At this moment, power supply unit 100 is just brought up to 15V to the 12V voltage level of battery and is offered rotary encoder 101, second pulse shaping unit 104, and standby counting machine 105.
Then, the process rotary encoder 101 and second pulse shaping unit 104 are to the impulse singla of standby counting machine 105 input 5V, and standby counting machine 105 also receives a voltage from power supply unit 100, to the 5V pulse count signal, and output counted data value.
After power up, if initialization do not finish, central process unit 106 just power supply just often (S6) read the data value C of standby counting machine 105 outputs, and whether canned data value B equates (S9) in judging the data value C that reads and going on foot S7.
According to the result who judges (S9), if data value B and C equate that central process unit 106 does not slide with regard to occurring in the decision-making system, and repeats step S3 to S9.
Simultaneously, according to the result of step S9, if data value B and C are unequal, central process unit 106 just detects the car position of corresponding data value C, and car position is corrected to the motion floor data, and judges whether to have taken place power fail (S5).
According to the result of step S5, when power supply just often, central process unit 106 is just normally operated car (S6) from the motion floor of proofreading and correct, storage data value B and C when power fail takes place, and repeat and go on foot S1 to S10.
At this moment, central process unit high level actuation signal PES who presets of 106 outputs and data value C, data value C is by data buffer 55 bufferings.
Then, on/following counting machine 35 writes from the data value of data buffer 55 outputs according to the preset enable signal PES by the high level of central process unit 106 output.
On/data value that following counting machine 35 writes by mouth Q0 to Q3 output according to the low level actuation signal PES that presets by central process unit 106 output.
Because offer central process unit 106 from the data value of last/following counting machine 35 outputs by latch 45 and data buffer 55, central process unit 106 can be controlled the normal running of car continuously.
Simultaneously, after system power supply is turn-offed, still force under the situation of car movement,, just omitted herein because the operation that the motion floor data is proofreaied and correct is identical with aforesaid situation.
As mentioned above, the motion floor data correction control apparatus of this elevator and the purpose of method thereof are more stably to operate elevator, its way is the storage data value relevant with car position when power fail takes place, the canned data value with power fail takes place before moment counting the enumeration data value compare, and according to the correction of comparative result controlled motion floor, thereby do not need because the mistake of motion floor data car movement to the bottom.That is to say that when power up, the position of the data of car after the correction of corresponding car begins to resume operation.
Although disclose most preferred embodiment of the present invention for explanation, those of skill in the art all can know, still can realize various modifications, supplementary sum replacement under the condition of scope that does not break away from claims of the present invention of the present invention and design.
