The instruction control unit of magnetic ejector 3 can adopt command source formula or other modes, audible segment has adopted commercially available super loudness alarm, penetrate 30 millimeters wall thickness steel plates through testing its sound, still very clear loud in the pipeline outside, no matter be all can use in that pipeline is inside and outside, especially at pipe interior, this is the simplest a kind of export-oriented information transferring method.
That the programmable controller in house software has been finished is anti-interference, anti-shake, judgement etc. is after early stage, signal was handled, and signals to software timer, by modification and the demonstration of software timer program deadline.In program, also be provided with the upper and lower protection.
The signal that the instruction transmitter sends, this signal sees through steel pipe walls, and the magnetic receiving sensor that is installed on the crawl device receives, and inputs to the PLC program, through the special-purpose timer module of PLC inside, the exposure time of control X-ray production apparatus.
The concrete operation method that exposure time is regulated:
Do not start or in pipeline, shut down resting state in start; use command source to send and surpassed for 10 seconds signal duration; crawl device will enter the adjusting time state; signal sound will stop; send signal with command source again; to hear that sound pipes; 1 second cycle; at this moment; the endurance (number of times that namely pipes) that command source is sent signal is exactly the time of exposure next time; the regulation range of time is 0-300 second; when exposure time of needs (number of times had both piped) when reaching predetermined value, with the command source signal at stop, crawl device will withdraw from the timing program automatically and begins to give the correct time after 10 seconds; the program of giving the correct time is used the sound of per second 1 time and is represented present timing, gives the correct time can enter the not starting state of starting shooting after finishing.Set the exposure time upper limit 300 seconds; it is the consideration for the protection X-ray production apparatus; prevent that the exposure time is long and damage the X-ray machine X part; and the exposure time of actual pipeline generally was less than 300 seconds; in adjusting; in case numerical value surpasses the upper limit or is lower than lower limit, data can be fixed to the upper limit or lower limit automatically.
After the entry time adjustment state, if do not carry out any operation, also will withdraw from this state automatically after 10 seconds, and begin to give the correct time, and can make you understand present exposure time numerical value at any time.
This example has realized non-contact type adjusting timer time value through test of many times, can satisfy the needs between on-the-spot remote control timing; The number of times that can be rung by sound is at any time known current phototiming value; Easy to adjust, efficient is high, and prolonged the working life of equipment; For detecting, changed wall thickness pipeline provides convenience.
