DETAILED DESCRIPTION

[0042] In order to deepen the understanding of the utility model, the utility model will be further described in detail in combination with the drawings and embodiments below, and the embodiments are only used to explain the utility model and do not constitute the limitation to the protection scope of the utility model.

[0043] Please refer to Figures 1 to 7 The utility model provides a locomotive signal integrated lamp box short circuit testing device, including first socket 11, multi-way relay control module 12, resistance meter 13, MCU controller 14, key input module 15;

[0044] The first socket 11 is provided with n wiring ends, and the i wiring end is electrically connected to the first test end of the resistance meter 13 through the switch normally open end of the i relay of the first relay unit in the multi-way relay control module 12 and is electrically connected to the second test end of the resistance meter 13 through the switch normally open end of the i relay of the second relay unit in the multi-way relay control module 12;

[0045] The control end of the i relay in the first relay unit is electrically connected to the i control end in the first group control end of the MCU controller 14;

[0046] The control end of the i relay in the second relay unit is electrically connected to the i control end in the second group control end of the MCU controller 14;

[0047] The control input end of the MCU controller 14 is electrically connected with the output end of the key input module 15.

[0048] Wherein, 1≤i≤n, n is an integer greater than 1, and i is an integer.

[0049] In this embodiment, the first socket 11 is used for connecting the integrated lamp box plug to be tested, and the specific model can be selected according to actual implementation needs. The specific operation circuit of the relay is as follows Figure 7 The control end of the relay is connected with the working voltage VCC on one side and connected with the control end of the MCU controller 14 through a triode on the other side. The operation process of the relay is as follows: when the control end of the MCU controller 14 outputs high level, the triode is turned on, and the normally open end of the relay switch is connected; when the control end of the MCU controller 14 outputs low level, the triode is turned off, and the normally open end of the relay switch is disconnected. It should be pointed out that each relay in the multi-channel relay control module 12 needs to correspond to the control end of the MCU controller 14, that is, the n relays of the first relay unit and the n relays of the second relay unit correspond to 2n control ends of the MCU controller 14. The normally open end of the i-th relay of the first relay unit is electrically connected to the first external node Z1 of the first test end of the resistance table 13, and the normally open end of the i-th relay of the second relay unit is electrically connected to the second external node Z2 of the second test end of the resistance table 13.

[0050] The locomotive signal integrated lamp box short circuit test device can realize automatic testing including one-key testing and item-by-item testing during specific testing. Assuming that n is 9, the first relay unit corresponds to A channel, and the relays of A channel are represented by A1-A9 respectively, the second relay unit corresponds to B channel, and the relays of B channel are represented by B1-B9 respectively. During specific testing, A1-A9 of A channel are controlled by the MCU controller 14 to output opening and closing instructions in turn, and B1-B9 of B channel output closing (corresponding to opening of A channel) and opening instructions (corresponding to closing of A channel). During one-key testing, for example, A1 of A channel is opened, and the remaining relays of A channel are closed, then B1 of B channel is closed, and the remaining relays of B channel are opened, which is equivalent to actively short-circuiting the remaining 8 channels of B channel except B1, so that whether there is a short circuit can be quickly judged. During item-by-item testing, for example, A1 of A channel is opened, and the remaining relays of A channel are closed, then B1 of B channel is closed, and B2-B9 of B channel are opened and closed in turn; A2 of A channel is opened, and the remaining relays of A channel are closed, then B2 of B channel is closed, and B1 and B3-B9 of B channel are opened and closed in turn, so that the short circuit between each cable can be tested item by item.

[0051] In a possible implementation, the first test interface 16 and the second test interface 17 are respectively electrically connected to the lines where the first test end and the second test end of the resistance table 13 are located.

[0052] In the embodiment, the first test interface 16 and the second test interface 17 can be understood as resistance test holes. By using conventional settings, the corresponding resistance values can be measured by the first test interface 16 and the second test interface 17 through an external multimeter, thereby improving the redundancy of the locomotive signal integrated lamp box short circuit test device.

[0053] In a possible implementation, as Figure 2 , the device housing 18 is further included.

[0054] The first socket 11, the display interface of the resistance meter 13, the key input module 15, the first test interface 16, and the second test interface 17 are arranged on the surface of the device housing 18.

[0055] The multi-channel relay control module 12, the MCU controller 14, and the remaining part of the resistance meter 13 are arranged inside the device housing 18.

[0056] In the embodiment, the device housing 18 can be made of conventional materials, and the specific shape and structure can be adjusted according to actual implementation needs.

[0057] In a possible implementation, the surface of the device housing 18 is further provided with a display screen 19.

[0058] The display screen 19 is electrically connected to the MCU controller 14.

[0059] The data output end of the resistance meter 13 is electrically connected to the data input end of the MCU controller 14.

[0060] In the embodiment, in addition to displaying the measured resistance value, the resistance meter 13 can also transmit the measured data to the MCU controller 14 for recording, and the MCU controller 14 controls the display screen 19 to display the corresponding measurement data.

