Description of drawings
Fig. 1 is structural principle block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this Laser Control System comprises laser power detection system and the user interface and the security alerting system that are attached thereto, also comprises the pressure control system, power supply and power TT﹠C system and the temperature control system that are connected with user interface and security alerting system respectively.
Pressure control system is made of thermocouples tube and capacitance diaphragm absolute pressure transducer, can realize the pressure of different range is detected.
The high power CO that the utility model relates to
2Laser, the pressure of working gas have higher stability and repeatability to the testing requirement of this section air pressure roughly between 6 kPas to 12 kPas.Along with the laser long time running, operating air pressure can change, and at this moment needs to change continuously working gas, and gas pressure roughly changes at positive and negative tens of handkerchiefs, requires in this segment limit air pressure to be detected, and the maintenance work stable gas pressure is constant.In addition, because laser is a vacuum cavity with complicated shape multi-sealing surface, if small gas leak phenomenon occurs, its detection method is that cavity is continued to vacuumize, when vacuum degree when several handkerchiefs reach constant in the tens handkerchief scopes, examine air pressure change, leak source is shown in inspection, therefore, require and to be detected more accurately for higher this section air pressure range of vacuum degree.For this reason, two kinds of transducers in the utility model employing pressure control system detect the pressure of different range, for the air pressure below 400 handkerchiefs, detected by thermocouples tube, when air pressure is then finished detection by the capacitance diaphragm absolute pressure transducer during greater than 400 handkerchief, then the signal input user interface and the security alerting system that thermocouples tube and capacitance diaphragm pressure transmitter are transmitted, after carrying out linear fit according to the parameter characteristic of transducer, judge output control blower fans running and fill the significant digits signal of exhaust process by various computings again, thereby reach accurate detection laser operating air pressure and finish the function of the various controls relevant with air pressure.
Detection control for laser power supply, it mainly is the size of control voltage and current, and according to given power adjustments discharging current to needed value, this just need to guarantee on voltage, the normal basis of size of current scope, the adjusting silicon controlled angle of flow reaches required current value.In order to realize the real-time detection of laser power and don't to affect Laser output, the utility model adopts power supply and power TT﹠C system, realize the signal that power supply and power TT﹠C system and interface thereof transmit is processed by the software programming to programmable controller, and with the power signal digitlization that records, show, make whole system form a negative feedback loop, by the relevant electrical quantity of this power feedback signal regulating and controlling laser, reach and keep the purpose that Real Time Monitoring is stablized and realized to laser power, to various abnormal conditions, this system can provide various warnings or interrupt processing by user interface and security alerting system simultaneously.
The stable operation of laser also depends on the each several part temperature and keeps stable, thereby must implement effectively control to the each several part temperature, temperature control system in the utility model, the temperature that need to control each several part detects, and with in input user interface and the security alerting system in its set of signals, by program each several part temperature (temperature of upstream temperature, downstream temperature, two chamber mirrors, the temperature of normal-temperature water and the temperature of power unit) is implemented regulating and controlling, and come the practical adjustments temperature by its output signal, to reach the scope of permission.
