In order to more clearly illustrate the technical solutions and advantages of the present invention, the following takes an LED screen b among an LED screen a, an LED screen b, and an LED screen c as a target LED screen, and a web page z, a web page x, and a web page x among web pages z, x, and v that are accessible to the target LED screen as a target web page, and a screen control method of a screen control system provided by an embodiment of the present invention is described in detail, as shown in fig. 6, specifically including the following steps:
step 601: and setting a request response service and a JavaScript script in the cloud server, and setting a control model comprising at least one field name.
Specifically, in order to realize remote control of the LED screen by the controller through the network without wiring a connection between the controller and the LED screen, a request response service may be provided to realize the IHttpHandler interface through a class of the request response service, through which an access request for handling its corresponding URL is made, and control of request information sent and sending of response contents is controlled. In addition, in order to facilitate management of the target parameters in the information issuance request from the controller, a control model including field names necessary for accessing the web page, for example, a control table may be provided so that the respective target parameters in the information issuance request are recorded in the control table, facilitating data management.
Step 602: at least one element information matching the web page x is stored in the controller.
In particular, the LED screen access web page requires basic element information so that the LED screen can access a target web page operated by a user. The element information necessary to access the web page may include: a page name of the web page, a page ID, a page function key name, a page function key ID, a page action type (e.g., "open page" LD and "refresh page" LC).
Step 603: when a user accesses the LED screen to access the web page x, determining an element set including at least one element information matched with the web page x through the controller.
Specifically, in order to facilitate the extraction of some information missed when the user operates the web page x, the matched element information of the web page x may be set as an element set, so as to perform parameter extraction based on the element set.
Step 604: current element information is determined from the set of elements by the controller.
Step 605: determining, by the controller, whether a user calls a target parameter corresponding to the current element information when accessing the web page x, if so, performing step 606, otherwise, performing step 607.
Specifically, when the element set includes "page name", "page ID", and "page function key name", one element information may be arbitrarily determined therefrom as the current element information, and then it is determined whether a target parameter corresponding to the current element information is called when the user operates the web page x, and if so, the target parameter may be recorded so that the LED screen b performs a corresponding action based on the target parameter. Otherwise, the current element information may be deleted from the element set, and then one more element information may be determined from the element set as the current element information.
Step 606: step 607 is performed by the controller recording the target parameter.
Step 607: the current element information is deleted by the controller and step 608 is performed.
Step 608: determining, by the controller, whether the number of element information in the element set is greater than 1, and if so, returning to step 604, otherwise, performing step 609.
Specifically, after a current element information is processed, if there is an element information in the element set, step 604 is continued until there is no element information in the element set.
For example, according to the operation of the user on the web page x, the target parameters of "baixxx" as the page name "," 356dd "as the page ID", and "play" as the page function key name can be extracted.
Step 609: and generating an information issuing request according to the recorded target parameters through the controller.
Step 610: and sending the information issuing request to the cloud server through the IHttpHandler interface through the controller.
Specifically, an information issue request including "baixxx" as a page name, "356 dd" as a page ID, and "play" as a page function key name is generated and sent to the cloud server through the IHttpHandler interface.
Step 611: and calling a request response service through the cloud server, and acquiring at least one target parameter for accessing the web page x from the information publishing request when the information publishing request sent by the controller is monitored.
In particular, the cloud server may invoke a request response service, e.g., a generic handler listens for request information from the controller. When the information publishing request is monitored, it may be determined whether a message format of the information publishing request is abnormal, for example, whether the message format is the same as a preset format agreed in advance, or whether information in the information publishing request includes parameters that must be called when the LED screen accesses a web page. If the message format of the information publishing request is normal, the information required for accessing the target web page can be extracted from the information publishing request, otherwise, prompt information with abnormal message format is returned to the controller.
Step 612: a set of element information including respective target parameters and a set including at least one field name model are determined.
Specifically, in order to facilitate management of the target parameters extracted from the information distribution request, the element information set and the model set including the field names may be set so that the acquired target parameters are recorded in accordance with the model set.
For example, the setting includes: the field names are a model set of "ID", "netpage page name", "page ID", "netpage function key name", "function key ID", "page action name", "jump parameter", "execution order", and "execution time".
Step 613: a current target parameter is determined from the set of element information.
Specifically, from the target parameters in the element information set: any one of "baixxx" as the "page name", "356 dd" as the "page ID", and "play" as the "page function key name" determines a current target parameter "baixxx".
Step 614: a current field name matching the current target parameter is determined from the set of models.
Specifically, the field name "netpage name" in the model set matches the current target parameter "baixxx", and thus, the field name "netpage name" is the current field name.
Step 615: and recording the current target parameter at the position indicated by the current field name in the control model.
Specifically, the current target parameter "baixxx" is recorded in a row or column indicated by the field name "netpage page name" in the control model.
Step 616: the current target parameter is deleted from the set of element information.
Step 617: it is determined whether the number of target parameters in the set of element information is greater than 1, if so, step 613 is performed, otherwise, step 618 is performed.
Specifically, after the current target parameter is recorded in the control model, in order to avoid repeatedly recording the parameter, the current target parameter "baixxx" may be deleted from the element information set, and the next current target parameter may be determined therefrom until the target parameters in the element set are all recorded in the control model.
Step 618: and calling a JavaScript script, controlling the LED screen b to execute actions according to the target parameters recorded in the control model, accessing the web page x, and displaying the accessed information.
Specifically, a JavaScript script is called, the LED screen b is controlled to access the target web page with the "baixxx" as the page name and the "356 dd" as the page ID, and the function key with the "play" as the page function key name is triggered to play the content in the target web page.
Step 619: and calling the JavaScript script, and deleting at least one target parameter recorded in the control model after the LED screen b executes the action.
Specifically, in order to prevent the LED screen b from accessing a wrong web page, resulting in issuing wrong information, the target parameters recorded in the control model are deleted after the LED screen b has executed the target parameters recorded in the control model.
