When the A microswitch is closed, the control module 14 end of the IC3 is lowered to low level, and the control module IC3 judges that the grounding rod needs to be sent in. Meanwhile, the control module IC3 judges whether the output signals of the three-phase high-voltage electrification detection circuit are electrified at the 10, 11 and 12 ends, if the electrification is detected, the operation is refused, and the operation is informed through the IC5 voice module.

When the reading is the same as the code of the wireless receiving module IC6, the port 18 of the control module IC3 goes low, the control IC4 stops the motor driving module driving motor M, and the IC3 control module 21 port controls the IC5 to inform the voice module. The ground rod is installed in place. If the IC3 control circuitry reads the ground bar code. When the code of the wireless receiving module IC6 is different, the port 18 of the IC3 control module is changed into low level and the port 19 of the IC3 control module is changed into high level, so that the control IC4 motor driving module drives the motor M to reversely rotate, the gear on the motor shaft rotates to drive the rack at the bottom of the grounding rod to move outwards until the grounding rod is pushed out, when the state detection switch A is disconnected, the port 14 of the IC3 control module is changed into high level, the port 19 of the IC3 control module is changed into low level, the control IC4 motor driving module stops the motor M from rotating, and meanwhile, the port 21 of the IC3 control module controls the IC5 voice module to inform. The ground rod does not match the reality. The installation is denied.

The voice module and the single chip microcomputer communicate in a pulse triggering mode through a two-wire serial port control mode. The single chip microcomputer sends data through a CLK clock and a DI data line to control the module. The single chip microcomputer sends 16-bit audio addresses to trigger corresponding audio. The audio address (0x0001-0x0E00), AD4 alarm voice response audio file are stored under the root directory on the TF card, and the audio file named by the return value is put in. The loudspeaker is driven from the output end of the programming voice module, and the voice alarm grounding rod is arranged on the address voice signal corresponding to each bit audio frequency address, as shown in figure 8

When an operator installs a grounding wire, the handheld terminal is applied to an off-line microcomputer grounding wire manipulator system, the computer five-prevention operating system transmits grounding wire installation equipment and a coding signal to the grounding wire manipulator, the operator clicks a corresponding equipment button on the handheld terminal before walking to the installation equipment, and the operation instruction is equivalent to an operation instruction and is transmitted to a grounding pile in a wireless transmitting mode. The grounding pile wireless receiving module IC6 receives the installation grounding wire coding signal, and stores the signal into the internal memory after processing. The operating personnel holds the earth bar handle, inserts the earth bar in earth pile front earth bar jack. The detection switch A is closed, the control module 14 end of the IC3 is lowered to low level, and the control module IC3 judges that the grounding rod needs to be sent. Meanwhile, the control module IC3 judges whether the output signals of the three-phase high-voltage electrification detection circuit are electrified at the 10, 11 and 12 ends, if the electrification is detected, the operation is refused, and the operation is informed through the IC5 voice module. Three-phase high voltage is charged.
If the electrification is not detected, the port of the IC3 control module 18 outputs high level, the control IC4 motor driving module drives the motor M to rotate forwards, the gear on the motor shaft rotates to drive the rack at the bottom of the grounding rod to move inwards, the micro switch B is pressed down after the grounding rod is in place, when the micro switch B is closed, the end of the IC3 control module 15 is lowered to low level, and the control module IC3 judges that the grounding rod is in place. Meanwhile, a coding circuit interface at the front end of the ground rod is communicated with an internal main circuit, and a control circuit reads the code of the ground rod. When the reading is the same as the code of the wireless receiving module IC6, the port 18 of the control module IC3 goes low, the control IC4 stops the motor driving module driving motor M, and the IC3 control module 21 port controls the IC5 to inform the voice module. The ground rod is installed in place. If the IC3 control circuitry reads the ground bar code. When the code of the wireless receiving module IC6 is different, the port 18 of the IC3 control module is changed into low level and the port 19 of the IC3 control module is changed into high level, so that the control IC4 motor driving module drives the motor M to reversely rotate, the gear on the motor shaft rotates to drive the rack at the bottom of the grounding rod to move outwards until the grounding rod is pushed out, when the state detection switch A is disconnected, the port 14 of the IC3 control module is changed into high level, the port 19 of the IC3 control module is changed into low level, the control IC4 motor driving module stops the motor M from rotating, and meanwhile, the port 21 of the IC3 control module controls the IC5 voice module to inform. The ground rod does not match the reality. The installation is denied.
As shown in fig. 9, when the grounding wire is detached, an operator clicks a corresponding device button on the handheld terminal, which is equivalent to an operation instruction, and transmits the operation instruction to the grounding pile in a wireless transmission manner. When the grounding pile receives correct codes and instructions, the motor driving module drives the motor M to rotate reversely, and the grounding rod is pushed out. The intelligent grounding device is realized, 1. when the grounding wire installation coded signal of the operation task is not transmitted to the grounding pile, and the grounding rod is forcibly installed, the grounding pile device can automatically withdraw the grounding rod and warn by voice; 2. the ground rod is installed and the codes in the ground pile are different, the ground pile device can automatically withdraw the ground rod and warn by voice; 3. when the grounding rod is installed, any one phase of bus is electrified to be detected, the grounding pile device can automatically withdraw the grounding rod, and voice warning is given; the potential hazards of serious accidents of artificial misassembly, misdisassembly and missed disassembly caused by artificial negligence and power transmission with a grounding wire are eliminated; therefore, the current situation that the installation of the grounding wire depends on a system to prevent errors is changed, the labor intensity of manual judgment of operators is reduced, the grounding wire of the whole maintenance work is monitored, the information interaction between the grounding wire and the operators is realized, and the operation management of the temporary grounding wire is effectively improved. The work efficiency of operation maintainer is improved, the security of electric power system operation has been ensured, and after closing switch cabinet door, the device power self-closing.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; it is obvious as a person skilled in the art to combine several aspects of the invention. And such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
