Description
Technical Field
The present invention relates to a signal transmitting and receiving device, and more particularly, to a reader.
Background
Because many chronic patients (such as schizophrenia) have great defects in behavior normalization and behavior pattern development capability, the feasibility of the pure artificial training is often poor. In order to ensure that patients can take medicines in a quantitative manner on time according to medical orders, some medicine administration supervision products are generated.
The intelligent medicine box is a precursor product in the intelligent medical field. Smart kits also have a significant limitation. For example, intelligent kits can only determine whether a medication is removed from the kit and cannot determine whether a patient has taken the medication. For schizophrenic patients, their non-compliance with drugs results to some extent from the contradiction of drugs by their side effects or from the fear of the addition of hazards from relatives and medical staff. When they are required to take the medicine, they may have the medicine hidden in the body and not taken. For this situation, it is difficult for the intelligent kit to determine whether the patient is taking the medicine, thereby delaying the treatment process and exacerbating the patient's condition.
In this context, the emerging concept of "smart tablets" emerges. Smart tablets can monitor where the drug is located by the differences that the tablet exhibits under different circumstances. Smart tablets produced by the us protein company, which is currently the mainstream, trigger the built-in chip with gastric acid, so as to transmit signals. The appearance of the intelligent tablet greatly improves the defects of high misjudgment rate and poor supervision of the intelligent medicine box, provides convenience for doctors to supervise the medicine taking condition of patients in real time, and realizes 'accurate medical treatment'.
However, by analyzing the solutions currently available, almost all smart tablets require a built-in power supply for power and are costly. Because the market of the intelligent tablet is positioned for patients afflicted with chronic diseases to take every day, the cost rise caused by the complex structure is likely to be unfavorable for the popularization of the intelligent tablet among the patients, and the principle of general medical treatment is violated. In addition, intervention of a power supply can bring a certain influence to the reliability and the service life of the intelligent tablet, and is not beneficial to stable monitoring of the compliance of the patient. If the smart tablet adopts a wireless passive mode, a reader with good receiving and transmitting performance is needed. At present, most readers have the problems of poor performance of a receiving loop, low speed of receiving or generating frequency signals and the like, meanwhile, the work of the readers is also influenced by the distance, and the readers cannot receive signals too far.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The invention is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
As shown in fig. 1 and 2, the present invention provides a reader. The reader is connected with an intelligent capsule through a spiral antenna, and the spiral antenna 20 is arranged in the intelligent capsule;
The intelligent capsule comprises a capsule shell 16, an acid-soluble cover 18 for closing an opening on a side wall of the capsule shell 16 is arranged on the side wall of the capsule shell 16, a piston 19 is arranged in the capsule shell 16, and the piston 19 and the acid-soluble cover 18 enclose a closed space for storing powdery or liquid medicines;
one side of the piston 19 facing away from the closed space is connected with one end of the spiral antenna 20, the other end of the spiral antenna 20 is connected with a printed circuit board 22, and one side of the printed circuit board 22 facing away from the spiral antenna 20 is connected with a sensor 21 fixed on the inner side wall of the capsule shell:
When the medicine is completely released from the closed space through the opening of the acid-soluble cover 18 after dissolution, the spiral antenna 20 is restored to the original length and works at the normal working frequency of the spiral antenna 20, and the sensor 21 sends a sensor message to the reader through the spiral antenna 20;
The spiral antenna 20 of the smart capsule is assumed to be a civilian communication frequency 433MHz and its sensor 20 is a single resonator SAW sensor.
The reader includes:
The communication antenna module is used for receiving and transmitting signals and comprises a flat antenna 2 and a duplexer 1, so that the switching function of receiving and transmitting signals is realized; considering that the sensor selected by the design is a passive system, the gain of the antenna of the reader should be improved in order to obtain a longer signal receiving distance. The patch antenna 2 employs a high-gain patch antenna having a communication frequency of 433 MHz.
The signal acquisition and processing module 15 is used for signal digital processing and can generate a target digital signal.
A radio frequency transceiver module 14 comprising:
the frequency synthesizing unit 10 is connected to the communication antenna module on one side and to a quadrature demodulating unit 9 on the other side. The time domain pulse query method requires that the frequency of the excitation pulse is close to the resonance frequency of the resonator (433 MHz in the present design), and meanwhile, the frequency accuracy of the local oscillator signal input of the mixer 12, the quadrature demodulation 9 and other units will significantly affect the performance of the receiving loop. In order to ensure the frequency accuracy, the signal-to-noise ratio and the response speed of local oscillation signals and excitation pulses, the design selects a frequency synthesizer SI4133G produced by the American Silicon Lab company as a frequency synthesizer.
And the orthogonal demodulation unit 9 is also connected with the signal acquisition and processing module 15, and the orthogonal demodulation unit 9 performs down-conversion on the logarithmically amplified echo signals to obtain two paths of orthogonal signals with better dynamic performance. In order to mitigate the effect of this phenomenon on the resonant frequency resolution, the echo signals of SAW resonators in the smart capsule have an initial phase, and the log-amplified echo signals need to be down-converted by using the quadrature demodulation unit 9. The design selects LT5506 chip produced by Linear Technology company to demodulate and low-pass filter the signal.
