Detailed description of the invention
Suitably carry out the explanation as the embodiment of an example of the present invention with reference to accompanying drawing below.
(the first embodiment)
Fig. 1 represents the schematic configuration example of the drg abnormality detection system of the elevator in the first embodiment.Car 102 is captured in not shown car frame, and the motor of the car frame of one end that is installed on main rope 104 by the propulsion source that makes elevator and travel and the towing machine 106 with the rope sheave of hanging main rope travel in elevating road (not shown).Other end hanging balancing at main rope weighs 108.The switching of the drg 110 of the rotation of the rotation of towing machine 106 and braking towing machine 106 is controlled by elevator control gear 112.At this, for the purpose of simplifying the description, a drg 110 is only shown in the drawings, but the viewpoint of the safety moving from elevator arranges multiple drgs conventionally.Elevator control gear 112 by control towing machine 106 car 102 is travelled, arrive at layer stop.
Drg working state detection device 114 detects the open and-shut mode of drg 110.At this, the state that closes of drg 110 means that drg 110 has applied the state of braking in order to brake the rotation of towing machine 106, and the state of opening of drg 110 means the state that drg 110 does not apply.Temperature-detecting device 116 detects the temperature of drg 110.Temperature-detecting device 116 is for example by being installed on thermally dependent resistor, diode or the thermocouple equitemperature sensor of drg 110 and determining that according to the temperature information of the drg 110 from temperature sensor output the temperature detection unit of the temperature of drg 110 forms.Temperature detection unit is by testing in advance, resolve or the temperature information based on being detected by temperature sensor such as simulation being determined the temperature of drg 110.
The temperature information of the drg 110 being detected by temperature sensor 116 is passed to a reference value determination device 118 of a reference value (below sometimes referred to as a reference value) of the normality that determines the work-hours for judging drg 110.On a reference value determination device 118, be connected with a reference value data storage apparatus 120, this a reference value data storage apparatus by a reference value the data definite temperature characterisitic based on drg work-hours and temperature correlation connection preserve, this drg work-hours is from exporting the drg work order of closed drg 110 till drg 110 becomes the time of the state of closing by elevator control gear 112.In a reference value data storage apparatus 120, comprise non-volatile semiconductor memory or the magnetic storage mediums etc. such as flash memory.
One example of the temperature characterisitic of drg work-hours is shown by dot-dash curve 202 in Fig. 2.In one embodiment, the error detection of the drg abnormal work that the error causing for fear of state-detection cycle time or both sides' reason of the individual difference based on each drg or drg working state detection device 114 causes, more than needed, the slightly large value of ratio braking work-hours that a reference value corresponding with a reference value data that are stored in a reference value data storage apparatus 120 is set as having.For example, in the time that the temperature of drg 110 is To, drg work-hours is δ, and a reference value is made as δ '.In the case, the curve 204 of the temperature dependency of a reference value corresponding with a reference value data that are stored in a reference value data storage apparatus 120 as shown in the solid line of Fig. 2.
In other embodiments, the temperature dependency of a reference value corresponding with a reference value data that are stored in a reference value data storage apparatus 120 represents with step-characteristic.In the case, the step function 302 of the temperature characterisitic of drg work-hours as shown in Fig. 3 dotted line.In which, range of temperatures desirable drg 110 is divided into multiple regions, drg work-hours in each temperature province being divided into is made as to certain value.For example, as shown in Figure 3, the approximate drg work-hours of temperature province a, b, c is made as respectively α, β, γ.The a reference value corresponding with a reference value data that are stored in a reference value data storage apparatus 120 is set as having more than needed, slightly larger than drg work-hours value.For example, as shown in Figure 3, a reference value of temperature province a, b, c is made as respectively to α ' (α ' > α), β ' (β ' > β), γ ' (γ ' > γ).In the case, the step function 304 of the temperature dependency of a reference value corresponding with a reference value data that are stored in a reference value data storage apparatus 120 shown in solid line in Fig. 3.Actual drg characteristic is not the such step-characteristic of step function 302 shown in Fig. 3 dotted line, but can simplify setting by being made as step-characteristic.The approximate drg work-hours of each range of temperatures being divided into or a reference value can be made as aviation value or the maxim of each temperature province.In addition can also determine by method of least square.In addition, drg work-hours under the boundary temperature of adjacent temperature province or a reference value can be made as drg work-hours or a reference value of either party's temperature province, or are made as the intermediate value of the work-hours of two temperature provinces or the aviation value of a reference value etc.
