User's quantity Pc is meant the user's quantity P0 that utilizes escalator 100 simultaneously simultaneously.Simultaneously user's quantity Pc is to t at any time
cThe end of the mobile moving-wire Lr quantity that is in the user R between using escalator mouth line Lin and the following ladder way line Lout calculate and draw.
The deterioration that user's quantity P0 of above-mentioned each condition give to constitute the equipment of escalator 100, promptly constitute parts is brought bigger influence.User's quantity P0 of above-mentioned each condition more for a long time, compare with the situation that user's quantity P0 of above-mentioned each condition is less, load for escalator 100 increases, load to escalator 100 increases, and has therefore promoted to constitute the deterioration of parts accordingly with user's quantity P0 of above-mentioned each condition.Therefore, the judge index value Xf that calculates based on user's quantity information P can be used as the value that accurate reflection constitutes the deterioration of parts.Therefore, by can be used as the information that accurate reflection constitutes the deterioration of parts by preventive maintenance information in the period G that sets based on the judgement of judge index value Xf.Especially, simultaneously user's quantity Pc gives the equipment that constitutes escalator 100, the deterioration that promptly constitutes parts brings bigger influence.User's quantity Pc compares with the situation that while user quantity Pc is less more for a long time simultaneously, for the temporary transient load increase of escalator 100, to the temporary transient load increase of escalator 100, therefore promotes to constitute the deterioration of parts aperiodically.Therefore, the judge index value Xf that calculates based on the user's quantity information P that comprises while user's quantity information Pc can be used as the value that accurate reflection constitutes the deterioration of parts.Therefore, by can be used as the information that accurate reflection constitutes the deterioration of parts by preventive maintenance information in the period G that sets based on the judgement of judge index value Xf.
Position attribution information Pd is based on the information of each user R with respect to the position of escalator 100, also is the information of giving user's quantity P0 position attribution of each condition.Position attribution information Pd is with the position of user R with respect to the pedal 101 of escalator 100, for example is divided into the information of right side user Rdr, left side user Rdl.That is, user's quantity P0 of each condition can be divided into right side user's quantity Pdr and left side user's quantity Pdl according to position attribution information Pd.Position attribution information Pd can judge based on mobile moving-wire Lr and the predefined centre line L c that is stored in storage part 3b of for example user R.Specifically, if mobile moving-wire Lr is positioned at the right side of centre line L c with respect to service direction De, then user R is judged as the right side user Rdr on the right side of the pedal 101 of taking escalator 100, and user R is counted as right side user's quantity Pdr.If mobile moving-wire Lr is positioned at the left side of centre line L c with respect to service direction De, then user R is judged as the left side user Rdl in the left side of the pedal 101 of taking escalator 100, and user R is counted as left side user's quantity Pdl.If mobile moving-wire Lr and centre line L c report to the leadship after accomplishing a task, can based among the mobile moving-wire Lr at the partial sum on service direction De right side ratio in the part in service direction De left side, judge that right side user Rdr still is left side user Rdl.For example, if the part on the left of service direction De is more than the part on service direction De right side among the mobile moving-wire Lr, then be judged as left side user Rdl.
The deterioration that position attribution information Pd give to constitute the equipment of escalator 100, promptly constitute parts is brought bigger influence.For example,, compare with left side user's quantity Pdl under the more situation of right side user's quantity Pdr, just be greater than load for the left side for the load on the right side of the service direction De of escalator 100 for user's quantity P0 of each condition.That is, because the load on the service direction De right side of escalator 100 greater than the load in service direction De left side, makes the deterioration of the formation parts that constitute the service direction De right side in the parts greater than the deterioration of the formation parts in service direction De left side.Therefore, by comprising position attribution information Pd, make the determination flag value Xf that is calculated based on user's quantity information P can be used as the accurate value that has reflected the deterioration of the formation parts that change with respect to the position of escalator 100 because of user R as user's quantity information P.Therefore, according to preventive maintenance information in the period G that sets based on the judgement of judge index value Xf can be used as accurate reflected because of user R with respect to escalator 100 the information of deterioration of the formation parts that change of position.
