It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a method for detecting an operating state of equipment according to an embodiment of the present invention, which is applicable to a case where an operating state of equipment whose operating state is changed by a mechanical operation is detected, and the method can be executed by an apparatus for detecting an operating state of equipment.
S110, when the equipment vibrates, respectively acquiring vibration information of the equipment based on vibration sensors which are preset at least two target positions on the equipment.
Wherein the device comprises a device whose operating state can be changed by mechanical operation. For example, the device is a circuit breaker that can change the power-on state by switching a button. The vibration information refers to information acquired by a vibration sensor when the device vibrates, such as vibration amplitude, vibration time and the like. The method comprises the steps that vibration sensors are arranged at different target positions on equipment in advance, vibration display is carried out on the equipment, vibration information is obtained through the vibration sensors at the different target positions, and the obtained vibration information of the equipment is different due to the fact that the target positions arranged on the vibration sensors are different. The vibration sensor acquires the vibration information of the equipment and prepares for subsequent judgment of the abnormal running state of the equipment.
For example, at least two target positions for detecting vibration are determined based on a target detection event of the device, and vibration sensors are disposed at the at least two target positions.
The target detection event comprises an event when the operation state of the equipment is changed through mechanical operation, such as a closing event of a circuit breaker. The target position refers to a position where the vibration sensor is placed, such as the periphery of a switch button of the circuit breaker. At least two target positions for detecting vibration are determined according to the position of the target detection event of the device, and vibration sensors are arranged at the at least two target positions. For example, the target position is different from the target detection event, so that the vibration information acquired by the vibration sensor is more representative.
And S120, determining the running state of the equipment based on the acquired vibration information at the at least two target positions.
The running state of the equipment comprises a normal running state and an abnormal running state. After the vibration information at the at least two target positions is obtained, the operation state of the equipment is judged by analyzing the vibration information so as to determine the operation state of the equipment. When the equipment vibrates, different vibration information acquired by the vibration sensors at different target positions is used for determining whether the current running state of the equipment is abnormal or not according to the vibration information, such as whether the closing operation of the circuit breaker is delayed or not or whether the circuit breaker is in a closing fault or other problems. The equipment running state detection method can enable the equipment running state abnormity to be judged more accurately.
According to the technical scheme of the embodiment of the invention, the vibration sensors which are arranged at least two target positions on the equipment in advance are used for respectively acquiring the vibration information of the equipment when the equipment vibrates, and then determining the running state of the equipment based on the acquired vibration information at the at least two target positions. According to the technical scheme of the embodiment of the invention, the vibration sensors arranged at least two target positions on the equipment are adopted to respectively obtain the vibration information, the running state of the equipment is determined based on a plurality of vibration information, and the accuracy of determining the running state of the equipment is improved.
Example two
Fig. 2 is a schematic flow chart of a method for detecting an operating state of a device according to an embodiment of the present invention, where the embodiment of the present invention is a refinement of step 120 on the basis of an alternative of the foregoing embodiment, and optionally, step 120 may include: determining the operation state of the device based on the acquired vibration information at the at least two target positions and the reference vibration information at each target position, wherein step 120 may further include: and determining the running state of the equipment based on the acquired vibration information at the at least two target positions and the vibration information corresponding to the target mechanical action. The technical terms that are the same as or similar to those of the above embodiments will not be described again.
As shown in fig. 2, the method for detecting the operating state of the device according to the embodiment of the present invention includes:
s210, when the equipment vibrates, respectively acquiring vibration information of the equipment based on vibration sensors which are preset at least two target positions on the equipment.
S220, determining the running state of the equipment based on the acquired vibration information at the at least two target positions and the reference vibration information at each target position.
The reference vibration information is vibration information obtained by a vibration sensor at each target position when a target detection event of the equipment occurs in a preset normal operation state of the equipment, or vibration information preset artificially. And comparing the acquired vibration information at the at least two target positions with the reference vibration information at each target position to determine the running state of the equipment. Specifically, if the information difference obtained by comparing the current vibration information at the at least two target positions with the reference vibration information at the at least two target positions is within a preset information floating range, it may be determined that the operation state of the device is a normal operation state.
It is to be understood that the reference vibration information at different target positions may be the same or different.
Considering that the apparatus operation state may be affected by time, the vibration information at the same target detection time may be changed as time passes even though it is still in the normal operation state. Optionally, the reference vibration information is updated based on preset time information. For example, the operation of acquiring the vibration information at the corresponding target positions by the plurality of vibration sensors when the operation state of the apparatus is the normal operation state may be re-performed every a preset time period to update the reference vibration information, or the reference vibration information and the like may be updated based on the operation of adjusting the reference vibration information input by the user.
