The specific embodiment
Fig. 1 means the integral structure example of present embodiment.
Liquid Crystal Display 1 (example of display equipment) is the equipment as the life-span management object, is the example of management object equipment.And, be also that the more example of the efferent of the message of switching liquid crystal display 1 (life-span expiration notice message) is urged in the output of narrating later.
Liquid Crystal Display 1 for example is configured in the car 100 of elevator as shown in Figure 2.And Liquid Crystal Display 1 for example is configured in elevator floor stops 200 as shown in Figure 3.
Liquid crystal control and actuating device 2 (display control unit of elevator) according to elevator controling information 8, send power supply and control signal 7, carry out thus the switching of video of the power connection of Liquid Crystal Display 1 and cut-out, demonstration and/or the adjusting of picture.
And, in liquid crystal control and actuating device 2, power monitoring section 14 monitors by the situation of the power connection to Liquid Crystal Display 1 that liquid crystal is controlled and actuating device 2 carries out, and to the time instrumentation section 3 be provided for notifying the energising historical information 9 of the current"on"time that Liquid Crystal Display 1 switches on.
Time, instrumentation section 3 had the lifetime counter of the Liquid Crystal Display 1 that comprises timing piece etc., according to energising historical information 9, lifetime counter was changed.That is, the time instrumentation section 3 according to the current"on"time by energising historical information 9 notices, derive the life-span count value (aging evaluation number) of the degree of aging of symbol Liquid Crystal Display 1, make the value of lifetime counter increase the amount of the life-span count value derived.Time, instrumentation section 3 was examples of aging evaluation section.
Judging service life section 6 regularly compares the integral age count information 12 recorded by recording unit 5 and the lifetime data that Liquid Crystal Display 1 is set, in the situation that the former value approaches the latter's value very much, judgement is the replacing period of Liquid Crystal Display 1.In addition, lifetime data refers to the information that expires count value life-span in life-span when the life-span expires count value (life-span expire aging evaluation number) means.The value (aggregate-value) of the lifetime counter that judging service life section 6 means integral age count information 12 and the life-span count value that expires compares, and whether the life-span of judgement Liquid Crystal Display 1 soon expires, and determines whether it is the replacing period of Liquid Crystal Display 1.
Liquid crystal is controlled and the control part 15 of actuating device 2 is switched on to Liquid Crystal Display 1 in common elevator work, at night or during the park mode that temporarily can not utilize or at elevator when stopping utilizing state, controlled according to elevator controling information 8, made the power supply of cutting-off liquid crystal display 1.
And, in the situation that be judged to be Liquid Crystal Display 1 is switched on by power monitoring section 14, offer time instrumentation section 3 using T second actual current"on"time as energising historical information 9.
In this case, the time, instrumentation section 3 was made as T second to the life-span count value, made the counting of lifetime counter increase T second.
In addition, when in the situation that night or park mode time control be made for reduce Liquid Crystal Display 1 brightness (, in situation with the energising of the current value lower than standard current value), from power monitoring section 14 to the time instrumentation section 3 energising historical information 9 is provided, it is that T second and Liquid Crystal Display 1 are reducing under the pattern of brightness and work that this energising historical information 9 is notified current"on"time.In the situation that brightness is lower, flow to the current value of cold-cathode tube lower than common state, impact on the life-span is smaller, thus the time instrumentation section 3 as the life-span count value, for example make, the T1 second shorter than T second current"on"time (T1=T/2 second) counting of lifetime counter increase T1 second.
In addition, when in the situation that carried out the on/off of power supply in the extremely short time, will bring considerable influence to the aging speed of cold-cathode tube.In this case, from power monitoring section 14 to the time instrumentation section 3 energising historical information 9 is provided, this energising historical information 9 notices are T second and the situation of repeatedly having carried out at short notice power connection/disconnection current"on"time, time, instrumentation section 3 as the life-span count value, for example made, the T2 second longer than T second current"on"time (T2=2 * T second) lifetime counter increase T2 second.
In addition, in the cut situation of power supply, energising historical information 9 is 0 second, and lifetime counter is constant.
In addition, energising historical information 9 is provided with the energising condition notification sign of the energising situation of notice Liquid Crystal Display 1, so that notice Liquid Crystal Display 1 is reducing the situation of working under the pattern of brightness or the situation of repeatedly carrying out at short notice power connection/disconnection.
