And immediately carry out related processing.

Referring to FIG. 7 and FIG. 8, a second preferred embodiment of the meter device 100 of the present invention, the difference between the second preferred embodiment and the first preferred embodiment described as follows. In this embodiment, the second housing 21 of the control module 2 has a first housing portion 211 and a second housing portion 213. The first housing portion 211 has an inner surface 212 that faces the control circuit 24. The control circuit 24 also has a third end 243 and a fourth end 244. The control circuit 24 can detect a short circuit or an open circuit between the third end 243 and the fourth end 244. The control module 2 further includes a second tamper detecting component 26.

Referring to FIG. 7 , FIG. 8 and FIG. 9 , when the first shell portion 211 is connected to the second shell portion 213 , the free end portion 262 of the second tamper detecting element 26 contacts the third end 243 and the fourth end of the control circuit 24 . 244, shorting the third end 243 and the fourth end 244. The control circuit 24 controls the communication unit 22 to wirelessly measure the measurement result of the measuring unit 12 when detecting a short circuit between the first end 241 and the second end 242 and short-circuiting between the third end 243 and the fourth end 244. Send it out to the base station 200.

Referring to FIG. 7, FIG. 8 and FIG. 10, when the first shell portion 211 is separated from the second shell portion 213, the free end portion 262 of the second tamper detecting element 26 and the third end 243 and the fourth end of the control circuit 24 are separated. The 244 separates, thereby opening an open path between the third end 243 and the fourth end 244. The control circuit 24 controls the communication unit 22 to send a second warning signal to the base station 200 when detecting that the third terminal 243 and the fourth terminal 244 are open. Therefore, if a person intends to disassemble the second housing 21 of the control module 2 (ie, the first shell portion 211 and the second shell portion) 213 separate) and the control circuit 24 or the second transmission unit 23 feeds a false measurement signal, and the power company can immediately receive the second warning signal through the 3G communication network and immediately perform related processing. The electric meter device 100 of the present embodiment can emit a first warning signal when the control module 2 is separated from the measurement module 1, and can also be issued when the first shell portion 211 of the control module 2 is separated from the second shell portion 213.

Sound, which produces an immediate deterrent effect.

Referring to Figures 11 and 12, there is shown a third preferred embodiment of the meter device of the present invention. The difference between this embodiment and the first preferred embodiment and the second preferred embodiment is mainly that the control method of the control circuit 24 is different.

The control module 2 of the embodiment further includes a storage unit 29 disposed on the second housing 21 and electrically connected to the control circuit 24. The storage unit 29 stores a predetermined open circuit sequence and a predetermined time limit. The predetermined open circuit sequence defines an open sequence between the first end 241 and the second end 242 and between the third end 243 and the fourth end 244. The control circuit 24 is operable in a transmission state S01, an alarm state S02, a countdown state S03, and a maintenance state S04. When the first end 241 and the second end 242 are short-circuited and the third end 243 and the fourth end 244 In the short circuit, the control circuit 24 operates in the transmission state S01. In the transmission state S01, the control circuit 24 controls the communication unit 22 to wirelessly transmit the measurement result of the measurement unit 12 to the base station 200.

In the transmission state S01, if the first end 241 and the second end 242 or between the third end 243 and the fourth end 244 are open, and the predetermined open circuit sequence is not met, the control circuit 24 enters the alarm state S02. For example, if the predetermined open circuit sequence defines an open sequence between the third end 243 and the fourth end 244 prior to the open sequence between the first end 241 and the second end 242, if the first end is in the transmission state S01 241 and the second end 242 are switched from open to open, and the control circuit 24 will enter the alarm state S02 from the transmission state S01. In the alarm state S02, the control circuit 24 controls the communication unit 22 to send an alert signal to the base station 200, and controls the lighting unit 26 to emit light in a blinking manner and control the speaker 27 to emit a warning tone.

In the transmission state S01, if the first end 241 and the second end 242 or between the third end 243 and the fourth end 244 are open, and the predetermined open circuit sequence is met, the control circuit 24 enters the reciprocal state S03. For example, if the predetermined open circuit sequence defines an open sequence between the third end 243 and the fourth end 244 prior to the open sequence between the first end 241 and the second end 242, if the third end is in the transmission state S01 Between the 243 and the fourth terminal 244 is switched from open to open, and the control circuit 24 will enter the reciprocal state S03 from the transmission state S01.

