Description

The present invention relates to a test equipment management system and a management device for managing the state of environmental test equipment.

Conventionally, as described in Patent Documents 1 to 3 below, the operating status of maintenance target equipment such as working machines and industrial equipment is transmitted to a server, and the server receives the received operating status and the same type of maintenance target equipment. A technology is known that predicts when an abnormality will occur based on the operating status obtained from the device and notifies the user of the abnormality before it occurs.

However, if the equipment subject to maintenance is in a state just before becoming abnormal, even if the equipment subject to maintenance is operated under operating conditions with a small burden, the operating status of the equipment subject to maintenance will be normal under operating conditions with a heavy burden. It may be almost the same situation as when it is running on In this case, in the conventional techniques described in Patent Documents 1 to 3, etc., the operating status transmitted by the maintenance target device is the operating status when the same type of device as the maintenance target device is operating normally under operating conditions with a heavy burden. Since the situation is almost the same, there is a possibility that it may be erroneously predicted that an abnormality will not occur soon.

In this case, there is a risk that the user, who has been notified of the erroneously predicted abnormality occurrence time, may decide that the abnormality occurrence time is not near and continue the operation of the maintenance target device. As a result, the maintenance target device becomes abnormal, and there is a possibility that the maintenance target device cannot be used until the maintenance target device is repaired so that it can operate normally.

Contrary to the above, when the equipment subject to maintenance is operating normally under operating conditions that impose a heavy load, the equipment subject to maintenance that is in an abnormal state is operating under operating conditions that impose a light burden. It can be almost the same situation. In this case, in the conventional techniques described in Patent Documents 1 to 3, etc., the operating status transmitted by the maintenance target device is that the same type of device as the maintenance target device in an abnormal state is operating under operating conditions with a small burden. Since the operation status is almost the same as the operating status at that time, there is a risk of erroneously determining that an abnormality has already occurred. In this case, the user who received the determination result of the occurrence of the abnormality may forcibly stop the operation of the maintenance target device even though the maintenance target device is operating normally.

After the execution unit 21 causes the display unit 24 to display an operation screen for setting test conditions, as shown in FIG. S11), the test of the sample is started (S12). Specifically, in S12, the execution unit 21 controls the environment adjuster 27 to adjust the ambient environment of the sample according to the test conditions set in S11.

When the test is started, the transmission unit 22 controls the interface unit 23 so that the identification information of the environmental test apparatus 2 (hereafter referred to as the apparatus ID) and the surroundings of the sample included in the test conditions set in S11. A process of periodically transmitting the target value of the environment, the detection value of the environment sensor 28, the detection value of the state sensor 29, and the test information such as the adjustment period to the management device 1 is started (S13). As a result, the test information is periodically transmitted to the management device 1 while the environment adjuster 27 is adjusting the test (during adjustment).

Then, it is assumed that the interface unit 23 receives warning information or warning information, which will be described later, notified from the management device 1, and outputs the received information to the control unit 20 (S14; YES). In this case, the execution unit 21 causes the display unit 24 to display the received information (S15).

If the information received in S14 is not alarm information (S16; NO) and all adjustment periods included in the test conditions have not passed (S17; NO), the execution unit 21 returns the process to S14. . After that, the processing after S14 is performed. On the other hand, if the information received in S14 is warning information (S16; YES) and if all the adjustment periods included in the test conditions have passed (S17; YES), the executing section 21 ends the test.

(Operation flow of state management of the environmental test apparatus 2)
The operation of managing the state of the environmental test device 2 in the management device 1 will be described below. FIG. 8 is a flow chart showing the state management operation of the environmental test device 2 in the management device 1 . In the description, details of the reception unit 101, the determination unit 102, the notification unit 103, and the prediction unit 104 will be described.

As shown in FIG. 8, when the communication unit 11 receives each test information transmitted by the environmental test apparatus 2 during adjustment and outputs each received test information to the control unit 10 (S21), the reception unit 101 , stores the received test information in the storage unit 14 (S22).

