1. Internet of Things OverviewAccording to the now more general definition, the Internet of Things refers to the radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information-sensing equipment, according to the agreed Protocol, the use of any object connected with the Web for information exchange and communication, in order to achieve intelligent identification, positioning, tracking, A netwo

equipment through the Internet.2, communication "refers to data communication only, that is, through the computer network system and communication system to achieve the end-to-end transmission." The communication "letter" refers to the information (information), the information carrier is the binary data, the data can be used to express the traditional media form of information, such as sound, image, animation and so on. "Communication" weighs on the means of transmission or use, from this poin

How to develop the underlying hardware how to write an interface documentThese days in the supermarket RFID clearing system of the upper computer program to write, with the vb.net. The bottom is used by others to develop a good SDK, why write this article? Recently, because of the functional limitations of the device at hand, I looked for other companies on the Internet RFID card reader, because I was to do

The use of Newton's principles of physics. The method is: The standard key puts the lock pin in a straight line so that the user can turn the key.Countermeasures against key-hittingThe side pin is used to provide multiple layers of safety protection.You can also use multi-lock devices, video surveillanc

Each ZigBee network can support up to 255 devices, which means that each ZigBee device can be connected to another 254 devices.6) The effective range is small. Effective coverage range 10~75m, depending on the actual transmit power size and a variety of application patterns, can basically cover the ordinary home or office environment.7) Flexible working band

other skill sets, such as mm/Wm. however, we are seeing more of an emphasis on WM jobs lately, and that is because SAP's WM component is starting to win more projects over the best-of-breed warehouse management systems that require companies previusly opted for instead of sap wm. SAP ewm (Extended Warehouse Management) is driving some of the job orders in this module also, as companies are able to manage complex warehouses down to the storage bin level. of course, some companies have more sophi

. Currently, artificial intelligence, big data, and cloud computing are all world-class problems, I am afraid it is not something that can be done by a few Chinese undergraduate students. In terms of hardware, it requires a lot of theoretical support and often requires a huge investment to make breakthroughs. Not to mention college students. Even in China, many cutting-edge technologies, especially hardware, are lagging behind in comparison with European and American countries. We also need the

First wave: Low Frequency The development of RFID technology can be divided into three periods. The first wave is the pre-RFID era. The product types include magstripe, barcode, and 125khz sensing systems. Jen NAB is the sales director of the AEOs Professional Access Control System of NeDAP. He said that as early as 1970s, the company developed the first low-power access control card, it is based on the 70c

A few days ago open started the teensy++2.0 simulation em410x, and for the em410x of access to a brute force test, the following is the relevant code and content.What is low frequency? What is em410x?First of all, I have to mention the low-frequency cards that work at 125khz frequencies (such as em410x) so that we can better read the following content.What is low frequency? Here is the low-frequency explanation: Low frequency (LF, frequency) refers to radio waves from 30KHz to 300KHz in

This weekArticle Asynchronous Implementation of serial port operationsSome problems have been found during serial port applications such as RFID, bar code, and printing in the project: 1. Clear useless data in the serial port before using the serial port; 2. Improved methods for reading data from the serial port; 3. Data Parsing 4. Send 5. resource usage 6. logout and resource release 1. Clear useless data in the serial port before us

Card adds a lock to the warehouse and only has a key (password) can be opened for use. The CPU card is like a dedicated guard warehouse with a CPU chip in it, and the password for storing data needs to be verified. Different applications may have different passwords, so data access is more strictly controlled, the highest security. Non-contact IC cards use magnetic fields to obtain energy from the reader and exchange data. The magnetic field here is usually called the radio frequency field, s

tourism middleware research is a cutting-edge task. Currently, this work is mainly confined to the web layer, however, the development of Middleware Based on databases and wireless communication is very urgent, and there may be great breakthroughs in these periods. However, our preparations have been carried out for some time, and these time work should have some foundation. If possible, we should make progress in middleware development. the middleware development concept is based on the thesis

Work notes: hardware-related knowledge The maximum size of the standard video signal is 700mV, and the basic voltage is between 0.7-1 V. The camera output is basically a BNC connection tip: use A multimeter to test the two wires connected to the two ends. If you know the standard voltage, you 'd better test the standard voltage. Aviation plug: it is an electromechanical component that connects the electrical line. Therefore, the electrical parameters of the aviation plug must be considered first
