Detailed ways

In order to facilitate the understanding of the invention, the invention will be described in detail below in conjunction with the accompanying drawings and embodiments of the specification. However, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the invention and are not intended to Limit the protection scope of the present invention.

In the description of the present invention, "module" and "processor" may include hardware, software, or a combination of both. A module can include hardware circuits, various suitable sensors, communication ports, and memory, and can also include software parts, such as program codes, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and/or signal processing functions. The processor can be implemented in software, hardware, or a combination of the two. The non-transitory computer-readable storage medium includes any suitable medium that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random access memory, and so on. The term "A and/or B" means all possible combinations of A and B, such as only A, only B, or A and B. The term "at least one of A or B" or "at least one of A and B" has a meaning similar to "A and/or B" and may include only A, only B, or A and B. The terms "a" and "this" in the singular form may also include the plural form.

In the prior art, devices that use NB-IOT modules for communication are kept in the dormant state of the power-saving mode PSM in order to reduce power consumption, cannot receive and send data/signals/commands, etc., and cannot achieve remote interaction, while the connection state of the PSM And the idle state can receive and send data/signals/commands, etc., but under the status change of the PSM mode, the integrity of the received and sent data cannot be guaranteed, and the two states continue to maintain high power consumption. Thus, the device low-power-consumption interaction solution of the present invention is provided. The implementation of the solution of the present invention will be described below in conjunction with an embodiment of the application scenario shown in FIG. 1. Because NB-IOT is built on a cellular network and only consumes about 180kHz of bandwidth, it can be directly deployed on a GSM network, a UMTS network or an LTE network to reduce deployment costs and achieve smooth upgrades. When using NB-IOT for communication, it can effectively communicate with the base station. Realize data interaction. Among them, a portable device that uses an NB-IOT module to communicate. The portable device can be an electronic device that has its own battery component or a rechargeable battery component that can be carried around, and it also has an NB-IOT module to communicate with the base station. Communication, sending uplink instructions (or uplink data/signals, etc.) to the base station. The portable device may further include a smart humidity thermometer, etc., specifically, for example, it can be used as an indoor humidity and temperature detection device, it can also be connected to a server through a network to achieve linkage with home appliances such as air conditioners, and it has an NB-IOT module. The group communicates with the base station. In this embodiment, the base station is connected to the application server of the Internet through the operator's core network, and the application server can be connected to remote control terminals, such as various mobile terminals or non-mobile terminals: mobile phones, pads, laptops, PCs and many more. These remote control terminals can interact with the application server, send control instructions (control data/signals, etc.) to the application server via the Internet, and then the application server sends the control instructions/data/signals to the base station via the operator’s core network. The base station serves as the downlink The instructions are delivered to the portable device through the NB-IOT module. When portable devices use NB-IOT modules for communication, that is, NB-IOT devices, they support three working modes: power saving mode PSM (Power Saving Mode), discontinuous reception mode DRX (Discontinuous Reception), and extended discontinuous reception mode eDRX (Extended DRX); Among them, NB-IOT devices use the most power-saving PSM mode. There are three working states in the power-saving mode PSM: connected state, idle state, sleep state; connected state and idle state can receive downlink data , But the power consumption is high; the downlink data is not received in the sleep state, but the power consumption is the lowest. As shown in Figure 6, the comparison of different power consumption of NB-IOT equipment in different modes, in order to increase the standby time, NB-IOT equipment in PSM mode, because most of the time is in the dormant state, the device does not receive downlink data and cannot be controlled remotely. If the terminal is set to it, it cannot interact; and if it is to ensure that it can receive and send complete data/signals/commands, that is, normal interaction, that is, the DRX mode can ensure the success rate of the downlink commands, but because the DRX mode is in an idle state, its power consumption (Hundreds of microamperes) is much higher than the sleep state (microampere level), which will increase the power consumption and reduce the standby time. Therefore, the DRX mode is used, that is, in the DRX mode, the NB-IOT module will not enter the sleep state. But the power consumption is significantly higher than the power consumption when using the PSM mode. For example, a certain NB-IOT device consumes 167mA in the connected state, 0.4mA in the idle state, 3μA in the sleep state, the connected state is maintained for 100ms, the idle state is maintained for 3s, and the sleep period is 1 hour, then PSM is used. The annual power consumption of the device is: [(167*0.1+0.4*3+0.003*3596.9)/3600]*24*365≈69.8mAh; while in DRX mode, the annual power consumption of the device is: [(167* 0.1+0.4*3599.9)/3600]*24*365≈3544.5mAh. It can be seen that the power consumption of the device in DRX mode is much higher than that in PSM mode.