FIG. 9 is a diagram showing an example of test information stored in the storage unit 14. As shown in FIG. For example, as shown in FIG. 9, in S22, the storage unit 14 stores the test information received in S21 under the control of the reception unit 101 in association with the reception time of the test information. FIG. 9 shows an example in which the storage unit 14 stores n pieces of test information received from the environmental test device 2 identified by the device ID "M1" during times t11 to t1n. In FIG. 9, after times t11 to t1n, the storage unit 14 stores n pieces of test information received from the environmental test device 2 identified by the device ID "M2" at times t21 to t2m and t2m+1 to t2n. After that, n pieces of test information received from the environmental test device 2 identified by the device ID “M3” during times t31 to t3n are stored.

For example, the test information received at time "t11" from the environmental test apparatus 2 identified by the apparatus ID "M1" stored in the storage unit 14 includes the apparatus ID "M1" of the environmental test apparatus 2 that transmitted the test information. "It is included. The test information includes a target temperature "T1", a target humidity "H1", and an adjustment period "D1" as test conditions. The test information includes the temperature "Ta11" and humidity "Ha11" of the test area as detection values (hereinafter referred to as environment detection values) of the environment sensor 28 (FIG. 2).

In addition, the test information includes temperature "Tb11" and humidity "Hb11" in the electrical equipment room as detection values (hereinafter referred to as "state detection values") of the state sensor 29 (FIG. 2), It includes temperature "Tc11" and pressure "Sc11", voltage "Vc11" and current "Ic11" applied to a compressor (not shown) of the refrigerator, vibration "Bc11" of the refrigerator, and the like.

In addition, the test information includes, as state detection values, the ambient temperature "Td11" and humidity "Hd11" outside the machine room in which the refrigerator is installed, the voltage "Vd11" and the current "Id11" supplied to the refrigerator. ", the water temperature "Wd11" and flow rate "Fd11" of the cooling water supplied to and discharged from the refrigerator, and the temperature (exhaust temperature) "Gd11" of the exhaust air discharged from the refrigerator. .

Refer back to FIG. After S22, the determination unit 102 determines the environmental test apparatus 2 ( Thereafter, a process (second determination process) for determining whether or not the target environmental test apparatus is in a normal state is performed (S23). The target test information indicates test information including test conditions of the same type as the reception test information, which is stored in the storage unit 14 before the ambient environment of the sample in the target environment test apparatus is adjusted. The test conditions of the same kind as the reception test information indicate test conditions that include all the test conditions included in the reception test information.

That is, according to S23, the target environmental test device performed in each of the one or more environmental test devices 2 is not one or more states of the environmental regulator under adjustment according to test conditions different from the target environmental test device. Based on one or more states of the environmental conditioner being adjusted according to test conditions of the same type as the above, it is possible to appropriately determine whether the target environmental test device is in a normal state.

FIG. 10 is an explanatory diagram of an example of processing for determining whether the target environmental test apparatus is in a normal state. Specifically, in S23, the determination unit 102 selects k representative values p (=(p1, p2, , pk)) are calculated.

As the k types of representative value p, for example, an average value of k types of state detection values included in the target test information may be adopted, or an upper limit value or a lower limit value may be adopted. , the median may be taken. In addition, each of the k types of representative values p may have a width. That is, predetermined statistical processing is performed on each of the k types of state detection values included in the target test information, and all state detection values included in the range determined by the statistical processing are converted into k types of representative values. may be employed as each of p. Not limited to these, the state detection values selected and operated by the user using the operation unit 13 from among the k types of state detection values included in the target test information are adopted as the k types of representative values p. may

Then, as shown in the solid line part in FIG. The Euclidean distance ED (=((q1-p1) ² +(q2-p2) ² +...+(qk-pk) ² ) to the 1/2 power) between the representative value p of If the above is the case, it is determined that the target environmental test device is not in a normal state.

For example, it is assumed that the storage unit 14 stores test information associated with reception times t11 to t3n as shown in FIG. After time t3n, it is assumed that the received test information received from the target environmental test apparatus identified by the apparatus ID "M4" includes target temperature "T1" and target humidity "H1" as test conditions. It is assumed that the k kinds of state detection values are two kinds of state detection values of the refrigerator voltage and current. Also, the k (k=2) types of representative values are assumed to be the average values of the state detection values of the voltage and current of the refrigerator included in the target test information.

