[0002] The three-phase smart energy meter data acquisition carrier communication technology is a technology that uses power lines as a communication medium to realize smart meter data acquisition and transmission. The application of this technology can realize data acquisition. Through carrier communication technology, the power consumption data of smart meters can be collected in real time, including voltage, current, power and other parameters; and in the existing public technology, the Chinese patent publication number CN116896398A discloses a power terminal data acquisition device based on carrier communication. This patent transmits the collected data to the acquisition control center module over a long distance through a pulse transmission module after modulation by a power carrier communication module. Therefore, the risk of acquisition failure or missed acquisition caused by environmental factors in the power terminal data acquisition process is greatly reduced, and the stability of power terminal data acquisition is improved. However, the acquisition communication device still has the following problems;

[0003] In the process of data acquisition and communication of three-phase smart energy meters, since it is necessary to acquire and communicate data such as line current and voltage, in order to prevent the current and voltage from being too large, there will be a current and voltage overload protector to protect the electrical appliances of the three-phase smart energy meter data acquisition and communication unit. Once the current and voltage data are abnormal and damage the current and voltage overload protector, the entire three-phase smart energy meter data acquisition and communication will not work normally, and it is necessary to wait for maintenance personnel to arrive at the scene. This results in a long interruption time for the acquisition and communication, and it is difficult to restore the three-phase smart energy meter data acquisition and communication in time. Therefore, a three-phase smart energy meter data acquisition and communication is needed. Summary of the invention

[0004] To this end, the present invention provides a three-phase smart electric energy meter data acquisition communication unit to solve the technical problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-phase smart energy meter data acquisition and communication unit, comprising an acquisition and communication housing, one side of the acquisition and communication housing is embedded and connected with an acquisition plug, and one side of the acquisition plug is installed with a disengagement switching mechanism; the disengagement switching mechanism comprises a main overload protector and an acquisition connector which are arranged equidistantly from left to right and are installed on one side of the acquisition plug, and the outer wall of the acquisition plug and the outer wall of the acquisition connector are fixedly connected with a connecting plate; a threaded sleeve is welded to the bottom end of each of the connecting plates, and a guide frame fixedly connected to the acquisition and communication housing is provided at the bottom end of the threaded sleeve, and a linkage screw which passes through two threaded sleeves is rotatably provided inside the guide frame, and a reduction motor for driving the linkage screw to rotate is fixedly installed on one side of the guide frame;

[0006] A positioning detection component is installed on the inner wall of the connecting plate;

[0007] A limit switch assembly is installed on the outer wall of the acquisition plug and located on one side of the acquisition communication shell. The acquisition plug is horizontally slidably connected along the inside of the acquisition communication shell, and the acquisition connector and the acquisition plug are horizontally slidably plugged with the main overload protector. The two connecting plates are symmetrically arranged, and the inner walls of the two threaded sleeves are threadedly connected to the outer wall of the linkage screw. The two threads on the outer wall of the linkage screw are opposite and symmetrically opened.

[0008] Preferably, a connecting wire and an acquisition communication chip are installed in sequence from right to left on the other side of the acquisition plug, a wireless controller fixedly connected to the acquisition communication shell is installed below the acquisition communication chip, and a carrier output plug is welded on one side of the acquisition communication chip and located above the connecting wire; the connecting wires are respectively welded to the acquisition plug and the acquisition communication chip, and a protective shell for protecting the acquisition communication shell is welded on one side of the carrier output plug, two detection terminals are plugged into the bottom end of the main overload protector, and a current and voltage detector for detecting the current and voltage of the main overload protector is installed at the bottom end of the detection terminals, a connecting block and an electric cylinder are installed in sequence from top to bottom on one side of the current and voltage detector, and the electric cylinder is respectively fixedly connected to the guide support frame and the connecting block.

[0009] According to the above technical solution, the inside of the main overload protector is detected by two detection terminals through a current and voltage detector. Once the current and voltage are abnormally excessive and damage the main overload protector, the two detection terminals are separated from the bottom of the main overload protector. At the same time, the wireless controller can remotely start the reduction motor to drive the linkage screw to rotate forward inside the guide support frame. The distance between the two threaded sleeves becomes larger, and at the same time, the distance between the two connecting plates becomes larger. The two connecting plates respectively drive the collection plug to separate from the main overload protector, and the collection connector is also separated from the main overload protector.

