Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0034] Figure 1 It is a schematic structural diagram of the communication module of the metering device provided by the embodiment of the present invention;

[0035] Figure 2 It is a specific structural diagram of the communication module of the metering device provided by the embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] In the following description, specific details such as specific system architectures and technologies are presented for purposes of illustration rather than limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from obscuring the description of the present invention.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings.

[0038] See Figure 1 , which shows a schematic structural diagram of a communication module of a metering device provided by an embodiment of the present invention. As Figure 1 shown, the communication module of the metering device includes: a first processing module 10, a second processing module 20, and a power management module 30;

[0039] The power management module 30 is used to supply power to the first processing module 10 and the second processing module 20;

[0040] The second processing module 20 is used for processing network communication protocols to achieve communication connection with a third-party platform;

[0041] The first processing module 10 is used to collect data of the metering device, perform logical processing on the data, and control the power management module 30 to start or stop supplying power to the second processing module 20.

[0042] In this embodiment, the first processing module 10 and the second processing module 20 can be two microprocessors respectively.

[0043] Specifically, the first processing module 10 is specifically used to implement data collection, metering, and application logic processing of the metering device. The metering device can be a device such as a water meter, an electric meter, a gas meter, etc. that needs to collect data in real time and report it to the cloud platform. Taking the electric meter as an example, the data of the metering device can include data such as electric energy, voltage, current, and power. The application logic can include anomaly detection, data calibration, etc.

[0044] The second processing module 20 is mainly used to process the process of data wireless transmission. Specifically, it is used to support complex network protocols such as TCP / IP, UDP, LWM2M protocols, etc.; implement modulation and demodulation of LTE (Long Term Evolution)-4G wireless signals, channel encoding and decoding, mutual conversion between digital signals and analog signals, and switching and compatibility of signals in different frequency bands, so as to achieve wireless communication with a third-party platform.

[0045] The power management module 30 is respectively used to manage the power supply of the first processing module 10 and the second processing module 20, and further realizes the on-demand wake-up and sleep of the second processing module 20.

[0046] Among them, the first processing module 10 is communicatively connected to the power management module 30 through a control signal interface and electrically connected to the power management module 30 through a power supply line PSC; the first processing module 10 is communicatively connected to the second processing module 20 through a communication line CL, and the power management module 30 and the second processing module 20 are electrically connected through a power supply line PSC.

[0047] As can be seen from the above embodiments, the above communication module adopts a dual-core system of the first processing module 10 and the second processing module 20, and can separately power off the second processing module 20 that processes the network communication protocol, thereby greatly reducing the power consumption of the communication module. At the same time, the dual-core independent system can also realize the functional decoupling of data processing and communication processing, thereby improving the processing efficiency of the communication process and meeting the real-time meter reading requirements of the metering device.

[0048] In a possible implementation manner, Figure 2 shows a specific structural schematic diagram of the communication module of the metering device provided in this embodiment, as Figure 2 shown, the first processing module 10 includes a microprocessor 11.

[0049] In this embodiment, the first processing module 10 is an ARM microprocessor, specifically a Cortex-M series microprocessor. This microprocessor 11 can support dynamic operating frequency adjustment, and the sleep current can be as low as 1.8 μA.

[0050] Exemplarily, the ARM microprocessor can support an independent operating frequency of 48 MHz.

[0051] In a possible implementation manner, the first processing module 10 further includes a Bluetooth Low Energy (BLE) radio frequency transceiver 12;

[0052] The Bluetooth Low Energy radio frequency transceiver 12 is connected to the microprocessor 11 and is used to periodically broadcast the status data of the metering device through the BLE protocol stack.

[0053] In this embodiment, the microprocessor 11 is connected to the Bluetooth Low Energy radio frequency transceiver 12 through a serial interface. The microprocessor 11 periodically broadcasts the status data of the metering device through the Bluetooth Low Energy radio frequency transceiver 12, and the cycle duration can be 2 seconds, and it supports near-field interaction, specifically including receiving Bluetooth connection requests from mobile terminals or gateways and triggering wake-up or data transmission.

