[0031] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of the present invention. For those skilled in the art, the present invention can be applied to other similar scenarios based on these drawings without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0032] As indicated in this invention and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0033] While this invention makes various references to certain modules in systems according to embodiments of the invention, any number of different modules can be used and run on computing devices and / or processors. Modules are merely illustrative, and different aspects of the system and method may use different modules.

[0034] It should be understood that when a unit or module is described as "connected" or "coupled" to other units, modules, or blocks, it may refer to a direct connection or coupling, or communication with other units, modules, or blocks, or the presence of intermediate units, modules, or blocks, unless the context explicitly indicates otherwise. The term "and / or" as used herein may include any and all combinations of one or more of the related listed items.

[0035] Considering that in related technologies, each maintenance switch is connected to a separate test terminal, the wiring is complex, and each maintenance switch can only be tested individually in sequence.

[0036] In actual elevator operation, malfunctions may occur due to the simultaneous operation of multiple maintenance functions. Therefore, it is necessary to test multiple maintenance switches simultaneously.

[0037] To address the aforementioned technical problems, in one embodiment, as follows: Figure 1 As shown, an elevator control box maintenance device is provided, the device including: maintenance circuit board 10 and control circuit board 20 connected to the maintenance circuit board.

[0038] The maintenance circuit board 10 includes at least two maintenance switch circuit groups, at least two signal input terminals, and at least two signal output terminals. The signal input terminal of each maintenance switch circuit group is connected to a corresponding signal input terminal, and the signal output terminals of each maintenance switch circuit group are connected to each signal output terminal. Each maintenance switch circuit group includes at least two maintenance switch circuits, and the signal output terminals of each maintenance switch circuit in the same maintenance switch circuit group are connected to a corresponding signal output terminal. Each maintenance switch circuit includes a maintenance switch connected between the corresponding signal input terminal and the corresponding signal output terminal.

[0039] 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 sending a detection signal to one of the signal input terminals, scanning and detecting the feedback signals of each of the signal output terminals when the corresponding maintenance switches are closed, and detecting each maintenance switch based on the feedback signals.

[0040] Among them, maintenance switches include lighting switches, fan switches, driver switches, up switches, down switches, direct drive switches, independent switches, and firefighter switches, etc.

[0041] Based on actual testing needs, the maintenance switch circuit is divided into at least two maintenance switch circuit groups, and the maintenance switches in each maintenance switch circuit group can be tested simultaneously. For example, lighting switches, fan switches, up switches, and firefighter switches are divided into one group, and driver switches, down switches, direct drive switches, and independent switches are divided into another group.

[0042] After the maintenance switch circuit is divided, the maintenance switches are arranged in an array on the connection lines. For example, if there are 8 maintenance switches, they are arranged in a 4*2 array on the connection lines; if there are 9 maintenance switches, they are arranged in a 3*3 array on the connection lines.

[0043] In this embodiment, multiple maintenance switch circuits are divided into multiple maintenance switch circuit groups, with each group sharing a common signal output terminal, thus reducing wiring and the size of the maintenance circuit board. Simultaneously, multiple maintenance switches within each maintenance switch circuit group can be tested concurrently, meeting maintenance requirements.

[0044] During specific testing, the control unit outputs a high-level detection signal. For the maintenance switch circuit group to be tested, each maintenance switch in that circuit group is closed, and feedback signals from each signal output terminal are acquired through scanning detection. If the feedback signal is high-level, the maintenance switch outputting that feedback signal starts normally; if the feedback signal is low-level, the maintenance switch outputting that feedback signal does not start normally.

[0045] Considering the signal interference between the various maintenance switch circuits, in one embodiment, each maintenance switch circuit further includes an anti-interference component connected in series with each maintenance switch.

[0046] Specifically, the anti-interference component includes a diode, with the positive terminal of the diode connected to one end of the maintenance switch and the negative terminal connected to the corresponding signal output terminal, thereby achieving anti-interference using the diode.

[0047] It should also be noted that the electrical pins of the maintenance switches in this elevator control box maintenance device are connected to the maintenance circuit board by soldering. The connections between each maintenance switch and diode are directly made using the wires on the maintenance circuit board, reducing manual wiring and simplifying assembly.

[0048] Furthermore, in order to reduce the thickness of the elevator control box maintenance device, all components on the maintenance circuit board are electrically integrated, and the wiring on the back of the maintenance switch is removed.

[0049] The structural diagram of the circuit board is shown in the figure. Figure 2 As shown, the inspection circuit board 10 also includes mounting holes 101, which are directly fixed to the bottom plate of the control box by flange nuts, facilitating installation and disassembly.

[0050] In one example embodiment, the circuit diagram for troubleshooting the switch circuit is as follows: Figure 3 As shown, the first, second, third, and fourth maintenance switch circuits form one maintenance switch circuit group; the fifth, sixth, seventh, and eighth maintenance switch circuits form another maintenance switch circuit group. The first maintenance switch circuit is connected between input terminal H2 and output terminal L1, and includes a first maintenance switch K1 and a first diode D1; the second maintenance switch circuit is connected between input terminal H2 and output terminal L2, and includes a second maintenance switch K2 and a second diode D2; the third maintenance switch circuit is connected between input terminal H2 and output terminal L3, and includes a third maintenance switch K3 and a third diode D3; the fourth maintenance switch circuit is connected between input terminal H2 and output terminal L4, and includes a fourth maintenance switch K4 and a fourth diode D4. The fifth maintenance switch circuit is connected between input terminal H1 and output terminal L1, and includes the fifth maintenance switch K5 and the fifth diode D5; the sixth maintenance switch circuit is connected between input terminal H1 and output terminal L2, and includes the sixth maintenance switch K6 and the sixth diode D6; the seventh maintenance switch circuit is connected between input terminal H1 and output terminal L3, and includes the seventh maintenance switch K7 and the seventh diode D7; the eighth maintenance switch circuit is connected between input terminal H1 and output terminal L4, and includes the eighth maintenance switch K8 and the eighth diode D8.

[0051] The specific testing process is as follows:

[0052] Step 1: The control unit outputs a high level to input terminal H1 and a low level to input terminal H2. Close the first maintenance switch K1, the second maintenance switch K2, the third maintenance switch K3, and the fourth maintenance switch K4. The control unit detects the feedback signal of each switch detection circuit through output terminals L1, L2, L3, and L4 respectively. If the feedback signal is high, the corresponding maintenance switch in the switch detection circuit starts normally; otherwise, it does not start normally.

[0053] Step 2: The control unit outputs a high level to input terminal H2 and a low level to input terminal H1. Close the fifth maintenance switch K5, the sixth maintenance switch K6, the seventh maintenance switch K7, and the eighth maintenance switch K8. The control unit detects the feedback signal of each switch detection circuit through output terminals L1, L2, L3, and L4 respectively. If the feedback signal is high, the corresponding maintenance switch in the switch detection circuit starts normally; otherwise, it does not start normally.

[0054] In another example embodiment, the circuit diagram for the troubleshooting switch circuit is as follows: Figure 3 As shown in the figure, there are 9 maintenance switches arranged in a 3x3 array on the line. The specific testing process is the same as in the example embodiment above, so it will not be described again.
