Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Firmware determining functions and performance of the internet of things equipment is usually burned in the internet of things equipment, and the firmware in the internet of things equipment may not meet the use requirements of users over time, so that the firmware needs to be upgraded. At present, firmware upgrade in the internet of things device is usually completed according to an authorization serial number of the internet of things device, wherein the authorization serial number is issued by an authorization server providing firmware upgrade service and is stored in a nonvolatile memory or other storage media of the internet of things device. When The firmware of The internet of things equipment needs to be upgraded by OTA (Over The Air, Over The Air technology), The firmware is interacted with The authorization server through The authorization serial number, so that an OTA upgrade package for upgrading The firmware is obtained. Therefore, the authorization serial number is an important basis for upgrading the firmware of the internet of things equipment.
At present, in the process of writing the authorization serial number into the internet of things device, the authorization serial number unmatched with the device type of the device is often written into the internet of things device, and when subsequent internet of things devices are subjected to OTA upgrade, the authorization server side can push an OTA upgrade packet unmatched with the device type of the device to the internet of things device, so that the internet of things device cannot be upgraded.
In order to overcome the problem that the internet of things device is written with an authorization serial number which is not matched with the device type of the internet of things device, the embodiment of the invention provides a number writing method and a number writing system, which are specifically described below.
As shown in fig. 1, an embodiment of the present invention provides a number writing method, which mainly includes:
101. and when the number writing terminal determines that the Internet of things equipment needs to write the number, the number writing terminal acquires an authorization license certificate of the Internet of things equipment.
The number writing terminal requests an authorization serial number for the Internet of things equipment from the authorization server, and writes the requested authorization serial number into the Internet of things equipment. In order to avoid the malicious use of the number writing terminal, the number writing terminal needs to log in with a correct user name and password when in use. The user name and the password may be issued by the authorization server to the user.
After the number writing terminal is logged in, only when the fact that the Internet of things equipment needs to be written is determined, the number writing terminal requests an authorization serial number for the Internet of things equipment from the authorization server. A method for determining that the internet of things equipment needs to be numbered by a number writing terminal is described below, and the method at least includes the following two steps:
firstly, if a number writing terminal detects that the Internet of things equipment is connected to a preset interface through a serial port, it is determined that the Internet of things equipment needs to write a number.
When the internet of things equipment is connected to the preset interface through the serial port, it is indicated that the number writing requirement exists in the internet of things equipment, and it is determined that the number writing requirement exists in the internet of things equipment.
When the internet of things equipment is connected to the preset interface through the serial port, in order to ensure that the authorization serial number can be written into the internet of things equipment, the internet of things equipment needs to be normally powered on. In addition, the preset interface described herein is an interface bound by the number writing terminal, for example, it may be an interface on a computer deploying the number writing terminal.
And secondly, if the number writing terminal receives an authorized serial number writing instruction aiming at the Internet of things equipment, determining that the Internet of things equipment needs to write the number.
When the requirement of writing numbers into the Internet of things equipment exists, the Internet of things equipment or service personnel sends an authorization serial number writing instruction to a number writing terminal through a terminal which can be operated by the service personnel. And if the number writing terminal receives the authorized serial number writing instruction, determining that the Internet of things equipment needs to write the number.
The specific form of the authorized serial number writing instruction described herein may be determined based on the service requirement, and this embodiment is not particularly limited.
When the number writing terminal determines that the internet of things equipment needs to write the number, in order to avoid the fact that the internet of things equipment is written into the authorization serial number which is not matched with the equipment type of the internet of things equipment, the authorization license certificate of the internet of things equipment needs to be acquired, wherein the authorization license certificate is a certificate for the authorization server side to issue the authorization serial number for the internet of things equipment. The authorization permit is a character string with the length of M bits generated by an authorization server through an algorithm according to the manufacturer name of the Internet of things equipment and the project name of the Internet of things equipment, and the character string corresponds to the equipment type of the Internet of things equipment. Wherein the specific value of M may be determined based on the service requirement, such as 385. That is to say, the authorization license certificate is a certificate for the authorization server to issue an authorization serial number for the internet of things device of the corresponding device type.
And the number writing terminal acquires the authorization license certificate of the Internet of things equipment when determining that the Internet of things equipment needs to write the number. When the number writing terminal acquires the authorization certificate information, the authorization certificate can be acquired through a preset interaction command. Illustratively, the number writing terminal and the internet of things device agree to an interaction command, and when the number writing terminal sends the interaction command to the internet of things device, the internet of things device provides an authorization license certificate stored in the internet of things device to the number writing terminal.
