Because the present invention is provided with central testing circuit and local testing circuit, transmission of digital signals can be carried out by power line, avoid and use traditional communication module to communicate with communication protocol, provide cost savings and resource.
The Frame of centre panel comprises 1 initial spy, 4 address bits, 6 data bits, 1 check bit and two stopping bits.Each gating circuit distributes an address, owing to only having 4 address bits, therefore can control at most 15 doors, and one of them address is as broadcast address, and as 11 11 as broadcast address, other address is used for each distribution.The Frame of gating circuit comprises: 1 initial bits, 4 address bits, 6 data bits, 1 check bit and two stopping bits, wherein, 4 address bits only employ an address, namely distribute the address come.Above-mentioned frame structure is just illustrated, and owing to not needing to use existing communication module and communication protocol, so can use the arbitrary frame structure oneself needed, quantity and the content of the door that can control as required are selected.When centre panel needs to make each gating circuit perform identical instruction, broadcast address is used to send instruction, AND operation is carried out by turn in address in the Frame that each gating circuit makes the next address of distribution and centre panel send, result as AND operation is mated with the allocation address of oneself, takes out the information of the data bit in Frame to perform corresponding order.When centre panel needs to send instruction to certain gating circuit separately, the address bit of Frame is the address of this gating circuit.When needs opening track door, the address of the Frame that centre panel sends is broadcast address, and the data bit of this Frame is the information that the motor of each gate circuit is rotated forward.After each gating circuit receives this broadcast message, motor is rotated forward, thus opening track door, when Rail Door closed by needs, the address of the Frame that centre panel sends is broadcast address, and this broadcast data frame data bit is the information of the motor reversal making each gate circuit.After each gating circuit receives this Frame, make motor reversal, thus closedown Rail Door, when each door control unit receives the information of closing Rail Door, if after the signal that ANR and/or ANL receiving this cell gate connects simultaneously, motor is rotated forward, and driven by motor two Rail Door moves to both sides, makes two fan doors at least keep the distance of a safety.If now, ANR and/or ANL disconnects, and stepper motor is temporarily quit work, after waiting delay safety time, then continues to provide the signal that stepper motor is reversed.Control specifically controls: when needs opening track door, and centre panel utilizes its broadcast address to send the command signal of " unlatching ", after each gating circuit receives the command signal of " unlatching ", and door controller DCU
lthere is provided the pulse signal of rotating forward to stepper motor driver through photoelectrical coupler PE2, motor rotates forward, and it drives two fan Rail Doors to move to both sides, and at this moment Hall is opened KR1, KR2, KL1 and KL2 and all disconnected; When Rail Door is opened completely, namely first moves to the leftmost side, and second moves to the rightmost side.Magnet steel on first is aimed at Hall switch KL1, and Hall switch KL1 connects, and the second magnet steel on second is aimed at Hall switch KR2, and Hall switch KR2 connects, DCU
lafter receiving this signal, provide signal to photoisolator PE2, stepper motor is quit work.When user needs to close Rail Door, centre panel utilizes its broadcast address to send the command signal of " closedown ", after each gating circuit receives the command signal of " closedown ", and DCU
lthere is provided the pulse signal of reversion to stepper motor driver through photoelectrical coupler PE2, motor reversal, it drives two Rail Doors to move to centre, and be first when fully closed and move to the rightmost side, second moves to the leftmost side.The first magnet steel on first is aimed at the first Hall switch KR1, and Hall switch KR1 connects, and the second magnet steel on second is aimed at Hall switch KL2, and Hall switch KL2 connects.DCU
lafter receiving these two signals, provide signal to photoisolator PE2, stepper motor is quit work.In the process that Rail Door is closed, if DCU
lafter receiving the signal of ANR and/or ANL connection, provide the pulse signal of rotating forward through photoelectrical coupler PE2 to stepper motor driver, motor rotates forward, it drives two Rail Doors to move to both sides, make two fan doors at least keep the distance of a safety, so, prevent Rail Door people to be crushed.If now, ANR and/or ANL disconnects, and processor provides signal wouldn't to photoisolator PE2, stepper motor is temporarily quit work, after waiting delay safety time, then continues to provide the signal that stepper motor is reversed to close Rail Door.
The above is only done detailed description to embodiments of the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
