[0021] See also Figure 1 , is a schematic diagram of the structure of a mobile device compatible with a POS machine with a built-in antenna and a telescopic antenna of the utility model. Figure 1 As shown, in the mobile device with a built-in antenna and a whip antenna compatible with a POS machine provided in the first embodiment of the utility model, at least a mainboard, a processor, a single-pole double-throw switch, a built-in antenna, a whip antenna, a whip antenna adapter board, a built-in antenna interface, a whip antenna interface, and a radio frequency IC are included. The single-pole double-throw switch and the processor are both arranged on the mainboard. The single-pole double-throw switch is used to switch the use status of the built-in antenna and the whip antenna. The whip antenna is connected to the mainboard through the whip antenna interface via the whip antenna adapter board, and the built-in antenna is connected to the mainboard through the built-in antenna interface.
[0022] In some optional implementations, both the built-in antenna interface and the telescopic antenna interface are provided with features such as waterproof and dustproof to adapt to complex and changeable mobile usage environments.
[0023] The built-in antenna can be directly welded or fixed on the mainboard, and connected to the RF circuit of the mainboard through the built-in antenna interface to ensure stable signal transmission.
[0024] The function of the telescopic antenna adapter board is to convert the signal of the telescopic antenna into a format recognizable by the mainboard, while providing necessary protection and filtering functions.
[0025] Whether it is a built-in antenna or a telescopic antenna, their main function is to receive and transmit wireless signals. When the POS machine needs to communicate with an external network, the built-in antenna or telescopic antenna will receive the signal from the base station or network and process it through the RF IC.
[0026] The design of the SPDT switch allows users to flexibly select the antenna type according to the usage scenario. For example, when the signal is weak or a wider coverage area is required, a telescopic antenna can be selected; when the location is fixed or the signal quality is good, a built-in antenna can be selected.
[0027] The signal processed by the RF IC will be further transmitted to the communication module of the POS machine, such as the 4G module, for data encoding and decoding, encryption and decryption, and finally interact with the payment system or bank through the network.
[0028] The RF IC is a key component that connects the antenna and the communication module. It is responsible for processing RF signals, including modulation, demodulation, amplification and other functions to ensure the quality of the signal.
[0029] RF IC is mainly responsible for receiving, sending and processing signals. When the POS machine needs to read the information of a bank card or mobile payment device, the RF IC receives the RF signal through the antenna and converts the signal into a digital signal for the device to process. Conversely, when information needs to be sent, the RF IC converts the digital signal into a RF signal and transmits it through the antenna.
[0030] In this process, RF IC also plays an important role in signal modulation and demodulation. Modulation is the conversion of digital signals into RF signals suitable for transmission. Common modulation methods include amplitude modulation, frequency modulation, and phase modulation. Demodulation is the restoration of the received RF signal to the original digital signal for subsequent processing by the device. This modulation and demodulation process ensures the accurate transmission of information and provides a strong guarantee for the security of mobile payments.
[0031] In addition, RF IC also has RF signal processing functions. This includes amplifying, filtering, mixing and other operations to improve the reception quality and transmission efficiency of the signal. The filtering operation can remove stray signals, retain useful signals, and ensure the clarity and accuracy of information; the mixing operation can mix the RF signal with the local oscillation signal to generate an intermediate frequency signal for subsequent signal processing.
