Therefore, when the first range finder 21 moves with the bridge 如图 as shown in FIG. 2, the infrared ray emitted by the first emitters 221 of the first range finder 21 will be used by the first marker 22 intermittently masking, so that the corresponding sensor-sensing member 212 has different sensing changes, and synchronously sends the sensing changes to the first detecting signal. Referring to FIG. 4', the first indicator holder 22 has a first body, a plurality of first convex plates 222' and a plurality of first standard plates 223' which are equidistantly protruded from the first body 221 and are substantially square. The first rod is cut in a portion of the first convex-convex plate work, and the first standard plate 223 of each two adjacent 200918438 has the same number of the first protrusions The top plate 222, and the top edge of the second standard plate 223 is higher than the top edge of the first convex plate 222. Referring to FIGS. 2, 3, and 4, when the bridge 13 synchronously drives the first range finder 21 to move and pass the first indicator seat 22, the first convex plate 222 can intermittently block the lowermost row. The infrared rays emitted by the two first emitting members 211 are used to detect the moving distance of the bridge 13. However, if the first convex plate 222 such as 5 hai is used alone for the interpretation of the moving distance, it is easy to be - The range finder 21 is subjected to temporary noise interference, resulting in a temporary data reading loss, causing a difference between the sensing result and the actual moving distance of the bridge 13 'so' the embodiment of the first-convex shape 222 is provided with a plurality of first-standard plates 223, and the height and the visibility of each of the -standard plates 223 are differently changed, respectively, correspondingly shielding or partially shielding the middle row and the uppermost row. The infrared ray emitted by the first launching member 211 enables the first finder 21 to "cut off the different first-standard plates to re-determine the distance moved by the gantry 13 and the correct position of the clamp 16 to avoid The actual moving distance of the bridge 13 and the moving distance of the sensing side The situation of the deviation occurs. The control unit 3 sentences; the terminal device 3 in the control room 15 and receiving the first detection signal 3] 〆 ^, , the birth terminal 31 operation processing After that, it will not show the "a return" of the bridge 13. The distance between the moving distance and the correct position of the clamp 16 is set on the bridge 13 according to the sensing mode of the obscurant. 21 Although the bridge 13 travels, the first The infrared rays emitted by a launch of 200918438 2U will be affected by the first convex plates 222 and the first standard plates 223, so that the first range finder 21 has different sensing changes, and the basin will be salty. The first test signal is transmitted to the terminal unit 31. With the arrangement of the first range finder 21 and the first indicator holder 22, when the bridge 13 moves with the clamp 16, the first range finder 21 will be synchronized with the bridge 13 to make the first - the distance measuring device 21 passes through the first and second display blocks U, and the first sensing elements 212 have different sensing changes according to the moving distance: and change the first detecting signal After being transmitted to the terminal device 31', the terminal device 31 performs the arithmetic processing, and (4) the correct position of the jig 16 is not provided, so that the jig 16 operated by the crane operator can be quickly placed in position, thereby improving the overall efficiency. Referring to Figures 5 and 6, a second preferred embodiment of the positioning system for a crown-lifting device of the present invention is substantially the same as the first preferred embodiment, i.e., the same is that the crane device 11 includes - Bridge, - control room 15' and - clamp 16' The positioning system comprises - a first distance measuring unit 2, and a control unit 3, and the difference is that: the crane device U is provided with two phases The spaced track 12 (only the - track is shown in Fig. 5), the control room 15 is movable = set on the bridge 13, and the dislocation 16 is moved with the control room, as for The second clamping unit 4 further includes a second distance measuring unit 4, and the second distance measuring unit 4 includes a second bracket 40 that moves synchronously with the operating room 15 and is also substantially inverted U-shaped, and is fixed to the second a second range finder 41 on the bracket 4 and capable of emitting a second read signal, and a second indicator seat 42 disposed on the bridge 13 for the second test 10 200918438 heart 41 (4), the terminal η The first and second detection signals can also be received and the results displayed. The design of the μ / the first distance measuring 41 is the same as that of the first range finder 21, the second range finder 4 and the dead zone / 琢", and the second emission is arranged at an outer line on the same side of the second bracket 4 a piece 411 'and corresponding to each of the second transmitting members 411 and also spaced apart from the six second sensing members 412 ′ that are placed on the other side of the second bracket 40 of the β-Hui and the second bracket 4 is All of the second inducing members 412 are located on the opposite side of the second indicating seat 42 and all the second inducing members 412 are located on opposite sides of the second indicating seat 42 . When the second finder 4 is powered on, and there is no shielding between the 々 411 and the corresponding second sensing component 4i2, the second sensing component 412 can sense the corresponding second. After the infrared light emitted by the transmitting member 411 is less, the net is less than the net. Conversely, once the infrared light emitted by any of the second emitting members 411 is shielded by the foreign object, the second sensing material 412 corresponding thereto will be Inductive state. Therefore, when the second range finder 4 i moves with the control room 15, the second (four) 41 of the second The infrared ray emitted by the transmitting member 421 will be intermittently shielded by the second indicating seat 42 so that the corresponding second sensing members 4 丨 2 have different sensing changes, and the same is detected: the second detecting signal 々 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二a second convex plate 422, and a plurality of second standard plates 423', wherein the second standard plate 423 is protruded from a portion of the 200918438 convex plate 422, and each second adjacent second standard plate 423: = the same number of the second protrusions ... 22, and the top edge of the second ^ = 423 is higher than the top edge of the second convex plate 422. - - ranging unit 2 and The arrangement of the two measuring distances, when the first Γ Γ 13 is moved longitudinally relative to the tracks 12, the infrared rays emitted by the L' member 211 are subjected to the first convex plates 22, the Μ筮 4®, the official, The convexity of the 板 plate 222 is affected by the dynamic distance, and the first range finder 21 will have different sensing changes as the shifting is performed, and the test signal is transmitted to the The end machine 31, when the crane device: the younger; the opposite side of the bridge 13 birch to the mobile. The mechanic to 15 "" 勹 mobile day guard, the second launching member 411 is launched: the second one In contrast to the second standard board::: she is different in distance and the younger one has a detection signal transmitted to the terminal 31' and then calculates the virtual position via the terminal 31. After the ten different treatment, the display (four) fixture 16 is correct. In addition, the crane is equipped with a 彳 里 里 第 訾浐 訾浐 訾浐 訾浐 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该u: In the obtained::, each car device 11 is moved to the St signal by mobile, and the terminal 31 performs wireless transmission routing (not shown), and then uses the Ethernet to control (10) to transfer to the map. In order to achieve remote control and management. In summary, the present invention is applicable to the first and second range finder 21, 41 of the crane and the first utilization of the When the bridge 13 and the clamp 16 are moved, the first and second ranging distances 12 200918438 191 and 41 can be synchronously moved, and the first and second indicator seats 22 and 23 are used to enable the second and second sensing members 212. 412 will move with the distance: length, different inductive changes, and then change the same to the first, second, and second messages (4) to the terminal device 3 after the terminal machine η operation processing, then display The bridge n & + mesh, ^ and the correct position of the clamp 16, not only make the crane known as the shell I 4 operation sentence sentence · 4 · β 1 / ', Wei, ~ clip eight 16 can be quickly put in place, shortening the operation time = enough to eliminate the labor cost of the ground support personnel, and the overall efficiency of the work with the lift #, can indeed achieve the purpose of the present invention.
