Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The uncapping event of the existing electric energy meter is generally based on configuring a key or a switch in the content of the electric energy meter, and the uncapping event is detected by acquiring a level signal of the key or the switch. However, the configured keys or switches belong to a mechanical structure, indirect misoperation can be generated on the keys or switches along with the change of time and environment, and the generated abnormal switching can cause wrong uncapping events, so that the efficiency of detecting the uncapping events of the metering equipment is reduced. An embodiment of the present invention provides a method for detecting an uncapping event of a metering device, and as shown in fig. 1, the method includes:
101. and acquiring the uncapping event of the metering equipment and the receiving interval time of the carrier signal.
In an embodiment of the present invention, the current execution main body may be a processor configured in advance to be installed on the metering device, or a terminal device having remote data communication with the metering device, where the terminal device includes, but is not limited to, a server, a personal computer device, a cloud processor, and the like, and the metering device is a detection device which is suitable for different industrial production and has a housing and limits the housing to be opened based on a button, such as an electric energy meter in the power industry, a flow meter in pipeline transportation, and the like, and the embodiment of the present invention is not particularly limited. Each metering device is provided with a key independently used for opening and closing the shell of the metering device, the key is electrically connected with the current execution main body to acquire a key level signal, and therefore, the uncapping event is determined based on the key level signal of the metering device, namely, the uncapping event is used for representing the uncapping state of the shell of the metering device. Specifically, the key is a key assembly having a function of outputting high and low levels, such as a relay, and the embodiment of the present invention is not limited in particular. In the embodiment of the present invention, each metering device is further configured with a communication component for performing data communication to a current execution main body or a remote server, and the like, at this time, the carrier signal is sent by the communication component installed in the metering device, and the communication component sends the carrier signal according to a specific time sequence, so as to implement transmission of communication data, and therefore, after the model, hardware information, or communication protocol of the communication component is determined, the receiving interval time of the carrier signal of the current execution main body can be obtained.
It should be noted that, because the key is a component for opening and closing the metering device, the output high and low level signals are used as triggering bases of the decapping event, for example, the high level corresponds to decapping of the metering device, so that the decapping event can be determined based on the key level signals, at this time, the correspondence between the high and low levels and the decapping event can be configured in advance based on a technician, and the embodiment of the present invention is not limited specifically.
102. And if the detection time of the key level signal is longer than the receiving interval time, judging whether the communication assembly is in place relative to the metering equipment.
In the embodiment of the present invention, the detection time of the key level signal is a time length that is configured in advance and is used for triggering the determination of whether to open the lid through the key level signal, and if the detection time is longer than the reception interval time of the communication component, it is described that there may be a case where the communication component is abnormal in the state where the metering device is opened at that time, and therefore, it is determined whether the communication component is in place with respect to the metering device. Specifically, whether the communication component is in place relative to the metering device is characterized as whether the communication component is separated from the metering device, in the embodiment of the present invention, when the metering device is in a normal cover closing state, the communication component is installed inside the metering device housing, and at this time, the communication component is in place relative to the metering device, when the metering device is in a normal cover opening state, the communication configuration is separated from the metering device, and at this time, the communication component is not in place relative to the metering device.
It should be noted that, in the embodiment of the present invention, 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 is separated from the metering device body, so as to determine the in-place state between the communication component and the metering device.
103. And if the communication assembly is in an in-place state relative to the metering equipment, determining that the uncapping event is an abnormal uncapping event.
In the embodiment of the invention, when the communication component is in the on-position state relative to the metering device, the communication component is still configured on the metering device, and the real uncapping condition of the metering device does not occur, so that the uncapping event obtained based on the step 101 is misjudged, and the uncapping event of the metering device is further described as an abnormal uncapping event, so that the accuracy of uncapping event detection is greatly improved.
In another embodiment of the present invention, for further definition and illustration, the step of determining whether the communication assembly is in place relative to the metering device comprises: and configuring a target pin of the communication assembly as an input state, and acquiring a pin level signal of the target pin in the input state to judge whether the communication assembly is in place relative to the metering equipment or not based on the pin level signal.
In order to judge whether the metering device is in an abnormal uncapping state or not based on the communication assembly, whether the communication assembly is in place relative to the metering device or not is judged specifically through a pin level signal of a target pin of the configured communication assembly. The communication component may include, but is not limited to, a chip that transmits a carrier signal, a single chip, and other module units, and thus the target pin of the communication component is configured to be in an input state, and at this time, the target pin may include, but is not limited to, a module reset pin RST, an electric meter transmission and module reception pin TXD, and the like. Meanwhile, a pin level signal of the target pin in an input state is detected, and whether the communication assembly is in place is judged based on the pin level signal.
