Abstract
The invention discloses an automatic detection and control method for braking force of an elevator, which belongs to the field of elevator control and brake technologies. The automatic detection and control method comprises the following steps of: successively detecting each group of brakes when the elevator is in the dormant state and reaches detection time; and when the detected brake is braked, determining that the group of brakes fails when a lift car displaces, then giving out a fault signal, and stopping using the elevator. The automatic detection and control method has the advantages that the braking force situation of the elevator is convenient to detect, faults can be removed in time, and the elevator is guaranteed to safely and reliably operate. Variation on a control system is small, and therefore the automatic detection and control method is easy to operate. The special parameter of the elevator does not need to be input, which is simple and effective, and the popularity of the control system is wider.
Description
Technical field
The invention belongs to elevator control and braking technology field, be specifically related to a kind of automatic detection control method of force for lift
Background technology
along with the city middle-high building increases, elevator is more and more come into people's life, becomes indispensable part in the urban life.But hear in recent years, the generation of elevator accident again and again.Have the expert that the accident of vertical lift is analyzed, wherein passenger's casualty accident 80% is owing to the extruding in car door district, shear and cause, the 15%th, because cause at the end of rushing to summit, squat of car, other is 5%.And the principal element at the end that causes pushing, shear, rush to summit, squat is electric-control system and braking failure.Braking force deficiency or brake troubles are the major causes that causes braking failure, are equally to cause one of improper mobile factor in car door district.So enough braking forces are the essential condition of guaranteeing the elevator safety reliability service.
are to the problems referred to above; Whether enough someone just found out a kind of force for lift method when testing the elevator dormant state; Be called " a kind of method that realizes brake sticking force detection of motor " like the disclosed name of Chinese invention patent Granted publication CN101269770B; Though this method can be guaranteed the safety of system's operation and hardware and in time detect the band-type brake fault that this method is bigger to the change of control system, needs the more special parameter of input; More complicated can't realize general.
For this reason, the applicant has carried out actively and the actv. trial, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is the automatic detection control method that a kind of force for lift will be provided; It can prevent the uncontrolled displacement that braking force deficiency or brake troubles cause; Then prevent the improper displacement of car, avoid accident to take place, guarantee the elevator safety reliability service.
Task of the present invention is accomplished like this, and a kind of automatic detection control method of force for lift may further comprise the steps:
(1) when elevator device is in dormant state, judge whether system arrives the band-type brake power sense cycle of setting, if, execution in step (2) then; If not, then finish this and detect operational process;
(2) system's control A group elevator brake band-type brake is opened separately, and keeps a period of time, judges whether lift car is subjected to displacement, if lift car is subjected to displacement, then system generates failure code, and Lift out of use; If lift car is not subjected to displacement, execution in step (3) then;
The control B of
(3) system group elevator brake band-type brake is opened separately, and keeps a period of time, judges whether lift car is subjected to displacement, if lift car is subjected to displacement, then system generates failure code, and Lift out of use; If lift car is not subjected to displacement, then finishes this and detect operational process.
in a concrete embodiment of the present invention, described A group elevator brake comprises one and above drg.
in another concrete embodiment of the present invention, described B group elevator brake comprises one and above drg.
the present invention is because after adopting said method, one of advantage that has: the convenient braking force situation that detects elevator, and timely trouble-shooting guarantees the safe and reliable operation of elevator; Advantage two, smaller to the change of control system, easy operating; Advantage three, need not import the peculiar parameter of elevator, effectively simple, the commonality of control system is wider.
Description of drawings
Fig. 1 is the flow chart of steps of the inventive method.
The specific embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the inspector that the makes Patent Office especially public; The applicant general combines accompanying drawing to elaborate with the mode of embodiment below; But the description to embodiment all is not the restriction to technical scheme of the present invention, anyly only is technical scheme category pro forma but not that substantial equivalent transformation all should be regarded as inventing according to what the present invention design had been done.
See also Fig. 1, the concrete implementation procedure of this technical scheme is:
(1) judges whether system arrives the band-type brake power sense cycle of setting (promptly automatically detecting the cycle of braking force) when elevator device is in dormant state, if, execution in step (2) then; If not, then finish this and detect operational process.
The control A of
(2) system group band-type brake is opened separately; Be to have only A group elevator brake to be in the band-type brake state in the system, and keep a period of time, judge whether lift car is subjected to displacement; If car is subjected to displacement; Confirm A group drg et out of order, then system generates failure code, and Lift out of use; If car is not subjected to displacement, execution in step (3) then.
The control B of
(3) system group band-type brake is opened separately; Be to have only B group elevator brake to be in the band-type brake state in the system, and keep a period of time, judge whether lift car is subjected to displacement; If car is subjected to displacement; Confirm B group drg et out of order, then system generates failure code, and Lift out of use; If car is not subjected to displacement, then finish this testing process.
principle of work: system is provided with the time period that elevator detects braking force automatically, when elevator is in dormant state and arrives detection time, detects successively and respectively organizes drg; When drg band-type brake to be detected, lift car confirms that then this group drg has fault if be subjected to displacement; Send breakdown signal, the withdraw from use elevator, this step is simple; Easy operating, commonality is wider.
In the present technique scheme; The group number of drg does not receive any restriction; Even two groups of above drgs are arranged, system can be provided with to detect successively and respectively organize drg until detecting that certain group drg has fault and withdraw from use elevator or detection of end operational process when respectively organizing drg and all being identified trouble free so
