The embodiment of the invention provides a mistaken touch prompting method, terminal equipment and a storage medium, and relates to the field of terminals. The method is applied to the terminal equipment, and comprises the following steps: when the terminal equipment is in an unlocking and screen-on state, determining whether the terminal equipment enters a shielding scene or not; if it is determined that the terminal equipment enters the shielding scene, determining a target event from the obtained touch events; and if it is determined that the terminal device is touched by mistake based on the target event and a plurality of preset judgment factors, generating a mistaken touch prompt. By means of the method, whether the terminal equipment is touched by mistake or not can be determined, the mistaken touch prompt is generated when it is determined that the terminal equipment is touched by mistake, and therefore it can be avoided that when the terminal equipment is touched by mistake, a ...

The invention relates to a method and a system for managing a road patrol task based on positioning. The method comprises the following steps of: 1, drawing a patrol road in an electronic map of a positioning system of a patrol vehicle; step 2, the positioning system automatically generates electronic patrol points with fixed spacing distances; step 3, after the patrol vehicle is started, uploading the position coordinates of the current patrol vehicle to the cloud system at regular intervals in the advancing process of the patrol vehicle; 4, the cloud system calculates the position coordinates uploaded by the patrol vehicle and the distance between the electronic patrol points in real time; 5, the calculated minimum distance is taken, the minimum distance and a set fixed threshold value are judged, if the minimum distance is smaller than the threshold value, the system judges that the corresponding electronic patrol point is patrolled, and otherwise, the system judges that the corresponding ...