[0054] As can be seen from the above embodiments, by using the timed wake-up broadcast of the Bluetooth protocol stack to measure the status data of the device instead of the traditional RTC alarm clock timed wake-up, the overall power consumption of the module can be minimized. Through the periodic wake-up method of the Bluetooth protocol stack, the current status of the metering device can be broadcast via Bluetooth, which is more convenient than the traditional metering device with only infrared communication. Traditional infrared communication requires short-distance visibility between the transmitting device and the receiving device, but the Bluetooth broadcast method in this embodiment can receive the status data of the metering device through a mobile phone or other Bluetooth devices within the Bluetooth broadcast range.

[0055] In this embodiment, the first processing module 10 can be triggered to wake up by an external magnet, touch, button operation, or Bluetooth connection, thereby improving the flexibility of user interaction.

[0056] In a possible implementation, referring to Figure 2 , the second processing module 20 includes a baseband unit 21 and a radio frequency unit 22;

[0057] The baseband unit 21 is used to process digital signals and network communication protocols;

[0058] The radio frequency unit 22 is used to perform analog-to-digital conversion processing of signals.

[0059] In this embodiment, the second processing module 20 includes a baseband unit 21, a radio frequency unit 22, an antenna switch module (ASM) 25, a duplexer Duplex26, a power amplifier (PA) 23, an LTE antenna diversity device 24, and a power supply unit 27;

[0060] Among them, ASM25 is responsible for switching the antenna path between different frequency bands or communication modes (such as different frequency bands of 4G LTE) to ensure that the signal can be correctly connected to the radio frequency circuit of the corresponding frequency band; it supports multi-band compatibility.

[0061] Duplex26 includes half-duplex and full-duplex. In the radio frequency communication part involved in the second processing module 20, the duplex technology determines the data transceiver method. Half-duplex means that at the same moment, the signal can only be transmitted unidirectionally, that is, either send data or receive data; full-duplex allows bidirectional data transmission at the same moment. The second processing module 20 uses the duplex technology to achieve efficient transceiver of LTE-4G wireless signals and ensure stable data transmission.

[0062] PA23 is responsible for amplifying the power of the transmitted signal so that the signal can be sent out with sufficient intensity to ensure that within a certain distance, the third-party platform can stably receive the data sent by the communication module, improving the coverage and reliability of communication.

[0063] The LTE antenna diversity combiner 24 is a module used to optimize the performance of multi-antenna systems, aiming to combat channel fading by receiving multi-path signals or signals from different antennas, and improve communication quality. The role of the LTE antenna diversity combiner 24 is to combine these signals from different paths, maximize the signal-to-noise ratio, and improve the anti-interference ability of the communication module.

[0064] The baseband unit Baseband21 is used to process network protocols, implement data encapsulation, channel encoding / decoding, and modulation / demodulation. The network protocols include TCP / IP, UDP, LwM2M, etc.

[0065] The radio frequency unit RF22 is the core module for realizing the conversion between digital signals and radio electromagnetic waves, and its functions cover key links such as signal modulation, frequency conversion, and power amplification.

[0066] The power supply unit 27 receives power supply from the power management module 30 and delivers electrical signals to each unit of the second processing module 20.

[0067] Specifically, in the signal reception stage, the antenna receives electromagnetic wave signals in space; the antenna diversity combiner combines the signals received by multiple antennas (such as the main antenna and the diversity antenna), and after boosting the signal-to-noise ratio, inputs the signals to the low-noise amplifier. After the signals are amplified by the low-noise amplifier, they are sent to the radio frequency unit 22 through Duplex26 or ASM25. The radio frequency unit 22 performs analog-to-digital conversion on the signals and sends the digital baseband signals to the baseband unit 21, and the baseband unit 21 demodulates, decodes, and processes the protocol for the digital baseband signals.