In this case, in S23, the determination unit 102 determines the reception times t11 to t1n, t21 to t2m, t31 to t3n including the target temperature "T1" and the target humidity "H1" which are the test conditions included in the reception test information. 2n+m pieces of test information associated with (FIG. 9) are set as target test information.

Then, the determination unit 102 calculates the average value of the two types of state detection values of the voltage and current of the refrigerator included in the target test information, and divides the calculated average value into the two types of representative values p (=(p1, p2), p1=(Vc11+...+Vc1n+Vc21+...+Vc2m+Vc31+...+Vc3n)/(2n+m), p2=(Ic11+...+Ic1n+Ic21+...+Ic2m+Ic31+...+Ic3n)/(2n+m )).

Then, the determination unit 102 determines the Euclidean distance between the two state detection values q1 and q2 of the voltage and current of the refrigerator included in the reception test information and the two representative values p1 and p2 calculated above. When ED (=((q1-p1) ² +(q2-p2) ² ) to the power of 1/2) is equal to or greater than a predetermined length L, it is determined that the target environmental test apparatus is not in a normal state.

According to this configuration, even if the test information includes detection values of a plurality of types of states of the environment adjuster 27, the target environmental test device performed in each of the one or more environmental test devices 2 Calculate the Euclidean distance ED from the detected values of multiple types of states of the environmental regulator 27 under adjustment according to the test conditions of the same type, and whether the target environmental test device is in a normal state based on the calculated Euclidean distance ED It is possible to appropriately determine whether or not

In S23, the determination unit 102 determines whether the target environmental test device is in a normal state based on the state detection values included in the reception test information and the target test information, using a method different from the above. may be determined.

For example, the determination unit 102 determines a vector x (vector (x11, ..., x1m), ..., vector (xk1, ..., xkm))) and the m objects sequentially received from the start of the test until the predetermined time elapses The following expression using the vector u (= u1, ..., um) representing the set of average values (representative values of k types) uk of k types of state detection values included in the test information If the Mahalanobis distance MD(x) represented by (1) is equal to or greater than a predetermined length L, it may be determined that the target environmental test apparatus is not in a normal state.

In this case, even if the test information includes detection values of multiple types of states of the environmental regulator 27, the same kind of target environmental test device as the target environmental test device performed in each of the one or more environmental test devices 2 A Mahalanobis distance MD(x) is calculated from detected values of a plurality of types of states of the environment adjuster 27 being adjusted according to the test conditions, and the target environmental test device is in a normal state based on the calculated Mahalanobis distance MD(x). It can be appropriately determined whether or not.

Refer back to FIG. Assume that the determination unit 102 determines in S23 that the target environmental test apparatus is not in a normal state (S23; NO). In this case, the determination unit 102 determines whether or not the target environmental test apparatus is in a warning state immediately before becoming abnormal based on the environment detection values included in the received test information and the target test information. Processing (first determination processing) is performed (S24).

In other words, in S24, the ambient environment of the sample being adjusted according to the predetermined test conditions in the target environmental test device indicated by the reception test information and the target environmental test in each of the one or more environmental test devices 2 indicated by the target test information A determination is made as to whether the subject environmental test device is in a warning state based on the device and the ambient environment of the specimen when it was previously conditioned according to the same type of test conditions.

For this reason, the surrounding environment of the sample being adjusted according to the predetermined test conditions in the target environmental test equipment and the one or more environmental test equipment 2 were each adjusted in the past according to test conditions different from those of the target environmental test equipment. Rather than determining whether the target environmental test device is in a warning state based on the ambient environment of the sample at the time of It is possible to appropriately determine whether or not there is

FIG. 11 is an explanatory diagram of an example of processing for determining whether or not the target environmental test apparatus is in a warning state. Specifically, in S24, the determination unit 102 changes the environment detection value included in the reception test information from the first value d1 to the second value d2, as indicated by the dashed line and the two-dot chain line in FIG. The time required for the change and the time required for the environmental detection value included in the target test information to change from the first value d1 to the second value d2 as indicated by the solid line in FIG. When the time difference DT between the first representative value of and is greater than or equal to a predetermined first reference time, it is determined that the target environmental test apparatus is in the warning state.

