Hereinafter, the contents of the claims of the present invention are explained by specific exemplary embodiments so that those skilled in the art can better understand the scope of the claims of the present invention. It is to be understood that the following exemplary embodiments are not intended to limit the scope of the present invention, but are merely illustrative of the present invention.
Exemplarily, referring to fig. 2, in an embodiment of the transmission method of upgrade data of the present invention, the transmission method of upgrade data includes the following steps:
step S1, receiving a first data frame sent by a first device; the first data frame comprises upgrading data;
in this embodiment, the main body executing the transmission method of the upgrade data is a transparent transmission device.
The transparent transmission equipment can establish communication connection with first equipment on an upper layer and receive data sent by the first equipment, and the first equipment mainly processes related upgrading data of equipment to be upgraded received from other places to obtain a first data frame and then sends the first data frame to the transparent transmission equipment.
It can be understood that, a case that the first device sends the first data frame to the transparent transmission device is generally that the second communication protocol of the first device is not matched with the first communication protocol of the device to be upgraded, and the first data frame is sent to the transparent transmission device for conversion processing when the device to be upgraded cannot process the first data frame due to the fact that the first data frame is directly sent to the device to be upgraded. It is worth noting that in an actual application scenario, the types of the devices to be upgraded are various, and the first device is difficult to directly communicate with the devices to be upgraded of different device types (because of differences in communication protocols), so that the application takes the transparent transmission device as a hub station, and intensively transmits the upgrading programs of different first devices to send different devices to be upgraded, so as to greatly improve the communication compatibility among different devices, and make the application scenario thereof wider.
Optionally, before executing 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 to instruct the first device to transmit the first data frame.
When first data frames need to be sent to the transparent transmission equipment, the first equipment sends a starting data frame to the transparent transmission equipment firstly, the starting data frame is used for informing the transparent transmission equipment to enter a transparent transmission mode and receiving the first data frame, the starting data frame at least comprises a transparent transmission zone bit, and the transparent transmission zone bit is used for the transparent transmission equipment to enter the transparent transmission mode according to the transparent transmission zone bit, besides, the starting data frame also comprises: the transparent transmission port number, the communication address of the equipment, the link, the protocol, the baud rate and other information or a combination of a plurality of information. The transparent transmission mode refers to entering a preset processing logic, and the processing logic refers to steps S1 and steps 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 essence of the response data frame is feedback information, and may be to notify the first device that the data frame that needs to be converted may be sent, or to notify the first device that the data frame is sent incorrectly, where the sending comprises a start data frame error or a device error of the first device. And after receiving the response data frame, the first equipment analyzes the content of the response data frame. And if the first equipment knows that the transparent transmission equipment enters the transparent transmission mode according to the response data frame, the first equipment sends the first data frame to the transparent transmission equipment. And if the first equipment knows that the starting data frame is wrong according to the response data frame, the first equipment adjusts the starting data frame and retransmits the adjusted starting data frame to the first equipment. And if the first equipment knows the error of the transparent transmission equipment according to the response data frame, sending feedback information of the error of the transparent transmission equipment to the upper-layer equipment, or prompting the user of the error of the transparent transmission equipment through a display page of the first equipment.
Step S2, converting the format of the first data frame according to a first communication protocol corresponding to the 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 common language, and in this embodiment, the communication protocol includes a first communication protocol of the device to be upgraded, a second communication protocol of the first device, and a third communication protocol of other devices. The device to be upgraded has its own first communication protocol, the transparent transmission device converts the first data frame according to the first communication protocol, and the mode for the transparent transmission device to acquire the first communication protocol may be: the first data frame is analyzed, and a first communication protocol is acquired according to the information about the equipment to be upgraded in the first data frame, so that the real-time performance is achieved; or the first device sends other data frames, such as a starting data frame, so as to send the first communication protocol to the transparent transmission device, and the accuracy is high; or the first communication protocol of the device to be upgraded is pre-stored in the storage medium of the transparent transmission device, the identification field of the communication protocol is acquired in the data frame sent by the first device, 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 a second data frame corresponding to the first communication protocol. The device to be upgraded can process the data frame on the premise that the data frame conforms to 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 can be understood that data interaction between two devices with different communication protocols cannot be normally performed. If the communication protocols between the first device and the device to be upgraded are different, an intermediate device is needed to perform data conversion on the related data, so that the first device and the device to be upgraded can interact normally. The method for converting the first data frame by the transparent transmission equipment can be divided into two cases, wherein the first case is that the first equipment packs the transmission of the upgrade data into the first data frame based on the second communication protocol of the first equipment and sends the first data frame to the transparent transmission equipment; and the second is that other devices pack the transmission of the upgrade data into a first data frame based on a second communication protocol of the other devices, send the first data frame to the first device, and forward the first data frame to the transparent transmission device by the first device.
