The following is a description of what is claimed in the claims of the present invention by means of specific exemplary embodiments, so that those skilled in the art can better understand the scope of the claims of the present invention. It should be understood that the following exemplary embodiments do not limit the scope of the present invention, but are only used to illustrate the present invention.
Illustratively, referring to fig. 2, in an embodiment of the method for transmitting upgrade data of the present invention, the method for transmitting upgrade data comprises the steps of:
Step S1, a first data frame sent by first equipment is received; the first data frame comprises upgrade data;
In this embodiment, the main body that performs the transmission method of the upgrade data is a pass-through device.
The transparent transmission equipment can establish communication connection with the first equipment of the upper layer, receives data sent by the first equipment, and the first equipment mainly processes relevant upgrading data of equipment to be upgraded received from other places to obtain a first data frame and sends the first data frame to the transparent transmission equipment.
It can be understood that, in the case that the first device sends the first data frame to the transparent device, the second communication protocol of the first device is generally not matched with the first communication protocol of the device to be upgraded, and when the first data frame is directly sent to the device to be upgraded, the first data frame is sent to the transparent device for conversion processing when the device to be upgraded cannot process the first data frame. It is worth noting that in the practical application scene, the equipment types of the equipment to be upgraded are various, and the first equipment is difficult to directly communicate with the equipment to be upgraded of different equipment types (because of the difference of communication protocols), so that the application uses the transparent equipment as a hub station to intensively forward the upgrade programs of the different equipment to be upgraded sent by the different first equipment, so that the communication compatibility among the different equipment is greatly improved, and the application scene is wider.
Optionally, before performing step S1, the method further includes the following steps: receiving a starting data frame sent by the first equipment, wherein the starting data frame comprises a transparent transmission zone bit; entering a transparent transmission mode after receiving the transparent transmission flag bit; returning a response data frame to the first device; the response data frame is used for indicating the first device to send the first data frame.
When the first device needs to send the first data frame to the transparent device, the first device will send a start data frame to the transparent device first for notifying the transparent device to enter the transparent mode, and receive the first data frame, where the start data frame includes at least a transparent flag bit, and the transparent flag bit is used for the transparent device to enter the transparent mode according to the transparent flag bit, and in addition, the start data frame may further include: a combination of one or more of the information of the transparent port number, the device communication address, the link, the protocol, and the baud rate. The transparent transmission mode refers to entering into preset processing logic, and the processing logic refers to step S1 and steps subsequent to step S1.
Optionally, after the transparent transmission device enters the transparent transmission mode, a response data frame may be sent to the first device, where the nature of the response data frame is feedback information, which may be notifying the first device that the data frame to be converted may be sent, or may be notifying the first device that an error is sent, including a start data frame error or an own device error, or the like. After receiving the response data frame, the first device parses out the content of the response data frame. And if the first device knows that the transparent transmission device has entered the transparent transmission mode according to the response data frame, sending the first data frame to the transparent transmission device. If the first device knows the startup data frame error from the response data frame, the first device adjusts the startup data frame and resends the adjusted startup data frame to the first device. If the first device knows the transparent equipment error according to the response data frame, the feedback information of the transparent equipment error is sent to the upper layer device, or the user is prompted to the transparent equipment error through the display page of the first device.
Step S2, performing format conversion on the first data frame according to a first communication protocol corresponding to equipment to be upgraded to obtain a second data frame corresponding to the first communication protocol;
In this embodiment, the communication protocol provides communication support for the internet connecting different operating systems and different hardware architectures, and is a network general-purpose language, and in this embodiment, the communication protocol includes a first communication protocol of a device to be upgraded and a second communication protocol of the first device, and a third communication protocol of other devices. The device to be upgraded has a first communication protocol of the device itself, and the transparent transmission device converts the first data frame according to the first communication protocol, and the transparent transmission device may acquire the first communication protocol by: analyzing the first data frame, and acquiring a first communication protocol according to information about equipment to be upgraded in the first data frame, so that the real-time performance is realized; or the first device sends other data frames, such as a start data frame, so as to send the first communication protocol to the transparent transmission device, so that accuracy is achieved; or the first communication protocol of the equipment to be upgraded is prestored in a storage medium of the transparent transmission equipment, an identification field of the communication protocol is obtained in a data frame sent by the first equipment, and the required communication protocol is called, so that the efficiency is high.
