Operating box of lift car and control method thereof

Abstract

The invention relates to an operating box of a lift car and a control method thereof. The operating box comprises keys, an upper cover, a reply pad, a bottom box and an electronic function unit, wherein after the keys pass through the upper cover, the inner ends of the keys are opposite to the reply pad; the electronic function unit comprises a key lamp panel and a line control panel; the line control panel and the key lamp panel are connected and carry out signal transmission; the key lamp panel is separated from the inner ends of the keys by the reply pad and corresponds to the inner ends of the keys; the upper cover, the reply pad and the electronic function unit are fixedly connected and put into the bottom box; the line control panel is used for receiving the lift operating state information sent out by a lift control system and determining external information instructions; and the key lamp panel is used for completing line control of instant information of effective keys during operation of the lift. The operating box of the lift car of the invention has the advantages of simplifying the structure of a push-button device, solving the problem of chaos of multiple wires when the storey is high, saving the cost, being convenient to maintain and install, having strong disturbance resistance, high waterproof and dustproof grades and the like, and effectively improving the quality of the operating box of the lift.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an elevator car control box and a control method thereof. Background technique [0002] The elevator control box is an indispensable human-machine interface control device in the elevator car. The button device of the traditional elevator call box generally adopts an independent structure, see figure 1 , which includes a mechanical button 11', a button return member (such as a spring or a leaf spring) 12', a button housing 13', a circuit board 14', and a button fixing member 15'. Depend on figure 1 It can be seen that the existing independent button structure has many parts and complex structure, and each button must have corresponding multiple wires. At present, the floors are being built higher and higher, correspondingly, there are more and more buttons on the control box, and the corresponding number of wires is also doubled, which not only increases the cost, but also r...

Problems solved by technology

Depend on figure 2 It can be seen that there are first conductive film, insulating film, and second conductive film in the button mode of the elevator human-machine interface disclosed in the technical solution of the patent application, which increases the thickness of the entire control box, makes the control box bulky, and the cost is also high. It also increases the difficulty and cost of installation and maintenance