And, the value of the time instrumentation section 3 energising condition notification signs according to energising historical information 9, the energising situation of judgement Liquid Crystal Display 1.
And, about the output opportunity of energising historical information 9, can be when Liquid Crystal Display 1 be switched on, on the opportunity of the end of the power connection to Liquid Crystal Display 1, export the energising historical information 9 of the current"on"time for notifying this power connection of 1 time, also (for example 30 minutes) at regular intervals, output is for gathering the energising historical information 9 of the current"on"time more than 0 time in the notice certain hour.
Below, according to time instrumentation section 3 the action example of the flowchart text present embodiment of Fig. 4.
At first, instrumentation section 3 determined whether and inputted energising historical information 9 from power monitoring section 14 time, if input (S101: be), judge whether energising historical information 9 means that Liquid Crystal Display 1 works (state of a half intensity) (S102) under the pattern that reduces brightness, in the situation that energising historical information 9 means the state (S102: be) of a half intensity, the life-span count value is made as to T1 second, makes the counting of lifetime counter increase T1 second (S105).
And, in the situation that energising historical information 9 does not mean the state (S102: no) of a half intensity, judge whether energising historical information 9 means repeatedly to have carried out at short notice power connection/disconnection (S103), when energising historical information 9 means repeatedly to carry out at short notice in the situation of power connection/disconnection (S103: be), the life-span count value is made as to T2 second, makes the counting of lifetime counter increase T2 second (S106).
On the other hand, when energising historical information 9 is not shown in (S103: no) in the situation of repeatedly carrying out power connection/disconnection in the short time, the life-span count value is made as to T second, makes the counting of lifetime counter increase T second (S104).
And, time, instrumentation section 3 for example, in when lifetime counter changes or at regular intervals (every 1 hour), mean the life-span count information 13 of the value of lifetime counter to recording unit 5 outputs, make recording unit 5 record life-span count information 13 (S107).
In addition, in the situation that energising historical information 9 has meaned the relevant repeatedly current"on"time of energising, carry out the processing of step S102～S106 for each current"on"time, obtain for life-span count value T～T2 of each current"on"time of current"on"time repeatedly, and the counting of lifetime counter is increased.
And, after time instrumentation section 3 processing at step S107 finish, make the value of lifetime counter revert to initial value, in order to the historical information of input energising next time.
And recording unit 5, whenever new input life-span count information the time, by recorded life-span count information and count value addition in the past, and is recorded in inside as integral age count information 12 (unit for hour).
And, the easy expressivity memory device of these recording unit 5 right and wrong etc., liquid crystal control and the cut situation of power supply of actuating device 2 self under, integral age count information 12 can not disappear yet.
The life-span of the standard that judging service life section 6 record is set Liquid Crystal Display 1 count value (for example 70 that expires, 000 hour) lifetime data that means, and obtain termly the integral age count information 12 of recording unit 5 records, the lifetime data of Liquid Crystal Display 1 and integral age count information 12 are compared.
Wherein, the life-span that approaches very much the lifetime data of Liquid Crystal Display 1 in the value of integral age count information 12 count value (for example 69 that expires, 500 hours) situation under, the life-span that is judged to be Liquid Crystal Display 1 approaches the time limit, be that the replacing of Liquid Crystal Display 1 is arrived period, and the life-span that generates Liquid Crystal Display approach the time limit, urge the more message of switching liquid crystal display 1 (life-span expiration notice message), and make Liquid Crystal Display 1 show this message.
Below, according to the action example of the flowchart text judging service life section 6 of Fig. 5.
Judging service life section 6 regularly obtains integral age count information 12, the value of the value of the lifetime data of Liquid Crystal Display 1 and integral age count information 12 is compared to (S201) simultaneously.
Then, the value that integral age count informations 12 are judged by judging service life section 6 whether 500 hours of lifetime data with interior (S202), when not in 500 hours (S202: no), end process.
When in 500 hours (S202: be), judging service life section expiration notice message 6 generation lifetime (S203), and life-span expiration notice message is exported to Liquid Crystal Display 1 (S204), make Liquid Crystal Display 1 display life expiration notice message.
