Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to an online upgrading method and device for a wireless vibration sensor. Background Art

[0002] LoRaWAN is a low-power, long-distance wireless communication protocol, but the communication transmission rate is relatively slow, and the maximum data packet generally does not exceed 200B. Online upgrade of wireless sensors refers to remotely updating the firmware of deployed sensors through wireless communication technology to improve functions, fix vulnerabilities or optimize performance.

[0003] In the existing technology, the firmware package for upgrading is usually sent to the sensor that needs to be upgraded through the wireless communication technology used by the sensor. Then the sensor installs the firmware by itself, that is, the firmware upgrade is completed.

[0004] However, when using wireless communication protocols with faster communication rates (WiFi, 4G, etc.) for firmware package transmission, the power consumption is high, which will put pressure on the battery life of the sensor. If low-power protocols such as LoRaWAN are used for long-term packet transmission, in industrial sites, dozens or hundreds of sensors are usually bound to one gateway. As long as a sensor is in the firmware package transmission state, it will occupy the channel for a long time, resulting in the interruption of the transmission of other sensor status data; and long-term firmware package transmission will increase the consumption of battery power.

[0062] The following specific embodiments are used to describe in detail the technical solution of the present invention and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0063] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0064] Figure 1 FIG. 1 is a schematic diagram showing the principle of splitting the upgrade file package in an embodiment of the present application. Figure 1 As shown in the figure, a basic version of the firmware package will be burned into the Flash (flash memory) of the MCU (microcontroller unit) in advance when the sensor leaves the factory; the subsequent upgrade firmware uses a differential algorithm (with corresponding algorithm tools) to extract differences based on the basic version of the firmware to reduce the firmware size; the extracted difference package is divided into multiple small packages according to a fixed protocol format.

[0065] For example, the basic working principle of a wireless vibration sensor is to detect the vibration of an object through a built-in accelerometer or vibration sensor. The accelerometer can measure the acceleration changes of an object in different directions, thereby calculating the amplitude, frequency and direction of the vibration. These data are transmitted to a server or cloud platform for analysis and processing via wireless communication technology (LoRaWAN). In order to extend battery life, the sensor will sleep for a long time, and then wake up regularly according to the configuration information, collect, calculate, and transmit data after waking up, and enter sleep mode again after the transmission is completed.

[0066] For example, based on the working principle of the wireless vibration sensor, it can be obtained Figure 2The online upgrade method of a wireless vibration sensor shown is applied to the sensor end. The method in this embodiment may include the following steps:

[0067] Step 201: Receive the pre-upgrade version number and corresponding upgrade information replied by the server.

[0068] Exemplarily, before executing step 201, the sensor uploads the current firmware version number to the server when uploading vibration data to the server; and receives a confirmation packet replied by the server, wherein the confirmation packet includes the current pre-upgrade version number.

[0069] In this embodiment, according to a specific communication protocol, all vibration sensors on site will upload the current firmware version number to the server software each time they upload vibration data; when the server software replies to the confirmation package, it will also reply with the current pre-upgrade version number.

[0070] In this embodiment, the upgrade information includes: the total number of upgrade file packages, and the serial number of each upgrade file package; wherein the upgrade file package refers to: a difference package obtained by using a differential algorithm to perform difference extraction based on a pre-stored basic firmware package, and the difference package is split into multiple small packages according to a fixed protocol format.

[0071] In this embodiment, when firmware upgrade is not required, the version number uploaded by the sensor is consistent with the version number replied by the server software; when an online upgrade is required (i.e., the server software detects that the version uploaded by the sensor is inconsistent with the pre-upgrade version, and an upgrade file of the pre-upgrade version already exists on the software), the server software will reply with the pre-upgrade version number and corresponding upgrade information (i.e., the total number of upgrade file packages, etc.).

[0072] Step 202, after saving the pre-upgrade version number and the corresponding upgrade information, enter the dormant state.

