Apparatus and method for controlling passenger transportation device

A control system, comprising:

• a central control unit configured to generate external control commands for one or more passenger conveying apparatuses;
• and
• one or more control apparatuses, each of the one or more control apparatuses is adapted to be disposed near or integrated in a respective passenger conveying apparatuses and comprises:
• a processor;
• a memory coupled with the processor;
• and
• a computer program stored on the memory and running on the processor, the running of the computer program causes:
• in response to an internal control command of the one or more control apparatuses or an external control command outside the one or more control apparatuses, determining whether there is a passenger boarding signal in the passenger conveying apparatus within a specified time interval, wherein the internal control command and the external control command comprise commands for starting or stopping the passenger conveying apparatus;
• and
• manipulating the passenger conveying apparatus based on the determining;
• wherein, when the internal control command or the external control command is one for starting the passenger conveying apparatus, the specified time interval is a time interval between a previous stopping of the passenger conveying apparatus and generation of the internal control command or the receipt of the external control command for starting the passenger conveying apparatus;
• upon determining that there is a passenger boarding signal within the specified time interval, sending a message that the passenger conveying apparatus is not to be started.

A method for controlling a passenger conveying apparatus, comprising following steps performed by a control apparatus:

• in response to an internal control command of the control apparatus or an external control command outside the control apparatus, determining whether there is a passenger boarding signal in the passenger conveying apparatus within a specified time interval, wherein the internal control command and the external control command comprise commands for starting or stopping the passenger conveying apparatus;
• and
• manipulating the passenger conveying apparatus based on the determining;
• wherein, when the internal control command or the external control command is one for starting the passenger conveying apparatus, the specified time interval is a time interval between a previous stopping of the passenger conveying apparatus and generation of the internal control command or the receipt of the external control command for starting the passenger conveying apparatus;
• upon determining that there is a passenger boarding signal within the specified time interval, sending a message that the passenger conveying apparatus is not to be started.

A computer-readable storage medium having instructions stored in the computer-readable storage medium, when the instructions are executed by a processor, the processor is caused to execute a method comprising:

• in response to an internal control command of the control apparatus or an external control command outside the control apparatus, determining whether there is a passenger boarding signal in the passenger conveying apparatus within a specified time interval, wherein the internal control command and the external control command comprise commands for starting or stopping the passenger conveying apparatus;
• and
• manipulating the passenger conveying apparatus based on the determining;
• wherein, when the internal control command or the external control command is one for starting the passenger conveying apparatus, the specified time interval is a time interval between a previous stopping of the passenger conveying apparatus and generation of the internal control command or the receipt of the external control command for starting the passenger conveying apparatus;
• upon determining that there is a passenger boarding signal within the specified time interval, sending a message that the passenger conveying apparatus is not to be started.
