GPS module and GPRS module design
GPS is an english abbreviation of global positioning system, and is a high-precision radio navigation positioning system based on an air satellite, which dynamically positions an object using a satellite constellation, a ground control part, and a signal receiver. Because the GPS can acquire the dynamic spatial information of the static and dynamic objects, the spatial information can be fed back quickly and accurately without the limitation of weather and time. The GPS mainly comprises three main components, namely a space component consisting of GPS satellites, a ground monitoring component consisting of a plurality of ground stations and a user component taking a receiver as a main body. The GPS receiver is used for capturing signals of satellites to be detected selected according to a certain satellite height cut-off angle, tracking the operation of the satellites, converting, amplifying and processing the received GPS signals, measuring the propagation time of the GPS signals from the satellites to the receiver antenna, interpreting navigation messages sent by the GPS satellites, calculating the three-dimensional position, even the three-dimensional speed and time of an observation station in real time and finally achieving the purpose of positioning by using the GPS. However, the GPS can only provide positioning information and cannot communicate, and the communication between the vehicle-mounted real-time monitoring terminal and the remote monitoring platform can be realized by means of GPRS technology.
GPRS is an english abbreviation for general packet radio service, a new mobile data communication service developed on the existing GSM system, and provides a connection between a mobile subscriber and a data network, providing a high-speed wireless IP for the mobile subscriber. GPRS adopts packet switching technology, each user can occupy multiple wireless channels simultaneously, and the same wireless channel can be shared by multiple users, thus providing a high-efficiency and low-cost wireless packet data service. The method is particularly suitable for intermittent, burst and frequent small-amount data transmission and is also suitable for occasional large-amount data transmission. The theoretical bandwidth of GPRS can reach 171.2Kb/s, the actual application bandwidth is about 10-70Kb/s, and the method can be used for applications such as INTERNET connection and data transmission. The main feature of GPRS technology is data packet transmission and reception. During the transportation process of the medical waste vehicle, the remote monitoring platform monitors the current position, speed and direction of the medical waste transportation vehicle in the network and the type of the medical waste loaded in the network in real time, provides information for relevant needs, such as vehicle safety, alarm information processing, vehicle running routes and vehicle running speed, provides navigation for the vehicle through GPS/GIS system integration, provides an electronic map for determining the vehicle direction for the monitoring platform, assists in planning transportation routes, selects the shortest or optimized route, and realizes the whole-process monitoring management of dangerous goods in transportation.
the GPS module acquires position information of the medical waste transport vehicle. The invention selects MAX2769GPS chip which is provided by Meixin corporation, and the chip has TTFF (Time To FistFix) with good stability, high accuracy and low power consumption. Due to the integrated packaging, the serial port can send out position information only by supplying power to the module when in use. The antenna RF has 50 Ω impedance matching and as short a length as possible when routing the PCB. In order to ensure the stability of the antenna, the invention selects an active connection method, and simultaneously adds a Low Noise Amplifier (LNA) circuit for improving the anti-interference performance, and the circuit is shown in fig. 3. The Antenna1 is connected with an Antenna without an LNA circuit, the Antenna 2 is connected with an Antenna with an LNA circuit, and the 2 antennas are arranged to compare the improvement degree of the LNA circuit on the Antenna performance.
The GPRS module is responsible for data transmission between the vehicle-mounted terminal and a second communication controller containing the GPS vehicle-mounted module in the medical waste treatment plant so as to ensure that monitoring personnel in the medical waste treatment plant can master the state of the medical waste transport vehicle at any time. The invention adopts a Quectel-M35 chip of a remote company, the chip is packaged by LCC, a strong TCP/IP protocol stack is embedded, four-frequency-band communication of GSM850MHz, DCS1800MHz, GSM900MHz and PCS1900MHz is realized, and the frequency bands are automatically searched or configured by AT commands. When the main serial port of the module is connected with the controller, a full-function serial port connection mode, a serial port connection mode with flow control and a three-wire serial port connection mode can be selected. Since the module typically has an operating voltage of 4V and a starting current > 2A, a low dropout regulator (LDO) of Micrel type MIC29302WU is selected as a power supply module when the select-M35 is powered, the output voltage of the power supply module is adjustable, and the peak value of the load current can reach 3A. In order to ensure the stability of output voltage, a voltage stabilizing tube with reverse breakdown voltage of 5.1V and dissipation power of more than 1W is arranged at the output port close to a VBAT pin of the module. The circuit is shown in fig. 2.
