[0036] In this embodiment, the digital display of the propulsion speed 080 can display the current real-time propulsion speed, and the grouting operator can adjust the grouting pressure and the number of grouting routes according to the propulsion speed.

The receiver communication indicator light 200 displays the communication status between the wireless grouting receiver 020 and the PLC controller 030. When the communication is abnormal or not connected, the receiver communication indicator light 200 lights up red. When the communication is normal, the receiver communication indicator light 200 lights up green. The receiver fault indicator light 210 is used to display the working fault of the wireless grouting receiver 020. When the wireless grouting receiver 020 cannot communicate with the wireless grouting remote control 010 or the wireless grouting receiver 020 communicates abnormally with the PLC controller 030, the receiver fault indicator light 210 lights up red. When the wireless grouting receiver 020 is working normally, the receiver fault indicator light 210 does not light up.

[0044] In a possible embodiment, when the grouting pressure PID adjustment is automatically performed, the knob 050 is first adjusted to adjust the knob signal transmitted from the wireless grouting remote controller 010 to the wireless grouting receiver 020, so that the PLC controller 030 receives the data of the adjustment knob 050 received by the wireless grouting receiver 020. The PLC controller 030 processes the data transmitted by the grouting pressure sensor and the data of the adjustment knob 050 through PID, so that the PLC controller 030 outputs the control voltage and outputs the current after the amplifier board processes it. The proportional valve of the currently selected grouting pump receives the input current of the amplifier board, and then adjusts the grouting pressure of the current grouting route. The data is transmitted to the PLC controller 030 through the network cable socket of the wireless grouting receiver 020 through the wireless grouting receiver 020, and the PLC controller 030 gives a voltage to allow the amplifier board channel to work, and then the analog output voltage of the PLC controller 030 corresponds to the output current of the amplifier board. Grouting PID control transmits the pressure data to the wireless grouting remote controller 010 through the wireless grouting receiver 020 according to the grouting pressure sensor data received by the PLC controller 030, so that the grouting pressure digital display 060 on the wireless grouting remote controller 010 displays the received pressure data. The operation mode switching lever 070 switches the automatic or manual control mode of the currently selected grouting pump, and transmits the lever signal to the PLC controller 030 through the wireless grouting receiver 020. The grouting PID control can only be started in the automatic mode.

[0045] It should be emphasized that the PID control program in the PLC controller 030 uses a conventional analog PID algorithm to adjust K P , K D , K i , so that the PLC controller 030 adjusts the output current of the amplifier board to control the grouting proportional valve to adjust the movement speed of the grouting cylinder, so that the pressure in the pipeline reaches the set pressure target value and stabilizes near the adjusted set value.

[0046] In summary, the grouting pressure digital display 060 of the utility model can display the grouting pressure of the currently selected grouting route. The mode switching lever 070 can switch the automatic or manual control mode of the currently selected grouting pump.

The propulsion speed digital display 080 can display the current real-time propulsion speed, and the grouting operator can adjust the grouting pressure and the number of grouting routes according to the propulsion speed. At the same time, the grouting operator can turn the mortar tank water adding lever 090 to control the water adding ball valve to open or close according to whether water needs to be added to the mortar tank.

The PLC controller 030 gives a voltage to allow the amplifier board channel to work, and then the analog output voltage of the PLC controller 030 corresponds to the output current of the amplifier board.Grouting PID control transmits the pressure data to the wireless grouting remote controller 010 through the wireless grouting receiver 020 according to the grouting pressure sensor data received by the PLC controller 030, so that the grouting pressure digital display 060 on the wireless grouting remote controller 010 displays the received pressure data. The operation mode switching lever 070 switches the automatic or manual control mode of the currently selected grouting pump, and transmits the lever signal to the PLC controller 030 through the wireless grouting receiver 020.