[0068] In a possible implementation, the first processing module 10 is specifically configured to:

[0069] If it detects that the idle entry condition is triggered, it enters the idle state and sends a first power-off instruction to the power management module 30 in the idle state;

[0070] If it detects that the sleep entry condition is triggered, it enters the sleep state, reduces its own operating frequency in the sleep state, and sends a first power-off instruction to the power management module 30;

[0071] If it detects that the first wake-up condition is triggered, it enters the idle state and increases the operating frequency of the first processing module 10 in the idle state;

[0072] If it detects that the second wake-up condition is triggered, it enters the active state, increases the operating frequency of the first processing module 10 in the active state, and sends a first power supply instruction to the power management module 30;

[0073] The power management module 30 is specifically configured to:

[0074] Stop power supply to the second processing module 20 according to the first power outage instruction;

[0075] Start power supply to the second processing module 20 according to the first power supply instruction.

[0076] In this embodiment, in the active state, both the first processing module 10 and the second processing module 20 work normally. In the idle state, the first processing module 10 works normally and the second processing module 20 is powered off. In the sleep state, the first processing module 10 operates at a lower working frequency and the second processing module 20 is powered off.

[0077] Specifically, the initial power-on state of the communication module is the active state. In the active state, both the first processing module 10 and the second processing module 20 are working normally. At this time, the second processing module 20 is responsible for modulation and demodulation of wireless signals, encoding and decoding, and transmission and reception of radio frequency signals. The first processing module 10 is responsible for logical operations of metering data of metering devices and application logic processing.

[0078] When it is detected that the idle entry condition is triggered in the active state, it means that the communication module does not need to communicate with the third-party platform at this time. Then the first processing module 10 sends the first power outage instruction to the power management module 30. The power management module 30 stops power supply to the second processing module 20 based on the first power outage instruction. The second processing module 20 is powered off and stops working. At this time, only the first processing module 10 performs normal local service logic, thereby reducing the power consumption of the communication module.

[0079] When it is detected that the sleep entry condition is triggered when the communication module is in the active state or the idle state, its normal working frequency is reduced to the second working frequency, and the data processing cycle is lengthened to reduce the power consumption of the first processing module 10; at the same time, it is also necessary to send the first power outage instruction to the power management module 30. If the power management module 30 detects that the second processing module 20 is already powered off (the communication module is in the idle state) at this time, it will ignore the first power outage instruction; if the second processing module 20 is not powered off (the communication module is in the active state), it will perform a power-off operation on the second processing module 20 based on the first power outage instruction. The communication module achieves an ultra-low power consumption effect in the sleep state, and the standby power consumption is less than 2 μA.

[0080] When the communication module is in the sleep state or the idle state, if it detects the second wake-up instruction that needs to communicate with the third-party platform, it sends the first power supply instruction to the power management module 30. The power management module 30 starts to supply power to the second processing module 20 based on the first power supply instruction, and the second processing module 20 is powered on and works. At this time, it is also necessary to adjust the working frequency of the first processing module to the normal working frequency.

[0081] When the communication module is in the sleep state, if a first wake-up instruction that requires the first processing module 10 to work is detected, only the working frequency of the first processing module 10 is increased to the normal working frequency to ensure the processing of the normal services of the first processing module 10.

[0082] In a possible implementation manner, the first processing module 10 is specifically configured to:

[0083] If a reply offline instruction sent by a third-party platform is detected, it is determined that the idle entry condition is triggered.

[0084] In this embodiment, the metering device actively reports data to the third-party platform through the communication module, or uploads data after receiving a meter reading instruction issued by the third-party platform. When the third-party platform issues a reply offline instruction, it indicates that the third-party platform temporarily does not need to perform meter reading operations on the metering device. Therefore, the second processing module 20 is in an idle state afterwards, and the power management module 30 can be directly controlled to stop supplying power to the second processing module 20 to reduce the energy consumption of the communication module and make the communication module enter the idle state.

