In the embodiments of the present disclosure, these operations or steps may be performed serially; these operations or steps may also be performed in parallel; or some of these operations or steps may be performed.

[0052] A sensor device is a device that rapidly senses changes in an analog physical quantity and converts them into data for transmission and processing. Sensor devices sense various physical information, such as temperature, humidity, light, pressure, displacement, sound, and images, convert these signals into electrical signals, and then transmit these signals to other devices via wireless communication. Sensor devices are characterized by their small size, low power consumption, low cost, and ease of deployment. They are widely used in environmental monitoring, agricultural production, smart homes, industrial automation, healthcare, and other fields.

[0053] A Wireless Sensor Network (WSN) is a wireless network formed by distributed sensors. It uses a large number of sensors to obtain and aggregate environmental information of different times, places, and types in nature, and then processes and transmits it to the outside.

[0054] The speed and power consumption of existing IoT devices, which rely on communication between sensor devices, are divided into three levels: high-speed IoT, medium-speed IoT, and low-speed IoT. High-speed IoT is primarily carried by technologies such as 5G (5th Generation Mobile Communication Technology), 5G-Advanced (5G-A), 5G Enhanced Mobile Broadband (5G Enhanced Mobile Broadband), and WiFi 6. Medium-speed IoT is currently primarily carried by technologies such as 4G LTE UE-Category 1 (4G Cat. 1), 3G (3rd Generation), and 2G (2nd Generation). Low-speed IoT is primarily carried by technologies such as NB-IoT (Narrow Band Internet of Things), LoRaWAN (Long Range Wide Area Network), and Bluetooth Low Energy (BLE).

[0055] Currently, the problems and shortcomings of related technologies are as follows:

[0056] 1. Existing sensor equipment technologies mostly rely on medium- and high-speed IoT technologies such as 5G, 4G, and WiFi 6, as well as low-speed IoT technologies such as NB-IoT, LoRaWAN, and BLE, resulting in complex communication solutions.

[0057] 2. Existing IoT sensors are highly dependent on the internet. If the internet connection is interrupted, the devices may not function properly. This is especially true in outdoor scenarios such as environmental monitoring in remote areas, where most areas lack 4G or 5G mobile network access, making it difficult to upload monitoring data using existing communication technologies.

[0058] 3. A low-speed or unstable network environment may limit the performance of the device, resulting in the inability to transmit data collected by the sensor or low-quality transmission.

[0059] 4. The overall monitoring system of the hydropower generation group includes numerous high dams and large reservoirs, requiring the deployment of a large number of sensors for status monitoring. However, due to the long transmission distance required, for example, the total length of the dam is over 2,300 meters, the existing low-power IoT technology communication range is usually only tens of meters, making long-distance communication difficult.

[0060] 5. The communication modules of existing sensor equipment are complex. In harsh outdoor environments, the failure rate of the communication modules is high, making it difficult to cope with harsh and extreme environments.

[0061] 6. The cost of using existing IoT communication modules is relatively high, and the overall cost is relatively high in the scenario of large-scale deployment of disposable, non-recyclable sensor devices.

[0062] In order to solve the above-mentioned technical problems, the present application provides a data transmission method, device, electronic device, storage medium and product. On the one hand, the sensor device and the information collection device realize data communication by combining radio frequency identification technology with the environmental Internet of Things. Not only can the sensor device still upload its own data in an unstable network environment, thereby improving work efficiency and solving the problem of data reading dependence on the network, but data reading does not require a dedicated reader, thereby reducing hardware costs. On the other hand, during the data reading process, power is supplied by the radio frequency signal sent by the information collection device. That is to say, the data communication process does not require the use of a built-in battery or other power supply. Since a built-in power supply and complex electronic components are not required to ensure data communication, the cost of the sensor device is saved.

[0063] The data transmission method provided in the embodiments of the present application is described in detail below.

[0064] Figure 1 This is a flowchart of a data transmission method provided by an embodiment of the present application, which is applied to sensor devices, such as Figure 1As shown, the method may include the following steps.

[0065] Step 101: upon receiving a radio frequency identification signal transmitted by an information collection device, activate the radio frequency tag.

[0066] In an embodiment of the present application, a radio frequency identification (RFID) signal is used for data reading.

[0067] In the embodiment of the present application, a radio frequency tag is integrated into the sensor device.

