In addition, being set as pinao nobile for 1 layer herein.

At the end of initial setting in S1, the explanation of Fig. 2 is then returned to, state collection portion 2 is from elevator control gear 11 according to the work state information for collecting elevator per unit time, by the work state information and collection time of the elevator being collected into It exports to state recording portion 3.State recording portion 3 determines layer according to the work state information of the elevator inputted from state collection portion 2 Whether button of standing has been pressed (S2).In the case where landing button is not pressed, i.e., in S2 in the case where branching into "No", State recording portion 3 determine until landing button is pressed.In the case where landing button is pressed, i.e., S2's In the case where branching into "Yes", state recording portion 3 stores at the time of landing button is pressed and its number of floor levels, will also receive from state The operating status record for the elevator that collection portion 2 inputs is in state accumulation unit 4 (S3).Believed according to the working condition in state recording portion 3 The reading of breath is believed according to carriage operating condition information, carriage resting state information, carriage door opening state is collected per unit time Breath, carriage shutdown status information, meausring apparatus status information, car button status information, landing button status information and carriage Door safety device status information, and carry out whether having the judgement (S4) closed the door after the variation of meausring apparatus state.It is weighing After the variation of unit state in the case where no shutdown, i.e., in S4 in the case where branching into "No", state recording portion 3 continues work Make the record of status information.That is, state recording portion 3 carries out the record of work state information, until in meausring apparatus state Until having shutdown after variation.In other words, state recording portion 3 carries out the record of work state information, until in meausring apparatus State becomes " 0 " as until not becoming carriage shutdown state after the state of passenger in carriage from " 1 ".

In the case where having shutdown after the variation of meausring apparatus state, i.e., in S4 in the case where branching into "Yes", shape At the time of the landing button inputted from state collection portion 2 is pressed by state record portion 3, the number of floor levels that landing button is pressed and to The work state information of the number of floor levels reached and the elevator being collected into, the boarding state as elevator are stored in state accumulation unit 4 In (S5).In addition, the capture range of the boarding status information of the elevator of the record of state recording portion 3 is shown in FIG. 5.In Fig. 5 In about capture range, will be from the carriage calling movement carried out using landing button to taking into the passenger of carriage under arrival floor Ladder and car door are shown as capture range until closing.The elevator movement of capture range is as described below.Firstly, pressing lower layer in passenger Stand button when, carriage is moved to the floor of pressed landing button.Then, car door opens the door, and passenger takes into carriage.Also, Operation panel 13 carries out the shutdown of destination floor selection and car door in passenger operation carriage.Finally, in carriage to destination building After layer is mobile, car door opens the door, and passenger is withdrawn into the stop of destination floor from carriage.

State recording portion 3 generates admin number in the record of boarding status information, at the time of landing button is pressed It moves the moment, the number of floor levels i.e. arrival floor for the number of floor levels i.e. departure floor and arrival that landing button is pressed, stores respectively In the moving condition management table that state accumulation unit 4 shown in Fig. 3 is accumulated.Also, state recording portion 3 is by admin number and shape Carriage operating condition information, the carriage resting state information, carriage door opening state information, carriage shutdown shape of the collection of state collection portion 2 State information, meausring apparatus status information, car button status information, landing button status information and carriage door safety device state Information is stored respectively in the boarding condition management table that state accumulation unit 4 shown in Fig. 4 is accumulated.In addition, car button state Information includes destination floor button information, door open button status information and door close button status information.

Then, abnormality determination unit 5 carries out the calculating (S6) of action frequency.That is, according to the elevator stored in state accumulation unit 4 Boarding status information, carry out the action frequency slave device number No. 1 to No. n device of device management table shown in fig. 6 It calculates.Fig. 9 is the flow chart for showing calculating action number.It is started to process from the device that device number is No. 1, abnormal determination first Portion 5 determines whether current device number is n or less (S101), in the case where current device number is not n situation below (S101: no) is ended processing.In the case where current device number is n situation below (S101: yes), abnomal results condition pipe is carried out The reading of table is managed, the abnormal device of detection is obtained and numbers (S102).Then, abnormality determination unit 5 reads moving condition and manages table, takes Obtain departure floor and arrival floor (S103).Then, abnormality determination unit 5 reads boarding condition management table, carries out the change of projects The statistics (S104) for changing number, then returnes to S101.As a specific example, to " 5 " button exception for determining main controlling board Situation is illustrated.It is device number " 7 " in " 5 " button of main controlling board device management table shown in Fig. 6.Therefore, abnormal Determination unit 5 calculate abnomal results condition management table shown in Fig. 7 device number be " 7 " state of elevator action frequency.Root According to Fig. 7, the project that should calculate action frequency includes: main controlling board " 5 " button when being moved to 5 layers from pinao nobile, from 5 layers of movement Main controlling board " pinao nobile " button when to pinao nobile, carriage operating when being moved to 5 layers from pinao nobile, from 5 layers to pinao nobile Carriage operating when mobile, secondary operation panel " 5 " button when being moved to 5 layers from pinao nobile are pressed, are mobile from 5 layers to pinao nobile When landing button when pressing, being moved to 5 layers from pinao nobile of secondary operation panel " pinao nobile " button press and from 5 layers Landing button when being moved to pinao nobile is pressed.Abnormality determination unit 5 is from moving condition management table collection shown in Fig. 3 building Layer and arrival floor are collected each state of elevator from the boarding condition management table shown in Fig. 4 accumulated in state accumulation unit 4, are calculated Projects of state of elevator add up from the number that " 0 " variation is " 1 " and from the number that " 1 " variation is " 0 ".Abnormality determination unit Calculated number is stored in abnomal results condition management table that abnomal results condition storing section 6 shown in Fig. 7 is accumulated by 5 In the project of action frequency.Also, all devices number in device management table shown in fig. 6 is similarly operated.

