Description

Narrowband internet of things upgrade method and device, and system

Technical field

The present disclosure relates to the field of narrowband Internet of Things, and more particularly to a narrowband Internet of Things upgrade method and apparatus, and system.

Background technique

The Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. Built on a cellular network, NB-IoT consumes only about 180KHz of bandwidth and can be deployed directly on a GSM (Global System for Mobile Communications) network, a UMTS (Universal Mobile Telecommunication System) network, or LTE ( Long Term Evolution, 3GPP Long Term Evolution) network to reduce deployment costs and achieve smooth upgrades.

NB-IoT has four characteristics: First, wide coverage will provide improved indoor coverage. In the same frequency band, NB-IoT gains 20dB more than the existing network, which is equivalent to the ability to increase the coverage area by 100 times. With the ability to support massive connections, NB-IoT can support 100,000 connections in one sector, supporting low latency sensitivity, ultra-low device cost, low device power consumption and optimized network architecture. Third, lower power consumption. The standby time of the NB-IoT terminal module can be as long as 10 years; the fourth is the lower module cost, the enterprise expects a single connected module to not exceed 5 US dollars.

The NB-IoT uses the license band and can be deployed in the inband, guard band, or independent carrier mode to coexist with the existing network. Focusing on the Low Power Wide Coverage (LPWA) Internet of Things (IoT) market, NB-IoT is an emerging technology that can be used globally. Because of its low power consumption, wide coverage, low cost, and large capacity, NB-IoT can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, and smart agriculture. Operators have begun NB-IoT network layout, and the NB (Narrow Band) network-based IoT terminal will be applied on a large scale, and the NB module will gradually become popular.

According to this, the NB module supporting NB-IoT will be more and more widely used in the Internet of Things, and its upgrade requirements will be an inevitable business function.

Detailed ways

In view of the current situation, the upgrade of the NB module is very important. The existing upgrades generally use OTA upgrade or manual disassembly upgrade, but have the following defects:

1. Due to the limitation of NB bandwidth, the size of the OTA (Over-the-Air Technology) upgrade package is very strict. A slightly larger package requires a longer download time, so for the upgrade, the limit is compared. Many, especially for dead devices, it is difficult to complete the upgrade by downloading the full version of the package.

2. The general integration environment of the NB module is quite special. It is difficult to manually disassemble and upgrade, or directly link to upgrade.

The disclosure is further described below in conjunction with the drawings.

Referring to FIG. 1A, a block diagram of a narrowband Internet of Things upgrade system is provided in the present disclosure. The system of the present disclosure includes a cloud, an upgrade tool device that communicates through the HTTP protocol and the cloud, and an upgrade request transmitted through the COAP protocol and the cloud. The NB module, the NB module integrates a short-distance transmission chip, and has a normal system and a backup system.

FIG. 1B is a schematic diagram of a communication protocol between various parts in a narrowband Internet of Things upgrade system; as shown in the figure, in order to better support the NB module upgrade function in different environments, the communication protocol of the upgrade package tool device and the NB module is used. A relatively broad customization, that is, a protocol that is compatible with low power consumption and reliable transmission, may be applicable. The transmission protocol between the cloud and the NB module is applicable to the COAP protocol. The protocol used in the existing download package is also the HTTP protocol. To support the HTTP protocol, the adaptability is not very strong on many products for limited memory and computing power. . The use of upgrade notifications and upgrade downloads separately allows the NB module to not integrate too powerful protocol support. The communication between the cloud and the upgrade package tool device can adopt the HTTP protocol. The upgrade package tool can preset the upgrade package, or download the upgrade package from the cloud in real time, which increases flexibility.

Referring to FIG. 2, the present disclosure proposes a narrowband Internet of Things upgrade method, the method comprising:

Step 130: The NB module receives the version file sent by the proximity upgrade tool device by using the short-distance transmission module.

Step 140: The NB module performs version upgrade according to the received version file.

