Description

TECHNICAL FIELD

[0001] The present application relates to the field of video monitoring technology, and in particular to a data transmission method and device, electronic equipment and a storage medium. BACKGROUND

[0002] The vehicle control system is a most commonly used system platform for traffic police, which can display vehicle information, illegal information and pictures, and has functions of vehicle control and capture, route analysis, vehicle statistics, etc. Each manufacturer uploads the captured vehicle data and pictures to the vehicle control system. Since network transmission of data is involved, a network gateway is introduced in networking to divide the networking into two parts, one part being an external network and the other part being an internal network. The front-end camera, industrial computer and other devices are in the external network (such as the Internet), and the vehicle control system platform is in the internal network (such as a local area network).

[0003] The most commonly used data transmission scheme at present is as follows: a database server is set in the internal network, and the network gateway opens the port of the database server to the specified devices in the external network, so that the external network devices can penetrate the network gateway and write the vehicle data and pictures into the database server.

[0004] However, this method still has some disadvantages: the network gateway opens the port of the database server to the specified devices in the external network, so that some specified external network devices directly write data to the internal network database server without passing through the network gateway, which reduces the security of data transmission; moreover, the time consumption for writing vehicle data and pictures into the database depends on the disk IO performance of the database server, and with the increase of the database data volume, the time consumption for writing increases, which affects the real-time performance of data transmission; if the data writing fails, the external network devices cannot know it, and the data cannot be re-sent, which results in data loss and affects the integrity of data.

[0038] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, not all the structures.

[0039] Figure 1 is a flowchart of a data transmission method according to the first embodiment of the present application. The present embodiment can be applied to the case of realizing safe and fast data transmission through the docking server of the intranet and the extranet. The method can be executed by a data transmission device, which can be realized in software and / or hardware, and can be integrated in an electronic device, such as a server.

[0040] In the embodiments of the present application, vehicle data (for example, vehicle passing data, illegal data) and snapshot pictures need to be uploaded to a vehicle control system platform deployed in an internal network from an external network. Although a network lock safeguards the security of the network in networking, it complicates the entire networking. Currently, the vehicle control system usually has two requirements for uploaded vehicle data and pictures, one is real-time, which ensures that the vehicle data and pictures are uploaded to the vehicle control system platform within 8 seconds, and if the delay is large, the control function cannot be used; the other is integrity, the vehicle data and pictures cannot be lost, otherwise the historical data analysis, illegal judgment and other functions will be affected. Based on this, in order to ensure the real-time and integrity of the uploaded vehicle data and pictures, the inventors creatively propose a data transmission method, specifically, a first docking server is deployed in the internal network, and the first docking server is configured with a first WebService server; a second docking server is deployed in the external network, and the second docking server is configured with a second WebService client, so that the first docking server and the second docking server can perform data transmission based on the WebService protocol.

[0041] It should be noted that, in order to ensure that the first docking server and the second docking server can perform data transmission based on the WebService protocol, it is necessary to first establish a connection between the first WebService server and the second WebService client. Optionally, the process of establishing the connection includes: the first docking server starts the first WebService server, and the second docking server starts the second WebService client; the first docking server receives the connection message sent by the second WebService client on the second docking server and forwarded by the network lock, and replies to the response message, that is, the response message is forwarded to the second docking server through the network lock, so as to establish a connection between the first WebService server and the second WebService client.

[0042] On the basis of the above, as shown in Figure 1 The data transmission method specifically includes the following processes:

[0043] S101, receiving the to-be-uploaded data sent by the second WebService client on the second docking server and forwarded by the network lock through the first WebService server, and saving the to-be-uploaded data.

[0044] In the embodiment of the present application, the to-be-uploaded data is obtained by the second docking server from an external network platform. The external network platform is a platform deployed in the external network for storing various data collected by a front-end collector, and is optionally an entity server device. That is, after the front-end collector (for example, a camera) collects picture data and vehicle data, the picture data and the vehicle data are stored in the external network platform through a transmission protocol (for example, a tcp protocol), so that the external network platform forwards the stored data to the second docking platform.

