[0060] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0061] The cover opening event of the existing electric energy meter is usually based on a button or switch configured in the content of the electric energy meter, and the cover opening event is detected by acquiring the level signal of the button or switch. However, the configured button or switch belongs to a mechanical structure, and with the change of time and environment, the button or switch will produce indirect misoperation, and the abnormal switching will cause false cover opening event, thereby reducing the detection efficiency of the cover opening event of the metering device. An embodiment of the present application provides a detection method for the cover opening event of the metering device, as shown in Figure 1 The method comprises the following steps.

[0062] 101, acquiring the cover opening event of the metering device and the receiving interval time of the carrier signal.

[0063] In an embodiment of the present application, the current execution subject can be a processor pre-configured and installed on the metering device, or a terminal device having remote data communication with the metering device, and the terminal device includes but is not limited to a server, a personal computer device, a cloud processor, etc. The metering device is a detection device suitable for different industrial production with a shell and limiting the shell based on the button cover opening, such as an electric energy meter in the electric power industry, a flow meter in pipeline transportation, etc. The embodiment of the present application is not limited specifically. Each metering device is configured with a button for opening and closing the shell of the metering device, and the button is electrically connected to the current execution subject to acquire the button level signal. Therefore, the cover opening event is determined based on the button level signal of the metering device, that is, for representing the cover opening state of the metering device shell. Specifically, the button is a button assembly with high and low level output function, such as a relay, etc. The embodiment of the present application is not limited specifically. In an embodiment of the present application, each metering device is also configured with a communication component for data communication to the current execution subject or a remote server, etc. At this time, the carrier signal is emitted by the communication component installed in the metering device. Since the communication component sends the carrier signal according to a specific time sequence, the transmission of communication data is realized. Therefore, after determining the model, hardware information or communication protocol of the communication component, the receiving interval time of the carrier signal of the current execution subject can be acquired.

[0064] It should be noted that, since the key is a component for opening and closing the metering device, the high and low level signals output as the trigger basis of the cover opening event, for example, the high level corresponds to the cover opening of the metering device, so that the cover opening event can be determined based on the key level signal, at this time, the correspondence between the high and low levels and the cover opening event can be pre-configured by the technical personnel, and the embodiment of the present application is not limited.

[0065] 102. If the detection time of the key level signal is greater than the receiving interval time, it is determined whether the communication component is in place relative to the metering device.

[0066] In the embodiment of the present application, the detection time of the key level signal is pre-configured and the length of time for triggering the determination of whether the cover is opened through the key level signal, if the detection time is greater than the receiving interval time of the communication component, it indicates that the metering device may be in an abnormal state of the communication component under the cover opening state, therefore, it is determined whether the communication component is in place relative to the metering device, in the embodiment of the present application, the receiving time interval can be pre-configured, such as 30 seconds, without specific limitation. Specifically, whether the communication component is in place relative to the metering device represents whether the communication component is separated from the metering device, in the embodiment of the present application, the communication component is installed inside the shell of the metering device under the normal cover closing state, at this time, the communication component is in place relative to the metering device, when the metering device is in the normal cover opening state, the communication component will be separated from the metering device, at this time, the communication component is not in place relative to the metering device.

[0067] It should be noted that, in the embodiment of the present application, the communication component is installed in the module compartment of the metering device, and when the metering device is opened, the communication component in the module compartment will be separated from the metering device body, so as to determine the in-place state between the communication component and the metering device.

[0068] 103. If the communication component is in place relative to the metering device, it is determined that the cover opening event is an abnormal cover opening event.

[0069] In the embodiment of the present application, when the communication component is in place relative to the metering device, it indicates that the communication component is also configured on the metering device, and no real cover opening of the metering device occurs, therefore, the cover opening event obtained based on the step 101 is a false judgment, and it is further indicated that the cover opening event of the metering device is an abnormal cover opening event, which greatly improves the accuracy of the cover opening event detection.

[0070] In another embodiment of the present application, in order to further limit and illustrate, the step of determining whether the communication component is in place relative to the metering device comprises: configuring a target pin of the communication component to be in an input state, and obtaining a pin level signal of the target pin in the input state, to determine whether the communication component is in place relative to the metering device based on the pin level signal.

[0071] In order to realize the judgment of whether the metering device has the cover opening abnormality based on the communication component, whether the communication component is in place relative to the metering device is judged by the pin level signal of the target pin of the configured communication component. Since the communication component can be a module unit including but not limited to a chip with a carrier signal, a single-chip microcomputer, etc., the target pin of the configured communication component is in an input state, at this time, the target pin can include but is not limited to a module reset pin RST, a meter sending and module receiving pin TXD, etc., and the embodiments of the present application are not limited specifically. At the same time, the pin level signal of the target pin in the input state is detected to judge whether the communication component is in place based on the pin level signal.

