For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a signal connection system provided by the present invention, where the signal connection system includes a JTAG (Joint Test Action Group, joint test working group) connector, a power supply 2, a first protection circuit 3 formed by connecting a first fuse device 31 and a first control switch 32 in series, and a processor 4;
the output end of the power supply 2 is respectively connected with one end of the first protection circuit 3 and the first monitoring end of the processor 4, the other end of the first protection circuit 3 is connected with the first end of the power supply terminal of the JTAG connector 1, the second end of the power supply terminal of the JTAG connector 1 is used for being connected with the power supply 2 end of the burner, the first end of the signal terminal of the JTAG connector 1 is connected with the chip to be burned, and the second end of the signal terminal of the JTAG connector 1 is used for being connected with the signal output end of the burner;
the JTAG connector 1 is used for realizing JTAG signal connection between the chip to be burned and the burner;

wherein the default state of the first control switch 32 is the closed state.
Specifically, in view of the technical problem in the background art, in combination with consideration of the possibility that a wiring error necessarily exists when the burner is connected with the JTAG connector 1 through the cable, once the ground terminal of the burner is connected to the power supply terminal of the JTAG connector 1, damage to the burner and the power supply 2 is likely to occur, so in the present application, the first fusing device 31 is arranged in the loop, so that the circuit breaking is automatically realized when the ground terminal of the burner is connected to the power supply terminal of the JTAG connector 1, on this basis, the present application also additionally controls the first control switch 32 to be opened when the voltage abnormality of the power supply 2 is monitored through the processor 4, thereby realizing the circuit breaking control, preventing the first fusing device 31 from not normally being opened, and because the present application has a dual circuit breaking protection mechanism, the reliability of circuit breaking protection is greatly improved, thereby preventing the wiring error from damaging the burner and even the power supply 2 to the greatest extent, the maintenance cost is reduced, and the working efficiency is improved.
Specifically, the JTAG connector 1 is used because the burner needs to communicate with the chip to be burned through the JTAG interface in the normal case, and the JTAG connector 1 can provide JTAG interface for the burner and the chip to be burned and realize the data communication of the burner and the chip to be burned.
Of course, in addition to the JTAG connector 1, connectors having other interface forms may be provided based on writers having different interface requirements, and the embodiment of the present invention is not limited herein.

In the embodiment of the present invention, the first control switch 32 is additionally disposed in the loop where the pin of the power supply 2 is located, the processor 4 may monitor whether the voltage of the power supply 2 is normal through the first detection end to determine whether to disconnect the first control switch 32, and under normal conditions, the voltage value should be a standard value (for example, 3.3V), if the processor 4 finds that the deviation is large, for example, when the power supply 2 is grounded due to a wiring error and generates instantaneous high voltage (possibly causing damage to related devices), the first control switch 32 may be controlled to disconnect, so as to realize circuit breaking protection, and the two circuit breaking protection mechanisms are redundant, and meanwhile, the possibility of failure is extremely low, thereby improving safety.
The serial connection sequence of the first fusing device 31 and the first control switch 32 in the circuit can be arbitrarily selected, and the embodiment of the present invention is not limited herein.
