The term "and/or" as used herein may include any and all combinations of one or more of the associated listed items.
In the related art, each maintenance switch is correspondingly connected with one detection terminal respectively, wiring is complex, and each maintenance switch can only be detected independently in sequence.
In the actual working process of the elevator, faults can be generated due to simultaneous operation of a plurality of maintenance functions. Based on this, it is necessary to detect a plurality of inspection switches at the same time.
In view of the foregoing technical problem, in one embodiment, as shown in fig. 1, there is provided an elevator control box maintenance apparatus, the apparatus comprising: an inspection circuit board 10 and a control circuit board 20 connected to the inspection circuit board.
The overhaul circuit board 10 comprises at least two overhaul switch circuit groups, at least two signal input terminals and at least two signal output terminals, the signal input ends of the overhaul switch circuit groups are respectively connected with a corresponding signal input terminal, the signal output ends of the overhaul switch circuit groups are commonly connected with the signal output terminals, the overhaul switch circuit groups comprise at least two overhaul switch circuits, the signal output ends of the overhaul switch circuits in the same overhaul switch circuit group are respectively connected with a corresponding signal output terminal, and the overhaul switch circuits comprise overhaul switches connected between the corresponding signal input ends and the corresponding signal output ends.
The control circuit board 20 is connected to each of the signal input terminals and each of the signal output terminals, and includes a control unit for sequentially transmitting a detection signal to one of the signal input terminals, scanning and detecting a feedback signal of each of the signal output terminals in response to each of the inspection switches being closed, and detecting each of the inspection switches based on each of the feedback signals.
Wherein the service switch is, for example, a lighting switch, a fan switch, a driver switch, an up switch, a down switch, a straight running switch, an independent switch, a firefighter switch, etc.
According to the actual detection requirement, the overhaul switch circuit is divided into at least two overhaul switch circuit groups, and the corresponding functions of the overhaul switches in each overhaul switch circuit group can be detected simultaneously. For example, the lighting switch, fan switch, up switch, firefighter switch are grouped together, and the driver switch, down switch, straight switch, and independent switch are grouped together.
After the overhaul switch circuit group is divided, the overhaul switches are arranged in an array on the connecting circuit. For example, in the case where there are 8 service switches, the service switches are arranged in an array of 4*2 on the connection line; in the case of 9 service switches, the service switches are arranged in an array of 3*3 on the connection line.
In the present embodiment, the plurality of service switching circuits are divided into a plurality of service switching circuit groups, each group multiplexing a common signal output terminal, and thus the wiring and the volume of the service circuit board are reduced. Meanwhile, a plurality of maintenance switches in each maintenance switch circuit group can be detected simultaneously, so that the detection requirement of maintenance functions is met.
When the detection is carried out, the detection signal output by the control unit is a high-level signal, each maintenance switch in the maintenance switch circuit group is closed aiming at the maintenance switch circuit group to be detected, and the feedback signal of each signal output terminal is obtained in a scanning detection mode. If the feedback signal is a high-level signal, the maintenance switch outputting the feedback signal is normally started, and if the feedback signal is a low-level signal, the maintenance switch outputting the feedback signal is not normally started.

Specifically, the anti-interference component comprises a diode, the anode of the diode is connected with one end of the maintenance switch, the cathode of the diode is connected with the corresponding signal output end, and the anti-interference is realized by the diode.
It is still to be noted that, the electrical pin of the maintenance switch in this elevator control box maintenance device passes through welded connection with the maintenance circuit board, connects between each maintenance switch, the diode and directly adopts the wire connection on the maintenance circuit board, reduces artifical wiring, makes the assembly simple.
Furthermore, in order to reduce the thickness of the overhaul device of the elevator control box, all elements on the overhaul circuit board are electrically integrated, and the wiring on the back of the overhaul switch is removed.

The specific detection process is as follows:
the first step: the control unit outputs a high level to the input terminal H1 and a low level to the input terminal H2. The first overhauling switch K1, the second overhauling switch K2, the third overhauling switch K3 and the fourth overhauling switch K4 are closed. The control unit detects feedback signals of the switch detection circuits through the output terminals L1, L2, L3 and L4, respectively. If the feedback signal is high, the maintenance switch in the corresponding switch detection circuit is normally started, otherwise, the maintenance switch is not normally started;
and a second step of: the control unit outputs a high level to the input terminal H2 and a low level to the input terminal H1. The fifth overhaul switch K5, the sixth overhaul switch K6, the seventh overhaul switch K7 and the eighth overhaul switch K8 are closed. The control unit detects feedback signals of the switch detection circuits through the output terminals L1, L2, L3 and L4, respectively. If the feedback signal is high, the maintenance switch in the corresponding switch detection circuit is started normally, otherwise, the maintenance switch is not started normally.
