Technical Field

[0001] The utility model relates to the technical field of dual-mode communication, in particular to an integrated dual-mode communication module. Background Art

[0002] With the continuous development of smart grids and the Internet of Things, the requirements for communication technology have also increased. Traditional communication methods usually only support one communication protocol and cannot meet the communication needs in different scenarios. In order to solve this problem, an integrable dual-mode communication module has been proposed. This module can support two different communication protocols at the same time, provide a unified interface and control, and thus improve the communication efficiency of the equipment.

[0003] Dual-mode communication modules are widely used in the power field, especially in power carrier communication and radio frequency communication. Dual-mode communication modules can be applied to smart grids, using power carrier communication technology to transmit high-speed data on power lines, and using radio frequency communication technology to communicate with wireless sensor nodes, to achieve remote monitoring, data collection and control of power transmission and distribution networks; dual-mode communication modules can also be used in electricity meters and smart metering to achieve remote meter reading, data collection and energy management functions.

[0004] Although dual-mode communication modules have broad application prospects and can provide more flexible and efficient communication solutions, there are also some problems. Traditional dual-mode communication modules usually require two independent hardware modules, which will take up more hardware space; dual-mode communication modules have high power consumption and may require additional power to support RF and power carrier communications, resulting in increased power consumption and reduced efficiency; at the same time, integrating multiple communication technologies may lead to limited hardware resources, and it is necessary to weigh various functional and performance requirements.

[0005] Therefore, it is necessary to develop an integrable dual-mode communication module to integrate multiple different functions into one module to reduce manufacturing costs; at the same time, integrating multiple communication technologies in one module can share resources and power supply, improve power consumption efficiency and system performance.

[0036] In this embodiment, the control chip is the core component of the entire integrated dual-mode communication module, responsible for controlling each functional unit of the entire module, and the control chip model is CC1350F128RHBR.

[0037] The RF unit and the power carrier unit are electrically connected to the control chip through the SPI interface. The RF unit includes an RF amplifier, a mixer, and a filter 2 which are electrically connected in sequence. The RF amplifier is electrically connected to the control chip, and the filter 2 is electrically connected to the selector, which is connected to the external antenna. The RF amplifier is used to amplify the signal sent by the control chip and enhance it to the required power level. The mixer is used to mix the RF signal with the local oscillation signal to generate an intermediate frequency signal. The filter is used to filter and shape the mixed intermediate frequency signal; the signal enters the selector, and the selector selects different antennas for communication according to the requirements of the communication mode.

[0038] The power carrier unit includes a demodulator, a filter 3, and a coupler that are electrically connected in sequence. The demodulator is electrically connected to the control chip. The coupler type is a voltage coupler and is connected to the power line. The output signal of the control chip is demodulated by the demodulator, and the demodulator is used to convert the digital signal output by the control chip into an analog signal; the demodulated signal is immersed in the filter to remove the noise and unnecessary frequency components in the signal, and improve the quality and accuracy of the signal; the filtered signal is immersed in the coupler to couple the signal of the power carrier unit into the power line. Conversely, the signal on the power line can also be coupled into the power filter unit through the coupler, and after being filtered by the filter and demodulated by the demodulator, it is received by the control chip.

[0039] The radio frequency unit and the power carrier unit adopt two different communication modes. Under the unified control of the control chip, the communication mode can be flexibly switched to improve communication efficiency and flexibility.

The sensor unit includes a temperature sensor and a humidity sensor, which are electrically connected to the control chip. The temperature sensor and the humidity sensor can measure the temperature and humidity in the environment respectively, and the corresponding sensors transmit the detected electrical signals to the control chip.

The transceiver receives the signal, and the filter 1 is responsible for filtering the received signal. The filtered signal is transmitted to the control chip through the digital processing unit.

[0042] In the present invention, the radio frequency unit is also electrically connected to a selector, which is electrically connected to the external antenna. The selector type is a multiplexer, which switches signals under the control of the control chip and is connected to the external antenna.

[0043] The integrable dual-mode communication module also includes a communication interface unit, which is electrically connected to the control chip through a UART interface. The communication interface unit is responsible for the communication between the integrable dual-mode communication module and other systems or devices, and can realize external access and flexible function expansion. The communication interface unit is provided with a digital interface, an analog interface, and a debugging interface.

[0044] The power supply unit provides the required power for the entire integrated dual-mode communication module, and the capacitor unit is used to store and release electrical energy to provide a stable voltage or current for the module.

The indicator light includes a power indicator light, a communication indicator light, and a fault indicator light. The power indicator light is used to indicate the power status of the integrated dual-mode communication module. When the module is working normally, the power indicator light will light up; the communication indicator light is used to indicate the communication status of the module. When the module is communicating, the communication indicator light flashes; the fault indicator light is used to indicate the fault status of the module. When the module fails, the fault indicator light will light up.
