With the enrichment of financial robot functions, financial robots have a large number of component modules. According to the built-in applications, the component modules cooperate with each other to complete financial work. In the current usage scenario, there is a need to upgrade the applications of each component module. Since the application of the component module is burned into the new product and then soldered to the printed circuit board, a special socket is required when upgrading the application of the component module. The maintenance personnel need to insert the upgrade device into the interface for upgrading. The upgrade efficiency is not high and errors may be encountered during the upgrade process.

[0042] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0045] See also Figure 1 , is a network architecture diagram provided in an embodiment of the present application. The network architecture of the present application includes: a remote host 10 and a financial robot 11. The financial robot 11 includes multiple component modules. The number of terminal devices is not limited in the present application. For example: Figure 1The multiple component modules in are: component module 1, component module 2, ..., component module N, where N is an integer greater than 1. The component modules implement different functions in the financial robot, such as: scanning function, printing function, image processing function, authentication function, etc. Each component module is provided with a processor, so it has the ability to communicate with the remote host 10 independently, and at the same time, each component module can communicate with each other based on the modbus bus. The component module and the remote host 10 can communicate with each other using a serial-based network communication protocol, such as the modbus protocol. Each component module can be provided with a separate memory, that is, each component module has a separate storage space, or each component module can share a memory, in which storage space is allocated to each component module. Optionally, the storage space of each component module can be divided into a first storage space and a second storage space.

[0046] based on Figure 1 For network architecture, see Figure 2 , is a flow chart of a method for upgrading a financial robot component module provided in an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps:

[0047] S201, receiving an upgrade request from a remote host.

[0048] Among them, the remote host will query the version number of the application on each component module in the financial robot. When the version number of the component module is inconsistent with the version number of the component module on the remote host, an upgrade request will be sent to the component module, and the upgrade request will carry the identification of the target component module to be upgraded. For example: the target component module is component module 1, the version number of the current application on component module 1 is V1.0, and the version number of the application of component module 1 stored on the remote host is V1.1. Then, when the two are different, the remote host will send an upgrade request to component module 1, and the upgrade request will carry the identification of component module 1 to be upgraded. The identification is used to uniquely represent the identity of component module 1, including but not limited to one or more of MAC address, IP address or port number. The remote host can communicate with the target component module to be upgraded based on a network communication protocol, such as the modbus RTU protocol.

[0049] S202: Send a download request to the remote host in response to the upgrade request.

[0050] The download request is used to request the remote host to transmit the upgrade package to the target component module. The download request carries the identifier of the target component module so that the remote host can determine the upgrade package to be sent according to the identifier of the target component module.

[0051] S203: Receive an upgrade package of the target component module sent by the remote host in response to the download request.

[0052] The transmission protocol of the upgrade package is the Ymodem protocol, which is an error correction protocol. The modem using larger data blocks adopts this protocol to obtain higher work efficiency. The modem using the Ymodem protocol sends data in blocks of 1024 bytes. If the data is successfully received, no confirmation message will be sent. If the data is not successfully received, a non-confirmation (NAK) message will be sent and a retransmission process will be executed. The upgrade package can be an incremental upgrade package or a full upgrade package. The incremental upgrade package is the incremental data of the application stored on the remote host and the application stored on the target component module. The full upgrade package is the upgrade package of the complete new application.

[0053] S204: After detecting that the upgrade package of the target component module has been completely transmitted, perform integrity check on the upgrade package of the target component module.

[0054] The integrity check is used to check whether the upgrade package received by the target component is identical to the upgrade package stored on the remote host. The integrity check may adopt any existing integrity check algorithm, such as the CRC32 check algorithm.

[0055] S205: If the integrity check succeeds, update the pre-stored old application program according to the upgrade package of the target component module to obtain a new application program, and run the new application program on the target application program.

[0056] Among them, the pre-stored old application is the application currently stored in the target component module (the application existing at the time of update and upgrade). If the integrity check of the upgrade package of the target component module is successful, the new application is used to update the application currently stored in the target component module according to the upgrade package from the remote host. If the upgrade package is an incremental upgrade package, it is necessary to merge the incremental upgrade package and the old application currently stored in the target component module to obtain the new application; if the upgrade package is a full upgrade package, the full upgrade package is decompressed to obtain the new application, and then the new application is run on the target component module to complete the program upgrade of the target component module.