Mobile status attribute information Pe is based on the information of each user R with respect to the mobile status of escalator 100, also is the information that the user's quantity P0 to each condition gives the mobile status attribute.Mobile status attribute information Pe be with user R according to mobile status with respect to escalator 100, the information that is divided into for example static user Res, walking user Rew, runs row user Rer and retrograde user Rei.That is, user's quantity P0 of each condition can be divided into static user's quantity Pes, walking user quantity Pew based on mobile status attribute information Pe, run row user quantity Per and retrograde user's quantity Pei.Mobile status attribute information Pe can judge based on speed Vr, the moving direction Dr of for example user R, the running velocity Ve and the service direction De of escalator 100.Specifically, if speed Vr equals running velocity Ve (Vr=Ve), then user R is judged as the static user Res that remains static when using escalator 100, and user R is counted as static user's quantity Pes.Speed Vr surpasses running velocity Ve, but less than predefined by running velocity Ve, as to have added the race line speed Vs that is stored in storage part 3b (based on the value of the race line speed of user R) specified speed Vm (during Ve＜Vr＜Vm), then user R is judged as the walking user Rew that is in the walking state when escalator 100 utilizes, and user R is counted as walking user quantity Pew.Specifically, (Vr＞Vm), then user R is judged as and is in the race row user Rer that runs the row state when using escalator 100, and user R is counted as running row user quantity Per if speed Vr surpasses specified speed Vm.(Vr＜Ve), then user R is judged as the retrograde user Rei that is in the state of driving in the wrong direction when using escalator 100, and user R is counted as retrograde user's quantity Pei if speed Vr does not reach running velocity Ve.
The deterioration that mobile status attribute information Pe give to constitute the equipment of escalator 100, promptly constitute parts is brought bigger influence.For example, user's quantity P0 for each condition, walking user quantity Pew, race row user quantity Per are more for a long time, compare with the situation that static user's quantity Pes is more, impact to escalator 100 increases, load to escalator 100 increases, and therefore can promote to constitute the deterioration of parts.Therefore, as user's quantity information P, by comprising mobile status attribute information Pe, the value of the deterioration of the formation parts that the determination flag value Xf that calculated based on user's quantity information P can be changed with respect to the mobile status of escalator 100 according to user R as accurate reflection.Therefore, can be used as the information of the deterioration of the formation parts that accurate reflection changes with respect to the mobile status of escalator 100 according to user R by preventive maintenance information in the period G that sets based on the judgement of judge index value Xf.
Using form attribute information Pf to be based on the information of each user R with respect to the running condition of escalator 100, also is the information of user's quantity P0 of each condition being given use form attribute.Using form attribute information Pf is with the running condition of user R according to escalator 100, for example is divided into the information of user Rfn, carrying user Rfc separately.That is, user's quantity P0 of each condition can be according to using form attribute information Pf to be divided into independent user's quantity Pfn and carrying user quantity Pfc.Use form attribute information Pf to judge based on the 3D shape that from the distribution of the time serial message U of each user R, for example three-dimensional information, extracts with the cooresponding part of user R.Specifically, if from the distribution of three-dimensional information, extract with the cooresponding part of user R 3 the dimension shapes be cylindrical, then be judged as the not independent user Rfn of carrying article on escalator 100, user R is counted as independent user's quantity Pfn.If the 3D shape that from the distribution of three-dimensional information, extracts with the cooresponding part of user R be cylindrical and cuboid (for example, pairing shapes such as hand barrow, perambulator, flat truck) continuous shape, then be judged as the carrying user Rfn of carrying article on escalator 100, user R is counted as carrying user quantity Pfc.
The equipment that uses form attribute information Pf to give to constitute escalator 100, the deterioration that promptly constitutes parts are brought bigger influence.For example, for user's quantity P0 of each condition, carrying user quantity Pfc more for a long time, compare with the situation that independent user's quantity Pfn is more, load for escalator 100 increases, and to the load increase of escalator 100, can promote to constitute the deterioration of parts.Therefore, as user's quantity information P, use form attribute information Pf by comprising, can be with the determination flag value Xf that calculated based on user's quantity information P value as the deterioration that accurately reflects the formation parts that change with respect to the running condition of escalator 100 according to user R.Therefore, can be with the information of the deterioration of the formation parts that change with respect to the running condition of escalator 100 according to user R as accurate reflection by preventive maintenance information in the period G that sets based on the judgement of judge index value Xf.
