Description
本發明係一種具有專利申請範圍獨立項之前言部分的測量裝置，此種測量裝置係用於具有至少一個升降廂的升降機。此外，本發明還包括具有此種裝置之升降機。The present invention is a measuring device having the preamble of the independent scope of the patent application, the measuring device being used for an elevator having at least one elevator car. Furthermore, the invention also includes an elevator having such a device.
升降機的升降廂通常都有配置專用的驅動裝置及剎車系統。整個升降機的電子控制主要是防止個別升降廂與被設置在運行路徑的固定位置(例如運行路徑終端)上的障礙物發生碰撞，或是與相鄰的升降廂發生碰撞。所謂運行路徑通常是由豎井所定義，運行路徑終端則是由豎井終端所定義。除此之外，運行路徑也可以是由框架結構、箱型結構、或是其他的結構所定義。此處所謂的運行路徑包括升降廂直接使用的空間及與其毗鄰的空間，例如被豎井圍住的空間。當升降廂緊急停住或是因抵達樓層而正常停住時，並無法確保於同一個運行路徑上，在這個升降廂上方或下方的另外一個升降機在任何情況下都可以及時停住，以免發生碰撞。一種可以避免升降廂碰撞的方法是控制成使升降機彼此相距足夠的距離，以及使升降機必須以規定的垂直速度移動。但是這樣的規定會導致升降機無法充分發揮其輸送能力，因而對升降機的成本與效益關係造成不利的影響。The lift compartment of the lift usually has a dedicated drive and brake system. The electronic control of the entire elevator is mainly to prevent the individual elevator cars from colliding with obstacles placed at fixed positions (such as the operation path terminals) of the operation path or with adjacent elevator cars. The so-called running path is usually defined by the shaft, and the running path terminal is defined by the shaft terminal. In addition to this, the running path can also be defined by a frame structure, a box structure, or other structure. The so-called operating path here includes the space directly used by the elevator car and the space adjacent thereto, such as the space enclosed by the shaft. When the elevator car is parked urgently or stopped normally due to the arrival of the floor, it cannot be ensured on the same running path. Another elevator above or below the elevator car can be stopped in any situation in time to avoid accidents. collision. One way to avoid collisions of the elevator car is to control the elevators at a sufficient distance from each other and to move the elevators at a prescribed vertical velocity. However, such regulations can cause the lift to fail to fully utilize its transport capacity, thus adversely affecting the cost and benefit relationship of the lift.
歐洲專利EP 769 469 B1揭示一種具有切斷升降廂之安全電路的器具的升降機，當一個升降廂與另外一個升降廂靠的太近時，這個器具就會將升降廂的安全電路切斷。根據這個專利，每一個升降廂都具有安全模組，其作用是計算升降廂的位置及速度，以便在必要時也可以啟動其他升降廂的剎車程序。每一個安全模組都必須持續測量同一個運行路徑中的其他升降廂的位置及速度，以便在緊急狀況時作出正確的反應。為此需要在緊急情況時能夠發出停機指令的決定模組。European Patent No. 769 469 B1 discloses an elevator having an appliance for cutting off the safety circuit of the elevator car. When one of the elevator cars is too close to the other elevator car, the appliance cuts off the safety circuit of the elevator car. According to this patent, each of the elevators has a safety module that functions to calculate the position and speed of the elevator car so that the brakes of the other elevators can be activated if necessary. Each safety module must continuously measure the position and speed of other elevators in the same operating path to respond correctly in an emergency. For this purpose, a decision module that can issue a shutdown command in an emergency situation is required.
國際專利WO 2004/043841 A1也提出一種類似的解決方案。這個專利提出的方法是在每一個升降廂上裝設紅外線、雷射、或超音波傳感器，其作用是測量其所屬之升降廂與在上方及下方之相鄰升降廂之間的距離。此外還建議設置運行路徑資訊系統或豎井資訊系統，以便使被設置在運行路徑範圍內的升降廂傳感器的測量導線板能夠以光柵形式被掃描到。這種光電組件可以控制升降廂與其他升降廂及運行路徑終端(例如豎井頂端及豎井底端)的距離，以及在必要時採取必要的控制手段，以防止發生碰撞。A similar solution is also proposed in the international patent WO 2004/043841 A1. The method proposed in this patent is to install an infrared, laser, or ultrasonic sensor on each of the lift boxes, the function of which is to measure the distance between the elevator car to which it belongs and the adjacent lift cars above and below. It is also proposed to provide a running path information system or a shaft information system so that the measuring conductors of the elevator car sensors arranged within the operating path range can be scanned in raster form. This optoelectronic component controls the distance between the elevator car and other elevators and the end of the run path (such as the top of the shaft and the bottom of the shaft) and, if necessary, the necessary controls to prevent collisions.
國際專利WO 2004/043841 A1的方法是一種很複雜的解決方案，因為不同升降廂的光電組件之間必須一直保持溝通，才能確定升降廂在任何一刻的位置及速度。The method of the international patent WO 2004/043841 A1 is a very complicated solution, since the communication between the optoelectronic components of the different elevator cars must always be maintained in order to determine the position and speed of the elevator car at any moment.
此外，由於以上提及的解決方案的所有系統都必須彼此配合，因此運轉方式都很複雜。而且由於系統很複雜，因此也容易發生故障。In addition, since all the systems of the above mentioned solutions must cooperate with each other, the operation is complicated. And because the system is very complicated, it is also prone to failure.