[0045] Further, the to-be-uploaded data can be determined according to the storage pressure of the vehicle control system platform (i.e., the internal network platform). If the storage of the vehicle control system platform is sufficient, the to-be-uploaded data is optionally a combination of vehicle data and picture data; if the storage of the vehicle control system platform is insufficient, the to-be-uploaded data is optionally vehicle data and a picture URL (Uniform Resource Locator, Uniform Resource Locator system); wherein the vehicle data is optionally structured text data, including vehicle brand, license plate number, and illegal information, etc., and the picture URL is suitable for representing the storage location of the picture data in the external network platform.

[0046] In the embodiment of the present application, in order to further ensure the real-time performance of data transmission, the second WebService client on the second docking server can create multiple data transmission threads in advance, and then send the to-be-uploaded data to the gatekeeper in parallel through multi-threading, and after being verified by the gatekeeper, the to-be-uploaded data sent in parallel is forwarded to the first WebService server of the first docking server, so that the first WebService server receives the to-be-uploaded data in parallel, thereby ensuring the speed of data transmission, and further ensuring the real-time performance of data transmission.

[0047] After the first docking server receives the to-be-uploaded data, it can save the data in its local database or disk, so as to subsequently upload the receipts saved in the database or disk to the vehicle control system platform.

[0048] S102, the saving result is fed back to the second docking server through the gatekeeper, so that the second docking server determines whether the to-be-uploaded data needs to be resent according to the saving result.

[0049] The saving result can optionally include saving success and saving failure, and the first docking server can feed back the saving result to the second docking server through the gatekeeper, so that the second docking server knows whether the to-be-uploaded data is successfully saved, and if not, the to-be-uploaded data is resent to ensure the integrity of the to-be-uploaded data.

[0050] In the embodiment of the application, the data transmission between the first docking server and the second docking server is forwarded through the gateway, ensuring the security of the data; and the data transmission adopts the WebService protocol, so that the data is sent in the form of data stream in parallel, ensuring the real-time performance of the data transmission; and the saving result of the data is fed back to the second docking server, so that the second docking server re-sends the data when the saving fails, ensuring the integrity of the data.

[0051] Figure 2a is a flow chart of the data transmission method according to the second embodiment of the application, which is optimized on the basis of the above-mentioned embodiment, and the method comprises the steps of Figure 2a

[0052] S201, receiving, by the first WebService server, the to-be-uploaded data sent by the second WebService client on the second docking server and forwarded by the gateway.

[0053] The second docking server is deployed in an external network, and the external network is separated from an internal network by the gateway.

[0054] In the embodiment of the application, the to-be-uploaded data comprises vehicle data and picture data; the first docking server further comprises a local memory disk and a local database. The local memory disk is formed by dividing the memory, and optionally divided by using the SoftPerfect ram disk software, and the size is exemplarily 24 GB (the first docking server has a total of 32 GB memory, 24 GB is used for caching pictures, and 8 GB is used for system use). The local memory disk has the advantage of fast read-write speed. The local database is used for saving structured data.

[0055] S202, caching the picture data to the local memory disk and obtaining the cache path of the picture data.

[0056] Since the writing of the vehicle data and the picture into the database needs time, the time consumption depends on the disk IO performance of the database server, and with the increase of the database data volume, the writing time consumption will also increase, and the picture is large, and the writing into the database is slow, so the real-time performance of the data transmission will be affected. Based on this, in order to improve the real-time performance of the data transmission, the inventors creatively propose to save the vehicle data and the picture data separately. Specifically, the picture data is cached to the local memory disk, and since the local memory disk has fast read-write speed, the time consumption is short compared with the storage in the database, thereby ensuring the real-time performance of the output transmission.

[0057] Further, after the picture data is cached in the local memory disk, the cache path of the picture data in the local memory disk is obtained. It should be noted that the reason for obtaining the cache path of the picture data in the local memory disk is to ensure that the corresponding picture data can be quickly found according to the cache path subsequently.​

[0058] S203, write the vehicle data and the cache path into the local database.

[0059] The vehicle data and the cache path are optional structured text data, which are written into the local database at a high speed and with a short time consumption, thereby ensuring the real-time data transmission.

[0060] S204, feed the saving result to the second docking server through the gatekeeper, so that the second docking server judges whether the to-be-uploaded data needs to be re-sent according to the saving result.

