complex, and article identify It cannot be with the presence of same dead weight cargo above the Shi Yaoqiu same layer scale pan.

Fig. 1 shows the flow chart of the Item Information inventory acquisition methods according to one embodiment of the disclosure.As shown in Figure 1, The Item Information inventory acquisition methods include the following steps S101-S103:

In step s101, multiple weight change datas are obtained；Wherein, the weight change data is respectively on supporter Place or take away the corresponding weight change data of multiple predeterminated positions when article；

In step s 102, the changed object of article condition on the supporter is determined according to the weight change data Grade is set and the article condition of the article position；

In step s 103, the supporter is updated according to the article condition of the article position and the article position On Item Information inventory.

With the development of internet technology, scientific and technological progress, in order to facilitate the use of people, unmanned supermarket, nobody is sold Machine, unmanned shelf come into being, and realize complete autonomous shopping.But since nobody sells in environment also nobody purchase for user The behavior of buying is supervised, and therefore, often be will appear the cargo other than buying behavior and is reduced situation, and then businessman is caused to manage Loss.Industry is sold for nobody, goods damage situation is the indispensable core data of service operation, is the assessment of point quantity of operation One of most important parameter, while being also the important evidence of point migration efficiency decision.Currently, the control of goods damage data mainly according to Rely in periodically manually making an inventory, but this mode takes a long time, real-time is poor, and human cost is higher.

In view of drawbacks described above, in this embodiment, a kind of Item Information inventory acquisition methods are proposed, this method is first The multiple weight change datas for first obtaining multiple predetermined positions on supporter, determine according to multiple weight change datas later The article condition of the changed article position of article condition and the article position on supporter, the article condition include Article position is placed with the first state of article and article position does not place article quilt in the second state namely supporter of article Take or place specific location up away, be finally removed further according to Item Information inventory original on supporter and article or The article position that person is placed up updates the Item Information inventory on supporter.Above-mentioned side is proposed to obtain by the embodiment of the present disclosure Method can judge automatically the variation of the article condition on supporter by the weight change of predetermined positions multiple on supporter, and And the specific location that the article of article condition variation occurs can be positioned, and then supporter can be updated according to the specific location On Item Information inventory.

In the present embodiment, supporter can be the plate with regular shape, such as round, rectangle or square etc. Plate.Multiple predeterminated positions can be any position on supporter, and multiple predeterminated positions include at least two different positions It sets.The variation of multiple weight datas can be the pressure change data that multiple predeterminated positions generate namely weight changes front and back The pressure absolute value of the difference experienced at multiple predeterminated positions.In one embodiment, multiple weight data variations can lead to The pressure sensor being arranged in below supporter is crossed to obtain.Certainly, in other embodiments, can also obtain by other means Take the weight change data of supporter predetermined position, for example, risen by the multiple predetermined positions of supporter or moved down height, And the size relation of supported underneath elastic force determines weight change data.

Below by taking pressure sensor as an example, illustrate the implementation process of the present embodiment above method, it should be noted that It is, the present disclosure is not limited to using pressure sensor to obtain weight data, with no restrictions to this disclosure.

The weight change that mode obtains multiple predetermined positions is obtained by the way that multiple pressure sensors are arranged below supporter Data.When article is placed on supporter or article is removed from supporter, pressure sensor is able to detect that weight Delta data, detected weight change data can be used to determine that article condition on supporter changes to obtain article Specific location.Weight change data includes the delta data that weight increases additive weight reduction, i.e. weight increases how many or again Amount reduces how many data.Multiple predeterminated positions on supporter include at least two positions, and at least two position is divided It Wei Yu not the opposite both sides of supporter.For example, at least two position can be located at mutually flat when supporter bit length is rectangular In capable length sides or the depth side being parallel to each other.

In the present embodiment, article condition includes the first state that article is placed on supporter or article not in glove The second state on frame.Article condition changes including from first state to the second state, or from the second state to first State when state change or article when the variation of state namely article are placed to supporter are removed from supporter Variation.When article is placed to supporter, the weight that multiple predetermined positions are born, which will increase or reduce, (specifically to be increased also It is to reduce to depend on article position), and finally generate the increased delta data of weight change summation of multiple predetermined positions；And When article is removed from supporter, the weight that multiple predetermined positions are born, which can reduce or increase, (specifically to be increased or subtracts Article position is depended on less), and finally generate the delta data of the weight change summation reduction of multiple predetermined positions.For setting Article in rack, multiple differences of the predetermined position weight change data based on article position and it is different, but no matter article It is placed on the where of supporter, the summation of the weight change of multiple predetermined positions is equal to the total weight of the article, therefore, can To become by the relationship for presetting multiple predetermined position weight change datas and article position, and then in article condition When change, it is determined that after multiple predetermined position weight change datas, determine article on supporter according to preset above-mentioned relation Position.

It, can be with the Item Information inventory on pre-recorded supporter in the initial stage in the present embodiment.There is object on supporter When product state changes, Item Information inventory can be updated according to identified article position.Item Information inventory can wrap Include article mark, Item Weight, article position and/or other relevant informations.It, can be from Item Information inventory after article is removed The corresponding record of middle deletion article, and after article is placed on supporter, the article can be supplemented in Item Information inventory Corresponding record.

