Intelligent station name reporting method

Abstract

The invention relates to an intelligent type station name broadcasting method, which comprises: receiving the signal form satellite by a navigation positioning device, obtaining the present longitude / latitude coordinate from the satellite signal; comparing the present longitude / latitude coordinate and the database in the navigation positioning device to judge whether a special positioning value exists, if yes, calculating the distance between the present position and the next target position (such as bus stop) according to the special positioning value and the present longitude / latitude coordinate; the microprocessor calculating out a adjusting residual distance parameter and the residual distance according to the received data from the navigation positioning device; when a traffic jam occurs in tunnel, transmitting the speed data detected by the sensing unit to the microprocessor to cause the microprocessor to adjust the above mentioned residual distance according to the detected speed data; judging whether to drive the image and sound apparatus according to the residual distance and the distance to the next target position; therefore, broadcasting the next station name to passengers at proper time.

Description

technical field [0001] The invention relates to a station name broadcasting method, in particular to an intelligent station name broadcasting method. Background technique [0002] Nowadays, means of transportation play a very important role in the daily life of ordinary people, especially for people in metropolitan areas. The thick result will inevitably form complicated traffic problems. Compared with traffic problems, the government has been advocating that people use public transportation as much as possible, such as: high-speed rail, MRT, trains, buses, etc. Among public transportation, buses are most closely related to daily life, and in the early days On the public bus, be provided with a flight attendant mostly, before the bus wants to arrive at the next stop, the station name of the next stop is informed by the flight attendant in person with oral broadcast, so that the passengers can prepare to get off the bus, however, With the rapid development of technology and...

AI Technical Summary

Problems solved by technology

[0003] see figure 1 As shown, the existing station name broadcasting system, the system 1 is provided with a satellite positioning device 11, the satellite positioning device 11 is to receive a positioning signal transmitted by the artificial satellite 14, and take out the current latitude and longitude coordinates and the current speed of the vehicle , the satellite positioning device 11 will analyze the current speed and the base speed, and the analyzed speed data will be sent to a microprocessor 12, so that the microprocessor 12 can use the speed data to calculate the forecast distance, so that the forecast distance and the arrival distance can be calculated according to the forecast distance. The distance of the next station is judged whether to drive a broadcast device 13, then when broadcasting the station name, the satellite positioning device 11 receives the positioning signal transmitted by the artificial satellite 14, and the satellite positioning device 11 extracts the current latitude and longitude coordinates and the current speed from the positioning signal , so that the satellite positioning device 11 can start to calculate the distance between the current position and the next station from the current latitude and longitude coordinates and the coordinates of the next station, the satellite positioning device 11 will analyze the current speed and the basic speed, and the speed data and distance after analysis The data will be transmitted to the microprocessor 12. After the microprocessor 12 calculates the forecast distance using the speed data, the station name announcement system 1 can drive the announcement device 13 according to the forecast distance and the distance to the next station, so as to inform the public on the bus. The station name of the passenger's next stop; yet, although the existing station name broadcasting system has quite convenient usability, there are still the following two disadvantages:

[0004] 1. When the bus is in the tunnel and encounters an unexpected situation (such as: traffic jam, traffic accident, fire, etc.), the bus does not arrive at the next stop, and the station name broadcast system 1 has driven the broadcast device 13 in advance, so that passengers The confusion makes it impossible to determine the exact time of the next stop, thus causing considerable inconvenience and distress to the passengers on the bus

[0005] 2. When the bus is driving in the tunnel section, the satellite positioning device 11 cannot transmit and receive signals with the artificial satellite 14, so that the satellite positioning device 11 cannot obtain the current latitude and longitude coordinates and the current speed. Therefore, the station name broadcasting system 1 causes False positives often occur
