Description

Technical Field

[0001] This invention relates to the field of electricity metering technology, specifically to a control system for preventing cross-connection of power lines. Background Technology

[0002] With urbanization and the continuous expansion of meter upgrades, electricity meters are now centrally located, resulting in complex wiring on-site. This makes wiring and meter installation errors common for on-site workers. Furthermore, limited manpower and environmental constraints make it difficult for workers to determine the correspondence between wiring lines and homeowners, hindering effective wiring checks and quality control. This leads to frequent instances of cross-connections between households. Cross-connections may be caused by incorrect wiring before or after the meter, or at switches, or by errors in customer registration information such as customer numbers and meter barcodes in the marketing system. These errors can trigger customer complaints, and if not handled properly, could have serious social consequences and damage the company's image. Summary of the Invention

[0003] This invention provides a power line anti-cross-household control system. During the wiring and meter installation phase, the system utilizes a pulse signal generator detachably connected to the meter connection end of the power line and a pulse signal receiver / feedback unit detachably connected to the household entry end of the power line. The power line itself transmits pulse signals from the meter connection end to the household entry end. The pulse signal receiver / feedback unit receives the pulse signal and then sends a feedback signal containing at least a user code identifier. The decoding module of the pulse signal generator decodes the received signal back into the user code, which is then displayed by the display module. This allows operators to intuitively, quickly, and accurately identify the power lines corresponding to different households, thus preventing wiring errors. It is particularly suitable for communities with numerous and complex centralized power meter wiring. This process utilizes the existing power lines themselves as an additional carrier for pulse signals during wiring and meter installation, not only making efficient use of on-site materials but also enabling rapid, accurate, and virtually error-free identification of the user corresponding to the power line.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A power line anti-cross-user control system includes a wiring anti-cross-user mechanism that detects the user corresponding to the power line before wiring. The mechanism includes a pulse signal generator detachably connected to the meter terminal of the power line and a pulse signal receiving feedback unit detachably connected to the power line entry terminal. The pulse signal receiving feedback unit has an input module and an encoding signal module. When the pulse signal receiving feedback unit is connected to the power line entry terminal, a user code is input through the input module, and the encoding signal module edits the user code into an electrical signal. The pulse signal generator has a decoding module and a display module. The pulse signal generator emits a pulse signal through the power line, and the pulse signal receiving feedback unit receives the pulse signal and sends a feedback signal in reverse. The feedback signal includes at least the electrical signal edited from the user code. The decoding module of the pulse signal generator decodes the received signal back into the user code and displays it through the display module, allowing the operator to confirm the user corresponding to the power line.

[0006] Using the above technical solution, both the pulse signal generator and the pulse signal receiver feedback unit have a pulse transmitting module and a quick-connect mechanism that can be detachably connected to the end of the wire; the pulse signal receiver feedback unit also has a plug that can be directly plugged into an indoor socket.

[0007] Using the above technical solution, the quick-connect mechanism includes a first insulating outer cylinder, a sliding conductive core disposed within the first insulating outer cylinder, and a claw also disposed within the first insulating outer cylinder and linked to the sliding conductive core for opening and closing; the claw includes multiple bases fixed to the inner wall of the first insulating outer cylinder and opening obliquely, and claw bodies respectively hinged to the bases; an elastic rope is stretched along the outer end of each claw body towards the base, causing the claw body to open outward under static force; a non-elastic rope is fixedly connected to the inner end of the claw body towards the sliding conductive core, causing the sliding core to open outward under static force. When the moving conductive core moves backward, it pulls the claw body to overcome the tension of the elastic rope and grip the wire inward; the outer circumference of the sliding conductive core is provided with multiple grooves spaced along its length; an insulating trigger is hinged to the first insulating outer cylinder by a torsion spring; the insulating trigger and the first insulating outer cylinder have a limiting structure so that it can only be activated in one direction; one end of the insulating trigger extends into the first insulating outer cylinder and can engage with the groove, and the other end extends out of the first insulating outer cylinder for operation; the sliding conductive core is engaged by the insulating trigger during its backward movement to prevent it from rebounding.