[0061] In a possible implementation, as Figure 2 and Figure 3 , the surface of the device housing 18 is further provided with a first key switch group 20 and a mode switch 21.

[0062] The i th wiring end of the first socket 11 is further electrically connected to the first test end of the resistance meter 13 through the normally open end of the i th key switch in the first key switch group 20, and is electrically connected to the first end of the mode switch 21 through the normally closed end of the i th key switch in the first key switch group 20.

[0063] The second end of the mode switch 21 is electrically connected to the second test end of the resistance meter 13.

[0064] In the embodiment, the first key switch group 20 is composed of several conventional key switches. The normally open end of the i-th key switch in the first key switch group 20 is electrically connected to the first pair of external nodes Z1 of the first test end of the resistance meter 13. The second end of the mode switch 21 is connected to the second pair of external nodes Z2 of the second test end of the resistance meter 13.

[0065] The mode switch 21 is a conventional switch. The locomotive signal integrated lamp box short circuit testing device can also realize key mechanical testing during specific testing. Assuming that n is 9, when key mechanical testing needs to be realized, the mode switch 21 is pressed to be closed, and the first key switch group 20 can control the 9 connection terminals in the first socket 11 to be connected to the resistance meter 13, so as to display the corresponding test resistance value through the resistance meter 13. When automatic testing needs to be realized, the mode switch 21 is pressed to be opened, so as to prevent the first key switch group 20 from affecting the operation of the multi-channel relay control module 12.

[0066] In a possible implementation manner, as shown in Figure 2 、 Figure 4 、 Figure 5 The surface of the device housing 18 is also provided with a second socket 22, a second key switch group 23, and a switching switch 24.

[0067] The second socket 22 is provided with m connection terminals, the j-th connection terminal of which is electrically connected to the normally open end of the switching switch 24 through the normally open end of the j-th key switch in the second key switch group 23, and is electrically connected to the first end of the mode switch 21 through the normally closed end of the j-th key switch in the second key switch group 23.

[0068] The fixed end of the switching switch 24 is electrically connected to the first test end of the resistance meter 13.

[0069] The normally open end of the i-th key switch in the first key switch group 20 and the first test end of the resistance meter 13 are electrically connected through the normally closed end and the fixed end of the switching switch 24.

[0070] Wherein, 1≤j≤m, m is an integer greater than 1, and j is an integer.

[0071] In the embodiment, the second socket 22 is another socket type different from the first socket 11, and the specific model can be selected according to actual implementation needs. The second key switch group 23 is composed of several conventional key switches. The switching switch 24 can adopt a conventional rotary switch.

[0072] The locomotive signal integrated lamp box short circuit test device can also be switched in the key mechanical test mode during specific testing to test different plug types. Assuming that m is 6, when the key mechanical test is required, the mode switch 21 is pressed to make it closed, and at the same time, the switching switch 24 is adjusted to make the first test end of the resistance meter 13 communicate with the second key switch group 23 for testing the target connected to the second socket 22. The second key switch group 23 can control the 6 connection ends in the second socket 22 to communicate with the resistance meter 13, so as to display the corresponding test resistance value through the resistance meter 13. When the key mechanical test mode is required to test the target connected to the first socket 11, the switching switch 24 is adjusted to make the first test end of the resistance meter 13 communicate with the first key switch group 20. When the automatic test is required, the mode switch 21 is pressed to make it open, preventing the first key switch group 20 or the second key switch group 23 from affecting the operation of the multi-channel relay control module 12.

[0073] In a possible implementation, the first test end and the second test end of the resistance meter 13 are respectively electrically connected with a third test interface 25 and a fourth test interface 26.

[0074] In this embodiment, the third test interface 25 and the fourth test interface 26 can be understood as conventional resistance test holes, and the corresponding resistance values can be measured through the third test interface 25 and the fourth test interface 26 by an external multimeter, thereby improving the redundancy of the locomotive signal integrated lamp box short circuit test device.

[0075] In a possible implementation, as Figure 6 , a power module 27 is further included.

[0076] The power module 27 is electrically connected with the multi-channel relay control module 12, the resistance meter 13, and the MCU controller 14 respectively.

[0077] In this embodiment, the power module 27 is conventionally set to provide a stable working voltage for the locomotive signal integrated lamp box short circuit test device.

[0078] In a possible implementation, a power supply port 28 is arranged on the device housing 18.

[0079] The power supply port 28 is electrically connected with the power module 27.

[0080] In this embodiment, the power supply port 28 can provide an external power supply for the power module 27, and when a charging battery is included in the power module 27, the power module 27 can be charged through the power supply port 28.

[0081] In a possible implementation, the power supply port 28 is a Type-C interface.

[0082] In this embodiment, the power supply port 28 is a conventional Type-C interface, when the power supply module 27 is a conventional power supply circuit without a battery, a power bank or the like can be externally connected through the Type-C interface to provide a stable power supply for the locomotive signal integrated lamp box short circuit test device.

[0083] The above embodiments should not limit the utility model in any way, and any technical solution obtained by equivalent replacement or equivalent conversion falls within the protection scope of the utility model.
