Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a method and device for monitoring the energy efficiency of electrical equipment, a non-contact tag and a medium. Background Art

[0002] Medical equipment is an indispensable hardware condition in hospitals. The utilization rate of medical equipment such as ultrasonic diagnostic equipment, ventilators, and endoscopes directly affects the hospital's management costs and procurement decisions. At present, many medical equipment in hospitals are charged according to the number of times they are used, so hospitals need to have the requirement to detect the usage status (off / standby / operation) of medical equipment. In order to meet this requirement, there are mainly two types of tags on the market, one is an access tag and the other is a non-access tag. Among them, the access tag needs to change the power supply environment of the medical equipment, which will have a certain impact on the operation of the medical equipment. In severe cases, it may cause the medical equipment to be powered off or short-circuited, causing economic losses and personnel safety issues; while the non-access tag can be pasted on the surface of the medical equipment, and the use status of the medical equipment can be judged by the change of the magnetic field. It will not affect the equipment itself and is safe and reliable.

[0003] Monitoring principle of non-access tags: When the medical device is running, a current is generated in the closed circuit, and the conductor passing through it has a magnetic field. The non-access tag is placed in the magnetic field, and an alternating magnetic field in the same direction is applied at the same time. When induced eddy currents are generated inside the non-access tag, these eddy currents will generate Lorentz forces under the action of the magnetic field, causing mechanical vibrations to occur locally inside the non-access tag. Mechanical vibrations will excite sound waves with the same frequency as the magnetic field, which are then picked up by devices such as ultrasound probes inside the non-access tag. By analyzing and processing these sound wave signals, the conductivity distribution of the medical device can be reconstructed to evaluate its usage status.

[0004] However, the accuracy of traditional non-access tag monitoring data is easily affected by factors such as medical equipment power consumption, other equipment, poor grounding, and human touch, which affects the accuracy of magnetic field and conductivity, and thus affects the accuracy of energy efficiency monitoring of medical equipment.

[0051] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0053] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0054] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0055] In order to solve the above problems, this embodiment relates to a method for monitoring the energy efficiency of electrical equipment, which is applied to a non-contact tag, wherein a plurality of monitoring sensors with different installation positions or angles are arranged in the non-contact tag, and the non-contact tag is attached to the surface of the electrical equipment to be monitored. In this embodiment, the monitoring sensor can be, but is not limited to, a mechanical vibration sensor. The electrical equipment to be monitored can be, but is not limited to, medical equipment, such as ultrasonic diagnostic equipment, ventilator, endoscope and other electrical equipment.

[0056] It should be noted that the electrical equipment mentioned in the present invention is equipment that needs to be plugged in, such as an ultrasonic diagnostic instrument.

[0057] The following is an explanation of the implementation details of the method for monitoring energy efficiency of electrical equipment according to the first embodiment of the present invention. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

[0058] The specific process of this implementation is as follows: Figure 1 As shown, specifically including:

[0059] Step S100, determining a main processing unit and a plurality of secondary processing units among a plurality of monitoring sensors;

[0060] It should be understood that the contactless tag is attached to the surface of the electrical equipment to be monitored. When the same contactless tag is installed on the same electrical equipment to be monitored, the magnetic induction received by each corresponding processing unit will also change when the installation position or angle is different. For example, the same contactless tag can be installed on the back of the same electrical equipment to be monitored, or at the power connection point. The magnetic induction received by each corresponding processing unit will also change with the different installation positions; for another example, the same contactless tag is installed at the same position of the same electrical equipment to be monitored but at different installation angles, the magnetic induction received by each corresponding processing unit will also change. By determining a main processing unit and multiple secondary processing units in multiple monitoring sensors each time, the contactless tag can be adapted to different environments.

[0061] It should be noted that the number of sub-processing units is at least two, so that multiple sub-processing units can be associated and verified. In addition, when the monitoring data of multiple sub-processing units have not changed, it is considered that the monitoring data of the sub-processing units has not changed; when only part of the monitoring data of multiple sub-processing units has not changed, it is considered that the monitoring data of the sub-processing units has changed.

[0062] In a specific implementation, in response to a change in the installation position or installation angle of the non-access tag, a main processing unit and a plurality of sub-processing units in a plurality of monitoring sensors are re-determined.

