Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0021] Figure 3 It is a structural schematic diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION

[0022] At present, the deployment of application software of the railway signal general safety system needs to rely on hardware interfaces. The storage hardware device containing the application software is copied to the corresponding hard disk location of the railway signal general safety system server through the hardware interface. That is, each software update needs to be manually updated on each server, which not only consumes a lot of resources and time, but also cannot intuitively receive feedback information on whether the data has been copied in correctly.

[0023] In the process of writing and optimizing the application software in the railway signal universal safety system, each software update needs to be synchronously redeployed to the corresponding server operating environment and completed. At present, this deployment method is based on the matching of existing embedded operating systems and server devices, which is a relatively primitive startup method of directly reading from the hard disk.

[0024] It can be seen that the shortcomings of the existing technical solutions mainly include the following points: 1. Every time the R&D personnel compile new software, they need to copy it to the storage device (U disk, mobile hard disk, etc.); 2. Using storage devices to copy data requires sequential operation on all servers used by the railway signal universal safety system, which takes a lot of time; 3. During the copy-in process, there is no correct feedback and verification cannot be performed before restarting the environment.

[0025] 4. Storage devices are at risk of being infected by computer viruses and malicious scripts, and are less secure; 5. Existing technology requires that all hardware servers used in future railway signal universal safety systems must have supported storage device interfaces, which is somewhat restrictive; 6. The existing technology directly operates on hardware storage, which may affect the equipment when used on site and has poor isolation.

[0026] In view of the above shortcomings, the present invention aims to propose a method for remote deployment of application software of a railway signal universal safety system. By utilizing the characteristic that the railway signal universal safety system uses the same network, the network transmission protocol followed by the software in the railway signal universal safety system is deployed to the server using a remote network service, and then the application software of the railway signal universal safety system can be remotely deployed through any client.

[0027] The invention proposes a method for remote deployment of application software of a universal railway signal safety system. Firstly, it solves the problem that R&D personnel need to frequently use storage devices to perform on-site deployment on each server each time, thus saving a lot of time and resources. Secondly, a verification code mechanism is added to the network transmission protocol, so that information feedback on whether the software is successfully updated can be provided through the verification code. Thirdly, due to the unified use of the internal network, the risk of hardware equipment being infected with viruses is reduced, thereby improving security. Finally, even if the hardware server does not support the storage device interface, it will not affect the software deployment, and there is no need to perform on-site operations on the server device, which will not affect the operation of the device and improve isolation.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Combine the following Figures 1 to 3 The invention describes a method and device for remote deployment of application software of a universal railway signal safety system.

[0030] Figure 1 : is a flow chart of a method for remote deployment of application software of a railway signal universal safety system provided by the present invention, such as Figure 1 As shown, the method comprises the following steps: Step 101: Determine the network transmission protocol supported by all servers and all clients in the railway signal universal safety system.

[0031] The railway signal universal safety system in the prior art includes multiple servers and multiple clients (including computers, mobile phones, and tablets, etc.), and multiple devices often follow different network transmission protocols, such as TCP protocol and UDP protocol, etc. Due to following different network transmission protocols and data interaction mechanisms in the railway signal universal safety system, it is impossible to remotely deploy application software on multiple servers and multiple clients in the railway signal universal safety system. For example, when compiling a specific software, it is necessary to first configure a specific compilation environment, and then copy the compiled software to the corresponding hard disk location of the server through the hardware interface supported by the server, and manually implement the software update, but it is impossible to directly transfer files between multiple devices to achieve remote deployment of application software.

[0032] In order to remotely deploy application software on all servers and all clients in the railway signal universal safety system, the embodiment of the present invention needs to modify the original network transmission protocol in the railway signal universal safety system to obtain a network transmission protocol supported by all servers and all clients in the railway signal universal safety system. The following is an example of file transmission.

[0033] For example, when performing file transfer, it is necessary to modify the original File Transfer Protocol (FTP) and add a file transfer verification mechanism so that all servers and all clients in the railway signal general safety system support the modified FTP and ensure that all servers and all clients follow the modified FTP during operation. Then, files can be transferred through the modified FTP, thereby realizing remote deployment of application software.

[0034] Step 102: Based on the network transmission protocol, remotely deploy the application software in all the servers through any client among all the clients.

[0035] After determining the network transmission protocol supported by all servers and all clients in the railway signal universal safety system, deploy this network transmission protocol to the corresponding locations of all servers and all clients, and then the application software in all servers can be remotely deployed through any of the clients.

[0036] The method for remote deployment of application software of a universal railway signal safety system provided by the present invention first determines the network transmission protocol supported by all servers and all clients in the universal railway signal safety system, then deploys the network transmission protocol to all servers and all clients, and finally uses any client among all clients to remotely deploy the application software in all servers. It does not need to rely on storage hardware devices or manually update on each server, thus saving time and resources and improving the convenience, security and isolation when updating the application software of the universal railway signal safety system.

[0037] Optionally, the remote deployment of application software in all servers through any one of all the clients based on the network transmission protocol includes: Based on the network transmission protocol, generate a protocol code corresponding to the network transmission protocol; Deploy the protocol code to all servers and all clients in the railway signal universal safety system; Based on all servers and all clients in the railway signal universal safety system after deployment, the application software in all servers is remotely deployed through any client among all the clients.