The temperature information of the drg 110 of a reference value determination device 118 based on exporting from temperature-detecting device 116 and a reference value data that are stored in a reference value data storage apparatus 120 determine a reference value of normality of the work for judging drg 110.In one embodiment, the temperature information in the moment of a reference value determination device 118 based on the drg work order of exporting from elevator control gear 112 being detected determines a reference value.For example, in a reference value data storage apparatus 120, the curve 204 of a reference value data shown in solid line in Fig. 2, store, in the time that the brake temperature corresponding with the temperature information of the drg 110 of exporting from temperature-detecting device 116 is To, a reference value determination device 118 determines δ ' as a reference value of drg abnormality detection.In addition, in a reference value data storage apparatus 120, a reference value data are stored as the step function 304 shown in realizing in Fig. 3, the brake temperature corresponding with the temperature information of the drg 110 of exporting from temperature-detecting device 116 is in the temperature province a of Fig. 3 time, and a reference value determination device 118 determines α ' as a reference value of drg abnormality detection.
When determining that after a reference value of drg abnormality detection, a reference value of decision is delivered to drg abnormal detector 122 by a reference value determination device 118.A reference value determination device 118 for example as shown in Figure 1, is connected with elevator control gear 112, can monitor the drg work order of exporting from elevator control gear 112.In one embodiment, a reference value determination device 118 is detecting the moment of the drg work order of exporting from elevator control gear 112, and a reference value that the temperature information based on transmitting from temperature-detecting device 116 is determined is delivered to drg abnormal detector 122.In this embodiment, in the time next drg work order being detected, a reference value after renewal is delivered to drg abnormal detector 122.
Drg abnormal detector 122 receives a reference value being determined by a reference value determination device 118, and receives the open and-shut mode information of drg 110 from drg working state detection device 114.Drg abnormal detector 122 is connected with elevator control gear 112, can monitor the drg work order of exporting from elevator control gear 112.In the time drg work order being detected from elevator control gear 112, drg abnormal detector 122 instrumentations from output brake work order time be carved into the drg 110 being detected by drg working state detection device 114 state become the time drg work-hours till the state of closing.In the time of instrumentation drg work-hours, can use real-time clock (RTC) etc.Drg abnormal detector 122, by the drg work-hours of instrumentation and a reference value comparison receiving from a reference value determination device 118, judges that whether drg 110 is normal.Length at the drg work-hours of instrumentation equals or is shorter than a reference value receiving from a reference value determination device 118, is judged as drg 110 normal, end process.
In one embodiment, in the time being judged to be to exceed by the drg work-hours of drg abnormal detector 122 instrumentations a reference value receiving from a reference value determination device 118, be judged to be drg 110 abnormal, this situation is passed to elevator control gear 112.Elevator control gear 112 outputs that receive drg operation irregularity information stop the instruction of car 102.
As mentioned above, carried out the explanation as the schematic configuration example of the elevator brake abnormality detection system of an example of the present invention with reference to Fig. 1.Elevator control gear 112 shown in Fig. 1 is installed by so-called embedded system conventionally, and this embedded system comprises the software of the hardware resources such as microcomputer, ROM, RAM or magnetic memory apparatus and elevator control needs.In addition, a part for drg working state detection device 114, temperature-detecting device 116, a reference value determination device 118 and drg abnormal detector 122 also can be installed by embedded system.In addition, in Fig. 1, as the mode separating with elevator control gear 112, a reference value determination device 118, a reference value data storage apparatus 120 and drg abnormal detector 122 are shown, but also these devices can be built in to common elevator control gear.
