B, utilize probe 2 to detect each test point temperature, utilize controller 3 records and storage testing result at warm-up phase;
C, the detected temperatures of each probe 2 is carried out digital sample every a sampling period, sampling period is 0.1s, controller 3 compares the detected temperatures of sampled data and this probe 2 warm-up phases, judge according to comparative result whether this probe 2 contacts the tin corrugated, if the comparative result difference is bigger, then be judged as this probe 2 and contacted the tin corrugated, pick up counting, be judged as this probe 2 if comparative result does not have significant difference and also do not contact the tin corrugated, continue to detect sampling; After picking up counting, continuation is sampled to the detected temperatures of each probe 2, and the detected temperatures of sampled data and this probe 2 warm-up phases compared, judge according to comparative result whether this probe 2 has left the tin corrugated, if the comparative result difference is bigger, then be judged as this probe 2 and also contact the tin corrugated, continue timing, be judged as this probe 2 if comparative result does not have significant difference and left the tin corrugated, finish timing; The timing result data then are the time on probe 2 contact tin corrugateds, utilize controller 3 with this time data record and storage, and time data shows by display screen 4 simultaneously;
D, adopt multiple spot relatively to carry out the depth of parallelism analysis of tin corrugated the time data on each probe 2 contact tin corrugateds, judge the shape on tin corrugated by comparing result.
Shown in the face table 1, if the tin corrugated of detecting is a rectangle, arrange because the right and left probe 2 is the types that are in line as follows, all probes 2 are timing simultaneously so, also are to stop timing simultaneously, so the time of the contact tin face of the corresponding probe 2 of the right and left equates.
| Probe | A | B | C | D |
| Right | 51 | 51 | 51 | 51 |
| A left side | 51 | 51 | 51 | 51 |
Table 1, each probe are spent the time on rectangle tin corrugated
Shown in the face table 2, if detection tin face is not a rectangle, for example be oval as follows, middle probe 2 is contact tin corrugated earlier, contact behind two ends, the left and right sides probe 2, and probe 2 was crossed tin face time weak point in the middle of then the probe 2 at two ends, the left and right sides was crossed tin face time ratio.
| Probe | A | B | C | D |
| Right | 20 | 36 | 46 | 51 |
| A left side | 20 | 36 | 46 | 51 |
Table 2, each probe are spent the time on non-rectangle tin corrugated
Draw thus: if the time of all probe 2 contact tin faces is equal, then judge the rectangle that is shaped as on tin corrugated,, judge that then being shaped as of tin corrugated is not rectangle if the time of all probes 2 contact tin faces is unequal.
This method adopts the tin corrugated depth of parallelism to detect, adopted the digital collection detection method again, more convenient to operate, no potential safety hazard, accuracy of detection also obviously improves, and to detect overall process all be to finish automatically, and Maintenance free personnel participate in, also various detection data can be preserved for a long time, be convenient to analyzing and processing.See shown in Fig. 3～5, the invention also discloses tin furnace parameters detection system, it includes detects tool 1, detecting tool 1 can move along the transmission track 10 of tin stove, the bottom of detecting tool 1 is provided with the probe 2 of each test point temperature of a plurality of detections, handles and store the controller 3 that probe 2 detects data immediately, and a plurality of probes 2 adopt the linear pattern mode to arrange, and are divided into left and right sides two parts of symmetry, be distributed in the both sides of transmission track 10, can adopt multiple spot relatively to carry out the depth of parallelism analysis of tin corrugated.The bottom of detecting tool 1 offers groove 11, and probe 2 vertically is arranged in the groove 11, and the contact of probe 2 and does not expose the bottom surface of detecting tool 1 down, and is highly concordant with substrate tin sticky.During detection, will detect earlier on the transmission track 10 that tool 1 is placed on normal operation; Detect the parameter of each test point, and by controller 3 records and storage; After detecting end, take out detection tool 1 at transmission track 10 other ends; Last observed result is with each data demonstration as a result and analysis.Controller 3 is provided with the LCDs 4 that is used for storage data on the display controller 3, and LCDs 4 is connected with controller 3 signals.Controller 3 is circumscribed with upper computer system 5, is used for the detection data information on the controller 3 is carried out Treatment Analysis.Controller 3 will detect data communication by RS232 interface or USB interface and give upper computer system 5.