[0010] Preferably, the positioning detection assembly includes a spacing support block fixedly mounted on the inner wall of the connecting plate; a sensing end column and a spacing pressure sensor are provided on one side of the spacing support block from right to left in sequence, a distance sensor is installed on one side of the spacing pressure sensor, a connecting support block for supporting the distance sensor is provided at one end, two side-by-side limit columns are installed on one side of the connecting support block, a sleeve support plate is fixedly connected to the outer wall of the limit column and located at the top position of the guide support frame, an extrusion block and a separation pressure sensor are provided on one side of the sleeve support plate from right to left in sequence, one end of the extrusion block is fixedly connected to the two limit columns, and the other end of the extrusion block is fixedly connected to the sensing end of the separation pressure sensor, a support block is installed on one side of the separation pressure sensor, a guide slide bar for guiding the sliding of the sleeve support plate is provided on one side of the extrusion block, one end of the guide slide bar is fixedly connected to the support block, the support block is fixedly connected to the top of the guide support frame, and the vertical cross-sectional area of ​​one end of the guide slide bar is smaller than the vertical cross-sectional area of ​​the other end thereof.

[0011] According to the above technical solution, the connecting plate on the left drives the connecting support block to move left, the limiting column makes the sleeve support plate slide along the outer wall of the guide slide bar, and the limiting column makes the extrusion block squeeze on the separation pressure sensor, and the support block supports the separation pressure sensor. When the separation pressure sensor generates separation pressure, the reduction motor drive is turned off by the wireless controller, and the two connecting plates respectively drive the collection connector and the collection plug to be inserted into the internal positions on both sides of the standby overload protector. One connecting plate drives the interval support block to squeeze the sensing end column, and the other connecting plate drives the connecting support block to move. The connecting support block makes the interval pressure sensor squeeze the sensing end column. When the extrusion force generated by the interval pressure sensor is the same as the extrusion set by the wireless controller, and the distance data sensed by the distance sensor to the interval support block is the same, the reduction motor drive is turned off by the wireless controller.

[0012] Preferably, the limit switching assembly includes a guide frame plate slidably mounted on the outer wall of the acquisition plug and located at a position on one side of the acquisition communication shell, the guide frame plate is fixedly connected to the acquisition communication shell, one side of the guide frame plate is provided with a rotating shaft and a socket strip in sequence from the inside to the outside, a proximity sensor is fixedly connected to the inner wall of the socket strip and near its top end, one side of the socket strip is provided with a reduction switching motor for driving the rotating shaft to rotate, and the reduction switching motor is fixedly connected to the acquisition communication shell; a plurality of backup overload protectors are installed above the main overload protector, and one side of the backup overload protector is provided with a rotating bracket fixedly connected to the top of the main overload protector A switching shaft is welded on the inner wall of the rotating bracket, a linkage gear ring fixedly connected to the switching shaft is provided on one side of the rotating bracket, and a rotation connection is embedded between the switching shaft and the acquisition communication shell, a driving gear ring is meshed and transmitted on one side of the outer wall of the linkage gear ring, a driving reduction motor is embedded and installed on one side of the driving gear ring, the driving reduction motor is fixedly connected to the acquisition communication shell, the rotating shaft and the socket strip are integrally formed by die-casting, and the output end of the reduction switching motor is fixedly connected to the rotating shaft, and multiple spare overload protectors are fixedly connected to the rotating bracket, and multiple spare overload protectors are arranged in an arc with equal spacing.

[0013] According to the above technical solution, the driving reduction motor is started to drive the driving gear ring to rotate, and the driving gear ring drives the linkage gear ring to make the switching shaft rotate stably inside the acquisition communication shell, and the rotating bracket drives the other three backup overload protectors to move downward. When the main overload protector rotates to a position above the proximity sensor, the reduction switching motor is started to drive the rotating shaft to rotate the sleeve strip downward. After the sleeve strip can rotate the proximity sensor downward by ninety degrees, the reduction switching motor is turned off. When the backup overload protector continues to rotate downward and contacts the proximity sensor on the left side, the driving reduction motor is turned off by the wireless controller after being sensed by the proximity sensor to complete the precise rotation docking.

