Introduction of the RFID technologyRFID is a sort of non-contact automatic identification technology, and it canautomatically identify the objective by the radio frequency signals, quickly track th
27、e goods and exchange data. Theidentification work needs not human operation, and can work under various severe environments. RFID technology canidentify high-speed objects and identify multiple tags simultaneously, and the operation is quick and simple. RFIDtechnology was generated in the Second Wor
28、ld War, and it is the successor of the traditional code technology, and itsmajor core part is the E-tag, and the identification system could read the information stored in the E-tag through theradio waves emitted by the reader-writer from a few centimeters to a few meters, and identify the identity
29、of the goods,people and objects represented by the E-tag.1.1 Composing of RFID systemRFID system is generally composed by E-tag, reader-writer and computer communication network.1.1.1 E-tagE-tag stores correlative information of the identified objects, and it is usually put on the identified objects
30、, and theinformation stored by it can be read and written by the radio frequency reader-writer through the non-contact mode.1.1.2 Reader-writerThe reader-writer is the equipment which can be used to read and write the information of the E-tag by the radiofrequency technology. The tag information rea
31、d by the reader-writer can be managed and transmitted by the computernetwork system.1.1.3 Computer communication networkIn the RFID system, the computer communication network is generally used to manage the data and complete thefunction of communication transmission. The reader-writer can connect wi
32、th the computer communication network bythe standard interface to realize the communication and data transmission.1.2 Work principle of RFID systemRFID technology is a sort of non-contact information transfer mode realized by the radio frequency signals throughspace coupling , and it identifies the
33、objective through thetransferred information. Its work principle can be described as follows : reader-writeremitsenergy in one region, form the electromagnetic field, and the size of the region is decided by the work frequency andantenna size, and when the E-tag passes this region, the system checks
34、 the signal of the reader-writer and stores theelectromagnetic wave energies emitted by the reader-writer to be the electric energy needed by the tag, and the tagtransmits the interior information to the reader-writer by the form of the radio wave, and the reader-writer accepts thedata of the E-tag,
35、 encodes and implement fault check to judge the validity of the data, and transfers the data to thecomputer communication network for the data processing.1.3 Technical characteristics of RFID1.3.1 Data read and writeRFID reader can read the data to the database without contact, and process multiple
36、tags once, and write the logisticprocessing state into the tag for the logistic processing in the next stage.1.3.2 Miniaturized and diverse formRFID will not be limited by the size or form when it reads data, so it needs not to use the paper with fixed size or printquality to fit for the precision.
37、In addition, E-tag of RFID can be applied in different products by small size, so we canmore flexibly control the production of the products, especially the application on the production line.1.3.3 Anti-pollutionRFID possesses strong anti-pollution nature for water, oil or drugs. And in the dark or
38、polluted environment, RFID alsocan read data.1.3.4 Repetitive useBecause RFID is electric data which can be written repetitively, so the tag can be used repetitively.1.3.5 PenetrabilityIf RFID is covered by the paper, wood, plastics or non-metal or non-transparent materials, it can communicate throu
39、ghthese materials except for the irons or other metals.1.3.6 Big memory capacity of dataThe data capacity will be extended with the development of the memory scale, and the quality of the material carried bythe goods is larger, the requirement of the capacity for the volume label also increase, and
40、RDID will not be restrained.1.3.7 System safetyThe system stores the data from the central computer to the work piece which will largely enhance the safety of thesystem.1.3.8 Data safetyThe checkout method or the cycle redundancy checkout method will be used to ensure the data veracity stored in the
41、radio frequency tag.2. Total design and work principle of the monitoring system2.1 System designExcept for fulfilling the function requirements, the design project should fully consider the stability,reliability,anti-jamming ability, fault-tolerance ability and abnormity protection, so the total des
42、ign of the system should beembodied in following aspects. The design could effectively identify and monitor underground personnel, and realize the humanization,informationization and automatization. The design could effectively offer personnels passing in and out, attendance and monitoring and relat
43、ivemanagement information, and once the accident happens, the design could ensure the normal implementation of therescue. The design of the system could possess the natures of safety, maintenance and expansion. The design could effectively test the concentration of harmful gases and quickly react.2.
44、2 System work principleThe underground station equipment emits the encrypted information to the exterior by the antenna and forms certainsignal emission region. The RFID cards carried by the workers will be activated when they enter into the emissionregion, and the information carried with the encry
45、pted objective identification are emitted by the emission module, andthe substation equipment will receive these signals and abstract the objective identification code, and transmit the codeto the ground computer system to complete the function of the system. When the concentration of the harmful ga
46、sesachieves certain value, the gas sensor of the substation equipment transmits the information to the A/D converter, andafter the information are converted, they are transmitted to the monitoring network to realize the test and monitoring.3. Composing and structure of the systemThe safety monitorin
47、g system includes the ground part and the underground part .The products in the system adopt the sap hanging design to ensure the normally and continually running ofthe system in the severe environment and offer power supply for 13 hours after power-down.The underground part and the ground part adopt the RS-485 serial interface standard communication and the RS-232standard serial interaction to connect with the transmission network. The data conversion interface is mainly composedby