In addition, 500 hours shown in Fig. 5 are example just, and the output reference of life-span expiration notice message is not limited to 500 hours.
At present, about the life-span of Liquid Crystal Display, in the situation that be judged to be on picture the appearance point defect or the localities such as line defect, flicker are bad is judged, except from setting through the New Year number, do not consider current"on"time.About in the situation that in fact find the bad mode of being changed of locality on picture, unless produced badly, otherwise can not change, the efficiency of maintenance is also poor.
In addition, due to service personnel likely leak see bad, so likely cause bad be placed no matter.
If employing native system, can be according to specifically learning current"on"time according to every elevator or each elevator floor stops and the replacing period of different Liquid Crystal Displays, do not grasp replacing period so do not need to spend the time, and by notice replacing period, can prevent because not changed cause bad, and improve maintenance efficiency.
That is,, by judging the life-span and showing and urge the message of changing, can prevent from missing replacing opportunity on the picture of Liquid Crystal Display, because placing no matter under the not bright light caused, the Visual Confirmation that causes because of bad point, degradation is bad.
In addition, due to saved record that year number is set and picture confirm (confirmation has or not point defect, line defect etc.) these grasp the replacing thing in period, so can expect the raising of maintenance efficiency.
In addition, narrated in the above description such example, time instrumentation section 3 contents according to energising historical information 9, if the state of a half intensity, the life-span count value is judged to be to T1 second, if repeatedly carried out at short notice power connection/disconnection, the life-span count value is judged to be to T2 second, if common energising situation is judged to be T second by the life-span count value.
Unlike this, for example, if the state of a half intensity, power monitoring section 14 generates the energising historical information 9 of being notified second being made as T1 current"on"time, and export to time instrumentation section 3, if repeatedly carry out at short notice power connection/disconnection, power monitoring section 14 generates the energising historical information 9 of being notified second being made as T2 current"on"time, and export to time instrumentation section 3, if common energising situation, power monitoring section 14 generates the energising historical information 9 of being notified second being made as T current"on"time, and export to time instrumentation section 3, instrumentation section 3 current"on"times of meaning according to energising historical information 9 time, the lifetime counter counting is increased.
In this case, aging evaluation number is derived by power monitoring section 14, and power monitoring section 14 is examples of aging evaluation section.
Above, the liquid crystal of explanation is controlled and actuating device in the present embodiment, to carry out in the car of elevator and the control of the Liquid Crystal Display that stop arranges and liquid crystal control and the actuating device of driving, be primarily characterized in that, have: timing piece equal time instrumentation section, its life-span to Liquid Crystal Display is counted; The recording units such as nonvolatile memory, the value of its lifetime counter that instrumentation arrives for recording; Power monitoring section, it is energising and the supply disconnecton information to Liquid Crystal Display to described time instrumentation section transmission; And judging service life section, it will compare from the value of the lifetime counter of described recording unit and the standard life-span that Liquid Crystal Display is set, and judge the life-span.
In addition, following situation has been described in the present embodiment, described time, instrumentation section was in the situation that switched on to Liquid Crystal Display, the counting of lifetime counter is increased, in the cut situation of power supply, lifetime counter is stopped, when having carried out at short notice in the situation of power connection and disconnection, the recruitment that makes lifetime counter is during more than normal conditions, in the situation that reduce brightness, while making the recruitment of lifetime counter be less than normal conditions.
In addition, following situation has been described in the present embodiment, described recording unit record is from the life-span count information of described time instrumentation section, and regularly to described judging service life section, sends the life-span count information.
In addition, following situation has been described in the present embodiment, described judging service life section compared in the standard life-span be judged to be with Liquid Crystal Display is set, the life-span count value of described recording unit record is near the mark in the situation in life-span very much, Liquid Crystal Display is shown and mean to have arrived the replacing information in period.
In addition, in present embodiment and later embodiment, about management object equipment, the Liquid Crystal Display of take is illustrated as example, but also can using for example at the actuating device of the running dish 101 of the car 100 interior configurations of the elevator shown in Fig. 2, car inside door 102, car inside door 102, surveillance camera 103 as management object equipment.And, also can be using the actuating device of the elevator call button 201 of the elevator floor stops 200 shown in Fig. 3, stop side door 202, stop side door 202 as management object equipment.
