[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 2 As shown, a fault early warning method for an electromechanical control system is proposed:

[0037] S1: Place the corresponding number of early warning modules next to the electromechanical control system;

[0038] S2: When the temperature generated by the operation of the electromechanical control system exceeds the warning temperature (warning temperature ≥ 29.76℃, normal operating temperature of the electromechanical control system 18℃-25℃), the warning module issues a warning signal, and the sound collection module receives the warning signal at this time.

[0039] S3: After receiving the warning sound from the warning module, the sound collection module will transmit the signal to the central processing unit module, which will then notify the staff to troubleshoot the problem.

[0040] The specific warning signal proposed in S2 is that when the ambient temperature exceeds the warning temperature (29.76℃), the fixing block 17 located inside the container 16 will melt, causing the fixing block 17 to lose its fixation to the connecting rope 18, thereby causing the first rotating rod 11 to rotate, and causing the collision ball 14 on the first rotating rod 11 to continuously strike the spring piece 15 to make a sound.

[0041] like Figure 1 As shown, an electromechanical control system fault early warning system is disclosed; the system includes a central processing unit module, a power supply module, an early warning module, and a sound collection module;

[0042] The central processing unit module and the sound collection module are connected via a signal;

[0043] The early warning module and the sound collection module are connected via a signal;

[0044] The power module supplies power to the central processing unit module and the sound collection module;

[0045] The sound collection module can collect nearby sound signals and send them to the central processing unit module;

[0046] The central processing unit module can process the information sent by the sound collection module.

[0047] like Figure 3 , Figure 4 and Figure 6 As shown, the device is applicable to a fault early warning system for an electromechanical control system as proposed in claim 3; the early warning module includes an early warning box 1; a first rotating rod 11 is rotatably connected inside the early warning box 1; a torsion spring is installed at the connection between the first rotating rod 11 and the early warning box 1; a pair of fixing rings 12 are fixedly connected to the middle of the first rotating rod 11; a pair of connecting rods 13 are fixedly connected to the surface of the fixing rings 12; a collision ball 14 is fixedly connected to the end of the connecting rod 13; several spring pieces 15 are fixedly connected to the top and bottom of the inner side of the early warning box 1; the spring pieces 15 correspond to the positions of the collision balls 14; a holding box 16 is fixedly connected to the bottom of the inner side of the early warning box 1; a fixing block 17 is fixedly connected inside the holding box 16; a connecting rope 18 is fixedly connected to the middle of the fixing block 17; one end of the connecting rope 18 is fixedly connected to the middle of the first rotating rod 11. During operation, the fixing block 17 placed inside the holding box 16 is made of gallium metal (melting point 29.76℃), and the normal operating temperature of the electromechanical equipment is 18℃-2℃. When the ambient temperature of the electromechanical equipment reaches 30℃-40℃, it is easy for the electromechanical equipment to malfunction and be damaged. With the setting of the warning box 1, when the temperature around a certain electromechanical equipment exceeds the melting point of the fixing block 17, the fixing block 17 will melt and become liquid, thus losing its fixation to the connecting rope 18. At this time, under the action of the torsion spring, the first rotating rod 11 will roll back and rotate, causing the collision ball 14 to rotate, causing the collision ball 14 to continuously strike the spring 15 and make a sound. At this time, the sound collection module will collect the sound generated in the area and then send the warning signal to the central processing unit module for processing. This step, by setting multiple warning boxes 1, can detect the dispersed electromechanical control cabinets. When the control system inside a certain control cabinet heats up, the above-mentioned warning module will issue a warning, so that the central processing unit module can receive the warning signal and then notify the staff to check the system, reduce the occurrence of faults, and improve the safety of the electromechanical control system during operation.

[0048] like Figure 5As shown, an oxygen box 2 is fixedly connected to the inner wall of the warning box 1; a cover 21 is hinged to the top of the oxygen box 2; a through hole 22 is opened in the middle of the oxygen box 2; a breathable mesh 23 is fixedly connected inside the oxygen box 2; one end of the connecting rope 18 away from the first rotating rod 11 passes through the through hole 22 and is fixedly connected to the top side wall of the cover 21. During operation, when the electromechanical system experiences a high-temperature fault, it usually causes the equipment to burn and a fire to occur. By pre-placing oxygen absorber inside the oxygen box 2, when the fixing block 17 melts, the first rotating rod 11 pulls the connecting rope 18 to rewind, thereby pulling the cover 21 to allow the oxygen absorber inside the oxygen box 2 to come into contact with the air, reducing the oxygen content around the electromechanical system. This step reduces the oxygen content around the high-temperature control system, reducing the possibility of combustion caused by the electromechanical system heating up too quickly, and further reducing the possibility of faults occurring during the operation of the electromechanical control system.

