Example 1
The embodiment of the invention provides an upgrading method of a cascade terminal, which can be applied to upgrading a plurality of cascade terminals, for example, the situation that all cascade cameras in a conference room are upgraded simultaneously. In the embodiment of the present invention, as shown in fig. 1, the method for upgrading a cascade terminal in the embodiment of the present invention includes the following steps:
step S1: the current terminal receives an upgrade file sent by a previous-stage terminal of the current terminal, wherein the upgrade file is used for upgrading a software version on the cascade terminal, and the current terminal is any one of the cascade terminals.
In the embodiment of the invention, the current terminal receives an upgrade file which is used for upgrading the software version on the cascade terminal, wherein the current terminal is any one of the cascade terminals, because the embodiment of the invention mainly solves the problems of high upgrade maintenance cost and inconvenient operation of the cascade terminal, the cascade terminal needing to be upgraded is at least two terminals, if the current terminal is the second terminal in the cascade terminal, the last-stage terminal of the current terminal is the first terminal in the cascade terminal, and if the current terminal is the first terminal in the cascade terminal, the last-stage terminal of the current terminal is the external upgrade terminal of the upgrade cascade terminal.
In the embodiment of the invention, a plurality of cascaded cameras in a conference room are taken as an example for explanation, the plurality of cascaded cameras are upgraded under the condition of ensuring the positions of the cameras to be still, external equipment is connected in series with any one of the cameras which are convenient to operate in a cascade terminal through a serial port line, the problem that the camera is installed too high and is inconvenient to be directly connected with the external equipment is avoided, the first camera terminal receives an upgrade file, the external equipment and a connector lug of each camera are not required to be connected in a plug-in mode, and the stability of a conference environment is ensured. It should be noted that, in the embodiment of the present invention, only the cascaded cameras are taken as an example to describe the upgrade of the cascaded terminal, in practical applications, the cascaded terminal may also be another cascaded terminal, and the external device connected in series with the cascaded terminal may also be an external terminal or a server, which is not limited to this.
Step S2: and after the current terminal receives the upgrade file, the current terminal sends the upgrade file to a next-stage terminal of the current terminal so as to enable the next-stage terminal of the current terminal to complete software version upgrade.
In the embodiment of the invention, after the current terminal receives the upgrade file, the upgrade file is directly sent to the next-stage terminal of the current terminal, so that the next-stage terminal of the current terminal finishes the software version upgrade, wherein the next-stage terminal of the current terminal is the next-stage terminal cascaded with the current terminal. The method includes that a current terminal is any one of the cascaded multiple cameras, after a first camera receives a visca instruction sent by an external upgrading device connected with the first camera through a serial port, the first camera starts an Xmodem receiving protocol of the camera, the external device starts an Xmodem sending protocol of the first camera, an upgrading file is sent to the first camera through the Xmodem protocol, and after the first camera receives the upgrading file, the upgrading file is sent to a second camera, so that the second camera finishes software version upgrading.
It should be noted that, in the embodiment of the present invention, only the cascaded cameras are taken as an example for description, and the visca instruction is also a common control instruction of the general-purpose camera, and when the cascaded terminal is other terminal equipment, the cascaded terminal may also be other corresponding control instructions, where the Xmodem serial port protocol may also be other serial port protocols, such as Xmodem _1k/Ymodem and other serial port protocols, which may be selected according to actual system requirements, and the present invention is not limited to this.
And step S3: and the current terminal receives feedback information of a next-stage terminal of the current terminal, wherein the feedback information is used for indicating that the next-stage terminal of the current terminal receives the upgrade file.
In the embodiment of the invention, after the next-stage terminal of the current terminal receives the upgrade file sent by the current terminal, the next-stage terminal of the current terminal sends a feedback message to the current terminal, wherein the feedback message is the message that the next-stage terminal of the current terminal has received the upgrade file. For example, after the second camera of the multiple cascaded cameras in the conference room receives the upgrade file sent by the first camera, the second camera sends feedback information that the upgrade file is received to the first camera, so that the first camera can be upgraded.
And step S4: and the current terminal upgrades the software version by using the upgrade file according to the feedback information.