Correspondingly, for further definition and explanation, before the decap event is determined to be an abnormal decap event, the method further includes: and if the pin level signal is a preset pin level signal, determining that the communication assembly is in an in-place state relative to the metering equipment.
Specifically, in the embodiment of the present invention, a predetermined pin signal is configured in advance for the target pin, and the predetermined pin signal is used as a basis for determining that the communication component is in the on-position state, that is, when the detected pin level signal of the target pin is the predetermined pin level signal, it is determined that the communication component is in the on-position state relative to the metering device. For example, when RST and TXD are both high, it is determined that the communication component is in place. The preset pin signal may be that the target pins are all at a high level or all at a low level, and the embodiment of the present invention is not limited in particular. In addition, in the embodiment of the invention, after the pin level signal detection of the target pin is finished, the target pin is reset to output high level, so as to recover the communication function of the communication assembly.
In another embodiment of the present invention, for further definition and illustration, the step of determining whether the communication assembly is in place relative to the metering device comprises: and sending a response request to the communication assembly, detecting whether response reply information is received or not, and judging whether the communication assembly is in place relative to the metering equipment or not according to the response reply information.
In order to realize the judgment of whether the metering device is abnormally uncovered based on the communication component, the communication component sends a response request to the communication component through the current execution end as to whether the communication component is in place relative to the metering device, and the judgment of whether the communication component is in place relative to the metering device is carried out based on whether reply information is received. The communication component is configured on the metering equipment, if the communication component is in place, the communication component can carry out normal data communication, and if the communication component is not in place, the normal data communication cannot be carried out, so that a response request is sent to the communication component, and whether response reply information is received or not is detected to judge whether the communication component is in place or not. For example, a read chip ID information request is sent to the communication component, and it is determined whether the communication component is in place by detecting whether a response reply information of the chip ID information of the communication component is received.
Correspondingly, for further definition and explanation, before the decap event is determined to be an abnormal decap event, the method further includes: and if the response reply message is received, determining that the communication assembly is in an in-place state relative to the metering equipment.
Specifically, in the embodiment of the present invention, request content of the response request may be configured in advance, and without specific limitation, after the current execution end sends the request response, if response reply information of the request response is received, it is indicated that the communication component may perform data communication normally, so that it is determined that the communication component is in an in-place state with respect to the metering device.
In another embodiment of the present invention, for further definition and explanation, as shown in fig. 2, before the step of acquiring the decapping event of the metering device and the receiving interval time of the carrier signal, the method further includes:
201. after the metering equipment completes the power-on operation, detecting whether message information sent by the communication assembly is received within a first preset time interval;
202. and if the message information is received, determining that the communication assembly completes installation in the metering equipment.
In the embodiment of the present invention, in order to implement abnormal detection of a decapping event of a metering device based on a communication component, it is necessary to determine in advance whether the communication component is installed in a recording device, so as to ensure transmission and reception of a carrier signal of the communication component. Firstly, the metering device is powered on, that is, the metering device may be powered on based on an electric wire, or the metering device may be powered on through a device battery, which is not specifically limited in the embodiment of the present invention. After the power-on operation is completed, the metering equipment is in a normal operation state, and the current execution end determines whether the communication assembly is in normal communication or not by detecting whether message information sent by the communication assembly can be received or not. The first preset time interval is a preset time length for judging whether the message information is received, and may be 10 seconds, 1 minute, and the like, and the embodiment of the present invention is not particularly limited. Meanwhile, if the message information sent by the communication component is detected within the first preset time interval, it is indicated that the communication component normally operates in the metering device, and the message information is preferably a legal message, so that it can be determined that the communication component completes normal installation in the metering device, and the communication component is combined with the communication component to perform abnormal detection of the uncapping event under the condition of normal installation. For example, after the electric meter is powered on, if a legal message of the module is received, it is determined that the communication module is installed in the electric meter, and if the message is not received, it is determined that there is no communication module, as shown in fig. 3.
In another embodiment of the present invention, for further definition and explanation, as shown in fig. 4, before the step of acquiring the decapping event of the metering device and the receiving interval time of the carrier signal, the method further includes:
301. acquiring key level signals of different metering devices within a second preset time interval;
302. and generating a cover opening event of the metering equipment according to the comparison result of the key level signal and a preset cover opening level signal, and storing the cover opening event and the detection time of the key level signal.