本發明的目的是提出一種運轉方式比現有之技術更為簡單的升降機。It is an object of the present invention to provide an elevator that operates in a manner that is simpler than prior art.
採用具有本發明之申請專利範圍獨立項之特徵的測量裝置即可達到上述目的。申請專利範圍附屬項之內容為本發明之各種有利的實施方式。The above object can be attained by a measuring device having the features of the independent item of the scope of the patent application of the present invention. The content of the patent application scope is a matter of various advantageous embodiments of the invention.
本發明是同樣適合用於防止兩個彼此相當靠近的升降廂發生碰撞，以及防止升降廂與運行路徑終端發生碰撞。以下將說明本發明之升降機測量裝置的各種實施方式。The present invention is equally suitable for preventing collisions between two elevator cars that are relatively close to each other and for preventing collision of the elevator car with the end of the running path. Various embodiments of the elevator measuring device of the present invention will be described below.
根據第一種實施方式，升降機(具有至少一個可以沿著升降機的運行路徑移動的升降廂)的測量裝置具有至少一個發送器及至少一個接收器。其中接收器係被設置在該升降廂上，而發送器則是被設置在運行路徑上，及/或發送器係被設置在升降廂上，而接收器則是被設置在運行路徑上。發送器會發出一道與運行方向夾第一角度的射線。第一角度係預定成當升降廂接近相對於運行路徑而言位置固定的障礙物時，依給定的第一角度將射線射入接收器。According to a first embodiment, the measuring device of the elevator (having at least one elevator car movable along the operating path of the elevator) has at least one transmitter and at least one receiver. The receiver is disposed on the elevator car, and the transmitter is disposed on the running path, and/or the transmitter is disposed on the elevator car, and the receiver is disposed on the running path. The transmitter emits a beam of light at a first angle to the direction of travel. The first angle is predetermined to inject radiation into the receiver at a given first angle when the elevator car approaches an obstacle fixed in position relative to the travel path.
第一種實施方式的測量裝置也可以有其餘配置。例如可以將發送器設置在運行路徑上，以及將接收器設置在第一升降廂上。第二對發送器及接收器則是以相反的方式設置，也就是將發送器設置在升降廂上，以及將接收器設置在運行路徑上。測量裝置的另外一種配置是將兩個發送器設置在運行路徑上，以及將兩個接收器設置在升降廂上。The measuring device of the first embodiment may also have the remaining configuration. For example, the transmitter can be placed on the travel path and the receiver can be placed on the first lift car. The second pair of transmitters and receivers are arranged in the opposite manner, that is, the transmitter is placed on the elevator car and the receiver is placed on the travel path. Another configuration of the measuring device is to place two transmitters on the travel path and two receivers on the lift car.
根據第二種實施方式，升降機(具有至少一個可以沿著升降機的運行路徑移動的升降廂)的測量裝置具有至少一個發送器及至少一個接收器。其中接收器及發送器係被設置在升降廂上，及/或接收器及發送器係被設置在運行路徑上。發送器會發出一道與運行方向夾第一角度的射線。第一角度係預定成當升降廂接近相鄰的升降廂或相對於運行路徑而言位置固定的障礙物時，射線射入接收器。According to a second embodiment, the measuring device of the elevator (having at least one elevator car that can be moved along the operating path of the elevator) has at least one transmitter and at least one receiver. The receiver and the transmitter are disposed on the elevator car, and/or the receiver and the transmitter are disposed on the operation path. The transmitter emits a beam of light at a first angle to the direction of travel. The first angle is predetermined such that when the elevator car approaches an adjacent elevator car or an obstacle fixed in position relative to the travel path, the radiation is incident on the receiver.
第二種實施方式的測量裝置最好是具有至少一個反射器，其作用是將發送器發出的射線反射到接收器。如果發送器及接收器都是被設置在運行路徑上，則應將反射器設置在升降廂上。反之，如果發送器及接收器都是被設置在升降廂運行路徑上，則應將反射器設置在運行路徑上。第二種實施方式的測量裝置也可以有其餘配置。例如可以在升降廂上及運行路徑上各設置一對發送器及接收器。測量裝置的另外一種配置是將兩個發送器及兩個接收器設置在升降廂或運行路徑上。The measuring device of the second embodiment preferably has at least one reflector for reflecting the radiation emitted by the transmitter to the receiver. If the transmitter and receiver are both set in the run path, the reflector should be placed on the lift box. Conversely, if both the transmitter and the receiver are placed in the elevator car travel path, the reflector should be placed on the run path. The measuring device of the second embodiment can also have the rest of the configuration. For example, a pair of transmitters and receivers can be provided on the elevator car and on the operating path. Another configuration of the measuring device is to place two transmitters and two receivers in the elevator car or in the running path.
根據第三種實施方式，升降機(具有至少一個可以沿著升降機的運行路徑移動的升降廂)的測量裝置具有至少一個發送器及至少一個接收器。其中接收器係被設置在第一升降廂上，而發送器則是被設置在第二升降廂上。發送器會發出一道與運行方向夾第一角度的射線。第一角度係預定成當升降廂接近相對於運行路徑而言位置固定的障礙物時，射線射入接收器。According to a third embodiment, the measuring device of the elevator (having at least one elevator car movable along the operating path of the elevator) has at least one transmitter and at least one receiver. The receiver is disposed on the first lift box and the transmitter is disposed on the second lift box. The transmitter emits a beam of light at a first angle to the direction of travel. The first angle is predetermined such that when the elevator car approaches an obstacle fixed in position relative to the travel path, the radiation is incident on the receiver.