Handling part 3a calculates preventive maintenance relevant judge index value Xf in period with escalator 100 based on user's quantity information P, and when the judge index value Xf that calculates surpasses threshold X t preventive maintenance information in period G is set.Here, preventive maintenance information in period G comprises escalator 100 integral body or the preventive maintenance period of the next time that constitutes parts arbitrarily more than 1.And, interimly when the preventive maintenance of next time include next inspection period, the information in period more than at least 1 in next maintenance period, next replacing period etc.G has been set and has been stored under the situation of storage part 3b in preventive maintenance information in period, when handling part 3a sets new preventive maintenance information in period G, preventive maintenance information in the period G that has set to be replaced with new preventive maintenance information in period G, promptly preventive maintenance information in period G be upgraded.
When handling part 3a calculates determination flag value Xf based on 1 user's quantity information P, for example calculate maxim Pam since user's quantity Pa of each unit time of the preventive maintenance of last time, the maxim Pcm etc. of user's quantity Pc and sets preventive maintenance information in period G when determination flag value Xf surpasses threshold X t as determination flag value Xf since the accumulation user quantity Pb of the preventive maintenance of last time, since the preventive maintenance of last time the time.Here, threshold X t be meant whole with escalator 100 or the inspection that constitutes parts arbitrarily, escalator 100 or the maintenance of the next time that constitutes parts arbitrarily more than 1 more than 1, the replacing of the next time that constitutes parts arbitrarily more than 1 in more than at least 1 desired period corresponding value.During determination flag value Xf that use is calculated based on 1 user's quantity information P, can select than being used as threshold value with the big value of cooresponding value in the period of described requirement.
Handling part 3a calculates when judging desired value Xf based on 1 user's quantity information P and user's quantitative forecast information Pg, for example calculate add user's quantitative forecast information Pg since the accumulation user quantity Pb of the preventive maintenance of last time value as determination flag value Xf, and when judging that desired value Xf surpasses threshold X t, preventive maintenance information in period G is set.That is, handling part 3a is according to calculating judgement desired value Xf based on 1 user's quantity information P and user's quantitative forecast information Pg, and G sets to preventive maintenance information in period, therefore can set preventive maintenance information in period G in advance.User's quantitative forecast information Pg is user's quantity P0 of escalator 100 in the future, is based on that the preventive maintenance information H in the past that comprises preventive maintenance information in period G in the past or among user's quantity information P in the past at least one calculate.The preventive maintenance information H in past and user's quantity information P in the past are stored in storage part 3b.The preventive maintenance information H in past also comprises preventive maintenance enforcement place, the information such as preventive maintenance implementation content in past in the past except preventive maintenance information in the period G in past.User's quantitative forecast information Pg be past of calculating of the user's quantity information P according to the past arbitrarily during average value P aa, the user's quantity Pab of one day tomorrow doping according to user's quantity information P in past etc. of user's quantity Pa of every day.
