The electric heating elements 1 can achieve heating when energized. Several sub-control cabinets 2 are directly installed on or near the vulcanizing machine 4. Each sub-control cabinet 2 contains an electric heating control unit 22, and each electric heating element 1 is electrically connected to one electric heating control unit 22. The electric heating control unit 22 controls the on / off state and real-time power of the electric heating element 1. A main control cabinet 3 is located next to the vulcanizing machine 4 in a convenient operating position. The main control cabinet 3 contains a main controller, which is electrically and communicatively connected to all the electric heating control units 22. The main controller can directly control the on / off state and power adjustment of the electric heating control units 22. The installation positions of each sub-control cabinet 2 and the main control cabinet 3 can be freely set according to space. The wiring between the sub-control cabinets 2 and the main control cabinet 3 is clear and flexible. The switching and heating temperature of each electric heating element 1 can be controlled by only one sub-controller 21 within a sub-control cabinet 2, thus placing some control elements within the sub-control cabinet 2, significantly reducing the size of the main control cabinet 3.

[0037] Furthermore, each of the sub-control cabinets 2 can also be equipped with a signal interaction unit 23. The temperature measuring element is set close to the electric heating element 1 to measure the temperature in real time. Each temperature measuring element is connected to a signal interaction unit 23 to realize signal transmission. The signal interaction unit 23 can collect the temperature information measured by the temperature measuring element. The main controller is connected to all the signal interaction units 23 to receive vulcanization setting information and complete information interaction, which can further reduce the volume of the main control cabinet 3.

[0038] Furthermore, several sub-control cabinets 2 may also be equipped with sub-controllers 21. The sub-controllers 21 are respectively connected to the main controller, the electric heating control unit 22 and the signal interaction unit 23. In actual use, the main controller is only used to set the preset temperature parameters and transmit them to the sub-controllers 21 in each sub-control cabinet 2. The sub-controllers 21 process and calculate independently, which can more conveniently control the on / off and power adjustment of the electric heating control unit 22.

Specifically, the display unit 24 and the operation unit 25 can be set as buttons and a display screen, respectively, or they can be integrated into a touch screen.

[0041] Furthermore, a human-machine interface device should be installed in a convenient location on the main control cabinet 3. This device can communicate or control the main controller inside the main control cabinet 3, facilitating the output of commands or the viewing of equipment status and other output information.

[0042] In this embodiment, please refer to Figure 1 The sub-controller 21 and the electric heating element 1, as well as the electric heating element 1 and the electric heating control unit 22, are all electrically connected by cables.

[0043] At the same time, please refer to Figure 1 The temperature measuring element and the signal interaction unit 23, as well as the main controller and the sub-controller 21, are all wired connections. Specifically, the wired connection is preferably implemented through a cable. In other embodiments, the temperature measuring element and the signal interaction unit 23, as well as the main controller and the sub-controller 21, can also be wireless communication connections.

[0045] Secondly, please refer to Figure 1 and Figure 4This invention provides an embodiment of a vulcanizing machine, comprising multiple vulcanizing chambers and a aforementioned electric heating vulcanizing machine control system. A control cabinet 2 is located on or near the vulcanizing chamber, while a main control cabinet 3 is located further away from the vulcanizing chamber than the control cabinets 2. The vulcanizing chamber contains a lower heating plate 41, an upper heating plate 42, a guide ring 43, and a patterned block 44. Multiple electric heating elements 1 are located on all or part of the lower heating plate 41, upper heating plate 42, guide ring 43, and patterned block 44. The lower heating plate 41, upper heating plate 42, guide ring 43, and patterned block 44 form the vulcanizing cavity. One or more electric heating control units 22 in the control cabinets 2 are connected to the electric heating elements 1. Simultaneous energization of the multiple electric heating elements 1 enables heating of the vulcanizing cavity. Temperature measuring elements are located close to the electric heating elements 1 to ensure accurate temperature measurement.

[0046] For any further explanation, please refer to [link / reference]. Figure 1 The number of electric heating elements 1 and the number of sub-control cabinets 2 are both set to three and correspond one-to-one. The three electric heating elements 1 are respectively set on the lower heating plate 41, the upper heating plate 42 and the guide ring 43. One sub-control cabinet 2 is set in the pit space below the vulcanizing chamber and corresponds to the electric heating element 1 on the lower heating plate 41.