第三種實施方式的測量裝置也可以有其餘配置。例如可配置額外的發送器及接收器，因而使第一升降廂上有兩個發送器，以及第二升降廂上有兩個接收器，或是使第一升降廂及第二升降廂上各有一個發送器及一個接收器。The measuring device of the third embodiment may have other configurations as well. For example, an additional transmitter and receiver can be configured so that there are two transmitters on the first lift box and two receivers on the second lift box, or each of the first lift compartment and the second lift compartment There is a transmitter and a receiver.
在知道上述各種實施方式後，熟習該項技術者即可在一個升降機上實現所有的實施方式。在這種情況下，這三種實施方式的測量裝置均具有一個或多個反射器，這一個或多個反射器係被設置在一個升降廂及/或運行路徑上，其作用是將來自發送器的入射射線反射到接收器。Having known the various embodiments described above, one skilled in the art can implement all embodiments on one elevator. In this case, the measuring devices of the three embodiments each have one or more reflectors, which are arranged in a lifting car and/or a running path, which function to be from the transmitter The incident ray is reflected to the receiver.
在以上三種實施方式中，發送器都會發射一道可以被相應之接收器偵測到的射線。在操作一個或多個升降廂時，這一對發送器及接收器(有時還加上一個或多個反射器)在運行路徑及升降廂範圍的設置方式會使發送器發出的射線在接收器及/或一個反射器上產生移動的測量點。這個接收器及/或反射器定義關於隨時間或位置變化的反應區，在這個反應區內可以引發適當的反應。例如可以利用這個反應區補償系統反應時間或豎井設備的容許誤差。In the above three embodiments, the transmitter transmits a ray that can be detected by the corresponding receiver. When operating one or more elevators, the pair of transmitters and receivers (and sometimes one or more reflectors) are placed in the path of the travel path and the range of the lifts to cause the transmitter to emit radiation A moving measuring point is generated on the device and/or on a reflector. This receiver and/or reflector defines a reaction zone that varies with time or position within which an appropriate reaction can be initiated. For example, this reaction zone can be utilized to compensate for system reaction time or tolerances of the shaft equipment.
為了偵測射線，接收器具有傳感器區，該傳感器區具有一個或多個敏感的傳感器區。如果傳感器區分成多個子區，這些子區最好是可以分開個別計值。因此接收器最好是具有計值系統，以便能夠依據射線照射到的子區引發適當的反應。In order to detect radiation, the receiver has a sensor zone with one or more sensitive sensor zones. If the sensor is divided into multiple sub-areas, these sub-areas are preferably individually separable. Therefore, the receiver preferably has a metering system to enable an appropriate reaction to be initiated depending on the sub-area to which the radiation is directed.
這個傳感器區最好是被垂直設置在升降廂上或運行路徑上，這樣做的好處可以減少沉積在傳感器區上的灰塵。為了進一步減少沉積在傳感器區的灰塵，可以使傳感器區與垂直方向夾一個角度，也就是說可以使敏感的傳感器面向下傾斜0度至90度。這種實施方式特別適於測量裝置具有反射器的情況。This sensor zone is preferably placed vertically on the lift car or in the path of travel, which has the benefit of reducing dust deposits on the sensor area. In order to further reduce the dust deposited in the sensor area, the sensor area can be angled with the vertical direction, that is, the sensitive sensor can be tilted downward by 0 to 90 degrees. This embodiment is particularly suitable for the case where the measuring device has a reflector.
可以利用不同的物理原理使發送器產生射線。所產生的射線可以是電磁波、電波、磁波、聲波、或光波。接收器的傳感器區接收的射線是依所選擇的實施方式決定。最好是選擇發送及接收紅外線、雷射、或超音波的發送器及接收器。The transmitter can be used to generate radiation using different physical principles. The generated rays may be electromagnetic waves, electric waves, magnetic waves, sound waves, or light waves. The radiation received by the sensor area of the receiver is determined by the chosen implementation. It is best to choose a transmitter and receiver that sends and receives infrared, laser, or ultrasonic waves.
可以透過一個或多個參數隨時間可變地設定射線及運行方向之間的角度。可以選擇升降廂的位置、速度或加速度作為參數、或是選擇升降廂與基準點的距離、相對速度及/或相對加速度作為參數、及/或選擇升降機的工作狀態作為參數。The angle between the ray and the direction of travel can be variably set over time by one or more parameters. The position, speed or acceleration of the elevator car can be selected as a parameter, or the distance between the elevator car and the reference point, the relative speed and/or the relative acceleration as parameters, and/or the operating state of the elevator can be selected as parameters.
根據本發明之測量裝置的另外一種實施方式，接收器具有分成多個子區的傳感器區。由於每一個子區都可以分開個別計值，因此只要傳感器位於移動的測量點的範圍內，傳感器就可以計算出升降廂的位置。在相應的傳感器區長度及/或傳感器的定位、接收器的定位及/或反射器的定位、及/或角度調整的定位的情況下，測量裝置也可以作為絕對位置測量裝置。According to a further embodiment of the measuring device according to the invention, the receiver has a sensor zone divided into a plurality of sub-zones. Since each sub-zone can be individually counted separately, the sensor can calculate the position of the elevator car as long as the sensor is within the range of the moving measurement point. In the case of a corresponding sensor zone length and/or positioning of the sensor, positioning of the receiver and/or positioning of the reflector, and/or angular adjustment, the measuring device can also be used as an absolute position measuring device.
