Description

  The present invention relates to a monitoring apparatus and a monitoring method for equipment having consumable parts.

  Examples of equipment having consumable parts to be monitored include air compressors, air conditioners, general household appliances, general industrial equipment, and automobiles.

  For example, air compressors are used in various industrial fields and are said to account for about 20 to 30% of power consumption in factories.

  Air compressors use multiple consumable parts, such as a belt that transmits power between the compressor body and the motor, and a suction that is provided on the suction side of the compressor body to remove impurities in the intake air. There are a filter, lubricating oil supplied to the compressor body, a separator element that separates the lubricating oil from compressed air generated in the compressor body, and an oil filter that removes impurities in the lubricating oil. These consumable parts need to be replaced as the deterioration progresses, and if the replacement is not performed at an appropriate timing, the compression efficiency is lowered and the power consumption is increased. For this reason, manufacturers set operating hours and usage times that recommend replacement for each consumable part. However, the speed of deterioration of consumable parts varies depending on the operating environment, and the air compressor does not always deteriorate as designed. For example, there is a great difference in the deterioration speed of consumable parts between an industrial equipment manufacturing site with a lot of dust and a food manufacturing site with a relatively small amount of dust.

  As a background art in the field of the present invention, there is JP 2013-213669 A (Patent Document 1). In patent document 1, while acquiring driving information from an apparatus, the said driving information of the preset period is recorded as past driving information, the present driving information and past driving information are compared, and the comparison result The point that the failure stop time is predicted based on the above and the failure stop time is displayed is disclosed.

JP 2013-213669 A

  In Patent Document 1, a sensor is attached to an air conditioner, and the degree of deterioration of a component is calculated based on the sensed data. The parts replacement time is predicted and notified to the user.

  However, in Patent Document 1, the user is notified of the part replacement time, but the effect corresponding to the user merit such as how much power loss can be reduced by the replacement of the part is not performed. Therefore, from the user's standpoint, there is a problem that it is difficult to understand what merits they have by replacing parts.

  In order to solve the above-described problems, the present invention is, for example, a monitoring method for a monitoring apparatus that outputs information that prompts replacement of consumable parts based on a deterioration state of the consumable parts of the device, and for a certain period of time. It is configured to output the magnitude of power loss with respect to the base point.

  In the present embodiment, an air compressor will be described as an example of an application target of the monitoring device.

  FIG. 1 is an overall configuration diagram of an air compressor including a monitoring device according to the present embodiment. In FIG. 1, an oil supply type air compressor includes a compressor main body 1 that compresses air, an electric motor (motor) 3 that transmits power through a belt 2 to drive the compressor main body 1, and the electric motor 3 An inverter 4 that variably controls the rotational speed, a suction filter 5 that is provided on the suction side of the compressor body 1 to remove impurities in the intake air, a suction throttle valve 6 that is provided on the suction side of the compressor body 1, and a compression An oil tank 7 provided on the discharge side of the machine body 1 for primarily separating the lubricating oil 30 from the compressed air, a separator element 8 for secondarily separating the lubricating oil 30 from the compressed air separated by the oil tank 7, and the separator An after cooler 11 is provided for cooling by introducing compressed air separated by the element 8 through a pressure regulating valve 9 and a check valve 10.

  The lubricating oil 30 separated by the separator element 8 is supplied to the suction side of the compressor body 1. On the other hand, the lubricating oil 30 separated in the oil tank 7 is supplied to the inside of the compressor body 1 through, for example, an oil cooler 12 that cools the lubricating oil and an oil filter 13 that removes impurities in the lubricating oil. In addition, a bypass system for bypassing the oil cooler 12 is provided, and a temperature control valve 14 for adjusting a ratio of a cooling flow rate to the oil cooler 12 side and a bypass flow rate to the bypass system is provided at an upstream connection portion of the bypass system. Is provided. The temperature control valve 14 adjusts the ratio of the cooling flow rate and the bypass flow rate according to the temperature of the lubricating oil 30 from the oil tank 7, and thereby adjusts the temperature of the lubricating oil 30 supplied to the compressor body 1. The aftercooler 11 and the oil cooler 12 are air-cooled heat exchangers and are cooled by cooling air generated by the cooling fan 15.

