The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Please consult Fig. 1 and Fig. 2 in the lump; Its building operation that provides for the utility model preferred embodiments is formed scheme drawing with the module of the intelligent control system 100 of elevator, intelligent control system 100 comprise two motors 10, processing unit 20, tachogenerator 30, LOAD CELLS 40, alarm unit 50, display unit 60 and be electrically connected at LOAD CELLS 40 and this processing unit 20 between signal transmitting device 70.Processing unit 20 all electrically connects with two motors 10, tachogenerator 30, LOAD CELLS 40, alarm unit 50 and display unit 60.In this embodiment, display unit 60 is a text display, is appreciated that in other embodiments, and display unit 60 can also be display devices such as touch-control read-out, LCD display, charactron.

Processing unit 20 is used to control the operation of intelligent control system 100; Motor 10 is used to drive the up-down of building operation with elevator 200; Tachogenerator 30 is used under the control of processing unit 20, measuring the moving velocity of building operation with elevator 200, and LOAD CELLS 40 is used under the control of processing unit 20, measuring the real-time weight of building operation with elevator 200.Alarm unit 50 is used for when building operation surpasses a predetermined speed range with the moving velocity of elevator 200 prompting reports to the police, and is used for prompting warning when building operation surpasses a preset weight value with the real-time weight of elevator 200.Display unit 60 is used to show rising or falling speed, load carrying ability and the prompt messages of building operation with elevator 200.Alarm unit 50 also is used for the various faulty conditions of each travel switch of operational process are reported to the police, and does corresponding demonstration by display unit 60.

Building operation comprises the cage 11 with gear, the guide rail bracket 12 with tooth bar, head sheave 13, steel rope 14, counterweight body 15, tumbler 16 and bearing 17 with elevator 200.

Please combine Fig. 3, guide rail bracket 12 sets up on the ground, and its top is fixed with head sheave 13.The top of bearing 17 fixed cap cages 11, tumbler 16 is articulated in bearing 17, the tooth bar engagement of the gear of cage 11 and guide rail bracket 12, thus cage 11 can move along the tooth bar of guide rail bracket 12, and motor 10 is arranged on cage 11 tops and moves with cage 11.Tumbler 16 comprises rope roll assembling 161.Steel rope 14 is hung on the head sheave 13; And an end of steel rope 14 is fixed in the rope roll assembling 161; Thereby can twine and be contained in the rope roll assembling 161; The other end of steel rope 14 is fixed on the counterweight body 15, thus counterweight body 15 do and the rightabout perpendicular movement of cage 11 operation along the counterweight slideway of guide rail bracket 12, thereby reduced the propulsive effort of motor 10.

Tachogenerator 30 is installed on the guide rail bracket 12, is used to calculate guide rail bracket 12 gears ingear number of teeth on the tooth bar of guide rail bracket 12 in a period of time, and sends this number of teeth to processing unit 20.Processing unit 20 is according to the moving velocity of the Tooth Number Calculation cage 11 in this known time section, that is, this number of teeth is the moving velocity of cage 11 divided by this known time.Alarm unit 50 judges whether this moving velocity exceeds this predetermined speed range, if then send prompt messages and shown by display unit 60.Therefore; Velocity anomaly appears in cage 11 when in a single day moving; Intelligent control system 100 will be before other fender guard (like anti-falling safety device) move; Force to break off motor and band-type brake power supply in advance, play the effect that prevents trouble before it happens, and have sound and light alarm and character image on display unit 60, to show the fault prompting.

LOAD CELLS 40 is installed in drive of motor plate 21 and is connected bearing pin 23 inside on the otic placode 22 with cage, is used for the stress of this bearing pin of sensing and produces the correspondent voltage value, and send this magnitude of voltage to signal transmitting device 70, carries out signal by signal transmitting device 70 and amplifies.This magnitude of voltage has characterized the real-time weight of cage 11, and the real-time weight of cage 11 comprises the weight and the load carrying ability of cage 11 itself.Therefore, these different magnitudes of voltage are represented the real-time weight of different cage 11, can be pre-formed a voltage weight contrast table through experiment thus.This voltage weight contrast table is stored in the processing unit 20 in advance, and therefore, processing unit 20 is tabled look-up in this voltage weight contrast table according to this magnitude of voltage can learn the real-time weight of cage 11.Alarm unit 50 judges that the real-time weight of cage 11 does not exceed this preset weight value, if then send prompt messages and shown by display unit 60.

Processing unit 20 is used to also to judge that the real-time weight of cage 11 belongs to preset underloading scope and still is in preset heavily loaded scope; When the real-time weight of judging cage 11 belongs to this preset underloading scope; 10 operations of motor of processing unit 20 controls; When the real-time weight of judging cage 11 belongs to this preset heavily loaded scope, 10 operations of two motors of processing unit 20 controls.The load of the electrode 10 in this embodiment is that the weight of cage 11 adds load carrying ability, deducts the weight of counterweight body 15 again.In other embodiments, can also do further division, be divided into zero load, underloading, heavy duty the real-time weight of cage 11; Correspondingly the quantity of motor 10 is not limited to two of this embodiment, can also be more, and Ru Santai; When being judged as zero load, move a motor 10; When being judged as underloading, move two motors 10; When being judged as heavy duty, move three motors 10.

Therefore, utilization intelligent control system 100 can reduce electric energy loss effectively.If by work every day 8 hours (according to observation, building operation uses the mode of operation of elevator 20040% to be underloading), 40% single machine operation, 0.8 yuan/degree of commercial power calculates, and can practice thrift 50 yuan of left and right sides electricity charge in theory.

In sum, the intelligent control system 100 that the utility model provides is through the setting of LOAD CELLS 40; Energy savings reduces the electric energy loss of equipment, and the text display through faulty condition has shortened the time of searching fault greatly simultaneously; Improve the efficient of maintenance and repair work, promoted the craftmanship of complete machine, and passed through the setting of tachogenerator 30; Velocity anomaly appears when in a single day cage 11 is moved; This control system will be forced to break off motor and band-type brake power supply before other fender guard (like anti-falling safety device) does not move in advance, played the effect that prevents trouble before it happens.So intelligent control system 100 can energy-conserving and environment-protective and can be made building operation have the preferable life-span with elevator 200.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
