技术领域technical field
本发明涉及一种具有食品管理系统的冰箱及相关的食品管理方法。The invention relates to a refrigerator with a food management system and a related food management method.
背景技术Background technique
随着生活节奏的不断加快以及消费者生活水平的不断提高，人们对作为生活常用品的冰箱有着越来越高的要求。目前，冰箱已发展为具有食品管理的功能，例如，可以提示用户冰箱中有何种食品、食品的存储期限等。这使得冰箱不再仅是传统意义上的带有储存功能的温度调节器，而是一个可以对食品进行分类管理、集储存与信息功能于一体的现代化管理装置。With the continuous acceleration of the pace of life and the continuous improvement of consumers' living standards, people have higher and higher requirements for refrigerators as daily necessities. At present, the refrigerator has been developed to have the function of food management, for example, it can remind the user what kind of food is in the refrigerator, the storage period of the food and so on. This makes the refrigerator no longer just a temperature regulator with storage function in the traditional sense, but a modern management device that can classify and manage food and integrate storage and information functions.
对于冰箱的食品管理功能，关键在于如何识别放入或取出的食品种类以及重量等信息。目前的食品输入方法大多数是手工录入的方法，或采用条码扫描的方法，这要求用户在把食品放入或取出冰箱时逐一扫描条形码，导致操作变得复杂、不便利。For the food management function of the refrigerator, the key lies in how to identify information such as the type and weight of the food put in or taken out. Most of the current food input methods are manual input methods or barcode scanning methods, which require users to scan the barcodes one by one when putting food into or taking it out of the refrigerator, resulting in complicated and inconvenient operations.
目前的食品输入也有采用摄像头的方法；在这种方法中，冰箱内置了一个摄像头，其采用物体识别系统，使得每当有食品放入或取出冰箱时，摄像头便会将图片发送到互联网中的图片搜索服务，例如，谷歌的图片搜索服务，即，无需用户参与便可判断用户往冰箱里放入或从冰箱里拿出了什么东西。然而，这种采用摄像头方法进行的食品输入并不可靠且不稳定，需要长达约5s才能分析特定图片并返回结果，还时常存在难以识别的情况。The current food input method also uses a camera; in this method, a camera is built into the refrigerator, which uses an object recognition system, so that whenever food is put into or taken out of the refrigerator, the camera will send the picture to the Internet. Image search services, such as Google's image search service, can determine what the user puts in or takes out of the refrigerator without user participation. However, the food input using the camera method is unreliable and unstable. It takes about 5 seconds to analyze a specific picture and return the result, and it is often difficult to identify it.
此外，目前的食品输入方法还有采用RFID无线射频识别技术进行自动识别。然而，在实际生活中，几乎没有食品会使用RFID标签，而且RFID标签也没有统一的编码标准。In addition, the current food input method also uses RFID radio frequency identification technology for automatic identification. However, in real life, almost no food will use RFID tags, and there is no uniform coding standard for RFID tags.
因此，需要一种新颖的具有便利性、可靠性和实用性的食品管理系统的冰箱。Therefore, there is a need for a novel refrigerator with convenience, reliability and practicality of a food management system.

下面参照图1-2描述本发明的用于上述冰箱的食品管理方法。该食品管理方法包括：The food management method for the refrigerator of the present invention will be described below with reference to FIGS. 1-2. This food management approach includes:
通过门开关2给出的信号激活食品管理系统30；The food management system 30 is activated by the signal given by the door switch 2;
根据放入或取出食品时重量检测传感器4来感测置物架3上的重量变化，微处理器模块10自动确定放入或取出食品的重量和不同的置物架位置，并记录放入时间或取出标识；Sensing the weight change on the shelf 3 according to the weight detection sensor 4 when putting in or taking out the food, the microprocessor module 10 automatically determines the weight of putting in or taking out the food and the different shelf positions, and records the time of putting in or taking out logo;
在置物架3上发生重量变化后，微处理器模块10通过语音模块6、音频驱动放大模块11和喇叭8与用户进行语音交互；After the weight change occurs on the rack 3, the microprocessor module 10 performs voice interaction with the user through the voice module 6, the audio drive amplification module 11 and the loudspeaker 8;
通过拾音器7语音输入放入或取出食品的名称，经由语音模块6将语音信息识别并转换为存储在食品信息存储器中的代码信息；以及The name of putting in or taking out the food is voice-inputted through the pickup 7, and the voice information is recognized and converted into code information stored in the food information memory via the voice module 6; and
根据食品信息存储器中存储的食品的名称、重量、位置及放入时间或取出标识，以及微处理器模块10与用户之间的语音交互，对食品进行自动化管理。Food is managed automatically according to the name, weight, position and time of putting in or taking out of the food stored in the food information memory, and the voice interaction between the microprocessor module 10 and the user.