  A pressure sensor 208 that detects the discharge pressure of the compressor body 1 is provided on the downstream side of the aftercooler 11. Then, a detection signal from the pressure sensor 208 is output to the control device 17.

  The control device 17 calculates a deviation between the discharge pressure detection value input from the pressure sensor 208 and a predetermined target value set in advance, and outputs a rotation speed command signal generated based on the deviation to the inverter 4. The inverter 4 outputs a frequency to the electric motor 3 according to the rotational speed command signal, and variably controls the rotational speed of the electric motor 3.

  A differential pressure sensor 202 is attached to the suction filter 5, and the state of clogging of the suction filter 5 can be detected from the differential pressure inside and outside the suction filter 5.

  A contamination sensor 204 is attached to the oil tank 7, and it is possible to detect the state of contamination of the lubricating oil 30 in the oil tank.

  The separator element 8 is provided with a differential pressure sensor 206 and can detect a clogging state from the differential pressure inside and outside the element.

  The monitoring device 100 is connected to these sensors 202, 204, and 206, acquires measurement results, and can grasp the deterioration status of the suction filter 5, the lubricating oil 30, and the separator element 8 from the respective measurement results. .

  Next, the configuration of the monitoring apparatus 100 will be described with reference to FIG. In FIG. 2, the monitoring device 100 includes a communication unit 102, a deterioration degree calculation unit 104, a deterioration degree storage unit 106, an event storage unit 108, an event management unit 110, a replacement time estimation unit 112, and a display content switching. Unit 114, energy saving effect estimation unit 116, energy saving contribution DB 118, input unit 120, and output display unit 122.

  The communication unit 102 receives various sensor data of the air compressor and signals from the measurement unit. For example, it is connected to sensors 202, 204, and 206 for detecting the deterioration status of consumable parts such as the suction filter 5, and receives a measurement signal. The communication unit 102 is connected to the operating time measuring unit 50 that measures the operating time of the air compressor and receives operating time information, and is connected to the power measuring unit 60 and receives the power consumption of the air compressor.

  The deterioration level calculation unit 104 receives the signal of the sensor attached to the consumable part from the communication unit 102, and calculates the deterioration level of the consumable part. The degree of deterioration is an index obtained by converting the level of performance of consumable parts into three levels, and is classified into “normal”, “caution”, and “abnormal”. Among these, “abnormal” indicates that the consumable part has reached a level that requires replacement. When the deterioration degree calculation unit 104 calculates the deterioration degree for each consumable part based on the sensor signal, the deterioration degree calculation unit 104 outputs the deterioration degree to the deterioration degree storage unit 106.

  The input unit 120 receives event information regarding replacement work of consumable parts from the user. Event information includes part replacement (removal) and part replacement (attachment).

  The event management unit 110 uses the event information related to the replacement work accepted by the input unit 120 and the event information related to the replacement work for each consumable part based on the degree of deterioration for each consumable part recorded in the deterioration degree storage unit 106 as an event. The data is output to the storage unit 108 and collectively managed.

  The replacement time estimation unit 112 estimates the next replacement time based on history information regarding replacement work for each consumable part recorded in the event storage unit 108.

  The energy saving effect estimation unit 116 saves energy in component replacement based on history information regarding replacement work for each consumable part recorded in the event storage unit 108 and information on the power consumption of the air compressor received from the communication unit 102. Estimate the effect.

  The output display unit 122 outputs and displays information on the next replacement time for each consumable part of the replacement time estimation unit 112 and information on the energy saving effect in the part replacement of the energy saving effect estimation unit 116.

  The display content switching unit 114 displays the information on the next replacement time for each consumable part in the replacement time estimation unit 112 and the information on the information on the energy saving effect in the part replacement of the energy saving effect estimation unit 116, and information on the degree of deterioration for each consumable part. The display is switched based on

  The energy saving contribution DB 118 is a DB that manages the magnitude of energy saving contribution for each consumable part.