[0032] In specific implementation, the RF IC can be but is not limited to MT6177. The RF IC MT6177 is an excellent 40nmCMOS multi-mode multi-band highly integrated transceiver. It supports multiple modes such as C2K, GGE, WCDMA, TDSCDMA, LTE and LTE-CA. This comprehensive compatibility enables MT6177 to easily cope with various complex communication environments and meet the needs of different operators and users. Whether it is traditional 2G, 3G networks or emerging 4G, 5G networks, MT6177 can provide a stable and efficient communication experience. It adopts a direct conversion transmitter and a hybrid direct conversion / low intermediate frequency receiver design, which not only improves the signal conversion efficiency, but also reduces power consumption and cost. At the same time, MT6177 also supports SAWless Rx input port, which further simplifies the circuit structure and improves the reliability of the system. It supports high-power UE (HPUE) and can meet the communication needs in various complex scenarios. At the same time, MT6177 also has a powerful RF calibration function, which can effectively eliminate image interference, LO feedthrough, IIP2, DC offset and RC angle problems to ensure signal accuracy and stability. It adopts a dual DC-DC converter design, which can effectively reduce the power supply current, achieve longer standby time and more stable operation. This low power consumption feature makes MT6177 have a wide range of application prospects in low-power application scenarios such as mobile devices and IoT devices.
[0033] During specific implementation, the telescopic antenna adapter board includes an antenna interface, a filter, and an amplifier.
[0034] Antenna interface: used to connect the telescopic antenna to ensure that the antenna can transmit signals stably and efficiently. The interface design needs to consider the antenna model, specifications and signal transmission characteristics to ensure the best matching effect.
[0035] The filter is used to filter out clutter and interference in the signal to improve the signal quality; the amplifier is used to enhance the amplitude of the signal to ensure that the signal is not easily attenuated during transmission. The combination of the two can effectively improve the transmission efficiency and stability of the signal.
[0036] In specific implementation, the telescopic antenna adapter board is also equipped with an impedance matching network. The impedance matching network can achieve impedance matching between the antenna and the mainboard, reduce signal reflection and loss, and ensure smooth signal transmission. When designing an impedance matching network, it is necessary to fully consider the impedance characteristics of the signal source, transmission line, and load, and through reasonable circuit component combination and parameter adjustment, the impedance of the entire system is matched.
[0037] The processor is MTK6762.
[0038] The telescopic antenna adapter board and the main board are connected by plug-in. By adopting the plug-in connection, a fast and stable connection can be achieved. This connection method has the advantages of easy disassembly and replacement, which is convenient for subsequent maintenance and upgrades.
[0039] In order to ensure a stable and reliable connection between the telescopic antenna adapter board and the mainboard, an elastic contact design can be used. This design can ensure that the connection remains stable and is not easy to loosen or fall off in harsh environments such as vibration or impact.
[0040] The interface design also needs to consider the installation angle and height of the antenna so that the position and direction of the antenna can be flexibly adjusted in actual use to achieve the best signal reception effect.
[0041] The working principle of the telescopic antenna adapter board mainly involves three processes: signal reception, processing and transmission. First, signal reception: When the telescopic antenna receives wireless signals, these signals are first transmitted to the antenna interface on the adapter board. Second, signal processing: On the adapter board, the signal first passes through a filter to filter out clutter and interference to improve signal quality. Subsequently, the signal is enhanced by an amplifier to ensure that it is not easily attenuated during subsequent transmission. The impedance matching network is responsible for achieving impedance matching between the antenna and the motherboard, reducing signal reflection and loss. Third, signal transmission: The processed signal is finally transmitted to the motherboard through the connector between the adapter board and the POS machine motherboard. The motherboard further processes and analyzes the received signal to complete functions such as payment and data transmission.
[0042] In the whole working process, the telescopic antenna adapter board plays a vital role. It can not only realize the stable connection between the telescopic antenna and the POS machine motherboard, but also effectively process and enhance the signal, thereby improving the signal receiving ability and stability of the POS machine.
[0043] The single-pole double-throw switch is any one of SS-12E05, KCD3, and E-TEN1122. These switches have their own characteristics in design. Some adopt a vertical toggle design, while others adopt a boat-type switch structure to adapt to different spaces and installation environments. In addition, their rated current, voltage, service life and other parameters are also different, and users can choose according to actual needs. In this embodiment, SS-12E05 is selected.