[0073] In this embodiment, after receiving the information that the server software needs to upgrade, the sensor will not immediately obtain the upgrade file, but will save the information and then go into sleep mode normally.

[0074] Exemplarily, before executing step 202, the sensor pre-determines whether the current firmware version number is consistent with the current pre-upgrade version number in the confirmation package; if they are consistent, the pre-upgrade version number and the corresponding upgrade information are not saved and the sensor enters a dormant state; if they are inconsistent, the pre-upgrade version number and the corresponding upgrade information are saved.

[0075] Step 203: If the state is switched from the dormant state to the awake state, at least one upgrade file package number to be obtained is attached to the vibration data uploaded to the server each time.

[0076] In this embodiment, after the next wake-up, based on the saved information (whether to upgrade, upgrade file size, etc.), the data is collected and when the vibration data is uploaded, if the upgrade file needs to be obtained, the serial number of the upgrade file package to be obtained will be attached to the uploaded vibration data (for example, based on the saved information, only one package of upgrade files will be obtained in sequence).

[0077] Step 204: Receive the upgrade file package fed back by the server and save the upgrade file package.

[0078] In this embodiment, the server software replies with a confirmation package based on the data information uploaded by the sensor and attaches a corresponding upgrade file package; after receiving the upgrade file package data, the sensor updates and saves the upgrade information and saves the upgrade file package (when the upgrade file has not been fully acquired).

[0079] In this embodiment, if the reception of all upgrade file packages is not completed, the upgrade file packages are saved and no package assembly process is performed until the reception of all file upgrade packages is completed.

[0080] Step 205: If all upgrade file packages have been received, the upgrade file packages are assembled to obtain differential firmware.

[0081] In this embodiment, after the sensor obtains all the upgrade file packages (the total number of upgrade file packages is included in the initial upgrade information), it will automatically assemble the upgrade files into differential firmware.

[0082] Step 206: Perform restoration processing based on the pre-stored basic firmware package and the differential firmware to obtain the firmware to be upgraded.

[0083] In this embodiment, the basic firmware package stored in the Flash is combined and restored to the firmware to be upgraded (saved and a rollback path is provided) according to a specific algorithm.

[0084] Step 207, automatically completing the upgrade of the firmware to be upgraded, and updating the current firmware version number.

[0085] In this embodiment, the sensor completes the firmware upgrade by itself, and uploads the firmware version number after the upgrade is completed during the next data upload.

[0086] Exemplarily, after the upgrade of the firmware to be upgraded is automatically completed and the current firmware version number is updated, the upgrade information is cleared and the dormant state is entered.

[0087] In this embodiment, the pre-upgrade version number and the corresponding upgrade information replied by the server are received; after saving the pre-upgrade version number and the corresponding upgrade information, the dormant state is entered; if the dormant state is switched to the awake state, at least one upgrade file package serial number that needs to be obtained is attached to each vibration data uploaded to the server; thus, there is no need to spend an extra period of time to transmit the firmware package. The upgrade file package fed back by the server is received, and the upgrade file package is saved; if all upgrade file packages are received, the upgrade file package is processed to obtain differential firmware; the firmware to be upgraded is obtained according to the pre-stored basic firmware package and the differential firmware; the upgrade of the firmware to be upgraded is automatically completed, and the current firmware version number is updated. Therefore, the package processing can be performed based on the basic firmware package and the upgrade file package sealed by the sensor before leaving the factory, which greatly reduces the size of the transmitted firmware package, avoids channel occupation, and reduces the power consumption of the sensor.

[0088] For example, based on the working principle of the wireless vibration sensor, it can be obtained Figure 3 Another online upgrade method of a wireless vibration sensor shown is applied to a server side. The method in this embodiment may include the following steps:

[0089] Step 301: Receive vibration data uploaded by a sensor, and obtain the current firmware version number contained in the vibration data.

[0090] In this embodiment, the server continuously receives the vibration data uploaded by the sensor, and obtains the current firmware version number contained in the vibration data when parsing the vibration data. That is, the sensor side will continuously report the current firmware version number to the server.

