referring to fig. 1, the method for wiring a connector with fool-proofing function according to the present invention requires at least two connectors and a PLC controller; the method comprises the following steps:
distinguishing and fool-proofing each connector according to the size, the number of pins and the male and female connectors;
for connectors which cannot be distinguished and prevented through sizes, needle numbers and male and female connectors, two ends of an idle point position of each connector are respectively connected to a public end and a point position of the PLC; the PLC is used for monitoring the connected connectors, and once the connectors are monitored to be inserted wrongly, the PLC immediately links the alarm to give an alarm. In specific implementation, one end of the idle point of the connector can be connected to a 0V or 24V power supply according to actual needs, and the other end of the idle point is connected to the IO point of the PLC controller.
In this embodiment, in order to reduce the number of connection points of the PLC controller, the method further includes:
for connectors which cannot be distinguished and prevented by size, pin number and male and female connectors, according to the group to which the connectors belong, the idle points of the connectors belonging to the same group are connected in series, the idle point of the first connector in each group is connected to a public end, and the idle point of the last connector in each group is connected to the point of the PLC. In other words, in specific implementation, one end of the idle point of the first connector in each group needs to be connected to a 0V or 24V power supply, and the other end of the idle point of the second connector, and so on, until all the connectors are connected in series, the other end of the idle point of the last connector is connected to the IO point of the PLC controller, so that when the connectors are inserted in an error, the IO point of the PLC controller is not powered on, and at this time, the PLC controller sends a signal to an upper computer to alarm.
In this embodiment, in order to facilitate the sharing of the connectors of different groups, the method further requires the use of a plurality of three-pole double-throw switches;
the method for connecting the idle point positions of the connectors belonging to the same group in series, connecting the idle point position of the first connector in each group to a common end, and connecting the idle point position of the last connector in each group to the PLC controller specifically comprises the following steps:
for each connector belonging to the same group, respectively extracting three idle pins of each connector, and respectively recording the three idle pins as a first pin, a second pin and a third pin; connecting a first pin of a first connector with a power supply as required, connecting a second pin and a third pin of the first connector with a first pin of a second connector, connecting a second pin and a third pin of the second connector with a first pin of a third connector, and so on until all the connectors are connected in series, and then connecting the second pin or the third pin of the last connector to a point of the PLC controller; meanwhile, the first pin, the second pin and the third pin of each connector are all connected with one three-pole double-throw switch, and in practical implementation, the use groups of the connectors can be switched through the three-pole double-throw switches; when the three-pole double-throw switch is cut to the third pin of each connector, the three-pole double-throw switch can be used as a group.
In this embodiment, the distinguishing and fool-proofing of the connectors according to the size, the number of pins and the male and female connectors is specifically as follows: when the size or the number of the pins of the connectors are different, distinguishing and fool-proofing are directly carried out according to the size or the number of the pins of each connector; when the size and the number of the pins of the connector are the same and the number of the connectors is 2, keeping the male head and the female head of any connector unchanged, and exchanging the male head and the female head of the other connector.