  Next, processing contents of the deterioration degree calculation unit 104 will be described. The deterioration degree calculation unit 104 receives the measurement value of the differential pressure sensor 202 attached to the suction filter 5 received from the communication unit 102, the measurement value of the contamination sensor 204 attached to the oil tank 7, and the separator element 8. The degree of deterioration of each consumable part is calculated based on the measured value of the attached differential pressure sensor 206.

  The deterioration degree calculation unit 104 has a sensor threshold value for determining the deterioration degree of each consumable part. Two types of threshold values are held for the measurement value P of the differential pressure sensor 202 attached to the suction filter 5, which is an “attention” determination threshold value Pc and an “abnormal” determination threshold value Pa. The degree-of-degradation calculation unit 104 determines that the measured value P of the differential pressure sensor 202 is “normal” when P <Pc is satisfied, and determines “caution” when Pc ≦ P <Pa is satisfied, and Pa ≦ If P is satisfied, it is judged as “abnormal”. The deterioration degree calculation unit 104 similarly holds two types of threshold values for the contamination sensor 204 for determining deterioration of the lubricating oil 30 and the differential pressure sensor 206 for determining deterioration of the separator element 206, and the suction filter Similar to 5, the degree of deterioration is determined.

  Here, the degradation degree calculation unit 104 assumes analog as various sensor values, but may receive digital 0s and 1s. In that case, 0 and 1 are classified into degradation levels “normal” and “abnormal”, respectively.

  FIG. 3 shows a configuration example of the deterioration degree storage unit 106 that outputs the result of the deterioration degree calculation unit 104 calculating the deterioration degree.

  As shown in FIG. 3, the degradation record storage unit 106 records a measurement record for each consumable part. In the measurement record, the measurement date and time, the accumulated operation time, the measurement sensor value, and the determination result of the deterioration degree are recorded. The measurement date and time is the measurement date and time with a clock included in the monitoring device 100 (not shown) when the sensor data is received. The accumulated operation time is time information calculated by accumulating the operation time measured by the operation time measuring unit 50 in FIG. 2 from the time of shipment, and records the accumulated operation time received via the communication unit 102. The sensor value and the deterioration degree are the calculation results of the deterioration degree calculation unit 104 described above.

  As described above, the deterioration degree calculation unit 104 sequentially calculates the deterioration state of the consumable parts based on the sensor data attached to each consumable part and outputs it to the deterioration degree storage unit 106.

  Next, processing contents of the event management unit 110 will be described with reference to FIGS.

  FIG. 4 is a processing flow of the event management unit 110. In FIG. 4, first, the event management unit 110 reads the content of the deterioration degree storage unit 106 in S2000.

  Next, in step S2100, the event management unit 110 calculates a deterioration degree change for each consumable part. This is a process for searching whether or not the degree of deterioration has changed in the time series change of the degree of deterioration for each consumable part read in S2000. There are two types of changes in the degree of deterioration: a change in the deterioration direction and a change in the improvement direction. The first change in the deterioration direction changes as “normal” → “caution” → “abnormal”, and recognizes that an event “deterioration progress” has occurred when a level change occurs. The second change in the improvement direction is that the degree of deterioration changes from “abnormal” to “normal”, which is a change that appears when parts are replaced. Accordingly, in this case, the event management unit 110 recognizes that an event of “part replacement (removal)” and “part replacement (attachment)” has occurred.

  In step S2200, the event management unit 110 confirms input of event information related to component replacement from the input unit 120. Event information includes part replacement (removal) and part replacement (attachment), which are usually performed at the same timing.

  In S2300, if any event occurs from the processing results of S2100 and S2200 in S2300, event management unit 110 determines YES and proceeds to S2400. If NO, returns to S2000 and performs the processing. repeat.

  The event management unit 110 generates event information and writes the event information in the event storage unit 108 when the determination in S2300 is YES.

  FIG. 5 shows a configuration example of the event storage unit 108. When the event management unit 110 recognizes that an event has occurred, as shown in FIG. 5, the event storage unit 108 stores the date, event information, cycle ID, degree of deterioration, accumulated operation time, Write the cumulative operating time from the replacement and the power consumption.

