Description

Technical Field

[0001] The present invention relates to the technical field of electric variable measuring instruments, and in particular to an electric energy meter and a control method thereof. Background Art

[0002] An electric energy meter is an instrument used to measure electrical energy, also known as an watt-hour meter, fire meter or kilowatt-hour meter. Due to its small size, high accuracy, good reliability and easy installation, it is becoming more and more commonly used in industrial production and life.

[0003] Common smart electricity meters all have a power carrier communication module, which transmits electricity charges and electricity usage information to the main electricity meter in the form of a power carrier. The main electricity meter then sends the statistics to the power company via a 4G signal.

[0004] The electric energy meter includes a bottom shell, a cover shell, a circuit board and a communication module. The cover shell is installed on the bottom shell, and the circuit board is installed between the bottom shell and the cover shell. A groove is formed on the surface of the cover shell, and the communication module is placed in the groove. A meter cover is hinged on the cover shell, and the meter cover cover is used to cover the groove. The end of the meter cover cover that is not hinged to the cover shell is fixed with bolts to achieve the installation of the communication module. Since the communication module is a wireless data transmission terminal in the electric energy meter, criminals only need to unscrew the bolts to steal the electric energy meter accessories, and the electric energy meter has poor anti-theft performance. Summary of the invention

[0005] The invention provides an electric energy meter and a control method, which can improve the anti-theft performance of the electric energy meter.

[0008] In one possible implementation, a baffle is fixedly connected inside the support tube; an unlocking plate is arranged inside the support tube above the baffle, and the unlocking plate can be slidably inserted into the sleeve and slide axially along the support tube to push the spring piece to be accommodated in the accommodating hole; an elastic member is arranged between the baffle and the unlocking plate, which enables the unlocking plate to slide back and forth axially along the support tube; and an unlocking member is connected to the baffle, which can compress the elastic member.

[0009] In a possible implementation, the elastic member includes: a guide tube vertically fixed to the baffle, an adjustment tube slidably inserted in the guide tube, and an elastic body located in the guide tube and pressed against the lower end surface of the adjustment tube.

[0010] In a possible implementation, the elastic body is a spring.

[0011] In one possible implementation, the unlocking member includes: a cable having one end connected to the unlocking plate and the other end passing through the baffle along the central axis of the baffle, an unlocking rod located below the baffle and passing through the support tube and slidable along the radial direction of the support tube, and an unlocking plate connected to the unlocking rod to pull the unlocking rod to slide; one end of the unlocking rod facing away from the unlocking plate is fixedly connected to the cable so that the unlocking plate abuts against the support tube.

[0012] In a possible implementation, the unlocking rod is located below the accommodating hole along the axial direction of the support tube, and the top end of the unlocking piece is located at one side of the accommodating hole.

[0013] In a possible implementation, a sliding groove is formed in the unlocking plate along the radial direction of the unlocking plate and penetrates the circumferential side wall of the unlocking plate, and a reinforcement rod is slidably inserted in the sliding groove; a reinforcement hole is opened in the side wall of the sleeve, and an elastic body is arranged in the sliding groove, and the elastic body pushes the reinforcement rod so that one end of the reinforcement rod is inserted into the reinforcement hole; a guide surface is formed on the part of the reinforcement rod located outside the sliding groove, so that the sleeve abuts against the guide surface and pushes the reinforcement rod to retract into the sliding groove; one end of the cable is inserted into the sliding groove and fixedly connected to the reinforcement rod, so that the cable is pulled to retract the reinforcement rod into the sliding groove.

[0014] In a second aspect, an embodiment of the present invention provides a control method for an electric energy meter, which is applied to an electric energy meter as in any one of the first aspects, wherein a limit hole is provided in the middle position of one side of the sleeve; a linkage switch is provided on the side of the connecting ear close to the limit hole; when the communication module is installed in the groove, the linkage switch is arranged relative to the limit hole; the control method comprises: detecting a status signal of the linkage switch; determining whether the sleeve is in situ based on the status signal of the linkage switch; if the sleeve is not in situ, obtaining the value of the alarm flag of the electric energy meter; if the value of the alarm flag of the electric energy meter indicates an alarm cancellation state, generating a status record of the linkage switch and storing it; if the value of the alarm flag of the electric energy meter indicates an alarm state, generating an alarm instruction, the alarm instruction being used to instruct the electric energy meter to perform an audible and visual alarm and send an alarm message.

[0015] In a possible implementation, the control method further includes: receiving a maintenance instruction input by a user, the maintenance instruction being used to instruct the electric energy meter to switch to a maintenance state; if the state of the electric energy meter is the maintenance state, setting the value of the alarm flag of the electric energy meter to an alarm clearing state.

