How does rfid label achieve vehicle management?

      Vehicle management is a difficult problem in city management. Traffic congestion requires intelligent traffic management technology to control it, so it can create a good and orderly traffic environment.

       Parking is a problem in big cities. It takes a lot of time to enter the parking lot, such as swiping a card. Using the Internet of Things technology, you can implement a smart vehicle management system for the parking lot. Using the smart parking lot with the rrfid label, you can install RFID on the vehicle electronic label. Temporary foreign vehicles can issue long-range RFID cards to enable vehicles to enter and exit without stopping, and can also help smart parking management and smart vehicle anti-theft goals.

        Adopt RFID label non-stop toll collection system. Now ETC tolls can often be seen on highways. This is the use of RFID technology. Bank cards installed on vehicles are equipped with electronic tags, which can be read by toll stations during operations. The writer reads and writes through the antenna, so that the Internet can be used to settle the amount with the bank, thereby achieving the purpose of charging without stopping.

        RFID tag based on RFID technology provides convenience for vehicle management, intelligent management to achieve efficient management, improve work efficiency, and improve vehicle management efficiency.

What Are The Characteristics Of A Business Process Outsourcing Project?

      The main characteristics of Business Process Outsourcing are as follows, because outsourcing is biased towards back-office business, and the times are developing rapidly. Now traditional industries and traditional business methods have fallen. To survive, traditional enterprises must change. Many companies will outsource their business in order to grasp the terminal market and quasi-market pulse.

        Outsourcing is generally biased towards mechanical business. With the current rise in prices and high manual wages, corporate profits have become less and less. Once the business volume of the company increases and the number of employees remains unchanged, adding new employees means increasing costs. So at this time, it is necessary to outsource mechanical and repetitive business through business work.

The outsourcing business is generally biased to off-site business. The important business of an enterprise is generally a job that needs to be done on-site. This needs to be completed by the enterprise itself. For off-site or network-based businesses, Business Process Outsourcing can be implemented. Enterprises can implement information technology through the Internet and partners to exchange and share information with each other.

Use and optimization of Gravure proofing machine

  Gravure proofing machine is widely used and has become an important tool for liquid ink manufacturers and users.

          The importance of Gravure proofing machine. In the process of gravure production, the guiding ideology of gravure production must be clear. To achieve the standard, the quality of the engraving cylinder should be reflected as much as possible to achieve the expected printing effect.

          What needs to be done to achieve high-quality gravure printing? First of all, we need to provide the customer with the final confirmation of the quality of the gravure plate; then we need to provide the analog basis for the digital proofing, so that the color of the digital proof can be similar to the color of the gravure; Color data information, so that the previous process can be based on evidence;

          Now the quality of the company's gravure proofing is unstable. The main reason is that these points are not done well. A set of engraving cylinders is used for proofing one at a time. Use different ink dilution ratios to trace the color of digital proofs signed by customers. This will mislead printing and make scanning and adjustment personnel unable to adjust. Therefore, the standardization and standardization of gravure proofing and data management are used to ensure proofing quality standards and Stability is very important.

Difference Between IC Card And RFID Credit Card

The IC card refers to an integrated circuit card, and a general bus card is a kind of IC card. Generally, a common IC card uses radio frequency technology to communicate with an IC card reader. The IC card stores information by the integrated circuit in the card, and the magnetic card records information by the magnetic force in the card.

The working principle is that the RF reader sends a set of electromagnetic waves of fixed frequency to the IC card. There is an LC series resonance circuit in the card, which has the same frequency as the frequency emitted by the reader. In this way, the LC resonance circuit generates resonance under the excitation of electromagnetic waves , So that there is a charge in the capacitor.

At the other end of this capacitor, a unidirectional electronic pump is connected to send the charge in the capacitor to another capacitor for storage. When the accumulated charge reaches 2V, this capacitor can be used as a power supply to provide working voltage for other circuits. Transmit the data in the card or accept the data from the reader.

RFID technology is a communication technology that can identify specific targets and read and write related data through radio signals, without the need to establish mechanical or optical contact between the identification system and the specific targets.

The basic working principle of RFID technology is that after the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip.Or the tag actively sends a signal of a certain frequency, and the reader reads the information and decodes it, and then sends it to the central information system for data processing.

A complete RFID system is composed of a reader, an electronic tag and an application software system. The Reader transmits radio frequency energy of a specific frequency to the Transponder, which is used to drive the Transponder circuit to send out the internal data. At this time, the Reader sequentially receives the decoded data and sends it to the application for corresponding processing.

In terms of the communication and energy induction methods between RFID card readers and RFID credit card, it can be roughly divided into two types: inductive coupling and backscatter coupling. Generally, the low-frequency RFID mostly adopts the first type, and the higher frequency mostly adopts the second type.

Depending on the structure and technology used, the reader can be a reading or reading / writing device, and it is an RFID system information control and processing center. The reader usually consists of a coupling module, a transceiver module, a control module and an interface unit.

The reader and transponder generally use half-duplex communication to exchange information. At the same time, the reader provides energy and timing to the passive transponder through coupling. In practical applications, management functions such as collection, processing, and remote transmission of object identification information can be further realized through Ethernet or WLAN.

The transponder is the information carrier of the RFID system. At present, most of the transponders are passive units composed of coupling elements and microchips.

What Types Of Medical Stretcher Are There?

  Medical stretcher has lifting stretcher and wheel stretcher. Shovel stretcher is generally composed of left and right aluminum alloy plates. When transporting the wounded, it is necessary to place the wounded in a supine position, and then fix the neck. After that, the left and right pieces of the stretcher can be inserted into the back from the side of the wounded and fastened before being transported.

         Negative pressure inflatable cushion type stretcher. This stretcher is generally the best tool for transporting injured patients with multiple fractures and spinal injuries. Because the inflatable cushion can properly fix the whole body of the injured person, it is necessary to inflate the cushion when in use. Then put the wounded in the pad, and then extract the air from the bag, the air cushion can harden, and the wounded is firmly fixed in it, so that it can always be stable during the transportation.

         Basket stretchers, also known as boat stretchers, are the two more common types on the market, generally aluminum alloy and synthetic resin types. It has the same shape and name as a boat. When carrying the trapped person, the trapped person is placed inside the stretcher, and the protruding edge of the stretcher cooperates with the front flat belt to seal the trapped person inside the stretcher.