  The date means the date when the event occurred, and the event management unit 110 recognizes and writes the date from the internal clock of the monitoring apparatus 100.

  The event information means the content of the event whose occurrence is recognized in S2300.

  The cycle ID is an ID for recognizing the replacement cycle of the consumable part. The first part when shipped to the market is set to cycle ID = 1, and thereafter, the ID is incremented by 1 each time the part is replaced. By using this cycle ID and event information, it is possible to compare the period of use and power consumption for the same component.

  The degree of deterioration is the degree of deterioration of the consumable part when an event occurs. The event management unit 110 basically outputs the degradation level read from the degradation level storage unit 106, but when there is no information in the degradation level storage unit 106, the event management unit 110 estimates it in association with the content of the event. Output the degree of deterioration. That is, when the event information = “exchange (removal)”, the degree of deterioration = “abnormal”, and when the event information = “exchange (attachment)”, the degree of deterioration = “normal” is estimated and output. Depending on the consumable parts, the sensor is not necessarily attached, so the event management unit 110 performs such a deterioration degree estimation process in order to deal with a case where event information can be acquired only via the input unit 120. Do.

  The accumulated operation time is information regarding the accumulated operation time received from the operation time measurement unit 50 by the event management unit 110 via the communication unit 102.

  Cumulative operating time from replacement is the cumulative operating time for the same part, the cycle ID is the same, and the event information = “replacement (mounting)” is taken as the standard 0 [hr], indicating the cumulative operating time from that time ing.

  The power consumption means the power consumption received from the power measurement unit 60 by the event management unit 110 via the communication unit 102.

  When the above information is output to the event storage unit 108 in S2400 of FIG. 4, the event management unit 110 returns to S2000 and repeats the process.

  Next, the processing content of the replacement time estimation unit 112 will be described. The replacement time estimation unit 112 determines the next component replacement time for each consumable part based on the information in the event storage unit 108 and the current cumulative operation time information received from the operation time measurement unit 50 via the communication unit 102. presume.

  FIG. 6 is a diagram for explaining replacement time estimation processing in the present embodiment. As illustrated in FIG. 6, the replacement time estimation unit 112 recognizes a deterioration degree change with respect to “cumulative operation time from replacement” for each cycle ID. Thereby, it is possible to calculate the accumulated operation time from the deterioration degree “normal” to “abnormal” for each cycle ID. For devices operating in the same environment, the cumulative operating time until “abnormal” in the past replacement cycle tends to be almost the same, so from “normal” to “abnormal” Can be estimated as an operating time corresponding to the lifetime of the part.

  Then, the replacement time estimation unit 112 calculates the remaining cumulative operating time until the next replacement from the difference between the current cumulative operating time in the cycle ID and the operating time corresponding to the lifetime. Normally, since the air compressor operates for about 8 hours per day, the number of days obtained by dividing the remaining accumulated operation time until the next replacement by 8 hours can be estimated as the number of remaining days until the next replacement. Therefore, it can be estimated that the date obtained by adding the remaining number of days to the current date is the next replacement time.

  Here, the operation time per day is calculated as 8 hours, but the number of days may be strictly calculated based on the information in the event storage unit 108. In addition, since there is no past history for the first cycle ID = 1, the accumulated operating time until the next replacement may be estimated based on the design value of the component life.

  Next, processing contents of the energy saving effect estimation unit 116 will be described. The energy saving effect estimation unit 116 determines that the deterioration level is “normal” for each consumable part based on the information in the event storage unit 108 and the information on the power consumption received from the power measurement unit 60 via the communication unit 102. That is, the power loss rate corresponding to the ratio of the current power consumption to the power consumption when the parts are new is calculated. This power loss rate indicates the magnitude of power loss, and can be estimated as an energy saving effect that can eliminate waste of power consumption by replacing parts.

When the current power consumption w received from the communication unit 102 is PW _now , and the “cumulative operating time from replacement” = 0 in the same cycle ID is PW ₀ , the energy saving effect estimation unit 116 is PW _0. The loss rate Rate _loss is calculated by Equation 1.