[0085] In a possible implementation manner, the first processing module 10 is specifically configured to:

[0086] If no external trigger signal and the status data of the metering device periodically broadcast are detected within a preset time after detecting a reply offline instruction sent by the third-party platform, it is determined that the sleep entry condition is triggered.

[0087] In this embodiment, the external trigger signal includes physical interaction signals such as magnet induction, button, touch operation, etc., and a connection request signal initiated by a Bluetooth host. The status data of the metering device is periodically broadcast by the Bluetooth low energy radio frequency transceiver 12.

[0088] Specifically, when the communication module is in the active state and a reply offline instruction from the third-party platform is detected, if no physical interaction signals such as magnet induction, button, touch operation, etc., a connection request signal initiated by the Bluetooth host, and the status data of the metering device periodically broadcast by the Bluetooth low energy radio frequency transceiver 12 are detected within a preset duration before and after the occurrence of this instruction, it is determined that the sleep entry condition is triggered. The first processing module 10 can control the power management module 30 to stop supplying power to the second processing module 20, and at the same time reduce its own working frequency to the second working frequency, thereby minimizing the energy consumption of the communication module to the greatest extent.

[0089] When the communication module is in the idle state, if no external trigger signal and the status data of the metering device periodically broadcast are detected for a continuous first preset duration, it is determined that the sleep entry condition is triggered again.

[0090] In a possible implementation manner, the first processing module 10 is specifically configured to:

[0091] If within the preset time after detecting the reply offline instruction sent by the third-party platform, no external trigger signal, the status data of the metering device broadcast regularly, and the event triggered by the metering data exceeding the corresponding preset threshold are detected, it is determined that the sleep entry condition is triggered;

[0092] If when the communication module is in the idle state, no external trigger signal, the status data of the metering device broadcast regularly, and the event triggered by the metering data exceeding the corresponding preset threshold are detected for a first preset duration, it is determined that the sleep entry condition is triggered.

[0093] In a possible implementation manner, the first processing module 10 is specifically configured to:

[0094] If an external trigger signal, the status data of the metering device broadcast regularly, or there is metering data reaching the preset threshold is detected in the sleep state, it is determined that the first wake-up condition is triggered;

[0095] If a meter reading instruction sent by the third-party platform is detected in the sleep state or the idle state, or an emergency event that needs to be reported to the third-party platform is detected, it is determined that the second wake-up condition is triggered.

[0096] In this embodiment, after the first processing module 10 wakes up from the sleep state due to the first wake-up condition, it enters the idle state. If no external trigger signal, the status data of the metering device broadcast regularly, and the event triggered by the metering data exceeding the corresponding preset threshold are detected within the first preset duration after entering the idle state, it enters the sleep state again.

[0097] When the first processing module 10 detects that it needs to be applied to the second processing module 20, for example, a meter reading instruction sent by the third-party platform is detected, or an emergency event that needs to be reported to the third-party platform is detected, it changes to the active state, so as to ensure the normal operation of the communication module.

[0098] Among them, the emergency event may include events such as leakage and strong magnetic attack that may cause the metering device to malfunction.

[0099] As can be seen from the above embodiments, in this embodiment, through the independent first processing module 10 and second processing module 20, the communication module can be hierarchically managed in three working states, minimizing the running time of the high-power active state to the greatest extent. Moreover, when the communication module is in the idle state, it can independently process local tasks through the first processing module 10, avoiding frequent wake-up of the second processing module 20; the active state is started on demand to ensure the real-time nature of data communication. In addition, when an emergency occurs in the metering device, it can be quickly woken up and enter the active state to ensure the priority transmission of key data (such as alarms), so that the communication module of the metering device can minimize energy consumption to the greatest extent on the premise of ensuring the real-time nature of task processing.

