in order to ensure the safety of the issued command, before issuing the command, a user needs to be ensured to have the authority of issuing the command. For example: the on-site terminal picture login user needs to have an operation desk operation authority, and the current operation place is an operation desk; the centralized control center terminal picture login user needs to have the operation authority of the operation center, and the current operation place is the operation center;

whether the current user has the authority of issuing the instruction or not can be reflected to the state of the button, such as: operable state-blue, inoperable state-gray; when the user does not have the authority of issuing the instruction, setting the color of the button to be gray and simultaneously setting the button to be in an unselected state;

adding OnClick events by using a JavaScript script, and writing BOOL quantity data True into corresponding point locations in the PLC;

in order to avoid the occurrence of the error control phenomenon, a user pops up a secondary confirmation window after issuing an instruction of opening a taphole in front of a furnace, writes BOOL amount data into a PLC after clicking 'confirm', and cancels the issued instruction of opening the taphole in front of the furnace if clicking 'cancel';

after the user successfully issues the furnace front iron notch opening instruction, the color of the button is green, which indicates that the furnace front iron notch opening operation is currently executed; the signal is a pulse level, and after a user sends a high-level signal, a low-level signal is recovered after 1 s;

after the command is successfully issued, if the PLC does not receive the pulse signal, popping up a popup window to remind that the command is issued but the PLC is not executed;

in the edge service, historical data is allocated and stored, and a trend control is used in configuration software to display the trend of the historical data;

connecting a furnace-front video AiBox by using a video service, acquiring a furnace-front real-time video stream by transmitting a monitoring point ID and a video URL, and calling a video plug-in an opened new window to display a real-time video;

through the transmitted monitoring point ID and video URL, through popup prompt and transmission start date, through calling a video plug-in to obtain a video stream within a specified time and display a historical video stream in a new page window;

the method comprises the steps of obtaining data of a plurality of state points from a PLC, obtaining current working state information from a combination of 'normal', 'system light fault' and 'system heavy fault' in a calculation mode, displaying the current working state information in a text control if abnormal information exists, and flashing red and yellow along with the abnormal information.

And adding an OnClick event to the text control in a JavaScript script, judging whether the current system alarm is a 'system light fault' or 'system heavy fault' when the user clicks the text control when abnormal alarm information occurs, and opening a module alarm information page in a modal mode.

The section can be realized by selectively using a real-time alarm control of configuration software, the alarm information of a variable point needs to be added in the variable management of the edge service, and when the variable value meets the alarm condition, the alarm of a corresponding type is triggered and displayed in an alarm list in real time;

detecting the value of a monitoring point for recording an event every 1s by using a timer function of configuration software, subscribing data of a related variable of the current time to the edge service when the value of the monitoring point meets the condition of recording data, recording the data of the current time by using a JavaScript, and then executing an SQL statement by using the JavaScript to insert the event with a data record into a relational database;

using a JavaScript script to execute an SQL statement to inquire the inserted event record with data from the relational database, and inserting the record into a table and displaying the record;

on-site simple tests are carried out, based on a 4G network, the time delay from a terminal to a center is 10ms-20ms, and occasionally, the condition of high time delay and even Timeout can occur; based on 2.4G and 5G WiFi networks, the time delay from a terminal to a center is 5-10ms, and occasionally high time delay occurs, based on 5G SA networking, the time delay from the terminal to the center is 1-2ms, and the conditions of high time delay and Timeout do not occur in a test time period, so that the WiFi network is more stable compared with a 4G network and WiFi network.

for safety, an operator operates the remote one-key iron notch under 5G by using the wireless handheld terminal, authorization is carried out in front of the furnace and a centralized control center, and after authority is given to both sides, the operator can operate the remote one-key iron notch in front of the furnace at a 5G wireless mobile terminal.

By utilizing the characteristics of low time delay and stability of the 5G technology, the time delay of using the wireless handheld terminal to run the picture to request data from the edge service and the center is low and stable, so that the phenomena of sudden interruption or time delay of data refreshing and the like can not occur when the 5G wireless handheld terminal is used.

Example 2:

the event report display module: after detecting that an alarm or other abnormal events are included, recording current time data, and inserting the current time data into a report to be displayed;

And acquiring fault signal point data, wherein the types of the signal points are all boul amount, judging the state of the current system according to the acquired data by using a binary or logic operation calculation method, and displaying the state of the current system in a text control.

For example: when a is 1, B is 0, B is 1, and a is 0, a is heavy fault, so by binary calculation: and C is 1A + 2B to obtain data, and when C is 1 light fault, C is 2 heavy fault.