In the embodiment of the invention, in order to improve the accuracy of uncapping judgment based on the key level signal, the uncapping event of the metering equipment needs to be detected in advance, so that the judgment is carried out based on the uncapping event and the communication assembly. Specifically, key level signals of different metering devices in the second preset time interval are obtained, at this moment, because the metering devices can be installed at metering targets at different positions, the key level signals of different metering devices can be collected, and when an uncapping event needs to be detected, the key level signals of different metering devices in the second preset time interval are obtained, so that unified judgment is carried out. The second preset time interval may be 1 day, 1 week, etc., and the embodiment of the present invention is not limited in particular. Meanwhile, a uncapping level signal, such as a high level, is preset so that after the key level signal is compared with the preset uncapping level signal, an uncapping event of the metering device is generated, and if the key level signal is detected to be the high level, the uncapping event of the metering device is generated, and the uncapping state of the metering device is indicated. In addition, in order to conveniently judge the abnormity of the uncapping event of the metering equipment, the uncapping event and the corresponding detection time are stored, so that whether the uncapping event is abnormal or not is determined based on the comparison between the receiving interval time and the detection time, and the accuracy of uncapping event detection is improved.
In another embodiment of the present invention, for further definition and explanation, the steps further comprise: and if the detection time of the key level signal is less than or equal to the receiving interval time, determining that the communication assembly is in an in-place state relative to the metering equipment, and the uncapping event is an abnormal uncapping event.
The interval time of sending the carrier signal of the communication assembly installed in the metering equipment is a basis for judging the communication assembly, at the moment, if the detection time of detecting the key level signal is less than or equal to the receiving interval time, the uncovering event occurs in a carrier signal receiving interval in the normal communication process of the communication assembly, the uncovering is abnormal, and therefore the communication assembly is determined to be in the on-site state of the metering equipment at the moment, the uncovering event is an abnormal uncovering event, and the requirement of detecting the uncovering abnormality in the receiving interval time period content is met.
In another embodiment of the present invention, for further definition and explanation, the steps further comprise: reporting the abnormal uncapping event to carry out offline inspection on the metering equipment; and after the abnormal uncapping event detection is finished and the message information of the metering equipment is not received within a third preset time interval, resetting the target pin of the communication assembly to judge that the communication assembly is in the in-place state relative to the metering equipment again.
In the embodiment of the invention, in order to ensure the processing efficiency of the abnormal uncapping event and avoid the metering error caused by the abnormal uncapping event, the abnormal uncapping event is reported so that an operator can perform offline inspection on the metering equipment with the abnormal uncapping event. In addition, after the abnormal uncapping event detection is completed, in order to enable the metering equipment to normally operate and execute normal metering operation, whether message information of the communication assembly can be received is detected at a third preset time interval or more, if the message information is not received, the communication assembly is abnormal, and at the moment, the target pin of the communication assembly is reset to judge that the communication assembly is in the in-place state relative to the metering equipment again. The third preset time interval may be 24 hours, 2 days, and the like, and the embodiment of the present invention is not particularly limited. For example, if no legal communication message is received for more than 24 hours, the RST pin is reset, and the communication reading number of the electric meter is read again after the communication component is reset, so as to determine whether the electric meter is provided with the communication component again.
In addition, in the embodiment of the present invention, the generated decapping event may also be directly reported, that is, after the report instruction of the decapping event is started, the generated decapping event is detected and is directly reported, and the embodiment of the present invention is not particularly limited.
In a specific implementation scenario in the embodiment of the present invention, as shown in fig. 5, after detecting a decapping level, a decapping event is generated and recorded, whether a carrier module serving as a communication component is provided in an electric meter is determined, if so, it is determined that a carrier detection time is greater than a reception interval time of a carrier signal, whether the carrier module is in place is determined based on a target pin RST, a TXD or a request to read chip ID information, and if so, it is determined that the decapping event is an abnormal decapping event.
Compared with the prior art, the method for detecting the uncapping event of the metering equipment comprises the steps that the uncapping event of the metering equipment and the receiving interval time of a carrier signal are obtained, the uncapping event is determined based on a key level signal of the metering equipment, and the carrier signal is sent out by a communication assembly installed in the metering equipment; if the detection time of the key level signal is longer than the receiving interval time, judging whether the communication assembly is in place relative to the metering equipment or not; if the communication assembly is in an in-place state relative to the metering equipment, the uncovering event is determined to be an abnormal uncovering event, the condition of key false alarm caused by the fact that the uncovering event is determined based on a key level judging mode is avoided, the frequency of abnormal uncovering reporting is greatly reduced, and therefore the detection accuracy of the uncovering event of the metering equipment is improved.
Further, as an implementation of the method shown in fig. 1, an embodiment of the present invention provides an apparatus for detecting an uncapping event of a metering device, where as shown in fig. 6, the apparatus includes:
an obtaining module 41, configured to obtain a decapping event of a metering device and a receiving interval time of a carrier signal, where the decapping event is determined based on a key level signal of the metering device, and the carrier signal is sent by a communication component installed in the metering device;
