The input of the circuit protection controller 15 is connected to a short - circuit detection sensor 16. The working principle of the short - circuit detection sensor is usually based on the change of current or voltage to detect the short - circuit situation in the circuit. When the current in the circuit suddenly increases or the voltage decreases abnormally, the sensor will sense this change and generate a corresponding signal. The input of the circuit protection controller 15 is connected to a current sensor 17. A current sensor is a detection device that can sense the information of the measured current and can transform the detected information into an electrical signal or other required form of information that meets certain standard requirements according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording, and control. The input of the circuit protection controller 15 is connected to a voltage sensor 18. A voltage sensor is a device used to measure voltage, usually used to monitor and control the voltage in the circuit. It usually consists of an induction part and a conversion part. The induction part is used to sense the voltage in the measured circuit, and the conversion part converts the sensed voltage into an available output signal. The input of the circuit protection controller 15 is connected to a temperature sensor 19. A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. It can be divided into two categories: contact type and non - contact type according to the measurement method, and can be divided into two categories: thermal resistance and thermocouple according to the sensor material and electronic component characteristics. The output of the circuit protection controller 15 is connected to a circuit switch 20. The input of the circuit protection controller 15 is connected to a staff contact information memory 21. The output of the circuit protection controller 15 is connected to a GSM module 22. The GSM module integrates a GSM radio frequency chip, a baseband processing chip, a memory, a power amplifier device, etc. on a circuit board, and has an independent operating system, radio frequency processing, baseband processing, and can complete the encoding, decoding, sending, and receiving of radio frequency signals and audio signals.The output end of the GSM module 22 is connected to the mobile phone end 23; The short-circuit detection sensor 16 is used to detect whether the wire 2 of the industrial robot is short-circuited, and transmits the detection result to the line protection controller 15 for processing; The current sensor 17 is used to detect the current of the wire 2 of the industrial robot, and transmits the detection result to the line protection controller 15 for processing; The voltage sensor 18 is used to detect the voltage of the wire 2 of the industrial robot, and transmits the detection result to the line protection controller 15 for processing; The temperature sensor 19 is used to detect the temperature of the wire 2 of the industrial robot, and transmits the detection result to the line protection controller 15 for processing.

[0020] The voltage value display screen 5 is arranged between the current value display screen 4 and the temperature value display screen 6.

[0021] The line protection controller 15 is set as a single-chip microcomputer. A single-chip microcomputer is an integrated circuit chip, which integrates a central processing unit CPU with data processing capabilities, a random access memory RAM, a read-only memory ROM, multiple I / O ports, an interrupt system, a timer / counter and other functions onto a silicon chip to form a small and complete microcomputer system.

[0022] The output end of the line protection controller 15 is connected to the input end of the short-circuit warning lamp 7, and the output end of the line protection controller 15 is connected to the input end of the line normal warning lamp 8.

[0023] The output end of the line protection controller 15 is connected to the input end of the current anomaly warning lamp 9, and the output end of the line protection controller 15 is connected to the input end of the current normal warning lamp 10.

[0024] The output end of the line protection controller 15 is connected to the input end of the voltage anomaly warning lamp 11, and the output end of the line protection controller 15 is connected to the input end of the voltage normal warning lamp 12.

[0025] The output end of the line protection controller 15 is connected to the input end of the temperature anomaly warning lamp 13, and the output end of the line protection controller 15 is connected to the input end of the temperature normal warning lamp 14.

[0026] The model of the single-chip microcomputer is set as M68HC16, the model of the short-circuit detection sensor 16 is set as LG-WCS1700, the model of the current sensor 17 is set as LA-80, the model of the voltage sensor 18 is set as LV28-P, the model of the temperature sensor 19 is set as DS18B20, and the model of the GSM module 22 is set as SIM800.

[0027] The implementation mode is specifically as follows: When using the present invention, the short-circuit detection sensor 16 can detect whether the industrial robot wire 2 is short-circuited, and transmit the detection result to the line protection controller 15 for processing. The current sensor 17 can detect the current of the industrial robot wire 2, and transmit the detection result to the line protection controller 15 for processing. The voltage sensor 18 can detect the voltage of the industrial robot wire 2, and transmit the detection result to the line protection controller 15 for processing. The temperature sensor 19 can detect the temperature of the industrial robot wire 2, and transmit the detection result to the line protection controller 15 for processing. The measured current, voltage and temperature can be respectively displayed on the current value display screen 4, voltage value display screen 5 and temperature value display screen 6. When the short-circuit detection sensor 16, current sensor 17, voltage sensor 18 and temperature sensor 19 detect abnormalities, the abnormal indicator lights at the corresponding positions will light up. If normal, the normal indicator light will light up. For example, when the voltage is abnormal, the voltage normal indicator light 12 will turn off and the voltage abnormal indicator light 11 will light up. At the same time, the line protection controller 15 controls the line switch 20 to cut off the industrial robot wire 2, so that the industrial robot wire 2 is no longer powered on, avoiding serious problems. Meanwhile, the line protection controller 15 sends information to the mobile phone 23 of the staff through the GSM module 22, so that the staff can arrive in time to handle the problem of the industrial robot wire 2. This enables the present invention to notify the staff to handle the problem in time when encountering short-circuit, overvoltage, overcurrent, overheat conditions, and can cut off the power in time, significantly reducing the damage probability of the industrial robot, thus greatly improving the use safety of the industrial robot and making the actual use effect of the present invention better.