[0044] A single-pole double-throw switch has a moving end (i.e., "pole") and two fixed ends (i.e., "throws"). The moving end is usually connected to the incoming line of the power supply and is responsible for receiving electrical energy; while the two fixed ends are respectively connected to two different circuits or loads. When the switch is in a certain position, the moving end is connected to one of the fixed ends, so that the circuit or load obtains electrical energy; when the switch is switched to another position, the moving end is connected to the other fixed end, so that the other circuit or load obtains electrical energy. This switching function enables the single-pole double-throw switch to flexibly switch between different circuits or loads.
[0045] In mobile devices, the application of SPDT switches is particularly important. Mobile devices with built-in antennas and whip antennas compatible with POS terminals usually need to handle complex communication and data transmission tasks. SPDT switches can flexibly switch between built-in antennas and whip antennas to ensure that the device can maintain stable and efficient communication performance in different environments. For example, in areas with weak signal strength, the device can automatically switch to the whip antenna to enhance signal reception; in an environment with good signal strength, it can switch to the built-in antenna to save space and improve portability.
[0046] In addition, SPDT switches also play a key role in the safety of mobile devices. They can quickly cut off the power supply or switch to the backup power supply in an emergency to ensure the safety of the device and data. At the same time, by properly designing the trigger conditions and action sequence of the switch, it is also possible to achieve fine control of the device functions and improve user experience and convenience.
[0047] It is worth mentioning that the application of SPDT switches in mobile devices is also reflected in its durability and reliability. Since mobile devices usually need to be frequently moved and carried, the durability of their internal components is extremely high. SPDT switches are made of high-quality materials and precision manufacturing processes, have good shock and vibration resistance, and can maintain stable performance in harsh environments.
[0048] In some optional implementations, the mobile device of the utility model is provided with a communication module. The communication module further includes a baseband processing chip, a radio frequency module, a power amplifier, etc. The baseband processing chip is responsible for processing digital signals, encoding information into a format suitable for transmission, and decoding it at the receiving end. It is a key bridge connecting mobile devices and application software, ensuring the accurate transmission of information. The radio frequency module is responsible for converting the baseband processed signal into a radio frequency signal for wireless transmission through an antenna. The performance of the radio frequency module directly affects the stability and range of communication. The power amplifier provides sufficient energy for the radio frequency signal to ensure that the signal can be transmitted over long distances without distortion. Its working efficiency and stability directly determine the quality and efficiency of communication.
[0049] In some optional implementations, the mobile device of the utility model is also provided with a face recognition module. The face recognition module includes a camera, an image processor, etc. The camera is responsible for capturing the face image, and the image processor pre-processes the captured image, such as denoising, enhancing, etc., so as to better identify features, perform feature matching and identity confirmation. In this process, the compatible design of the built-in antenna and the telescopic antenna ensures that the device can stably transmit data in various environments, so that the face recognition module can complete the recognition task in real time and accurately.
[0050] It is worth mentioning that the application of face recognition module not only improves the security of transactions, but also greatly improves the convenience of transactions. In busy business scenarios, customers do not need to carry any additional equipment, they can complete the payment through face recognition, which greatly saves time. At the same time, for merchants, face recognition technology can also help them better manage customer information and improve service quality.
[0051] In some optional implementations, the mobile device of the utility model is also provided with a data encryption module and a data decryption module. The data encryption module encrypts the transmitted data to ensure that the data is not illegally stolen or tampered with during the transmission process. At the same time, the data decryption module is responsible for decrypting the received encrypted data and restoring the original data for the merchant to use. This encryption and decryption mechanism provides all-round protection for the merchant's transaction data and effectively prevents the risk of data leakage and illegal access.
[0052] In some optional implementations, the mobile device of the utility model is further provided with an identity authentication module. The identity authentication module includes but is not limited to biometric identification, password verification, and smart card identification. The comprehensive use of these identity authentication methods ensures that only authorized users can perform operations, greatly improving the security of transactions.