102. And the number writing terminal sends a device type query request carrying the authorization license certificate to an authorization server.
In order to verify the device type corresponding to the authorization license certificate, the number writing terminal sends a device type query request carrying the authorization license certificate to the authorization server, so that the authorization server issues the device type of the authorization license certificate.
103. And the authorization server side inquires the equipment type corresponding to the authorization license certificate under the equipment type inquiry request, and sends the inquired equipment type to the number writing terminal.
The authorization server is a terminal for distributing an authorization serial number for the equipment of the internet of things, and when receiving an equipment type query request sent by a number writing terminal, the authorization server needs to analyze an authorization license carried by a serial number issuing request and then queries the equipment type corresponding to the authorization license. The foregoing parsing method is not specifically limited in this embodiment, and for example, the authorization license certificate carried in the serial number issuing request is parsed by using an HTTP GET method.
After the authorization license is distributed to the internet of things equipment, the corresponding relation between the authorization license and the equipment type exists in the authorization server, when the authorization server receives the authorization license, the equipment type corresponding to the authorization license can be directly determined according to the stored corresponding relation, and the inquired equipment type is sent to the number writing terminal.
104. And if the number writing terminal compares the equipment type issued by the authorization server with the equipment type of the Internet of things equipment, the number writing terminal requests the authorization server to issue an authorization serial number aiming at the Internet of things equipment.
And after receiving the equipment type fed back by the authorization server, the number writing terminal compares the equipment type issued by the authorization server with the equipment type of the equipment of the Internet of things. The device type of the internet of things device is the device type stored in the internet of things device, which is obtained through a serial port instruction when the number writing terminal detects that the internet of things device is connected to a preset interface through a serial port.
If the number writing terminal compares that the device type issued by the authorization server is the same as the device type of the internet of things device, it indicates that the possibility that the authorization serial number which is not matched with the device type of the internet of things device is not written in the internet of things device does not exist, and therefore the number writing terminal directly requests the authorization server to issue the authorization serial number aiming at the internet of things device. The authorization serial number is a basis for acquiring an OTA upgrade package when the IOT equipment carries out OTA upgrade.
If the type of the equipment issued by the authorization server is different from the type of the equipment of the internet of things equipment by comparison, the number writing terminal indicates that the possibility that the authorization serial number which is not matched with the type of the equipment of the internet of things equipment is written into the equipment of the internet of things equipment exists, so that a prompt of replacing the authorization license certificate needs to be sent out, and the number writing terminal uses the authorization license certificate which is matched with the type of the equipment of the internet of things equipment to request the authorization serial number for the internet of things equipment.
According to the number writing method provided by the embodiment of the invention, when the number writing terminal determines that the Internet of things equipment needs to write the number, the number writing terminal acquires the authorization license certificate of the Internet of things equipment and sends an equipment type query request carrying the authorization license certificate to the authorization server side. And the authorization server side inquires the equipment type corresponding to the authorization license certificate under the equipment type inquiry request, and sends the inquired equipment type to the number writing terminal. And if the number writing terminal compares that the equipment type issued by the authorization server is the same as the equipment type of the equipment in the Internet of things, the number writing terminal requests the authorization server to issue an authorization serial number aiming at the equipment in the Internet of things. Therefore, according to the scheme provided by the embodiment of the invention, only when the number writing terminal compares the device type issued by the authorization server and the device type of the internet of things device, the authorization server is requested to issue the authorization serial number aiming at the internet of things device, so that the phenomenon that the internet of things device is written into the authorization serial number which is not matched with the device type of the internet of things device can be avoided.
Further, according to the method shown in fig. 1, another embodiment of the present invention further provides a number writing method, as shown in fig. 2, the method mainly includes:
201. and when the number writing terminal determines that the Internet of things equipment needs to write the number, the number writing terminal acquires an authorization license certificate of the Internet of things equipment.
The authorization license certificate is a certificate for the authorization server side to issue an authorization serial number for the equipment of the internet of things. One authorization license certificate corresponds to one device type, and is a certificate for an authorization server to issue an authorization serial number for the internet of things device of the corresponding device type.
202. And the number writing terminal sends a device type query request carrying the authorization license certificate to an authorization server.
203. The authorization server side judges whether the authorization license certificate still has the name of the issued authorization serial number under the device type query request, if not, the step 204 is executed; if so, go to step 205.
The authorization license certificate is a certificate of issuing an authorization serial number for the internet of things equipment with a preset name by the authorization server, and the number of the name under the authorization license certificate is reduced by one after the authorization serial number is issued to one internet of things equipment by the authorization server.