[0016] The present invention provides an electric energy meter and a control method. The present invention connects a connection ear with a through hole on a communication module, and sets a support tube in a groove, with the through hole facing the support tube, and then inserts a sleeve into the support tube from the through hole. With the spring piece clamped in the lock hole, the connection between the communication module and the cover is completed. The spring piece is protected in the support tube, and the spring piece cannot be moved out of the sleeve from the outside, so that the connection ear is always locked between the sealing plate and the support tube, so as to improve the anti-theft performance of the electric energy meter. And when in use, only the sealing plate is needed to realize the locking of the communication module, so as to achieve the effect of convenient use.

[0017] In addition, the present invention provides a baffle at the free end of the spring piece. When criminals try to pry the sealing plate, the baffle reduces the gap between the spring piece and the support tube during the upward movement of the sleeve, thereby reducing the upward movement height of the sealing plate, making it difficult for criminals to insert their tools between the sealing plate and the connecting ear, thereby improving the anti-theft performance of the electric energy meter.

[0018] The present invention can also enable the elastic member to be compressed and move along the axial direction of the support tube by setting an unlocking plate and an unlocking member. At this time, the unlocking plate abuts against the spring sheet and gradually pushes the sleeve to deflect into the support tube, and pulls the sleeve upward under the guidance of the baffle to completely separate the spring sheet from the sleeve, so as to remove the sleeve. When the sealing plate is pried by lawbreakers to separate the sealing plate from the sleeve, or when the staff actively pries the sealing plate to separate it from the sleeve because the communication module needs to be replaced, it is convenient to remove the sleeve from the support tube to replace a new sleeve with a sealing plate, so as to fix the communication module there, so as to achieve the effect of facilitating the reuse of the electric energy meter.

[0019] The present invention can also be provided with an unlocking member including a cable, an unlocking rod and an unlocking piece. When the communication module is removed, the blocking unlocking piece without the connection ear is exposed to the outside. At this time, the unlocking rod is pulled by the unlocking piece, and the cable is finally pulled to compress the elastic member, so that the unlocking plate slides along the axial direction of the support tube, and the sleeve is taken out of the support tube. And by setting the top of the unlocking piece to be located on one side of the receiving hole, such a setting makes it easy for the staff to use an external tool to insert it into the receiving hole and pry the unlocking piece outward, so as to achieve the effect of being easy for the staff to use.

[0020] The present invention can also provide a slide groove and a reinforcement hole on the basis of providing an unlocking plate and an unlocking member, so that after the sleeve is inserted into the support tube, the reinforcement rod is inserted into the reinforcement hole under the action of the elastic body, so that the unlocking plate and the sleeve are connected as a whole, and because the elastic body connects the baffle plate and the unlocking plate, the stability of the sleeve and the support tube after being locked is improved. When the sleeve is first inserted into the support tube, the guide surface pushes the reinforcement rod to shrink into the slide groove and compresses the elastic body so that the reinforcement rod is inserted into the reinforcement hole; when the reinforcement rod is already in the reinforcement hole, when the unlocking plate is pulled to separate the spring piece from the sleeve, the reinforcement rod can be pulled synchronously to separate it from the reinforcement hole, which has the effect of improving the connection strength between the sleeve and the support tube while facilitating the separation of the two.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following will be described through specific embodiments in conjunction with the accompanying drawings of the present invention.

[0045] The present embodiment relates to an electric energy meter to improve the anti-theft performance of the electric energy meter. In terms of overall structure, the electric energy meter includes a cover 1, a groove 101 for placing a communication module 2 is formed on the cover 1, and a cover cover 102 for shielding the groove 101 is hinged on the cover 1, and the unhinged end of the cover cover 102 is connected to the cover 1 by bolts. The communication module 2 is circumferentially connected to a connecting ear 201 extending outward, and a through hole 2011 is provided on the connecting ear 201; a support tube 3 fixedly connected to the cover shell 1 is provided at the bottom of the groove in the groove 101, and the pipe mouth of the support tube 3 is opposite to the through hole 2011; an accommodating hole 301 is provided along the axial direction of the support tube 3 and on the side wall of the support tube 3, and a spring 4 inclined to the support tube 3 is fixedly connected to the hole wall of the accommodating hole 301 near the connecting ear 201; a sealing plate 5 is provided on the side of the connecting ear 201 away from the support tube 3, and the sealing plate 5 is fixedly connected to a sleeve 6 that can be inserted into the support tube 3 through the through hole 2011, and a locking hole 601 is provided on the side wall of the sleeve 6 for the spring 4 to be inserted.