In addition, in the above description, in the situation that Liquid Crystal Display 1 approaches life span, judging service life section makes Liquid Crystal Display 1 display life expiration notice message, but also can replace the demonstration of life-span expiration notice message or in display life expiration notice message, judging service life section sends life-span expiration notice message to the administrative center of elevator.
As mentioned above, the life-span of Liquid Crystal Display except the energising because of main body and cold-cathode tube cause aging, also because of the inner seal member that the heating of main body and being arranged on causes under hot and humid environment aging, shorten.
In the present embodiment, from this point of view, the temperature and humidity of measuring the surrounding environment that disposes Liquid Crystal Display is described, and the measured value of serviceability temperature or humidity is carried out the example of the judging service life of Liquid Crystal Display.
In addition, the temperature and humidity of the surrounding environment of Liquid Crystal Display 1, except near temperature and humidity Liquid Crystal Display 1, also comprises the temperature and humidity on surface of Liquid Crystal Display 1 and the temperature and humidity of Liquid Crystal Display 1 inside.
Fig. 6 means that the liquid crystal of present embodiment is controlled and the topology example of actuating device 2.
In Fig. 6, relatively the change part of Fig. 1 is ambient temperature and hygroscopy section 4 and ambient condition information 10, except ambient temperature and hygroscopy section 4 identical with Fig. 1 with the feature ambient condition information 10, so omission illustrates.
Ambient temperature and hygroscopy section 4 have temperature sensor and humidity sensor, measure be arranged in lift car and the Liquid Crystal Display 1 of stop around temperature and humidity, and to the time instrumentation section 3 be provided for notifying the ambient condition information 10 of measured value.Ambient temperature and hygroscopy section 4 are examples of surrounding environment determination part.
In addition, in the present embodiment, the time, instrumentation section 3 was according to the measured value by ambient temperature and hygroscopy section 4 notices, derivation life-span count value (aging evaluation number).
Specifically, in the measured value by ambient temperature and hygroscopy section 4 notices, not in the situation that in predetermined standard range, the time, the life-span count value additional to the life-span count value based on current"on"time 3 derived in instrumentation section.
For example, in the situation that the temperature around the Liquid Crystal Display 1 of being measured by ambient temperature and hygroscopy section 4 for example, higher than the standard temperature (being more than 60 ℃) that Liquid Crystal Display 1 is set, time, T3 second was derived by instrumentation section 3, in the situation that for example, lower than described standard temperature (being below-30 ℃), time, T4 second was derived by instrumentation section 3, the humidity of environment is for example, higher than in the situation of the standard humidity that Liquid Crystal Display 1 is set (be more than 90%RH) around, 3 derivation T5 seconds of instrumentation section time.
When in the situation that switched under the environment of hot and humid, low temperature, there is the especially trend of the aging quickening of cold-cathode tube, so by the number of seconds of T3 and T4, T5 and common count value T second of current"on"time (by T second current"on"time of power monitoring section 14 notices) the phase Calais (for example count, T3=2 second, T4=3 second, T5=4 second).
As a result, temperature or ambient humidity, light and temperature, not in the situation that in standard range, in the mode of T+T3 (2 seconds), T+T4 (3 seconds), T+T5 (4 seconds), increase while making lifetime counter than normal conditions sooner around.In addition, also can be made as T3=T4=T5.
In addition, in the situation that under the state of a half intensity or repeatedly carry out at short notice power connection/disconnection, time, instrumentation section 3 was made as the life-span count value in the situation of T1 second or T2 second, also to T1 second or T2, add the number of seconds of either party in T3～T5 second, increase sooner while making lifetime counter than normal conditions.
Below, time instrumentation section 3 the action example of present embodiment is described with reference to Fig. 7.
In Fig. 7, step S101～S106 is identical with the processing shown in Fig. 4 with S107, and the life-span counting appended in the present embodiment based on surrounding environment is processed (S301).
In the present embodiment, in the situation that not from power monitoring section 14 input energising historical informations 9 (S101: no), time instrumentation section 3 for example every some cycles from ambient temperature and hygroscopy section 4 input ambient condition information 10, and the measured value meaned according to inputted ambient condition information 10, carry out the derivation of life-span count value.