优选地，在本发明的食品管理方法中，可以将所述语音信息通过一个额外的通信模块发送到远程的云平台语音识别系统进行语音识别，并将所述云平台语音识别系统返回的识别结果通过通信的方式传递到微处理器模块。Preferably, in the food management method of the present invention, the voice information can be sent to a remote cloud platform voice recognition system through an additional communication module for voice recognition, and the recognition result returned by the cloud platform voice recognition system Passed to the microprocessor module by means of communication.
本发明的具有食品管理系统的冰箱通过语音模块、音频驱动放大模块、喇叭及拾音器能够与用户进行简单的语音对话。例如，当用户打开冰箱的门，将食品放入置物架上，食品管理系统检测到门开关信号进而激活食品管理系统，同时通过设置在置物架下方的重量检测传感器检测到置物架上的重量变化，进而使食品管理系统与用户进行简单的语音对话，例如，“您刚才放入的是什么？”，用户只要回答食品的名称即可，用户的语音输入通过拾音器进入语音识别及转化模块进行识别和转换，并将识别的代码信息存储到食品信息存储器中，记录下食品的名称、重量、放入位置、放入时间（由此确定保质期，以对即将过期的食品给予语音提醒），以对食品进行自动管理。或者，为了减少错误，食品管理系统将自动识别出的食品名称询问用户，得到用户的肯定回答后，再增加进入食品信息存储器。The refrigerator with the food management system of the present invention can conduct simple voice conversations with the user through the voice module, the audio drive amplifier module, the loudspeaker and the pickup. For example, when the user opens the door of the refrigerator and puts food on the shelf, the food management system detects the door switch signal to activate the food management system, and at the same time detects the weight change on the shelf through the weight detection sensor installed under the shelf , and then enable the food management system to conduct a simple voice dialogue with the user, for example, "What did you put in just now?", the user only needs to answer the name of the food, and the user's voice input enters the voice recognition and conversion module through the pickup for recognition and conversion, and store the identified code information in the food information storage, record the name, weight, location, and time of the food (thereby determine the shelf life, and give voice reminders to foods that are about to expire), so as to Food is managed automatically. Or, in order to reduce errors, the food management system will ask the user for the name of the food that is automatically recognized, and after getting an affirmative answer from the user, add it to the food information storage.
当从冰箱中取出食品时，由于重量减轻，食品管理系统可以自动找到与之重量匹配的食品，并从食品信息存储器中将其删除，或者，为了减少错误，食品管理系统可以通过语音模块、音频驱动放大模块和喇叭与用户进行语音交互，将自动识别出的食品名称询问用户，得到用户的肯定回答后，再将该取出的食品从食品信息存储器中删除。如果取出的只是食品的一部分，也需要通过对话的形式确定食品名称，并从食品信息存储器中核减该食品的重量；另外，根据食品信息存储器中记录的信息，如果取出的食品即将过期或已经过期，食品管理系统能够给予语音提醒。When taking food out of the refrigerator, due to the weight loss, the food management system can automatically find the food with the matching weight and delete it from the food information memory, or, in order to reduce errors, the food management system can use the voice module, audio Drive the amplification module and the speaker to perform voice interaction with the user, ask the user the name of the food that is automatically recognized, and delete the food taken out from the food information storage after getting an affirmative answer from the user. If only part of the food is taken out, it is also necessary to determine the name of the food through dialogue, and subtract the weight of the food from the food information storage; in addition, according to the information recorded in the food information storage, if the food taken out is about to expire or has expired , the food management system can give voice reminders.
本发明的具有食品管理系统的冰箱具有友好的人机语音交互界面，以及简单的语音输入方式，能够自动确定食品存放的位置，并且在一定条件下能自动确定所取出的食品类型及数量。The refrigerator with the food management system of the present invention has a friendly man-machine voice interaction interface and a simple voice input method, can automatically determine the location of food storage, and can automatically determine the type and quantity of food taken out under certain conditions.
应理解，在不偏离本发明的实质精神的情况下，任何对于本发明的改进、变型或修改，都旨在被包括在本发明所附的权利要求书的保护范围之内。It should be understood that, without departing from the essential spirit of the present invention, any improvement, modification or modification of the present invention is intended to be included within the scope of protection of the appended claims of the present invention.