In this embodiment, the transparent transmission device performs format conversion on the first data frame according to the first communication protocol for the device to be upgraded, and converts the first data frame into the second data frame corresponding to the first communication protocol. The premise that the device to be upgraded can process the data frame is that the data frame accords with a first communication protocol of the device to be upgraded, so that the transparent transmission device needs to package the first data frame according to the first communication protocol so as to convert the first data frame into a second data frame corresponding to the first communication protocol.
It will be appreciated that data interaction between two devices having different communication protocols is not normally possible. If the communication protocols between the first device and the device to be upgraded are different, an intermediate device is required to perform data conversion on the related data, so that the interaction between the first device and the device to be upgraded can be performed normally. The first data frame converted by the transparent transmission device can be divided into two cases, wherein the first case is that the first device packages the transmission of the upgrade data into the first data frame based on the second communication protocol of the first device and sends the first data frame to the transparent transmission device; the second is that the other devices package the transmission of the upgrade data into a first data frame based on the own second communication protocol, the first data frame is sent to the first device, and then the first device forwards the first data frame to the transparent transmission device, and in the second case, the first data frame may or may not match with the second communication protocol of the first device.
Optionally, if the first case is the first case, the transparent transmission device determines an encapsulation field of the first data frame according to a second communication protocol corresponding to the first device; acquiring a first communication protocol corresponding to the equipment to be upgraded; and replacing the encapsulation field based on the first communication protocol to obtain a second data frame corresponding to the first communication protocol. The transparent transmission equipment can confirm a second communication protocol corresponding to the first equipment; determining an encapsulation field of the first data frame according to the second communication protocol; the first data frame after the field value replacement is taken as a second data frame based on the field value of the first communication protocol replacement encapsulation field. The first device may package the protocol identifier of the second communication protocol of the first device into the package field of the first data frame when packaging the first data frame, the transparent transmission device may obtain the second communication protocol of the first device by parsing the first data frame, the first device may also send the second communication protocol or the protocol identifier to the transparent transmission device by using other data frames, for example, starting the data frame, the transparent transmission device stores the second communication protocol of the first device in a storage medium of the transparent transmission device in advance, and when confirming the identifier of the second communication protocol, the second communication protocol is invoked, and likewise, the first communication protocol of the device to be upgraded may be obtained by parsing the first data frame or other data frames, or extracting the protocol identifier related to the first communication protocol in the first data frame or other data frames, and invoking the first communication protocol pre-stored in the transparent transmission device.
Optionally, if the second situation is the above, the transparent transmission device cannot convert the data frame according to the second communication protocol, but the transmission of the upgrade data into the first data frame generally adopts encapsulation, and the encapsulation fields are generally located at the front and rear of the first data frame, deleting the encapsulation fields at the front and rear of the first data frame, and repackaging the data frame according to the set first communication protocol with the device to be upgraded. It can be understood that deleting the encapsulation fields at the front and rear of the first data frame may also be directly used in the first case, or may further confirm a third communication protocol of other devices, where the data frame may have a protocol identifier, call a pre-stored corresponding third communication protocol according to the protocol identifier, and determine all the encapsulation fields of the first data frame according to the third communication protocol; and replacing the first data frame after the encapsulated field replacement as a second data frame based on the field value of the encapsulated field of the first communication protocol. Similarly, the third communication protocol may be acquired by analyzing the first data frame or pre-storing the third communication protocol and extracting the protocol identifier.
And S4, sending the second data frame to the equipment to be upgraded, wherein the second data frame is used for upgrading the equipment to be upgraded.
In this embodiment, a communication connection is established between the transparent transmission device and the device to be upgraded, and the transparent transmission device may send the second data frame to the device to be upgraded based on the communication connection. The equipment to be upgraded receives the second data frame, analyzes the upgrading data in the second data frame, performs upgrading operation on relevant software according to the upgrading data, and is hardware equipment, wherein the software data running on the hardware equipment needs to be frequently upgraded in the new requirement importing of clients, the process software upgrading, the self-optimizing iteration, the software bug solving, the new industry and the process accumulation stage.
It can be understood that, because the product types related to the equipment to be upgraded are numerous, for terminal equipment such as HMI, mobile phones and other equipment with function of receiving upgrade data, the first communication protocol of different equipment to be upgraded cannot be matched one by one, that is, communication cannot be realized, so that the transmission method of the upgrade data provided by the embodiment is applied to the transparent equipment, and can be adapted to different equipment to be upgraded and superior equipment (terminal equipment such as mobile phones and other equipment with function of receiving and transmitting upgrade data), thereby playing a role of up-down, and further realizing forwarding of the upgrade data, so that software upgrade can be performed on different equipment to be upgraded through different equipment.
