The invention provides an anti-dry-burning control method and device and a gas stove. The anti-dry-burning control method includes the steps that information relevant to current pot bottom temperatureis acquired; information relevant to current cookware weight is acquired; and according to the information relevant to the current pot bottom temperature and the information relevant to the current cookware weight, whether a dry burning condition is achieved currently or not is judged, and if yes, a gas valve is controlled to be closed. According to the anti-dry-burning control method, due to theadoption of the dual detection standards of the pot bottom temperature and the cookware weight, misjudgment and missing judgment on the dry burning condition in a pot can be effectively reduced.

The invention discloses a fatigue driving preventing device. The fatigue driving preventing device comprises a fatigue predicting module, a face information identifying module, a face information judging module and an inner alarming module. When the anti-fatigue driving device is used, the fatigue predicting module can conduct active prediction on a driver at intervals, and sends out fatigue test signals if conditions are met; the face information identifying module collects face information parameters and conducts analysis and contrast on the face information parameters and preset fatigue parameters through the face information judging module; if alarm sending-out conditions are met, the inner alarming module sends out an alarm to the driver. The fatigue driving preventing device does not need to be hung on the driver, so that subjective rejecting emotions of the driver are avoided. Besides, the fatigue predicting module is arranged in advance, and whether the driver is fatigued or not can be tested irregularly in the whole driving process of the driver, so that leakage judgment is reduced. Moreover, a pre-judging module and the judging module are simultaneously arranged, so that double insurance is achieved, and the probability of misjudgment is reduced. Finally, irregular monitoring is adopted, fatigue monitoring is not continually conducted in the whole driving process, so that resources are greatly saved, and requirements for devices are lowered.

The invention discloses a vehicle violation judgment method, device and equipment and a computer readable storage medium, and the method comprises the steps: carrying out the real-time tracking of a target vehicle when a first target vehicle is detected to be located in a first region of an intersection real-time image and a second target vehicle is detected to be located in a second region; whenthe first target vehicle turns left to enter a turning penalty area, obtaining a first evidence map; when the first target vehicle blocks a second target vehicle going straight to the turning penaltyarea in the left turning penalty area, obtaining a second evidence map; when the first target vehicle crosses a stop line located at the left intersection of the turning penalty area, obtaining a third evidence map; and according to the first evidence map, the second evidence map and the third evidence map, determining that the first target vehicle has a violation behavior of turning left withoutgoing straight. According to the technical scheme disclosed by the invention, the automatic judgment that the left turn does not make straight movement is realized, so that the human input and missedjudgment conditions are reduced.

The invention provides a geometric shape difference detection method and a device of electronic maps, which is used for the geometric shape difference detection of at least two electronic maps. In the method, each event spot is regarded as the current event spot, and the following operating steps are executed: a segment related to the current event spot is selected to form a first segment concourse from all the segments of the two electronic maps; a segment from the first segment concourse is selected to taken as the current segment; the current segment and the second segment concourse are compared to obtain a compared result, the segments of the first segment concourse except the current segment form the second segment concourse, and when the compared result shows no superposition segment is existed between the second segment concourse and the current segment, the current segment is estimated to be a difference segment. The invention reduces the geometric shape difference detection errors of the electronic maps, and the measuring efficiency is improved.