Below with reference to an example of the work of flowchart text embodiment.Shown in 4 for the diagram of circuit of an example of work of embodiment is described.In the time exporting the drg work order of closed drg 110 from elevator control gear 112, start to change in the drg 110 of opening state the state of closing, and drg abnormal detector 122 and a reference value determination device 118 detect from elevator control gear 112 and have exported drg work order in S402.Detect that the time that the drg abnormal detector 122 of having exported drg work order starts instrumentation and becomes till the state of closing as the state of drg 110 in S404 is drg work-hours, and monitor the open and-shut mode information of the drg 110 being detected by drg working state detection device 114.At step S406, the open and-shut mode information of the drg 110 of drg abnormal detector 122 based on carrying out self brake working state detection device 114 judges whether drg 110 becomes the state of closing.Do not become while closing state when be judged as drg 110 in S406, drg abnormal detector 122 is proceeded the instrumentation of drg work-hours.Become while closing state when be judged as drg 110 in S406, work enters S408, and drg abnormal detector 122 finishes the instrumentation of drg work-hours, obtains the instrumentation result of drg work-hours.
When detecting in S402 while having exported drg work order from elevator control gear 112, with above-mentioned work concurrently, in S410, a reference value determination device 118 is read the temperature information of the drg 110 being detected by temperature-detecting device 116.Then at S412 a reference value determination device 118, the temperature information of the drg 110 based on obtaining at S410 and a reference value data that are kept at a reference value data storage apparatus 120 determine the abnormal a reference value of work for judging drg 110.In a reference value data storage apparatus 120, example is preserved a reference value data in the mode of curve 204 as shown in Figure 2, in the time that the temperature of drg 110 is To, determines δ ' as a reference value.In a reference value data storage apparatus 120, for example preserve in the mode of step function 304 as shown in Figure 3, in the time that the temperature of drg 110 is in temperature province a, determine α ' as a reference value.
The for example α ' of a reference value determining in the instrumentation result of the drg work-hours that then drg abnormal detector 122 is relatively obtained at S414 in S408 and S412.
Judge at S416 whether the drg work-hours of instrumentation equals or be shorter than a reference value of decision.In the time being judged as the drg work-hours of instrumentation at S416 and equaling or be shorter than a reference value of decision, be judged to be drg working properly.On the other hand, in the time being judged as the drg work-hours of instrumentation at S416 and being greater than a reference value of decision, be judged to be drg operation irregularity at S418.In the time being judged to be drg operation irregularity, stop the instruction of travelling of car 102 in 112 outputs of S420 elevator control gear.
According to embodiment described above, can not carry out error detection to temperature variant drg work-hours and carry out the suitable supervision of drg work.
(the second embodiment)
The schematic configuration example of the schematic configuration of the drg abnormality detection system of the elevator of the second embodiment and the first embodiment shown in Fig. 1 is same, but different from the first embodiment aspect a part of structural element and work.Therefore, centered by the aspect different from the first embodiment, describe.
In the first embodiment a reference value data storage apparatus 120 by a reference value data and temperature correlation connection preserve, in the second embodiment not only a reference value data but also the second a reference value data also with temperature correlation connection preserve.For fear of misunderstanding, in description of the present embodiment a reference value data are being designated as to the first Reference data.The value of the second a reference value data is greater than the value of first reference value data.
In Fig. 5, represent a temperature dependent example of the second a reference value data with the curve 506 of dotted line.One example of the temperature characterisitic of drg work-hours is shown by dot-dash curve 202 in the drawings simultaneously, a temperature dependent example of first reference value data is shown by block curve 204.Drg work-hours, first reference value and the second a reference value under temperature T o are respectively δ, δ 1 ', δ 2 '.Data Representation method shown in Fig. 5 is same with the Data Representation method shown in Fig. 2, clearly also can represent the second a reference value data and first reference value data with step function as shown in Figure 3.