In the embodiment of the invention, after the current terminal receives the feedback information of the next-stage terminal of the current terminal, the current terminal is upgraded by using the upgrade file. For convenience of understanding, the multiple cascaded cameras are also described as an example, after the external upgrade device and the first camera are configured, a visca instruction is sent to the first camera connected to the external upgrade device, a receiving protocol of the first camera is started, an upgrade file sent by the external device is received, then, an initialization operation of upgrading can be performed on the external device, and at the moment that the first camera is powered off and then powered on, the state of the first camera is changed into a ready state, at this moment, the first camera sends the upgrade file to a next terminal of the cascade connection, that is, to the second camera, when the second camera sends feedback information to the first camera, the first camera can be upgraded, meanwhile, the second camera sends the upgrade file to a next camera of the second camera, and so on, until all the cascaded cameras are upgraded. It should be noted that, in the embodiment of the present invention, a complete upgrade process is illustrated by cascading cameras, and this process is also applicable to other cascading terminals, and the present invention is not limited thereto.
The upgrading method of the cascade terminal provided by the invention receives the upgrading file by taking any terminal which is convenient to operate in the cascade terminal as the current terminal, sends the upgrading file to the next-stage terminal cascaded with the current terminal, and then upgrades the software version of the current terminal according to the feedback information of the next-stage terminal on the receiving condition of the upgrading file and the upgrading file. The upgrading method has the advantages that the condition that each terminal is reconnected and the mobile device is upgraded in the upgrading process of the cascade terminal is avoided, upgrading efficiency is improved, the current terminal confirms that the next-level terminal receives the upgrading file and then carries out upgrading operation, the condition that the upgrading file is changed and cannot be matched with the next-level terminal to carry out upgrading operation after the current terminal is directly upgraded is avoided, or the upgrading file is directly deleted and subsequent upgrading of other cascade terminals cannot be carried out after the current terminal is upgraded, in order to save terminal memory, the upgrading file is directly deleted, the stability of system upgrading is improved, and the cost of system maintenance is further reduced.
In a specific embodiment, as shown in fig. 2, the step of receiving, by the current terminal, the upgrade file sent by the previous terminal of the current terminal includes the following steps:
step S11: and the current terminal receives an upgrading instruction sent by a previous-stage terminal of the current terminal.
In the embodiment of the present invention, a previous terminal of a current terminal sends an upgrade instruction to the current terminal, where the previous terminal of the current terminal is a previous terminal cascaded with the current terminal, that is, assuming that there are 4 cascaded cameras in a conference room, a first camera receives an upgrade instruction and an upgrade file of an external device, the first camera sends the upgrade file to a second camera, the second camera feeds back the upgrade file to the first camera after receiving the upgrade file, and then the first camera performs an upgrade operation, and at this time, the first camera sends the upgrade instruction to the second camera. It should be noted that, in the embodiment of the present invention, a relationship between a current terminal and a terminal at a previous stage of the current terminal is described by taking 4 cascaded cameras as an example, which is not limited in practical application.
Step S12: and the current terminal starts a receiving protocol for receiving the upgrade file based on the upgrade instruction.
In the embodiment of the invention, after the current terminal receives the upgrade instruction sent by the previous terminal of the current terminal, the receiving protocol for receiving the upgrade file is started, 4 cascaded cameras are continuously arranged in a conference room, before the first camera sends the upgrade file to the second camera, the first camera sends the upgrade instruction to the second camera, so that the second camera starts the receiving protocol for receiving the upgrade file, and the first camera sends the upgrade file to the second camera.
Step S13: and the current terminal receives the upgrade file sent by the upper-level terminal of the current terminal based on the receiving protocol.
In the embodiment of the invention, after the current terminal starts the receiving protocol for receiving the upgrading file according to the received upgrading instruction, the current terminal receives the upgrading file sent by the previous-stage terminal of the current terminal according to the receiving protocol. Further, taking an example that 4 cascaded cameras are provided in the conference room as an example, the second camera is equivalent to the current terminal, the first camera of the previous terminal is equivalent to the previous terminal of the current terminal, when the first camera sends an upgrade instruction to the second camera, the second camera starts a receiving protocol, and then the second camera receives the upgrade file sent by the first camera according to the receiving protocol.
In a specific embodiment, as shown in fig. 3, in the process of version upgrade, the upgrade file is transmitted at a preset baud rate, so that influence on transmission of other files or data is avoided, or influence on transmission of other files or data is received, and thus stability of version upgrade is improved.
