The measurement and control mechanism 1, at this time, the moving measurement and control mechanism 1 will drive the partial structure of the auxiliary mechanism 2 (except the rectangular groove 208, the rectangular hole 211, the screw hole 213 and the rectangular block 207) to move. When the end of the shell 104 close to the mounting hole 106 moves to the box opening of the embedded box, the measurement and control mechanism 1 continues to move. At this time, the shell 104 will first enter the interior of the box, and then the partial structure of the auxiliary mechanism 2 will also enter the interior of the box in turn, and then the shell cover 101 and the measurement and control assembly 102 will also enter the interior of the box in turn. When the shell cover 101 is about to complete the moving operation, it is rotated at the same time. The two hand-tightening rods 209 allow the two clamping blocks 214 to rotate 90 degrees, and then continue to move the shell cover 101 toward the inside of the box. When the two clamping blocks 214 pass through the corresponding clamping holes 212 and enter the corresponding rectangular holes 211, the hands applying the force to the two hand-tightening rods 209 are released, and the two clamping blocks 214 are reset and rotated back to the initial angle by using the cooperation of the two torsion springs 210, the two connecting blocks 201 and the two hand-tightening rods 209, so that the embedded device of the measurement and control device can be completed. When the measurement and control device needs to be suspended and installed, the two hand-tightening bolts 205 (such as Figure 4As shown), the upper mounting plate 203 is then moved. At this time, the moving mounting plate 203 will drive the U-shaped block 202 connected thereto to move. At the same time, the moving mounting plate 203 will also drive the multiple reinforcing strips 206 connected thereto to move. At the same time, the moving U-shaped block 202 will also drive the two porous plates 204 connected thereto to move in the corresponding plate grooves 215 respectively. When the mounting plate 203 moves up to a suitable position, the movement of the mounting plate 203 is stopped at this time, and then the two removed hand-tightening bolts 205 are installed back to the initial position, that is, the hand-tightening bolts 205 and the corresponding round holes on the porous plates 204 are matched to fix the porous plates 204 in the corresponding plate grooves 215. Then, the prepared screws, the upper mounting plate 203, the two porous plates 204, the two hand-tightening bolts 205, the two plate grooves 215 and the two connecting blocks 201 are matched to allow the measurement and control device to be suspended and installed. When the measurement and control device needs to be installed vertically, the two lower hand-tightening bolts 205 (as shown) are removed at this time. Figure 4As shown), the lower mounting plate 203 is then moved, and the moving mounting plate 203 will drive the U-shaped block 202 connected thereto to move, and the moving mounting plate 203 will also drive the multiple reinforcing strips 206 connected thereto to move, and the moving U-shaped block 202 will also drive the two porous plates 204 connected thereto to move inside the corresponding plate slots 215, respectively. When the mounting plate 203 moves down to a suitable position, the movement of the mounting plate 203 is stopped, and then the two removed hand-tightening bolts 205 are installed back to the initial position, that is, the hand-tightening bolts 205 are matched with the corresponding round holes on the porous plates 204 to fix the porous plates 204 inside the corresponding plate slots 215, and then the prepared screws, the upper mounting plate 203, and the two porous plates 20 4. The cooperation of two hand-tightening bolts 205, two plate grooves 215 and two connecting blocks 201 allows the measurement and control device to be installed vertically. When the measurement and control mechanism 1 needs to be assembled, the wires connecting the measurement and control assembly 102 are first passed through the wire holes on the perforated rubber plug 107 in sequence, and then the measurement and control assembly 102 is placed into the interior of the shell 104. Then, the shell cover 101 is covered and the position is adjusted until each control button and each indicator light on the measurement and control assembly 102 are respectively located in the corresponding through holes on the shell cover 101, and the display end of the measurement and control assembly 102 is also located in the observation hole 103. Then, the shell cover 101 and the shell 104 are fixed together with screws to complete the assembly of the measurement and control mechanism 1. When the measurement and control device is connected to an external power supply At this time, the user can input various preset parameters on the input module 63 in the human-machine interaction unit 6. At this time, the various parameter information input on the input module 63 will be displayed on the display module 61. At the same time, the various parameter information input on the input module 63 will also be transmitted to the control unit 5. When the control unit 5 receives the various parameter preset information, the control unit 5 will store it. Then, through the cooperation of the communication unit 8, the measurement and control device is wirelessly connected to the remote monitoring platform. Then, the measurement and control device is installed on the low-voltage circuit, and the cooperation of the human-machine interaction unit 6 and the control unit 5 is used to send a closing command to the closing module 72 on the execution unit 7. When the measurement and control device completes the closing operation, the measurement and control device can be operated on the low-voltage circuit. When the measurement and control device starts to be used on the low-voltage circuit, the voltage mutual inductance module 31 and the current mutual inductance module 32 on the data acquisition unit 3 will directly collect the voltage and current data of the low-voltage circuit, and directly convert the collected voltage and current data into digital signals through the A / D conversion module 33, and transmit them to the data processing and storage unit 4. Then the data processing and storage unit 4 will directly filter the received digital signal to remove interference and clutter, and calculate various electrical parameters after completing the filtering operation. Then the data processing and storage unit 4 will directly transmit the calculated various electrical parameters to the control unit 5, and will also store these electrical parameters, and will also directly communicate these electrical parameters through the cooperation of the communication unit 8.Wireless transmission to the remote monitoring platform, then the control unit 5 will directly compare the various data received with the corresponding preset parameters transmitted by the input module 63. When the various data received by the control unit 5 does not exceed the corresponding preset parameters transmitted by the input module 63, the control unit 5 will not send instructions to the execution unit 7, but will transmit the judgment result to the display module 61 and let the display module 61 display it. When the various data received by the control unit 5 exceeds the corresponding preset parameters transmitted by the input module 63, it means that the line is overloaded, short-circuited, etc. At this time, the control unit 5 will directly specify the disconnection to the execution unit 7, and the control unit 5 will also issue a fault information prompt to the alarm module 62, that is, the fault indicator light on the alarm module 62 will light up to remind the staff. When the execution unit 7 receives the disconnection instruction, the disconnection module 71 on the execution unit 7 will directly disconnect the measurement and control device from the low-voltage circuit. Then the execution unit 7 will directly transmit the execution result to the control unit 5. After that, the control unit 5 will transmit the execution result of the execution unit 7 to the remote monitoring platform through the cooperation of the communication unit 8 to remind the monitoring personnel in the monitoring room where the monitoring platform is located. ,