[0053] Biometric recognition technology verifies the user's identity by collecting biometric information such as fingerprints and facial features and comparing them with preset information. This technology is highly accurate and reliable and can effectively prevent identity theft and fraud.
[0054] Password verification requires the user to enter a preset password during the transaction. The complexity and length of the password can be set according to actual needs to meet different levels of security requirements. At the same time, the module also supports dynamic password technology, and the password generated for each transaction is different, further enhancing security.
[0055] Smart card recognition technology uses the chip information in the smart card for identity verification. Smart cards are usually bound to the user's personal information and account, so they are highly secure. By reading the information in the smart card, the user's identity can be verified quickly and accurately.
[0056] When conducting a transaction, the user first authenticates their identity through the identity verification module. Once the authentication is passed, the device will communicate with the POS machine through the built-in antenna or the telescopic antenna to complete the transmission and processing of transaction information. Throughout the process, the identity verification module always plays a key role to ensure the legitimacy and security of the transaction.
[0057] As the core of the entire device, the mainboard integrates various control chips and interface circuits, and is responsible for coordinating the work of various parts to realize data processing and transmission.
[0058] The SPDT switch is used to switch the use status of the built-in antenna and the telescopic antenna. When the SPDT switch is in a certain position, the built-in antenna is activated and put into use; when the SPDT switch is switched to another position, the telescopic antenna is connected to the mainboard through the telescopic antenna adapter board to replace the built-in antenna for signal reception.
[0059] The built-in antenna is designed inside the device, which has the characteristics of small size and good concealment. It connects to the built-in antenna interface on the mainboard to receive and send signals.
[0060] The whip antenna is a retractable antenna with a long reception range, suitable for areas with weak signals. It is connected to the adapter board through the whip antenna interface, and the adapter board communicates with the main board.
[0061] The telescopic antenna adapter board acts as a bridge, which can connect the telescopic antenna to the mainboard to ensure stable signal transmission.
[0062] RF IC is the key component responsible for processing RF signals. It can amplify, filter and modulate the received signals to meet the working requirements of POS terminals.
[0063] When the device is turned on and in standby mode, the mainboard receives the surrounding wireless signals through the built-in antenna. When payment is required, the POS machine issues an instruction, and the mainboard activates the corresponding communication module according to the instruction and processes the signal through the RF IC.
[0064] In terms of signal reception, the built-in antenna and the telescopic antenna play a key role. The built-in antenna can stably receive signals under normal conditions to ensure smooth payment operations. In the case of weak signals or interference, users can switch to the telescopic antenna mode by operating the single-pole double-throw switch. The telescopic antenna can capture signals more effectively and improve communication quality due to its longer receiving range and higher sensitivity.
[0065] In terms of signal processing, RF IC plays a core role. It can amplify, filter and modulate the received signal to extract useful information. At the same time, RF IC can also modulate and encode the transmitted signal to ensure that the signal can be accurately transmitted to the target device.
[0066] As the control center of the entire device, the motherboard is responsible for coordinating the work of various parts. It performs corresponding operations such as data transmission and payment processing according to the instructions and signal processing results of the POS machine. At the same time, the motherboard also has fault detection and self-protection functions, which can cut off the power supply or take other measures in time under abnormal circumstances to ensure the safe and stable operation of the device.
[0067] Through the design of the above embodiments, the utility model has the following beneficial effects: it is compatible with high appearance and strong signal (the pull-rod antenna can be removed in normal signal scenarios, retaining the high appearance, and the pull-rod antenna can be guaranteed to be used normally in weak signal scenarios); it is simple to operate; it has low cost; and it has stable signal communication without poor contact or intermittent signal.
[0068] The present invention is described according to specific embodiments, but those skilled in the art should understand that various changes and equivalent substitutions can be made without departing from the scope of the present invention. In addition, in order to adapt to specific occasions of the present invention technology, many modifications can be made to the present invention without departing from its protection scope. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all embodiments that fall within the scope of protection of the claims.