As the first representative value, the time required for one or more environmental detection values during each adjustment, included in the target test information, to change from the first value d1 to the second value d2 (hereinafter referred to as the required time ) may be adopted, the upper limit value or the lower limit value may be adopted, or the median value may be adopted. Also, as indicated by the bold arrow in FIG. 11, the first representative value may have a range. Further, predetermined statistical processing is performed on the required time required for one or more environmental detection values during each adjustment to change from the first value d1 to the second value d2, which is included in the target test information, and the statistical All required times included in the range determined by the process may be adopted as the first representative value. Not limited to these, from the time required for one or more environment detection values during each adjustment to change from the first value d1 to the second value d2 included in the target test information, the user operates the operation unit 13 may be employed as the first representative value.

For example, it is assumed that the storage unit 14 stores test information associated with reception times t11 to t3n as shown in FIG. Further, after the time t3n, the received test information received from the target environment test device identified by the device ID "M5" during the time t51 to t5n contains two combinations of target temperature and target humidity as test conditions. Assume that "T1, H1" and "T2, H2" are included. It is also assumed that the environment detection value used for the determination in S24 is the temperature detection value of the test area.

In this case, in S24, the determining unit 102 determines, in the same way as the test conditions included in the reception test information, the reception conditions including two sets of combinations "T1, H1" and "T2, H2" of the target temperature and the target humidity. The n pieces of test information associated with times t21 to t2n (FIG. 9) are assumed to be target test information. Further, the determination unit 102 sets the two target temperatures "T1, T2" included in the reception test information and the target test information to a first value d1 (=T1) and a second value d2 used for the determination in S24, respectively. (=T2).

Further, in this specific example, the target test information including the test conditions of the same type as the reception test information includes: Only test information sent during one adjustment is included. For this reason, the determination unit 102 determines that the detected temperature values “Ta21, . . . , Ta2m, Ta2m+1, . =T1) to the second value d2 (=T2) is defined as the predetermined first representative value.

It should be noted that unlike this specific example, the target test information including the test conditions of the same type as the reception test information includes test information transmitted during a plurality of adjustments performed in a plurality of environmental test apparatuses 2, respectively. Suppose that In this case, as described above, the determination unit 102 determines the time required for the detected value of the temperature of the test area included in the test information transmitted during each adjustment to change from the first value to the second value. may be used as the first representative value.

Then, as in FIG. 11, the determining unit 102 generates a graph with the test information reception time on the horizontal axis and the temperature detection value of the test area included in the test information on the vertical axis. Calculate the time required for the detected temperature value of the test area included in to change from the first value d1 (=T1) to the second value d2 (=T2). Then, when the time difference DT between the calculated time and the first representative value is equal to or greater than a predetermined first reference time, the determination unit 102 determines that the target environmental test device is in the warning state.

According to this configuration, the detection value of the ambient environment of the sample being adjusted indicated by the received test information and the test conditions of the same type as the adjustment performed in the past in one or more environmental test apparatuses 2 indicated by the target test information are used. Based on the time difference between the detected value of the ambient environment of the sample being adjusted and the time required to change from the first value d1 to the second value d2, it is appropriately determined whether the target environmental test device is in a warning state. can be determined.

In S24, the determination unit 102 uses a method different from that described above to determine whether the target environment test device is in an abnormal state based on the environment detection values included in the reception test information and the target test information. You may make it determine whether it is in a warning state.

Refer back to FIG. Assume that the determination unit 102 determines in S24 that the target environmental test apparatus is in a warning state (S24; YES). In this case, the determination unit 102 determines whether or not the target environmental test device is in an abnormal state based on the state detection values included in the reception test information and the target test information (third determination processing). (S25).

