Description

一种高效全球时空编码读写系统及读写方法Efficient global space-time coding read-write system and read-write method 技术领域Technical field
本发明涉及全球卫星导航技术领域,特别涉及一种高效全球时空编码读写系统及读写方法。The invention relates to the technical field of global satellite navigation, in particular to an efficient global space-time coding read-write system and read-write method.
背景技术Background technique
当今社会,随着科学技术的发展,食品、药品安全问题也逐渐出现新的问题,食品安全和药品安全的形式也日益严峻。层出不穷的假货、有毒奶粉、假育苗等等不良食品、药品不断的危害着人们日常生活、危害青少年的身心健康。网上流传着这样的的话:中国在食品中完成了科普,从大米中我们认识了石蜡;从火腿肠中我们认识了敌敌畏;从咸鸭蛋、辣椒酱中我们认识了苏丹红;从火锅里我们认识了福尔马林;从木耳中我们认识了硫酸铜;从奶粉中知道了三聚氰胺的化学作用。而前段时间又爆发的毒、假育苗事件又让人们对药品的安全问题产生了严重的怀疑。当出现有危害的食品和药品的时候,迅速实现问题食品、药品的召回、将损害与损失降至最低、保护消费者不受有危害的食品和药品的毒害、或者在消费者食用食品和使用药品的之前能够有渠道来确认食品和药品是否为正品或来源上是否安全等等问题,也日益变得严峻和亟待解决。一个高效的、信息精确的、准确的溯源系统也就显得十分重要。而如何保证食品药品在溯源系统中的信息准确、唯一同时信息方便使用、使用效率高也就成了最主要需要解决的问题。In today's society, with the development of science and technology, new problems in food and drug safety have gradually emerged, and the forms of food safety and drug safety have become increasingly severe. The endless stream of fakes, toxic milk powder, fake seedlings and other unhealthy foods and medicines constantly endanger people's daily lives and the physical and mental health of young people. There is a saying on the Internet: China has completed science in food, we have known paraffin from rice; we have met dichlorvos from ham sausage; we have known Sudan red from salted duck eggs and chili sauce; we have known from hot pot Formalin; from fungus we know copper sulfate; from milk powder we know the chemical action of melamine. The outbreak of drugs and false seedlings that occurred some time ago has caused serious doubts about the safety of medicines. When hazardous foods and medicines appear, quickly realize the recall of problem foods and medicines, minimize damage and loss, protect consumers from poisoning by hazardous foods and medicines, or consume food and use The issue of medicines before they can have channels to confirm whether foods and medicines are genuine or safe from the source, etc. has become increasingly serious and urgently needs to be resolved. An efficient, accurate and accurate traceability system is also very important. How to ensure that the information of food and medicine in the traceability system is accurate, the only information at the same time is convenient to use, and the use efficiency is high has become the most important problem to be solved.
全球时空编码的提出就从技术上解决了信息不准确,不唯一的问题。所谓全球时空编码,是利用全球卫星导航定位技术,根据地理坐标与时间生成的一个永远不会重复的编码,采用地球球体网格编码技术,根据数据坐标形成时空数字标签,并与各种信息关联,是一个具有唯一地理位置和时间信息的编码,可以以一串数字、字符和二维码的形式体现。在货物的起点(物流起点、原产地等任意一个拟追溯的源头位置)根据卫星定位的坐标和时间,生成一个编码(字符串和二维码),该编码可以以二维码的形式固定在货物上,从而成为货物的唯一标识。在货物运输过程中,任何一个环节对其扫码均可获得货物的属性信息,同时,扫码的位置和时间将上传至云数据中心。全球时空编码能够高精度的获取当前位置坐标信息和时间信息,保证了信息的唯一性和准确性,从生产厂家到消费者都能够了解到详细的商品的准确的位置信息。虽然全球时空编 码有着高精度、信息唯一性、安全性等优点,但是也同样存在着使用上的问题:The proposal of global space-time coding technically solved the problem of inaccurate and not unique information. The so-called global space-time coding is to use global satellite navigation and positioning technology to generate a code that is never repeated based on geographic coordinates and time. It uses earth sphere grid coding technology to form a space-time digital label according to data coordinates and is associated with various information. , Is an encoding with unique geographic location and time information, which can be embodied in the form of a series of numbers, characters and two-dimensional codes. At the starting point of the goods (any point of origin to be traced, such as the starting point of logistics, origin, etc.), a code (character string and two-dimensional code) is generated according to the coordinates and time of satellite positioning. This code can be fixed in the form of a two-dimensional code On the goods, thus becoming the unique identification of the goods. In the process of cargo transportation, scan the code at any link to obtain the attribute information of the cargo. At the same time, the location and time of the scan code will be uploaded to the cloud data center. The global space-time coding can obtain the current position coordinate information and time information with high precision, ensuring the uniqueness and accuracy of the information, from the manufacturer to the consumer can understand the accurate position information of the detailed goods. Although global space-time coding has the advantages of high precision, uniqueness of information, and security, it also has problems in use:
获取的时空坐标位置无法直接使用,需要经过解码、编码等处理,并且是独立的数据,无法直接使用。经过编码加密服务器的加密算法可以将唯一的时间、空间位置坐标位置信息形成对应不变的唯一标识码,从而保证了在使用的过程中的时间、位置坐标信息的安全性和不可篡改,同时也一定程度上提高了高精度的时间、位置坐标信息的实用性。让复杂的时间、位置坐标信息变得更加可用。但是,全球时空编码到此仍然只是一个“简单的”编码,无法使用在实际物流等环境,需要和相关的物流信息载体或者平台结合,才能将全球时空编码的优势体现出来。The obtained spatio-temporal coordinate position cannot be used directly, it needs to be decoded and encoded, and it is independent data and cannot be used directly. The encryption algorithm of the encoded encryption server can form the unique time and space position coordinate position information into a corresponding unique identification code, thereby ensuring the safety and non-tampering of the time and position coordinate information in the process of use. To a certain extent, the practicality of high-precision time and position coordinate information is improved. Make complex time and position coordinate information more usable. However, the global spatio-temporal coding is still only a "simple" code. It cannot be used in actual logistics and other environments. It needs to be combined with related logistics information carriers or platforms to realize the advantages of global spatio-temporal coding.
随着射频识别(RFID)电子标签的出现取代了传统的纸质二维码标签,在大批货物以及多个小件在一个大的包裹或者集装箱中,需要快速获得所有货物信息,并将货物统计录入仓储信息系统中、同时也需要实现快速查找货物、提调货物,这些实际操作的问题相较于使用传统二维码的操作,射频识别(RFID)有着更大的优势和实用性。With the advent of radio frequency identification (RFID) electronic tags replacing traditional paper two-dimensional code tags, in the case of large quantities of goods and multiple small pieces in a large package or container, it is necessary to quickly obtain all cargo information and collect the cargo statistics Entering into the warehousing information system, and at the same time, it is also necessary to quickly find the goods and raise the goods. These practical operational problems have greater advantages and practicality than radio frequency identification (RFID) compared to operations using traditional two-dimensional codes.