Referring to FIG. 3A, in the embodiment of the present disclosure, before the NB module in step 130 receives the version file sent by the proximity upgrade tool device by using the short-distance transmission module, the method further includes:

Step 120: Turn on the short-distance transmission module.

After the NB module described in step 140 performs version upgrade according to the received version file, the method further includes:

In step 150, the proximity transmission module is turned off.

The short-distance transmission module includes a short-distance transmission chip.

In the embodiment of the present disclosure, before the opening the proximity transmission module, the method further includes:

Step 110, polling to check whether there is an upgrade request;

In the case that it is determined to be upgraded, the step of turning on the proximity transmission module is performed as described in step 120.

After the transmitting chip of step 120, the method further includes: implementing a matching between the upgrade tool device and the NB module;

Referring to FIG. 3B, it is a multi-party interaction diagram in the system; the multi-party interaction process includes:

Part of the search function, matching function, transmission function in the tool device, and signal transmission service in another part of the NB module, NB module matching service, and NB module transmission service, the specific steps are as follows:

Step 210, after an upgrade request, the normal system starts the proximity transmission chip to the working state.

Step 220: After the NB module starts the proximity transmission chip, the chip starts to send the heartbeat broadcast signal.

Step 230, the tool sets the search function to start the heartbeat signal search.

Step 240, after searching, initiate a matching request according to the content of the protocol in the signal.

Step 250: The proximity communication chip in the NB module receives the matching request, and then performs matching according to the carried matching field.

In step 260, if the matching fails, the corresponding information is returned, and the heartbeat signal is continuously sent. If the matching is successful, the connected link is established.

Step 270: After the connection link is established, the tool device sends the version file through the protocol, and the short-distance transmission chip in the NB module receives the corresponding version file, and completes the delivery process of the packet.

In step 280, the normal system receives the upgrade package and writes it to the corresponding partition.

In the embodiment of the present disclosure, the short-distance wireless transmission technology solves the problem that the NB bandwidth is insufficient and the arrangement scenario is not easily reachable. For the NB module, the power consumption requirement in the integrated environment is very strict, so if the NB is in the NB The integration of the short-distance transmission chip in the module, the first thing to solve is the power consumption problem. In this system, a remote booting mechanism is introduced in the system, that is, by default, the short-distance transmission chip integrated in the NB module does not work, and is in a closed state. When the upgrade package tool device is to be upgraded, the device to be upgraded is carried. The unique identifier sends an upgrade request to the cloud. After receiving the request, the cloud sends an upgrade request to the NB module through the protocol channel between the NB module, and the NB module starts the short-distance transmission chip when receiving the upgrade request. Let it work. In this case, the upgrade package tool device and the NB module device are connected by matching through the short-distance transmission protocol to complete the transmission of the version.

In the embodiment of the present disclosure, when the device where the NB module is located is a non-dead device;

The receiving, by the NB module, the version file sent by the proximity upgrade tool device by the NB module includes: receiving, by the normal system in the NB module, the version file, and writing the version file to the backup system partition;

The NB module of step 140 performs version upgrade according to the received version file, including: after writing the version file to the backup system partition, restarting and loading the backup system;

When the device where the NB module is located is a dead device;

The version file sent by the NB module received by the NB module in the short-distance transmission module by the short-distance transmission module includes: the backup system in the NB module receives the version file, and writes the version file into a normal system partition;

The step of upgrading the NB module according to the received version file includes: after writing the version file to the normal system partition, restarting and loading the normal system.

In the embodiment of the present disclosure, in the process that the NB module receives the version file sent by the proximity upgrade tool device through the short-distance transmission module, the backup system is added to ensure the reliability of the version upgrade. That is, the upgrade software is first transferred to the backup system, and the backup system startup flag is set. If the backup system can be successfully started, the system to be upgraded is overwritten to the normal system, and then the upgrade is completed by restarting.

The following describes the specific implementation scenarios.

The following describes the version upgrade process in conjunction with the application scenario of a non-dead device.

Step 310: After each power-on, the SBL (Security Block) loads the partition of the normal system, thereby completing the loading of the normal system.