本發明的一個優點是只需使用市面上常見的元件就可以製造出能夠控制距離或控制距離及速度的測量裝置，及/或製造出可以測定升降廂與運行路徑之相對位置的測量裝置。另外一個優點是可以經由接收器自動測定距離，以及在升降廂太過靠近運行路徑終端或相鄰的升降廂時引發自主反應。此外，接收器與區域性計算單元可以根據接收到的速度資料合作阻止發生碰撞的反應。此外，測量裝置的其餘配置可以提供額外的安全性，以及使升降廂能夠做出自主及快速的反應，以防止發生碰撞。An advantage of the present invention is that a measuring device capable of controlling the distance or controlling the distance and speed can be manufactured using only components that are common on the market, and/or measuring devices that can determine the relative position of the elevator car to the operating path. Another advantage is that the distance can be automatically determined via the receiver and an autonomous reaction can be initiated when the elevator car is too close to the end of the running path or the adjacent elevator car. In addition, the receiver and the regional computing unit can cooperate to prevent the collision from reacting based on the received velocity data. In addition, the remaining configuration of the measuring device provides additional safety and enables the elevator car to react autonomously and quickly to prevent collisions.
以下配合圖式及實施例對本發明的內容作進一步的說明。The contents of the present invention will be further described below in conjunction with the drawings and embodiments.
升降機通常具有至少一個由牽引手段懸吊住的升降廂。為了平衡升降廂的重量，升降機最好是具有一個也是以牽引手段吊住的平衡配重。升降機具有驅動升降廂用的驅動裝置，該驅動裝置具有驅動皮帶輪及馬達以及止動剎車器(選擇性配備)。其中驅動皮帶輪及牽引手段處於有效接觸狀態。驅動皮帶輪及馬達通常是經由軸及/或傳動機構彼此連接，因此馬達可以經由驅動皮帶輪及牽引手段操作升降廂。The elevator typically has at least one lift car suspended by a towing means. In order to balance the weight of the elevator car, the elevator preferably has a balance weight that is also suspended by traction. The elevator has a drive for driving the lift car, the drive has a drive pulley and a motor and a stop brake (optional). The drive pulley and the traction means are in an effective contact state. The drive pulleys and motors are typically connected to one another via shafts and/or transmissions so that the motor can operate the elevator car via drive pulleys and traction means.
升降廂能夠通過的空間是由運行路徑所預定。運行路徑的範圍包括升降廂直接需要的空間及其相鄰空間。在大多數的情況下，運行路徑定義的空間是指被一個升降機豎井圍住的空間。因此在本發明中，可以將運行路徑及升降機豎井視為同義詞。升降機豎井是由四個豎井壁、一個豎井蓋、以及一個豎井底所定義。所謂豎井終端是指一個包含豎井蓋或豎井及其相鄰之上方或下方部分的區域。The space through which the lift car can pass is predetermined by the running path. The range of the running path includes the space directly required by the elevator car and its adjacent space. In most cases, the space defined by the run path refers to the space enclosed by an elevator shaft. Therefore, in the present invention, the running path and the elevator shaft can be regarded as synonyms. The elevator shaft is defined by four shaft walls, a shaft cover, and a shaft bottom. By silo terminal is meant an area containing a shaft cover or shaft and its adjacent upper or lower portions.
測量裝置具有至少一個發送器及相應的接收器。發送器會發出能夠由接收器接收的射線。接收器可以依據接收到的射線直接引發反應，或是與連接的控制單元共同引發反應。測量裝置也可以具有反射器(選擇性配備)。反射器的作用是將發送器發出的射線直接反射到接收器，或是經由一個或多個反射器反射到接收器。在以上的實施例中，發送器最好是能夠發出具可見光或不可見光之波長範圍的光束的光源。與此相應的，接收器具有能夠接收光束的光敏傳感器區。The measuring device has at least one transmitter and a corresponding receiver. The transmitter emits rays that can be received by the receiver. The receiver can directly initiate a reaction based on the received radiation or initiate a reaction with the connected control unit. The measuring device can also have a reflector (optional). The function of the reflector is to reflect the radiation emitted by the transmitter directly to the receiver or to the receiver via one or more reflectors. In the above embodiments, the transmitter is preferably a light source capable of emitting a light beam having a wavelength range of visible or invisible light. Correspondingly, the receiver has a photosensitive sensor area capable of receiving a light beam.
第1A圖及第1B圖分別顯示本發明的第一種實施方式之在兩個不同的時間點的瞬時攝影。根據這第一種實施方式，升降機(10)具有上方升降廂(A1)及下方升降廂(A2)，這兩個升降廂可以在升降機(10)的共同的運行路徑(11)上沿著運行方向(z)獨立地移動，例如運行路徑(11)可以是升降機豎井(11)。為了使升降廂(A1，A2)可以沿著運行路徑(11)獨立地移動，可以為升降廂(A1，A2)分別配備驅動裝置及止動剎車器，或是升降廂(A1，A2)可以與中央驅動系統耦合。除此之外也有其他的方法能夠讓升降機的升降廂可以各自沿著運行路徑(11)移動。升降廂也可以是在水平方向運行路徑或其他方向的運行路徑上移動。Figs. 1A and 1B show instantaneous photographing at two different time points, respectively, of the first embodiment of the present invention. According to this first embodiment, the elevator (10) has an upper elevator car (A1) and a lower elevator car (A2), which can be operated along a common running path (11) of the elevator (10) The direction (z) moves independently, for example the operating path (11) may be an elevator shaft (11). In order to enable the elevator car (A1, A2) to move independently along the running path (11), the lifting device (A1, A2) can be equipped with a driving device and a stop brake, respectively, or the elevator car (A1, A2) can be Coupling with the central drive system. In addition to this, there are other ways in which the elevator car of the elevator can be moved along the running path (11). The elevator car can also be moved on a running path in a horizontal direction or in other directions.