[0038] Specifically, based on the network transmission protocol that has been determined to be supported by all servers and all clients in the railway signal universal safety system, a protocol code corresponding to the network transmission protocol is generated; Deploy the generated protocol code to all servers and all clients in the railway signaling universal safety system; Based on all servers and all clients in the railway signal universal safety system after deployment, the application software in all servers is remotely deployed through any of all clients.

[0039] For example, the protocol code corresponding to the network transmission protocol is written in C / C++, and the completed protocol code is deployed to all servers and all clients in the railway signal general safety system, and then the new application software is compiled on any of the clients. After the compilation is completed, the new application software can be synchronously deployed to all servers, thereby realizing remote deployment.

[0040] The embodiment of the present invention first generates a protocol code corresponding to the network transmission protocol based on the network transmission protocol that has been determined to be supported by all servers and all clients in the railway signal general safety system, and then deploys the generated protocol code to all servers and all clients in the railway signal general safety system, and then remotely deploys the application software in all servers through any of all clients, thereby getting rid of the dependence on hardware interfaces and storage devices when deploying application software in the railway signal general safety system in traditional technologies, saving time and resources, making the deployment of application software in the railway signal general safety system more convenient, and improving the efficiency of application software deployment in the railway signal general safety system.

[0041] Optionally, the network transmission protocol includes a verification mechanism.

[0042] Specifically, in the embodiment of the present invention, a verification mechanism is added to the network transmission protocol supported by all servers and all clients in the railway signal universal safety system.

[0043] Optionally, the verification mechanism is used to verify the correctness of data sent by any client among all the clients to the server through a verification code.

[0044] Specifically, there are multiple verification mechanisms. In the embodiment of the present invention, a block check character (Block Check Character, BBC) verification mechanism and a cyclic redundancy check (Cyclic Redundancy Check, CRC) mechanism are taken as examples for introduction.

[0045] For example, using the BBC checksum mechanism, a checksum character is obtained by performing a specific operation on each byte in a group of data blocks, and the checksum character is transmitted or stored together with the data block. Then, the same operation is performed on the data block at the receiving end, and the operation result is compared with the received checksum character to determine whether an error occurs in the data transmission or storage process.

[0046] For another example, using the CRC mechanism, that is, selecting a data to be checked to generate a binary polynomial, associating the transmission data with the result of the polynomial to form a checksum, and then sending the checksum together with the transmission data to the receiving end. When the receiving end receives the transmission data, it also calculates the checksum corresponding to the data to be checked in the received transmission data, and compares it with the checksum sent before. If they are inconsistent, it means that an error occurred during the data transmission process. If they are consistent, it means that the data transmission is correct.

[0047] In an embodiment of the present invention, the CRC mechanism in the above-mentioned verification mechanism is used (in other cases, other verification mechanisms may also be selected) to perform correctness verification on data sent to the server by any client among all the clients, so as to intuitively receive feedback on the correct copy-in of data sent by the client to the server. For example, if the data sent is an application software update data packet, information feedback can be received on whether the server has received the accurate application software update data packet and whether the application software has been successfully updated.

[0048] The embodiment of the present invention adds a verification mechanism to the network transmission protocol and uses a verification code to verify the correctness of data sent by any client among all clients to the server, so that during the process of remote deployment of application software in the railway signal universal safety system, the client can receive information feedback on whether the data transmission is correct or not, so that the success of the software deployment can be verified before restarting the railway signal universal safety system environment, saving time and resources.

[0049] Optionally, the remote deployment of application software in all servers through any client among all the clients includes one or more of upgrading application software, downloading application software and deleting application software.

[0050] Specifically, the application software in all servers is remotely deployed through any of all clients, wherein the remote deployment of the application software includes remotely upgrading the application software at the client, remotely downloading the application software at the client, and remotely deleting the application software at the client.

[0051] For example, at any client in the railway signal universal safety system, a software upgrade data package is compiled for the original application software and sent to all servers through the client, thereby realizing remote update or upgrade of the application software in all servers and clients in the railway signal universal safety system.

[0052] For another example, any client in the railway signal universal safety system downloads new application software or deletes the original application software, and the corresponding changed data packets are synchronously deployed to all servers, thereby realizing remote deployment of application software of the railway signal universal safety system.

[0053] The embodiment of the present invention remotely deploys the application software in all servers through any of all the clients, thereby realizing remote upgrade, remote download, and remote deletion of the application software of the railway signal universal safety system, without relying on the hardware interface supporting the storage device in the hardware server, and without manually updating on each server, thereby improving the deployment efficiency and convenience of the application software of the railway signal universal safety system. In addition, during the deployment of the application software, the operation of the equipment will not be affected, thereby improving safety.

[0054] Optionally, before remotely deploying the application software in all the servers through any of the clients, the method further includes: It is determined that all servers and all clients in the railway signal universal safety system belong to the same network.

[0055] Specifically, before remotely deploying the application software in all servers through any of all clients, it is also necessary to ensure that all servers and all clients in the railway signal universal safety system belong to the same network.

[0056] Based on any of the above embodiments, all servers and all clients in the railway signal universal safety system use the railway system internal network. Before using any client to remotely deploy the application software in all servers, it is determined that all servers and all clients use the same local area network in the internal network, thereby reducing the risk of server storage devices being infected by computer viruses or malicious scripts, and improving the isolation and security of the railway signal universal safety system.
