Description
Technical Field
The invention belongs to the technical field of monitoring systems, and particularly relates to a device state monitoring system supporting remote collaboration and a state reporting method thereof.
Background
The Monitoring objects of the Condition Monitoring System (CMS) and its application solution are generally critical or high-value instruments, such as numerical control machines, robots, detection equipment, process equipment, logistics storage equipment, test facilities, electrical equipment and other industrial assets. The CMS can actively, long-term and comprehensively monitor the operation related parameter indexes of the monitored object, sense the current working state and the operation parameters of the monitored object, predict the state trend, insights the symptoms of the fault occurrence, give out early warning and decision suggestions in the aspects of operation, application, maintenance, daily maintenance and the like, help a user to carry out preventive maintenance, equipment health management, maintenance and maintenance guarantee and the like, avoid abnormal shutdown or catastrophic fault of the monitored object, and further reduce the operation and maintenance cost.
Most of the existing monitoring objects at present belong to dumb terminal state instrument equipment, and equipment maintenance personnel or field management personnel cannot obtain the working state and the operating parameters of the equipment. In most cases, instrument and equipment maintenance personnel or field operating personnel can acquire instrument and equipment state data and evaluate the performance parameter index condition of the instrument and equipment by means of various modes such as manual observation comparison, auxiliary tool inspection and the like. In recent years, the degree of intellectualization, software and networking of high-end instruments and equipment is increasing. Taking an electronic measuring instrument as an example, the self-testing performance is greatly improved, a Built-In self-Test (BIT) technology is mostly adopted to realize the self-testing function, and the passing/failing/abnormal error Test of quantitative parameter indexes (such as voltage, temperature, time domain waveform and the like) can be carried out on the complete machine, software and hardware module units and even key interfaces of the electronic measuring instrument. For the execution of the self-test function, according to the different execution opportunities, the self-test function can be classified into three types: power BIT (PBIT), Continuous self test (CBIT), and Instruction self test (IBIT). The power-on self-test PBIT is automatically executed after the instrument is started, the detection items are relatively complete, and the power-on self-test PBIT relates to the state detection of a complete machine, software and hardware module units and even key interfaces; the continuous self-test CBIT is periodically and continuously executed when the instrument works normally, the normal working state of the instrument is not influenced, detection items are relatively few, and generally, simple detection is performed only aiming at key sensitive parameter indexes, and notification is displayed in time; the instruction self-test IBIT is manually executed by an operator in a mode of manual operation of an instrument panel or is remotely responded and executed by receiving a third party program control command, the detection items are relatively flexible, most instruments only perform simple tests on the self functional performance and give test result reports which can be stored and recorded. Electronic measurement instruments with an interconnection interface (LAN or USB) usually have an IBIT function: receiving and responding to a self-test command (such as ". times. TST. However, the IBIT self-test functions of these instrumentation devices typically require switching to a self-test mode for execution, interrupting or otherwise affecting the current operational state of the instrumentation devices. Strictly speaking, only the partial operating state of the instrument is indirectly reflected. The equipment maintenance support personnel and the field management personnel generally pay attention to the on-off record, the running state (on-line running, abnormal, on-line standby, shutdown, measurement and detection, maintenance), the environment state (such as position, temperature and humidity) and the performance parameter index (such as time domain waveform, amplitude and phase, standing wave ratio), and other state data, and the state data are often acquired manually on the field or a state test result report is transmitted to be acquired and responded, so that the acquired state data are not comprehensive enough, the state reporting processing is not timely, the abnormal alarm response is slow, and the automation degree is weak. In summary, the on-site status awareness capability remains insufficient.
The existing instrument and equipment state monitoring system and the application solution thereof integrate various sensing resources (such as a temperature and humidity sensor, a pressure sensor, a voltage and current sensor, a position sensor, a vision sensor, an intelligent instrument and the like), realize real-time detection of the running state of equipment and early warning, diagnosis or other maintenance decision processing on equipment faults according to equipment running parameters, generally adopt various acquisition modes (code embedding points, probe programs, triggers, data synchronization, message notification or manual assistance and the like) to acquire state data, and mainly perform control processing such as data preprocessing, record storage and analysis application (such as trend analysis, diagnosis evaluation, prediction alarm and decision processing and the like) after acquiring the state data information.
The CMS in the typical configuration mainly comprises a management center node, a browse analysis node, a data acquisition node and a communication network. Part of the CMS adopts a point-to-point (Peer-to-Peer, P2P) based mode to directly report status data, although the low latency is strong in real-time, only supports single message consumption, and is limited in application limitation. With the introduction of the publish/subscribe technology, especially, a Message Queue product based on a publish/subscribe mode is adopted, such as MQTT (Message Queuing Telemetry Transport), rabbitmq (rabbitmessage Queue, Message Queue of rabbitcompany), DDS (Data Distribution Service for Real-time system ), and the like, which has the advantages of decoupling, easy maintenance, asynchronous execution and avoidance of high load, avoids the limitation of the P2P mode, and can provide an instant response experience, thereby obtaining more and more applications in the instrument device state monitoring system.
At present, although some high-end instruments and devices have an interconnection interface and a self-testing function, working states and operating parameter conditions of the high-end instruments and devices are mostly reported manually or cooperatively by means of human-computer by field personnel, and the working states and the operating parameter conditions can be known by related personnel through regular routing inspection by equipment maintenance personnel, even abnormal faults of the equipment are down and the like. Particularly, for a multipoint monitoring and centralized processing scene (such as an electronic product digital/intelligent production workshop, an electronic equipment comprehensive environment test field or a weapon equipment logic target range) in an industrial production field or a distributed environment at different places, the phenomena of insufficient state sensing capability, such as incomplete field state sensing data information, untimely state reporting and processing, slow abnormal alarm response, weak automation degree and the like exist.