[0063] When the installation position or installation angle of the non-access tag changes, the magnetic induction received by each monitoring sensor will also change. For example, the data received by the monitoring sensor near the power port will be more accurate. In this case, the monitoring sensor near the power port will be determined as the main processing unit.

[0064] Similarly, when the installation angle changes, the magnetic induction received by each monitoring sensor will also change. Therefore, each time the installation position or installation angle of the non-access tag changes, re-determining a main processing unit and multiple secondary processing units in multiple monitoring sensors can effectively improve the monitoring accuracy and improve the adaptability of the non-contact tag.

[0065] Furthermore, after the non-access tag is installed and enabled, the constant magnetic flux voltage values ​​of the main processing unit and the plurality of sub-processing units are initialized as reference values. Taking medical equipment as an example of electrical equipment, the magnetic flux voltage values ​​corresponding to the medical equipment status exist in a certain interval range. Under the premise of eliminating common interference, after the non-access tag is installed and enabled, the reference values ​​of each processing unit can be initialized, so that each reference value can be updated when the installation position of the non-access tag changes.

[0066] Step S200, receiving monitoring data of the main processing unit and multiple secondary processing units;

[0067] It should be understood that, taking the main processing unit and the plurality of sub-processing units as vibration sensors as an example, the monitoring data of the main processing unit and the plurality of sub-processing units are generally magnetic flux voltage values.

[0068] Step S300: determining the current usage status of the electrical equipment to be monitored according to the changes in the monitoring data of the main processing unit and the plurality of sub-processing units.

[0069] It should be understood that usually the electrical equipment to be monitored itself will be equipped with a monitoring unit, but when it is disturbed by external interference or people touching the electrical equipment to be monitored, it is easy to be affected by external interference. By setting a main processing unit and multiple sub-processing units, and through the correlation verification of the monitoring data of the main processing unit and multiple sub-processing units, the non-contact tag can shield the misjudgment of the use of the electrical equipment to be monitored due to local interference of the electrical equipment to be monitored. The current use status of the electrical equipment to be monitored may be normal or abnormal.

[0070] It should be noted that the current usage status of the electrical equipment to be monitored is determined based on the changes in the monitoring data of the main processing unit and the multiple sub-processing units, that is, the changes in the monitoring data of the main processing unit are correlated and verified with the changes in the monitoring data of the multiple sub-processing units, and finally it is determined that the current usage status of the electrical equipment to be monitored is normal or abnormal.

[0071] The main processing unit is usually identified as the processing unit that receives the magnetic induction most accurately, followed by the secondary processing unit. However, the present invention does not directly use the monitoring data of the main processing unit to monitor the current use status of the monitored electrical equipment, but rather associates the monitoring data of the main processing unit with the monitoring data of the secondary processing unit for verification, so that the monitored electrical equipment can be better shielded from interference caused by power consumption, other equipment, poor grounding, human touch and other factors.

[0072] In a specific implementation, determining the current usage status of the electrical equipment to be monitored based on the changes in the monitoring data of the main processing unit and the multiple sub-processing units includes: determining the change information of the monitoring data of the main processing unit and the multiple sub-processing units based on the baseline values ​​and monitoring data of the main processing unit and the multiple sub-processing units; determining the current usage status of the electrical equipment to be monitored based on the change information of the monitoring data of the main processing unit and the multiple sub-processing units.

[0073] In addition, when the electrical equipment to be monitored is in an abnormal state, an interference troubleshooting prompt message may be issued to remind the user.

[0074] The present invention provides a method for monitoring the energy efficiency of electrical equipment. The non-access tag is provided with a plurality of monitoring sensors with different installation positions or angles. The non-access tag is attached to the surface of the electrical equipment to be monitored. A main processing unit and a plurality of sub-processing units among the plurality of monitoring sensors are first determined; monitoring data of the main processing unit and the plurality of sub-processing units are received; and the current use state of the electrical equipment to be monitored is determined according to changes in the monitoring data of the main processing unit and the plurality of sub-processing units. Thus, the changes in the monitoring data of the main processing unit are correlated with changes in the monitoring data of the plurality of sub-processing units to finally determine whether the current use state of the electrical equipment to be monitored is a normal state or an abnormal state. This solves the problem in the prior art that the accuracy of monitoring data of traditional non-access tags is easily disturbed by factors such as power consumption of medical equipment, other equipment, poor grounding, and human touch, which affects the accuracy of magnetic field and conductivity, and further affects the accuracy of energy efficiency monitoring of medical equipment.