In the technical scheme disclosed in the embodiment, the transmission method of the upgrade data is applied to the transparent transmission equipment and receives the first data frame sent by the first equipment; the first data frame comprises upgrade data; performing format conversion on the first data frame according to a first communication protocol corresponding to equipment to be upgraded to obtain a second data frame corresponding to the first communication protocol; and sending the second data frame to the equipment to be upgraded, wherein the second data frame is used for upgrading the equipment to be upgraded. In this way, the first data frame which does not meet the first communication protocol is converted into the second data frame which meets the first communication protocol of the equipment to be upgraded, so that the equipment to be upgraded can determine an upgrading program and realize software upgrading based on the second data frame, and different types of equipment to be upgraded can be adapted. Meanwhile, the software upgrading is realized by transmitting upgrading data through communication connection, and a technician is not required to go to the site for burning, so that the effect of improving the efficiency of upgrading the software of the equipment is achieved.
Optionally, referring to fig. 3, based on any one of the foregoing embodiments, in another embodiment of the method for transmitting upgrade data of the present invention, the method for transmitting upgrade data includes:
step S10, receiving parameter information input by a user; the parameter information comprises a communication protocol identifier; the communication protocol identifier is used for identifying a first communication protocol adopted by equipment to be upgraded;
In this embodiment, the main body that performs the transmission method of the upgrade data is the first device.
The device to be upgraded is a hardware device with simple communication, generally cannot access a network, and can establish communication connection with the first device through the transparent transmission device. The first device is connected with a superior device (a terminal device such as a mobile phone, a server, or other devices with upgrade data receiving function), and the first device may be an HMI device (a man-machine interface device), an IOT device (an internet of things device), or the like. The first device and the upper device may be a wireless connection (such as WIFI, bluetooth, zigBee, etc.) or a wired connection. The superior device can access a PLM (product lifecycle management system) that stores an upgrade program. The upper-level device or the first device is provided with a user interaction page, the upper-level device or the first device receives parameter information input by a user through the user interaction page, the parameter information can determine a current upgrading task, upgrading data are called according to the upgrading task, and the first device can forward an upgrading file to the other first device or the transparent transmission device. The upgrade file includes parameter information (which may include the type of device to be upgraded, station number, port number, communication link, communication protocol, communication baud rate, etc.) and upgrade data.
When the first device receives the upgrade file sent by the superior device, the current upgrade task is determined, and the parameter information and the upgrade data input by the corresponding user in the upgrade file need to be confirmed, wherein the parameter information at least comprises a first communication protocol identifier of the device to be upgraded, and the upgrade data and the parameter information can be determined from the upgrade file sent by the superior device. The first device may also be provided with a user interaction interface, and directly receive parameter information input by a user, where the parameter information at least includes a communication protocol identifier, and after the first device confirms the parameter information, the first device connects to a superior device, and obtains an upgrade program from the superior device.
Step S20, if the second communication protocol adopted by the first equipment is different from the first communication protocol adopted by the equipment to be upgraded, transmitting a starting data frame carrying the parameter information to the transparent transmission equipment;
In this embodiment, the first device may directly send the first data frame carrying the upgrade program to the device to be upgraded or the transparent device, where the transparent device is used to convert the data frame, and finally, send the data frame carrying the upgrade program to the device to be upgraded. The key of the first device sending to the device to be upgraded or the transparent transmission device is whether the second communication protocol adopted by the first device is the same as the first communication protocol adopted by the device to be upgraded by 2.
The method comprises the steps that a first device obtains a first communication protocol of the first device and a second communication protocol of a device to be upgraded, if the second communication protocol adopted by the first device is different from the first communication protocol adopted by the device to be upgraded, a start data frame carrying parameter information is sent to a transparent transmission device, the start data frame further comprises a transparent transmission flag bit, and the transparent transmission device is informed of entering a transparent transmission mode.
Optionally, if the second communication protocol adopted by the first device is the same as the first communication protocol adopted by the device to be upgraded, receiving upgrade data sent by the superior device; and sending the upgrade data to the equipment to be upgraded based on the second communication protocol. Furthermore, the first device can encapsulate the upgrade data into the first data frame based on the second communication protocol, and directly send the first data frame to the device to be upgraded.
Step S30, receiving a response data frame returned by the transparent transmission equipment according to the starting data frame;
In this embodiment, when receiving a transmission flag bit of a start data frame sent by a first device, after entering a transmission mode, a response data frame is returned to the first device, where the response data frame is used to instruct the first device to send the first data frame, and after the first device receives the response data frame returned by the transmission device according to the start data frame and determines that the transmission device enters the transmission mode.