By disclosure above-described embodiment, the article condition variation on supporter can be judged automatically, and position generation object The specific location of the article of product state change, and without relying on artificial monitoring or self-service/nobody sells selling in environment Information, the case where capable of finding the variation of improper article condition in time, (such as nobody sold the goods in environment other than buying behavior Object reduces situation), and then the Item Information inventory on supporter that can timely update.The disclosure can be applied to it is self-service/nobody On vending machine, information of being sold or replenished with automatic acquisition can save resource, and accuracy rate is higher, for article on supporter Put and do not specially require, adaptation range is wider.

In an optional implementation of the present embodiment, the step S101 obtains multiple weight change datas Step further includes steps of

In the optional implementation, the weight change data of multiple predetermined positions, which utilizes, to be arranged in below supporter Weight sensor obtains, and weight sensor includes but is not limited to pressure sensor.Multiple pressure can be set below supporter Sensor is arranged at pressure sensor at each pressure sensor for the supporting point of the supporting point of supporter namely supporter. Pressure sensor can detecte to the direction of the pressure and pressure born.Pressure sensor can be two or two with On.If being only provided with two pressure sensors, the one-dimensional space coordinate of article can be determined based on lever principle, and if Provided with more than two pressure sensors, then it is based on lever principle, article 2-d spatial coordinate can be obtained.

After placing an article in the present embodiment, on supporter, placement location difference and pressure sensor based on article Locating different location, different pressure sensors can detect different pressure changes, based on lever principle it is found that some pressures Force snesor detects downward bigger pressure, and some pressure sensors then detect upward bigger pulling force.And supporter On take an article away after, the position being removed based on article is different and pressure sensor locating for different location, different pressures Force snesor can detect the pressure change of different directions, and some pressure sensors are detected before being removed compared with article and are pressed downward Power reduces, and some pressure sensors detect that upward pulling force is reduced before being removed compared with article, can detect upward bear Pressure provided with two pressure sensors below supporter when article is placed among two pressure sensors for example, be based on Lever principle, two pressure sensors experience downward pressure, if the direction of downward pressure is positive, then two pressure pass The pressure of sensor output is normal pressure, and the sum of two normal pressures are equal to the gravity of article；When article side is in two pressure sensings When on the extended line of device line, it is based on lever principle, experiences downward pressure close to the pressure sensor of article, and far from object The pressure sensor of product experiences upward pulling force, i.e. pressure direction is negative, but two pressure sensors output pressure it Still it is equal to the gravity of article.Based on lever principle it is recognised that the pressure size and pressure experienced on pressure sensor Force snesor is related at a distance from article, therefore the pressure size that can be experienced according to pressure sensor determines article and pressure The distance between sensor, and then the location information of available article.

The case where article is placed on two pressure sensor lines and extended line is only illustrated above, and for article Not the two pressure sensor lines and extended line the case where, it can be based on lever principle and projection theory, can determine object Product are at a distance from the projection on two pressure sensor lines or extended line is between two pressure sensors.That is, Setting, can (can based on this according to the pressure change data that pressure sensor detects there are two in the case where pressure sensor To obtain weight change data) determine article one-dimensional space data, i.e. article is projected on two pressure sensor lines Position data.And the case where for being provided with more than two pressure sensors, article two dimension can be determined according to lever principle Spatial data, the determination method of every one-dimensional space data is with the mode of above-mentioned two pressure sensor, and details are not described herein.

Similarly, the case where being removed for article can also determine article position based on lever principle, no longer superfluous herein It states.

In an optional implementation of the present embodiment, as shown in Fig. 2, the step S102, i.e., according to the weight Delta data determines on the supporter the step of article condition changed article position, further comprises the steps S201-S202:

In step s 201, determine the article position in default position based on lever principle and the weight change data Set the projected position on line；

In step S202, the article position is determined according to the projected position and the predeterminated position.

In the optional implementation, lever principle is based on it is found that same article is caused by the different predetermined positions Pressure is different, and in the case where having for example multiple predetermined positions of multiple supporting points to have support respectively, different predetermined positions The pressure direction of generation may be also different.After the weight change data that multiple predetermined positions have been determined, it is based on lever principle It can determine that subpoint of the article on any two predeterminated position line arrives the distance of two predetermined positions respectively, and by It is known in predeterminated position, therefore the projected position of the subpoint is also it was determined that the projected position of the subpoint can be It, can also be on the extended line of two predeterminated position lines between two predeterminated positions；On any two predeterminated position line Projected position known in situation, can be obtained according to the position coordinates of any two predeterminated position in space coordinates To position coordinates of the article in space coordinates.If only there are two predeterminated positions, the article one-dimensional space can be determined Coordinate, and if it is more than two predeterminated positions, then it can find out 2-d spatial coordinate.For example, being provided with three on supporter A predeterminated position, respectively A1, A2 and A3；Article is removed or is placed at the position B of supporter, determined A1, After weight change data at A2 and A3, B can be determined in line A1A2, line A1A3 and line A2A3 based on lever principle On subpoint C1, C2 and C3, since the position coordinates of A1, A2 and A3 are it is known that thus may determine that subpoint C1, C2 and C3 Projected position on any two predeterminated position line A1A2, A1A3 and A2A3 of position coordinates namely article position；Later The position coordinates of article position are determined based on geometrical principle again.

In an optional implementation of the present embodiment, the predeterminated position includes be arranged on the supporter One position and the second position；The step S201, i.e., determine the article based on lever principle and the weight change data Position is further included steps of the projected position on predeterminated position line the step of
