In order to be compatible with local startup and shutdown and remote startup and shutdown to AGV, the application relates to an AGV startup and shutdown control circuit.
Referring to FIG. 1, the AGV switch control circuit includes a power supply 10, a local switch S1, a remote switch S2, and a contactor 20.
The local switch S1 comprises a local normally closed contact and a parallel local normally open contact; the local normally closed contact has two ends 11 and 12 and the local normally open contact has two ends 13 and 14.
The local normally open switch and the local normally closed switch are ganged, i.e., when the local normally open switch is open, the local normally closed switch is closed, and when the local normally open contact is closed, the local normally closed contact is open.
The local switch S1 may be a key switch or a push button switch.
The remote switch S2 comprises a remote normally closed contact and a parallel remote normally open contact; the remote normally closed contact has two ends 21 and 22 and the remote normally open contact has two ends 23 and 24.
The remote normally closed contact and the remote normally open contact are linked, i.e., when the remote normally closed contact is open, the remote normally open contact is closed, and when the remote normally closed contact is closed, the remote normally open contact is open.
The remote switch S2 is a digital control switch.
The remote normally closed contact and the local normally open contact are connected in series to form a first branch circuit; and the remote normally-open contact and the local normally-closed contact are connected in series to form a second branch.
The power supply 10 supplies power to the contactor 20 through the first branch or the second branch.
When contactor 20 is powered on, the AGV powers on, and when contactor K2 is powered off, the AGV shuts down. Specifically, normally open contact K1 that contactor 20 corresponds is connected in the power supply line to the AGV power supply start, and when contactor 20 got the electricity, corresponding normally open contact K1 was closed, and the AGV power supply is started (promptly, all useful electrical parts all went up in the AGV), and when contactor 20 lost the electricity, corresponding normally open contact K1 disconnection, the AGV loses the electricity and shuts down.
In the application, the remote switch S2 and the local switch S1 can be independently controlled and are not interfered with each other, so that the startup and shutdown flexibility of the AGV is improved.
The specific type of the AGV startup and shutdown is described as follows.
(1) Local on-off machine
When the local switch S1 is a key switch, the key switch is turned, the local normally open contact is closed, that is, the terminals 13 and 14 are connected, the terminals 11 and 12 are disconnected, the first branch is closed, the second branch is disconnected, and the power supply 10 supplies power to the contactor 20 through the first branch, so that the contactor 20 is powered on, and the AGV is started;
when the key switch is turned again, the local normally open contact is opened, that is, the end 13 and the end 14 are opened, and the end 11 and the end 12 are closed, at this time, the first branch and the second branch are both opened, the power supply 10 cannot supply power to the contactor 20, and therefore, the AGV is shut down because of no power supply.
(2) Remote on-off machine
When the remote switch S2 receives the start signal, the remote normally open contact is closed, that is, the terminals 23 and 24 are connected, and the terminals 21 and 22 are disconnected, at this time, the first branch is disconnected, and the second branch is closed, and the power supply 10 supplies power to the contactor 20 through the second branch, so that the contactor 20 is powered on, and the AGV starts up;
when the remote switch S2 receives the shutdown signal, the remote normally open contact is opened, that is, the terminals 23 and 24 are opened, and the terminals 21 and 22 are closed, at this time, the first branch and the second branch are both opened, the power supply 10 cannot supply power to the contactor 20, and therefore, the AGV is shut down because of no power supply.
Referring to the dashed box portion of fig. 1, in the present application, the power on/off signal received by the remote switch S2 is obtained as follows.
The remote control device 30 can issue the power on/off signal remotely, for example, to the wireless I/O module 40 through the WIFI network.
The relay 50 is connected to the wireless I/O module 40 for receiving the on/off signal.
The power on/off signal here includes a power on signal and a power off signal.
When the relay 50 receives the starting signal, the relay 50 is powered; when the relay 50 receives the shutdown signal, the relay 50 is de-energized.
In the present application, the remote switch S2 corresponds to a contact of the relay 50, the remote normally closed contact is a normally closed contact of the relay 50, and the remote normally open contact corresponds to a normally open contact of the relay 50.