After the present terminal receives the upgrade order sent by the previous terminal of the present terminal, the embodiment of the present invention further includes the following steps:
step S012: the current terminal changes the baud rate of the current terminal from the default baud rate to a preset baud rate, and the preset baud rate is the baud rate for transmitting the upgrade file.
In the embodiment of the invention, the current terminal changes the baud rate of the current terminal from the default baud rate to the preset baud rate, wherein the preset baud rate is the baud rate for transmitting the upgrade file, the baud rate indicates the number of code element symbols transmitted every second, and is an index for measuring the data transmission rate, and the baud rate is represented by the frequency of carrier modulation state change in unit time. In an information transmission channel, a signal unit carrying data information is called a symbol, and the number of symbols transmitted through the channel per second is called a symbol transmission rate, which is referred to as a baud rate for short. The baud rate is an indicator of the bandwidth of the transmission channel. In practical application, the rate of a single chip or a computer during serial port communication refers to the change of a signal in unit time after being modulated, i.e., the number of times of carrier parameter change in unit time, for example, the data transmission rate is 240b/s, each character format includes 10 bits (1 start bit, 1 stop bit, 8 valid data bits), the baud rate at this time is 240baud, the baud rate can be understood as how many symbols data are transmitted (or received) by a device in one second, which is a measure of the symbol transmission rate, and 1 baud refers to 1 symbol transmitted (through different modulation modes, multiple bit information can be loaded on one symbol).
After the present terminal receives the upgrade file sent by the previous terminal of the present terminal based on the receiving protocol, the embodiment of the present invention further comprises the following steps:
step S003: the current terminal changes the baud rate of the current terminal from the preset baud rate to the default baud rate.
In the embodiment of the invention, after the current terminal sends the upgrade file, the current terminal changes the baud rate of the current terminal from the preset baud rate to the default baud rate so as to complete the upgrade operation of the current terminal without being confused with other terminals.
It should be noted that, in the embodiment of the present invention, the preset baud rate and the default baud rate are set according to the system and the practical application of the terminal, and the present invention is not limited thereto.
In a specific embodiment, as shown in fig. 4, the step of sending the upgrade file to the next-stage terminal of the current terminal by the current terminal includes the following steps:
step S21: the current terminal sends an upgrading instruction to a next-stage terminal of the current terminal, and simultaneously starts a sending protocol for sending the upgrading file, wherein the upgrading instruction is used for controlling the next-stage terminal of the current terminal to start a receiving protocol for receiving the upgrading file.
In the embodiment of the present invention, the current terminal sends an upgrade instruction to the next-stage terminal of the current terminal, the current terminal starts a sending protocol for sending an upgrade file, and the next-stage terminal of the current terminal receives the upgrade instruction and starts a receiving protocol for receiving the upgrade file.
Step S22: and the current terminal sends the upgrade file to the next-stage terminal of the current terminal based on the sending protocol.
In practical application, after the next-stage terminal of the current terminal receives the upgrade file, the next-stage terminal of the current terminal first determines whether the next-stage terminal of the current terminal is the last upgraded terminal in the cascade terminal, so as to confirm whether the upgrade file needs to be sent to the next-stage terminal or the upgrade operation needs to be directly performed.
In a specific embodiment, as shown in fig. 5, when sending the upgrade file to the next-stage terminal, it needs to first determine whether the next-stage terminal of the current terminal is the last upgraded terminal in the cascade terminal.
Step S5: and if the next-stage terminal of the current terminal is the last upgraded terminal in the cascade terminals, directly upgrading the software version by using the upgrade file.
In the embodiment of the invention, if the next-stage terminal of the current terminal is the last upgraded terminal in the cascade terminals, the next-stage terminal of the current terminal directly utilizes the upgrade file to upgrade the software version after waiting for a period of time. Taking a plurality of cascading cameras in a conference room as an example, under the condition that the next-stage terminal of the current terminal is the last upgraded terminal in the cascading terminals, the fact that two cascading cameras exist in the conference room at the moment is shown, and the external equipment is connected with the first camera through a serial port line. It should be noted that, in the embodiment of the present invention, the updating after waiting for a period of time is performed to prevent the judgment information from being incorrect until the next-stage terminal of the current terminal is determined to be the last terminal, and then the updating is performed, so that the accuracy of the updating process is ensured, which is not limited in the present invention.