[0057] In one or more embodiments, the receiving the upgrade package of the target component module sent by the remote host in response to the download request includes:

[0058] Receiving a plurality of data packets sequentially sent from the remote host;

[0059] The multiple data packets are reassembled to obtain the upgrade package.

[0060] For example, the network communication protocol between the remote host and the target component only allows a 128K data packet to be transmitted at a time, and the size of the upgrade package is much larger than 128K. In this case, the remote host will segment the upgrade package to obtain multiple 128K data packets. The size of the last data packet may be less than 128K, and the insufficient part can be filled with a specified padding character. Then the multiple data packets are numbered in sequence, for example: numbered from 1, 2, 3, ..., and then multiple data packets are transmitted to the target component module in order from small to large. The target component module receives the multiple data packets sent by the remote host in sequence, and reassembles the multiple data packets in order from small to large to obtain an upgrade package. If the specified padding character is stored in the last data packet, the padding character needs to be removed.

[0061] Among them, each data packet will carry a stop transmission indicator. When the value of the stop transmission indicator is a preset value, it indicates that the data packet is the last data packet, that is, the transmission process of the upgrade package is completed. For example: the target component module will detect the stop transmission indicator every time it receives a data packet. When the value of the transmission indicator is 1, it means that the data packet is the last data packet, and then all previously received data packets will be reassembled to obtain a complete upgrade package.

[0062] In one or more embodiments, the updating of the pre-stored old application program to obtain the new application program according to the upgrade package of the target component module further includes:

[0063] A stop-work instruction is sent to other component modules in the financial robot except the target component module; wherein the stop-work instruction is used to instruct the other component modules to stop working.

[0064] After the new application program is successfully executed, a work resumption instruction is sent to the other component modules; wherein the work resumption instruction is used to instruct the other component modules to resume work.

[0065] Among them, each component module can only work properly with the cooperation of each other. During the upgrade process of the target component module of the financial robot, other component modules of the financial robot cannot work normally. During the upgrade process, the target component module sends a stop work instruction to other components after receiving the upgrade request. Then, after completing the upgrade process, the target component module sends a resume work instruction to other component modules through the modbus bus. Specifically, the target component module sends a resume work instruction to other component modules through the modbus bus after successfully running the new application. In this embodiment, each component upgrade module can be upgraded in parallel to improve the upgrade efficiency of each component module in the financial robot.

[0066] In one or more embodiments, the storage space of the component module is divided into a first storage space and a second storage space.

[0067] The first storage space and the second storage space are two independent storage spaces, which can be located in two different memories or in the same memory. The first storage space is used to store the upgrade package downloaded from the remote host, and the second storage space is used to store the current application in the target component module.

[0068] In one or more embodiments, the updating of the pre-stored old application program according to the upgrade package of the target component module to obtain the new application program includes:

[0069] Acquire the old application currently stored in the target component module in the second storage space;

[0070] The upgrade package and the old application stored in the first storage space are incrementally updated to obtain a new application.

[0071] The incremental upgrade package is the differential data between the application stored on the remote host and the application stored on the target component module. The remote host can reduce the amount of transmitted data by sending the incremental upgrade package to the target component module.

[0072] In one or more embodiments, further comprising:

[0073] When the integrity check fails, sending a check failure message to the remote host, obtaining the old application from the second storage space and running it on the target component module; or

[0074] When the integrity check succeeds, the new application is overwritten into the second storage space.

[0075] When the integrity check fails or the new application fails to run on the target component, a check failure message is sent to the remote host. After receiving the check failure message, the remote host resends the upgrade package to the target component module, and then uses Figure 2 The upgrade process is performed again in the same manner as in the example. At the same time, the target upgrade module obtains the previous old application from the second storage space and uses the old application to run. If the integrity check succeeds, the old application is overwritten and written to the second storage space.

[0076] The beneficial effects of the present application include: by using Ymodem as the transmission protocol to transmit the upgrade package, the communication between the component module of the financial robot and the remote host is realized through the ModbusRTU networking method, and only after the upgrade is successful, the pre-stored old application is updated according to the upgrade package of the module of the target component to obtain the new application, thereby ensuring the security and reliability of the application on the component module of the upgraded financial robot. In addition, if an abnormal situation occurs during the upgrade of the application of the component module (including when the integrity check fails or the new application fails to run on the target component), the application of the component module is restored to its original state, thereby further ensuring the security and reliability of the application on the component module of the upgraded financial robot.