[0075] like Figure 2 As shown, the second implementation of the method for monitoring the energy efficiency of electrical equipment provided by the present invention is based on the first implementation, and the step S300 includes:

[0076] Step S310, determining whether the monitoring data of the main processing unit has changed;

[0077] It should be understood that when the monitoring data of the main processing unit is constant, the current usage status of the electrical equipment to be monitored is considered to be normal regardless of whether the monitoring data of the secondary processing unit changes; when the monitoring data of the main processing unit changes, it is necessary to combine the changes in the monitoring data of the secondary processing unit to judge the current usage status of the electrical equipment to be monitored, so as to avoid interference with the main processing unit and affect the non-contact tag's judgment on the current usage status of the electrical equipment to be monitored.

[0078] It should be noted that whether the monitoring data of the main processing unit has changed can be determined by comparing it with its reference value; or by obtaining the monitoring data of the main processing unit at different times for comparison and determination.

[0079] The determination of the reference value of the processing unit can be done by installing and activating the contactless tag first, excluding common interferences, and initializing the constant magnetic flux voltage value of the processing unit as the reference value. Since the magnetic flux voltage value corresponding to the medical device has a certain range, the reference value needs to be initialized under the premise of excluding common interferences.

[0080] Step S320, when the first judgment result is no, determining that the electrical equipment to be monitored is in a normal state;

[0081] It should be noted that when the first judgment result is no, it means that the monitoring data of the main processing unit has not changed.

[0082] In specific implementation, the monitoring data of the main processing unit can be compared with its corresponding reference value. When the monitoring data of the main processing unit remains the same relative to its reference value, or fluctuates within the allowed threshold range, it is considered that the monitoring data of the main processing unit has not changed. At this time, no matter how the monitoring data of the secondary processing unit changes, it is considered that the monitored electrical equipment is in a normal state.

[0083] More specifically, when the first judgment result is no, determining that the electrical equipment to be monitored is in a normal state includes:

[0084] When the first judgment result is no, and the monitoring data of the plurality of sub-processing units change, it is determined that the monitored electrical equipment is in a normal state, and the plurality of sub-processing units are in a disturbed state;

[0085] When the first judgment result is no, and the monitoring data of the plurality of sub-processing units have not changed, it is determined that the electrical equipment to be monitored is in a normal state.

[0086] Step S330: When the first judgment result is yes, the current usage status of the electrical equipment to be monitored is determined according to the changes in the monitoring data of the plurality of sub-processing units.

[0087] It should be noted that when the first judgment result is yes, that is, the monitoring data of the main processing unit has changed, the monitoring data of the main processing unit can be compared with its corresponding reference value. When the monitoring data of the main processing unit changes relative to the reference value, it is considered that the monitoring data of the main processing unit has changed. It can also be set to a threshold. When the absolute value of the difference between the monitoring data of the main processing unit and the reference value is greater than the threshold, it is considered that the monitoring data of the main processing unit has changed. At this time, it is necessary to combine the changes in the monitoring data of multiple secondary processing units to determine the current usage status of the electrical equipment to be monitored.

[0088] like Figure 3 As shown, the third implementation of the method for monitoring the energy efficiency of electrical equipment provided by the present invention is based on the second implementation, and the step S330 includes:

[0089] Step S331, when the first judgment result is yes, determining whether the change ranges of the monitoring data of the plurality of sub-processing units are all zero;

[0090] It should be understood that when the monitoring data of the main processing unit changes, it is necessary to determine whether the monitored electrical equipment is in an abnormal state or the main processing unit is disturbed based on the changes in the monitoring data of multiple secondary processing units.

