[0002] In the modern industrial and information technology fields, key equipment infrastructures such as cabinet rooms, outdoor display screens and distribution boxes play a crucial role. These devices not only bear the heavy responsibilities of data transmission, storage and display, but also are the core guarantee to ensure the continuous and stable operation of production operations.

[0003] Facing the changeable natural environment, especially in bad weather conditions such as rain and fog, the humidity in the air increases, and even water droplets may directly drip. For devices such as precision electronic devices in cabinet rooms, display units of outdoor display screens and electrical components in distribution boxes, once water intrudes, it may not only cause device damage, but also trigger serious secondary disasters such as circuit short circuits and fires, having a huge impact on production operations.

[0004] In the prior art, key equipment infrastructures such as cabinet rooms, outdoor display screens and distribution boxes often lack timeliness and initiative in the face of water leakage situations. When water leakage occurs inside the device, it often needs to be detected by manual inspection or relying on other devices to determine whether water leakage occurs. This detection method will result in too long response time, and it is impossible to detect the water leakage situation inside the device in time, nor can corresponding measures be taken in time to cut off the power supply, thus increasing the risk of device damage and secondary disasters.

[0005] This is the deficiency of the prior art. Content of the Utility Model

[0014] Further, the system further includes a display terminal;

[0022] Further, the positioning water leakage induction rope is fixedly laid on the detected part inside the device to be detected through a card seat.

[0023] Further, the positioning water leakage induction rope adopts a four-core positioning water leakage induction rope.

[0024] Furthermore, the display terminal includes a mobile terminal and a PC terminal.

[0043] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the specific embodiments. Obviously, the following described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0044] Embodiment 1:

[0045] As shown Figure 1 in the figure, the utility model provides a water leakage induction power-off control system, which includes a positioning water leakage induction device, a PLC controller 3, and a power switch 4.

[0046] The positioning water leakage induction device includes a positioning water leakage induction rope 1 and a positioning water leakage controller 2. The positioning water leakage induction rope 1 is connected to the positioning water leakage controller 2 and is laid inside the device to be detected, for detecting whether there is water leakage inside the device to be detected, and generating a signal change when water leakage is detected. The positioning water leakage controller 2 is connected to the PLC controller 3, for generating a water leakage signal when detecting a signal change of the positioning water leakage induction rope 1 and sending the water leakage signal to the PLC controller 3.

[0047] The power switch 4 is arranged on the power circuit of the device to be detected. The power switch 4 is connected to the PLC controller 3, for controlling the on and off of the power circuit of the device to be detected.

[0048] The PLC controller 3 is used for controlling the power switch 4 to cut off the power circuit of the device to be detected when receiving the water leakage signal sent by the positioning water leakage controller 2.

[0049] It should be noted that the device to be detected includes but is not limited to key equipment infrastructures such as a cabinet room, an outdoor display screen, and a distribution box.

[0050] The positioning water leakage induction rope 1 usually consists of multiple (usually four) conductive lines. These lines are wrapped by insulating materials and tightly woven together. These lines are isolated from each other under normal circumstances, and the resistance value between them is very high, and current cannot flow through. When water leakage occurs in a certain area of the induction rope, the water will contact these conductive lines. Because water is a good conductor, it will form a conductive path between the originally isolated lines, resulting in a significant reduction in the resistance value. The sensor on the water leakage induction rope can detect this change in the resistance value and transmit it to the positioning water leakage controller 2.

[0051] Exemplarily, in this embodiment, the positioning water leakage induction rope 1 can be fixedly laid on the detected part inside the device to be detected. Those skilled in the art can use other devices to fixedly lay the positioning water leakage induction rope according to the actual situation.

[0052] Exemplarily, in this embodiment, the positioning water leakage induction rope 1 adopts a four-core positioning water leakage induction rope. Those skilled in the art can use other positioning water leakage induction ropes for detection according to the actual situation.

[0053] It should be noted that, in this embodiment, the power switch 4 can adopt a relay. Those skilled in the art can use other devices for setting according to the actual situation.

[0054] Specifically, the positioning leakage induction rope 1 is fixedly laid on the detected part inside the detected device through the card holder 8. When water drops fall on or contact the positioning leakage induction rope 1, the positioning leakage induction rope 1 will generate a signal change and send the generated signal change to the positioning leakage controller 2. When the positioning leakage controller 2 detects a signal change in the positioning leakage induction rope 1, it generates a leakage signal and sends the leakage signal to the PLC controller 3. When the PLC controller 3 receives the leakage signal sent by the positioning leakage controller 2, it controls the power switch 4 to disconnect the power circuit of the detected device to protect the detected device.

[0055] As an embodiment of the present invention, as Figure 2 shown, the system further includes a display terminal 5. The positioning leakage controller 2 is signal-connected to the display terminal 5 through a gateway 6 and is also used to calculate the leakage position information according to the signal change generated by the positioning leakage induction rope 1. The display terminal 5 is used to display the leakage position information.