The solution of the present invention, as an example of the application scenario shown in Figure 1, the portable device uses the NB-IoT communication process, for example: Uplink: the portable device reports data to the base station through the NB-IOT module, and transmits it to the application through the operator’s core network Server, the application server pushes data to the remote control terminal. Downlink: The user operates on the remote control terminal, and the data is sent to the application server through the network, and the data is sent to the portable device through the NB-IOT module through the operator's core network and base station.

Further, in the solution of the present invention, the process of the interaction between the remote control terminal and the NB-IOT device:

When the user needs to set/set/modify the settings of the portable device, manually trigger the portable device to switch from the sleep state of the PSM mode to the DRX mode. The DRX mode lasts for a preset length of time, such as N minutes. Within the preset time, the user sends the downlink instruction after completing the issuance of the setting instruction. Within the preset time, the user can immediately receive the feedback that the portable device has received and executed the setting, so that the user can determine the downlink instruction. Whether to execute or not, and after the scheduled time expires, the device will switch from DRX mode to PSM mode, which ensures that the device remains in a low power consumption state for a long time.

More specifically, it is further described with reference to the schematic diagram of an embodiment of the interaction process of the device low-power interaction method of the present invention shown in FIG. 2.

The user needs to reset the portable device such as modification through the remote control terminal. The following is an example of a mobile phone and a thermometer and hygrometer.

The corresponding application software APP that can interact with the thermometer and hygrometer or set it is installed in the mobile phone. Click on the APP, select the thermometer and hygrometer to modify the settings, and display the prompt "The device needs to be powered on again" on the mobile phone, indicating that the thermometer and hygrometer are in the dormant state of the PSM, so if you want to control it, you need to power it on again. The user can manually power on the thermometer and hygrometer at the end of the thermometer and hygrometer. In addition, it can also be powered on by other methods, which will not be listed here. After sending the prompt message (after powering on the thermometer and hygrometer), the mobile phone will start timing for N minutes at the same time, and the prompt "setting will be completed within N minutes" can also be displayed on the mobile phone screen, and the user is here for the preset time of N minutes For example, you can select or fill in the settings such as modifying settings in the control menu of the APP, and send down instructions to the thermometer and hygrometer according to the settings, instructing it to execute the settings according to the modified settings, and the user can set it through the remote control. Send the downlink command regularly within the last N minutes. After manually powering on, the thermometer and hygrometer with NB-IOT communication module enters the DRX mode from the original sleep state under the PSM, and the timer can last for N minutes in the DRX mode. Downlink instructions are transmitted to the application server via the Internet, reach the base station via the operator's core network, and reach a thermohygrometer with NB-IOT communication function based on NB-IOT. The thermometer and hygrometer complete the modification setting after receiving the downlink instruction, and feedback in real time the return instruction that has completed the modification setting as an uplink instruction, which is reported to the base station, and then transmitted to the application server via the operator's core network, and then pushes real-time feedback via the Internet The downlink command to the mobile phone. As a result, the user can judge whether the remote interactive control is successfully completed according to the feedback uplink command. If it is, the mobile phone displays a prompt "setting successful", otherwise, the mobile phone prompts "setting failed" when the duration of N minutes is over, and can prompt User "please reset" etc. At the end of the thermometer and hygrometer, regardless of whether it receives a downlink command or executes the modification setting (modification setting is completed or the modification setting cannot be completed, etc.) and reports the corresponding uplink command (modification is completed or the modification cannot be completed), as long as the If it lasts for N minutes in DRX mode, it will automatically switch to the sleep state under PSM to reduce power consumption, unless there is an interactive situation that changes the settings when the power is turned on again next time. The thermometer and hygrometer are operating normally. Power-on again, referred to as power-on, includes: resetting the device to exit the PSM mode through a physical operation, or exiting the PSM mode through other similar methods. Therefore, it is possible to reduce the increase in power consumption caused by the demand of the downlink instruction through the interaction in the low power consumption state of the NB-IOT device, and to determine whether the downlink instruction is executed in real time. In this way, through the example of the improved remote modification setting solution provided by the present invention, assuming that the annual power consumption is less than 69.8mAh+0.4*180/3600*12=72.2mAh at a frequency set once a month, which is much lower than Use the DRX mode of 3544.5mAh; the improved solution of the present invention, in the entire N minutes set time, the remote control terminal judges whether the device has completed the modification through the uplink command, and after N minutes, the device exits the DRX mode, and the remote control terminal stops sending downlink at the same time Instruction and prompt failure, so the remote control terminal can judge in real time whether the real-time interaction is successful, and does not increase excessive power consumption.