When handling part 3a calculates judgement desired value Xf based on a plurality of user's quantity information P, for example calculate accumulation user quantity Pb since the preventive maintenance of last time, since the walking user quantity Pew of the preventive maintenance of last time, since the aggregate value of right side user's quantity Pdr of the preventive maintenance of last time as judge desired value Xf (=Pb+Pew+Pdr), and when determination flag value Xf surpasses threshold X t, preventive maintenance information in period G is set.Thus, handling part 3a can set preventive maintenance information in period G exactly based on the judgement desired value Xf of the service condition of having considered escalator 100.When coming computational discrimination desired value Xf based on a plurality of user's quantity information P, the weighted sum that can calculate each user's quantity information P is as judging desired value Xf.When calculating judgement desired value Xf by weighted sum, handling part 3a for example calculate since the accumulation user quantity Pb of the preventive maintenance of last time multiply by weight a value, multiply by the value of weight b, multiply by the aggregate value of value of weight c since right side user's quantity Pdr of the preventive maintenance of last time since the walking user quantity Pew of the preventive maintenance of last time as judging desired value Xf (=a * Pb+b * Pew+c * Pdr, a+b+c=1 here).Because can promote the deterioration that constitutes parts to bring user's quantity information P of less influence to change weight bring user's quantity information P of considerable influence and give for the deterioration that promotes the formation parts, therefore the judgement desired value Xf based on the service condition of having considered escalator 100 can further set preventive maintenance information in period G exactly.Further, the weighted sum that calculates each user's quantity information P can change according to the variation of user's quantity information P arbitrarily with the cooresponding weight of user's quantity information P arbitrarily when judging desired value Xf.For example, arbitrarily user's quantity information P be since last time user's quantity Pc preventive maintenance the time maxim Pcm the time, weight increases along with the increase of maxim Pcm.Specifically, maxim Pcm is that 1～10 o'clock weight is that 0.1,11～15 o'clock weight is that 0.2,16 weight when above is 0.5.Arbitrarily user's quantity information P be since last time preventive maintenance carrying user quantity Pfc the time, weight increases along with the increase of carrying user quantity Pfc.Specifically, carrying user quantity Pfc is that 1～1000 o'clock weight is that 0.1,1001～2000 o'clock weight is that 0.2,2001 weight when above is 0.5.And, after the cooresponding weight of user's quantity information P has changed arbitrarily, in order to be that weight adds up to 1, other also will change with the cooresponding weight of user's quantity information P.In addition, handling part 3a also can calculate judgement desired value Xf based on a plurality of user's quantity information P and a plurality of user's quantitative forecast information Pg.
Here, judging that desired value Xf can be not only one, also can be a plurality of.At this moment, handling part 3a calculates respectively based on user's quantity information P and judges desired value Xf

Below, an example of the setting process of preventive maintenance information in the period G of the preventive maintenance support system 1 of this example is described.Fig. 6 be illustrate preventive maintenance information in period setting process the figure of an example.Fig. 7 is the figure of an example that user's quantity of one day is shown.Fig. 8 is the figure that illustrates since an example of the accumulation user quantity of the preventive maintenance of last time.Following setting process is to describe particularly calculating the situation of judging desired value Xf based on 1 user's quantity information P and user's quantitative forecast information Pg.
As shown in Figure 6, handling part 3a at first obtains the time serial message U (step ST21) of each user R.
Then, handling part 3a calculates user's quantity Pa (step ST22) of unit time.Here, handling part 3a calculates user's quantity Pa of one day.As shown in Figure 7, user's quantity Pa of one day be meant from the morning 00:00 to the user's quantity P0 the 24:00 (00:00 in the morning of next day).
Then, as shown in Figure 6, handling part 3a calculates the accumulation user quantity Pb (step ST23) since the preventive maintenance of last time.Here, handling part 3a adds up by user's quantity Pa of one day that the preventive maintenance to last time is calculated later, calculates since the accumulation user quantity Pb of the preventive maintenance of last time.As shown in Figure 8, be meant user's quantity P0 since the anti-accumulation user quantity Pb that safeguards of giving of last time from the preventive maintenance day T0 of last time to Tn today.
Then, as shown in Figure 6, handling part 3a calculates and judges desired value Xf (step ST24).Here, handling part 3a calculates the value of average value P aa addition of user's quantity Pa of one day since the preventive maintenance day T0 of the accumulation user quantity Pb of the preventive maintenance of last time and last time to Tn today, as judging desired value Xf.
Then, whether handling part 3a judges (step ST25) above threshold X t to the judgement desired value Xf that calculates.
If handling part 3a judges the judgement desired value Xf that calculates and surpasses threshold X t (step ST25 affirms), then sets preventive maintenance information in period G (step ST26).Here, if handling part 3a judge as since the preventive maintenance of last time to tomorrow Tn+1 the judgement desired value Xf of accumulation user quantity Pb surpass threshold X t, then set tomorrow Tn+1 as for example preventive maintenance day (information in period) of next time.If handling part 3a judges that the judgement desired value Xf that calculates smaller or equal to threshold X t (step ST25 negates), then finishes the setting of preventive maintenance information in period and handles.