[0008] Using the above technical solution, the pulse signal generator also has a marking mechanism; the marking mechanism is located at the front end of the quick-connect mechanism and is coaxially arranged with the quick-connect mechanism. The marking mechanism includes a second insulating outer cylinder, an inner cylinder fixedly spaced within the second insulating outer cylinder, and multiple sets of ring frames fitted outside the inner cylinder; the multiple sets of ring frames are arranged parallel to each other, each set of ring frames includes ten frame positions, ten digital printing blocks are respectively embedded in the frame positions and can slide radially along the frame positions and return to their initial positions under the action of springs; a channel is opened on the inner cylinder along its length direction; a push rod mechanism driven by a linear motor is provided on the inner wall of the second insulating outer cylinder opposite to the channel; the push rod mechanism can push the digital printing blocks toward the axis and make the corresponding digital printing block pass through the channel and print on the outer surface of the wire insulation; each set of ring frames... The digital printing blocks of the body frame can print the numbers 0 to 9 at the end facing the axis; a gear shaft driven by a servo motor is also provided axially between the second insulating outer cylinder and the ring frame; multiple gears are sleeved on the gear shaft; the gears mesh with the outer gear rings provided on the outer ring of the ring frame; the gears include an inner ring and an outer ring; a bearing is sleeved between the inner ring and the outer ring; multiple piezoelectric ceramic blocks are arranged between the inner ring and the outer ring; an external circuit controls the piezoelectric ceramic blocks to turn on and off, and when energized, the piezoelectric ceramic blocks extend radially and simultaneously squeeze the inner ring and the outer ring, causing the inner ring and the outer ring to rotate in linkage; the marking mechanism also includes a controller, which receives the user code decoded and restored by the pulse electrical signal generator and controls the start and stop of the servo motor and the linear motor, and controls the energization of each piezoelectric ceramic block.

[0009] Using the above technical solution, the method for preventing cross-user communication using the wiring anti-cross-user mechanism includes the following steps:

[0010] ① Install the pulse electrical signal receiver feedback unit in each meter household to be wired, and connect it to the household socket through the quick-connect mechanism or directly through the plug; input the user code through the input module when installing each household;

[0011] ② Take the wire from the external centralized wiring meter, remove a section of insulation from the head, pass it through the marking mechanism, and insert it into the quick-connect mechanism of the pulse signal generator; the wire head moves the sliding conductive core backward under pressure, and the non-elastic rope pulls the claw body to overcome the elastic rope tension and grip the wire inward; during the backward movement of the sliding conductive core, it is locked by the insulating trigger to prevent rebound;

[0012] ③ The pulse transmitting module of the pulse signal generator transmits pulse signals to the wire through the sliding conductive core. The pulse signals are transmitted along the wire to the corresponding indoor pulse signal receiving feedback unit. After receiving the pulse signals, the pulse signal receiving feedback unit sends a feedback signal that contains at least the signal marked by the user code. The decoding module of the pulse signal generator decodes the received signal and restores it to the user code, which is then displayed by the display module.

[0013] ④ The controller of the marking mechanism receives the user code information transmitted by the pulse electrical signal generator and converts it into control information for the servo motor, linear motor, and external circuit. It controls the rotation of the servo motor and controls the power supply of each piezoelectric ceramic block through the external circuit. This controls the rotation of each ring frame by a certain angle through gears, so that the combination of digital printed blocks on each ring frame corresponding to the channel is consistent with the user code. Then, it controls the linear motor to move, and the linear motor drives the push rod mechanism to push the entire row of digital printed blocks to move towards the axis and pass through the channel to be printed on the outer surface of the wire insulation.

[0014] A power line anti-crossing control system further includes a post-connection anti-crossing mechanism, which includes a power supply circuit and a signal processor. One end of the power supply circuit is fixedly connected to an electricity meter A via a line. The terminals of electricity meter A are fixedly connected to an electricity meter B via a line. The terminals of electricity meter B are fixedly connected to a household appliance via a line.

[0015] The signal processor's terminals are fixedly connected to a signal receiver via a signal transmission line, and the signal receiver's terminals are fixedly connected to signal receiver A and signal receiver B via a signal transmission line.

[0016] A further improvement of the technical solution of the present invention is that: the line between the power supply circuit and the energy meter A is fixedly installed with the signal generator A, and the line between the energy meter B and the household appliance is fixedly installed with the signal generator B.

[0017] By adopting the above technical solution, the functions of electricity meter A and electricity meter B make it easier for users to observe their own electricity consumption and to determine whether there is cross-connection between their own lines, thus facilitating timely handling by users.

[0018] A further improvement of the technical solution of the present invention is that: the signal receiver A includes a signal generator body, one side of the outer wall of the signal generator body is fixedly installed to the terminal of the signal receiver through a signal transmission line, and insulating sleeves are snapped onto both ends of the signal generator body, and a fixing locking ring is overlapped on the outer wall of the insulating sleeve.

