Here, with the detected portion of 14 cooresponding the 1st～the 4th top mounting rod 2a～2d of detecting sensor portion, be separately installed with action movie (upper board) 5a, 6a, 7a and 8a.Relative therewith, with the detected portion of 14 cooresponding the 1st～the 4th bottom mounting rod 3a～3d of detecting sensor portion on, lower panel then is not installed fully.
Otherwise, with in that corresponding to the detected portion of the 1st of detecting sensor portion 15～the 4th top mounting rod 2a～2d upper board not to be installed fully relative, on detected portion, then be separately installed with action movie (lower panel) 9a, 10a, 11a and 12a corresponding to the 1st of detecting sensor 15～the 4th bottom mounting rod 3a～3d.
Promptly, near top layer flooring above the lifting hoistway 1 everything position 18U～21U, dispose action movie (upper board) 5a, 6a, 7a and 8a corresponding to detecting sensor portion 14, and below near the bottom flooring all operating position 18D～21D, then dispose action movie (lower panel) 9a, 10a, 11a and 12a corresponding to detecting sensor portion 15.
Again, be in the action movie (plate) 5～12 on the operating position of symmetrical position relation, be arranged to replenish mutually the configuration structure of the configuration of action movie (plate) 5～12, that is, be arranged to complementary configuration structure.For example:, in 4 detected portion of the 1st mounting rod 2a, only dispose action movie (upper board) 5a in detected portion corresponding to detecting sensor portion 14 at the 1st top operating position 18U.Relative therewith, at operating position 18D place, the 1st bottom, do not disposing plate with detecting sensor portion 14 cooresponding detected portion, but with detecting sensor 15～17 cooresponding detected portion action of configuration sheet (lower panel) 9a～9c respectively.
Fig. 3 is for showing the planar view of detecting sensor portion 14 structures.Fig. 4 is the instruction diagram of action of the detecting sensor portion 14 of displayed map 3.In the drawings, detecting sensor portion 14 is provided with the 1st sensor 22 and the 2nd sensor 23 that has or not action movie (plate) 5a～8a, the mutual unlike signal of output at same position.Here, slot part 14a is formed with magnetic field, and the 1st sensor 22 floats when inserting in slot part 14a at action movie (plate) 5a～8a, and output OFF signal floats when inserting in slot part 14a and carrying out magnetic screening output ON signal at action movie (plate) 5a～8a.On the contrary, the 2nd sensor 23 floats when inserting in slot part 14a at action movie (plate) 5a～8a, and output ON signal floats when inserting in slot part 14a and carrying out magnetic screening output OFF signal at action movie (plate) 5a～8a.That is, the 2nd sensor 23 is provided with the inversion device 24 that conversion shows attonity sheet (plate) 5a～8a signal.For the signal of the 1st sensor 22 outputs, have or not the signal (signal of anti-symbol) of action movie (plate) 5a～8a from the 23 output conversions of the 2nd sensor.
The structure of detecting sensor portion 15～17 is also identical with detecting sensor portion 14, that is, detecting sensor portion 15～17 is respectively equipped with the 1st sensor 22 and the 2nd sensor 23.
Detecting sensor portion 14～17 is electrically connected in the detection loop portion 25 that is equipped on elevator control device (not shown) respectively.Detect loop portion 25 according to each the 1st sensor 22 of detecting sensor portion 14～17 and the signal of each the 2nd sensor 23, the configuration structure of action movie (plate) 5～12 is encoded.Promptly, detect of the input of loop portion 25 with binary code " 1 " expression ON signal, input with binary code " 2 " expression OFF signal according to the signal from each detecting sensor 14～17, shows 8 binary codes of each operating position 18U～21U and 18D～21D.
Fig. 5 system is with the instruction diagram of the configuration structure numeralization demonstration of the plate of Fig. 1.Detect that loop portion 25 stores each operating position 18U～21U that 8 binary codes shown in Figure 5 show and in the data of the configuration structure of the action movie (plate) 5～12 of 18D～21D.Detect loop portion 25 with the data of the configuration structure of plate with compare according to 8 binary codes from the signal of detecting sensor portion 14～17, from try to achieve operating position according to the configuration data of the consistent plate of 8 binary codes of signal.
