Terminal computer is connected with printer, is used to print examining report.
In this embodiment, adopt the device of monitoring asphalt penetration test to carry out the method that the pitch label detects, flow process is as shown in Figure 2.This method originates in step 201.In step 202, when receiving sample, the staff on rfid interrogator through receiving appearance end computing machine writes sample to the RFID label essential information; And the RFID label that will have sample message sticks on the sample, as the unique identification to this sample.
In step 203, before going to asphalt penetration test, sample is carried out heat, make sample temperature reach the requirement of making the test test specimen.
In step 204, before making test specimen, open camera head and make a video recording; The rfid interrogator that utilizes terminal computer to connect reads the information of RFID label; And through bar code information of the automatic generation of the data handling system on the terminal computer; This bar code information is identical with the RFID label information that reads; Print through printer again, form the waterproof bar code, paste on the sample-containing dish; Then the sample after the heat is poured in the sample-containing dish that is pasted with the waterproof bar code, be made into the test test specimen.
In step 205, after waiting to test test specimen and at room temperature preserving 1～1.5 hour, health is carried out in the water bath with thermostatic control (the water bath with thermostatic control temperature in this embodiment is got 25 ℃) that sample-containing dish is put under the test temperature.
In step 206, test specimen health at least 1 hour is opened bitumen needle forcemeter then and (is made up of water-bath, display, electronic digital display scale, status indicator lamp and keyboard; Adopt rack structure up and down; Regulate by gear, and be furnished with cold light source illumination, reflective mirror, digital temperature sensor), when the water-bath on the bitumen needle forcemeter (bath temperature in this embodiment is got 25 ℃) when reaching test temperature; Penetration test is carried out in the water-bath that sample-containing dish is put on the bitumen needle forcemeter; Simultaneously, camera head is taken entire test, and video information is uploaded to monitoring computers.
In step 207; After the off-test; Bitumen needle forcemeter uploads to detected pitch label in the terminal computer; Data handling system in the terminal computer compares the critical field of the pitch label that carries in this pitch label and the data handling system, and with test before pitch label in the RFID label information that reads compare, if be not inconsistent then system alarm prompting.The critical field of the pitch label that carries in the data handling system is as shown in table 1:
Table 1 is the standard span of pitch label
| The pitch label | Critical field |
| 80 | 70～90 |
| 90 | 80～100 |
| 100 | 90～110 |
As the label of the asphalt sample of sending here is 80, and after measuring through bitumen needle forcemeter, the pitch pen. result who is generated by data handling system is 87, and then the table of comparisons 1 can be known, this pitch label should be 80, and is identical with the RFID label information, prove that detection is qualified; If the pitch pen. result who is generated by data handling system is 97, then the table of comparisons 1 can be known, this pitch label should be 90, is not inconsistent with the RFID label information, proves that detection is defective, need report to the police.
In step 208, detect qualified test specimen and will print examining report.
Though more than described embodiment of the present invention, the one skilled in the art should be appreciated that these only illustrate, and can make numerous variations or modification to these embodiments, and not deviate from principle of the present invention and essence.Scope of the present invention is only limited appended claims.