Optionally, if the first condition is met, 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; and replacing the field value of the encapsulation field based on the first communication protocol, wherein the first data frame after the field value replacement is taken as a second data frame. The first device can pack a protocol identifier of a second communication protocol of the first device into an encapsulation field of the first data frame when packing the first data frame, the transparent transmission device can obtain the second communication protocol of the first device by analyzing the first data frame, the first device can also send the second communication protocol or the protocol identifier to the transparent transmission device by 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 calls the second communication protocol when confirming the identifier of the second communication protocol, and similarly, the first communication protocol of the device to be upgraded can be obtained by analyzing the first data frame or other data frames, or extracts the protocol identifier related to the first communication protocol in the first data frame or other data frames, and calls the first communication protocol stored in the transparent transmission device.
Optionally, if it is the second case, the transparent transmission device cannot convert the data frame according to the second communication protocol, but the upgrade data is transmitted as the first data frame, and the encapsulation fields are generally located at the front and the rear of the first data frame, the encapsulation fields at the front and the rear of the first data frame are deleted, and the data frame is re-encapsulated 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 the rear of the first data frame can also be directly used in the first situation, and in addition, the third communication protocol of other devices can also be confirmed, the data frame can have a protocol identifier, the corresponding third communication protocol is called and prestored according to the protocol identifier, and all the encapsulation fields of the first data frame are determined according to the third communication protocol; and replacing the field value of the encapsulation field of the data frame based on the first communication protocol, and taking the first data frame after the encapsulation field replacement as a second data frame. Similarly, the third communication protocol may be obtained by analyzing the first data frame or pre-storing the third communication protocol and extracting the protocol identifier.
Step S4, sending the second data frame to the device to be upgraded, where the second data frame is used to upgrade the device 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. And the equipment to be upgraded is hardware equipment, and the software data running on the hardware equipment needs to be frequently upgraded in the stages of client new requirement import, process software upgrade, self-optimization iteration, software bug solving, new industry entering and process accumulation.
It can be understood that, because the types of products related to the device to be upgraded are numerous, for terminal devices such as HMI and mobile phone, or other devices having a function of receiving upgrade data, the first communication protocols of different devices to be upgraded cannot be matched one by one, that is, communication cannot be realized, so that the transmission method of upgrade data provided by this embodiment is applied to transparent transmission devices, can be adapted to different devices to be upgraded and superior devices (terminal devices such as mobile phone, or other devices having a function of receiving and sending upgrade data), plays a role in starting and stopping, and further realizes forwarding of upgrade data, so that software upgrade can be performed on different devices to be upgraded through different devices.
In the technical scheme disclosed in this embodiment, the transmission method of the upgrade data is applied to the transparent transmission device, and receives a first data frame sent by a first device; the first data frame comprises upgrading data; carrying out 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. Therefore, 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 the upgrading program based on the second data frame and realize software upgrading, and the equipment to be upgraded can be adapted to different types of equipment to be upgraded. Meanwhile, the software upgrading is realized by transmitting the upgrading data through communication connection, and technicians do not need to burn on site, so that the effect of improving the efficiency of software upgrading of the equipment is achieved.
Optionally, referring to fig. 3, based on any one of the above embodiments, in another embodiment of the upgrade data transmission method of the present invention, the upgrade data transmission method includes:
step S10, receiving parameter information input by a user; the parameter information comprises a communication protocol identification; the communication protocol identification is used for identifying a first communication protocol adopted by the equipment to be upgraded;
in this embodiment, the main body that performs the transmission method of the upgrade data is the first device.
The equipment to be upgraded is hardware equipment with simple communication, generally cannot be accessed to a network, and can establish communication connection with the first equipment through the transparent transmission equipment. The first device is connected to a higher-level device (a terminal device such as a mobile phone and a server, or other devices capable of receiving upgrade data), and the first device may be an HMI device (human-machine interface device), an IOT device (internet of things device), or the like. The first device and the superior device may be in wireless connection (such as WIFI, bluetooth, ZigBee, etc.) or in wired connection. The upper level device can access a PLM (product lifecycle management system) which stores an upgrade program. The superior device or the first device has a user interaction page, the superior 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 is called according to the upgrading task, and the first device can forward an upgrading file to another first device or transparent transmission equipment. 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 an upgrade file sent by the superior device, that is, the current upgrade task is determined, the parameter information and the upgrade data input by the corresponding user in the upgrade file need to be determined, the parameter information at least includes 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 can also be provided with a user interaction interface for directly receiving the parameter information input by the user, the parameter information at least comprises a communication protocol identifier, and after the parameter information is confirmed, the first device is connected with the superior device to obtain the upgrading 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, sending 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 transmission device, where the transparent transmission device is used to convert the data frame, and finally, the first device may send the data frame carrying the upgrade program to the device to be upgraded. The key of whether the first device sends 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 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 starting data frame carrying parameter information is sent to a transparent transmission device, the starting 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 upgrading data to the equipment to be upgraded based on the second communication protocol. Furthermore, the first device can package the upgrade data into a 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;
