The method for updating the partition display of the LED display screen in the embodiment of the invention, as shown in fig. 1, comprises the following steps:
step S10: the playing box receives a program file issued by an external server in communication connection with the playing box; the program files include txt files and file display parameters.
The playing box establishes communication connection with a plurality of external servers, and the external servers in the embodiment are not limited to the servers running the program editing software, but can be servers generating the displayed updated information. For example, in a scenario where the station LED display screen displays traffic information, there is a server running program editing software, a server that performs real-time statistics on traffic information, and a server that performs statistics on station vehicle information, where these servers are all connected to the playing box in this embodiment in a communication manner, so as to be able to update the information of the relevant servers quickly.
Firstly, the playing box receives a program file issued by an external server, wherein the program file at least comprises a txt file and file display parameters, the txt file in the embodiment is a text file, and the file display parameters can comprise parameters such as text display coordinates, text display areas and the like.
Step S20: and selecting a txt file in a json format through the text attribute of the text window, wherein the txt file in the json format comprises an acquisition path for json format data.
The txt file defined by the embodiment of the invention comprises a format, namely a json format, and each server which is in communication connection with the playing box stores the txt file in the format, so that the playing box selects the txt file in the json format through the text attribute of the text window in the step, and the file comprises an acquisition path for json format data. The embodiment of the invention does not limit the acquisition path of json format data, and preferably sets the acquisition path as a url path. For example, the path for acquiring json format data from the txt file in json format is as follows:
JSON{“url”:“http://xx.xx.xx.xx/QueryRemainedParkingPlaceInfo”,“filter”:“$remainedParkingPlaceInfo[1].remainedParkingPlaceCnt”}JSON
in the above path, "xx.xx.xx.xx"represents the access address of the external server (which may be located in the same lan or in the public network, which requires the playing box to be networked to obtain)", "QueryRemainesParkingPlaceInfo" represents that the information to be obtained by this path is the remaining parking space information, specifically "remagnedParkingPlaceInfo [1 ]]"remaining parking space information contained".
The text window in this embodiment may be either a single-line text window or a multi-line text window, which is applicable to the method in this embodiment.
Step S30: and acquiring json format data stored in an external server in real time through an acquisition path to a preset data acquisition interface.
The embodiment of the invention realizes the rapid updating of the text content, the format of the rapidly updated content is set as json format data, the information of real-time statistics in the related server is stored as json format data, and the playing box obtains the json format data stored in the external server through acquiring the path in the step. For example, the content of json format data acquired by the playing box in this embodiment is as follows:
in combination with the acquisition path exemplified in step S20, if the json format data content acquired by the playing box is as above, the number of remaining parking spaces obtained by the acquisition path is 175. If the acquisition path is "remagnedpcompletion placeeinfo [0]", the number of remaining parking spaces obtained through the acquisition path is 20. If the acquisition path is "remagnedpcompletion placeeinfo [2], the number of remaining parking spaces obtained through the acquisition path is 74. If the acquisition path is "remagnedpcompletion placeeinfo [3], the number of remaining parking spaces obtained through the acquisition path is 78.
Before the play box of this embodiment acquires json format data, a data acquisition interface for communicating with an external server should be preset, and then the json format data is acquired actively in real time according to the acquisition path. Corresponding to the url path set in the above step, the json format data stored in the external server is acquired from the preset data acquisition interface by the way of GET request and the acquisition path.
In addition, if the playing box in the embodiment fails to acquire json format data from a certain external server, the playing box performs switching processing, and continues to acquire json format data from other external servers.
Step S40: and generating program display parameters correspondingly displayed in the text window according to the file display parameters and json format data, and transmitting the program display parameters to the LED display screen.

The playing box generates program display parameters which comprise text windows of contents to be updated by the LED display screen and related parameters of the contents to be updated and displayed. After the LED display screen acquires the program display parameters, the LED display screen performs corresponding display according to the program display parameters. In connection with the acquisition path exemplified in step S20, the LED display screen will update the number of remaining parking spaces corresponding to the "parking lot of the storage yard" to 175.
In the embodiment of the invention, if the fonts (font types, font sizes, font colors and the like) or the display effects (continuous up-shifting, down-shifting and the like) of the updated text are required to be reset, the program file is required to be issued again through the server running the program editing software, and manual operation setting is required by operators, otherwise, the embodiment of the invention generates the program display parameters according to the file display parameters contained in the program file received before after the json format data is acquired, and only the updating of the text content is realized.
