It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] Figure 1 The present invention provides a structural diagram of an electric energy meter with switchable electricity tariff. Figure 1 As shown, the electric energy meter 1 comprises:

[0040] A control module 10 and a switching trigger circuit 20;

[0041] The control module 10 includes at least one switching port, which is electrically connected to the switching trigger circuit 20 and is used to receive a switching instruction sent by the switching trigger circuit 20;

[0042] The control module 10 switches the electricity rate to the electricity rate corresponding to the switching instruction according to the received switching instruction.

[0043] The control module 10 may be a control chip inside the electric energy meter, such as a single chip microcomputer, MCU, etc. The control module 10 may be used to calculate the electricity cost according to the consumption of electric energy, and the control module 10 may include a storage module inside for storing rate data, time data, user data, etc.

[0044] In this embodiment, the control module 10 can select the corresponding electricity rate according to the received switching instruction, and different switching instructions correspond to different electricity rates. And the control module 10 can switch to the rate corresponding to the switching instruction after receiving the switching instruction at a certain moment, so as to be used for subsequent electricity billing. That is, the electricity rate can be switched according to the switching instructions received at different times, so as to meet the billing needs of different rates in different time periods.

[0045] The switching trigger circuit 20 can respond to an output signal according to a controlled signal, and at least one switching port of the control module 10 is electrically connected to the output port corresponding to the switching trigger circuit 20. When the switching trigger circuit 20 has only one output port and the control module 10 corresponds to one switching port, the output signal of one output port of the switching trigger circuit 20 is the switching instruction. When the switching trigger circuit 20 includes multiple output ports and the control module 10 corresponds to multiple switching ports, the control module 10 receives the output signals of multiple output ports of the switching trigger circuit 20, and the control module 10 identifies the switching instruction composed of multiple output signals to switch the electricity rate. It should be noted that the controlled signal can be a signal set manually, which triggers the controlled signal after the set time point, thereby controlling the switching trigger circuit 20 to output the corresponding output signal.

[0046] The technical solution of the embodiment of the present invention is to receive the switching instruction sent by the switching trigger circuit at the detection switching port of the control module, and switch the electricity rate to the electricity rate corresponding to the switching instruction according to the switching instruction. That is, the present invention only needs to control the switching instruction sent by the switching trigger circuit at the necessary time point to realize the switching of the rate, thereby completing the setting of different electricity charges in different time periods, and there is no need to install infrared communication and RS485 communication equipment on the electric energy meter to realize the rate and time period setting inside the electric energy meter through remote communication, thereby reducing the cost of the electric energy meter.

[0047] In such Figure 2 In the embodiment of the electric energy meter with switchable electricity tariff shown, the switching trigger circuit includes at least one switching circuit, and the number of the switching circuits corresponds to the number of the switching ports.

[0048] The switching trigger circuit 20 includes at least one switching circuit 21 . Each switching circuit 21 can respond to an output signal after receiving a controlled signal and output the output signal to the switching port of the control module 10 .

[0049] like Figure 2 As shown, the switching trigger circuit 20 of the electric energy meter includes two switching circuits 21, each of which is connected to two switching ports of the control module 10 respectively, and is used to output an output signal to the corresponding switching port respectively.

[0050] In such Figure 2 In the embodiment of an electric energy meter with switchable electricity rates shown in the figure, the first input end of the switching circuit 21 is electrically connected to the live wire 30, and the second input end of the switching circuit 21 is connected or disconnected to the neutral wire 31 after being controlled; the output end of the switching circuit 21 is electrically connected to the switching port, and the electrical level received by the switching port changes as the second input end of the switching circuit 21 is connected or disconnected to the neutral wire.