[0014] The present invention has the following advantages:

[0015] 1. The present invention adopts a disengagement switching mechanism so that when the current and voltage detector detects abnormal current and voltage damage of the main overload protector through the detection terminal, the reduction motor is started to drive the linkage screw to rotate forward inside the guide support frame, and the two connecting plates respectively drive the collection plug to separate from the main overload protector. After the collection connector is also separated from the main overload protector, the collection plug and the collection connector can be remotely and synchronously separated, and then the backup overload protector is switched on and the collection plug and the collection connector are synchronously connected to the backup overload protector. The backup overload protector can be automatically switched according to the damage of the main overload protector to restore the collection carrier communication. The collection communication interruption time is shorter, and the timeliness of restoring the collection communication line is effectively improved.

[0016] 2. The present invention utilizes a positioning detection component. When the acquisition plug and the acquisition connector are separated, the connection plate on the left drives the connection support block to move left, the limit column causes the sleeve support plate to slide along the outer wall of the guide slide bar, and the extrusion block is squeezed on the separation pressure sensor. After the separation pressure sensor generates separation pressure, the reduction motor drive is turned off by the wireless controller. When the acquisition plug and the main overload protector are docked with the backup overload protector, the connection support block causes the interval pressure sensor to squeeze the sensing end column. The extrusion force generated by the interval pressure sensor is the same as the extrusion value set by the wireless controller, and the distance data sensed by the distance sensor to the interval support block is the same. The reduction motor drive is turned off by the wireless controller, so that the backup overload protector can be accurately switched to the main overload protector position and the backup overload protector is in the same plane position as the acquisition plug and the acquisition connector. In this way, the accuracy of automatic switching is effectively improved, so the efficiency of restoring communication after accurate docking is effectively improved, avoiding large switching docking errors.

[0017] 3. The present invention drives the reduction motor to drive the driving gear ring to rotate through the limit switching component. When the main overload protector rotates to a position above the proximity sensor, the reduction switching motor is started to drive the rotating shaft to rotate the sleeve strip downward. The proximity sensor is located on the left side of the standby overload protector. The standby overload protector continues to rotate downward and generates an extrusion force when the left side contacts the proximity sensor. After the proximity sensor is sensed, the wireless controller turns off the driving reduction motor. The standby overload protector and the collection connector and the collection plug are at the same horizontal line position for precise docking of the standby overload protector. The docking is precisely switched, and the data acquisition communication of the three-phase smart energy meter is restored more timely.

[0018] Under the mutual influence of the above-mentioned multiple effects, first, the acquisition plug and the acquisition connector are synchronously separated from the main overload protector, and secondly, the extrusion force generated by the interval pressure sensor is the same as the extrusion value set by the wireless controller, and the distance data sensed by the distance sensor to the interval support block is the same, and finally, the proximity sensor is located at the left side of the backup overload protector and accurately docks the backup overload protector position. In summary, the damaged main overload protector can be accurately separated horizontally in time, and the backup overload protector can be accurately docked vertically and switched horizontally. The efficiency of switching the backup overload protector to replace the damaged main overload protector is effectively improved, and the acquisition communication can be restored more timely.

[0037] In this embodiment, as shown in the attached Figure 2-9 As shown, the limit switch assembly includes a guide frame plate 30 which is slidably mounted on the outer wall of the acquisition plug 2 and is located at one side of the acquisition communication housing 1.

[0038] The operation process of the data acquisition and communication unit of the three-phase intelligent electric energy meter of the present invention is as follows.

[0039] First, when the present invention collects communication, one end of the collection connector 4 is plugged into the main overload protector 3, and the other end of the collection connector 4 is connected to the collection harness, and the carrier output plug 13 can be connected to the output end of the three-phase smart energy meter. The line data, including current and voltage, are collected through the collection connector 4. The data is transmitted from the main overload protector 3 to the collection plug 2 through the collection connector 4, and the collection plug 2 is connected to the connecting line 10, and is transmitted to the collection communication chip 11 through the connecting line 10. The carrier is transmitted to the carrier output plug 13 through the collection communication chip 11, and the collected communication data is transmitted to the output end of the three-phase smart energy meter through the carrier output plug 13. The power line is used as a communication medium to realize the data collection and transmission of the smart meter.