Below, action is described.
Detecting loop portion 25, is 8 binary codes from the signal encoding of detecting sensor portion 14～17, compares with the data of stored 8 binary codes.If coding conforms to, judge that detector 26 arrives the 1st top operating position 18U, can try to achieve the position of car 4.
If car 4 further rises, arrive the 2nd top operating position 19U, detecting sensor 14 and 17 is done magnetic screening by action movie (upper board) 6a and 6b respectively, and is same, detects detector 26 and whether arrives the 2nd top operating position 19U, tries to achieve the position of car 4.
Equally, if car 4 further rises, arrive the 3rd top operating position 20U, detecting sensor portion 14 and 16 does magnetic screening by action movie (upper board) 7a and 7b respectively.If car 4 arrives the 4th top operating position 21U, detecting sensor portion 14,16 and 17 does magnetic screening by action movie (upper board) 8a, 8b and 8c respectively.Thus, detect detector 26 respectively and whether arrive the 3rd top operating position 20U, the 4th top operating position 21U, try to achieve the position of car 4 respectively.
For example:, detect the OFF signal of loop portion 25 inputs from the 1st sensor 22 and the 2nd sensor 23 in the occasion that joint detection sensor 14 and the lead that detects loop portion 25 interrupt.That is, detecting 2 same signals importing in the loop portion 25 from detecting sensor portion 14.Detecting loop portion 25, be encoded simultaneously, comparing with the coding of the configuration structure of stored plate from the signal of detecting sensor 15～17 and 2 OFF signals from detecting sensor portion 14.Because from 2 same signals of the improper action of detecting sensor portion 14 input, so, inconsistent from the coding of the signal of detecting sensor portion 14～17 with the coding of plate configuration, can be judged as unusually.
As mentioned above, detecting sensor portion 14～17 is respectively equipped with at same position and has or not plate, export the 1st sensor 22 and the 2nd sensor 23 of mutual unlike signal, so, detecting loop portion 25 according to combination, can be respectively detecting with regard to the trouble free that has of detecting sensor portion 14～17 from the signal of the 1st sensor part 22 and the 2nd sensor 23.Thus, needn't be the position of detection car 4 as in the past, and need plate, can constitute more plate configuration structure by less number, dwindle the space that is provided with of detector 26, adapter plate 2a～2d and 3a～3d at each operating position configuration similar number.Therefore, can improve the degree of freedom etc. of the conceptual design of car 4 grades.
And, because the configuration of the plate of the 1st～the 4th top operating position 18U～21U is a complementary relationship with the pass of the plate configuration of the 1st～the 4th bottom operating position 18D～21D, so, when the position that car 4 is tried to achieve by detection loop portion 25 is the 1st top operating position 18U, whether the plate configuration of plate configuration and the 1st top operating position 18U that can detect the 1st bottom operating position 18D of corresponding the 1st top operating position 18U is complementary relationship, improves the reliability of car 4 position probing.
Again, near top layer flooring above the lifting hoistway 1 everything position 18U～21U disposes action movie (upper board) 5a, 6a, 7a and the 8a corresponding to detecting sensor portion 14, and below near the bottom flooring all operating position 18D～21D dispose action movie (lower panel) 9a, 10a, 11a, 12a corresponding to detecting sensor portion 15.Thus, combination can detect the position of car 4 by the detection that has or not plate that detecting sensor portion 14 and 15 carries out, and further improves the reliability of the position probing of car 4.
In the explanation of above-mentioned example, be to have utilized the situation of magnetic action to be illustrated, but described detecting sensor portion 14～17 also can be the detecting sensor portion that utilizes photoelectric action with regard to detecting sensor portion 14～17.
Shown in clear as described above, each detecting sensor portion in the device for detection of position of car body of elevator involved in the present invention is provided with at the 1st and the 2nd sensor that has or not same position action movie, the mutually different signal of output, detection loop portion passes through the combination from the signal of the 1st and the 2nd sensor, judge and have or not action movie, detect configuration structure, can the trouble free that have of detecting sensor portion be detected simultaneously, thus, can reduce detecting sensor portion number, reduce to be provided with the space.
