DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1-9 The present embodiment provides a cabinet PDU intelligent monitoring system, including a control terminal, an intelligent monitoring module, a wire harness module and a stress monitoring module. The intelligent monitoring module, the wire harness module and the stress monitoring module are all connected to the control terminal in communication. The wire harness module is used to bundle the wires. The control terminal is preset with an image drawn according to stress and tightening force. The image drawn according to stress and tightening force can determine the stress and tightening force of the wires after the wires are bundled under normal circumstances. When the stress changes, the tightening force at this time must also change. However, after the wires are bundled, the changes in stress and tightening force are inversely proportional. That is, if the stress increases, the corresponding tightening force must be reduced, so that the stress can be reduced again. The stress monitoring module is used to monitor the stress of the wires at the wire bundling location and upload the monitored data to the control terminal. The control terminal compares the data from the stress monitoring module with the image drawn based on the stress and tightening force preset in the control terminal. The control terminal controls the wire bundling module to adjust the tightening force of the wires to reduce the mechanical stress at the wire bundling location. The wire bundling module here includes a wire tie 607 and a wire tie buckle. The wire tie 607 is communicatively connected to the control terminal. The wire tie 607 drives the wire tie buckle to tighten the wires. The stress monitoring module is arranged on the wire tie buckle.

[0032] At present, when the cabinet PDU intelligent monitoring system is monitoring, many sensors are usually set in the cabinet to make the monitoring function of the monitoring system more comprehensive. However, this design will also increase the number of wires in the cabinet, resulting in the wires in the cabinet being messy. In this regard, most staff members use cable ties to bundle the wires to avoid the mess of the wires. However, in actual use, the inventor found that there are still some problems in the current cabinet PDU intelligent monitoring system: because the cabinet PDU intelligent monitoring system will generate heat during use, and the intelligent monitoring system needs to continue monitoring. When encountering hot weather, the heating of the wire is more obvious, and the wire may expand when heated, and the expansion length of the wire will increase. The position where the cable tie is used to bundle and fix the wire limits the change in the length of the wire. At this time, the position where the cable tie is used to bundle and fix the wire will generate mechanical stress. In the long run, this mechanical stress may cause the wire to break or the connection to loosen, affecting the stability and safety of the circuit, and ultimately affecting the use of the PDU intelligent monitoring system.

[0033] In order to solve the above problems, in this embodiment, a stress monitoring module is provided on the cable tie, and an image drawn according to stress and tightening force is preset in the control terminal. When the stress changes, the tightening force at this time also changes accordingly. However, after the wires are bundled, the stress and the tightening force change inversely, that is, if the stress increases, the corresponding tightening force must be reduced, so that the stress can be reduced again. The stress monitoring module is used to monitor the stress of the wires at the cable tie location and upload the monitored data to the control terminal. The control terminal compares the data of the stress monitoring module with the image drawn according to stress and tightening force preset in the control terminal. The control terminal controls the cable tie module to adjust the tightening force of the wires to reduce the mechanical stress at the wire tie location, thereby solving the problem that when encountering hot weather, the heating of the wires is more obvious, the wires expand due to heat, and the position where the cable tie is used to bundle and fix the wires limits the length change of the wires. At this time, mechanical stress will be generated at the position where the cable tie is used to bundle and fix the wires. In the long run, this mechanical stress may cause the wires to break or the connection to loosen, affecting the stability and safety of the circuit, and ultimately affecting the use of the PDU intelligent monitoring system.

[0034] Because it is hot weather, and the stress monitoring module is set on the cable buckle, but the different locations where the stress monitoring module is set will have different effects on stress monitoring. If the stress monitoring module cannot monitor the stress change in the first time, then as time goes by, the change is monitored only after the wire is heated and expanded, which may easily cause the wire to be squeezed and deformed. In order to solve this problem, in one embodiment, the stress monitoring module includes a stress sheet and a plurality of stress sensors for detecting the strain of the wire. The stress sensor is used to monitor the change of the tension borne by the wire. The stress sheet and the plurality of stress sensors are both communicatively connected to the control terminal. The plurality of stress sensors are respectively arranged in the middle and both ends of the wire in the cable buckle. The plurality of stress sensors are respectively arranged in the middle and both ends of the wire in the cable buckle. Because the middle and both ends of the wire are special positions, they are selected as the key parts of the wire. It is better to install stress sensors at this position. These sensors can monitor the change of the tension borne by the wire in real time. The stress sheet is arranged on the inner wall of the cable buckle, and the strain sheet is used to measure the strain of the wire, so as to calculate its stress change, so that in hot weather, the stress monitoring module can monitor the stress change in the first time.