The temperature information of the drg 110 of a reference value determination device 118 based on exporting from temperature-detecting device 116 and the first reference value data and the second a reference value data that are kept at a reference value data storage apparatus 120, not only determine that first reference value also determines the second a reference value.In one embodiment, the temperature information in the moment of a reference value determination device 118 based on the drg work order of exporting from elevator control gear 112 being detected determines first reference value and the second a reference value.For example, in a reference value data storage apparatus 120, first reference value and the second a reference value are for example stored the curve 506 shown in curve 204 and the dotted line shown in solid line in Fig. 5 respectively, when the brake temperature corresponding with the temperature information of the drg 110 of exporting from temperature-detecting device 116 is To, a reference value determination device 118 determines δ 1 ' as first reference value, determines δ 2 ' as the second a reference value.
In addition, drg abnormal detector 122 by the drg work-hours of instrumentation not only with first reference value also with the second a reference value comparison.
Below with reference to an example of the work of flowchart text the second embodiment.In Fig. 6, represent the diagram of circuit of an example of the work for the second embodiment is described.To the work mark identical with work in diagram of circuit as shown in Figure 4 and Fig. 4 with reference to label identical with reference to label.The work of S402, S404, S406, S408 is identical with content illustrated in fig. 4, enters S614 when processing finishes in S408.
In addition, the temperature information post-processing that obtains drg 110 at S410 enters S612, and the temperature information of the drg 110 of a reference value determination device 118 based on obtaining in S410 determines first reference value (for example δ 1 ') and second a reference value (for example δ 2 ') for example, with the temperature (To) of drg 110 corresponding with the first reference value data of preserving at a reference value data storage apparatus 120 and the second a reference value data.Then process and enter S614.
The first reference value and the second a reference value that in the instrumentation result of the drg work-hours of obtaining in drg abnormal detector 122 comparison S408 in S614 and S612, determine.Then, judge at S416 whether the drg work-hours of instrumentation equals or be shorter than the first reference value of decision.In the time being judged as the drg work-hours of instrumentation equaling or be shorter than the first reference value of decision in S416, be judged to be drg working properly.
On the other hand, in the time being judged as the drg work-hours of instrumentation being greater than the first reference value of decision in S416, be judged to be drg operation irregularity at S418, process and enter S620.In S620, judge whether the drg work-hours of instrumentation equals or be shorter than the second a reference value of decision.In the time judging that at S620 the drg work-hours of instrumentation equals or is shorter than the second a reference value of decision, this situation is passed to elevator control gear 112 by drg abnormal detector 122.Then in S622, elevator control gear 112 makes car 102 low speed drivings to nearest layer.In the time that car 102 arrives in nearest layer, stop the instruction of travelling of car 102 in 112 outputs of S420 elevator control gear.
In the time being judged as the drg work-hours of instrumentation at S620 and exceeding the second a reference value of decision, to process and enter S420, elevator control gear 112 outputs stop the instruction of travelling of car 102.
Embodiment according to the above description, the reasons such as gap between the dish of the pad due to drg and towing machine or drum is bad, exceed first reference value and in the case of the time drg 110 in the second a reference value is worked, to layer recently, can prevent that thus the car person of taking from closing into car by low speed driving only.
(the 3rd embodiment)
The schematic configuration of the drg abnormality detection system of the elevator of the 3rd embodiment is same with the schematic configuration example of the first embodiment shown in Fig. 1, but except the aspect difference of additional a reference value correcting device, a part of structural element is different with work.Therefore, centered by the aspect different from the first embodiment, describe.