Exemplarily, a current vibration sequence is constructed based on the acquired vibration information at the at least two target positions; constructing a reference vibration sequence based on the reference vibration information at each target position; and determining the running state of the equipment according to the offset of the current vibration sequence relative to the reference vibration sequence.
The vibration sensors at different target positions are sequenced in a mode of distance between the target position corresponding to the vibration sensor and a target detection event, or time for the vibration sensor to acquire vibration information, or sequencing of the vibration sensors is manually set. The vibration sequence is formed by combining the vibration information acquired by the sequenced vibration sensors into a vibration sequence. Similarly, the reference vibration sequence is a sequence of preset vibration information. And constructing a current vibration sequence according to the obtained vibration information of at least two target positions, then comparing the current vibration sequence with a reference vibration sequence to obtain the offset of the current vibration sequence and the reference vibration sequence, and determining whether the running state of the equipment is abnormal or not based on the offset.
Illustratively, the vibration information includes vibration time and/or vibration amplitude; the determining the operation state of the equipment according to the offset of the current vibration sequence relative to the reference vibration sequence comprises at least one of the following steps:
calculating a time difference value between the vibration time at the at least one target position in the current vibration sequence and a reference vibration time at the same target position in the reference vibration sequence, and determining the running state of the equipment based on the time difference value; and calculating the amplitude difference value between the vibration amplitude at the at least one target position in the current vibration sequence and the reference vibration amplitude at the same target position in the reference vibration sequence, and determining the running state of the equipment based on the amplitude difference value.
The preset time difference range refers to a range of a time difference between the vibration time acquired at the target position and the reference vibration time at the same target position. Similarly, the preset amplitude difference range refers to a range of an amplitude difference between the vibration amplitude obtained at the target position and the reference vibration amplitude at the same target position. And calculating a time difference value between the vibration time at least one target position in the current vibration sequence and the reference vibration time at the same target position in the reference vibration sequence, and if the time difference value is within a preset time difference value range, determining that the running state of the equipment is normal. And similarly, calculating an amplitude difference value between the vibration amplitude at least one target position in the current vibration sequence and the reference vibration amplitude at the same target position in the reference vibration sequence, wherein if the amplitude difference value is within a preset amplitude difference value range, the running state of the equipment is normal. It should be understood that the time difference or the amplitude difference refers to a value after absolute value processing, and whether the time difference after absolute value processing is within a preset time difference range or not is determined, and similarly, whether the amplitude difference after absolute value processing is within a preset amplitude difference range or not is determined. When any time difference value is not in the corresponding preset time difference value range or any amplitude difference value is not in the preset amplitude difference value range, the abnormal operation state of the equipment and/or the vibration sensor is preliminarily determined, then whether the sensor at the corresponding target position with the time difference value not in the preset time difference value range is abnormal or not is determined, and further whether the equipment is abnormal or not is determined. The determination of whether the operation state of the equipment is abnormal or not by the vibration amplitudes and the vibration times acquired by the vibration sensors at the plurality of target positions is more accurate than the determination of the operation state of the equipment by the vibration amplitudes acquired by the vibration sensors at a single position. And when the vibration sensor breaks down, the problem that the detection result is inaccurate due to the failure of the vibration sensor can be found at the first time. Of course, the preset time difference range may be replaced by a preset time difference, and similarly, the preset amplitude difference range may be replaced by a preset amplitude difference. Whether the judgment time difference value is within the range of the preset time difference value or not can be replaced by judging whether the judgment time difference value is smaller than the preset time difference value or not, and similarly, whether the amplitude difference value is smaller than the preset amplitude difference value or not is judged.
And S230, determining the running state of the equipment based on the acquired vibration information at the at least two target positions and the vibration information corresponding to the target mechanical action.
Wherein a target mechanical action causing the device to vibrate is first determined; the target mechanical action is an operation that the original operation state of the device is changed through mechanical operation, for example, a closing operation of a circuit breaker. Target mechanical action and vibration information corresponding to the target mechanical action are preset. When the equipment vibrates, firstly, whether the action causing the equipment to vibrate is a target mechanical action is determined, when the action is determined to be the preset target mechanical action, the running state of the equipment is determined based on the obtained vibration information at least two target positions and the vibration information corresponding to the target mechanical action, whether the current vibration information is matched with the vibration information of the target mechanical action is determined in a targeted mode, and the accuracy of determining the running state of the equipment is improved.