[0056] Exemplarily, the display terminal 5 includes a mobile terminal and a PC terminal.

[0057] Exemplarily, the positioning leakage controller 2 is connected to the gateway 6 through an RS485 communication bus.

[0058] Since the length of each conductive line of the positioning leakage induction rope 1 is known and the distance between them is also fixed. When a leakage occurs, the positioning leakage controller 2 will measure the resistance change between each pair of adjacent lines in the positioning leakage induction rope 1 and calculate the distance that the water flow passes through. The positioning leakage controller 2 determines the leakage position information where the leakage occurs by comparing the resistance changes at different positions of each conductive line in the positioning leakage induction rope 1.

[0059] Specifically, the positioning leakage induction rope 1 is fixedly laid on the detected part inside the detected device through the card holder 8. When water drops fall on or contact the positioning leakage induction rope 1, the positioning leakage induction rope 1 will generate a signal change and send the generated signal change to the positioning leakage controller 2. When the positioning leakage controller 2 detects a signal change in the positioning leakage induction rope 1, it generates a leakage signal and sends the leakage signal to the PLC controller 3. At the same time, the positioning leakage controller 2 calculates the leakage position information according to the signal change generated by the positioning leakage induction rope 1 and sends the leakage position information to the display terminal 5 for display through the RS485 communication bus and the gateway 6. When the PLC controller 3 receives the leakage signal sent by the positioning leakage controller 2, it controls the power switch 4 to disconnect the power circuit of the detected device to protect the detected device.

[0060] It should be noted that in this embodiment, the positioning water leakage controller 2 can generate a water leakage prompt message when the positioning water leakage induction rope 1 generates a signal change, and send the water leakage prompt message and the water leakage position information to the display terminal 5 for display.

[0061] As an embodiment of the present utility model, as Figure 3 shown, the system further includes an audible and visual alarm 7, which is connected to the PLC controller 3 and is used for audible and visual alarm prompts. When the PLC controller 3 controls the power switch 4 to disconnect the power circuit of the device to be detected, it simultaneously controls the audible and visual alarm 7 to alarm.

[0062] The audible and visual alarm 7 is installed around the device to be detected, and is used to remind the staff that there is a water leakage problem with this device.

[0063] Specifically, the positioning water leakage induction rope 1 is fixedly laid on the detected part inside the device to be detected through the card seat 8. When water drops fall on the positioning water leakage induction rope 1 or come into contact with the positioning water leakage induction rope 1, the positioning water leakage induction rope 1 will generate a signal change, and send the generated signal change to the positioning water leakage controller 2. When the positioning water leakage controller 2 detects a signal change in the positioning water leakage induction rope 1, it generates a water leakage signal and sends the water leakage signal to the PLC controller 3. At the same time, the positioning water leakage controller 2 calculates the water leakage position information according to the signal change generated by the positioning water leakage induction rope 1, and sends the water leakage position information to the display terminal 5 for display through the RS485 communication bus and the gateway 6. When the PLC controller 3 receives the water leakage signal sent by the positioning water leakage controller 2, it controls the power switch 4 to disconnect the power circuit of the device to be detected to protect the device to be detected. At the same time, the PLC controller 3 controls the audible and visual alarm 7 to alarm, reminding the staff that there is a water leakage problem with this device.

[0065] The positioning water leakage induction rope 1 is laid inside the cabinet room 10.

[0066] It should be noted that the positioning water leakage induction rope 1 can be laid on the inner wall or the ground inside the cabinet room. In this embodiment, the positioning water leakage induction rope 1 can be laid on the ground inside the cabinet room.

[0067] Specifically, the positioning leak - sensing rope 1 is fixedly laid on the ground of the cabinet room 10 through the card holder 8, and is connected to the positioning leak - control controller 2 through the lead - out wire 9. When water drops fall on or come into contact with the positioning leak - sensing rope 1, the positioning leak - sensing rope 1 will generate a signal change and send the generated signal change to the positioning leak - control controller 2. When the positioning leak - control controller 2 detects a signal change in the positioning leak - sensing rope 1, it generates a leak signal and sends the leak signal to the PLC controller 3. At the same time, the positioning leak - control controller 2 calculates the leak position information based on the signal change generated by the positioning leak - sensing rope 1, and sends the leak position information to the display terminal 5 for display through the RS485 communication bus and the gateway 6. When the PLC controller 3 receives the leak signal sent by the positioning leak - control controller 2, it controls the power switch 4 to cut off the power circuit of the cabinet room to protect the safety of the electrical equipment in the cabinet room.

When water leakage is detected, the power supply is automatically cut off through the PLC controller and the power switch, and measures can be taken actively without external intervention, effectively reducing the risk of human error, avoiding further damage to the equipment by water, reducing the risk of equipment damage and secondary disasters, and greatly improving the processing efficiency of equipment water leakage.
