Description

technical field [0001] The invention relates to the field of electronic control, and more specifically, relates to an automatic bus station announcement device. Background technique [0002] The bus has become the main means of transportation in the city now, and along with more and more stations of the bus, more and more people take the bus. Accurate bus station announcement has become an essential thing. [0003] When the current bus enters and exits the bus station, the bus driver manually controls and plays the prompts for entering and exiting the station. In this way, it often happens that the bus driver forgets to press the prompts or presses the wrong prompts when entering and exiting the station. Traveling by car will cause inconvenience. [0004] Chinese Utility Model Patent No. ZL200820162482.0 discloses an automatic bus station notification system, which includes a bus, a barcode reading sensor is placed on the bus chassis, and the barcode reading sensor reads t...

However, there are some shortcomings in this technical solution: the magnetic barcode is buried on the ground, and the vehicles come and go, which is very easy to be damaged; It is very inconvenient for passengers to use; the vibrator on the seat is just a decoration for standing passengers; and these devices consume energy and are costly to implement, which is not conducive to popularization

Although the method based on the satellite navigation system has high precision and the effect is good, there are also some defects in the automatic station reporting system based on the satellite navigation system. Because the receiver of the satellite navigation system needs to complete its own positioning, it needs to detect more than four navigation satellites. Visibility is maintained, but due to the dense high-rise buildings in the city, the navigation satellites are often blocked by the buildings, so that the receiver cannot complete the positioning because it cannot receive enough satellite signals, and the system cannot work at this time

[0006] Chinese Utility Model Patent No. 200820141643.8 discloses an automatic bus station announcer. The bus station is equipped with a read-only radio frequency card, and its platform information cannot be updated. Will no longer be used, increasing input costs