[0072] Correspondingly, in order to further limit and illustrate, before determining that the cover opening event is an abnormal cover opening event, the method further includes: if the pin level signal is a preset pin level signal, determining that the communication component is in a in-place state relative to the metering device.

[0073] Specifically, in the embodiments of the present application, a specified preset pin signal is configured for the target pin in advance as a basis for judging that the communication component is in a in-place state, that is, when the detected pin level signal of the target pin is a preset pin level signal, it is determined that the communication component is in a in-place state relative to the metering device. For example, when RST and TXD are both high level, it is determined that the communication component is in place. The preset pin signal can be that the target pin is all high level or all low level, and the embodiments of the present application are not limited specifically. In addition, in the embodiments of the present application, after the detection of the pin level signal of the target pin is completed, the target pin is reset to an output high level state to restore the communication function of the communication component.

[0074] In another embodiment of the present application, in order to further limit and illustrate, the step of judging whether the communication component is in place relative to the metering device includes: sending a response request to the communication component and detecting whether a response reply information is received to judge whether the communication component is in place relative to the metering device according to the response reply information.

[0075] In order to realize judging whether the metering device has the cover opening abnormal situation based on the communication component, whether the communication component is in place relative to the metering device is judged by sending a response request to the communication component by the current execution end, and judging whether the communication component is in place relative to the metering device based on whether the reply information is received. Since the communication component is configured on the metering device, if in place, the communication component can normally communicate data, if not in place, the communication component cannot normally communicate data, therefore, the response request is sent to the communication component, and whether the reply information is received is detected to judge whether the communication component is in place. For example, a read chip ID information request is sent to the communication component, whether the chip ID information reply information of the communication component is received is detected to judge whether the communication component is in place.

[0076] Correspondingly, in order to further limit and illustrate, before determining that the cover opening event is an abnormal cover opening event, the method further includes: if the reply information is received, determining that the communication component is in a in-place state relative to the metering device.

[0077] Specifically, in the embodiment of the application, the request content of the response request can be pre-configured, which is not limited, after the current execution end sends the request response, if the reply information of the request response is received, it indicates that the communication component can normally communicate data, therefore, it is determined that the communication component is in a in-place state relative to the metering device.

[0078] In another embodiment of the application, in order to further limit and illustrate, as shown in the method further includes: Figure 2 before the step of acquiring the cover opening event of the metering device and the receiving interval time of the carrier signal, the method further includes:

[0079] 201, after the metering device completes the power-on operation, whether the message information sent by the communication component is received within a first preset time interval is detected;

[0080] 202, if the message information is received, it is determined that the communication component completes the installation in the metering device.

[0081] In the embodiment of the present application, in order to realize the abnormal detection of the opening cover event of the metering device based on the communication component, it is necessary to determine in advance whether the communication component is installed in the recording device to ensure the transmission and reception of the carrier signal of the communication component. First, the metering device is powered on, that is, the metering device can be powered on based on the power line, or the metering device can be powered on through the device battery, which is not limited in the embodiment of the present application. When the power-on operation is completed, the metering device is in a normal running state, and the current execution end determines whether the communication component is in normal communication by detecting whether the message information sent by the communication component can be received. The first preset time interval is a time length for judging whether the message information is received, which can be 10 seconds, 1 minute, etc., and is not limited in the embodiment of the present application. At the same time, if the message information sent by the communication component is detected within the first preset time interval, it is indicated that the communication component is normally running in the metering device, and the message information is preferably a legal message, so it can be determined that the communication component is normally installed in the metering device, and the opening cover event abnormal detection is combined with the communication component in the case of normal installation. For example, if the legal message of the module is received after the power-on of the electric meter, it is determined that the communication module is installed in the electric meter, and if no message is received, it is determined that there is no communication module, as shown in Figure 3

[0082] In another embodiment of the present application, in order to further limit and illustrate, as shown in Figure 4 the method further comprises the following steps before the step of obtaining the opening cover event of the metering device and the receiving interval time of the carrier signal:

[0083] 301, obtaining the key level signal of different metering devices in a second preset time interval;

[0084] 302, generating the opening cover event of the metering device according to the comparison result of the key level signal and the preset opening cover level signal, and storing the opening cover event and the detection time of the key level signal.