[0091] Step S332, when the second judgment result is yes, determining that the electric device to be monitored is in a normal state and the main processing unit is in a disturbed state;

[0092] It should be understood that when the change range of the monitoring data of multiple sub-processing units is zero, that is, the monitoring data of multiple sub-processing units have not changed relative to their baseline values, or the change range is within a threshold range (the change is within the allowable error range), the monitoring data of multiple sub-processing units are considered constant. When the monitoring data of multiple sub-processing units are constant, it is considered that the monitored electrical equipment is in a normal state, and the main processing unit is in a disturbed state, so the monitoring data of the main processing unit can be verified by the monitoring data of the sub-processing units.

[0093] Step S333, when the second judgment result is no, judging whether the change of the monitoring data of the plurality of sub-processing units is an increase or decrease of the same magnitude year-on-year;

[0094] It should be understood that when the monitoring data of multiple sub-processing units changes, it is necessary to determine whether the sub-processing units are disturbed based on the change amplitude of the monitoring data of the multiple sub-processing units. When the change of the monitoring data of multiple sub-processing units is an increase or decrease of the same amplitude year-on-year, it is considered that the sub-processing units are in a normal state and the electrical equipment to be monitored is in a normal state; otherwise, it is considered that the electrical equipment to be monitored is in an abnormal state.

[0095] Step S334, when the third judgment result is no, determining that the electrical equipment to be monitored is in an abnormal state;

[0096] It should be understood that when the third judgment result is no, that is, the change in the monitoring data of multiple sub-processing units is not an increase or decrease at the same rate as the same period last year, for example, the sub-processing units include V1 and V2, when V1 changes from 50V to 100V, and V2 changes from 30 to 800, the growth rate relative to the baseline value is very different, then it is considered that the change in the monitoring data of multiple sub-processing units is not an increase at the same rate as the same period last year.

[0097] Step S335: when the third judgment result is yes, it is determined that the electrical equipment to be monitored is in a normal state and the main processing unit is in a disturbed state.

[0098] It should be understood that when the third judgment result is yes, the change in the monitoring data of multiple sub-processing units is an increase or decrease of the same magnitude year-on-year. For example, the sub-processing units include V1 and V2. When V1 changes from 50V to 55V, and V2 changes from 30 to 33, the growth rate relative to the baseline value is the same or similar, then it is considered that the change in the monitoring data of multiple sub-processing units is an increase of the same magnitude year-on-year.

[0099] In order to achieve the above object, the present invention also provides a monitoring device for energy efficiency of electrical equipment, which is applied to a non-contact tag, wherein the non-contact tag is provided with a plurality of monitoring sensors with different installation positions or angles, and the non-contact tag is attached to the surface of the electrical equipment to be monitored, such as Figure 4 As shown, the monitoring device includes a determination unit 410, a receiving unit 420, and a judgment unit 430, wherein:

[0100] The determination unit 410 is used to determine a main processing unit and a plurality of secondary processing units in a plurality of monitoring sensors;

[0101] It should be understood that the contactless tag is attached to the surface of the electrical equipment to be monitored. If the same contactless tag is installed on the same electrical equipment to be monitored, the magnetic induction received by each corresponding processing unit will also change with different installation positions or angles. For example, if the same contactless tag is installed on the back of the same electrical equipment to be monitored or at the power connection, the magnetic induction received by each corresponding processing unit will also change with different installation positions; for another example, if the same contactless tag is installed at the same position of the same electrical equipment to be monitored but at different installation angles, the magnetic induction received by each corresponding processing unit will also change. By determining a main processing unit and multiple secondary processing units in multiple monitoring sensors each time, the contactless tag can be adapted according to different environments.

[0102] It should be noted that the number of sub-processing units is at least two, so that multiple sub-processing units can be associated and verified. For example, when the monitoring data of multiple sub-processing units have not changed, it is considered that the monitoring data of the sub-processing units has not changed; when only part of the monitoring data of multiple sub-processing units has not changed, it is considered that the monitoring data of the sub-processing units has changed.

[0103] In a specific implementation, in response to a change in the installation position or installation angle of the non-access tag, a main processing unit and a plurality of sub-processing units in a plurality of monitoring sensors are re-determined.

[0104] When the installation position or installation angle of the non-access tag changes, the magnetic induction received by each monitoring sensor will also change. For example, the data received by the monitoring sensor near the power port will be more accurate. In this case, the monitoring sensor near the power port will be determined as the main processing unit.

