　　The vending machine is a new mode of liquor sales. The main front-line wineries put six different brands of original cellar wines into the corresponding wine containers in vending machines and store them in restaurants and hotels. Consumers don't have to buy a whole bottle of liquor when eating in restaurants. According to their favorite liquor brands, if you use a card in the vending machine area, you can keep the quotation of liquor, each time the amount of liquor can be selected independently, at least 50 ml can be selected. This kind of fresh selling method has been accepted by many customers, and has got rid of the traditional way of selling wine.

　　由于智能自動售酒機(jī)只銷售一線原窖釀造的酒，因此自動售酒系統(tǒng)能否實(shí)現(xiàn)消費(fèi)者每次按需準(zhǔn)確取酒的愿望，已成為智能自動售酒機(jī)的關(guān)鍵技術(shù)之一。目前，自動售酒機(jī)計量系統(tǒng)的原理如圖1所示。一種自動售酒機(jī)計量系統(tǒng)，具備:通過管路2連接有隔膜泵3液位計1、通過管路2連接有隔膜泵裝置4的管路2、通過管路連接有電磁閥5的容器內(nèi)的酒通過通常的分隔件連接的隔膜泵裝置4、電磁閥5 .5、容器內(nèi)的酒用通常的隔膜泵循環(huán)進(jìn)入渦輪流量計，流量計的傳感器線圈產(chǎn)生脈沖信號變換為模擬電流量，進(jìn)而指示瞬時流量值實(shí)現(xiàn)計測的功能。

　　As the intelligent vending machine only sells the wine brewed in the original cellar of the national first-line brand, whether the automatic vending system can realize the desire of consumers to take the wine accurately on demand has become one of the key technologies of the intelligent vending machine. At present, the principle of the metering system of the vending machine is shown in Figure 1. The metering system of an automatic liquor vending machine includes: connecting the diaphragm pump 3 level meter 1 through the pipeline 2, connecting the pipeline 2 with the diaphragm pump device 4 through the pipeline 2, connecting the liquor in the container with the solenoid valve 5 through the pipeline through the diaphragm pump device 4 connected by the usual separator, the solenoid valve 5.5, the common diaphragm pump for liquor in the container circulates into the turbine flowmeter, and the sensor coil of the flowmeter. The generated pulse signal is converted into analog current, and then the instantaneous flow value is indicated to realize the function of measurement.

　　缺點(diǎn):在樣機(jī)調(diào)試過程中，發(fā)現(xiàn)不同流量計的脈沖信號一致性差，導(dǎo)致每臺自動售酒機(jī)需要單獨(dú)調(diào)試，調(diào)試工作量大，不適合大規(guī)模生產(chǎn)。此外，校準(zhǔn)特性不能長時間保持，流體的物理特性對流動特性有很大影響。

　　Disadvantage: In the process of prototype debugging, it is found that the consistency of pulse signals of different flowmeters is poor, which results in that each vending machine needs to be debugged independently, and the debugging workload is large, so it is not suitable for large-scale production. In addition, the calibration characteristics can not be maintained for a long time, and the physical characteristics of the fluid have a great impact on the flow characteristics.

　　另外，隔膜計量泵用柔性隔膜代替活塞，在驅(qū)動機(jī)構(gòu)的作用下實(shí)現(xiàn)往復(fù)運(yùn)動，完成吸入和排出過程。然而，隔膜容易損壞，流量重復(fù)精度稍低。

　　In addition, the diaphragm metering pump replaces the piston with flexible diaphragm, realizes reciprocating motion under the action of driving mechanism, completes the process of inhalation and discharge. However, the diaphragm is easy to be damaged and the flow repetition accuracy is slightly lower.