[0040] Secondly, when the present invention is damaged and switched, the interior of the main overload protector 3 is detected by the current and voltage detector 16 through the two detection terminals 15. Once the current and voltage are abnormally large and damage the main overload protector 3, the internal fuse part is broken and damaged after the main overload protector 3 disconnects the circuit. The current and voltage of the main overload protector 3 are detected by the detection terminal 15 through the current and voltage detector 16. When the current and voltage of the main overload protector 3 are abnormal, the electric cylinder 18 can be started to drive the connecting block 17 to move the current and voltage detector 16 downward. The current and voltage detector 16 separates the two detection terminals 15 from the bottom of the main overload protector 3. At the same time, the wireless controller 12 can remotely start the reduction motor 9 to drive the linkage screw 7 to rotate forward inside the guide frame 8. The linkage screw 7 causes one threaded sleeve block 6 to move right along the guide frame 8 under the action of the thread, and the other threaded sleeve block 6 moves left along the guide frame 8. The distance between the two threaded sleeve blocks 6 becomes larger. At the same time, the distance between the two connecting plates 5 becomes larger. The two connecting plates 5 respectively drive the collection plug 2 to separate from the main overload protector 3.

[0041] The collection connector 4 is also separated from the main overload protector 3, and the left connecting plate 5 drives the connecting support block 23 to move leftward, and the connecting support block 23 squeezes and contacts two limiting columns 25, and the limiting columns 25 make the sleeve support plate 24 slide along the outer wall of the guide slide bar 28, and the limiting columns 25 squeeze the squeezing block 26 on the separation pressure sensor 27, and the separation pressure sensor 27 is supported by the support block 29. When the separation pressure sensor 27 generates separation pressure, the reduction motor 9 is driven by the wireless controller 12;

[0042] Then, when the limit switch of the present invention is performed, the support block on the acquisition communication housing 1 can play a reinforcing and supporting role for the driving reduction motor 40, and the driving reduction motor 40 is started to drive the driving gear ring 39 to rotate, and the driving gear ring 39 drives the linkage gear ring 38 to make the switching shaft 37 rotate stably inside the acquisition communication housing 1, and at the same time, the switching shaft 37 drives the rotating bracket 36 to rotate, and the rotating bracket 36 drives the main overload protector 3 to move up and rotate and separate from between the acquisition plug 2 and the acquisition connector 4, and at the same time, the rotating bracket 36 drives the other three standby overload protectors 35 to move downward, and when the main overload protector 3 rotates to a position above the proximity sensor 34, the start The dynamic reduction switching motor 32 drives the rotating shaft 31 to rotate the sleeve strip 33 downward. The sleeve strip 33 can rotate the proximity sensor 34 downward by ninety degrees, and then turn off the reduction switching motor 32. In this way, the proximity sensor 34 is located at the left side of the standby overload protector 35. When the standby overload protector 35 continues to rotate downward and contacts the left side of the proximity sensor 34, the wireless controller 12 turns off the driving reduction motor 40 after being sensed by the proximity sensor 34. The standby overload protector 35 is located in the gap between the collection connector 4 and the collection plug 2, and the standby overload protector 35, the collection connector 4 and the collection plug 2 are at the same horizontal line position;

[0043] Finally, when the present invention is docked and locked, the wireless controller 12 starts the reduction motor 9 to drive the linkage screw 7 to reverse inside the guide support frame 8, and the linkage screw 7 drives the two threaded sleeves 6 to approach each other under the action of the thread, and the two threaded sleeves 6 drive the two connecting plates 5 to approach each other, and the two connecting plates 5 respectively drive the acquisition connector 4 and the acquisition plug 2 to be inserted into the internal positions on both sides of the spare overload protector 35, and at the same time, one connecting plate 5 drives the interval support block 19 to squeeze the sensing end column 20, and the other connecting plate 5 drives the connection support block 23 to move, and the connection support block 23 causes the interval pressure sensor 21 to squeeze the sensing end column 20. When the extrusion force generated by the interval pressure sensor 21 is the same as the extrusion set by the wireless controller 12, and the distance data sensed by the distance sensor 22 to the interval support block 19 is the same, the reduction motor 9 drive is turned off by the wireless controller 12, and the acquisition plug 2 and the acquisition connector 4 can be connected with the spare overload protector 35 in a plug-in manner, and the acquisition communication function of the three-phase meter can be automatically and quickly restored without the maintenance personnel arriving at the site, and the data acquisition carrier communication function can be stably transmitted.

[0044] The model of the acquisition communication chip 11 is set to be a HZ6611 carrier communication chip, and the carrier communication rate is: 100Kbit / s to 12Mbit / s.