[0105] Similarly, when the installation angle changes, the magnetic induction received by each monitoring sensor will also change. Therefore, each time the installation position or installation angle of the non-access tag changes, re-determining a main processing unit and multiple secondary processing units in multiple monitoring sensors can effectively improve the monitoring accuracy and improve the adaptability of the non-contact tag.

[0106] Furthermore, after the non-access tag is installed and enabled, the constant magnetic flux voltage values ​​of the main processing unit and the plurality of sub-processing units are initialized as reference values. Taking medical equipment as an example of electrical equipment, the magnetic flux voltage values ​​corresponding to the medical equipment status exist in a certain interval range. Under the premise of eliminating common interference, after the non-access tag is installed and enabled, the reference values ​​of each processing unit can be initialized, so that each reference value can be updated when the installation position of the non-access tag changes.

[0107] The receiving unit 420 is used to receive monitoring data of the main processing unit and multiple secondary processing units;

[0108] It should be understood that, taking the main processing unit and the plurality of sub-processing units as vibration sensors as an example, the monitoring data of the main processing unit and the plurality of sub-processing units are generally magnetic flux voltage values.

[0109] The judgment unit 430 is used to determine the current usage status of the electrical equipment to be monitored according to the changes in the monitoring data of the main processing unit and the plurality of sub-processing units.

[0110] It should be understood that usually the electrical equipment to be monitored itself will be equipped with a monitoring unit, but it is easy to be interfered by the outside world or when people touch the electrical equipment to be monitored. By setting up a main processing unit and multiple sub-processing units, and through the correlation verification of the monitoring data of the main processing unit and multiple sub-processing units, the non-contact tag can shield the misjudgment of the use of the electrical equipment to be monitored due to local interference of the electrical equipment to be monitored. The current use status of the electrical equipment to be monitored may be normal or abnormal.

[0111] It should be noted that the current usage status of the electrical equipment to be monitored is determined based on the changes in the monitoring data of the main processing unit and the multiple sub-processing units, that is, the changes in the monitoring data of the main processing unit are correlated and verified with the changes in the monitoring data of the multiple sub-processing units, and finally it is determined that the current usage status of the electrical equipment to be monitored is normal or abnormal.

[0112] The main processing unit is usually identified as the processing unit that receives the magnetic induction most accurately, followed by the secondary processing unit. However, the present invention does not directly use the monitoring data of the main processing unit to monitor the current use status of the monitored electrical equipment. By correlating the monitoring data of the main processing unit with the monitoring data of the secondary processing unit for verification, the interference of the monitored electrical equipment due to power consumption, other equipment, poor grounding, human touch and other factors can be better shielded.

[0113] In a specific implementation, determining the current usage status of the electrical equipment to be monitored based on the changes in the monitoring data of the main processing unit and the multiple sub-processing units includes: determining the change information of the monitoring data of the main processing unit and the multiple sub-processing units based on the baseline values ​​and monitoring data of the main processing unit and the multiple sub-processing units; determining the current usage status of the electrical equipment to be monitored based on the change information of the monitoring data of the main processing unit and the multiple sub-processing units.

[0114] In addition, when the electrical equipment to be monitored is in an abnormal state, an interference troubleshooting prompt message may be issued to remind the user.

[0116] The memory 502 and the processor 501 are connected in a bus manner, and the bus may include any number of interconnected buses and bridges, and the bus connects various circuits of one or more processors 501 and the memory 502 together. The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices on a transmission medium. The data processed by the processor 501 is transmitted on a wireless medium via an antenna, and further, the antenna also receives data and transmits the data to the processor 501.

[0117] The processor 501 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management and other control functions. The memory 502 can be used to store data used by the processor 501 when performing operations.

[0118] In order to achieve the above object, the present invention provides a computer-readable storage medium storing a computer program, which implements the above method for monitoring the energy efficiency of electrical equipment when executed by a processor.

[0119] That is, those skilled in the art can understand that all or part of the steps in the above-mentioned implementation method can be completed by instructing the relevant hardware through a program, and the program is stored in a storage medium, including a number of instructions to enable a device (which can be a single-chip microcomputer, chip, etc.) or a processor to execute all or part of the steps of the method described in each implementation of the present application. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk and other media that can store program codes.

[0120] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