[0068] Optionally, the sensor device includes a radio frequency tag, a sensor module, a processor module, a wireless communication module, and a power module. The radio frequency tag includes a chip and an antenna. The chip is used to store environmental data, and the antenna is used to receive and send radio frequency signals. The sensor module is used to obtain various information in the physical world, such as environmental data; the processor module is used to process and analyze the data collected by the sensor module, such as data filtering, feature extraction, data compression, etc.; the wireless communication module is used to transmit the data processed by the processor module to other devices via wireless communication; for example, data communication is performed through radio frequency identification (RFID) technology; the power module is used to provide energy for the sensor device, usually using batteries or solar cells.

[0069] It should be noted that the RFID tag and the processor module communicate through a specific interface. The RFID tag is used to collect the energy of the RFID signal and convert it into electrical energy to power itself, the sensor module, and the processor module. The processor module can write data to the RFID tag module or read its status information.

[0070] In an embodiment of the present application, the sensor device can be pre-set at a designated location of the device to be tested, and the sensor device can also be set in the target area by being scattered by a drone.

[0071] In embodiments of the present application, the sensor device may be an ambient IoT sensor that collects wireless signals from the surrounding environment, such as radio wave energy generated by 5G, Wi-Fi, and Bluetooth, to power the sensor device, enabling the sensor device to operate continuously without batteries. This reduces long-term maintenance costs and improves the sustainability of the sensor device.

[0072] In some embodiments, Figure 1 The data transmission method in this paper is applied to sensor nodes in WSN.

[0073] In the embodiment of the present application, the RFID tag is an electronic tag that uses radio frequency identification technology to store and transmit data.

[0074] In some embodiments, the RFID tag may be a passive tag that does not include a battery and relies on receiving radio frequency signals emitted by an information collection device to obtain energy to work. In response to receiving a radio frequency identification signal, the radio frequency tag is activated.

[0075] In other embodiments, the RFID tag may be a semi-active tag. The RFID tag is usually in a dormant state and relies on its own battery to maintain the operation of the internal circuit. The RFID tag will only be activated when it enters the radio frequency field of the information collection device.

[0076] Step 102: Modulate the environmental data stored in the sensor device onto a radio frequency signal through the radio frequency tag to obtain a response request.

[0077] In this embodiment of the present application, environmental data may include: water level data, water quality data, meteorological data, and dam safety data. Water level data includes water level height and water level change rate; water quality data includes pH, dissolved oxygen, turbidity, conductivity, ammonia nitrogen, total phosphorus, and total nitrogen; meteorological data includes rainfall, temperature, wind speed, and direction; and dam safety data includes dam displacement, seepage pressure, and crack monitoring.

[0078] In some embodiments, the environmental data may also include location data. For example, the sensor device may have a built-in Beidou module for real-time positioning to obtain its own location data.

[0079] In other embodiments, the environmental data may also include water flow velocity, water temperature stratification, etc.

[0080] It can be understood that in the embodiment of the present application, there are multiple sensor devices, and the sensor devices are of different types. In actual applications, the number and type of sensor devices are selected as needed and set in designated locations or areas.

[0081] In some embodiments, step 102 may include: modulating the environmental data onto a radio frequency signal according to a preset modulation rule through the antenna of the radio frequency tag to obtain a response request.

[0082] In some embodiments, to ensure transmission security, step 102 may include: encrypting the environmental data, modulating the encrypted environmental data onto a radio frequency signal through a radio frequency tag, and obtaining a response request.

[0083] In other embodiments, the environmental data stored by the sensor device is stored in encrypted form.

[0084] Step 103: Send the response request to the information collection device.

[0085] In an embodiment of the present application, the information collection device reads environmental data based on the modulated radio frequency signal; during the data reading process, the radio frequency identification signal is used to power the sensor device.

[0086] It should be noted that since the power is supplied by the radio frequency signal sent by the information acquisition device, the data communication process does not require the use of a built-in battery or other power supply. The power battery of the sensor device is only used for the sensor module to obtain environmental data and write environmental data into the RFID tag. Since data communication does not require battery power, the sensor device can be equipped with a smaller battery and does not require complex electronic components to ensure data communication, or a battery of the same size can be used to provide the sensor with a longer life, saving the cost of the sensor device.

[0087] In some embodiments, step 103 may send the response request to the information collection device via Bluetooth and perform subsequent data transmission.

[0088] In some embodiments, after step 103, the data transmission method may include: pushing all or batches of environmental data within the monitoring period of the sensor device to an RFID tag, and then sending the data to an information collection device via the RFID tag, so that the information collection device can remotely read the data. The monitoring period may be pre-set, and the environmental data within the monitoring period may be stored in a storage device such as a memory card.

