Abstract
Non-universal equipment for elevator encryption relates to the field of elevator control and comprises a detector and a trigger, wherein the detector comprises a power source detector and a speed detector; the first output terminal of the power source detector is connected with the input terminal of the speed detector; the second output terminal of the power source detector is connected with the first input terminal of the trigger; and the output terminal of the speed detector is connected with the second input terminal of the trigger. The non-universal equipment, in which star connection control is separated from an elevator main board, can be mounted in an elevator of any type, so as to upgrade the elevator, endow the elevator with a star connection function and ensure the reliable action of star connection. Therefore, the non-universal equipment has higher performance-price ratio. Besides, the brake performance is directly proportional to the stalling of a permanent magnet motor of the elevator, so as to prevent harm to a human body caused by unexpected stop.
Description
Technical field
The utility model relates to a kind of elevator and encrypts non-common apparatus (including control program), belongs to the elevator control technology field.
Background technology
Since man of China Elevator Factory a large amount of employing permanent-magnet synchronous hoisting motor; Each brand elevator all is through the envelope star function of integrated control element and program controlled elevator in the elevator control main board; If therefore mainboard damages; Envelope star function just can't realize or misoperation, and because the producer that has does not seal the star function in early days, think that product up-gradation brought very big difficulty.
Summary of the invention
The utility model provides a kind of elevator to encrypt non-common apparatus (including control program); To solve in the prior art when mainboard damages; The envelope star function of elevator can't realize or misoperation; And for the elevator that does not seal the star function, be the problem of product up-gradation difficulty, the present invention adopts following technical scheme for this reason:
A kind of elevator is encrypted non-common apparatus; Comprise: detector and binary pair; Wherein detector comprises Power supply detector and speed detector; First mouth of Power supply detector and the input end of speed detector link to each other, and second mouth of Power supply detector links to each other with the first input end of binary pair, and the mouth of speed detector links to each other with second input end of binary pair.
The utility model makes the control of envelope star separate with elevator-mainboard, can be installed in the elevator of disposable type to make this elevator have envelope star function with this product of upgrading, and the reliable in action of control envelope star has high cost performance.Deceleration and stopping performance is directly proportional with the stall of elevator permanent magnet motor, prevents suddenly to stop the human injury.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation that the described elevator of the utility model is encrypted non-common apparatus.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of elevator that provides at the utility model embodiment is encrypted the technical scheme of non-common apparatus (including control program), and is as shown in Figure 1, comprising:
Further, when Power supply detector detected the power supply no-voltage, the notification triggers device triggered envelope star signal and interlocking signal, and envelope star signal makes the action of envelope star contactor, and interlocking signal makes the power contactor with elevator control cabinet carry out interlocking; When Power supply detector detects power supply voltage is arranged; And when speed detector detects elevator speed above command speed; The notification triggers device triggers envelope star signal and interlocking signal, and envelope star signal makes the action of envelope star contactor, and interlocking signal makes the power contactor with elevator control cabinet carry out interlocking.
Particularly, at first, whether Power supply detector detects power supply has voltage, if detecting power supply has voltage, then trigger envelope star signal and interlocking signal make the action of envelope star contactor, promptly the magneto-electric machine pig-tail wire is done short circuit and handles, to realize envelope star function; If detect the power supply no-voltage, then whether speed detector detects elevator speed above command speed, if surpass command speed; Then trigger is sealed star signal and interlocking signal; Make the action of envelope star contactor, promptly the magneto-electric machine pig-tail wire is done short circuit and handle, to realize envelope star function; Other situation except that said circumstances, the envelope star contactor all is failure to actuate.Wherein speed detector is that two-way speed to elevator detects simultaneously, when any direction speed surpasses command speed, all can make the action of envelope star contactor through trigger envelope star signal and interlocking signal, to realize envelope star function.
Particularly, the envelope star be meant permanent-magnet synchnorous gearless dragging machine with three phase winding pig-tail wires with lead or series resistance by star connection.Towing machine is as Thee-phase alternating current permanent-magnetic generator at this moment, and the unbalanced moment of elevator mechanical system drives the traction sheave running, and then electrical generator absorption mechanical energy is converted into electric energy, and the C/LOOP that forms through " envelope star " lead or resistance falls power consumption.When machine torque and motor electromagnetic torque balanced each other, towing machine promptly can travel at the uniform speed.Begin to use from gearless machine, " envelope star " is exactly to be used as safety protection function to use always, even has local certification body to require gearless elevator that envelope star controllable function must be arranged.
Detector in the utility model and binary pair all adopt existing integrated card or circuit to realize; Make the control of envelope star separate with elevator-mainboard; Can be installed in the elevator of disposable type makes this elevator have envelope star function with this product of upgrading; The reliable in action of control envelope star has high cost performance.Deceleration and stopping performance is directly proportional with the stall of elevator permanent magnet motor, and can make elevator be no more than command speed, prevents suddenly to stop the human injury.And the utility model cost is low, and is easy to use, compatible high, thereby is easy to promote.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model embodiment discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