When the device is shipped from the factory, the partition started in the SBL is set to the partition of the normal system. The normal system is the working system of the user scenario. At this time, the backup system partition is not loaded, and at this time, the short-distance transmission chip does not work, and belongs to a no-power state.

In step 320, the normal system polls to check if there is an upgrade request.

Where: Polling to check if an upgrade request can be set to include three parts:

The first step is to launch the application side program and create a polling thread in it;

An application-side program is run in the system. For example, the application-side program name is update app, and the app first establishes a network connection with the cloud server and creates a polling thread therein.

The second step is to send a protocol packet to the cloud server through the thread to ask whether there is an upgrade request;

In this thread, the group coap protocol package, and the cloud server stipulates the upgrade flag, for example: UpdateNowFlag, sends the protocol packet to the cloud server, and asks whether there is an upgrade request. The cloud server responds if there is a protocol packet UpdateNowFlag set to 1, if no protocol packet UpdateNowFlag is set to 0.

The third step is to query the time interval. In order to save bandwidth and traffic, you can set it to 5 minutes. Each time the device is connected to the network, a request is sent, and the corresponding request is sent according to the corresponding time interval. After the network port, the polling thread is closed.

Step 330, in the case of upgrading, setting the short-distance transmission chip to be in an active state, and starting to send a heartbeat broadcast data packet;

After the update app in the normal system of the NB module receives the upgrade command, the short-distance transmission chip is set to work by the device node interface defined in advance, and the short-distance transmission chip is officially started. After the proximity transmission chip is started, it starts to send heartbeat broadcast data packets, for example, according to protocol types such as NFC and Zigbee. The heartbeat data is a fixed time interval data packet. For example, we can set a data packet for 1 minute. This way, the power consumption of the data packet is small, so that the short-distance transmission chip operates in a low-power operation mode.

Step 340, in the case of upgrading, the upgrade tool device initiates searching and matching;

The above startup search and matching includes:

In the first step, the upgrade tool device initiates a search function, that is, receives broadcast packet data, and parses the header data for a protocol that is used in advance to a good use.

The second step is to parse the content part of the protocol package. In order to prevent the malicious update version and ensure the security of the upgrade, the decryption operation is performed according to the encryption algorithm agreed in advance. The decryption algorithm may be the existing MD5 or other programs. Encryption and decryption algorithm.

In the third step, after the decryption is completed, the device unique identifier information is parsed.

The fourth step is to query whether the setting uniqueness identifier is in the upgrade list to be upgraded, and if not, the entire upgrade process is ended. If it is based on the address sent by the broadcast packet, a response request is sent.

The upgrade tool device can download the version file from the cloud after the matching is successful;

In another solution, the upgrade tool device may download the version file from the cloud after searching for the broadcast packet data sent by the NB module.

In the fifth step, after receiving the response request sent by the upgrade tool device, the NB module performs the decryption operation according to the encryption algorithm agreed in advance, and performs the authentication of the upgrade tool device for the parsed data, and the authentication succeeds, that is, the entire matching process is completed.

Step 350: The upgrade tool device sends the version file to the NB module; and writes the file to the backup system partition;

After the matching is successful, the upgrade tool device splits the file and the data group package according to the agreed short-distance transmission protocol, and encrypts it by using a predetermined encryption algorithm, and then sends the file to the NB module, and the NB module. The normal system receives the protocol packet data sent by the upgrade tool device and decrypts the data. Considering that the FLASH (flash memory) is the least occupied, the decrypted version file is directly written into the backup system partition according to the block mode, and then the file operation is not performed after the file is composed.

Step 360, after the transmission is completed, the normal system sets a backup system startup flag in the SBL startup item, and restarts the device;

Step 370, after the device is restarted, the backup system is loaded.

In step 380, if the loading is successful, the backup system COPY (copy) the content to the normal system, and set a normal system startup flag; after the restart, the normal system is loaded.

Step 385, if the backup system is not successfully loaded, the upgrade package has a problem, restart, and reload the normal system after the restart.