[0089] To sum up, in the data transmission method in the embodiment of the present application, the sensor device and the information collection device realize data communication through the combination of radio frequency identification technology and environmental Internet of Things. Not only can the sensor device still upload its own data in an unstable network environment, thereby improving work efficiency and solving the problem of data reading dependence on the network, but also data reading does not require a dedicated reader, reducing hardware costs; on the other hand, during the data reading process, power is supplied by the radio frequency signal sent by the information collection device, that is, the data communication process does not require the use of a built-in battery or other power supply. Since a built-in power supply and complex electronic components are not required to ensure data communication, not only the cost of the sensor device is saved, but also the workload of replacing the battery of the sensor device or recharging it is reduced, thereby reducing the cost of the Internet of Things communication module.

[0090] Figure 2 This is a flowchart of another data transmission method provided by an embodiment of the present application. Figure 2 As shown, the method is applied to an information collection device, and the method may include the following steps.

[0091] Step 201: Transmit a radio frequency identification signal to a sensor device.

[0092] In the embodiment of the present application, step 201 enables the sensor device to activate the RFID tag when receiving the RFID signal, and modulate the environmental data stored in the sensor device onto the RFID signal through the RFID tag to obtain a response request; the RFID signal is used for data reading.

[0093] Step 202: When a response request is received from the sensor device, environmental data is read according to the modulated radio frequency signal.

[0094] During the data reading process, the radio frequency identification signal is used to power the sensor device.

[0095] It should be noted that since the power is supplied by the radio frequency signal sent by the information acquisition device, the data communication process does not require the use of a built-in battery or other power supply. The power battery of the sensor device is only used for the sensor module to obtain environmental data and write monitoring data to the RFID tag. Since there is no need for a built-in power supply and complex electronic components to ensure data communication, the cost of the sensor device is saved.

[0096] In some embodiments, step 202 may include: decoding the modulated radio frequency signal according to a preset modulation rule through the antenna of the information collection device to obtain environmental data.

[0097] In some embodiments, step 202 may include: upon receiving a response request returned by the sensor device, demodulating and decrypting the modulated radio frequency signal to obtain environmental data.

[0098] Exemplarily, the demodulation process is opposite to the modulation process of the tag. According to the modulation rule adopted, the amplitude, frequency or phase change of the received RF signal is converted into digital data, which is then decoded and processed to finally obtain the environmental data stored in the RF tag.

[0099] To sum up, in the data transmission method in the embodiment of the present application, the sensor device and the information collection device realize data communication through the combination of radio frequency identification technology and environmental Internet of Things. Not only can the sensor device still upload its own data in an unstable network environment, thereby improving work efficiency and solving the problem of data reading dependence on the network, but also data reading does not require a dedicated reader, reducing hardware costs; on the other hand, during the data reading process, power is supplied by the radio frequency signal sent by the information collection device, that is, the data communication process does not require the use of a built-in battery or other power supply. Since a built-in power supply and complex electronic components are not required to ensure data communication, not only the cost of the sensor device is saved, but also the workload of replacing the battery of the sensor device or recharging it is reduced, thereby reducing the cost of the Internet of Things communication module.

[0100] Figure 3 This is a flowchart of another data transmission method provided by an embodiment of the present application. Figure 3 As shown, the method may include the following steps.

[0101] Step 301: The information collection device transmits a radio frequency identification signal to a sensor device.

[0102] The method of this step has been described in the aforementioned step 201 and will not be repeated here.

[0103] Step 302: When the sensor device receives the RFID signal, it converts the electromagnetic wave of the RFID signal into electrical energy through the antenna using the principle of electromagnetic induction.

[0104] In the embodiment of the present application, the RFID signal is used for data reading.

[0105] In an embodiment of the present application, the radio frequency tag includes a chip, an antenna and an energy storage circuit. The energy storage circuit is connected to the chip and the antenna respectively. The antenna is used to transmit and receive radio frequency signals, and the chip is used to store environmental data.

[0106] Exemplarily, the chip may be a microcontroller (MCU), which is used to control the RFID tag to enter different working states, such as sleep, wake-up, data reading and sending, etc.

[0107] For example, when receiving an RFID signal, the antenna converts the RFID signal into an electric current through the principle of electromagnetic induction, providing energy and data signals for the tag; when transmitting the modulated RFID signal, the antenna loads the data processed inside the RFID tag onto the RFID signal and radiates it out.