[0061] The specific process is described in the above embodiment, which is not repeated here.

[0062] S205, query the cache path of the to-be-uploaded vehicle data and the picture data in the database, and acquire the corresponding picture data from the local memory disk according to the cache path.

[0063] In the embodiment, the data in the local database can be identified in different states according to different flag bits, wherein the states include a to-be-uploaded state, an uploaded state, a deleted state and the like. After the to-be-uploaded data is saved in the first docking server through the steps S201-S203, the cache path of the vehicle data and the picture data in the to-be-uploaded state in the database is queried, and the corresponding picture data is acquired from the local memory disk according to the cache path.

[0064] S206, upload the vehicle data and the acquired picture data to the intranet platform.

[0065] After the to-be-uploaded vehicle data and the picture data are acquired, the vehicle data and the picture data can be uploaded to the intranet platform through a preset transmission protocol, wherein the intranet platform is a platform in which the vehicle control system is deployed.

[0066] S207, judge whether the data is uploaded successfully.

[0067] Optionally, the first docking server and the intranet platform have a response mechanism, and the first docking server can determine whether the uploading is successful according to the information fed back by the intranet platform. If not, S208 is executed, and if yes, S209 is executed.

[0068] S208, re-upload the vehicle data and the acquired picture data, and the number of repeated uploading is less than a preset number threshold.

[0069] If the uploading fails or times out, the vehicle data and the obtained picture data need to be re-uploaded. It is to be noted that, in order to avoid the abnormal situation of infinite retransmission, a preset number threshold is set in advance, that is, the maximum number of allowed retransmissions is equal to the preset number threshold. If the retransmission fails when the number of retransmissions is equal to the preset number threshold, the uploading of the data and the picture is abandoned, and is marked as uploading failure, and other data is continuously uploaded; if the uploading succeeds when the number of repeated uploading is less than the preset number threshold, S209 is executed.

[0070] S209, marking the cache path of the vehicle data and the picture data as uploaded in the local database.

[0071] After the vehicle data and the obtained picture data are uploaded to the intranet platform, the cache path of the vehicle data and the picture data is marked as uploaded in the local database, so as to avoid subsequent repeated uploading.

[0072] Further, in order to clearly describe the process of data transmission, refer to Figure 2b which shows a flowchart of data transmission. Specifically, the first docking server and the intranet platform are deployed on the intranet side, the second docking server, the extranet platform and the front-end camera are deployed on the extranet side; the intranet and the extranet are separated by a network lock. The front-end camera collects the data of the passing vehicle, such as license plate information, vehicle brand, whether illegal and the captured picture; the vehicle data and the picture are sent to the extranet platform through a transmission protocol. The extranet platform sends the saved to-be-uploaded data to the second docking server, the second docking server sends the to-be-uploaded data to the network lock through the second WebService client, the network lock verifies and sends the to-be-uploaded data to the first WebService server on the first docking server, then saves the received picture data in the local memory disk, and saves the cache path of the picture and the vehicle data in the database; then, the to-be-uploaded vehicle data and the cache path are queried from the local memory disk, the corresponding picture is obtained, and the obtained picture and the vehicle data are uploaded to the intranet platform.

[0073] In the embodiment of the application, the structured vehicle data and the picture data are separated, and the picture data is cached in the local memory disk. Since the memory disk has high reading and writing speed, the caching of the picture consumes less time, and the real-time performance of data transmission is ensured. At the same time, the cache path of the structured vehicle data and the picture data is saved in the database. Since the data volume of the cache path of the vehicle data and the picture data is small, the writing speed into the database is fast, and the output transmission speed is ensured. The docking server and the platform on the intranet have a response mechanism, can realize data and picture retransmission, and ensure the integrity of the data.

[0074] Figure 3is a logic flow chart of the data transmission method according to the third embodiment of the present application, which is optimized on the basis of the above-mentioned embodiments, see Figure 3 The method logic comprises:

[0075] Firstly, the second docking server is started, and a second WebService client is started, and a multi-thread is created, so as to send the to-be-uploaded data in parallel through the multi-thread subsequently; the first docking server is started, and a first WebService server is started. The second WebService client sends a connection message to the gateway, the gateway verifies and forwards the connection message to the first WebService server, and replies an answer message to the gateway after the connection is successful, and the gateway sends the answer message to the second docking server, so as to establish the second WebService client and the first WebService server.

