The principle of the invention is as follows:
in a traditional monitoring and early warning system, most of judgment triggering conditions of events are preset in advance, namely related event triggering conditions are hard coded at a server in advance, and if related data reach the triggering conditions, the related events are judged to be triggered. However, in the environment of the internet of things, the types of sensors of the devices are more, the geographical environment where the devices are located is complex, and whether the related remote sensing data trigger events or not often needs to be dynamically determined by combining various sensor data, the geographical positions and the time where the sensor data are located. For example, in the lighting dimming control system, traffic flow sensor devices arranged in a tunnel upload traffic flow data in real time, so that whether a traffic jam occurs in the current tunnel can be determined by uploading adjacent traffic flow sensor data, and the determination condition is not constant, but closely related to the variable parameters of the current time, the average vehicle speed and the vehicle type. In the conventional monitoring and early warning system, the service is restarted after each trigger condition change, so that the hard coding mode is heavy and inconvenient. The application layer strips the code from the event trigger rule information by using the event rule processor, extracts the event trigger rule information and stores the event trigger rule information into the database, and all subsequent event trigger conditions can configure related information through the imaging interface, so that event trigger condition data can be dynamically managed, and compared with a traditional mode, the event can be processed through the event rule processor more flexibly and conveniently.

and calculating a proportional value between the tunnel length and the tunnel panorama according to the tunnel length and the tunnel panorama length, and controlling the tunnel sliding distance after calculating the panorama sliding through mouse pressing, moving and putting down events, and assigning a value to a scrollLeft for controlling a rolling event, wherein the scrollLeft refers to the width of a page hidden at the left side of a rolling bar when the page is rolled to the right side by the rolling bar.
The implementation method of the page equipment and the running light off of the running light is as follows:
s1, judging a single-double tunnel of a page according to a value returned by a rear end;
s2, restoring and displaying the equipment on the page according to the size, the number and the type of field equipment, wherein the equipment is respectively arranged at the left side, the right side and the middle of a tunnel, the position of the equipment in the x direction is used for positioning, the position is determined by circulating equipment, the length of the tunnel is determined according to the offset value of the equipment by using offset values returned by data of 30, and the length of the tunnel is determined by adding the offset value of the longest equipment to the distance between an inlet and an outlet of the tunnel;
s3, the types of the equipment are basic, emergency and enhanced, which type of lamp is judged according to the data field, and the wattage of the corresponding equipment and the type of the equipment are displayed on the page;
s4, realizing the position of the vehicle on the page: judging whether a car exists or not through webSocket pushing, pushing a piece of data by each car, processing the car into a plurality of groups of data by the car and the lane related information in which direction the car is, recording the current time of getting off the car in the data by each car, enabling the running of the car on a page through a timer, and enabling the running position of the car to be: firstly, circulating a vehicle, wherein a current time is added when the vehicle circulates, and the current position of the vehicle is the current time of the vehicle minus the speed of the vehicle when the vehicle is added;
s5, realizing lighting of the vehicle: finding out 600 pixels in front of the automobile, lighting the lamp at 200 pixel positions in back of the automobile, and recording the lighted device;
s6, realizing the turning-on and turning-off of the vehicle running light: whether the lamp lighting device is contained in the lamp watching device or not, the lamp is turned on if the lamp is contained in the lamp watching device, and the lamp is turned off if the lamp is not contained in the lamp watching device.
