Problems solved by technology
However, in the process of driving, people often fail to find the speed limit sign in time due to negligence, or there are few vehicles ahead, and the driver of the vehicle unintentionally increases the speed of the vehicle.
Although with the advancement of science and technology, many roads have been installed with vehicle speed monitoring devices, but there are often only punitive measures and no early warning methods and measures, and lack of humanized care. Therefore, it is urgent to reform the existing speed limit signs and give voice prompts to drive at all times. Drivers maintain a safe speed, reduce traffic accidents, and protect people's lives and property

The invention discloses a road speed limit sign automatic recognition and voice prompting device. The device comprises a speed limit signal emitting end and a speed limit signal receiving and prompting end. The speed limit signal emitting end is in wireless communication with the speed limit signal receiving and prompting end. The speed limit signal emitting end is mainly composed of a first control circuit unit and an emitting circuit unit. The speed limit signal receiving and prompting end is mainly composed of a second control circuit unit, a receiving circuit unit and a voice prompting circuit unit. The speed limit signal receiving and prompting end is installed in a driving circuit of the speed meter of a vehicle. The speed limit signal emitting end is installed in a road speed limit denote. When the vehicle runs into a road speed limit area, the speed limit signal receiving and prompting end receives a speed limit signal of the speed limit signal emitting end and automatically performs voice prompting to warn a driver to slow down.
Description
technical field [0001] The invention belongs to the field of traffic intelligent management, and in particular relates to an automatic identification road speed limit sign and a voice prompting device. Background technique [0002] At present, automobiles have become the main means of transportation for people to travel, bringing convenience to people's lives. However, the accompanying traffic accidents have also increased rapidly, which has brought huge hidden dangers to people's lives and property. [0003] For the safety of roads and vehicles, traffic management departments have set up many signs on urban roads and high-grade highways, especially expressways, and voice prompts people to pay attention to safety, especially vehicle speed limit signs are set on each road section, so that voice Remind the driver of the vehicle to control the speed of the vehicle and drive carefully to avoid breaking the law or even causing traffic accidents due to speeding. Statistics show t...
