Step 202), according to step 201) the temperature sensing data T1 that obtains and operating state data S1 judges whether slot light collection apparatus (4) is in the duty that the settled date follows the tracks of, if slot light collection apparatus (4) is in the settled date and follows the tracks of duty and temperature higher than given threshold value, then be in abnormal operating state, perform next step, otherwise, get back to step 201), continue monitor procedure;
Step 203), judge whether described slot-type optical collector controller (3) is in automatic treatment state, as being automatic treatment state, described slot-type optical collector controller (3) sends control command, parts in drived control slot light collection apparatus (4), make the thermal-collecting tube in slot light collection apparatus (4) depart from focus point, transmission warning simultaneously and process information are to described top control module (1); As being manual handle state, then the settled date suspending slot light collection apparatus (4) follows the tracks of, and reports to the police to described top control module (1), waits for that attendant carries out manual maintenance.