例如可以用第一光電測量裝置(20)作為測量裝置。該光電測量裝置(20)具有第一發送器，例如以被設置在上方升降廂(A1)底部的光源(21)作為發送器，如第1A圖及第1B圖所示。例如可以用能夠發出光束的發光二極體作為光源。更好的方式是以雷射二極體或固體雷射作為光源。For example, the first photo-electric measuring device (20) can be used as the measuring device. The photo-electric measuring device (20) has a first transmitter, for example, a light source (21) disposed at the bottom of the upper elevator car (A1) as a transmitter, as shown in FIGS. 1A and 1B. For example, a light-emitting diode capable of emitting a light beam can be used as the light source. A better way is to use a laser diode or a solid laser as the light source.
此外，測量裝置(20)還具有第一接收器(22)。第一接收器(22)在下方升降廂(A2)的底部有光敏的第一傳感器區(22)。光電二極體、光電電晶體、或是其他的光敏元件均可作為傳感器區(22)。Furthermore, the measuring device (20) also has a first receiver (22). The first receiver (22) has a photosensitive first sensor zone (22) at the bottom of the lower elevator car (A2). A photodiode, a phototransistor, or other photosensitive element can be used as the sensor area (22).
第一光源(21)會發出一道與運行方向(z)夾第一角度(W1)的光束(L1)。在此種實施方式中，光束(L1)的方向是向下。The first light source (21) emits a light beam (L1) at a first angle (W1) to the running direction (z). In such an embodiment, the direction of the beam (L1) is downward.
第1A圖顯示瞬時攝影(此時升降廂之間的距離為S1)，此時上方升降廂(A1)以速度(v1)向下移動，下方升降廂(A2)則靜止不動(v2=0)。此時光束(L1)會照射在升降機豎井(11)內下方升降廂(A2)上方的內壁的某一個位置。Figure 1A shows the instantaneous photography (the distance between the elevator cars is S1), at which time the upper elevator car (A1) moves downwards at speed (v1) and the lower elevator car (A2) stands still (v2=0). . At this time, the light beam (L1) is irradiated to a certain position on the inner wall above the lower lift box (A2) in the elevator shaft (11).
如第1B圖所示，當兩個升降廂(A1，A2)之間的相對距離縮短到最短距離(S2)，光束(L1)就會首度照射到接收器的傳感器區(22)。As shown in Fig. 1B, when the relative distance between the two elevator cars (A1, A2) is shortened to the shortest distance (S2), the light beam (L1) is first irradiated to the sensor area (22) of the receiver.
根據本發明，第一角度(W1)應設定或調整到當上方及下方升降廂(A1，A2)之間的距離縮短到最短距離(S2)時，第一光束(L1)會照射到第一傳感器區(22)。在光束(L1)會照射到傳感器區(22)的瞬間，第一接收器(22，24)會偵測到光束(L1)，並引發反應(R1)，然後經由管線或線路(23)將這個反應傳送到控制單元。According to the invention, the first angle (W1) should be set or adjusted such that when the distance between the upper and lower lift boxes (A1, A2) is shortened to the shortest distance (S2), the first light beam (L1) is illuminated to the first Sensor area (22). At the instant when the beam (L1) will illuminate the sensor area (22), the first receiver (22, 24) will detect the beam (L1) and initiate a reaction (R1), which will then be via a line or line (23). This reaction is transmitted to the control unit.
本發明允許測量裝置可以有不同的實施方式或構造。The invention allows the measuring device to have different embodiments or configurations.
最簡單的實施方式是在光束(L1)首度照射到傳感器區(22)時，立刻直接引發反應。在這種情況下，傳感器區(22)的面積只到大到即使升降廂在升降機(10)內略有晃動，接收器(22，24)仍然能夠確實偵測到光束(L1)的程度即可。The simplest embodiment is to directly initiate the reaction as soon as the beam (L1) is first illuminated into the sensor zone (22). In this case, the area of the sensor zone (22) is only so large that even if the elevator car is slightly shaken in the elevator (10), the receiver (22, 24) can still detect the extent of the beam (L1). can.
第2圖顯示本發明的另外一種實施方式。第2圖顯示的是光束(L1)首度被傳感器區(22)的光敏的子區(22.1)偵測到之後一小段時間的瞬時攝影。Figure 2 shows another embodiment of the invention. Figure 2 shows the instant photography of the beam (L1) for the first time after being detected by the photosensitive sub-region (22.1) of the sensor area (22).
每個子區最好都可以分開個別計值，也就是說每一個子區都有電連接部。本發明的不同的實施方式最好是都有適當的計值系統24，(第3圖的實施方式是24及28)，以便能夠依據第一光束(L1)到達的子區(22.1-22.n)引發適當的反應(R1，R2，R3，R4)。Each sub-zone is preferably individually separable, that is to say each sub-zone has an electrical connection. Preferably, different embodiments of the present invention have appropriate evaluation systems 24 (embodiments 24 and 28 in Fig. 3) to enable sub-regions to be reached in accordance with the first beam (L1) (22.1-22. n) Initiating an appropriate reaction (R1, R2, R3, R4).
