The slave module can be a GPRS module, an NB-IoT module and other wide area network wireless modules, can be directly accessed to a telecommunication operator base station and is finally accessed to the Internet, and the Internet of things control equipment is certain equipment in the Internet; the slave module can also be a ZigBee module, a Wifi module and other local area network wireless modules, the internet of things control device is connected with the internet of things terminal device through the slave module 1 in a downlink mode, the internet of things control device can be connected with the internet of things terminal device in an uplink mode through a GPRS module, an NB-IoT module or a wired mode and the like, and the internet of things control device is controlled by one device in the internet.
Based on the above module introduction, a flowchart of the remote upgrade method is shown in fig. 2, and includes:
and S11, generating and storing the firmware upgrade package.
And S12, enabling the main module in the terminal device to inquire whether the firmware upgrade package exists in the control device.
And S13, receiving query information of a main module in the terminal equipment, and sending the firmware upgrade package to the terminal equipment according to a download request sent by the main module.
And S14, if the firmware upgrade package exists, erasing the file in the upgrade package downloading area in the terminal equipment, sending a downloading request to the control equipment, and downloading the firmware upgrade package to the erased upgrade package downloading area.
And S15, enabling the main module to verify the downloaded firmware upgrade package, and sending the verification result to the control equipment.
And S16, receiving the verification result sent by the terminal equipment.
And S17, when the verification is successful, sending an activation instruction including the integrity verification value of the firmware upgrade package to the terminal equipment, and receiving an activation result replied by the terminal equipment.
And S18, when the verification is successful, receiving an activation instruction including a firmware upgrade package integrity verification value sent by the control equipment, and activating an upgrade program based on the downloaded firmware upgrade package.
In implementation, the main step of the remote upgrade method is to generate a firmware upgrade package including an adapter module identification number, a firmware version number, a firmware size, and firmware integrity check information (such as a HASH value, CRC32, etc.) at the control device. Then, the main module in the terminal device is caused to send an inquiry request as to whether or not to generate the firmware upgrade package to the control module.
And at the moment, if the firmware upgrading packet exists in the control equipment, the firmware upgrading packet is sent to the main module in the terminal equipment. After receiving the firmware upgrade package, the main module firstly checks the integrity of the firmware upgrade package for the first time and sends a check result to the control equipment.
If the verification result shows that the firmware upgrading packet is complete, the control equipment is made to send an activation instruction to the main module, so that the main module can perform an upgrading process based on the firmware upgrading packet after receiving the activation instruction; and if the verification result shows that the firmware upgrading packet is incomplete, the control equipment deletes the stored firmware upgrading packet.
It should be noted that even if the verification result indicates that the firmware upgrade package is complete, the control device may select whether to perform the subsequent activation operation according to the actual situation, and the fact that the firmware upgrade package is complete does not mean that the subsequent activation operation must be performed.
In step S12, in addition to causing the main module to send an inquiry request to the control device to obtain the firmware upgrade package, the control device may further cause the control device to push information that the firmware upgrade package has been generated to the terminal device after generating the firmware upgrade package, and cause the main module to inquire whether the upgrade package is adapted to a certain module.

s153, if the comparison results are consistent, the verification is successful;
and S154, if the comparison results are different, indicating that the verification fails.
In practice, the integrity check used herein corresponds to a hash algorithm, sometimes also referred to as a hash in terms of transliteration. The hashing algorithm can transform data of an arbitrary size (raw data) into small data of a fixed size.
Hash algorithms are often used as integrity checks for files because of their irreversibility and resultant uniqueness.
Optionally, the step of activating the upgrade proposed by S18 includes:
s181, comparing the integrity check value in the activation instruction with the integrity check value obtained by calculation;
and S182, enabling the firmware upgrading package to upgrade the firmware under the condition that the comparison result is consistent.
In implementation, the firmware upgrading operation can be performed after an activation instruction sent by the control device is received. Before the firmware upgrade operation, the integrity check value in the activation command needs to be extracted and compared with the integrity check value calculated in step S15, that is, the integrity check of the firmware upgrade package needs to be performed again to ensure that the firmware upgrade operation can be performed correctly.
