Description
Technical field
The invention belongs to self-service field more particularly to a kind of nobody more cargo path detection sides based on multi-frequency ultrasonic wave
Method.
Background technique
As the level of urbanization in China is continuously improved, common convenience store cannot fully meet people and do shopping to it
The working and resting arrangement of time, although 24 hours convenience stores also appear in people's lives, the considerations of for its cost, 24 urine
The distribution of Li Dian cannot fully meet the demand of people；Self-service supermarket comes into being, and general self-service supermarket is in goods
It is tagged on object, it is unified in checkout to settle accounts, but error and identification mistake are often resulted in last statistics, or be replaced
Label takes expensive commodity away with the label of low price；Traditional shelf are only used as putting the effect of commodity, can not be to quilt
The function that the cargo taken away is counted, in order to allow begun to when customer takes cargo away statistics the taken commodity of customer number
Amount, it is therefore desirable to find and a kind of be able to solve this method asked.
Summary of the invention
In view of this, needing to overcome at least one of drawbacks described above in the prior art, the present invention provides a kind of bases
In nobody more cargo path detection methods of multi-frequency ultrasonic wave, nobody more cargo paths can be applied to effective solution relevant issues,
Including the first counter module, the second counter module, for goods module, which comprises the following steps: step 1, identity
It after identification module identification, activates and is switched for the activation in goods module, each cargo path carries out initial work；In step 2, each cargo path
The ultrasonic measurement of the second counter module transmitting reception different frequency is with follower distance L0 as initial range L；
After step 3, access section picking, it is removed first counter module at cargo and counts, it is described for following in goods module
Device pushes forward commission commodity to move ahead under the driving of driving assembly, fills access section；Described second after step 4, commodity are mobile
It is the mobile distance of the follower that counter module measurement, which subtracts initial range L with the follower distance L1, L1, mobile
Distance is obtained divided by the width of one in cargo path commission commodity by the number of picking object, at this time the value of L1 be assigned to it is original away from
From L；When multiple cargo paths are removed cargo simultaneously, the ultrasonic wave that the second counter module transmitting receives different frequency is carried out
Measurement；Step 5 still has commodity taking-up before not new identity carries out identification by the identification module, repeats
Step 4；Step 6 detects identity logs other machines or enter system of paying a bill that identification module is identified, and first counts
The counting that device module and the second counter module obtain is transferred to data statistics module, and data statistics module takes in two numerical value most
Big value is as by the number of commodity.
According to described in the prior art, traditional shelf are only used as putting the effect of commodity in this patent background technique, do not have
There is the function that can be counted to the cargo being removed；And it is disclosed by the invention it is a kind of based on multi-frequency ultrasonic wave nobody is more
Cargo path detection method carries out counting statistics twice by the amount taken away to the cargo in cargo path, to determine the amount for being removed cargo,
Flip-flop number is carried out by trigger switch for the first time, the second counter with the ultrasonic wave distance mobile to cargo path by surveying
Amount, calculates the car loading being removed, so that it is guaranteed that accurate recording gets off the quantity taken away when cargo is removed, is finally aggregated into
Settlement system is accurately settled accounts.
In addition, disclosed a kind of nobody more cargo path detection methods based on multi-frequency ultrasonic wave according to the present invention, also have