[0051] like Figure 2 As shown, Figure 2 The first input ends of the two switching circuits 21 of the switching trigger circuit 20 are both electrically connected to the live wire 30; the second input ends of the two switching circuits 21 are electrically connected or disconnected to the neutral wire 31 after being controlled, that is, the switching circuit 21 and the neutral wire 31 are connected by a dotted line; when the second input end of the switching circuit 21 is electrically connected or disconnected to the neutral wire 31 after being controlled, the output signal of the switching circuit 21 will also change accordingly, for example, when the second input end of the switching circuit 21 is disconnected from the neutral wire 31, the output signal of the switching circuit 21 is a high level, and when the second input end of the switching circuit 21 is connected to the neutral wire 31, the output signal of the switching circuit 21 is a low level; of course, it can also be that when the second input end of the switching circuit 21 is disconnected from the neutral wire 31, the output signal of the switching circuit 21 is a low level, and when the second input end of the switching circuit 21 is connected to the neutral wire 31, the output signal of the switching circuit 21 is a high level. In this embodiment, the controlled signal can be a signal set in advance by humans, and after the set time point, the neutral wire 31 is controlled to be connected to the first input end of the switching circuit, thereby controlling the switching circuit 21 to output a corresponding output signal.

[0052] In such Figure 3 In an embodiment of a switching trigger circuit provided, a first output terminal of the switching circuit 21 is electrically connected to the switching port, and a second output terminal of the switching circuit 21 is grounded.

[0053] The switching circuit includes an optical coupler relay;

[0054] The first input end of the photocoupler relay is connected to the first input end of the switching circuit 21; the second input end of the photocoupler relay is connected to the live wire; the first input end of the photocoupler relay is connected to the positive electrode of the light-emitting diode in the photocoupler relay, and the second input end of the photocoupler relay is connected to the negative electrode of the light-emitting diode in the photocoupler relay;

[0055] The first end of the photosensitive switch of the optocoupler relay is electrically connected to the switching port, and the second end of the photosensitive switch is grounded; the photosensitive switch is closed when it receives the light energy of the light-emitting diode, and is opened when it does not receive the light energy of the light-emitting diode; the switching port is in a high level state when the photosensitive switch does not receive the light energy of the light-emitting diode.

[0056] Specifically, the first input end of the switching circuit is connected to the first end of the first resistor, the second end of the first resistor is connected to the cathode of the first diode and the anode of the light-emitting diode respectively; the anode of the first diode and the cathode of the light-emitting diode are both connected to the first end of the second resistor, and the second end of the second resistor is connected to the live wire;

[0057] The first end of the photosensitive switch is electrically connected to the switching port, the first end of the third resistor and the first end of the first capacitor respectively, and the second end of the photosensitive switch is grounded; the second end of the third resistor is connected to the power supply, and the second end of the first capacitor is grounded.

[0058] like Figure 3 As shown, the optocoupler relay can be of model LTV-816S-TP-D3; the first resistor can be Figure 3 The resistor R66 and R65 are connected in series; the first diode can be Figure 3 D1 and D11 in; Figure 3 The switching ports in are FLQH-1 and FLQH-2 respectively; the third resistor can be Figure 3 R21 and R211 in; the first capacitor can be Figure 3 The capacitors are formed by connecting C25 and C27 in parallel, and the capacitors are formed by connecting C251 and C271 in parallel.

[0059] Figure 3 FLQH-1 and FLQH-2 are level detection signals for detecting whether the first input terminals (13 ports and 15 ports) of the two switching circuits 21 of the switching circuit 21 are connected to the neutral line (20 ports and 21 ports). In the initial state, when the first input terminal of the switching circuit 21 is not connected to the neutral line, it is at a high level, and the second input terminals of the two switching circuits 21 are connected to the live wire of the electric energy meter. When the first input terminal (13 port) and the neutral line (20 port) of a switching circuit 21 are short-circuited (when connected to the neutral line of the electric energy meter), the normal high-level signal of FLQH-1 will change to a low-level signal. Similarly, when the first input terminal (15 port) and the neutral line (21 port) of the second switching circuit 21 are short-circuited (when connected to the neutral line of the electric energy meter), the normal high-level signal of FLQH-2 will also change to a low-level signal.