Illustratively, the vibration information includes vibration time and/or vibration amplitude; the determining the operation state of the device based on the acquired vibration information at the at least two target positions and the vibration information corresponding to the target mechanical action includes at least one of the following:
if the obtained vibration time at the at least one target position is not in the vibration time range corresponding to the target mechanical action, determining that the running state of the equipment is an abnormal state; and if the obtained vibration amplitude of the at least one target position is not in the vibration amplitude range corresponding to the target mechanical action, determining that the running state of the equipment is an abnormal state.
The vibration time range refers to a vibration time range corresponding to a preset target mechanical action and not distinguishing a target position, and the vibration amplitude range refers to a vibration amplitude range corresponding to a preset mechanical action and not distinguishing a target position. And after the vibration time is acquired at different target positions, determining whether the vibration time at least one target position is not in the vibration time range corresponding to the target mechanical action, and determining that the equipment is abnormal when the vibration time is determined not to be in the vibration time range corresponding to the target mechanical action. Similarly, when the vibration amplitude at least one target position is determined not to be in the vibration amplitude range corresponding to the target mechanical action, the vibration amplitude is determined not to be in the vibration amplitude range corresponding to the target mechanical action, and the equipment is determined to be abnormal.
For example, when it is determined that the vibration time of the at least one target position is not within the vibration time range of the target mechanical action or the vibration amplitude of the at least one target position is not within the vibration amplitude range of the target mechanical action, it may now be preliminarily determined that the operation state of the apparatus is abnormal and/or the operation state of the vibration sensor at the target position is abnormal, and at this time, it is detected whether the vibration sensor at the target position is abnormal, and it is further determined whether the operation state of the apparatus is abnormal.
According to the technical scheme provided by the embodiment of the invention, the vibration information of the equipment is respectively acquired through the vibration sensors at the at least two target positions, the running state of the equipment is determined based on the vibration information at the at least two target positions and the reference vibration information at each target position, or the target mechanical action causing the equipment to vibrate is determined, and the running state of the equipment is determined based on the acquired vibration information at the at least two target positions and the vibration information corresponding to the target mechanical action. According to the technical scheme of the embodiment of the invention, the vibration information is obtained based on the vibration sensors at different target positions and is compared with the reference vibration information or the vibration information corresponding to the target mechanical action to judge the running state of the equipment, so that the accuracy of determining the running state of the equipment can be improved.
EXAMPLE III

The method comprises the steps that a vibration sensor is respectively arranged at a plurality of target positions of the circuit breaker, such as a panel, the middle part of a chassis, a frame of the circuit breaker, a contact arm and the like, so that vibration information of the circuit breaker when target detection events such as closing, opening and energy storage occur is collected. When the breaker normally operates, target mechanical action is carried out on the breaker, such as closing operation, vibration amplitude and vibration time are obtained by vibration sensors located at different target positions, and the vibration time is recorded as t1、t2、t3…, from t1、t2、t3… form a vibration time sequence determined as a reference vibration time sequence, and the vibration amplitudes are respectively recorded as s1、s2、s3…, from s1、s2、s3… form a vibration amplitude sequence to be determined as a reference vibration amplitude sequence. In the actual operation process, the breaker is switched on, vibration sensors located at different target positions acquire vibration time and vibration amplitude generated by the switching on operation, and the vibration time sequence is recorded as t'1、t′2、t′3…, the vibration amplitude sequences are respectively recorded as s'1、s′2、s′3… are provided. And when the offset of the acquired time series and the reference vibration time series is larger than a set normal value, determining that the equipment operation state is abnormal, namely delta t ═ t'i-tiAnd | is greater than sigma, wherein sigma is a set normal value of the offset of the reference vibration time sequence, or when the offset of the vibration amplitude sequence and the reference vibration amplitude sequence is greater than the set normal value, the equipment state is determined to be abnormal. That is,. DELTA.s ═ s'i-siAnd | is greater than delta, wherein delta is a set normal value of the offset of the reference vibration amplitude sequence.
The embodiment of the invention acquires the vibration time and the vibration amplitude of the vibration generated by the mechanical action of the same target of the equipment by using the vibration sensors at different target positions, judges whether the running state of the equipment is abnormal or not by utilizing the different amplitudes acquired by the position difference of the vibration sensors and the different time for acquiring the amplitudes.