The direct digital synthesis unit 5 is connected with the signal acquisition and processing module 15 on one side and the communication antenna module on the other side. In order to ensure stronger adaptability and universality of the reader transmitting unit, a frequency synthesizer with adjustable frequency needs to be designed and generated. Considering that the traditional frequency synthesis technology can not meet the requirement of quickly generating a target frequency signal, the design selects a high-speed direct frequency synthesis chip AD9958 produced by AD company in America to form a frequency generation unit with adjustable frequency together with a frequency synthesizer. The frequency synthesis unit 10 in the radio frequency transceiver module 14 is connected in parallel with the direct digital synthesis unit 5, so that the signal transmission and reception do not affect each other.
The logarithmic limiting amplifying unit 11 is configured to amplify the echo signal, and the logarithmic limiting amplifying unit 11 is connected between the communication antenna module and the quadrature demodulating unit 9. The SAW resonator in the smart capsule will generate an echo and return to the reader after receiving the signal from the radio frequency transmitting unit, but since the SAW resonator is a passive device, the echo signal is in a free decay phase after being generated. In order to keep all echo signals as far as possible in consideration of the near logarithmic relation between the attenuation of the echo signals and time, a logarithmic amplifier is adopted to carry out limiting amplification on the echo signals. The design adopts a multistage logarithmic limiting amplifier AD8309 manufactured by Analog Device Inc. to amplify echo signals.
A mixer 12 and a low noise amplifier (Low Noise Amplifier, LNA) 13 are also arranged between the logarithmic limiting amplification unit 11 and the communication antenna module. The mixer 12 is connected to a low noise amplifier 13. The mixer 12 may mix the specific frequency signal generated by the frequency synthesizing unit 10 with the received frequency signal to obtain an intermediate frequency signal. Preferably, the frequency of the specific frequency signal generated by the frequency synthesizing unit is 842MHz. The low noise amplifier 13 is used to amplify the signal received from the antenna for processing by the electronics of the subsequent stage.
The radio frequency transceiver module 14 is further provided with a power amplifier 3, and the power amplifier 3 is connected between the direct digital synthesis unit 5 and the communication antenna module. The power amplifier 3 is used for amplifying the target frequency signal, and the signal is transmitted after being processed, so that the intelligent capsule can be received.
The power amplifier 3 and the direct digital synthesis unit 5 are provided with a high-speed switch 4 therebetween. The high-speed switch 4 is also called a fault current limiter, a fast switch, a high-speed current limiting protection switch, a current limiting protector. The main function is to switch the short-circuit current off at high speed before it does not rise to its peak value. This design is advantageous for line protection of the reader.
The signal acquisition and processing module 15 comprises:
The analog-to-digital converter 8, the analog-to-digital converter 8 converts the frequency signal of the quadrature demodulation unit 9 into a digital signal and transmits the digital signal to a digital signal processor 7 (DIGITAL SIGNAL Processing, DSP) for Processing.
A complex programmable logic device (Complex Programmable Logic Device, CPLD) 6, one side of which is connected to the digital signal processor 7 and the analog-to-digital converter 8, respectively, and the other side is connected to the direct digital synthesis unit 5 and the frequency synthesis unit 10, respectively. The complex programmable logic device 6 is a high density, high speed and low power consumption programmable logic device. Complex programmable logic devices, which are devices developed from programmable array logic (Programmable Array Logic, PAL) and generic array logic (GENERIC ARRAY logic, GAL) devices, are relatively large-scale, complex in structure, and belong to the field of large-scale integrated circuits. Is a digital integrated circuit with logic functions which are built by users according to the needs of the users. The basic design method is to generate corresponding target files by means of an integrated development software platform and using methods such as schematic diagrams, hardware description languages and the like, and transmit codes to a target chip through a downloading cable (programming in a system) to realize a designed digital system.
The CPLD6 is mainly composed of programmable interconnect matrix cells surrounded by programmable logic Macro Cells (MC). The MC structure is complex and has a complex orthogonal unit interconnection structure, and a specific circuit structure can be generated by a user according to the needs to complete certain functions. The method has the characteristics of flexible programming, high integration level, short design development period, wide application range, advanced development tools, low design and manufacturing cost, low requirements on hardware experience of designers, no need of testing standard products, strong confidentiality, popularization of price and the like, and can realize large-scale circuit design.
The echo signals are received and preprocessed by the transceiver module and then enter the signal processing module for processing and calculation. The design selects 5509A digital signal processing chip produced by TI company. For the sequential logic control unit, EPM1270 chip manufactured by Altera company is selected.
For the transmitting loop of the radio frequency pulse, the signal acquisition and processing module 15 and the direct digital synthesis unit 5 are utilized to generate a target frequency pulse, and the target frequency pulse is filtered and amplified to be used as an excitation signal to be transmitted to the SAW sensor through the antenna. To save space, the present design employs a planar antenna 2 and utilizes a duplexer 1 as a transmit-receive controller.
For the echo receiving loop, the signal is first amplified by LNA13 and mixed with the 842MHz signal. The intermediate frequency signal obtained after mixing is subjected to amplitude limiting amplification unit 11 and quadrature demodulation unit 9 to obtain two paths of quadrature signals with better dynamic performance, and the two paths of quadrature signals can be further processed by DSP7 after analog-to-digital conversion.