The following describes the solution of the present invention through the main flow chart of an embodiment of the portable device end of the device low-power interaction method of the present invention shown in FIG. 3.

Step S310: Re-power on the NB-IOT device by receiving an instruction from the remote control terminal to re-power on the NB-IOT device, and the NB-IOT device enters the DRX mode from the low power consumption mode and keeps the DRX mode in the DRX mode for a preset time. time. Specifically, the NB-IOT device maintains operation in a sleep state in the PSM mode before receiving the power-on instruction; the NB-IOT device is manually powered on after receiving the power-on instruction; After the NB-IOT device is powered on, it switches from the sleep state of the PSM mode to the DRX mode, and starts timing in the DRX mode, and the duration of the DRX mode is the preset time. In one embodiment, the remote control terminal is various terminal devices that can be operated by the user and connected to the network. When the user needs to control and interact with a portable device (NB-IOT device) with NB-IOT communication function at the remote end of the network connection, such as a thermometer and hygrometer, he can set (modify) by operating the APP on the remote control terminal. Setting of temperature and humidity meter, etc.). The remote control terminal can prompt the user that the portable device needs to be powered on again. On the portable device side, the portable device can be manually powered on again. After power-on, the portable device has the NB-IOT communication function. The NB-IOT module can switch from the sleep state under the original power saving mode PSM to DRX mode, and start timing. The DRX can last for N minutes (that is, a preset time: "preset time"). Within the last N minutes, wait to receive the downlink command, so as to reset or modify the setting according to the instructions of the modification setting of the downlink command, and return to the set or unset return command after the modification is completed. For example, report uplink instructions. Among them, the discontinuous reception DRX mode itself is a high power consumption state, but it can ensure the immediacy and completeness of data, instructions, signals, etc. receiving and sending.

In step S320, the NB-IOT device determines whether to receive a setting instruction from the remote control terminal within the preset time to determine whether to modify the setting. Specifically, within the preset time, the remote control terminal sets the NB-IOT device, and periodically sends a downlink instruction for setting the NB-IOT device to the NB-IOT device; Within the predetermined time, the NB-IOT device is waiting to receive the downlink instruction; if the downlink instruction is received, the modification setting of the corresponding NB-IOT device is completed according to the downlink instruction, and the setting completion result is sent The return instruction is sent to the remote control terminal; if the downlink instruction is not received, no setting is made and no return instruction is sent; wherein the return instruction is an uplink instruction. Further, the downlink instruction includes: the remote control terminal sends an instruction to modify the settings to the application server, the application server sends to the base station via the operator's core network, and the base station sends the instruction as a downlink instruction via the NB-IOT network. NB-IOT device; further, the uplink instruction includes: the NB-IOT device uploads the return instruction to the base station via the NB-IOT network, and the base station transmits the data via the base station to the application server via the operator’s core network. Push to the remote control terminal. In one embodiment, within a preset time, such as N minutes (e.g., 3 minutes), if the remote control terminal such as a terminal device (mobile phone, etc.) is prompted to re-power on the NB-IOT device such as a thermometer and hygrometer, the timer will be preset Set a time of N minutes to prompt the user to complete the setting of the device (thermometer and hygrometer) within N minutes, and the user uses the mobile phone and other terminal devices for remote control to start the thermometer and hygrometer within N minutes. Modification or setting of various functions and other settings, and sending the downlink command, that is, the setting command, to the thermometer and hygrometer at regular intervals within N minutes. Downlink commands can be sent regularly, for example, once every n seconds, and last for a preset time, that is, N minutes. The portable device NB-IOT, such as a thermometer and hygrometer, can wait to receive the setting command (downlink command) within N minutes of timing. Once received, it will execute the modification or setting operation indicated by the command, and the execution will be complete. The return instruction of the result of real-time execution of the setting operation can be fed back to the user. Here, when the user's setting is completed, the setting instruction is sent to the thermometer and hygrometer immediately, and the feedback of the completion of the setting is very fast, that is, real-time command and real-time feedback, so that the interaction between the two parties is similar to directly modifying or setting the device. The return command is reported to the base station and returned to the remote control terminal as an uplink command. The remote control terminal determines whether the setting is completed or not completed according to the execution completion result in the uplink command.