The GPRS module M35 is externally connected with a 100 ohm resistor respectively through an RXD pin and a TXD pin as a data receiving pin and a data sending pin; the SIM-DATA, SIM-CLK and SIM-RST pins are connected with the SIM-holder through a series 47 ohm resistor; an electrolytic capacitor and ceramic chip capacitor filtering are added at the input end of the MIC29302 for supplying power to the GPRS module; the output end and the adjusting end realize the adjustability of output voltage through resistance voltage division design, and the output end is connected with an electrolytic capacitor and a ceramic capacitor in parallel for filtering and is added with a 5.1V voltage stabilizing diode to ensure the stability of the output voltage.
Design of RFID module
the RFID technology is a short term radio frequency identification technology, and is an automatic identification technology which reads data in a non-contact mode and completes automatic acquisition of system basic data, so that the RFID technology becomes an effective tool for quickly and accurately acquiring original data required by computer information processing. RFID technology has been currently applied to various industries and fields. The composition of the RFID system varies according to different application purposes and application environments, but the RFID system mainly includes an electronic tag and a reader or a reader/writer, and further includes an antenna, an application system, and the like. Electronic tags, also called radio frequency cards, transponders, are carriers of data in which electronic data in a specific format can be stored. The reader is also called a scanner, a reading head, a communicator, a reader writer, and a reader writer according to whether the electronic tag can wirelessly rewrite data. The electronic tag and the reader realize the spatial coupling of radio frequency signals through the coupling element, and the energy transfer and the data exchange are realized in the coupling channel.
In a medical waste monitoring system, the present invention may simultaneously use a variety of RFID tags, such as medical waste tags, transportation vehicle tags, and medical waste container tags, to facilitate the collection and monitoring of medical waste information. The medical waste is provided with the RFID label, so that the supervision of the whole process from production to consumption of the medical waste can be realized. Medical waste is given unique product identification information by the production entity since it was produced, becomes a permanent label for the medical waste, and is recorded in the information system of the entity. When medical waste enters a treatment plant, information in the medical waste tag is read into the inventory management system by a reader installed at the entry of the treatment plant. When medical waste accidents occur, necessary rescue measures are taken, paper medical waste labels are easily damaged or cannot be identified due to the fact that the medical waste labels cannot be approached on the site, and therefore the treatment work of the medical waste accidents is affected. The RFID tag has the advantages of water resistance, magnetism prevention, high temperature resistance, long reading distance and the like, and once a medical waste accident occurs, the RFID tag can be remotely identified by using equipment, so that precious time is gained for correctly handling the accident. The vehicle for shipping the medical waste must comply with special regulations, unlike ordinary transport vehicles, and the supervision of the medical waste transport vehicle can be achieved using RFID technology. When the medical waste goods are shipped, the name, the quantity and the weight of the shipped medical waste goods are written into the electronic tag attached to the transport vehicle through the reader-writer arranged at the exit of the medical waste production station, the tag also comprises information such as the vehicle type, the vehicle number, the name of a driver, the name of an affiliated unit and the like, and the medical waste goods are effectively supervised based on the principle of finding goods in a vehicle. Further, the use of shipping containers for medical waste can reduce to some extent the requirements for packaging of medical waste cargo and the environmental hazards, so containers are the primary carrier of medical waste transport. Due to the closeness of the medical waste container, it is impractical to obtain status information inside the container outside the container in a wired manner, and wireless transmission of information inside and outside the container can be achieved by using the RFID technology. The medical waste logistics state information acquisition terminal writes acquired state information of various dangerous goods into an electronic tag arranged on the outer side of the container through an RFID communication module, and the RFID communication module of the vehicle-mounted real-time monitoring terminal reads medical waste information in the tag.
The RFID module of the invention adopts an MCF522 chip as a core, and the chip has abundant peripheral modules and storage space, supports a background debugging mode and is debugged based on a JTAG board level. MF RC522 has 13.56MHz read-write frequency and performs data operation through signal modulation. The MFRC522 supports the ISO 14443A standard, and data are sent to an antenna through a chip in a card, so that communication can be completed without building other circuits. The MFRC522 supports MIFARE Classic devices while supporting bi-directional data transfer. Fig. 4 is a wiring diagram of an RFID module.