[0046] By connecting the connection ear 201 with the through hole 2011 on the communication module 2, and setting the support tube 3 in the groove 101, the through hole 2011 is directly opposite to the support tube 3, and then the sleeve 6 is inserted into the support tube 3 from the through hole 2011, and the spring piece 4 is clamped in the lock hole 601, the connection between the communication module 2 and the cover 1 is completed, the spring piece 4 is protected in the support tube 3, and the spring piece 4 cannot be moved out of the sleeve 6 from the outside, so that the connection ear 201 is always locked between the sealing plate 5 and the support tube 3, so as to improve the anti-theft performance of the electric energy meter. And when in use, only the sealing plate 5 is needed to realize the locking of the communication module 2, achieving the effect of convenient use.

[0047] Based on the above overall introduction, Figures 1 to 5As shown, it can be understood that in this embodiment, the connecting ear 201 is fixed on the circumferential side wall of the communication module 2, and the connecting ear 201 is located on the side close to the notch of the groove 101, and the connecting ear 201 extends outward until it abuts against the groove side wall of the groove 101. Specifically, in this embodiment, the connecting ear 201 is annularly fixedly connected to the communication module 2. Specifically, the spring sheet 4 is in an inclined state and extends into the support tube 3 when it is naturally free of force; when the spring sheet 4 is squeezed by the sleeve 6 and the spring sheet 4 is contracted into the accommodating hole 301, when the spring sheet 4 is facing the lock hole 601, the spring sheet 4 can automatically rebound and reset and be plugged into the lock hole 601.

[0048] On the basis that the spring piece 4 is inserted into the lock hole 601, the free end of the spring piece 4 is fixedly connected with a blocking piece 401, the inclination direction of the blocking piece 401 is opposite to the inclination direction of the spring piece 4, and the bottom end of the blocking piece 401 is spaced from the bottom wall of the lock hole 601; the blocking piece 401 can be synchronously moved to the outside of the support tube 3 when the spring piece 4 is located in the accommodating hole 301.

[0049] By setting a baffle 401 at the free end of the spring sheet 4, when criminals try to pry the sealing plate 5, the setting of the baffle 401 reduces the gap between the spring sheet 4 and the support tube 3 during the upward movement of the sleeve 6, thereby reducing the upward movement height of the sealing plate 5, so that it is difficult for criminals to insert their tools between the sealing plate 5 and the connecting ear 201, thereby improving the anti-theft performance of the electric energy meter. It can be understood that the free end of the spring sheet 4 refers to the end of the spring sheet 4 that is not connected to the support tube 3, and the baffle 401 is in an inclined state opposite to the spring sheet 4.

[0050] On the basis of setting the baffle 401, in order to facilitate the overall replacement of the sealing plate 5 and the sleeve 6 when the sealing plate 5 is damaged, a baffle 7 is fixedly connected in the support tube 3; an unlocking plate 8 is arranged in the support tube 3 above the baffle 7, and the unlocking plate 8 can be slidably inserted into the sleeve 6 to abut the inner wall of the sleeve 6 and slide axially along the support tube 3 to push the spring piece 4 to be accommodated in the accommodating hole 301; an elastic member 9 is arranged between the baffle 7 and the unlocking plate 8, which can enable the unlocking plate 8 to slide back and forth axially along the support tube 3; the baffle 7 is connected to an unlocking member 10 that can compress the elastic member 9.

[0051] By setting the unlocking plate 8 and the unlocking member 10, the elastic member 9 can be compressed and moved along the axial direction of the support tube 3. At this time, the unlocking plate 8 abuts against the spring sheet 4, and gradually pushes the sleeve 6 to deflect into the support tube 3, and pulls the sleeve 6 upward under the guidance of the baffle 401 to completely separate the spring sheet 4 from the sleeve 6, so as to remove the sleeve 6. When the sealing plate 5 is pried by lawbreakers to separate the sealing plate 5 from the sleeve 6, or when the staff actively pries the sealing plate 5 to separate it from the sleeve 6 because the communication module 2 needs to be replaced, it is convenient to remove the sleeve 6 from the support tube 3 to replace the new sleeve 6 with the sealing plate 5, so as to fix the communication module 2 here, so as to achieve the effect of facilitating the reuse of the electric energy meter.