[0076] Further, the front-end camera transmits the to-be-uploaded picture and vehicle data to the external network platform, and optionally, a TCP protocol is used for transmission. The second docking server sends the to-be-uploaded data to the server address of the first docking server in parallel based on the WebService protocol through the multi-thread. Specifically, the to-be-uploaded data is sent to the gateway first, and after verification by the gateway, the to-be-uploaded data is forwarded to the first WebService server of the first docking server.

[0077] After receiving the to-be-uploaded data, the picture in the to-be-uploaded data is saved in the local memory disk, and the vehicle data and the picture in the to-be-uploaded data are saved in the local database in the cache path of the memory disk. Further, a saving result message is returned to the second docking server, specifically, the saving result message is sent to the gateway first, and after verification by the gateway, the saving result message is forwarded to the second docking server, and the second docking server judges whether the sending is successful or failed according to the saving result message. If failed, a re-sending process is started.

[0078] Further, the first docking server queries the database, and uploads the to-be-uploaded vehicle data in the database and the picture data corresponding to the to-be-uploaded cache path to the memory platform. It needs to be explained that if the uploading fails or times out, the data is re-uploaded. In order to avoid the abnormal situation of unlimited retransmission, the number of re-uploading is less than a preset number threshold. According to the feedback message of the memory platform, the flag bit of the corresponding data in the database is updated, that is, the cache path of the vehicle data and the picture data is marked as uploaded in the local database. And the specific logic can be executed according to the numbers in Figure 3 from 0 to 13.

[0079] In the embodiments of the present application, the structured vehicle data and the picture data are separated, the picture data is cached in the local memory disk, and the cache picture consumes less time due to the fast reading and writing speed of the memory disk, thereby ensuring the real-time data transmission. Meanwhile, the cache paths of the structured vehicle data and the picture data are saved in the database, and the data volume of the cache paths of the vehicle data and the picture data is small, thereby ensuring the speed of output transmission. The first docking server and the second docking server have a response mechanism, which can realize the retransmission of the vehicle data and the picture data, thereby ensuring the data integrity. The first docking server and the intranet platform have a response mechanism, which can realize the retransmission of the data and the picture data, thereby ensuring the data integrity.

[0080] Figure 4 FIG. 4 is a logic flow diagram of a data transmission method according to the fourth embodiment of the present application. The embodiment is optimized on the basis of the above-mentioned embodiments, and the cache paths of the vehicle data and the picture data in the local database are marked as uploaded. A step of periodically deleting the uploaded picture is added, as shown in FIG. 4. Figure 4 The method comprises the following steps.

[0081] S401, receiving the to-be-uploaded data sent by the second WebService client on the second docking server through the first WebService server.

[0082] S402, caching the picture data to the local memory disk and obtaining the cache path of the picture data.

[0083] S403, writing the vehicle data and the cache path into the local database.

[0084] S404, feeding back the saving result to the second docking server through the gatekeeper, so that the second docking server judges whether the to-be-uploaded data needs to be re-sent according to the saving result.

[0085] S405, querying the cache paths of the to-be-uploaded vehicle data and picture data in the database, and obtaining the corresponding picture data from the local memory disk according to the cache path.

[0086] S406, uploading the vehicle data and the obtained picture data to the intranet platform.

[0087] S407, judging whether the data is uploaded successfully.

[0088] If not, S408 is executed, and if yes, S409 is executed.

[0089] S408, re-uploading the vehicle data and the obtained picture data, and the number of repeated uploading is less than a preset number threshold.

[0090] S409, mark the cache path of the vehicle data and the picture data as uploaded in the local database.

[0091] For the description of the processes of S401-S409, refer to the above embodiments, which will not be repeated here.

[0092] In the embodiments of the present application, the local memory disk only serves as picture cache and does not serve as long-term picture storage; meanwhile, the local memory disk is limited, and if not cleaned, it will be full very easily, causing abnormal conditions. Therefore, the local memory disk needs to be cleaned regularly, and in the embodiments of the present application, a picture cleaning thread is established after the first WebService server is started, and the picture cleaning thread cleans pictures by performing S410-S411.