[0019] The insulating sleeve includes a first C-shaped retaining ring, the back of the outer wall of the first C-shaped retaining ring is engaged with one end of the signal generator body, and a second C-shaped retaining ring is engaged with the bottom of the first C-shaped retaining ring.

[0020] The fixing and locking ring includes a first locking plate and a second locking plate. The inner wall of the first locking plate overlaps with the bottom of the outer wall of the second C-shaped locking ring, and the inner wall of the second locking plate overlaps with the outer wall of the first C-shaped locking ring. A fixing plate is fixedly connected to the bottom of the outer wall of the first locking plate. Support seats are fixedly installed at the left and right ends of the fixing plate. A stud is slidably connected to the inner wall of the support seat, and a threaded locking cap is threadedly connected to the top of the stud.

[0021] By adopting the above technical solution, leakage at the connection between the signal generator body and the line can be avoided, thereby improving the safety of the line and making it easier to fix the signal generator on the wall.

[0022] A further improvement of the technical solution of the present invention is that: the first C-shaped retaining ring includes a rigid insulating rubber plate, the outer wall of the rigid insulating rubber plate overlaps with the inner wall of the second retaining plate, a soft insulating rubber plate is fixedly connected to the inner wall of the rigid insulating rubber plate, and a reinforcing insulating plate is fixedly connected to the front side of the soft insulating rubber plate.

[0023] By adopting the above technical solution, the cooperation between the rigid insulating rubber plate, the reinforced insulating plate, and the soft insulating rubber plate in the solution reinforces the internal structure of the first C-shaped retaining ring, thereby preventing the first C-shaped retaining ring from bending and deforming under the action of the fixing locking ring.

[0024] A further improvement of the technical solution of the present invention is that: an airbag plate is fixedly connected to the inner wall of the soft insulating rubber sheet, a wear-resistant insulating pressure plate is fixedly connected to the inner wall of the airbag plate, and a rubber insulating pressure strip is fixedly connected to the inner wall of the wear-resistant insulating pressure plate.

[0025] By adopting the above technical solution, the cooperation between the airbag plate, the wear-resistant insulating pressure plate, and the rubber insulating pressure strip in the solution increases the friction between the inner wall of the first C-shaped retaining ring and the outer wall of the line, thus avoiding the problem of excessive external force pulling the line out of the insulating sleeve.

[0026] A further improvement of the technical solution of the present invention is that: a second support spring is movably sleeved on the outer wall of the stud and located between the first and second clamping plates, and a first support spring is movably disposed in the inner cavity of the support seat.

[0027] By adopting the above technical solution, the cooperation between the second support springs in the solution facilitates the first and second clamping plates to press the outer wall of the insulating sleeve, avoiding the situation where the diameter of the insulating sleeve is too small and the inner parts of the first and second clamping plates cannot contact the outer wall of the insulating sleeve, thus affecting the installation effect of the signal generator.

[0028] A further improvement of the technical solution of the present invention is that: the second card plate includes a card plate body, the back of the card plate body is inserted into the outer wall of the stud, a wear-resistant plate is fixedly connected to the top of the card plate body, and a wear-resistant protrusion is fixedly connected to the top of the wear-resistant plate.

[0029] By adopting the above technical solution, the cooperation between the card plate body, wear-resistant plate, and wear-resistant protrusion in this solution increases the friction between the inner wall of the second card plate and the outer wall of the insulating sleeve, thus avoiding the problem of the insulating sleeve being pulled out of the inner cavity of the fixing locking ring.

[0030] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0031] 1. This invention provides a user wire anti-cross-connection control system. During the wiring and meter installation stage, a pulse signal generator detachably connected to the meter connection end of the wire and a pulse signal receiver / feedback unit detachably connected to the household entry end of the wire transmits pulse signals from the meter connection end to the household entry end using the wire itself. After receiving the pulse signal, the receiver / feedback unit sends a feedback signal in reverse, which includes at least a user code marker. The decoding module of the pulse signal generator decodes the received signal and restores it to the user code, which is then displayed by the display module. This allows operators to intuitively, quickly, and accurately determine the wires corresponding to different households, thus preventing wiring errors. It is very suitable for situations where there are many and complex wires in a centralized electricity meter system in a community. This process utilizes the existing wire itself as an additional carrier for transmitting pulse signals during wiring and meter installation, which not only makes efficient use of on-site materials but also enables quick, accurate, and virtually error-free determination of the user corresponding to the wire.

