Abstract
The invention provides the processing method of a reader/writer of a portable wireless responder, which solves the problem in checking the to-be-read data information stored in the responder in the maintenance process of the responder. However, the responder as an outdoor apparatus is subjected to encapsulation treatment by manufacturers. The processing method comprises the following steps: radiating the responder with an electromagnetic energy of 27.095 MHz by an apparatus when carrying out reading operation, simultaneously receiving a frequency shift keying signal returned from the responder, amplifying and demodulating the signal to generate a data code, and comparing with an original data; and, during writing operation, writing the data into the responder by using the carrier energy as the work power supply of the responder according to the constant-amplitude keying principle of the carrier with 9.032 MHz, reading the data, comparing with write information, reporting the successful writing if the read is consist with the write information, and analyzing the content and the meaning of the message. The processing method aims to achieve reading or modification of the responder in a wireless reading/writing manner without changing components of the responder.
Description
Technical field
The present invention relates to processing method that canned data in the large capacity spot type answering machine is read or revises, it helps the alter operation of stored information in the regular maintenance of transponder device and the equipment.
Background technology
Transponder device is used on many high-speed railways at home as the chief component of high-speed railway row control equipment at present.In the maintenance process of transponder, need read the data message that is stored in wherein and check, with guarantee driving safety.And the change of environment, facility (for example information such as the gradient, bridge, speed limit) is carried out corresponding modification to the information in the transponder around, but because transponder is an outdoor equipment, itself has functions such as waterproof and dustproof requirement, so the manufacturer of transponder has all adopted the embedding processing to transponder.Impossible when wanting to change the components and parts in the transponder.Therefore must use the mode of radio read-write.
Summary of the invention
The object of the present invention is to provide a kind of processing method of read-write device of portable wireless answering machine.
The object of the present invention is achieved like this: when carrying out read operation, to transponder radiation 27.095MHz electromagnetic energy, receive the frequency shift keying signal that transponder returns by equipment simultaneously, amplify and demodulation, generate numeric data code,, can detect the complete of data in the transponder with the initial data comparison.During write operation, utilize the constant amplitude keying principle (otherwise when 9MHz is arranged be 1 be 0) of 9.032MHz carrier frequency, the carrier frequency energy is as the working power of transponder.Write data into transponder.With data readback, compare then with writing information.Unanimity is then reported and is write success, and message content and implication are resolved.
The present invention has filled up the blank of present China aspect the transponder read and write device.Be the great-leap-forward development of cooperation Chinese Railway, and the arterial railway Signal Products is provided in the speed-raising process, it has, and cost is low, the characteristics of easy care.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is the work block diagram of read write line.
Embodiment
Adopt notebook computer, load special-purpose software, send by software and read sign indicating number, write the sign indicating number order, and show the information that reads and keep a record.
Message is write fashionable, and message data is modulated on the 9.032MHz high-frequency signal in the mode of ASK.Amplification sends to transponder through high frequency power.Transponder receives the energy of this signal as message rewriting circuit, and demodulation ASK signal, and the reduction message data is rewritten the transponder content.
When message read, read write line sent the continuous constant amplitude power signal of high frequency of 27.095MHz.Transponder receives the power supply energy of this signal as transponder work.Read write line receives the fsk signal that transponder returns, and amplifies and demodulation, generates numeric data code, with the initial data comparison, can detect the complete of data in the transponder.
Claims (1)
1, a kind of processing method of read-write device of portable wireless answering machine is characterized in that: when carrying out read operation, by equipment to transponder radiation 27.095MHz electromagnetic energy, receive the frequency shift keying signal that transponder returns simultaneously, amplify and demodulation, generate numeric data code, compare with initial data; During write operation, utilize the constant amplitude keying principle of 9.032MHz carrier frequency, the carrier frequency energy is as the working power of transponder, write data into transponder,, compare with writing information then with data readback, unanimity is then reported and is write success, and message content and implication are resolved.