Step S330: After waiting for the DRX mode of the NB-IOT device to continue for the preset time, the NB-IOT device enters a low power consumption mode. Specifically, after waiting for the NB-IOT device to continue in the DRX mode for the preset time, regardless of whether the modification setting is made and whether a return instruction is sent, the NB-IOT device is reentered into the PSM mode Hibernation. That is, return to the low power consumption state of the power saving PSM mode that the device has maintained for a long time. In one embodiment, a portable device with NB-IOT function, such as a thermometer and hygrometer, after being in the DRX mode for N minutes, regardless of whether the device has received a downlink instruction to modify the settings, regardless of whether the device executes the modified settings Whether the completion result is successful, and whether the device has reported an uplink command as a feedback to the setting command of the remote control terminal (mobile phone, etc.), once it reaches the continuous N minutes, such as 3 minutes, the portable device will switch back from DRX mode In the sleep state under PSM, the device is running normally, waiting for the next power-on, setting, etc.

Correspondingly, the following describes the solution of the present invention through the main flow chart of an embodiment of the remote control terminal of the device low-power interaction method of the present invention shown in FIG. 4.

In step S410, it is prompted to re-power on the NB-IoT device to modify settings and start counting for a preset time. Specifically, before prompting to power on the NB-IoT device again, the NB-IoT device maintains operation in the sleep state of the PSM mode; the counting a preset time is for the corresponding NB-IoT device to restart After entering the DRX mode after power-on, the DRX mode lasts for a preset time length. In one embodiment, the remote control terminal is various terminal devices that can be operated by the user and connected to the network. When the user needs to control and interact with a portable device (NB-IOT device) with NB-IOT communication function at the remote end of the network connection, such as a thermometer and hygrometer, he can set (modify) by operating the APP on the remote control terminal. Setting of temperature and humidity meter, etc.). The remote control terminal can prompt the user that the portable device needs to be powered on again. On the portable device side, the portable device can be manually powered on again. After power-on, the portable device has the NB-IOT communication function. The NB-IOT module can switch from the sleep state under the original power saving mode PSM to DRX mode, and start timing. The DRX can last for N minutes (that is, a preset time: "preset time"). Within the last N minutes, wait to receive the downlink command, so as to reset or modify the setting according to the instructions of the modification setting of the downlink command, and return to the set or unset return command after the modification is completed. For example, report uplink instructions. Among them, the discontinuous reception DRX mode itself is a high power consumption state, but it can ensure the immediacy and completeness of data, instructions, signals, etc. receiving and sending. Furthermore, within a preset time such as N minutes (e.g. 3 minutes), if the remote control terminal such as a terminal device (mobile phone, etc.) is prompted to re-power on the NB-IOT device such as a thermometer and hygrometer, the preset time is counted as N Minutes, prompt the user to complete the setting of the device (thermometer and hygrometer) within N minutes.

