In practice, also can add following function to this Aulomatizeted Detect cabinet:
Whether for sedan-chair top bus box for rear opening elevator, whether be equipped with rear light curtain control module (Fig. 3 sequence number 5) and back door machine control module (Fig. 3 sequence number 8), this detecting box provides two kinds of different detection schemes.Before starting to detect, whether staff can possess rear opening controlling functions according to by inspection bus box, is undertaken selecting (Fig. 4) by the rotary switch SK3 transferring switch module 104.When main trace routine starts, the program in PLC control module 106 can judge according to the selection result of rotary switch SK3, thus enters different trace routines.Likely there is the problem (namely selector switch SK3 dials the wrong number) selecting mistake for staff, in PLC control module 106, possessed corresponding defence program.Once find that the bus box detected is not inconsistent with selecting signal, device is by main for stopping trace routine, and driving display module to show corresponding failure code, prompting staff carries out selection adjustment, can avoid due to the mistake on operated by personnel and affect last testing result.
As shown in Figure 5, Figure 7, due to signal common point, electrical voltage point, earth point in the bus box of sedan-chair top, often, this detecting box increases K1 ~ k7 seven auxiliary reclays, carries out interblock interference respectively to signal 601,602 and earth point PE.PLC internal processes first exports high level from Y50 point, drive relay K 1 action, three pairs of normally opened contacts 5 and 9 of K1 in Fig. 5, 6 and 10, 7 and 11, normally opened contact 8 and 12 adhesive of K1 in Fig. 7, No. 2 hole output low levels immediately of No. 50 plug-in units in pick-up unit, if the respective lines non-fault in the bus box of sedan-chair top, then now PLC input point X65 in Fig. 5, X66, X67 should pass through No. 33 plug-in units No. 1 hole, No. 37 plug-in units No. 1 hole, No. 35 plug-in units No. 4 holes receive low level, this step completes, trace routine redirect enters next step, Y51 point is driven to export, so carry out successively.In testing process, if find there is fault in the circuit in bus box, namely the output of Y50 ~ Y56 is abnormal with the input logic relation of X65 ~ X75, the program preset in the middle of PLC control module 106 will be diagnosed voluntarily according to the output input relation of Y50 ~ Y56 and X65 ~ X75, stop follow-up detecting step, accurately find faulty line, drive display module to show corresponding failure code, guiding work personnel carry out fault handling.
As Fig. 9, cage top overhauling is set in the bus box of sedan-chair top and runs module, comprise SDT(sedan-chair top emergency stop switch), DJ(cage top overhauling run switch), DKZ(runs and confirms switch), DMS(sedan-chair top goes up run switch slowly), DMX(sedan-chair top descends run switch slowly).This detecting box has an independently detecting pattern for this modular design, and whether correct for the connection detecting circuit in the middle of this module, whether button operates normally.After device for opening power switch, system just enters this detecting pattern automatically, and system drive Y72 exports high level to No. 46 plug-in units No. 2 holes, and now the DJ switch on bus box is allocated to inspecting state, pilot lamp 1 is lighted immediately; After pilot lamp 1 is lighted, system drive Y73 exports high level to No. 32 plug-in units No. 1 hole, and now pilot lamp 3 is lighted, then presses the SDT switch on bus box, and pilot lamp 2 is lighted; After pilot lamp 2 is lighted, system drive Y74 exports high level to No. 46 plug-in units No. 1 hole, and press DKZ and DMS button, pilot lamp 5 lights immediately simultaneously, presses DKZ and DMX button simultaneously, and pilot lamp 6 is lighted; Now again DJ switch is allocated to normal condition, pilot lamp 4 is lighted.This pattern coordinates the pushbutton switch that bus box is equipped with to carry out detection operation, and carry out breakdown judge by the situation of lighting of pilot lamp on pick-up unit 1 ~ 6, simple to operate, failure message is directly perceived.The present invention also designs X75 and X76 two circuit low level check points, avoids the wiring error of 12-01,26-01,26-02 insert hole in inspection travel module, guarantees the accurate of testing result.
Because some apparatus for controlling elevator is equipped with cage illumination fan intelligent control module voluntarily, just without the need to increasing this module again in the sedan-chair top bus box used.For this reason, this detecting box devises the selection detecting pattern (as shown in Figure 10) of a set of bus box cage illumination fan intelligent control module.Staff can, after open detection cabinet master switch, according to the concrete model of bus box to be checked, select bus box to be checked whether to be equipped with cage illumination fan intelligent control module by the K4 selector switch of selector switch module.Pen-down detection button after waiting to select, in PLC control module 106, according to selection result, pre-set programs will determine whether redirect enters this detecting pattern.
As shown in Fig. 3, Fig. 7, when bus box is not equipped with cage illumination fan intelligent control module, what connect in 47-01 and 49-01 insert hole is the low-voltage of DC24V, and when bus box is equipped with cage illumination fan intelligent control module, this module is built-in with KZM relay (coil voltage is AC220V), what connect in 47-01 and 49-01 insert hole is the high voltage of AC220V, and requires that insert hole 27-01,27-04 in the bus box corresponding to 47-01,47-04 are controlled by the normally closed contact of KZM relay.For this problem, this detecting box adds the auxiliary control of K8, K9, K10 tri-relays.After Pen-down detection button, pre-set programs in PLC control module judges according to the selection result of SK4 switch, if examine bus box and be not equipped with cage illumination fan intelligent control module, the Y0 output low level in Fig. 6, the X10 in Fig. 4 receives low level signal, this loop is normal, if X10 does not receive low level signal, then there is fault in this loop, and PLC will stop follow-up detecting step, driving malfunction display board shows corresponding failure code, and guiding work personnel carry out fault handling; If examine bus box and be equipped with cage illumination fan intelligent control module, then PLC drives Y57 to export high level, relay K 8 action, K8 normally closed contact in Fig. 5 and Fig. 6 disconnects, and be provided with inductance L 1, L2, effectively can intercept the input of high voltage alternating current, avoid X10, Y0 point of the high voltage of 47-01,49-01 to PLC to damage to some extent.In Figure 10, the normally opened contact of K8 closes simultaneously, now relay K 10 action, X64 no signal inputs, if X64 still has signal to input, represent that the loop in bus box between 27-01 and 27-04 exists fault, PLC control module 106 will stop follow-up detecting step, drives display module to show corresponding failure code; If X64 no signal inputs, continuation drives Y70 to export by PLC control module 106, relay K 9 action, the KZM actuating of relay in bus box, normally closed contact disconnects, K10 relay coil dead electricity, normally closed contact closes, and X64 input point has low level voltage to input, and result is normal.If now X64 inputs without low level, then represent that the loop in bus box before 27-01 and 29-01 exists fault, PLC control module 106 will stop follow-up detecting step, and drive display module 103 to show corresponding failure code, guiding work personnel carry out fault handling.
Likely there is the problem (namely selector switch SK4 dials the wrong number) selecting mistake for staff, in PLC control module 106, possessed corresponding defence program simultaneously.Once find that the bus box detected is not inconsistent with selecting signal, by this module trace routine of stopping, and drive display module 103 to show corresponding failure code, prompting staff carries out selection adjustment, avoids manual operation mistake and affects last testing result.