[0052] As an implementable method, the elastic member 9 includes a guide tube 901 vertically fixed to the baffle 7, an adjustment tube 902 slidably inserted in the guide tube 901, and an elastic body 903 located in the guide tube 901 and pressed against the lower end surface of the adjustment tube 902. The elastic body 903 is a spring. It can be understood that the adjustment tube 902 can be inserted in the guide tube 901 to achieve axial sliding along the guide tube 901, and one end of the adjustment tube 902 is always located in the guide tube 901. How to make one end of the adjustment tube 902 always located in the guide tube 901 is a conventional technical means and will not be elaborated here. In this embodiment, the specific guide tube 901 and the adjustment tube 902 have a central axis in the length direction that is collinear with the central axis in the length direction of the support tube 3.

[0053] As an implementable manner, the unlocking member 10 includes a cable 1001 with one end connected to the unlocking plate 8 and the other end passing through the baffle 7 along the central axis of the baffle 7, an unlocking rod 1002 located below the baffle 7 and slidable along the radial direction of the support tube 3 passing through the support tube 3, and an unlocking piece 1003 connected to the unlocking rod 1002 to pull the unlocking rod 1002 to slide; one end of the unlocking rod 1002 away from the unlocking piece 1003 is fixedly connected to the cable 1001, so that the unlocking piece 1003 abuts against the support tube 3. The unlocking rod 1002 is located below the accommodating hole 301 along the axial direction of the support tube 3, and the top end of the unlocking piece 1003 is located at one side of the accommodating hole 301.

[0054] By setting the unlocking member 10 to include the cable 1001, the unlocking rod 1002 and the unlocking piece 1003, when the communication module 2 is removed, the unlocking piece 1003 that blocks the connection ear 201 is exposed to the outside, and at this time, the unlocking rod 1002 is pulled by the unlocking piece 1003, and finally the cable 1001 is pulled to compress the elastic member 9, so that the unlocking plate 8 slides along the axial direction of the support tube 3, and the sleeve 6 is taken out of the support tube 3. And by setting the top of the unlocking piece 1003 to be located at one side of the accommodating hole 301, such a setting is convenient for the staff to use an external tool to insert into the accommodating hole 301 and pry the unlocking piece 1003 outward, so as to achieve the effect of being convenient for the staff to use.

[0055] It can be understood that, as described above, when the elastic member 9 is configured to include a guide tube 901, an adjusting tube 902 and the elastomer 903 is configured as a spring, one end of the cable 1001 is connected to the unlocking plate 8, and the other end passes through the adjusting tube 902, the elastomer 903 and the guide tube 901 in sequence and finally passes through the baffle 7 and is connected to the unlocking rod 1002, and the cable 1001 can slide relative to the adjusting tube 902, the elastomer 903, the guide tube 901 and the baffle 7.

[0056] On the basis of setting the unlocking plate 8, the unlocking member 10 and the elastic member 9, in order to further improve the connection stability between the sleeve 6 and the support tube 3, a slide groove 801 is formed in the unlocking plate 8 along the radial direction of the unlocking plate 8 and penetrates the circumferential side wall of the unlocking plate 8, and a reinforcing rod 11 is slidably inserted in the slide groove 801; a reinforcing hole 602 is opened on the side wall of the sleeve 6, and an elastic body 1101 is arranged in the slide groove 801, and the elastic body 1101 pushes the reinforcing rod 11 so that one end of the reinforcing rod 11 is inserted into the reinforcing hole 602; a guide surface 11a is formed on the part of the reinforcing rod 11 located outside the slide groove 801, so that the sleeve 6 pushes the reinforcing rod 11 to retract into the slide groove 801 after abutting against the guide surface 11a; one end of the cable 1001 is inserted into the slide groove 801 and is fixedly connected to the reinforcing rod 11, so that the cable 1001 is pulled to retract the reinforcing rod 11 into the slide groove 801.

[0057] By providing the slide groove 801 and the reinforcement hole 602, after the sleeve 6 is inserted into the support tube 3, the reinforcement rod 11 is inserted into the reinforcement hole 602 under the action of the elastic body 1101, so that the unlocking plate 8 and the sleeve 6 are connected as a whole, and the elastic body 903 connects the baffle plate 7 and the unlocking plate 8, so as to improve the stability of the sleeve 6 and the support tube 3 after being locked. When the sleeve 6 is first inserted into the support tube 3, the guide surface 11a pushes the reinforcement rod 11 to shrink into the slide groove 801 and compresses the elastic body 1101, so that the reinforcement rod 11 is inserted into the reinforcement hole 602; when the reinforcement rod 11 is already in the reinforcement hole 602, when the unlocking piece 1003 is pulled to make the spring piece 4 separate from the sleeve 6, the reinforcement rod 11 can be pulled synchronously to separate it from the reinforcement hole 602, which has the effect of improving the connection strength between the sleeve 6 and the support tube 3 and facilitating the separation of the two.

