Referring to fig. 2, the first operation unit 5 and the second operation unit 6 are industrial control touch screens, which can display the state information received by the control driving unit 4 on the touch screens, the control driving unit 4 communicates with the first operation unit 5 and the second operation unit 6 through a network, when the first transmitter 1 is in a main state, the device state information received by the control driving unit 4 is output to the first operation unit 5 for display, when the second transmitter 2 is in a main state, the device state information received by the control driving unit 4 is output to the second operation unit 6 for display, and meanwhile, the device state information can also be output to the first operation unit 5 for display, so that an operator can conveniently check the specific working states of all devices in the tuning booth 3.

The first transmitter 1 generates a first control signal when in active use, and the second transmitter 2 generates a second control signal when in active use.
In the embodiment of the present application, the control driving unit 4 may be one or more of a PLC, a single chip microcomputer, and a CPU, and the embodiment of the present application is not limited specifically for the equipment specifically used by the control driving unit 4.
Specifically, referring to fig. 2, the switching unit 8 includes a single pole double throw switch and a drive motor. The first fixed end B of the single-pole double-throw switch is connected to a communication main loop of the first transmitter 1, the second fixed end C of the single-pole double-throw switch is connected to a communication main loop of the second transmitter 2, one end A of a knife switch of the single-pole double-throw switch is connected to a communication main loop of the tuning pavilion 3, and an output shaft of the driving motor is fixed with the other end of the knife switch. When the control driving unit 4 receives or generates the first control signal, the control driving unit 4 controls the driving motor to rotate positively, so that the knife switch is abutted against the second stationary end C, and the communication connection between the second transmitter 2 and the tuning booth 3 is realized. When the control driving unit 4 receives or generates the second control signal, the control driving unit 4 controls the driving motor to be electrically reversed, so that the knife switch is abutted against the first stationary end B, and the communication connection between the first transmitter 1 and the tuning booth 3 is realized.
In a single-booth, two-machine switching interlock system, if two transmitters communicate with the tuning booth 3 at the same time, system upsets can be caused. In the embodiment of the application, when the switching unit 8 is a single-pole double-throw switch and a driving motor, the tuning pavilion 3 is only in communication connection with the first transmitter 1 or in communication connection with the second transmitter 2, and the first transmitter 1 and the second transmitter 2 cannot be simultaneously in communication connection with the tuning pavilion 3, so that the probability of system disorder is reduced.
Further, the switching unit 8 may also be a wireless switch, i.e. the switching unit 8 comprises a first wireless switch K1 and a second wireless switch K2. When the control driving unit 4 receives or generates the first control signal, the first wireless switch K1 is opened, the second wireless switch K2 is closed, and communication connection between the second transmitter 2 and the tuning pavilion 3 is realized, and when the control driving unit 4 receives or generates the second control signal, the second wireless switch K2 is opened, and the first wireless switch K1 is closed, and communication connection between the first transmitter 1 and the tuning pavilion 3 is realized.
When the switching unit 8 is a wireless switch, remote control can be performed because no wiring is needed, and maintenance is convenient. Further, the first wireless switch K1 and the second wireless switch K2 may be controlled by a program so as not to be simultaneously closed, thereby enabling the tuning kiosk 3 to be simultaneously connected in communication with only one of the first transmitter 1 and the second transmitter 2.
The switch used in the switching unit 8 in the embodiment of the present application may be a single pole double throw switch or a wireless switch, and the embodiment of the present application is not particularly limited as to the specific type of the wireless switch.
Specifically, referring to fig. 2, the single-booth two-machine switching interlock system further includes a power supply unit 7, and the power supply unit 7 includes a first power supply unit 71 and a second power supply unit 72. The first power supply unit 71 is connected to the first transmitter 1, the control drive unit 4, the first operation unit 5, and the tuner booth 3. When the first transmitter 1 is active, the first power supply unit 71 is supplied with power by the first transmitter 1. Typically, the reason for switching the primary transmitter may be due to a failure of the current transmitter or an operation requiring maintenance and debugging of the current transmitter. For example, when the first transmitter 1 needs to be overhauled or debugged, the operator should control the first transmitter 1 to switch to the second transmitter 2 for use, but in this case, if the first transmitter 1 is still used to supply power to the first power supply unit 71, the power supply may be unstable or even be powered off. Therefore, in order to improve the stability of power supply, the first power supply unit 71 is further connected to the second power supply unit 72, and when the first transmitter 1 is switched to the second transmitter 2 for main use, the second power supply unit 72 should supply power to the first power supply unit 71, that is, when the control driving unit 4 receives or generates the first control signal, the first transmitter 1 stops supplying power to the first power supply unit 71, and the second power supply unit 72 supplies power to the first power supply unit 71.
Further, the switching of the direct power supply relationship between the first transmitter 1 and the second power supply unit 72 and the first power supply unit 71 may be implemented by a contactor switch, or may be implemented by other types of switches.
When the primary switch of the first transmitter 1 to the primary switch of the second transmitter 2 is performed, an operator performs a manual operation on the touch screen of the first operation unit 5, so that the first operation unit 5 outputs a first control signal, and when the control driving unit 4 receives or generates the first control signal, the control driving unit 4 controls the power supply unit, so that the first transmitter 1 stops supplying power to the first power supply unit 71, the second power supply unit 72 supplies power to the first power supply unit 71, and the control driving unit 4 controls the switching unit 8 to disconnect the communication connection between the tuning pavilion 3 and the first transmitter 1, and establish the communication connection between the second transmitter 2 and the tuning pavilion 3, thereby realizing the primary switch of the first transmitter 1 to the primary switch of the second transmitter 2.
The foregoing is only a partial embodiment of the present application, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principles of the present application, and such modifications and adaptations are intended to be comprehended within the scope of the present application.