That is, when the remote control device 30 issues the power-on signal wirelessly and remotely, the relay 50 is powered on, and the remote normally open contacts are closed, that is, the terminals 23 and 24 are closed and the terminals 21 and 22 are opened.
When the remote control device 30 wirelessly issues a shutdown signal, the relay 50 is de-energized, and the remote normally open contacts are opened, i.e., the terminals 23 and 24 are opened and the terminals 21 and 22 are closed.
To indicate whether the power supply 10 is capable of supplying power to the contactor 20 by local or remote power-on modes for the convenience of the operator, in this application, a local power-on/off indication branch 60 and a remote power-on/off indication branch 70 are provided, see fig. 2.
For example, the local power on/off indication branch 60 and the remote power on/off indication branch 70 have the same structure, and both include serially connected indicator lights and/or buzzers and/or voice announcers.
Referring to fig. 2, in the present application, the indication lamps in the local power on/off indication branch 60 and the remote power on/off indication branch 70 are exemplified as LED lamps.
The local power on/off indication branch 60 is connected in series with the first branch, and the remote power on/off indication branch 70 is connected in series with the second branch.
When the power supply 10 is powered on locally, the contactor 20 is powered through the first branch, and thus the indicator LED1 in the local power on/off indication branch 60 is illuminated.
During local shutdown, both the first branch and the second branch are open, so there is no current in indicator LED1 in local shutdown indicator branch 60, and therefore indicator LED1 is not lit.
When the power supply 10 is powered on remotely, the power supply supplies power to the contactor 20 through the second branch, and therefore, the indicator LED2 in the remote power on/off indication branch 70 is lit.
During remote power-off, both the first branch and the second branch are open, so there is no current in indicator LED2 in remote power-off indicator branch 70, and therefore indicator LED2 is not lit.
The indicator light LED1 in the local power on/off indication branch 60 and the indicator light LED2 in the remote power on/off indication branch 70 may be differently colored to facilitate distinguishing between local power on and remote power on.
Also to indicate the power-up condition of the AGV to avoid the AGV not being powered on due to the fault of the normally open switch K1 of the contactor 20 when the power supply 10 is supplying power to the contactor 20 through the first branch or the second branch, see fig. 2, the present application relates to the operation indicating branch 80.
The operation indication branch 80 may include an indicator light and/or a buzzer and/or a voice announcer, etc. connected in series.
In this application, the indication lamp in the operation indication branch 80 is taken as an LED lamp for example.
The operation indicating branch 80 is connected in series with the normally open switch K1 of the contactor 20, and when the normally open switch K1 of the contactor 20 is closed, the operation indicating branch 80 indicates that the AGV is operating at start-up.
When the power supply is turned on locally, the power supply 10 supplies power to the contactor 20 through the first branch circuit, so that the normally open switch K1 of the contactor 20 is closed, the AGV is powered on to work, and the indicator light LED3 in the work indication branch circuit 80 is turned on at this moment.
When the local shutdown is performed, the first branch and the second branch are both disconnected, so that the contactor 20 loses power, the normally open switch K1 of the contactor 20 is disconnected, the AGV loses power and stops, and at the moment, no current flows in the indicator light LED3 in the work indication branch 80, so that the indicator light LED3 is not bright.
When the AGV is remotely started, the power supply 10 supplies power to the contactor 20 through the second branch, so that the normally open switch K1 of the contactor 20 is closed, the AGV is electrified to work, and the indicator light LED3 in the work indication branch 80 is bright at the moment.
When the remote shutdown is performed, the first branch circuit and the second branch circuit are both disconnected, so that the contactor 20 loses power, the normally-open switch K1 of the contactor 20 is disconnected, the AGV loses power and stops, and at the moment, no current flows in the indicator light LED3 in the work indication branch circuit 80, so that the indicator light LED3 is not bright.
The AGV startup and shutdown control circuit provided by the application can be compatible with AGV remote startup and shutdown and local startup and shutdown, and the local startup and shutdown and the remote startup and shutdown are independently controlled and do not interfere with each other; remote switch machine is convenient to AGV's unified centralized management, and local switch machine is convenient to AGV's control on the spot, realizes AGV's multiple nimble control, and remote control avoids the workman to carry out the switch machine to AGV in the factory, when saving the amount of labour, promotes AGV conveying efficiency.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