如果以第1A圖及第1B圖的距離為準，則在第2圖中顯示之瞬間的距離已經小於S2。If the distance between FIG. 1A and FIG. 1B is taken as the standard, the distance at the instant shown in FIG. 2 is already smaller than S2.
由於上方升降廂(A1)繼續以速度(v1)向下方升降廂(A2)移動，因此光束(L1)產生的「光點」會向左移動。在這種實施方式中可以將測量裝置設計、程式化、或是調整成當傳感器區(22)的子區(22.1)首度被光束照射到時會做出預警反應，或是將升降機(10)(更確切的說是升降廂(A1)及/或升降廂(A2))轉換成預警模式。當光點越過事先給定的傳感器區(22)的子區(22.4)，將會引發最終反應(例如經由啟動剎車裝置或上方升降廂(A1)及/或下方升降廂(A2)的制動剎車，使升降廂緊急停住)。這種兩段式反應可以提供進一步的安全性，以及協助避免錯誤的反應引發。Since the upper lift box (A1) continues to move toward the lower lift box (A2) at the speed (v1), the "light spot" generated by the light beam (L1) moves to the left. In this embodiment, the measuring device can be designed, programmed, or adjusted to provide an early warning response when the sub-zone (22.1) of the sensor zone (22) is first illuminated by the beam, or to lift the elevator (10) (more precisely, the lift box (A1) and/or the lift box (A2)) is converted into an early warning mode. When the spot passes over a sub-zone (22.4) of the sensor zone (22) given in advance, the final reaction will be triggered (for example via the brakes of the starting brake or the upper lift (A1) and/or the lower lift (A2)). To make the lift car emergency stop). This two-stage reaction provides further safety and helps to avoid false reaction initiation.
接著根據第2圖說明本發明的另外一種實施方式。如傳感器區(22)下方的箭頭所示，當升降廂(A1，A2)之間的距離以速度(v1)縮小時，光點會以速度(v1*)向左移動。利用簡單的三角函數即可由速度(v1*)計算出速度(v1)。例如，如果角度(W1)為45度，由於tan45=1，因此v1=v1*。如果角度(W1)大於45度，則v1*大於v1。如果角度(W1)小於45度，則v1*小於v1，也就是說可以達到減速或變慢的效果。經由這樣的減速可以縮小傳感器區(22)的面積，由於傳感器的價格相當昂貴，因此這是一個優點。Next, another embodiment of the present invention will be described based on Fig. 2 . As indicated by the arrow below the sensor zone (22), when the distance between the elevator cars (A1, A2) is reduced by the speed (v1), the spot moves to the left at a speed (v1*). The velocity (v1) can be calculated from the velocity (v1*) using a simple trigonometric function. For example, if the angle (W1) is 45 degrees, since tan45=1, v1=v1*. If the angle (W1) is greater than 45 degrees, then v1* is greater than v1. If the angle (W1) is less than 45 degrees, then v1* is less than v1, which means that the effect of slowing down or slowing down can be achieved. The area of the sensor area (22) can be reduced by such deceleration, which is an advantage since the price of the sensor is quite expensive.
第3圖顯示另外一種實施方式。由於這種施方式能夠提供最大的安全性，因此就目前而言這種實施方式是最好的。如第3圖所示，這種實施方式使用兩個光電測量裝置。其中第一個測量裝置的配置方式和前面所述的測量裝置相同，第二個測量裝置的構造可以是與第一個測量裝置相同，但是其位置則是在下方升降廂(A2)的頂部，也就是幾乎與第一個測量裝置的位置剛好是鏡反像的關係。第二個傳感器區(26)則位於升降廂(A1)的底部。Figure 3 shows another embodiment. Since this type of application provides maximum safety, this embodiment is currently the best. As shown in Figure 3, this embodiment uses two optoelectronic measuring devices. The first measuring device is configured in the same manner as the measuring device described above, and the second measuring device may be constructed in the same manner as the first measuring device, but the position is at the top of the lower lifting box (A2). That is, almost the position of the first measuring device is exactly the inverse of the mirror. The second sensor zone (26) is located at the bottom of the elevator car (A1).
在第3圖的實施方式中，兩個角度是一樣大的，也就是說W1=W2。但是這兩個角度也可以設定或調整成不一樣大。如果使用的是兩個相同的光電測量，且W1=W2，則兩個光電測量裝置會在相同的時間發出信號，或是在相同的時間引發反應(R3，R4)。In the embodiment of Figure 3, the two angles are the same, that is, W1 = W2. But these two angles can also be set or adjusted to be different. If two identical photoelectrons are used and W1 = W2, the two photo-electric measuring devices will signal at the same time or initiate the reaction at the same time (R3, R4).
在以上的圖式中都有顯示接收器引發反應的情況。反應的種類會隨著測量裝置的實施方式、程式設定、或是調整方式而有所不同。以上的圖式均顯示接收器能夠經由管線或其他的線路(23，27)發出信號或資訊。這些信號或資訊會在引發反應之前被處理，或是直接引發反應，例如切斷安全電路的開關。In the above figures, there are cases where the receiver initiates a reaction. The type of reaction will vary depending on the implementation of the measuring device, the programming, or the method of adjustment. The above figures all show that the receiver can signal or inform via lines or other lines (23, 27). These signals or information are processed before the reaction is triggered, or directly trigger a reaction, such as switching off the safety circuit.