[0060] Figure 4 is a circuit diagram of a control module 10 provided in an embodiment of the present invention, Figure 4 FLQH-1 and FLQH-2 corresponding to ports 61 and 62 of the control module 10 are the switching ports of the control module 10, which are set correspondingly to the output terminals of the two switching circuits 21 of the switching trigger circuit 20. When the high and low levels of ports 61 and 62 are detected to change, different rates and time periods are executed according to the corresponding program logic. Four sets of rates and time periods can be respectively corresponded according to the four different states of the two switching ports.

[0061] For example 1. FLQH-1 and FLQH-2 are both in high level state 00

[0062] For example 2. FLQH-1 and FLQH-2 are both in low level state 11

[0063] For example 3. FLQH-1 is low level, FLQH-2 is high level state 10

[0064] For example 4. FLQH-1 is high level, FLQH-2 is low level state 01

[0065] It can correspond to 4 different rates and time periods. The time period corresponding to each rate can be defined according to customer needs. For example, when the 00 state is triggered at 0:00 p.m., the corresponding rate is 0.3 yuan KW / h; when the 01 state is triggered at 8:00 a.m., the corresponding rate is 0.5 yuan KW / h; when the 10 state is triggered at 12:00 p.m., the corresponding rate is 0.4 yuan KW / h; when the 11 state is triggered at 18:00 p.m., the corresponding rate is 0.6 yuan KW / h. The above is only an exemplary description.

[0066] In one embodiment, the number of the switch ports is N;

[0067] The switch port includes two states: high level and low level;

[0068] The control module 10 switches to the corresponding electricity rate according to the change of the state of the N switching ports; the electricity rate is at most 2 N , respectively corresponding to the number of combinations of N switching port states.

[0069] In this embodiment, the switching port includes two states: high level and low level, and the number of switching ports is N. For example, when the number of switching ports is 2, the switching signal is 2 bits, and the generated switching signals include 00, 01, 10, and 11, which can correspond to four rates respectively. For example, the four switching signals correspond to 0.3 yuan, 0.4 yuan, 0.5 yuan, and 0.6 yuan respectively; when the number of switching ports is 3, the switching signal is 3 bits, and the generated switching signals include 000, 001, 010, 011, 100, 101, 110, and 111, which can correspond to eight rates respectively. Similarly, when the number of switching ports is N, the switching signal is 2 N The control module 10 can switch to the corresponding electricity rate according to the change of the status of the N switching ports.

[0070] In a specific embodiment, the physical diagram of the electric energy meter with switchable electricity rate of the present invention is as follows Figure 5 As shown, Figure 5 The control module 10 and the switching trigger circuit 20 are both arranged inside the electric energy meter 1, and the first input terminals and the neutral line ports of the two switching circuits can be arranged at the external interface of the electric energy meter, for example Figure 5 Terminal 13 is the first input terminal of the switching circuit 21, and terminal 20 is the neutral line port. When terminal 13 is short-circuited and connected to terminal 20, FLQH-1 is at a low level and FLQH-2 is at a high level. At this time, the control module 10 detects that the levels of these two IO ports have changed, and immediately switches the rate. Terminal 15 is the first input terminal of another switching circuit 21, and terminal 21 is the neutral line port. When terminal 15 is short-circuited and connected to terminal 21, FLQH-1 is at a high level and FLQH-2 is at a low level. At this time, the control module 10 detects that the levels of these two IO ports have changed, and immediately switches the rate.

[0073] S602: When the states of the plurality of switching ports change, obtain the first electricity rate corresponding to the current states of the plurality of switching ports, and switch the second electricity rate at the previous moment to the first electricity rate for calculating subsequent electricity charges.

[0074] The technical solution of the embodiment of the present invention is to receive the switching instruction sent by the switching trigger circuit at the detection switching port of the control module, and switch the electricity rate to the electricity rate corresponding to the switching instruction according to the switching instruction. That is, the present invention only needs to control the switching instruction sent by the switching trigger circuit at the necessary time point to realize the switching of the rate, thereby completing the setting of different electricity charges in different time periods, and there is no need to install infrared communication and RS485 communication equipment on the electric energy meter to realize the rate and time period setting inside the electric energy meter through remote communication, thereby reducing the cost of the electric energy meter.
