Embodiment Construction

[0023] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to figure 1 , a multi-objective temperature optimization control method for an intelligent retail machine, said method comprising the steps of:

[0025] (1). According to the two decision variables of external environment temperature and equipment internal setting temperature, a multi-objective suitable temperature model is constructed under the constraint conditions, and a suitable temperature solution set is obtained;

[0026] Multi-objective optimum temperature model:

[0027]

[0028] N in the formula refers to dividing the day from 9 o'clock to 20 o'clock into N same time blocks, and different k values ​​represent the subscripts of different time blocks; Tin(k) in the formula is the time block Tmin is the lower limit of food preservation temperature, Tmax is the upper limit of food preservation temperature, En(k) is...

Abstract

A multi-objective temperature optimization control method for an intelligent retail machine, comprising the following steps: (1) constructing a multi-objective suitable temperature model under satisfying constraint conditions according to two decision variables of external environment temperature and equipment internal setting temperature, and obtaining a suitable temperature solution (2) Determine the multi-objective optimal temperature solution for commodity preservation time, equipment energy consumption, and sales; extract the optimal internal set temperature value under different ambient temperatures from the optimal temperature solution, and use the compressor closed-loop stability control . The invention controls the compatibility of the three goals of food preservation, equipment energy saving and economic benefits that need to be met in the operation process of the intelligent retail machine. While meeting the requirements of food preservation, it also reduces energy consumption, improves economic benefits, and realizes a comprehensive The ultimate goal of optimal efficiency.

Description

technical field [0001] The invention belongs to the field of unmanned retail, and in particular relates to a multi-objective temperature optimization control method of an intelligent retail machine. [0002] technical background [0003] A smart vending machine is an unsupervised self-service purchase of goods. The goods are temporarily stored in the smart vending machine provided by the supplier. The smart vending machine needs to provide a suitable environment for the goods to meet the storage requirements, especially for food. Commodities have high fresh-keeping requirements. Merchants not only need to extend the fresh-keeping time as long as possible, but also hope to save energy consumption of retail machines as much as possible and reduce operation and maintenance costs to achieve the goal of improving economic benefits. However, the existing smart retail machines It is difficult for temperature control methods to meet this multi-objective requirement. [0004] Since t...