[0032] 2. This invention provides a user-controlled electrical wire anti-cross-connection system, employing a specially designed quick-connect mechanism. The effective electrical connection between the wire core and the pulse signal generator and pulse signal receiver feedback unit is achieved simply by inserting the wire. Simultaneously, it automatically and stably clamps the wire, thus achieving a stable electrical connection with a single, simple action. Releasing the connection requires only turning an insulated trigger; both forward and reverse operations are extremely simple and convenient. The quick-connect mechanism utilizes elastic and non-elastic ropes, combined with the movement of the sliding conductive core, to automatically open and close the claw for clamping and releasing. The slots, insulated trigger, and fiber mechanism efficiently and stably fix the position of the sliding conductive core, thereby securing the clamping state of the claw and ensuring the stability of the wire connection. The clamping state is released by rotating the insulated trigger, making operation extremely simple and convenient.

[0033] 3. This invention provides a user wire anti-cross-connection control system. It incorporates a marking mechanism that automatically, quickly, and accurately prints user codes on the wire insulation. Firstly, it effectively prevents operators from mistakenly connecting the wrong wire after the anti-cross-connection mechanism has identified the user. Secondly, the user code printed on the wire is permanently retained, allowing for direct identification of the corresponding user code during meter replacement, wiring modifications, and line inspections, thus facilitating long-term maintenance and future updates of the circuit system. The system utilizes multiple rotatable ring frames, each carrying printable number blocks from 0 to 9. A servo motor, gear shaft, and piezoelectric ceramic sheet are used to directly control the gear drive and stop via circuit switching. Each ring frame is precisely driven to rotate, and the corresponding number blocks at the designated channel are printed according to the user code transmitted by a pulse signal generator. A linear motor and push rod mechanism then push the designated number blocks from the channel and print them onto the wire insulation surface, achieving automatic, rapid, and accurate printing of the user code on the wire insulation.

[0034] 4. This invention provides a power line anti-crossing control system, which uses the cooperation between electricity meter A, electricity meter B, signal generator A, and signal generator B. Through the function of electricity meter A and electricity meter B, users can easily observe their own electricity consumption and determine whether there is crossing between their own lines and other users. This allows users to deal with it in a timely manner, thereby reducing the economic losses caused by crossing between lines and other users, and greatly reducing the impact of crossing between lines on users.

[0035] 5. This invention provides a power line anti-interference control system, which employs the cooperation of an insulating sleeve, a first C-shaped retaining ring, a reinforced insulating plate, a wear-resistant insulating pressure plate, a rubber insulating pressure strip, and a fixing locking ring. The reinforced insulating plate strengthens the internal structure of the first C-shaped retaining ring, preventing it from bending and deforming under the action of the fixing locking ring, thus improving the insulation effect of the insulating sleeve. The rubber insulating pressure strip and the wear-resistant insulating pressure plate increase the friction between the inner wall of the first C-shaped retaining ring and the outer wall of the line, preventing excessive external force from pulling the line out of the insulating sleeve and causing a short circuit.

[0036] 6. This invention provides a power line anti-interference control system, which employs the cooperation of an insulating sleeve, a fixing locking ring, a first locking plate, a second supporting spring, a second locking plate, a wear-resistant plate, and wear-resistant protrusions. The second supporting spring facilitates the first and second locking plates to press firmly against the outer wall of the insulating sleeve, preventing issues caused by a small diameter insulating sleeve where the inner walls of the first and second locking plates cannot contact the outer wall, thus affecting the installation of the signal generator. The wear-resistant plate and wear-resistant protrusions increase the friction between the inner wall of the second locking plate and the outer wall of the insulating sleeve, preventing the insulating sleeve from being pulled out of the inner cavity of the fixing locking ring, which would also affect the installation of the signal generator.

An elastic rope 633 is stretched along the outer end of each claw body 632 towards the base 631, causing the claw body 632 to open outwards under static force. A non-elastic rope 634 is fixedly connected to the inner end of each claw body 632 towards the sliding conductive core 62, allowing... When the sliding conductive core 62 moves backward, it pulls the claw body 632 to overcome the tension of the elastic rope 633 and grip the wire 5 inward. The outer circumference of the sliding conductive core 62 is provided with multiple grooves 621 at intervals along its length. An insulating trigger 611 is hinged to the first insulating outer cylinder 61 by a torsion spring. The insulating trigger 611 and the first insulating outer cylinder 61 have a limiting structure 612, which allows it to be activated only in one direction. One end of the insulating trigger 611 extends into the first insulating outer cylinder 61 and can engage with the groove 621, while the other end extends out of the first insulating outer cylinder 61 for operation. During the backward movement of the sliding conductive core 62, it is engaged by the insulating trigger 611 to prevent it from rebounding.