That is, in S25, the target environmental test device is abnormal based on one or more states of the environmental regulator 27 being adjusted according to the test conditions of the same type as the target environmental test device performed in each of the one or more environmental test devices 2. It is possible to appropriately determine whether or not the state is

FIG. 12 is an explanatory diagram of an example of processing for determining whether or not the target environmental test apparatus is in an abnormal state. Specifically, in S25, the determination unit 102 determines that any one state detection value included in the reception test information is the one state detection value included in the target test information, as indicated by the solid line in FIG. If the detected state value d0 exceeds the predetermined second representative value d0 continuously for a predetermined time ET or longer, it is determined that the target environmental test apparatus is in an abnormal state.

As the second representative value d0, an average value of the one state detection values included in the target test information may be adopted, an upper limit value or a lower limit value may be adopted, or a median value may be adopted. may be Not limited to these, a state detection value selected and operated by the user using the operation unit 13 from among the one state detection values included in the target test information may be adopted as the second representative value d0. .

It should be noted that, as indicated by the solid line in FIG. It indicates that the time ET or more has exceeded continuously. However, not limited to this, for example, when both the one state detection value and the second representative value d0 indicate negative values, depending on the values indicated by the one state detection value and the second representative value d0, one state detection When the value is continuously below the second representative value d0 for the predetermined time ET or more, the determination unit 102 determines that the one state detection value continuously exceeds the second representative value d0 for the predetermined time ET or more. You may make it

For example, it is assumed that the storage unit 14 stores test information associated with reception times t11 to t3n as shown in FIG. After time t3n, the received test information received from the target environmental test device identified by the device ID "M6" from time t61 to time t6n includes two combinations of target temperature and target humidity as test conditions. Assume that "T1, H1" and "T2, H2" are included.

In this case, in S25, the determining unit 102 determines, in the same manner as the test conditions included in the reception test information, the reception conditions including two sets of combinations of target temperature and target humidity, "T1, H1" and "T2, H2." The n pieces of test information associated with times t21 to t2n (FIG. 9) are assumed to be target test information. Further, the determining unit 102 sets the detection value "Vc21, ..., Vc2n" of the voltage of the refrigerator included in the target test information as the one state detection value, The average value of the detected values of the machine voltage is calculated as the second representative value d0 (=(Vc21+...+Vc2n)/n).

Then, if the detected value of the voltage of the refrigerator included in the reception test information continuously exceeds the second representative value d0 for the predetermined time ET or longer, the determination unit 102 determines that the target environmental test apparatus is in an abnormal state. It is determined that Similarly, the determination unit 102 determines that the detection value of the vibration of the refrigerator among the state detection values included in the reception test information is the detection value of the vibration of the refrigerator included in the target test information "Bc21,. . . , Bc2n”, which is the average value of the second representative value d0 (=(Bc21+...+Bc2n)/n), is continuously exceeded for a predetermined time ET or more. state.

According to this configuration, even if the test information includes only the detection value of one of the one or more states of the environment adjuster 27, the Appropriately determine whether or not the target environmental test device is in an abnormal state by using the detected value of the one type of state of the environmental regulator 27 under adjustment according to the test conditions of the same type as the target environmental test device. can be done.

In S25, the determination unit 102 determines whether the target environmental test device is in an abnormal state based on the state detection values included in the receiving test information and the target test information by a method different from the above. may be determined.

For example, in S25, the determination unit 102 determines that any one of the state detection values included in the reception test information is one of the states included in the target test information, as indicated by the dashed line in FIG. It may be determined that the target environmental test apparatus is in an abnormal state when the detected value exceeds a predetermined second representative value d0 more than a predetermined number of times during the predetermined time ET. Note that FIG. 12 shows an example in which any one of the detected state values exceeds the second representative value d0 three times.

Refer back to FIG. Assume that the determination unit 102 determines in S25 that the target environmental test apparatus is in an abnormal state (S25; YES). In this case, the notification unit 103 (FIG. 6) notifies the target environmental test device of an alarm indicating that the target environmental test device is in an abnormal state (S26). Specifically, in S26, the notification unit 103 (FIG. 6) controls the communication unit 11 to send alarm information indicating that the target environmental test apparatus is in an abnormal state to the target environment test apparatus via the network 9. Have the device send. In S26, the notification unit 103 (FIG. 6) may transmit the alarm information to a personal computer or the like for monitoring the target environmental test apparatus via the network 9. FIG.

