codes, RFID, and so on can be used. (5) system integration is very difficult. The MES system is closely related to the basic data, production plan, cost management, quality management, equipment management, and performance management of ERP. The difficulty of integration can be imagined. The integration of MES and the underlying control system also makes it very difficult to integrate interfaces because of the wide variety of devices.

The date and time type is the data type used to indicate "year-month-day hour: minute: Second", and its precision is accurate to "second ", it contains the year, month, day, hour, minute, and second information, for example, "08:00:00 ". The date type can be used to indicate the "Beijing Olympic Games opening ceremony accurate time", "Last late time" and other information. In databases, datetime is generally used to represent the datetime type. The precision of the date and time type is accu

Complex Event Processing introduces the open-source Esper. nesper is an event stream processing (ESP) and complex event processing (CEP) system, which can monitor the event stream and trigger certain actions when a specific event occurs-it can be seen that the database is in turn, the statements are fixed, and the data stream is in and out. Event processing is a development trend in the software industry. It has been added to this market by several large manufacturers and many startups. Examples

With the development of the application of electronic information technology, many occasions need to identify the specific user groups or identity records, such as access control system, attendance system, security certification system, in a variety of systems used in various forms of technology, such as retinal recognition, face recognition, fingerprint identification, RFID applications such as radio frequency identification. Among them, the biometri

IBeaconIBEACON[1] is a new feature on the OS (iOS7) for mobile devices released by Apple in September 2013. The way it works is that devices with low-power Bluetooth (BLE) communication capabilities use BLE technology to send their own unique IDs around, and the application that receives that ID takes some action based on that ID. For example, if you set up a ibeacon communication module in

At the beginning, I wanted to achieve a map effect in my resume: get the current position of HR automatically, and make distance difference with my location. If within the corresponding range, the corresponding dialog box pops up Balabala.

There is a need to write code today: In order to be unified with other devices in the same product, the host computer requires processing strings, not arrays. We all know that the array is convenient when processing the data, but considering the other devices (yes, I said that TI430 do RFID card reader device, and the protocol between the host computer is the string/laughter), tried to change the 16 binary data into a string, that is, 0xAB, changed to

Recently, the school's laboratory took a small project-time card system, the use of RFID in the hardware layer to obtain the student card ID, through the WiFi transmission to the server, the attendance information storage, the mobile phone side to obtain the server data. I am responsible for the software part and another hardware child paper together to achieve this small project, but the baby did not wri

Big data has become almost the latest trend common in all business sectors, but what is big data? is a gimmick, a bubble, or really as important as rumors. In fact, big data is a very simple term-as it says, it is a very large data set. So what is the majority? The real answer is "as big as you think"! So why do you have such a large data set? Because today's data are ubiquitous and hugely rewarding: the RFID sensors that collect communications data,

Crab society, the only purpose of each citizen is to have fun, but the price is that everyone 1-30 years old, will be killed in a grand ceremony. To avoid panic and rebellion, everyone was told that everyone would be reborn immediately. All babies are implanted with a chip in their palm at birth to track and monitor age. The chip prototypes in the movie are similar to the RFID chips that now provide great convenience for life. In the Gattaca, the pro