有許多不同的方法可以用來引發反應。至於建議採用何種方法則應視升降機(10)的不同細節而定。例如，如果升降機(10)的每一個升降廂(A1，A2)都具有各自的安全電路，則可以經由上方及/或下方升降廂(A1，A2)之安全電路的接收器將升降廂停住。There are many different ways to trigger a reaction. The recommended method should be based on the different details of the lift (10). For example, if each of the elevators (A1, A2) of the elevator (10) has its own safety circuit, the elevator can be stopped via the receiver of the safety circuit above and/or below the elevator car (A1, A2). .
升降機(10)的每一個升降廂(A1，A2)最好都具有各自的安全電路，在這個安全電路中有多個安全元件(例如安全接點及安全開關)串聯在一起。只有當安全電路及其所有安全接點都接通時，相應的升降廂(A1)或升降廂(A2)才可以移動。安全電路與升降機(10)的驅動裝置或剎車單元連接，以便在必要時將相應的升降廂(A1)或升降廂(A2)停住。Preferably, each of the elevators (A1, A2) of the elevator (10) has its own safety circuit in which a plurality of safety elements (e.g., safety contacts and safety switches) are connected in series. The corresponding lift (A1) or lift (A2) can only be moved when the safety circuit and all its safety contacts are switched on. The safety circuit is connected to the drive or brake unit of the elevator (10) to stop the corresponding lift (A1) or lift (A2) if necessary.
本發明的測量裝置亦可應用於以安全總線系統取代上述之安全電路的升降機。The measuring device of the present invention can also be applied to an elevator that replaces the above-described safety circuit with a safety bus system.
除了切斷安全電路外，也可以啟動升降廂(A1，A2)的剎車。In addition to cutting off the safety circuit, the brakes of the elevator car (A1, A2) can also be activated.
另外一種可能性是啟動升降廂(A1，A2)安全剎車。Another possibility is to activate the safety brakes of the lift (A1, A2).
因此可以視實施方式而定，由接收器(22，24；26，28)引發下列反應中的一個或多個反應：Thus, depending on the embodiment, one or more of the following reactions may be initiated by the receiver (22, 24; 26, 28):
--切斷至少一個升降廂(A1，A2)的安全電路；- cutting off the safety circuit of at least one of the elevator cars (A1, A2);
--發送信號到升降機控制單元；- send a signal to the elevator control unit;
--啟動至少一個升降廂(A1，A2)的剎車裝置；- starting the brake device of at least one lift car (A1, A2);
--啟動至少一個升降廂(A1，A2)的安全剎車；- start the safety brake of at least one lift car (A1, A2);
--將至少一個升降廂(A1，A2)轉換為預警狀態；- converting at least one lift car (A1, A2) into an early warning state;
--調整至少一個升降廂(A1，A2)的垂直速度(v1，v2)。- Adjust the vertical speed (v1, v2) of at least one of the elevator cars (A1, A2).
因此本發明可以實現距離控制，或是實現距離及速度控制。Therefore, the present invention can realize distance control or achieve distance and speed control.
以垂直方向(z)為準的角度(W1，W2)可以在0度至90度之間調整。角度(W1，W2)以介於0度至60度之間，或最好是介於10度至50度之間為較佳。The angle (W1, W2) in the vertical direction (z) can be adjusted between 0 and 90 degrees. The angle (W1, W2) is preferably between 0 and 60 degrees, or preferably between 10 and 50 degrees.
最好是以下列參數中的一個或多個參數隨時間調整角度(W1，W2)：升降廂(A1，A2)的位置、速度或加速度、升降廂(A1，A2)與基準點的距離、相對速度及/或相對加速度、升降機(10)的工作狀態。Preferably, the angle (W1, W2) is adjusted over time with one or more of the following parameters: position, velocity or acceleration of the elevator car (A1, A2), distance between the elevator car (A1, A2) and the reference point, Relative speed and / or relative acceleration, working state of the lift (10).
例如，當升降廂(A1，A2)的速度較大時，可以將角度(W1，W2)調小一些，以便光束(L1，L2)可以比較早照射到接收器(22，24)，這樣接收器(22，24)就可以比較早引發反應(R1，R2，R3，R4)。如果升降廂(A1，A2)的速度比較小，則需要早一點引發反應(R1，R2，R3，R4)的必要性就會相應的降低，因此可以將角度(W1，W2)調大一些。加速度與角度之間的關係也是如此。For example, when the speed of the elevator car (A1, A2) is large, the angle (W1, W2) can be adjusted smaller so that the light beam (L1, L2) can be irradiated to the receiver (22, 24) earlier, thus receiving The reactor (22, 24) can initiate the reaction earlier (R1, R2, R3, R4). If the speed of the elevator car (A1, A2) is relatively small, the necessity to initiate the reaction earlier (R1, R2, R3, R4) is correspondingly reduced, so the angle (W1, W2) can be increased. The same is true for the relationship between acceleration and angle.
升降機(10)的某些工作狀態(例如檢查或保養的狀態)經常會規定升降廂的最大速度必須調低。因此在啟動升降廂(A1，A2)以進行檢查時，由於此時升降廂(A1，A2)只能以較低的速度運行，所以光束(L1，L2)的角度(W1，W2)在升降廂(A1，A2)被轉換成檢查狀態後即被調大。Certain operating conditions of the elevator (10), such as the state of inspection or maintenance, often dictate that the maximum speed of the elevator car must be lowered. Therefore, when the elevator car (A1, A2) is started for inspection, since the elevator car (A1, A2) can only operate at a lower speed, the angles (W1, W2) of the light beams (L1, L2) are raised and lowered. The car (A1, A2) is turned up after being converted into the check state.