Period, information setting device 3 outputed at least one side in office terminal 4 or the portable terminal device 5 with preventive maintenance information in the period G that sets.At least one side's output preventive maintenance information in period G in office terminal 4 or the portable terminal device 5.Even output preventive maintenance information in period G the user can export preventive maintenance information in period G with discerning and is exactly, show following information: for example, the calling hierarchy (every kind of calling hierarchy shows with digital, color) of the preventive maintenance day of next time, the present preventive maintenance that calculates period based on the preventive maintenance of next time, the appointment of the equipment component of the replacing that calculates period based on the preventive maintenance of next time etc.These also may be displayed on the map that is provided with preventive maintenance support system 1 cooresponding escalator 100.
As mentioned above, adopt the preventive maintenance support system 1 of this example, the user can be based on user's quantity information P, promptly preventive maintenance information in the period G that sets according to the degradation based on the formation parts of escalator 100 recognizes appropriate preventive maintenance period, therefore, can support the user makes it carry out preventive maintenance in appropriate period to escalator 100.The preventive maintenance support system 1 of this example can indicate the user to check as next preventive maintenance content for example accumulating 100 of the less escalators of user's quantity Pb, can also indicate the user that the more escalator 100 of accumulation user quantity Pb is constituted the preventive maintenance content of the replacing of parts as next time.The preventive maintenance support system 1 of this example can indicate the user that the more escalator of for example right side user quantity Pdr 100 is changed the formation parts on right sides as the preventive maintenance content of next time, can also indicate the user that user's quantity Pdl more escalator 100 in left side is changed the preventive maintenance content of the formation parts in left side as next time.
This example has more than to be defined in based on user's quantity information P and calculates judgement desired value Xf, also can calculate based on the operation information W of user's quantity information P and escalator 100 and judge desired value Xf.At this moment, also can calculate 1 judge index value Xf, when judge index value Xf surpasses threshold X t, preventive maintenance information in period G be set based on the operation information W of for example user's quantity information P and escalator 100.For example, can calculate judgement desired value Xfp, calculate based on operation information W and judge desired value Xfw based on user's quantity information P respectively, and based on each judge desired value Xfp, Xfw has surpassed and each judges desired value Xfp, Xfw quantity of the judgement desired value Xf of corresponding threshold Xtp, Xtw respectively, come preventive maintenance information in period G is set.Thus, handling part 3a can correctly set preventive maintenance information in period F based on the judgement desired value Xf of the operation conditions of the service condition of having considered escalator 100 and escalator 100.
In this example, period, the event information E of the incident that information setting device 3 can change based on user's quantity P0 of escalator 100 proofreaied and correct judging desired value Xf.Event information E is stored in storage part 3b, be meant at a time the information of the incident that user's quantity P0 of joint or a period of time escalator 100 changes, corresponding to for example have a holiday for a long time (connect in golden week, summer stop, New Year etc.), Christmas, special selling meeting, concert, sport, season, weather etc.For example, at plum rain season, being got wet because of escalator 100 to promote to constitute the deterioration of parts, and therefore, handling part 3a is modified to bigger value at the judgement desired value Xf that plum rain season will calculate, and shortens during preventive maintenance period of near next time.And, in having a holiday for a long time, user's quantity P0 of escalator 100 changes, therefore, for example, under the situation that user's quantity P0 increases in having a holiday for a long time, in order before having a holiday for a long time, to reach the preventive maintenance period of next time, the judgement desired value that handling part 3a will calculate is made as bigger value, makes to shorten during preventive maintenance period of next time.Under the situation that user's quantity P0 reduces in having a holiday for a long time, in order to reach the preventive maintenance period of next time in having a holiday for a long time, the judgement desired value that handling part 3a will calculate is made as bigger value, makes to shorten during preventive maintenance period of next time.Therefore, by revising judging desired value Xf,, also can support the user and make it carry out the preventive maintenance of escalator 100 in appropriate period even make because incident changes user's quantity P0 of escalator 100 based on event information E.Event information E can set based on the calendar function that information setting device 3 in period is had.Event information E also can be set by at least one side of user from office terminal 4 or portable terminal device 5.
