Operating table having emergency mode

Control equipment for an operating table, the control equipment comprising:

• at least one pair of relays, respective output terminals of two relays in each of the at least one pair of relays being receptively connected to both ends of at least one motor included in the operating table, respective normally-closed terminals of the two relays being connected to a DC power source;
• a driver which is connected between ground and the respective normally-opened terminal of each relay of the at least one pair of relays, so as to work upon receiving a drive signal so that a normally-opened terminal of each relay of the at least one pair of relays is connected with the ground;
• a microcontrol unit which is used to output the drive signal to the driver in the case of being not disabled and to output a control signal to a control input end of the corresponding relay of the at least one pair of relays when a specified key on a keyboard is pressed down;
• and
• a control module embodied by hardware for disabling the microcontrol unit in response to detection that a key of the keyboard indicating the emergency mode is pressed down, outputting the drive signal to the driver, and making the control input end of each relay of the at least one pair of relays connected to the corresponding key of the keyboard.