[0108] Step 303: The sensor device uses electrical energy to charge the energy storage circuit, so that the energy storage circuit can power the chip during the data reading period.

[0109] Exemplarily, the energy storage circuit is used to convert the high-frequency alternating radio frequency signal received by the antenna into a direct current voltage to power the internal circuit of the radio frequency identification tag.

[0110] For example, the energy storage circuit is a rectifier circuit composed of a Schottky barrier diode. It uses the unidirectional conductivity of the diode to rectify the alternating positive and negative RF signals into a unidirectional DC signal. After filtering and voltage stabilization, it provides a stable power supply for subsequent circuits, thereby powering the chip during the data reading period.

[0111] For example, the energy storage circuit is a capacitor circuit. It uses the energy storage characteristics of the capacitor to convert the radio frequency signal received by the antenna into DC power and store it in the capacitor, providing a stable power supply for the circuit in the radio frequency identification tag, and then powering the chip during the data reading period.

[0112] For example, when an RFID tag enters the RF field of a reader, the antenna receives the RF signal and converts it into electrical energy to power the chip. After receiving energy, the chip transmits the data stored in it to the RFID tag via the antenna. The RFID tag then transmits the received data to a back-end system for processing. The back-end system can be a monitoring data analysis system or a cloud server, which is not limited in the present embodiment.

[0113] In this way, the sensor device interacts with the information collection device by reflecting the environmental signal. Using backscattering technology, the sensor device does not need to actively transmit signals and the power consumption is extremely low.

[0114] In some embodiments, after step 303, the data transmission method may further include:

[0115] Sub-step A1: When data reading is completed and no radio frequency identification signal is received within a preset time period, the control chip enters a dormant state.

[0116] In an embodiment of the present application, the preset time length can be 5 minutes, or the preset time length can be 30 seconds, which can be set according to actual needs.

[0117] Through the above technical solution, since the control chip is put into sleep mode when no radio frequency identification signal is received for a long time, the power consumption of the sensor device can be reduced, thereby ensuring the long-term operation of the sensor device.

[0118] Step 304: The sensor device obtains a preset modulation rule.

[0119] In the embodiment of the present application, the modulation rules are pre-stored in the radio frequency tag.

[0120] In some embodiments, the modulation rules may include: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK).

[0121] Step 305: The sensor device modulates the environmental data onto a radio frequency signal through the antenna according to a modulation rule to obtain a response request.

[0122] In the embodiment of the present application, the radio frequency tag includes an antenna for transmitting and receiving radio frequency signals.

[0123] In some embodiments, step 304 may include using load modulation to change the load impedance of the tag antenna to change the amplitude, phase, or frequency of the RF signal reflected back to the reader, thereby adding data to the RF signal. For example, in amplitude modulation, the amplitude of the reflected signal is changed to represent different data bits.

[0124] In some embodiments, step 305 may include:

[0125] Sub-step 3051: Use a preset data compression algorithm to compress the environmental data into a smaller volume.

[0126] Sub-step 3052: modulate the compressed environmental data onto a radio frequency signal through the radio frequency tag.

[0127] In the embodiment of the present application, the data compression algorithm may include: Huffman coding, arithmetic coding, compression algorithm based on data redundancy elimination technology, etc. Among them, the compression algorithm based on data redundancy elimination technology may include: block-based and content-based redundancy elimination algorithms.

[0128] In this way, by compressing the environmental data, the amount of data in the transmission process can be greatly reduced, thereby reducing the energy and time required for data transmission.

[0129] Step 306: The sensor device sends the response request to the information collection device.

[0130] The method of this step has been described in the aforementioned step 103 and will not be repeated here.

[0131] Step 307: Upon receiving the response request, the information collection device obtains a preset demodulation rule.

[0132] In the embodiment of the present application, the demodulation rules are pre-stored in the information collection device.

[0133] It should be noted that the demodulation rule in the information collection device corresponds to the modulation rule in the sensor device.

[0134] Step 308: The information collection device decodes the modulated radio frequency signal according to the demodulation rule to obtain environmental data.

[0135] In some embodiments, after step 308, the data transmission method may further include:

[0136] Sub-step 309: The information collection device pre-processes and stores the environmental data; and uploads the processed data and the identification of the sensor device to the monitoring data analysis system so that the monitoring data analysis system can evaluate the performance of each sensor device.