Then, abnormality determination unit 5 carries out the action frequency of the PBU pushbutton unit as supervision object and examines with exception is corresponded to Out the supervision object device of condition operate associated device action number ratio whether Yi Chang judgement (S7).That is, abnormal Determination unit 5 is according to the exception of the action frequency decision maker counted.Here, working as in the boarding state of elevator according to each dress Set calculated action frequency comply with normal distribution, object apparatus action frequency not in the range of ± 3 σ in the case where, sentence It is set to exception.In addition, σ indicates that standard deviation can enumerate use from being arranged device about the calculating of standard deviation as an example One month during record every day device action number result and determine the abnormal date device action number side Method.Here, using 3 σ as determinating reference value, however, the present invention is not limited thereto is also possible to σ, 2 σ, 4 σ, can also be bigger value. As an example, the action frequency of main controlling board " 5 " button is 2 times in fig. 8, and with the supervision object of corresponding abnomal results condition The average value of the associated device of operation compare, except the range of ± 3 σ, thus abnormality determination unit 5 is determined as exception.That is, Abnormality determination unit 5 uses supervision object device corresponding with the abnomal results condition accumulated in abnomal results condition storing section 6 Action frequency and abnomal results condition, the action frequency for calculating supervision object device and operation phase with the supervision object device Associated device action number is simultaneously compared, and thus determines the exception of supervision object device.In addition, being pressed in main controlling board " 5 " The action frequency of button lower than the action frequency of other state of elevator it is average in the case where, but often break when that should be set as and connect It opens, thus abnormality determination unit 5 is determined as that main controlling board " 5 " button is to disconnect failure.Also, in the dynamic of main controlling board " 5 " button Make number more than the action frequency of other state of elevator it is average in the case where, it is believed that although not carrying out being set as connecting or disconnected But on-off repeatedly is opened, thus abnormality determination unit 5 is determined as that main controlling board " 5 " button is the failure of on-off repeatedly.That is, Abnormality determination unit 5 can according to the PBU pushbutton unit state for the elevator accumulated in state accumulation unit 4, the carriage moving condition of elevator and The open and-shut mode of car door differentiates the disconnection failure and the failure of on-off repeatedly of PBU pushbutton unit.Elevator point inspection device as a result, 1 can automatically detect the disconnection failure of PBU pushbutton unit and the repeatedly failure of on-off, and can differentiate it is any failure shape State.Then, in the case where ratio does not have exception, i.e., in the case where branching into "No" in S7, back to the landing button of S2 The judgement whether being pressed.In the case where ratio exception, i.e., in the case where branching into "Yes" in S7, abnormality determination unit 5 To abnormal notification unit 7 send the device number of the device for being judged as being abnormal, device name, action frequency and with quilt The average value of the action frequency of the associated device of the device for being judged to being abnormal.In this way, abnormality determination unit 5 determines and exception The working condition of the working condition of the corresponding supervision object device of detection condition and device associated with the supervision object device It is whether consistent, and it is sent to abnormal notification unit 7.

Then, abnormal notification unit 7 carries out abnormal notice (S8).That is, abnormal notification unit 7 will be received from abnormality determination unit 5 To be judged as have occurred abnormal device device number and make landing display device 15 destination floor arrow dodge Bright instruction is sent to landing display device 15 via elevator control gear 11.In addition, abnormal notification unit 7 will be from abnormal determination Device number that portion 5 received be judged as having occurred abnormal device, device name, action frequency and be determined For the average value of the action frequency for the associated device of device being abnormal, it is also sent to the abnormal receiving unit of monitoring terminal 10 9。

Figure 10 is to show the abnormal output of notification unit 7 to the figure of an example of the information of landing display device 15.Elevator is waited to arrive The arrow of the destination floor of the passenger reached according to Fig.10, flashes, and can learn that failure has occurred in elevator.Figure 11 is to show Figure of the abnormal output of notification unit 7 to an example of the information of monitoring terminal 10.By show as shown in figure 11 be judged as occurring it is different Device number, device name, action frequency and the device associated with the device for being judged as being abnormal of normal device Action frequency average value, the user of monitoring terminal 10, typically say be elevator administrator or security official can Learn that failure has occurred in elevator.Also, it, can about the action frequency of device associated with the device for being judged as being abnormal Not show average value, and show the everything number that the 2nd row of abnomal results condition management table shown in Fig. 8 rises.In addition, Abnormal notification unit 7 can be the structure all notified landing display device 15 and monitoring terminal 10, be also possible to only notify To the structure of either side.

As above in present embodiment 1 illustrate as, be capable of providing can detect automatically influence elevator movement The elevator point inspection device of failure.