Step S6: and if the next-stage terminal of the current terminal is not the last upgraded terminal in the cascade terminal, determining the next-stage terminal of the current terminal as the current terminal, and returning to execute the step that the current terminal receives the upgrade file sent by the previous-stage terminal of the current terminal.
In practical application, if the next-stage terminal of the current terminal is not the last upgraded terminal in the cascade terminal, the next-stage terminal of the current terminal is determined as the current terminal, and the upgrading work of the subsequent cascade terminal is continuously completed. Taking a plurality of cascading cameras in a conference room as an example, under the condition that a next-stage terminal of a current terminal is not the last upgraded terminal in the cascading terminals, the cascading terminals are at least three cameras at the moment, after receiving an upgrade file, a second camera sends the upgrade file to a third camera, and after receiving feedback information of the third camera, the second camera starts to upgrade the version of the camera by using the upgrade file.
In a specific embodiment, in order to ensure that all terminals in the cascade terminals are upgraded, after any one of the cascade terminals is upgraded, the upgraded message is uploaded to an external upgrade terminal step by step, the external upgrade terminal is a previous-stage terminal of a first terminal in the cascade terminals and is used for sending an upgrade file to the first terminal, and the first terminal is a terminal connected with the external upgrade terminal. For example, there are 4 cascaded cameras in a conference room, an external upgrade terminal is connected to a first camera, an upgrade file is sent to the first camera, the first camera returns a message carrying the upgrade completion of the information of the camera to the external upgrade terminal after completing the upgrade, the message carrying the upgrade completion of the information of the second camera is sent to the first camera first and then returned to the external upgrade terminal through the first camera after completing the upgrade of the second camera, and similarly, the third and fourth cameras need to transmit the message carrying the upgrade completion step by step to the upper one-level terminal until the message is sent to the external upgrade terminal. Therefore, after the external upgrading terminal receives the message of the last terminal after upgrading, the terminal which does not return the message of upgrading completion can be found, and direct connection upgrading or the upgrading operation is carried out on the terminal which does not complete upgrading according to the circumstances, so that the upgrading completion accuracy and reliability of all the cascade terminals are ensured.
In a specific embodiment, as shown in fig. 6, an upgrade file in the embodiment of the present invention is a file package formed by packaging multiple types of software version files, and a current terminal performs software version upgrade using the upgrade file according to feedback information, including the following steps:
step S41: and the current terminal decompresses the upgrade file to obtain software version files of multiple models.
In the embodiment of the invention, after the current terminal receives the feedback information of the next-stage terminal of the current terminal, the terminal upgrading operation is started by using the upgrading file, when the models of all the terminals are different, all the required versions are packaged into one upgrading file package, and each terminal obtains the files of the software versions of a plurality of models after decompressing by decompressing the upgrading file, so that the terminal can be matched with the corresponding upgrading file. It should be noted that, if all the cascading terminal models are consistent, the terminal can be upgraded by directly using an upgrade file, and the problem of mismatch does not exist.
Step S42: and the current terminal inquires corresponding software version files from the software version files of multiple models according to the model of the current terminal.
In the embodiment of the invention, when the models of the cascade terminals are different and files of software versions of a plurality of models are obtained by decompression, the current terminal inquires corresponding software version files from the files of the software versions of the plurality of models according to the model of the current terminal, wherein the current terminal can search the names of the decompressed upgrade files in a traversing manner, find the upgrade files corresponding to the model of the current terminal and then upgrade the current terminal.
In practical application, when the external device packages upgrade files of all versions and models, the upgrade files are omitted or other upgrade files are packaged incorrectly, when the current terminal performs traversal search on the name of the decompressed upgrade file, the upgrade file corresponding to the current terminal model is not found after traversal is finished, and then information of upgrade failure of the external device is returned, so that upgrade failure of the current terminal is indicated, and new upgrade files need to be packaged and sent again.
It should be noted that, the embodiment of the present invention only illustrates that traversal search is performed through file names, and in practical applications, search may also be performed through other identifiers for distinguishing upgrade files of different models, such as a special field or an ID, which is not limited by the present invention.
Step S43: and the current terminal utilizes the inquired software version file to upgrade the software version.
In the embodiment of the invention, after the current terminal obtains the upgrade file matched with the model of the current terminal, the version of the current terminal can be upgraded by using the upgrade file.