Since the corresponding quota of each authorized license certificate is limited, after receiving the authorized license certificate, the authorization server needs to determine whether the authorized license certificate has the quota of issuing the authorized serial number.
204. And if the authorization server side determines that the authorization license certificate does not have the name of the issued authorization serial number, exception handling is carried out, and the current process is ended.
If the authorization server determines that the authorization license does not have the name of the issued authorization serial number, the name of the authorization license is used up, the authorization license cannot be used any more to generate the authorization serial number for the equipment of the internet of things, and exception handling is required.
The exception handling process described above may exist in two types:
firstly, if the authorization server determines that the authorization license does not have the name of issuing the authorization serial number, the authorization server notifies the number writing terminal to replace the authorization license of the internet of things equipment.
When the authorization server determines that the authorization license does not exist and issues the name of the authorization serial number, the name of the authorization license is used up, the authorization license cannot be used any more to generate a corresponding authorization sequence code for the equipment of the internet of things, and the number writing terminal needs to be notified to update the authorization license of the equipment of the internet of things. The notification may be in the form of a presentation prompt on a graphical interface.
Secondly, if the authorization server determines that the authorization license does not have the name of issuing the authorization serial number, a new authorization license is distributed to the Internet of things equipment, and the new authorization license is issued to the number writing terminal.
When the authorization server determines that the authorization license does not have the name of the issued authorization serial number, the name of the authorization license is used up, the authorization license cannot be used any more to generate a corresponding authorization serial number for the equipment of the internet of things, a new authorization license is distributed to the equipment of the internet of things, and the new authorization license is issued to the number writing terminal, so that the number writing terminal uses the new authorization license to request the authorization serial number for the equipment of the internet of things.
Here, the method for allocating a new authorization certificate to the internet of things device may be: and generating a new character string with the length of M bits through an algorithm according to the manufacturer name of the Internet of things equipment and the project name of the Internet of things equipment.
205. And if the authorization server determines that the authorization license still has the name of issuing the authorization serial number, inquiring the equipment type corresponding to the authorization license, and issuing the inquired equipment type to the number writing terminal.
In order to avoid that the internet of things equipment is written into the authorization serial number which is not matched with the equipment type of the internet of things equipment, the authorization server side feeds back the equipment type corresponding to the authorization license certificate to the number writing terminal when determining that the authorization license certificate also has the name of issuing the authorization serial number.
206. The number writing terminal compares the equipment type issued by the authorization server with the equipment type of the equipment of the Internet of things, and if the equipment type issued by the authorization server is the same as the equipment type of the equipment of the Internet of things, step 207 is executed; and if the equipment type issued by the authorization server is different from the equipment type of the equipment of the internet of things, executing step 208.
207. And if the number writing terminal compares that the equipment type issued by the authorization server is the same as the equipment type of the Internet of things equipment, the number writing terminal requests the authorization server to issue an authorization serial number aiming at the Internet of things equipment, and the current process is ended.
If the number writing terminal compares that the device type issued by the authorization server is different from the device type of the internet of things device, it indicates that the possibility that the authorization serial number which is not matched with the device type of the internet of things device is not written in the internet of things device does not exist, and therefore the authorization server is directly requested to issue the authorization serial number aiming at the internet of things device.
The specific process of requesting the authorization server to issue the authorization serial number aiming at the Internet of things equipment comprises the following steps: the number writing terminal acquires the equipment information of the Internet of things equipment and sends a serial number issuing request carrying the equipment information to the authorization server so that the authorization server issues an authorization serial number generated based on the equipment information.
The authorization serial number is a basis for acquiring an OTA upgrade package when the IOT equipment carries out OTA upgrade. The physical network equipment can upgrade the internal firmware after acquiring the OTA upgrade package.
208. And if the number writing terminal compares that the equipment type issued by the authorization server is different from the equipment type of the equipment of the Internet of things, sending a prompt for replacing the authorization license certificate.
If the type of the equipment issued by the authorization server is different from the type of the equipment of the internet of things equipment by comparison, the number writing terminal indicates that the possibility that the authorization serial number which is not matched with the type of the equipment of the internet of things equipment is written into the equipment of the internet of things equipment exists, so that a prompt of replacing the authorization license certificate needs to be sent out, and the number writing terminal uses the authorization license certificate which is matched with the type of the equipment of the internet of things equipment to request the authorization serial number for the internet of things equipment.
Further, according to the above method embodiment, another embodiment of the present invention further provides a number writing system, as shown in fig. 3, where the number writing system includes:
