The invention discloses a remote monitoring apparatus. Various sensors are provided inside a control panel, and on the basis of the data obtained from the sensors, whether or not the atmosphere within the control panel is abnormal is judged.
Long-distance monitorng device
The present invention relates to a kind of can to the such switch board of for example shop equipment electronic control cabinet of monitored object arrange environment, with its away from the long-distance monitorng device monitored of place.
Usually, in the sensing system that is attached to electronic installation, there is following supervisory system: its position of having determined in advance the position that will measure and observed anomaly in object apparatus is placed sensor and only collects predetermined information, has patent documentation 1, patent documentation 2 as the example.
In addition, as thering is the example that its reason is carried out the supervisory system of definite function in the time that electronic-controlled installation is abnormal, can enumerate Japanese patent laid-open 5-223867 " electromagnetic environment measuring appliance ".
Patent documentation 1: Japanese patent laid-open 10-227400 " long distance control system "
Patent documentation 2: Japanese patent laid-open 5-223867 " electromagnetic environment measuring appliance "
The long-time use after new importing due to the electronic housing that comprises electronic-controlled installation and motor drive or driving cabinet (hereinafter referred to as " cabinet "); therefore compared with when it arranges the environment of periphery and arranged originally, various variations often can occur, and this just becomes fault and abnormal reason.
1) if power lead becomes the noise for signal wire near being layed in control signal wire.
2) thus because power line is by becoming the noise for the power supply of electronic-controlled installation near electronic housing.
3) if inverter apparatus becomes the noise for supply unit and control signal wire near being arranged at electronic housing.
4) noise that driving cabinet produces hinders control and the communication function of self.
5) follow the equipment of vibration to become the failure cause for the conditional equipment of vibration if be provided with, or become the loose contact reason at signal connecting element place.
6) if thereby air-conditioning changes when humidity is low and easily to produce the electric discharge causing because of static and directly destroy electronic-controlled installation, thereby and temperature when high the timing of electronic devices and components change the impact that is easily subject to noise.
In the case of causing cabinet to produce fault because of such environmental change and stopping, be difficult to judge that this fault is because the occurrent fault of the components and parts of constituent apparatus causes, or due to the former of set environment thereby produce components and parts fault and misoperation.For example make electronic-controlled installation breaks down, can expect following many reasons in the variation of direct supply voltage using when controlling: thereby make the electrolytic solution evaporation of the smmothing capacitor of supply unit accelerate to cause to pulse because temperature is high, in inputting, to sneak into the grounding of noise and supply unit insufficient thereby pulse, cause because supply unit ground connection is not good the caused fault of electromagnetic wave that electric power storage electric charge produces in aerial discharge in the time that humidity declines etc. at DC outgoing side for increase, induced noise AC overlapping with power supply output, power supply.In addition, even noise also can expect because of the caused noise of induction current, inverter that motor action causes, because the conducting of relay and switch disconnects the induced noise that produces etc., all different for any one counter-measure of taking wherein.
If it is the abnormal occurrence that can often observe, can the analyzers such as common oscillograph be installed suitable probe and measured the physical quantity of its environment, can determine the environment that becomes its reason, implement counter-measure, and confirm effect.But, for example in electronic-controlled installation action, the action of outside high voltage contact etc. and the transient noise that causes exert an influence, having its occurrence frequency is the situation below once a year.
In order to observe exactly such fault, need to monitor for a long time, and need to may become the multiple main causes of multiple Site Determinations of reason.
And about the mensuration of environment that becomes main cause, also need to add and change its determination object and measure position.
In addition, even if self does not also reach abnormality electronic-controlled installation and drive unit, but in the case of being subject to certain impact because cause controlling power supply from outside noise and vibration, or this affects in meeting becomes greatly the sign that can regard " extremely producing reserves " as situation along with the process of time, thereby also need to be helped in advance reply by illustrating.
On the environmental data of measuring even if sensor is set, in the supply voltage of electronic-controlled installation or drive unit (hereinafter referred to as " device ") self and ground current, there is can not cause the variation of that level of plant failure, sometimes also can make device access the instantaneous bus that detects by IO abnormal and recover normal by retry, or storer produces 1 bit-errors, utilize ECC function to recover, thereby or disk apparatus extremely replaces ring processing because sector occurs in the impacts such as vibration.Although these situations in this moment for device and Yan Buhui brings serious abnormal but still can give its pressure, initiating failure in the future.For this disappointing (body blow) once environmental element also want help find find just need to be got rid of.
Even the in the situation that of there is certain variation in addition on environmental data, in the state of the control voltage of measured device and ground current, electric substrate temperature or the IO bus that detects in inside, cannot confirm especially abnormal, also can produce the output reversion of moment or the transient fault of generation impact damper IC for the impact of the timing in electronic logic circuit, it can produce " less desirable control result " in processing controls sometimes.In this case, aspect maintenance, also need: by making the information such as the variation of environmental data and the control voltage of device, installing the information of the inner IO bus error detecting and installing the abnormal information of self and the time serial message mixed display of processing, thereby can be confirmed whether there is certain relation etc. with this " less desirable control result ".
Patent documentation 1 has been recorded the sensing system that the physical quantity by control object that common control device is controlled is measured, the such communication unit of multiple supervising devices that it comprises host CPU and has sensor.Being characterized as of this invention, being arranged at on-the-spot supervising device communicates with host CPU in being undertaken by other supervising device then, transmit order by wireless to supervising device successively from host CPU, host CPU is monitored and is studied the data of sending successively from each supervising device, by data or its result output display on CRT.Supervising device is arranged at multiple monitored object, and starts to be arranged in order and to communicate one by one from approaching the supervising device of CPU.As an one embodiment, record a supervising device of the device of monitoring pipeline, supervising device is provided with the various sensors such as ITV, pressure transducer, temperature sensor, vibration transducer, sound transducer, strainmeter.
This device is located at a supervising device by multiple sensors and is made it transmit information by wired or wireless to host CPU, but its object is, be sent in merely the physical quantity at the position of this mensuration, or send the process data obtaining according to the computing between the multiple physical quantitys that observe there, and cannot infer as follows:, a certain physical quantity observing there has in abnormal situation this abnormal reason from where; The physical quantity that observed there, the measured value that for example, whether can supervise the somewhere of control device to other by its measured phenomenon while there is electromagnetic sensor in this supervising device are brought impact.This is because supervising device is to be configured along definite monitored object, cannot process following situation:, in monitored object, produce from its reason the impact of environment in the place away from object, particularly as be not along definite monitored object but bring impact by a certain space electromagnetic wave or heat.To infer this environmental data to controlling the structure of self bringing what kind of impact owing to not having in addition.
Patent documentation 2 has been recorded the abnormal of electronic-controlled installation and has been carried out definite sensing system from the reason of its environment.Particularly, formed by following sensor, the abnormality detection trigger pip of the sensor of this sensor based on whether the building of holding electronic-controlled installation and this electronic-controlled installation are occurred extremely to detect, and take caused extremely as prerequisite because of external electromagnetic interference ripple, measure electromagnetic interference wave and it is determined.Can be according to triggering store electricity electromagnetic wave interference in this sensing system, and obtain the Wave datas such as its waveform, its peak value, frequency component, more than predefined level wave number.Utilize this system to determine making this electronic-controlled installation produce abnormal electromagnetic interference wave is for example because the sparetime is wireless or CB is wireless caused.
But, cannot determine the mains ripple that produces the power supply unit that abnormal reason possibility is electronic-controlled installation; Or the induced noise that is arranged in other place of building occur source or the noise of diverse building via power supply, produce as with the situation of disturbing electromagnetic wave phase phenomenon together; Or interference electromagnetic wave produces extremely electronic-controlled installation in air or along signal wire; Or the impact of Yin Wendu and vibration and the electromagnetic impact etc. that is easily interfered.This is because this mensuration cannot be carried out in the inside at this electronic-controlled installation.Although do not express in addition but as its reason, be owing to disturbing electromagnetic wave measuring apparatus larger, being not only building, and cannot being arranged on the inside of electronic-controlled installation.

Embodiment 4 is described with Fig. 2, Fig. 8.
The explanation of Fig. 2 is identical with embodiment 1, therefore omit.
Then, the electromagnetic wave noise input that is arranged near the direct motor drive inverter power supply device not shown cabinet or in cabinet is sneaked in cabinet via AC power supplies, thereby there is the situation of abnormal output in the power supply of the reason electronic-controlled installation that the ground connection that this noise is line filter is not good, action is described.
If electromagnetic wave noise is sneaked into AC power supplies, the voltage sensor 80 of AC power supplies detects this situation and sends to wireless repeater sensor 90.The current data detecting is sent to wireless repeater sensor 90 by near electromagnetic sensor 91 electric acceptance division in addition.
In this case, although the noise of sneaking into AC power supplies via noise filter 31, ground wire 36 and ground rod 40 loose contacts, noise current can not flow to ground wire 41 via ground rod 40.Because the noise in ac power cable is unattenuated, therefore the voltage sensor 51,61 of the outgoing side of noise filter 31 detects with abnormal threshold value and information is sent to wireless repeater sensor 90.For the noise of sneaking into from AC electricity acceptance division, further utilize the voltage sensor 52,62 of the efferent of supply unit 11,12 detect abnormal voltage and these data are sent to wireless repeater sensor 90.The current waveform detecting as abnormal rank is sent to wireless repeater sensor 90 by near electromagnetic sensor 92,93 electronic-controlled installation 10,20 simultaneously.
Although now the ground current sensor 73 of noise filter does not detect whatever, the noise current causing because of wave filter effect of 71,72 pairs of power supplys of ground current sensor of the supply unit of electronic-controlled installation 20 detects and sends to wireless repeater sensor 90.
Other electromagnetic sensor 92,93 also sends to wireless repeater sensor 90 by some information.
Wireless repeater sensor 90 sends to the data of the temperature in cabinet, humidity, vibration the not shown PC that infers flow process of execution graph 4, and the data that exceed each threshold value that detected by each sensor are sent to PC.
In PC, infer abnormal position with the algorithm example shown in Fig. 8.
According to the abnormal data in the voltage sensor 80 in AC electricity acceptance division, detect AC power supplies abnormal (S1), outputed to PC picture (S2).
