Detailed Description
Referring to fig. 1, the control system for laser wavelength switching of the present invention comprises a trigger circuit module, an optical coupling isolation circuit, a 12V dc relay, a display screen, a 532nm control circuit board, a 1470nm control circuit board, a 2100nm control circuit board, and a sensor, wherein the trigger circuit module is connected with the optical coupling isolation circuit, the optical coupling isolation circuit is connected with the 12V dc relay, and the 12V dc relay is respectively connected with the 532nm control circuit board, the 1470nm control circuit board, the 2100nm control circuit board, and the sensor; the trigger circuit module is used for automatically detecting an instruction corresponding to a certain wavelength and generating a certain corresponding trigger electric signal; the optical coupling isolation circuit is used for isolating and coupling the trigger electric signal, and simultaneously isolating and coupling a feedback signal of the corresponding wavelength control circuit and a signal of the isolation coupling sensor; and the 12V direct current relay is used for connecting or disconnecting the communication between the display screen and the wavelength control circuit board.
The trigger circuit module comprises a monostable trigger, a D trigger, an AND gate, an OR gate, a NOR gate and a NOR gate, wherein the output of the monostable trigger is connected with the input of the D trigger, the output of the D trigger is connected with the input of the AND gate, and the output of the AND gate is connected with the inputs of the OR gate and the NOR gate.
The invention discloses a control method of a control system for laser wavelength switching, which comprises the following steps:
step 1): the trigger circuit module detects a certain wavelength switching signal instruction of a certain path of control circuit board and generates a trigger electric signal;
step 2): the triggering electric signal enables the optical coupling isolation circuit to be gated, the 12V direct current relay is closed, meanwhile, the triggering circuit module receives a feedback signal, and the generated triggering signal enables other multiple paths of optical coupling isolation circuits and the 12V direct current relay to be disconnected;
step 3): the display screen and the corresponding wavelength control circuit board start to communicate.
If another wavelength switching signal is detected in the current wavelength mode, the display screen firstly displays an interface exiting the current wavelength mode, waits for several seconds (automatically turns off a power supply in the wavelength mode), the interface prompts to enter a next wavelength operation interface, and meanwhile, the trigger circuit module detects an instruction corresponding to the next wavelength, and the working process of the trigger circuit module is the same as that of the previous wavelength mode.
Because the trigger circuit module has high response speed, in order to avoid that the power supply in the current mode is not automatically cut off because the wavelength switching frequency is too high, the invention designs a waiting interface which exits the current wavelength mode, and the interface disappears after delaying for several seconds, and can be automatically switched into another wavelength mode, thereby ensuring the accurate and efficient wavelength switching.