Step S420: Send the instruction to modify the settings to the NB-IoT device at regular intervals. Specifically, the modified setting is periodically sent to the NB-IoT device through a downlink instruction to execute the modified setting corresponding to the instruction to modify the setting. In addition, within a continuous preset time, the downlink instruction is retransmitted in a continuous timing cycle until the subsequent continuous preset time reaches to determine whether an uplink instruction is received and the instruction indicates that the setting is successful. In one embodiment, the user starts to modify or set various functions and settings of the thermometer and hygrometer within a continuous period of N minutes through the mobile phone and other terminal devices used for remote control, and sends the downlink periodically within the continuous period of N minutes. The command is the setting command and sent to the thermometer and hygrometer. Downlink commands can be sent regularly, for example, once every n seconds, and last for a preset time, that is, N minutes. The portable device NB-IOT, such as a thermometer and hygrometer, can wait to receive the setting command (downlink command) within N minutes of timing. Once received, it will execute the modification or setting operation indicated by the command, and the execution will be complete. The return instruction of the result of real-time execution of the setting operation can be fed back to the user. Here, when the user's setting is completed, the setting instruction is sent to the thermometer and hygrometer immediately, and the feedback of the completion of the setting is very fast, that is, real-time command and real-time feedback, so that the interaction between the two parties is similar to directly modifying or setting the device. The return command is reported to the base station and returned to the remote control terminal as an uplink command. The remote control terminal determines whether the setting is completed or not completed according to the execution completion result in the uplink command. The result of the execution completion may be the successful modification or setting according to the instructions of the downstream command, or the modification or setting failure due to various reasons.

Step S430: Determine whether a return instruction of the NB-IoT device according to the modified setting instruction is received within the preset time; wherein, if it is determined that the return instruction is received and all If the instruction indicates success, it prompts that the modification setting is successful; if the preset time has arrived, it is determined that the return instruction has been received and the instruction indicates a failure or the return instruction has not been received after the preset time has elapsed , It prompts failed to modify the settings. Specifically, within the preset time, waiting to receive an uplink instruction from the NB-IoT device indicating that the execution setting is completed and the return is completed (the return instruction is an instruction for the user to perform a modification or setting operation through the remote control terminal feedback of). If it is determined within the preset time that the returned uplink command is received and the uplink command indicates success, then it is prompted that the modification setting has been successful. However, if after the preset time is reached, it is determined that the return uplink command is received but the uplink command indicates that it failed, or the return uplink command has not been received, then it is prompted to modify the setting has failed, and the user is prompted to choose whether Re-prompt to manually power on the NB-IoT device again and switch from the sleep state of PSM mode to DRX mode to execute the modified settings again; if yes, manually power on the NB-IoT again, and re-execute the above remote control interaction process. Wherein, the downlink instruction includes: the remote control terminal sends an instruction to modify the settings to the application server, the application server sends to the base station via the operator's core network, and the base station sends the instruction as a downlink instruction via the NB-IoT network. NB-IoT device; the uplink instruction includes: the NB-IoT device uploads the return instruction to the base station via the NB-IoT network, and the base station transmits the data to the application server via the base station via the operator’s core network, and the application server pushes the data to Remote control terminal. In one embodiment, a portable device with NB-IOT function, such as a thermometer and hygrometer, after being in the DRX mode for N minutes, regardless of whether the device has received a downlink instruction to modify the settings, regardless of whether the device executes the modified settings Whether the completion result is successful, and whether the device has reported an uplink command as a feedback to the setting command of the remote control terminal (mobile phone, etc.), once it reaches the lasting N minutes, such as 3 minutes, the portable device (thermometer, etc.) Switch from the DRX mode to the sleep state under PSM, and wait for the next power-on, setting, etc. Correspondingly, the user of the remote control terminal (mobile phone, etc.) also waits for the feedback of the portable device within N minutes. If the mobile phone or other terminal receives the reported uplink instruction, and the instruction resolves to be modified or set successfully, then After completing the interactive process, a prompt message can be displayed to the user, such as "setting successful". And if the mobile phone and other end received the uplink command within N minutes, but it is resolved that the modification or setting failed due to various reasons, and the downlink command of the setting operation has been retransmitted regularly for N minutes. If it still fails after N minutes, the interactive process ends and a prompt message can be displayed to the user, such as "setting failed". However, if the downlink instruction is not received at all within the last N minutes, that is, no feedback for the user setting is obtained, it also indicates that this interaction has failed, and a prompt message can be displayed to the user "setting failed". Furthermore, in the case of a setting failure, after the duration of N minutes has been reached, a message prompting the user can also be displayed, prompting the user whether to re-power on the portable device, so that it will switch from the sleep state of the power saving mode PSM to Interact again in DRX mode to re-set the device. That is, re-execute the process.

On the portable device side, the portable device can be manually powered on again. After power-on, the portable device has the NB-IOT communication function. The NB-IOT module can switch from the sleep state under the original power saving mode PSM to DRX mode, and start timing. The DRX can last for N minutes (that is, a preset time: "preset time").