[0058] It can be understood that the cable 1001 can slide through the unlocking plate 8 from the bottom center of the unlocking plate 8 and then be fixedly connected with one end of the reinforcing rod 11 abutting against the elastic body 1101. In order to facilitate the fixed connection between the cable 1001 and the reinforcing rod 11 abutting against the elastic body 1101, the elastic body 1101 preferably uses a spring in this embodiment so that the elastic body 1101 can be sleeved outside the cable 1001.

[0059] It can be understood that the guide surface 11a is in an inclined state, and when the elastic body 1101 is in a natural state, the guide surface 11a is formed on the part of the reinforcing rod 11 located in the slide groove 801. Specifically, the end surface of the reinforcing rod 11 located outside the slide groove 801 gradually tilts toward the side close to the unlocking plate 8 from the end close to the elastic body 1101 to the end away from the elastic body 903, so that when the end surface of the support tube 3 abuts on the guide surface 11a, the reinforcing rod 11 is pushed to retract into the slide groove 801 under the action of the guide surface 11a. Preferably, the end surface of the support tube 3 in contact with the guide surface 11a is an inclined surface, and the end surface can completely abut on the guide surface 11a.

[0060] The electric energy meter described in the embodiment of the present application, when fixing the communication module 2, the communication module 2 is placed in the groove 101, and the through hole 2011 is opposite to the support tube 3, and then the sleeve 6 is inserted into the sleeve 6 through the through hole 2011, the sleeve 6 abuts the guide surface 11a and pushes the reinforcing rod 11 to shrink into the slide groove 801 under the action of the guide surface 11a, the sleeve 6 continues to slide axially along the support tube 3, and when the sleeve 6 abuts the spring piece 4, it pushes the spring piece 4 to be accommodated in the accommodating hole 301 until the spring piece 4 is clamped in the locking hole 601, and the synchronous reinforcing rod 11 is inserted in the reinforcing hole 602, and at this time, the sealing plate 5 is pressed against the connecting ear 201 to complete the anti-theft installation of the communication module 2.

[0061] When the sealing plate 5 is forcefully destroyed by criminals or the staff actively damages the sealing plate 5 when replacing the communication module 2 and replaces the sealing plate 5 and the sleeve 6, the unlocking piece 1003 is pried toward the side away from the support tube 3. At this time, the cable 1001 pulls the reinforcing rod 11 to make the reinforcing rod 11 disengage from the reinforcing hole 602 and compress the elastomer 903. The cable 1001 is continued to be pulled, and the elastic member 9 is compressed. At this time, the unlocking plate 8 slides along the axial direction of the support tube 3 and pushes the spring piece 4, so that the spring piece 4 is accommodated in the accommodating hole 301, thereby realizing the removal of the sleeve 6.

[0062] By connecting the connection ear 201 with the through hole 2011 on the communication module 2, and setting the support tube 3 in the groove 101, the through hole 2011 is directly opposite to the support tube 3, and then the sleeve 6 is inserted into the support tube 3 from the through hole 2011, and the spring piece 4 is clamped in the lock hole 601, the connection between the communication module 2 and the cover 1 is completed, the spring piece 4 is protected in the support tube 3, and the spring piece 4 cannot be moved out of the sleeve 6 from the outside, so that the connection ear 201 is always locked between the sealing plate 5 and the support tube 3, so as to improve the anti-theft performance of the electric energy meter. And when in use, only the sealing plate 5 is needed to realize the locking of the communication module 2, achieving the effect of convenient use.

[0063] like Figure 6 As shown, the embodiment of the present invention also provides a control method for an electric energy meter. Figures 1 to 5 In the electric energy meter shown, a limiting hole 12 is provided in the middle of one side of the sleeve 6; a linkage switch is provided on one side of the connecting ear 201 close to the limiting hole 12; when the communication module 2 is installed in the groove 101, the linkage switch is arranged opposite to the limiting hole 12. The control method includes steps S101-S105.

[0064] S101, detecting the status signal of the linkage switch.

[0065] S102: Determine whether the casing is in the original position based on the status signal of the linkage switch.

[0066] S103: If the bushing is not in the original position, obtain the value of the alarm flag of the electric energy meter.

[0067] S104: If the value of the alarm flag of the electric energy meter indicates the alarm clearing state, a state record of the linkage switch is generated and stored.

[0068] S105: If the value of the alarm flag of the electric energy meter indicates an alarm state, an alarm instruction is generated.
