Embodiment Construction
[0018] Please see figure 1 , which is a schematic diagram of the emergency stop signal generation system for mechanical equipment provided by the first embodiment of the present invention.
[0019] The emergency stop signal generation system includes a control CPU or an emergency stop information monitoring unit 1 (hereinafter referred to as CPU1 ), an emergency stop signal generation unit 2 , and a first timing unit 3 .
[0020] The CPU1 is a control device of the mechanical equipment, and may be a central controller of the mechanical equipment, or a controller of a certain part of the mechanical equipment. The CPU 1 receives various emergency stop detection information from various positions of the mechanical equipment, and performs emergency stop processing after obtaining certain emergency stop detection information. The emergency stop processing includes two methods. The first processing method is to transmit an emergency stop signal to the upper-level controller through...

The invention discloses an instant stop signal generation system for mechanical equipment. The system comprises a control CPU, a first timing unit and an instant stop signal generation unit, wherein the control CPU is used for receiving various kinds of instant stop detection information at various positions of the mechanical equipment, carrying out instant stop processing after receiving the instant stop detection information and outputting reset signals at time interval S for the reset signals in a normal state. The time to be timed by the first timing unit is set to be an ultimate time T. When the time runs out, the first timing unit generates a CPU failure signal through an output end. A resetting end of the first timing unit is connected with a reset signal output end of the control CPU. The instant stop signal generation unit outputs an instant stop signal after receiving either an instant stop signal output by the control CPU or the CUP failure signal output by the first timing unit. The time interval S for the reset signals is shorter than the ultimate time T. The system can detect whether or not the control CPU operates normally in time and carry out immediate handling.
Description
technical field [0001] The invention relates to mechanical control technology, in particular to an emergency stop signal generation system for mechanical equipment. The invention also provides a construction machine using the emergency stop signal generation system. Background technique [0002] In mechanical equipment such as machine tools or construction machinery, emergency stop signals are generally provided. The signal is sent out in an emergency, and it can control the mechanical equipment to stop running immediately and other emergency treatment. [0003] In mechanical equipment controlled by a microcomputer system, the emergency stop signal is generally sent by the control CPU or the emergency stop information monitoring unit. When abnormal conditions are detected, such as power supply voltage drop, communication signal interruption, etc., an emergency stop signal will be generated to stop the entire control system and perform other emergency treatment to avoid dam...