[0085] ​In the embodiment of the present application, in order to improve the accuracy of the cover opening judgment based on the key level signal, the cover opening event of the metering device needs to be detected in advance, so as to judge based on the cover opening event combined with the communication component. Specifically, the key level signals of different metering devices in a second preset time interval are obtained. At this time, since the metering devices can be installed at metering targets in different positions, the key level signals of different metering devices can be collected, and when it is necessary to detect the cover opening event, the key level signals of different metering devices in a second preset time interval are obtained for unified judgment. The second preset time interval can be 1 day, 1 week, etc., which is not limited in the embodiment of the present application. At the same time, a cover opening level signal is preset, such as a high level, so that after the key level signal is compared with the preset cover opening level signal, the cover opening event of the metering device is generated, such as when the key level signal is detected as a high level, the cover opening event of the metering device is generated, indicating that the metering device is in an open state at this time. In addition, in order to facilitate the abnormal judgment of the cover opening event of the metering device, the cover opening event and the corresponding detection time are stored, so as to compare the receiving interval time with the detection time to determine whether the cover opening event is abnormal, thereby improving the accuracy of the cover opening event detection.

[0086] In another embodiment of the present application, in order to further limit and illustrate, the step further comprises: if the detection time of the key level signal is less than or equal to the receiving interval time, it is determined that the communication component is in the in-place state relative to the metering device, and the cover opening event is an abnormal cover opening event.

[0087] Since the interval time of the transmission carrier signal of the communication component installed in the metering device is the basis for judging the communication component, at this time, if the detection time of the key level signal is less than or equal to the receiving interval time, it indicates that a cover opening event occurs within a carrier signal receiving interval in the normal communication process of the communication component, and the cover opening is abnormal. Therefore, it is determined that the communication component is in the in-place state of the metering device at this time, and the cover opening event is an abnormal cover opening event, which meets the requirement of detecting the cover opening abnormality in the receiving interval time period.

[0088] In another embodiment of the present application, in order to further limit and illustrate, the step further comprises: reporting the abnormal cover opening event to perform offline inspection on the metering device; and when the abnormal cover opening event detection is completed, if no packet information of the metering device is received within a third preset time interval, a reset operation is performed on the target pin of the communication component to re-judge whether the communication component is in the in-place state relative to the metering device.

[0089] In the embodiment of the present application, in order to ensure the processing efficiency of the abnormal cover opening event, avoid the metering error caused by the abnormal cover opening event, report the abnormal cover opening event, so that the operator can perform offline inspection on the metering device with the abnormal cover opening event. In addition, after completing the abnormal cover opening event detection, in order to enable the metering device to normally operate and perform normal metering operation, whether the message information of the communication component can be received is detected within a third preset time interval. If not, it means that the communication component is abnormal. At this time, the target pin of the communication component is reset to re-determine whether the communication component is in the in-place state relative to the metering device. The third preset time interval can be 24 hours, 2 days, etc., which is not limited in the embodiment of the present application. For example, if no legal communication message is received for more than 24 hours, the RST pin can be reset, and the communication component can be reset to read the communication reading number of the electric meter again to re-determine whether the electric meter is installed with the communication component, which is not limited in the embodiment of the present application.

[0090] In addition, in the embodiment of the present application, the generated cover opening event can also be directly reported. That is, if the reporting instruction of the cover opening event is opened, the generated cover opening event is directly reported, which is not limited in the embodiment of the present application.

[0091] In one specific implementation scenario in the embodiment of the present application, as shown in Figure 5 After the cover opening level is detected, the cover opening event is generated and recorded. It is judged whether the electric meter is provided with a carrier module as a communication component. If yes, it is judged whether the detection time is greater than the receiving interval time of the carrier signal. If yes, it is judged whether the carrier module is in place based on the target pin RST, TXD or request reading chip ID information. If yes, it is determined that the cover opening event is an abnormal cover opening event.

[0092] The embodiment of the present application provides a detection method for a cover opening event of a metering device. Compared with the prior art, the embodiment of the present application acquires a cover opening event of a metering device and a receiving interval time of a carrier signal. The cover opening event is determined based on a key level signal of the metering device. The carrier signal is emitted by a communication component installed in the metering device. If the detection time of the key level signal is greater than the receiving interval time, it is judged whether the communication component is in place relative to the metering device. If the communication component is in the in-place state relative to the metering device, it is determined that the cover opening event is an abnormal cover opening event. The embodiment of the present application avoids the key false alarm caused by the single determination of the cover opening event based on the key level judgment mode, greatly reduces the frequency of abnormal cover opening reporting, and improves the detection accuracy of the cover opening event of the metering device.