In step 390, the proximity transmission chip is turned off.

The upgrade is complete.

The following describes the version upgrade process in conjunction with the application scenario of the dead device.

Step 410: Set a SBL loading backup system when the normal system crashes;

In step 420, the backup system polls to check if there is an upgrade request.

In the first step, an application-side program is run in the system. For example, the application-side program name is update app, and the app first establishes a network connection with the cloud server and creates a polling thread therein.

Step 430, in the case of upgrading, setting the short-distance transmission chip to be in an active state, and starting to send a heartbeat broadcast data packet;

After the update app in the NB module backup system receives the upgrade command, the short-distance transmission chip is set to work by the device node interface defined in advance, and the short-distance transmission chip is officially started. After the proximity transmission chip is started, it starts to send heartbeat broadcast data packets, for example, according to protocol types such as NFC and Zigbee. The heartbeat data is a fixed time interval data packet. For example, we can set a data packet for 1 minute. This way, the power consumption of the data packet is small, so that the short-distance transmission chip operates in a low-power operation mode.

Step 440, in the case of upgrading, the upgrade tool device initiates searching and matching;

The above startup search and matching includes:

Step 450: The upgrade tool device sends the version file to the NB module; and writes the version file to the normal system partition;

After the matching is successful, the upgrade tool device splits the file and the data group package according to the agreed short-distance transmission protocol, and encrypts it by using a predetermined encryption algorithm, and then sends it to the NB module, and the NB module is normal. The system receives the protocol packet data sent by the upgrade tool device and decrypts the data. Considering that the FLASH is the least occupied, for the decrypted version file, it is directly written into the normal system partition according to the block mode, and then the file operation is not performed after the file is composed.

Step 460, after the transmission is completed, the backup system sets a normal system after starting the upgrade in the startup item, and restarts the device;

Step 470, after the device is restarted, the normal system is loaded.

In step 480, if the loading is successful, continue to run the upgraded normal system.

Step 485, if the normal system is not successfully loaded, after restarting, reload the backup system and wait for a new upgrade package request.

In step 490, the proximity transmission chip is turned off.

The upgrade is complete.

The following describes the upgrade process of another version in combination with the application scenario of the dead device.

Step 510, setting the SBL loading backup system when the normal system crashes.

In step 520, the backup system sets the proximity transmission chip to the working state by default.

Step 530, after the proximity transmission chip is started, start to send a heartbeat broadcast data packet, for example, according to a protocol type such as NFC or Zigbee. The heartbeat data is a fixed time interval packet. For example, we can set a packet for 1 minute. This way, the power consumption is very small, and it runs in a low power mode.

Step 540, in the case of upgrading, the upgrade tool device starts searching and matching;

The above startup search and matching includes:

In the fifth step, after receiving the request sent by the upgrade tool device, the NB module performs the decryption operation according to the encryption algorithm agreed in advance, and performs the authentication of the upgrade tool device for the parsed data, and the authentication succeeds, that is, the entire matching process is completed.

Step 550: The upgrade tool device sends the version file to the NB module; and writes the version file to the normal system partition;

After the matching is successful, the upgrade tool device splits the file and the data group package according to the agreed short-distance transmission protocol, and encrypts it by using a predetermined encryption algorithm, and then sends it to the NB module, and the backup system in the NB module. Receive protocol packet data sent by the upgrade tool device and decrypt the data. Considering that the FLASH is the least occupied, for the decrypted version file, it is directly written into the normal system partition according to the block mode, and then the file operation is not performed after the file is composed.

Step 560, after the transmission is completed, the backup system sets a normal system after starting the upgrade in the startup item, and restarts the device.

Step 570, after the device is restarted, the normal system is loaded.

Step 580, if the loading is successful, continue to run the upgraded normal system.

Step 585, if the normal system is not successfully loaded, after restarting, reload the backup system and wait for a new upgrade package request.

In step 590, the proximity transmission chip is turned off.

The upgrade is complete.