[0049] like Figures 5 to 7 As shown, a sealing strip 3 is fixedly connected to the side wall of the cover 21; multiple sets of first magnets 31 are fixedly connected to the side wall of the sealing strip 3; multiple sets of grooves 32 are opened on the side wall of the oxygen box 2; a second magnet 33 is fixedly connected inside the groove 32; the second magnet 33 corresponds to the first magnet 31 and is attracted to each other. During operation, when the cover 21 is placed on the oxygen box 2, the mutual attraction between the first magnet 31 and the second magnet 33 seals the connection between the sealing strip 3 and the cover 21, reducing the loss of oxygen agent from contact with air under normal conditions.

[0050] like Figure 3 and Figure 5 As shown, a pair of first synchronous pulleys 4 are fixedly connected to the middle of the first rotating rod 11; a second rotating rod 41 is rotatably connected to the inner side wall of the warning box 1; the second rotating rod 41 penetrates the side wall of the oxygen box 2 and is rotatably connected to the oxygen box 2; a pair of second synchronous pulleys 42 are fixedly connected to the middle of the second rotating rod 41; a synchronous belt 43 is installed between the first synchronous pulley 4 and the second synchronous pulley 42; several connecting plates 44 are fixedly connected to the middle of the second rotating rod 41; the connecting plates 44 are located inside the oxygen box 2. During operation, when the first rotating rod 11 rotates, the second rotating rod 41 rotates simultaneously under the drive of the synchronous belt 43, causing the connecting plates 44 to flip the oxygen absorber inside the oxygen box 2, so that the oxygen absorber comes into full contact with the air, quickly reducing the oxygen content around the electromechanical control system and reducing the possibility of combustion.

[0051] like Figure 3 and Figure 4 As shown, a pair of ventilation holes 5 are provided on the side wall of the warning box 1; a pair of fan blades 51 are fixedly connected to the middle of the second rotating rod 41. When working, the second rotating rod 41 is rotated to drive the ventilation holes 5 to rotate, thereby accelerating the exchange of air between the warning box 1 and the outside air and reducing the oxygen content in the outside.

[0052] like Figure 3 As shown, a dustproof net 6 is fixedly connected to the middle of the ventilation hole 5. During operation, by providing a dustproof net 6 on the ventilation hole 5, the entry of external dust into the warning box 1 during air exchange can be reduced, thus reducing the problem of difficulty in cleaning.

[0053] During operation, the fixing block 17 inside the holding box 16 is made of gallium metal (melting point 29.76℃). The normal operating temperature of the electromechanical equipment is 18℃-25℃. When the ambient temperature of the electromechanical equipment reaches 30℃-40℃, it is prone to failure and damage. Through the setting of the warning box 1, when the temperature around a certain electromechanical device exceeds the melting point of the fixing block 17, the fixing block 17 will melt and become liquid, thus losing its fixation to the connecting rope 18. At this time, under the action of the torsion spring, the first rotating rod 11 will rewind and rotate, causing the collision ball 14 to rotate, causing the collision ball 14 to continuously strike the spring 15 and produce a sound. At this time, the sound collection module will collect the sound generated in this area and then send the warning signal to the central processing unit module for processing. When the electromechanical system experiences a high temperature fault, it will usually trigger the equipment. In the event of combustion or fire, oxygen absorber is pre-placed inside the oxygen box 2. When the fixing block 17 melts, the first rotating rod 11 pulls the connecting rope 18 to rewind, thereby pulling the cover 21 to allow the oxygen absorber inside the oxygen box 2 to come into contact with the air, reducing the oxygen content around the electromechanical system. When the cover 21 is placed on the oxygen box 2, the mutual attraction between the first magnet 31 and the second magnet 33 seals the connection between the oxygen box 2 and the cover 21 with the sealing strip 3. When the first rotating rod 11 rotates, the second rotating rod 41 rotates simultaneously under the drive of the synchronous belt 43, causing the connecting plate 44 to flip the oxygen absorber inside the oxygen box 2, allowing the oxygen absorber to come into full contact with the air. The rotation of the second rotating rod 41 causes the ventilation hole 5 to rotate, accelerating the exchange of air between the warning box 1 and the outside air.
