Abstract
The invention discloses a kind of lift fault signal pick-up method, it is with each level safety switch series connection of elevator, a termination pumping signal, and the other end is transported to signal processor; A resistance in parallel on every layer of safety switch, and its resistance is all inequality; According to after certain one deck elevator safety switch hinders open circuit for some reason, corresponding resistor incircuit and generation pressure drop are judged the elevator faults level by its output signal size.This method can accurately be judged the elevator faults level rapidly, and required device is simple, and expense is lower, uses easy to maintenance.
Description
The present invention is a kind of lift fault signal pick-up method.
Along with increasing of skyscraper, judge that rapidly and accurately elevator level safety switch fault has become the important topic that people pay close attention to.The elevator safety switch fault point detection device of Germany's production at present is to take to go between to microcomputer with every layer of safety switch, searches the method for breakdown switch level with microcomputer.Adopt this method, one 24 layers building need 24 * 2+1=49 root lead-in wire, and microcomputer need be provided with 49 signal entrance points.Cause the device complexity, cost strengthens, and the field activity amount is big.
The objective of the invention is to overcome the deficiency of prior art, provide a kind of required be provided with simple, lift fault signal pick-up method with low cost, easy to use.
Design plan of the present invention is: the termination excitation power supply after former each layer of elevator safety switch is connected in series, and the other end is transported to signal processor; A resistance in parallel on each layer safety switch, and its resistance is all inequality; According to after certain one deck safety switch hinders open circuit for some reason, its corresponding resistor incircuit, and produce pressure drop, judge elevator faults layer position from varying in size of output (picking up) signal.
Adopt this picking up signal method, can accurately judge elevator level fault rapidly, and be provided with simply, expense is lower, and installation and maintenance are convenient.
Description of drawings:
Accompanying drawing is for implementing the device scheme drawing of this method.
Among the figure: K(1), K(2), K(n) be elevator different levels safety switchs; R(1), R(n R(2)) be parallel resistor on the elevator different levels safety switch; R(L) be and this device bonded assembly signal processor input resistance.
Below in conjunction with accompanying drawing this method is implemented to do brief description.
Because safety switch one end and excitation power supply after the series connection are joined, and work as K(1) or K(2) or K(n) barrier disconnection for some reason, the resistance R that then is in parallel therewith (1) or R(2) or R(n) incircuit, and output signal to R(L through step-down).Because R(1), R(2), R(n) the resistance difference, then output signal varies in size, so according to the signal on the output signal (being R(L)) decidable elevator different faults level.
Claims (1)
1, a kind of lift fault signal pick-up method is characterized in that: the termination excitation power supply after former each layer of elevator safety switch is connected in series, and the other end is transported to signal processor; A resistance in parallel on each layer safety switch, and its resistance is all inequality; According to after certain one deck safety switch hinders open circuit for some reason, its corresponding resistor incircuit, and produce pressure drop, judge elevator faults layer position from varying in size of output (picking up) signal.
