Description
Technical Field
The invention relates to the field of monitoring of electronic measuring instruments, in particular to a system suitable for monitoring the health state of an electronic measuring instrument.
Background
The electronic measuring instrument is a heavy asset in the fields of electronic manufacturing, aerospace, national defense, military industry and the like, and the efficient management of the electronic measuring instrument becomes an important factor for realizing the business target and innovation management of an organization. The key contents of instrument asset management comprise instrument fault monitoring, instrument working condition abnormal condition monitoring and the like, and the instrument asset management method is an important means for ensuring the effectiveness and credibility of instrument work. For instrument failure conditions, built-in self-test (BIT hereinafter) provides some data, but lacks a field monitoring device that can be tightly integrated with the instrument. And the information provided by the instrument BIT often indicates that a serious fault has occurred, but an abnormality may have occurred before the serious fault in a certain period of time, but a relevant trend or sign cannot be found in time, so that the serious fault of the instrument is caused, and the validity of the test data of the instrument cannot be guaranteed in the period of time, so that the validity of relevant business activities is influenced. Meanwhile, because the measurement parameters of the electronic measurement instrument are mainly parameters in the electromagnetic field, strict requirements are imposed on the electromagnetic environment of the space where the electronic measurement instrument is located, and for example, in the working process of the instrument, the monitoring equipment should not introduce additional electromagnetic radiation influence so as not to influence the test result. The internet of things gateway for the monitoring instrument is generally developed for a general purpose at present, and the internet of things gateway aiming at the working mode and the characteristics of the electronic measuring instrument is still lacked.
Health state monitoring of electronic measuring instruments is an important means for ensuring factors such as instrument usability, instrument test result consistency and instrument state stability, and is described by data in multiple fields, including information such as metering period, environment information, instrument BIT data, instrument internal temperature and instrument use load. Generally, according to the parameter range specified by the working technical conditions of the instrument, if a certain parameter exceeds the standard, an alarm is generated. Currently available methods include: (1) monitoring BIT information of the instrument, and performing alarm processing on abnormal information; (2) monitoring the voltage, current and real-time power of the instrument to identify power supply abnormality or instrument power abnormality; (3) monitoring whether the temperature and the humidity of the environment where the instrument is located are abnormal or not; (4) monitoring the vibration of the instrument, and performing alarm processing on larger vibration; (5) and (4) performing fault prediction by using instrument big data.
The following detailed description is given:
(1) monitoring the built-in self-test information of the instrument: this is currently the most common means of monitoring the health of an instrument. The self-test information in the instrument is based on the testability design circuit in the instrument, and the internal fault condition of the instrument can be effectively reflected. However, for most instruments, the coverage of internal self-test is insufficient, only some typical faults are monitored, and the internal self-test information reflects more important faults. The indexes that cannot be covered by the self-test design cannot be used.
(2) The voltage current and real-time power of the instrument are monitored. If power supply abnormality or instrument power abnormality is identified, the power supply is generally required to be processed, or the internal working state of the instrument is checked, the reason is confirmed, and targeted processing is performed. The method has great limitation, after all, the abnormal electricity utilization is only one of abnormal instruments, and the corresponding abnormal instrument information only accounts for a small part of the abnormal instrument condition.
(3) By monitoring the temperature and the humidity of the environment where the instrument is located, abnormal information is generated according to the requirements of the working environment of the instrument if the temperature or the humidity exceeds the standard. But temperature and humidity anomalies are not directly linked to the health of the instrument.
(4) The instrument was monitored for vibration. If the over-limit vibration occurs, the falling or impact of the instrument can be reflected, the health state of the instrument can be potentially influenced, and further examination and confirmation are needed. Like the temperature and humidity information, this is a reference index and is not directly linked to the health condition of the instrument.
(5) And predicting the fault of the instrument based on the big data. Based on accumulated instrument state monitoring data, certain rules and modes are excavated by machine learning and data mining technologies for fault diagnosis and fault prediction. This approach is not mature at present, because the instrument itself involves multiple disciplines such as microwave, analog circuit, digital circuit, software, mechanical structure, etc., and the fault prediction is carried out on the instrument, which lacks both marked data and mature algorithm. The method only has practical significance to individual indexes of individual instruments at present, and application scenes are limited.