In addition, time, instrumentation section 3 was after the counting that makes lifetime counter increases (either party in S104～S106), the measured value of Liquid Crystal Displays 1 temperature and humidity is on every side inquired by temperature and hygroscopy section 4 towards periphery, input ambient condition information 10, and the measured value meaned according to inputted ambient condition information 10, carry out the derivation of life-span count value.
Below, use Fig. 8 explanation to be processed the particular case of (S301) by the time life-span counting based on surrounding environment that carries out of instrumentation section 3.
At first, instrumentation section 3 is from ambient temperature and hygroscopy section 4 input ambient condition information (S401) time.Time, instrumentation section 3 was according to noted earlier, in the situation that not from power monitoring section 14 input energising historical informations 9, input ambient condition information 10 every some cycles from ambient temperature and hygroscopy section 4, in the situation that the lifetime counter counting is increased, the measured value of the temperature and humidity around temperature and hygroscopy section 4 inquiry Liquid Crystal Displays 1, input ambient condition information 10 towards periphery.In addition, the input mode of ambient condition information 10 is not limited to this.
Then, time, instrumentation section 3 judged that whether for example, higher than the upper limit (60 ℃) of standard temperature (S402) mensuration temperature that ambient condition information 10 mean, in the situation that measure the upper limit (S402: be) of temperature higher than standard temperature, the life-span count value is made as to T3 second, makes lifetime counter increase T3 second (S405).
And, time, instrumentation section 3 measured temperature in the situation that (S402: no) below the upper limit of standard temperature being judged to be, judge that whether for example, lower than the lower limit (-30 ℃) of standard temperature (S403) mensuration temperature that ambient condition information 10 means, in the situation that measure the lower limit (S403: be) of temperature lower than standard temperature, the life-span count value is made as to T4 second, makes lifetime counter increase T4 second (S406).
And, time, instrumentation section 3 judged that whether for example, higher than the upper limit (90%RH) of standard humidity (S404) mensuration humidity that ambient condition information 10 mean, in the situation that measure the upper limit (S404: be) of humidity higher than standard humidity, the life-span count value is made as to T5 second, makes lifetime counter increase T5 second (S405).
In addition, in the situation that energising historical information 9 is expressed the current"on"time of switching on about repeatedly, carry out the processing of step S102～S301 for each current"on"time, obtain the life-span count value T～T2 for each current"on"time in current"on"time repeatedly, obtain additive value T3～T5 simultaneously, the lifetime counter counting is increased.
Later action is identical with embodiment 1, life-span count information 13 is obtained and recorded to recording unit 5, judging service life section 6 carries out the comparison of lifetime data and integral age count information 12, judge the replacing period of Liquid Crystal Display 1, in the situation that Liquid Crystal Display approaches life span, the more message of switching liquid crystal display 1 (life-span expiration notice message) is urged in generation, makes Liquid Crystal Display 1 show this message.
Like this, in the present embodiment, temperature, humidity around Liquid Crystal Display are brought impact to the life-span of Liquid Crystal Display, so except current"on"time, also temperature, humidity around Liquid Crystal Display are embodied in the life-span count value, thus can be specifically and exactly instrumentation because of the life-span of the different and different Liquid Crystal Display of the stop environment that place and elevator are set of elevator.
As a result, can prevent from missing change regularly, because placing no matter the not bright light caused, the Visual Confirmation decline that causes because of point defect bad.
And due to the confirmation (confirmation has or not point defect, line defect etc.) of having saved record to year number is set and picture, these grasp the replacing thing in period, so can expect the raising of maintenance efficiency.
And, in the above description, T3～T5 is made as to additive value, but also can be made as the coefficient multiplied each other with T current"on"time (or T1, T2) to T3～T5.For example, can be made as T3=0.5 in the situation that measure the be above standard upper limit of temperature of temperature, and make the counting of lifetime counter increase T * T3 current"on"time (0.5) second (i.e. 1.5 * T second).
And in the above description, additive value T3～T5 is respectively fixing value, but also can change additive value according to the deviation with standard temperature, standard humidity.
For example, in the situation that measure the difference of the upper limit of temperature and standard temperature, be to be less than 5 degree, can be made as T3=2 second, be more than 5 degree and be less than 10 degree in the situation that measure the difference of the upper limit of temperature and standard temperature, be made as T3=3 second.
