[0033] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0035] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0036] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] Figure 1 FIG. 1 is a schematic diagram of the structure of a safety control device according to an embodiment of the present disclosure. Figure 1 As shown, the safety control device includes a first detection module 11 , a second detection module 12 and an indication module 13 .

[0040] The first detection module 11 detects whether there is a communication failure in the energy monitoring switch device.

[0041] In some embodiments, the first detection module 11 sends a detection signal to the energy monitoring switch device at a predetermined frequency so that the energy monitoring switch device sends a detection response signal corresponding to the detection signal. If the first detection module 11 fails to receive the detection response signal sent by the energy monitoring switch device, it is determined that there is a communication failure in the energy monitoring switch device.

[0042] In some embodiments, the first detection module 11 and the energy monitoring switch device communicate wirelessly via the LORA protocol.

[0043] The second detection module 12 detects the current working state of the load device when there is a communication failure in the energy monitoring switch device.

[0044] In some embodiments, the second detection module 12 detects the current voltage value and the current current value of the output terminal of the energy monitoring switch device. When the current voltage value of the output terminal of the energy monitoring switch device is within a predetermined voltage range and the current current value is less than a predetermined current threshold, the second detection module 12 determines that the load device is currently in a non-working state.

[0045] For example, the second detection module 12 determines that the load device is currently in the shutdown state when the current voltage value at the output end of the energy monitoring switch device is within the predetermined voltage range and the current current value is zero. It should be noted that when the load device is currently in the shutdown state, the output end of the energy monitoring switch device has a normal voltage output but no current output.

[0046] For another example, the second detection module 12 determines that the load device is currently in the standby state when the current voltage value at the output end of the energy monitoring switch device is within the predetermined voltage range and the current current value is within the predetermined current range. It should be noted here that when the load device is currently in the standby state, the output end of the energy monitoring switch device has a normal voltage output, but the current at this time is much smaller than the current when the load device is working normally. For example, in this case, the current output of the output end of the energy monitoring switch device is 10mA to 100mA.

[0047] In some embodiments, when the load device is currently in a working state, the second detection module 12 repeatedly performs the operation of detecting the current working state of the load device until the load device is currently in a non-working state.

[0048] For example, the second detection module 12 determines that the load device is currently in the working state when the current voltage value of the output end of the energy monitoring switch device is within the predetermined voltage range and the current current value is not less than the predetermined current threshold.

[0049] When the load device is currently in a non-working state, the indication module 13 indicates the user to turn off the energy monitoring switch device so as to perform maintenance on the energy monitoring switch device.

[0050] In the safety control device provided in the above embodiment of the present disclosure, by detecting that there is a communication failure in the energy monitoring switch device, the current working state of the load device is further detected. When the load device is currently in a non-working state, the user is instructed to turn off the energy monitoring switch device so that the user can repair the energy monitoring switch device in time.

[0051] It should be noted here that when the load device is in the shutdown state or standby state, the user can directly turn off the energy monitoring switch device and remove the energy monitoring switch device from the circuit for maintenance. When the load device is in the working state, directly turning off the energy monitoring switch device may affect the performance of the load device. To this end, the working state of the load device can be continuously monitored, and the energy monitoring switch device can be turned off after the load device enters the shutdown state or standby state from the working state.

[0052] Figure 2 It is a schematic structural diagram of a safety control device according to another embodiment of the present disclosure. Figure 2 and Figure 1 The difference is that in Figure 2 In the illustrated embodiment, the safety control device further includes a switch control module 14 .

[0053] The switch control module 14 sends a switch control signal to the energy monitoring switch device so as to control the switch state of the energy monitoring switch device. For example, the switch control module 14 sends an on control signal to the energy monitoring switch device so that the energy monitoring switch device is in an on state, thereby providing the electric energy provided by the power supply device to the load device. For another example, the switch control module 14 sends an off control signal to the energy monitoring switch device so that the energy monitoring switch device is in an off state, thereby cutting off the electrical connection between the power supply device and the load device.

[0054] In some embodiments, the switch control module 14 and the energy monitoring switch device communicate wirelessly via the LORA protocol.

[0058] In step 302, when there is a communication failure in the energy monitoring switch device, the current working state of the load device is detected.

[0059] In some embodiments, by detecting the current voltage value and the current current value of the output end of the energy monitoring switch device, when the current voltage value at the output end of the energy monitoring switch device is within a predetermined voltage range and the current current value is less than a predetermined current threshold, it is determined that the load device is currently in a non-working state.

[0060] For example, when the current voltage value at the output end of the energy monitoring switch device is within a predetermined voltage range and the current current value is zero, it is determined that the load device is currently in a shutdown state. For another example, when the current voltage value at the output end of the energy monitoring switch device is within a predetermined voltage range and the current current value is within a predetermined current range, it is determined that the load device is currently in a standby state. The above-mentioned predetermined current range can be 10mA to 100mA.

[0061] In some embodiments, when the load device is currently in a working state, the step of detecting the current working state of the load device is repeatedly performed until the load device is currently in a non-working state.

[0062] For example, when the current voltage value at the output end of the energy monitoring switch device is within a predetermined voltage range and the current current value is not less than a predetermined current threshold, it is determined that the load device is currently in a working state.

[0063] In step 303, when the load device is currently in a non-working state, the user is instructed to turn off the energy monitoring switch device so as to perform maintenance on the energy monitoring switch device.

[0064] In some embodiments, a switch control signal is sent to the energy monitoring switch device so as to control the switch state of the energy monitoring switch device.
