Massage bathtub automatic control system and method for controlling the same

A method of automatically controlling a massage bathtub connecting a plurality of attaching devices, the method comprising:

• providing a digital control unit and a control panel comprising a visual-displaying unit and a master control device connected to an input device;
• turning on a power switch on the control panel to initialize the control panel;
• showing a function menu on the visual-displaying unit, the function menu comprising a plurality of set items each corresponding to an operation of the attaching devices in single or combination;
• selecting one of the set item by using the input device to generate a control command via the master control device;
• and
• the digital control unit controlling an operation of one of the attaching devices based on the control command, and then returning the operational result of the attaching device to the control panel.

A method of automatically controlling an automatic control system for use in a massage bathtub connecting a plurality of attaching devices, the method comprising:

• providing a digital control unit configuring a plurality of timers to detect a plurality of control panel simultaneously, when the system operates under a normal mode;
• when the digital control unit receives a control command from one of the control panels via a first interface bus, one of the timers starts to count from a starting value until a predetermined upper threshold of a time period;
• if the digital control unit receives other following control commands from the same control panel during the process of counting, the timer returns to the starting value and restarts to count from the starting value;
• if the digital control unit does not receive other following control commands from the same control panel during the process of counting, the timer continues counting to obtain a time value;
• if the digital control unit determines that a program operation of the control panel fails due to the time value in excess of the predetermined upper threshold of the time period, the control panel enters an emergency power-off mode which comprises automatic shutdown of the attaching device, power-off the control panel and restarting the control panel;
• and
• if the digital control unit determines the time value does not exceed the predetermined upper threshold of the time period, the timer continues counting.
