Description

technical field [0001] The invention relates to the field of intelligent public transport, in particular to an automatic bus stop reporting system with a fault analysis function. Background technique [0002] With the rapid development of the national economy, the population of each city is increasing rapidly year by year, and most people travel by public transport, so the development of urban public transport systems is also changing with each passing day. The most primitive method of station announcement is oral broadcast by the conductor on board the car. Now, the driver manually presses the button to announce the station. However, this method has many defects, for example, it will affect the driver's safe driving. The driver must not only drive, but also press the button. If the driver is not paying attention when driving, he may miss a stop or report a false alarm, which will cause inconvenience to passengers. Simultaneous positioning and playback functions are the key...

Problems solved by technology

The most primitive method of station announcement is oral broadcast by the conductor on board the car. Now, the driver manually presses the button to announce the station. However, this method has many defects, for example, it will affect the driver's safe driving. The driver must not only drive, but also press the button. The workload increases, and fatigue is easy, so that safe driving cannot be guaranteed, and the driver may be inattentive when driving, resulting in missed stops or false alarms, which will cause inconvenience to passengers

Simultaneous positioning and playback functions are the key points of the station announcement system. However, the current equipment does not have a circuit for fault detection of the two functions. Operators cannot know in time that the equipment is faulty, which affects normal use.

In addition, the current automatic bus station reporting system, because the work of the microprocessor is often interfered by the electromagnetic field from the outside, causing the program to run away and fall into an endless loop, the normal operation of the program is interrupted, and the microprocessor-controlled If the system cannot continue to work, it will cause the entire system to stagnate, and unpredictable consequences will occur, which will bring great hidden dangers to the use. Dangerous situations often occur and cause major losses.