[0051] In this embodiment, the pulse signal generator also has a marking mechanism 7; the marking mechanism 7 is disposed at the front end of the quick-connect mechanism 6 and coaxially disposed with the quick-connect mechanism 6, the marking mechanism 7 includes a second insulating outer cylinder 71, an inner cylinder 72 fixedly sleeved inside the second insulating outer cylinder 71 at fixed intervals, and multiple sets of ring frames sleeved outside the inner cylinder 72; the multiple sets of ring frames are arranged parallel to each other, each set of ring frames includes ten frame positions, ten digital printing blocks 73 are respectively embedded in the frame positions and can slide radially along the frame positions and return to the initial position under the action of springs; a channel 721 is opened on the inner cylinder 72 along its length direction; a push rod mechanism 74 driven by a linear motor 75 is disposed on the inner wall of the second insulating outer cylinder 71 opposite to the channel 721; the push rod mechanism 74 can push the digital printing blocks 73 toward the axis direction and make the digital printing blocks 73 at the corresponding positions pass through the channel 721 and be printed on the outer surface of the insulation of the wire 5; the digital printing blocks 73 of each set of ring frames face The numbers 0 to 9 can be printed on one end of the axis; a gear shaft 77 driven by a servo motor 76 is also provided axially between the second insulating outer cylinder 71 and the ring frame; multiple gears 78 are sleeved on the gear shaft 77; the gears 78 mesh with the outer gear rings provided on the outer ring of the ring frame; each gear 78 includes an inner ring 781 and an outer ring 782; a bearing is sleeved between the inner ring 781 and the outer ring 782; multiple piezoelectric ceramic blocks 783 are provided between the inner ring 781 and the outer ring 782; an external circuit controls the piezoelectric ceramic blocks 783 to turn on and off, and when energized, the piezoelectric ceramic blocks 783 extend radially and simultaneously squeeze the inner ring 781 and the outer ring 782, causing the inner ring 781 and the outer ring 782 to rotate in linkage; the marking mechanism 7 also includes a controller, which receives the user code decoded and restored by the pulse electrical signal generator and controls the start and stop of the servo motor and the linear motor, and controls the energization of each piezoelectric ceramic block 783.

[0052] In this embodiment, the method for preventing cross-connection between households in the power line includes the following steps:

[0053] ① Install the pulse electrical signal receiver feedback unit in each meter household to be wired, and connect it via the quick-connect mechanism 6 or directly plug it into the socket in the household; input the user code through the input module during installation for each household;

[0054] ② Take the wire 5 from the external centralized wiring meter, remove a section of insulation from the head, pass it through the marking mechanism 7, and insert it into the quick-connect mechanism 6 of the pulse signal generator; the head of the wire 5, under pressure, moves the sliding conductive core 62 backward, and the non-elastic rope 634 pulls the claw body 632 to overcome the tension of the elastic rope 633 and grip the wire 5 inward; during the backward movement of the sliding conductive core 62, it is locked by the insulating trigger 611 to prevent it from springing back;

[0055] ③ The pulse transmitting module of the pulse signal generator transmits a pulse signal to the wire 5 through the sliding conductive core 62. The pulse signal is transmitted along the wire 5 to the pulse signal receiving feedback unit in the corresponding room. After receiving the pulse signal, the pulse signal receiving feedback unit sends a feedback signal that contains at least the signal marked by the user code. The decoding module of the pulse signal generator decodes the received signal and restores it to the user code, which is then displayed by the display module.

[0056] ④ The controller of the marking mechanism receives the user code information transmitted by the pulse electrical signal generator and converts it into control information for the servo motor, linear motor and external circuit. It controls the rotation of the servo motor and controls the power supply of each piezoelectric ceramic block 783 through the external circuit. This controls each ring frame to rotate by a certain angle through the gear 78, so that the combination of digital printing blocks 73 on each ring frame corresponding to the channel 721 is consistent with the user code. Then, it controls the linear motor to move. The linear motor drives the push rod mechanism 74 to push the entire row of digital printing blocks 73 to move towards the axis and pass through the channel 721 to print on the outer surface of the insulation of the wire 5.

