Maintenance monitoring of passenger carrying system

A maintenance monitoring device for passenger transport systems, characterized in that it comprises:

• a radio beacon, which is installed at an on-site check point of a passenger transport system and is used to broadcast radio signals toward its surroundings;
• and
• a personal mobile terminal, which is carried by maintenance workers and is used to sense radio signals when the maintenance workers approach the corresponding radio beacon:
• wherein the personal mobile terminal and/or the radio beacon is configured to calculate the time period information of radio signals broadcast by the corresponding radio beacon and continuously sensed by the personal mobile terminal;
• a maintenance management terminal, wherein the maintenance management terminal comprises:
• a time period information acquisition unit, which is used to receive the time period information from the personal mobile terminal or radio beacon;
• and
• a compliance determination unit, which is used to determine the compliance of the maintenance operations of the maintenance workers at an on-site check point of the corresponding radio beacon based on the time period information.

A maintenance monitoring method for passenger transport systems, characterized in that it comprises:

• sending radio signals broadcast by a radio beacon of an on-site check point installed on the passenger transport system;
• and
• calculating the time period information of continuously sensed radio signals broadcast by the corresponding radio beacon;
• generating maintenance track information corresponding to multiple on-site check points based on the chronological relationships of the time period information corresponding to these multiple on-site check points;
• determining compliance of maintenance operations of a maintenance worker at an on-site check point of the corresponding radio beacon based on the time period information and/or the maintenance track information.

A personal mobile terminal used to monitor the maintenance of passenger transport systems by maintenance workers, which can be carried by the maintenance workers;

• characterized in that the personal mobile terminal comprises:
• a close-range communications unit, which is configured to sense radio signals broadcast by a radio beacon of an on-site check point installed on the passenger transport system;
• and
• a time period information generation unit, which is configured to calculate the time period information of the radio signals broadcast by a corresponding radio beacon and continuously sensed by the close-range communications unit;
• wherein the close-range communications unit is also configured to identify the first identifier of the radio beacon, and the time period information generation unit is also configured to generate time period information including the first identifier and the second identifier of the personal mobile terminal.

A maintenance management terminal, which is used to monitor the maintenance of passenger transport systems by maintenance workers, characterized in that, at a minimum, the maintenance management terminal can establish a wireless connection with a personal mobile terminal carried by a maintenance worker;

• the maintenance management terminal comprises:
• a time period information acquisition unit, which is used to receive time period information from the personal mobile terminal or a radio beacon installed at an on-site check point of the passenger transport system, wherein the time information is the time during which the personal mobile terminal continuously senses the radio signal broadcast by a corresponding radio beacon;
• and
• a compliance determination unit, which is used to determine the compliance of the maintenance operations of the maintenance workers at an on-site check point of the corresponding radio beacon based on the time period information.
