摘要:
A method for interacting master and slave information in real time, comprising: collecting, by N slave control MCUs, sensor signals of sensors respectively connected thereto; feeding back, by the N slave control MCUs, the sensor signals to a master control MCU via a signal transfer panel; and when the sensor signals satisfy a pre-set condition, giving, by the master control MCU, a control instruction to a corresponding slave control MCU according to the pre-set condition, wherein both the sensor signals and the control instruction are transmitted between the master control MCU and the slave control MCUs via the signal transfer panel in an SP signal manner. Also disclosed is a system for interacting master and slave information in real time. The method for interacting master and slave information in real time can reduce the redundant information interaction and improve the communication efficiency.
摘要:
Disclosed is a system for transmitting a position switch status signal. The system comprises a signal output unit, a first converting apparatus, a second converting apparatus, and a control unit. Status signals of position switches are outputted by the signal output unit, parallel status signals are converted into parallel first current signals by using the first converting apparatus, currents in the first current signals are summated to obtain a second current signal, and digital status signals of the position switches are restored by using the second converting apparatus and the control unit. Also disclosed is a method for transmitting a position switch status signal. In the present invention, because status signals of transmission position switches of a sequential circuit are not used, there is no effect of the sequential circuit, so that a main control module can quickly and accurately acquire status signals of the position switches; in addition, a second current signal can be transmitted through a minimum of one cable, and therefore, the diameter of a cable bunch between the main control module and a functional module can be shortened to the minimum.