  FIG. 7 shows a diagram for explaining the energy saving effect estimation processing in the present embodiment. FIG. 7 shows the power loss rate with respect to “cumulative operation time from replacement” for each cycle ID. Usually, the power loss rate tends to increase as the degree of deterioration of the consumable parts changes from “normal” to “abnormal”. The energy saving effect estimation unit 116 outputs the calculation result of the power loss rate to the display content switching unit 114 and ends the process.

  Next, the processing content of the display content switching unit 114 will be described. The display content switching unit 114 receives, from the event storage unit 108, information on the next replacement time for each consumable part received from the replacement time estimation unit 112 and information on the power loss rate for each consumable part received from the energy saving effect estimation unit 116. Control is performed so as to display on the output display unit 122 while switching according to the degree of deterioration of each read consumable part. That is, the timing for outputting information for prompting replacement of the consumable part and the magnitude of the power loss is changed according to the deterioration state of the consumable part.

  FIG. 8 is a diagram illustrating an example of a display screen in the output display unit 122. Three representative icons indicating the degree of deterioration “normal”, “caution”, and “abnormal” are prepared on the output display unit 122, and are lit and displayed according to the current state of the consumable parts. Then, detailed information is presented at the bottom.

  FIG. 8A is an example of a display when the deterioration levels of all consumable parts are “normal”. The icon indicating “normal” on the left side is lit. In the lower part, detailed information “normally operating” is shown.

  FIG. 8B is an example of a display when the degree of deterioration of any consumable part has reached “Caution”. In this case, the icon indicating “caution” in the center is turned on. In the lower part, information indicating that “part replacement time is approaching” is presented, and the names of consumable parts that have actually reached the level of “caution” are displayed. In this example, the case of lubricating oil is shown. And the information regarding the next replacement time of the said consumable part received from the replacement time estimation part 112 is displayed as detailed information.

  FIG. 8 (3) is an example of a display when the deterioration degree of any consumable part reaches “abnormal”. In this case, the icon indicating “abnormal” on the right side is turned on. In the lower part, the name of the consumable part whose deterioration degree has reached “abnormal” is displayed together with a comment such as “Power is consumed wastefully?”. Here, a numerical value related to the power loss rate of the consumable part received from the energy saving effect estimation unit 116 is output to the “???%” portion of the display content. As a result, if parts are not replaced, useless power is consumed, and it is possible to tell that the user is losing money. It is also possible to tell that the replacement of parts can eliminate this power loss and realize energy saving.

  Here, the display content switching unit 114 lists and displays a plurality of consumable parts when a plurality of consumable parts have reached the degree of deterioration “caution” in the display of FIG. In this case, the display switching unit 114 refers to the energy saving contribution DB 118 to display the consumable parts having the largest power contribution rate in order.

  FIG. 9 shows a configuration example of the energy saving contribution DB 118. As shown in FIG. 9, the energy saving contribution DB 118 indicates the power contribution rate for each consumable part. This power contribution rate is power contribution information indicating the magnitude of contribution to power loss in a plurality of consumable parts, and is power loss contribution information indicating the magnitude of contribution to power loss. It shows that the energy saving effect by parts replacement is larger as the contribution ratio is larger.

  In addition, when the plurality of consumable parts have reached the deterioration level “abnormal” in the display of FIG. 8C, the display content switching unit 114 selects the plurality of consumable parts that need to be replaced in descending order of power contribution ratio. As for the power loss rate of “???%”, the power loss rate of the consumable component having the maximum power contribution ratio among the consumable components that have reached the deterioration level “abnormal” is displayed. Thereby, the display content switching unit 114 can present information related to effective component replacement to the user by changing the content displayed on the output display unit 122 according to the degree of deterioration of the consumable component. it can.

  Instead of the power loss rate shown in FIG. 8, an electricity rate, a reduced amount of compressed air when the monitoring target is an air compressor, or other indicators related to the air compressor may be used.

  As described above, this embodiment is a monitoring method of a monitoring device that outputs information that prompts replacement of consumable parts based on the deterioration state of the consumable parts of the device, and outputs the magnitude of power loss with respect to a certain time base point. To be configured.