[0035] In addition, in order to make the cabinet PDU intelligent monitoring system monitor more comprehensive information and ensure better effect when the cabinet PDU intelligent monitoring system is used, in one embodiment, the intelligent monitoring module includes a shell 1, a fixing seat 2 is fixedly installed on the top of the shell 1, mounting seats 3 are fixedly installed on both sides of the shell 1, a connecting seat 4 is fixedly installed on the bottom of the shell 1, a fixing frame 5 is fixedly installed between the two sides inside the shell 1, a slide groove 505 is fixedly provided on the top of the fixing frame 5, a digital current sensor 507 is movably installed on the top of the slide groove 505, a temperature and humidity detector 508 is movably installed on one side of the digital current sensor 507, an infrared monitor 509 is movably installed on one side of the temperature and humidity detector 508, and the infrared monitor 509 A four-way server 510 is movably installed on one side, a thermal airflow detector 511 is movably installed on one side of the four-way server 510, a mounting frame 6 is fixedly installed on the bottom of the fixing frame 5, and a storage bottle 7 is equidistantly installed at the bottom end of the inner shell 1. The digital current sensor 507 here is used to monitor the current consumption of the server and equipment to prevent overload. The temperature and humidity detector 508 is used to ensure the stability of the environment in the server room to prevent equipment damage caused by overheating or excessive humidity. The infrared monitor 509 here is used to monitor the opening and closing of the cabinet to ensure data security. The four-way server 510 is used to centrally manage multiple monitoring points to achieve real-time monitoring and alarm. The thermal airflow detector 511 can help optimize the cooling system to ensure the normal operation of the server, such as Figure 3As shown, through the mutual cooperation among the digital current sensor 507, the temperature and humidity detector 508, the infrared monitor 509, the four-way server 510 and the thermal airflow detector 511, the information monitored by the cabinet PDU intelligent monitoring system is more comprehensive, and the cabinet PDU intelligent monitoring system is ensured to be more effective when used.

[0036] Furthermore, since the wires are heated and current passes through them during use, and are used for a long time, the wires will be slightly worn, thereby affecting the accuracy of the cabinet PDU intelligent monitoring system. In this regard, in one embodiment, a two-way push rod 602 is fixedly installed at the bottom end of the mounting frame 6, and adjustment plates 603 are fixedly installed on both sides of the two-way push rod 602. The surfaces of the adjustment plates 603 are penetrated by limited position bolts 604, and connecting rods 605 are penetrated by both sides of the adjustment plates 603. Spherical bearings 606 are fixedly installed on both sides of the connecting rods 605. The surfaces of the spherical bearings 606 are sleeved with the cable tie 607, and guide wheels 608 are equidistantly installed inside the cable tie 607; micro pumps 703 are fixedly installed on both sides of the storage bottle 7, and shunt pipes 704 are fixedly installed on both sides of the micro pump 703. Serpentine pipes 705 are equidistantly installed on both sides of the shunt pipe 704, and nozzles 706 are fixedly installed on both sides of the serpentine pipe 705.

[0037] In addition, considering that it is used in a hot environment, the safety of the cabinet should be given more attention. In order to ensure that when a fire occurs, fire extinguishing work can be carried out at multiple angles and multiple levels in the cabinet, the fire can be quickly extinguished and the damage to the electrical equipment in the cabinet can be reduced. In this regard, in one embodiment, micro pumps 703 are fixedly installed on both sides of the storage bottle 7, and shunt pipes 704 are fixedly installed on both sides of the micro pump 703.