[0100] In a possible implementation manner, the power management module 30 is a power management integrated circuit.

[0101] In this embodiment, the power management module 30 is a PMIC (Power Management Integrated Circuit), and the PMIC is a highly integrated chip mainly used for power management in electronic devices, including: voltage conversion: converting the input voltage (such as the battery voltage) into the voltage levels required by different modules; dynamic power supply control: supplying power to the processor, radio frequency module, etc. on demand, for example, turning off the power of unnecessary modules in the sleep state; power consumption optimization: reducing energy consumption through dynamic voltage / frequency regulation; protection function: providing protection mechanisms such as overvoltage, overcurrent, and short circuit to improve system reliability.

[0102] Specifically, the PMIC is used to precisely control the power supply of the second processing module 20 to achieve ultra-low sleep power consumption and fast wake-up.

[0103] In a second aspect, an embodiment of the present invention provides a control method for a communication module of a metering device, which is applied to the first processing module 10 of the communication module as described above, and includes:

[0104] S101: If it is detected that the idle entry condition is triggered, enter the idle state, and send a first power-off instruction to the power management module 30 in the idle state;

[0105] S102: If it is detected that the sleep entry condition is triggered, enter the sleep state, and reduce its own working frequency in the sleep state, and send a first power-off instruction to the power management module 30; the first power-off instruction is used to instruct the power management module 30 to stop supplying power to the second processing module 20;

[0106] S103: If it is detected that the first wake-up condition is triggered, enter the idle state, and increase the working frequency of the first processing module 10 in the idle state;

[0107] S104: If it is detected that the second wake-up condition is triggered, enter the active state, increase the operating frequency of the first processing module 10 in the active state, and send a first power supply instruction to the power management module 30; the first power supply instruction is used to instruct the power management module 30 to start supplying power to the second processing module 20.

[0108] In a possible implementation manner, the specific implementation process of S101 includes:

[0109] If it is detected that a reply offline instruction sent by a third-party platform is received, it is determined that the idle entry condition is triggered.

[0110] In a possible implementation manner, the specific implementation process of S102 includes:

[0111] If no external trigger signal and the status data of the metering device broadcast regularly are detected within a preset time after it is detected that a reply offline instruction sent by a third-party platform is received, it is determined that the sleep entry condition is triggered.

[0112] In a possible implementation manner, the specific implementation process of S103 includes:

[0113] If an external trigger signal, the status data of the metering device broadcast regularly, or there is metering data reaching a preset threshold is detected in the sleep state, it is determined that the first wake-up condition is triggered.

[0114] In a possible implementation manner, the specific implementation process of S104 includes:

[0115] If a meter reading instruction sent by a third-party platform is detected in the sleep state or the idle state, or an emergency event that needs to be reported to the third-party platform is detected, it is determined that the second wake-up condition is triggered.

[0116] In a third aspect, an embodiment of the present invention provides a metering device, which includes the communication module as described in the first aspect above.

[0117] As can be seen from the above embodiments, the application program of the communication module provided in this embodiment is simple to develop. In the metering device, it can replace the traditional MCU + module or semi-Open module. The traditional MCU code can be translated to the first processing module 10, and it can be started and awakened independently. At the same time, it supports the one-key power-off of the second processing module 20, thereby reducing the standby power consumption of the communication module in the sleep state. In addition, the communication module provided in this embodiment is compatible with various network protocols and supports mainstream Internet of Things platforms such as OneNET and CTWing, truly realizing seamless docking and rapid development. Secondly, the communication module provided in this embodiment integrates communication and metering, and there is no need to additionally set up an MCU. The second processing module 20 for communication and the first communication module for metering achieve functional decoupling, and can be restarted, awakened, and powered off independently, thereby minimizing the power consumption of the communication module. When the communication module is in the sleep state, the sleep current reaches 1.8 μA, and the overall average power consumption of the entire communication module is reduced to 8 μA.