Therefore, the user of the target environmental test device who has received the notification can quickly finish the adjustment in the target environmental test device. As a result, it is possible to avoid unnecessary continuation of abnormal adjustments in the target environment test apparatus in an abnormal state.

On the other hand, if it is determined in S23 that the target environmental test device is in a normal state (S23; YES), and if it is determined in S24 that the target environmental test device is not in a warning state (S24; NO), prediction The unit 104 performs processing (prediction processing) for predicting the life expectancy until the environmental regulator 27 of the target environmental test device reaches the end of its life based on the state detection values included in the receiving test information and the target test information. (S29).

FIG. 13 is an explanatory diagram of an example of a process in which the prediction unit 104 predicts the life expectancy LE. Specifically, as shown in FIG. 13, in S29, the prediction unit 104 successively detects any one of the predetermined state detection values included in the reception test information. It is plotted on two-dimensional coordinates with the time as the time and the vertical axis as the one state detection value. Then, the prediction unit 104 performs predetermined known regression analysis processing to calculate a function (curve indicated by a dashed line) representing the relationship between the one state detection value and time. Then, using the calculated function, the prediction unit 104 calculates the time te at which the one state detection value becomes the abnormal value de. The prediction unit 104 predicts the calculated time te as the time when the environmental regulator 27 of the target environmental test apparatus reaches the end of its life.

The abnormal value de indicates, for example, a value obtained by multiplying the upper limit value (or lower limit value) of the one state detection value included in the target test information by a predetermined value. However, the abnormal value de is not limited to this, and the value input by the user using the operation unit 13 to the upper limit value (or lower limit value) of the one state detection value included in the target test information. An added (or subtracted) value or the like may be used.

Then, the prediction unit 104 calculates the life expectancy from the time tc at which the test information is received at the end of the adjustment in the target environmental test device to the time te at which the predicted environmental adjuster 27 of the target environmental test device reaches the end of its life. Forecast as period LE.

Refer back to FIG. After S29, the notification unit 103 (FIG. 6) notifies the target environmental test apparatus of the life expectancy LE predicted in S29 (S30). Specifically, in S<b>30 , the notification unit 103 controls the communication unit 11 to transmit information indicating the life expectancy LE to the target environmental test device or the like via the network 9 .

That is, if it is determined in S23 that the target environmental test device is in a normal state (S23; YES), and if it is determined in S24 that the target environmental test device is not in a warning state (S24; NO), S29 , the life expectancy is appropriately predicted based on one or more states of the environmental regulator 27 being adjusted according to the test conditions of the same type as the target environmental test device performed in each of the one or more environmental test devices 2 ( S29). Then, in S30, the predicted life expectancy is notified (S30).

Therefore, the user of the target environmental test apparatus who has received the notification can appropriately grasp the period required for the environmental adjuster 27 to reach the end of its life before the warning state occurs. This allows the user to check the target environmental test device, for example, to reduce the risk of the target environmental test device becoming abnormal, with time to spare.

Further, when it is determined in S25 that the target environmental test apparatus is not in an abnormal state (S25; NO), the prediction unit 104 performs a process of predicting the life expectancy LE as in S29 (S27). After S27, the notification unit 103 (FIG. 6) notifies the target environmental test device of the life expectancy LE predicted in S27 and a warning indicating that the target environmental test device is in a warning state (S28). Specifically, in S28, the notification unit 103 controls the communication unit 11 to transmit the information indicating the life expectancy LE and the warning information indicating that the target environmental test apparatus is in a warning state via the network 9. Send to the environmental test equipment.

For this reason, the user of the target environmental test equipment who has received these notifications must set the period required for the environmental regulator 27 of the target environmental test equipment to reach the end of its life while the target environmental test equipment is in the warning state. can be properly grasped. As a result, the user can quickly perform work to reduce the possibility that the target environmental test device will become abnormal, such as inspecting the target environmental test device.