In the reciprocal state S03, if there is no open circuit between the first end 241 and the second end 242 and between the third end 243 and the fourth end 244 within the predetermined time limit, the control unit 24 enters an alarm state S02. If you mentioned above For example, in the transmission state S01, since the third end 243 and the fourth end 244 are switched from open to open, the control circuit 24 enters the reciprocal state S03, and in the reciprocal state S03, the predetermined time limit (for example, 30 seconds). The first end 241 and the second end 242 are not switched from open to open, and the control circuit 24 enters the alarm state S02.

In the reciprocal state S03, if there is an open circuit between the first end 241 and the second end 242 and between the third end 243 and the fourth end 244 within the predetermined time limit, the control unit 24 enters the maintenance state S04. In the maintenance state S04, the control circuit 24 does not control the communication unit 22 to send the measurement result, but can perform the detection or the parts replacement by the power supply meter maintenance tester. In the maintenance state S04, if the first end 241 and the second end 242 are short-circuited and the third end 243 is short-circuited with the fourth end 244, the control circuit 24 enters the transmission state S01.

According to the foregoing control method, if the intentional person attempts to detach the control module 2 from the measurement module 1 and the dummy second measurement unit 23 feeds the dummy measurement signal, if the predetermined open circuit sequence defines the third end The open sequence between the 243 and the fourth end 244 precedes the open sequence between the first end 241 and the second end 242, and the control circuit 24 enters an alarm state S02, and the power company can immediately perform the relevant processing. If the intentional person attempts to detach the control module 2 from the measurement module 1 and the second transmission unit 23 feeds the dummy measurement signal, even if the predetermined open circuit sequence defines between the first end 241 and the second end 242 The open circuit sequence precedes the open sequence between the third end 243 and the fourth end 244, so that when the control module 2 is detached from the measurement module 1, the control module 24 does not enter the alarm state S02 and enters the countdown state S03. However, if the person concerned believes that the second transmission unit 23 has been exposed, the first shell portion 211 and the second shell are not continued. When the portion 213 is separated, the control circuit 24 will still enter the alarm state S02.

Similarly, if a person intends to disassemble the second housing 21 of the control module 2 and the exposed control circuit 24 or the second transmission unit 23 feeds a false measurement signal, if the predetermined open sequence defines the first The open sequence between the end 241 and the second end 242 precedes the open sequence between the third end 243 and the fourth end 244, and the control circuit 24 enters the alarm state S02, and the power company can immediately perform the relevant processing. In addition, if a person intends to disassemble the second casing 21 of the control module 2 and the exposed control circuit 24 or the second transmission unit 23 feeds a false measurement signal, even if the predetermined open sequence defines the third end 243 The open sequence between the fourth end 244 and the second end 244 precedes the open sequence between the first end 241 and the second end 242 such that the control module 24 does not enter the alarm state S02 and enters the countdown when the second housing 21 is disassembled. In the state S03, if the person in charge thinks that the control circuit 24 and the second transmission unit 23 in the second casing 21 are exposed and does not continue to detach the control module 2 from the measurement module 1, the control circuit 24 will still enter. Alarm status S02.

Therefore, if the person concerned does not disassemble according to the predetermined open circuit sequence and the predetermined time limit, the meter device 100 immediately issues a warning signal, thereby effectively preventing the intentional person from disassembling the meter device 100. In addition, when the electric meter maintenance tester wants to perform the maintenance test on the electric meter device 100, the control circuit 24 can be brought into the reciprocal state S03 and then enter the maintenance by the transmission state S01 in sequence according to the predetermined open circuit sequence and the predetermined time limit. State S04 for maintenance testing. After the maintenance test is completed, as long as the meter device 100 is assembled and restored, the control circuit 24 enters the transmission state S01 from the maintenance state S04, so that the meter device 100 continues to operate normally.

It should be noted that the predetermined open sequence and the predetermined time limit of the embodiment are received by the communication unit 22 and stored in the storage unit 29. Thereby, the power company can periodically transmit different predetermined open circuit sequences and predetermined time limits to the meter device 100 through the base station 200, that is, the predetermined open circuit sequence and the predetermined time limit stored by the power meter device 100 are periodically updated, thereby effectively improving the defense. The security of the dismantling mechanism.