升降廂(A1，A2)的位置可以用來決定調整角度(W1，W2)的時間點。也就是說需要定義升降廂(A1，A2)之間或升降廂(A1，A2)與豎井終端的臨界距離。當實際距離小於臨界距離，就會開始調整角度(W1，W2)。The position of the elevator car (A1, A2) can be used to determine the point in time at which the angle (W1, W2) is adjusted. That is to say, it is necessary to define the critical distance between the elevator car (A1, A2) or the elevator car (A1, A2) and the shaft terminal. When the actual distance is less than the critical distance, the angle (W1, W2) will be adjusted.
如果有多個升降廂在同一個豎井(11)內移動，則也可以在這些升降廂之間設置測量裝置。If a plurality of elevator cars are moved within the same shaft (11), measuring devices can also be provided between the elevator cars.
根據本發明的第二種實施方式，升降機具有可以沿著升降機的運行路徑或升降機豎井移動的升降廂。為達到這個目的，應使用如同第一種實施方式的升降廂(A1)，例如配備驅動裝置及制動剎車的升降廂。例如可以用第一光電測量裝置作為測量裝置，該光電測量裝置具有第一發送器，例如以被設置在上方升降廂底部的光源作為發送器。According to a second embodiment of the invention, the elevator has a lift car that can be moved along the operating path of the elevator or the elevator shaft. To achieve this, a lift car (A1) like the first embodiment, such as a lift car equipped with a drive and brakes, should be used. For example, a first optoelectronic measuring device can be used as the measuring device, which has a first transmitter, for example with a light source arranged at the bottom of the upper car as a transmitter.
此外，測量裝置還具有第一接收器。第一接收器在運行路徑底端有光敏的第一傳感器區。第一光源會發出一道與運行方向夾第一角度的光束。在此種實施方式中，光束的方向是向下。Furthermore, the measuring device also has a first receiver. The first receiver has a photosensitive first sensor zone at the bottom of the run path. The first source emits a beam of light at a first angle to the direction of travel. In such an embodiment, the direction of the beam is downward.
一種變化方式是將光源及接收器的位置互換，也就是說接收器位於升降廂底部，光源位於豎井底端。此外，也可以將傳感器區設置在豎井頂端，以防止升降廂過於接近豎井頂端而造成危險。One variation is to interchange the position of the light source and the receiver, that is to say the receiver is located at the bottom of the elevator car and the light source is at the bottom of the shaft. In addition, it is also possible to arrange the sensor zone at the top of the shaft to prevent the elevator car from being too close to the top of the shaft and posing a hazard.
根據本發明的第三種實施方式，升降機具有可以沿著升降機的運行路徑或升降機豎井移動的升降廂。為達到這個目的，應使用如同第一種實施方式的升降廂，例如配備驅動裝置及制動剎車的升降廂。例如可以用第一光電測量裝置作為測量裝置，該光電測量裝置具有第一發送器，例如以被設置在豎井頂端的光源作為發送器。According to a third embodiment of the invention, the elevator has a lift car that can be moved along the operating path of the elevator or the elevator shaft. To achieve this, a lift car like the first embodiment, such as a lift car equipped with a drive and brakes, should be used. For example, a first optoelectronic measuring device can be used as the measuring device, the optoelectronic measuring device having a first transmitter, for example with a light source arranged at the top of the shaft as a transmitter.
此外，測量裝置還具有第一接收器。第一接收器在豎井頂端有與光源相距一段距離的光敏的第一傳感器區。第一光源會發出一道與運行方向夾第一角度的光束。Furthermore, the measuring device also has a first receiver. The first receiver has a photosensitive first sensor zone at a distance from the source at the top of the shaft. The first source emits a beam of light at a first angle to the direction of travel.
此外，測量裝置還具有反射器，該反射器係被設置在升降廂的頂部。反射器所選擇的位置要使升降廂接近豎井頂端時，光束會照射在反射器上，並從反射器被反射到接收器。反射器的面積及接收器之光敏的傳感器區的面積最好是彼此配合，這樣在升降廂接近豎井頂端的過程中，光束會通過整個傳感器區。在此種實施方式中，光束在光源及反射器之間的方向是向下，而在被反射後的方向則是向上(朝接收器的方向)。Furthermore, the measuring device also has a reflector which is arranged at the top of the elevator car. The reflector is chosen such that when the elevator car approaches the top of the shaft, the beam will illuminate the reflector and be reflected from the reflector to the receiver. Preferably, the area of the reflector and the area of the photosensitive sensor area of the receiver are matched to each other such that the beam passes through the entire sensor area as the lift box approaches the top end of the shaft. In such an embodiment, the direction of the beam between the source and the reflector is downward, and the direction after being reflected is upward (toward the direction of the receiver).
一種變化方式是將光源及接收器設置在升降廂的頂部，以及將反射器設置在豎井頂端。此外，也可以將測量裝置設置在豎井底端，以防止升降廂過於接近豎井底端而造成危險。One variation is to place the light source and receiver on top of the elevator car and the reflector on the top of the shaft. In addition, it is also possible to arrange the measuring device at the bottom end of the shaft to prevent the elevator car from being too close to the bottom end of the shaft to cause danger.
測量裝置的第二種及第三種實施方式的作用原理和其他的實施方式是一樣的。因此幾乎可以不受限制的將以上描述的各種變化方式組合在一起。The principle of action of the second and third embodiments of the measuring device is the same as in the other embodiments. Therefore, the various variations described above can be combined almost without limitation.
