Embodiment Construction

[0014] In order to enable the examiners of the patent office, especially the public, to understand the technical essence and beneficial effects of the present invention more clearly, the applicant will describe in detail below in conjunction with the accompanying drawings in the form of embodiments, but none of the descriptions of the embodiments is a description of the present invention. Restriction of the technical solution of the invention, any equivalent transformation made according to the concept of the present invention which is only formal but not substantive shall be regarded as the scope of the technical solution of the invention.

[0015] see figure 1 , the specific implementation process of the technical solution is:

[0016] (1) When the elevator system is in a dormant state, judge whether the system has reached the set brake force detection cycle (that is, the cycle of automatic detection of the braking force), if yes, perform step (2); if not, end this ti...

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 [0001] The invention belongs to the technical field of elevator control and braking, and in particular relates to an automatic detection and control method of elevator braking force . Background technique [0002] With the increase of high-rise buildings in cities, elevators are increasingly entering people's lives and becoming an indispensable part of urban life. But in recent years, frequently hear the occurrence of elevator accidents. Some experts have analyzed the accidents of vertical elevators. Among them, 80% of the passenger casualties are caused by the extrusion and shearing of the car door area, 15% are caused by the car's rushing to the top and squatting at the bottom, and the others are 5%. The main factors that lead to extrusion, shearing, top rushing, and squatting are the failure of the electronic control system and brakes. Insufficient braking force or brake failure is the main cause of brake failure, and it is also one of the factors cau...