[0093] S410, periodically acquire the cache path of the vehicle data and the picture data marked as uploaded from the local database.

[0094] S411, delete the picture data corresponding to the cache path in the local memory disk.

[0095] In the embodiments of the present application, if the cache path of a picture in the database is marked as uploaded, it indicates that the picture data corresponding to the cache path has been uploaded to the memory platform, and there is no need to continue to cache in the local memory disk. That is, in order to save the local memory disk space, the picture data corresponding to the cache path marked as uploaded can be deleted in the local memory disk.

[0096] Further, the first docking server can appear abnormal, and when the first docking server appears abnormal, the first docking server will not process the picture and the vehicle data, causing part of the pictures to be not uploaded to the intranet platform due to timeout, at this time, the picture cleaning thread needs to determine the timeout pictures in the local memory disk, clean the timeout pictures, so as to ensure that the memory disk can always write pictures and will not appear full. Specifically, refer to S412-S413.

[0097] S412, compare the cache time of all picture data in the local memory disk with the current time in turn.

[0098] S413, if the time difference between the cache time of a picture data and the current time is greater than a preset time length, delete the picture data.

[0099] S414, mark the cache path corresponding to all deleted picture data as deleted in the local database.

[0100] After the uploaded and timeout picture data in the local memory disk are deleted through S410-S413, the cache paths corresponding to all the deleted picture data are marked as deleted in the local database. Then the picture cleaning thread enters hibernation and waits for the next round of cleaning.

[0101] In the embodiment of the application, the uploaded picture data or the timeout picture data in the local memory disk are periodically deleted by the picture cleaning thread, so as to ensure that the space of the local memory disk is sufficient, thereby ensuring that the picture data can be quickly saved in the local memory disk, and further ensuring the real-time performance of data transmission.

[0102] Figure 5 is a flowchart diagram of a data transmission method according to the fifth embodiment of the application. The embodiment is an optimization based on the above-mentioned embodiments: in the embodiment of the application, the to-be-uploaded data includes vehicle data and a picture URL; the picture URL is used to represent the storage address of the picture in the external network platform, that is, the picture data is always saved in the external network platform; the external network platform is a platform deployed in the external network and used to save the data collected by the front-end collector; correspondingly, the saving of the to-be-uploaded data includes: saving the vehicle data and the picture URL in the local database of the first docking server, so as to send the vehicle data and the picture URL to the internal network platform, so that the internal network platform subsequently accesses the corresponding picture by sending a picture acquisition request.

[0103] In the embodiment of the application, the first docking server further includes a first WebService client and a second WebService server on the second docking server; the process of establishing a connection between the first WebService client and the second WebService server is similar to the process of establishing a connection between the first WebService server and the second WebService client, and will not be described herein.

[0104] On the basis of the above-mentioned content, the data transmission method further includes:

[0105] S501, receiving a picture acquisition request sent by the internal network platform.

[0106] In the embodiment of the application, since the data uploaded to the internal network platform is vehicle data and a picture URL, when a certain picture data is to be viewed in the internal network platform, the picture is to be acquired from the external network through a picture acquisition request. The picture acquisition request includes the picture URL of the target picture. Specifically, when the picture data is acquired, the internal network platform first issues a picture acquisition instruction to the first docking server.

[0107] S502, sending a picture acquisition request to the gateway by the first WebService client, and forwarding the picture acquisition request to the second WebService server on the second docking server by the gateway, so that the second WebService server acquires the corresponding picture from the external network platform according to the picture URL of the target picture.

[0108] After the first docking server acquires the picture acquisition instruction, the first docking server sends the picture acquisition instruction to the gateway, and forwards the picture acquisition instruction to the second WebService server on the second docking server after the gateway verifies the security, so that the second WebService server analyzes the picture acquisition instruction to acquire the picture URL of the target picture in the instruction, and then acquires the corresponding target picture from the external network platform according to the picture URL of the target picture.

[0109] S503, receiving the target picture sent by the second WebService client on the second docking server and forwarded by the gateway through the first WebService server, and feeding back the target picture to the internal network platform.