[0060] In this embodiment, the signal generator body 3 is used to snap one end of the insulating sleeve 1, thereby facilitating the signal generator body 3 to detect the current in the circuit. The first C-shaped retaining ring 11 and the second C-shaped retaining ring 12 are used to prevent leakage at the connection between the signal generator body 3 and the circuit, thereby improving the safety of the circuit. The fixing plate 21 is fixed to the wall, and the distance between the second retaining plate 28 and the first retaining plate 24 is adjusted by the threaded locking cover 26 and the stud 27, thereby locking the connection between the first C-shaped retaining ring 11 and the second C-shaped retaining ring 12, thus achieving the purpose of installing the signal receiver.

[0061] In this embodiment, preferably, the first C-shaped retaining ring 11 includes a rigid insulating rubber plate 111, the outer wall of the rigid insulating rubber plate 111 overlaps with the inner wall of the second retaining plate 28, a soft insulating rubber plate 113 is fixedly connected to the inner wall of the rigid insulating rubber plate 111, a reinforcing insulating plate 112 is fixedly connected to the front side of the soft insulating rubber plate 113, an airbag plate 114 is fixedly connected to the inner wall of the soft insulating rubber plate 113, a wear-resistant insulating pressure plate 115 is fixedly connected to the inner wall of the airbag plate 114, and a rubber insulating pressure strip 116 is fixedly connected to the inner wall of the wear-resistant insulating pressure plate 115.

[0062] In this embodiment, the internal structure of the first C-shaped retaining ring 11 is reinforced by the reinforcing insulating plate 112, preventing the first C-shaped retaining ring 11 from bending and deforming under the action of the fixing locking ring 2, thereby improving the insulation effect of the insulating sleeve 1. The friction between the inner wall of the first C-shaped retaining ring 11 and the outer wall of the line is increased by the rubber insulating strip 116 and the wear-resistant insulating plate 115, preventing the line from being pulled out of the insulating sleeve 1 by excessive external force, thereby causing a short circuit in the line.

[0063] In this embodiment, preferably, a second support spring 25 is movably sleeved on the outer wall of the stud 27 and located between the first clamping plate 24 and the second clamping plate 28, and a first support spring 23 is movably disposed in the inner cavity of the support base 22. The second clamping plate 28 includes a clamping plate body 281, the back of the clamping plate body 281 is inserted into the outer wall of the stud 27, a wear-resistant plate 282 is fixedly connected to the top of the clamping plate body 281, and a wear-resistant protrusion 283 is fixedly connected to the top of the wear-resistant plate 282.

[0064] In this embodiment, the second support spring 25 facilitates the first clamping plate 24 and the second clamping plate 28 to press against the outer wall of the insulating sleeve 1, preventing the insulating sleeve 1 from being too small in diameter and thus failing to make contact with the outer wall of the insulating sleeve 1, which would affect the installation effect of the signal generator. The wear-resistant plate 282 and the wear-resistant protrusion 283 increase the friction between the inner wall of the second clamping plate 28 and the outer wall of the insulating sleeve 1, preventing the insulating sleeve 1 from being pulled out of the inner cavity of the fixing locking ring 2, which would also affect the installation effect of the signal generator.

[0065] In summary, as Figure 4-9 As shown, signal generator A detects the current entering the electricity meter A, and signal generator B detects the current output from the electricity meter B. The data detected by signal generators A and B are transmitted to a signal receiver, and then the received signal is transmitted to a signal processor. The detected data is analyzed and judged to determine if there is cross-connection. The functions of electricity meters A and B facilitate users' monitoring of their electricity consumption and help them determine if there is cross-connection, allowing for timely intervention and reducing economic losses caused by cross-connection. When installing the signal generator, first insert the first C-shaped retaining ring 1... The first C-shaped retaining ring 11 and the second C-shaped retaining ring 12 are snapped onto the outer wall of the line. Then, the signal generator body 3 is used to snap one end of the insulating sleeve 1, so that the signal generator body 3 can detect the current in the line. The first C-shaped retaining ring 11 and the second C-shaped retaining ring 12 are used to prevent leakage at the connection between the signal generator body 3 and the line, thereby improving the safety of the line. The fixing plate 21 is fixed to the wall. The distance between the second retaining plate 28 and the first retaining plate 24 is adjusted by the threaded locking cover 26 and the stud 27, thereby locking the connection between the first C-shaped retaining ring 11 and the second C-shaped retaining ring 12, thus achieving the purpose of installing the signal receiver.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