[0091] Step 302, compare the current firmware version number with the current pre-upgrade version number to obtain a comparison result.

[0092] In this embodiment, the server can determine whether an upgrade is required based on the current firmware version number and the current pre-upgrade version number. If the two are different, it means that an upgrade is required, and if the two are the same, no upgrade is required.

[0093] Step 303: If the comparison result is inconsistent, the pre-upgrade version number and corresponding upgrade information are replied to the sensor.

[0094] In this embodiment, in combination with step 302, when an upgrade is required, the server replies to the server with the upgrade version number and corresponding upgrade information.

[0095] Step 304: If the comparison result is consistent, the process ends.

[0096] In this embodiment, if upgrading is not required, there is no need to start the upgrading process and the process ends.

[0097] Exemplarily, after replying the pre-upgrade version number and corresponding upgrade information to the sensor, the method also includes: receiving vibration data uploaded by the sensor, and obtaining at least one upgrade file package serial number that needs to be obtained and is attached to the vibration data; and sending the corresponding upgrade file package to the sensor according to the upgrade file package serial number.

[0098] In this embodiment, the corresponding upgrade file packages are sent to the sensor in accordance with the upgrade file package sequence number by multiple sending, so that after the sensor completes the reception of all the upgrade file packages, the upgrade file packages are assembled to obtain differential firmware, and the upgrade is automatically completed based on the pre-stored basic firmware package and the differential firmware after the firmware to be upgraded is obtained.

[0099] This embodiment can use a differential algorithm to split the upgrade firmware into differential firmware based on the factory-cured basic firmware package, greatly reducing the amount of transmitted data. By splitting the upgrade file into a large number of upgrade file packets according to a specific communication protocol, and sending them to the sensor in multiple times through data reply packets, and using a low-power wireless communication protocol to reduce the transmission power consumption of wireless sensors, the firmware delivery does not cause excessive power consumption and does not occupy the channel for a long time to cause communication congestion of other sensors.

[0100] This embodiment can compress the size of the upgraded firmware as much as possible and utilize the normal data interaction process of the sensor to transmit the firmware data for upgrading to each sensor node in packets, thereby effectively avoiding data signal occupation and reducing battery consumption.

[0101] For example, Figure 4 FIG. 1 is a flow chart of an online upgrade method for a wireless vibration sensor in an embodiment of the present application. Figure 4 As shown, after waking up the sensor, collect vibration / temperature data; query the upgrade information; determine whether to obtain the upgrade package, if so, upload the corresponding upgrade file package number in the vibration / temperature data, if not, upload the vibration / temperature data with the firmware version number to the server; receive the server reply; detect whether the received upgrade file package has been received, if not, save the upgrade file and update the upgrade information, and enter the dormant state, if so, assemble the differential firmware; component upgrade firmware save and roll back; firmware upgrade; determine whether the upgrade is successful, if so, clear the upgrade information and update the firmware version number, and enter the dormant state, if not, roll back and upgrade again. After uploading the vibration / temperature data with the firmware version number to the server, determine whether it needs to be upgraded, if so, save the upgrade information, if not, enter the dormant state.

[0102] For example, Figure 5FIG. 1 is a flow chart of an online upgrade method applied to a server in an embodiment of the present application. Figure 5 As shown, first receive sensor data and determine whether an upgrade is needed. If so, determine whether to issue the upgrade file. If not, reply with a confirmation package. If an upgrade file is issued, reply with a confirmation package to upgrade the corresponding file package. If the upgrade file is not issued, reply with a confirmation package upgrade information.

[0103] Although this embodiment performs online upgrade based on a low-power wireless communication protocol, the firmware file will not be sent to occupy the channel for a long time, thereby preventing other sensors from sending and receiving data normally. By using data reply packets to sub-packetize and transmit the firmware file for upgrading, there is no need to send the firmware for a long time alone, thus avoiding a large amount of battery power consumption.