The surface of the serpentine pipe 705 is sleeved with sealing shaft sleeves 707. The heptafluoropropane fire extinguishing agent is stored through the storage bottle 7, and then when a fire occurs in the cabinet through the micro pump 703, the controller is set to When the internal temperature reaches degrees Celsius, the micro pump 703 is automatically turned on to extract the heptafluoropropane, and then the heptafluoropropane is divided into multiple strands for discharge through the shunt pipe 704, and the serpentine pipe 705 is used to facilitate the installation at multiple angles in the cabinet, and then the heptafluoropropane is sprayed through the nozzle 706 to extinguish the fire. After the heptafluoropropane is released, it does not contain particles or oil residues, and it is completely vaporized in the atmosphere without leaving any residue. It is non-conductive and will not damage electronic equipment during fire extinguishing. The sealing of the connection between the serpentine pipe 705 and the cabinet is increased through the sealing sleeve 707. Through the coordinated use of the micro pump 703, the shunt pipe 704 and the serpentine pipe 705, the cabinet can be extinguished at multiple angles and multiple levels, the fire can be quickly extinguished, and the damage of the fire to the electrical equipment in the cabinet can be reduced.

[0038] In order to ensure that the cabinet PDU intelligent monitoring system can continue to work and can continuously monitor intelligently, in one embodiment, a dual-axis motor 501 is fixedly installed at the bottom end of the fixing frame 5, screw rods 502 are fixedly installed on both sides of the dual-axis motor 501, and the surfaces of the screw rods 502 are sleeved with clamping plates 503, and a backup power supply 504 is fixedly installed at the bottom of the fixing frame 5.

Then, the screw rod 502 is driven to rotate by the dual-axis motor 501, thereby driving the clamping plate 503 to limit the detection equipment, and the cabinet can also be monitored by the backup power supply 504 when the external power supply stops supplying power.

[0039] In order to enable multiple devices to use the same signal and improve accuracy, in one embodiment, a wire diverter 601 is fixedly installed at the top of the interior of the mounting frame 6. The wire diverter 601 is installed through the mounting frame 6, and the wire diverter 601 is used to transmit an input signal to multiple output ports, so that multiple devices can use the same signal.

[0040] In order to achieve a better fire extinguishing effect, in one embodiment, a connecting pipe 701 is installed through the top of the storage bottle 7, and a pressure valve 702 is sleeved on the top of the connecting pipe 701.

Then, the heat dissipation holes 101 are set through the outer shell 1, which is convenient for the outer shell 1 to perform heat dissipation, and then the inspection cover 103 is installed by the screws 104.

[0041] In order to reduce the impact of weather on the cabinet PDU intelligent monitoring system, in one embodiment, a plurality of fixing bolts 201 are equidistantly installed on the top of the fixing base 2, and an audible and visual alarm 202 is fixedly installed between two adjacent fixing bolts 201.

Then, when the temperature in the cabinet reaches above 70 degrees Celsius, the audible and visual alarm 202 sounds an alarm to remind the staff to perform emergency cooling of the cabinet. The meaning of 70 degrees Celsius here is: although 70 degrees Celsius is not the ignition point of most materials, this temperature can still cause thermal decomposition of the wires and release flammable gases, thereby causing a fire under appropriate conditions. Therefore, 70 degrees Celsius is selected here.

[0043] The working principle and use process of the present invention:

[0044] By setting a stress monitoring module on the cable tie buckle, an image drawn according to stress and tightening force is preset in the control terminal. When the stress changes, the tightening force at this time must also change accordingly. If the stress increases, the corresponding tightening force must be reduced, so that the stress can be reduced again. The stress monitoring module is used to monitor the stress of the wires at the cable bundle and upload the monitored data to the control terminal. The control terminal compares the data of the stress monitoring module with the image drawn according to stress and tightening force preset in the control terminal. The control terminal controls the cable tie module to adjust the tightening force of the wire to reduce the mechanical stress at the wire bundling location, which solves the problem in the prior art that the wire expands due to heat, and the position where the cable tie buckle binds and fixes the wire limits the change in the length of the wire, resulting in mechanical stress at the position where the wire is bundled and fixed.