The schematic configuration example of the drg abnormality detection system of the elevator of the 3rd embodiment shown in Fig. 7.Additional a reference value correcting device 724 in the system of the first embodiment as shown in Figure 1.The temperature dependent a reference value data of a reference value that in a reference value data storage apparatus 120, for example the curve 204 shown in solid line represents in presentation graphs 8, also keep the data of the temperature characterisitic of the drg work-hours being represented by dot-dash curve 202.A reference value correcting device 724 for example receives the temperature information of drg 110 via a reference value determination device 118.The temperature information of the drg 110 of a reference value correcting device 724 based on receiving and be stored in the temperature characterisitic data of drg work-hours of a reference value data storage apparatus 120, determines the drg work-hours corresponding with the temperature of drg 110.The value that is stored in the drg work-hours of a reference value data storage apparatus 120 and the brake temperature To of a reference value is respectively δ and δ '.In the following description, a reference value correcting device 724 is determined δ as drg work-hours.In addition,, as a simple example, suppose that brake temperature is the situation of To.In this situation, a reference value correcting device 724 receives the drg work-hours of instrumentation from drg abnormal detector 122.Drg work-hours by drg abnormal detector 122 instrumentations is made as η.In the time receiving the drg work-hours of instrumentation, a reference value correcting device 724 calculate the drg work-hours η of actual instrumentation and the drg work-hours δ that reads from a reference value data storage apparatus 120 between to depart from be correction Δ t=η-δ.The correction Δ t calculating is delivered to a reference value determination device 118 by a reference value correcting device 724.A reference value determination device 118 is by the temperature information of the drg based on exporting from temperature-detecting device 116 110 and to be stored in the value that the definite a reference value δ ' of a reference value data a reference value data storage apparatus 120 adds that the correction Δ t that transmits from a reference value correcting device 724 obtains be that δ '+Δ t determines as a reference value.In addition, the Data Representation method shown in Fig. 8 is same with the Data Representation method shown in Fig. 2, clearly also the temperature characterisitic of drg work-hours and a reference value can be represented with the step function shown in Fig. 3.
According to this embodiment, in the time that actual drg work-hours changes with respect to the drg work-hours of preserving in advance, by revising a reference value, can and the dish of the rheological parameters' change with time of drg or the pad of drg and towing machine or drum between the suitable work of carrying out adaptably drg such as gap variation monitor.
In one embodiment, also can use correction Δ t, by the data correction of the temperature characterisitic of the drg work-hours being represented by dot-dash curve 202 be as shown in dashed curve 802, be heavy line curve 804 by the temperature dependent a reference value data correction that represents a reference value shown in fine line curve 204, be kept at a reference value data storage apparatus 120 as new data.
In another embodiment, a reference value correcting device 724 transmits correction Δ t to drg abnormal detector 122.Drg abnormal detector 122 judges whether the correction Δ t transmitting has exceeded predetermined value Δ τ.In the situation that correction Δ t has exceeded predetermined value Δ τ, drg abnormal detector 122 is judged to be drg operation irregularity, and output stops the instruction of travelling of car 102.By such work, can prevent from existing on drg operating characteristic in the case of being stored in advance a reference value data storage apparatus 120 and actual drg work-hours departing from more greatly, occur, depart from respect to arriving at layer because drg delays in work makes car 102, so-called prominent on or prominent under.
As mentioned above, carried out the explanation as the schematic configuration example of the elevator brake abnormality detection system of an example of the present invention with reference to Fig. 7.A reference value correcting device 724 shown in Fig. 1 also can be installed by so-called embedded system, and this embedded system comprises hardware resource and the needed softwares of a reference value correction such as microcomputer, ROM, RAM or magnetic memory apparatus.In addition, in Fig. 7, as the mode separating with elevator control gear 112, a reference value correcting device 724 is shown, but also can be built in elevator control gear.
Below with reference to an example of the work of flowchart text the 3rd embodiment.Shown in Fig. 9 for the diagram of circuit of an example of work of the 3rd embodiment is described.To the work mark identical with work in diagram of circuit as shown in Figure 4 and Fig. 4 with reference to label identical with reference to label.The work of S402, S404, S406, S408 is identical with content illustrated in fig. 4, enters S914 when the processing of instrumentation drg work-hours η finishes in S408.
