The utility model can be achieved by the following technical measures and pit shaft detection is reached the saving engineering time, reduces work
The purpose of intensity, the one-sidedness for overcoming explanation results and multi-solution, for make above and other purpose of the present utility model, feature and
Advantage can become apparent, it is cited below particularly go out the multifunctional well cassette detection mechanism, and coordinate shown in accompanying drawing, elaborate as
Under.
As shown in figure 1, for the structure chart of multifunctional well cassette detection mechanism of the present utility model.
The multifunctional well cassette detection mechanism is by external multifunctional well cassette detection mechanism 1 and built-in multifunctional well cassette detection mechanism
2 two large divisions constitute.Wherein external multifunctional well cassette detection mechanism 1 include ground based processor 101, external signal projector 102,
External signal receiver 103, transmitting antenna 104, reception antenna 105, detection signal stiffening device 106, detection signal converge dress
Put the composition such as 107, outer control part 108.
Wherein, ground based processor 101：Control detection ripple work, can be connected reading detection information with local computer, may be used also
To be connected with remote computer by wired or wireless data link, run in the case of unattended at the scene, operating personnel
Only need to long-range reception, send the normal operation that control information realizes controller management and guarantee detection means, realize both
Can with local operation can also remote control operation system, the advantage with simple to operate, multi-functional process, convenient manipulation.
In addition, external solar panel self power generation is utilized in its outer surface, in being stored in power supplier 207,
The devices such as all of ground based processor 101, external signal projector 102, external signal receiver 103 can external solar energy
Electroplax, when pit shaft detection is carried out, completes to charge by (wire and wireless) is electrically connected with circuit board, meets multi-functional pit shaft
The electricity needs of detection means.Additionally, testing result direct imaging can be shown to its display for carrying by ground based processor 101
On screen.Testing result is respectively adopted the bright display of distinct methods lamp.

When being detected, excite control ground based processor 101 to start according to preset value by outer control part 108 and report to the police, according to detection feelings
Condition judges detection ripple firing order, starts detection ripple signal enabling third time according to detection field condition and re-emits, i.e. (n+
1) signal detection system, and ripple is detected by external signal projector 102, the transmission signal of transmitting antenna 104, through detection signal
Stiffening device 106 will detect that ripple deviation carries out signal reinforcement, the built-in multi-functional pit shaft detection dress of the triggering control of outer control part 108
The underlying signal receiving device 202 for putting 2 receives signal, completes detection signal communication connection, excites interior control unit 205 to work,
Send by setting order excitation-detection ripple and receive signal, using detection arm 206 and sensor 209 in detection means in pit shaft
Flexible and shift in position, position, state and other setting detection parameters to detecting pit shaft detect that the data for detecting are led to
Cross historical information memory unit 208 to be preserved, outer control part 108 judges whether to complete Detection task again, if completed,
Then detection signal is carried out by detection signal converging device 107 converging reinforcement and coded treatment, will be believed using reception antenna 105
Number received, detection signal is received by external signal receiver 103, being again introduced into ground based processor 101 is carried out data storage
Deposit, show and analyze and process.
If now Detection task can't be completed, outer control part 108 excites control ground based processor 101 according to default
Reported to the police, while carry out the 4th time according to detection field condition control detection ripple signal re-emitting, started higher one-level letter
Number detection ripple detection firing order, that is, respond three-level signal detecting system, while display processing detection data image information.With this
Analogize, carry out up to multilevel signal detection, flow process ibid, until completing setting detection, is processed information, analyzed and is imaged
