Description

The present invention relates to an elevator remote monitoring support device that supports remote monitoring of an elevator.

Conventionally, there has been a remote monitoring system for elevators equipped with a server computer that monitors the status of each elevator from a remote location by communicating with a plurality of elevators. In such a remote monitoring system for elevators, the processing load on the elevators can be reduced by performing various processing related to the safe operation of the elevators, such as determining the status of the elevators and dispatching workers, on the server computer. Can be planned.

As a related technology, conventionally, for example, periodic communication is performed between an elevator controller (control panel) that stores information on a maintenance terminal that maintains and manages itself, and a maintenance server that is remotely located in the controller. By periodically updating the information of the maintenance terminal stored in the controller and enabling communication between the controller and the maintenance terminal carried by the maintenance staff when the maintenance server goes down, the maintenance server can perform the communication. There was a technology that made it possible to dispatch maintenance personnel even if it went down (see, for example, Patent Document 1 below).

Japanese Unexamined Patent Publication No. 2015-13730

However, for example, in the case of an old-type elevator that was not supposed to be remotely monitored at the time of installation, it is difficult to perform remote monitoring after the elevator is installed because the elevator does not have a communication function. There was a problem. Further, in this case, if a failure occurs in an elevator that does not support remote monitoring, there is a problem that the discovery of the failure is delayed or the response for resolving the failure is delayed.

In addition, in the conventional technique, when adding a communication function with a server computer to an elevator that does not have a communication function, the work becomes large and the construction period becomes long, and the period during which the elevator cannot be used becomes long. , There was a problem of inconvenience to elevator users.

In addition, even if the elevator is equipped with a communication function at the time of installation, communication with the server computer for remote monitoring of the elevator is often performed using a signal unique to each manufacturer of the elevator. Alternatively, it has been difficult for an independent maintenance management company independent of the elevator management company affiliated with the manufacturer (hereinafter, appropriately referred to as "manufacturer, etc.") to remotely monitor the elevator.

For this reason, conventionally, the cost (maintenance management cost) spent on maintenance management including remote monitoring of the elevator by the elevator management manager tends to be uniquely set by the manufacturer of each elevator, and the elevator management manager maintains it. There was a problem that it was difficult to reduce management costs.

Further, in the remote monitoring system of the elevator by the conventional technique including the above-mentioned Patent Document 1, the processing load for the safe operation of the elevator is concentrated on the server computer, so that a high-performance server computer is required, and the system can be constructed. There was a problem that maintenance was costly and the burden of maintenance was heavy.

The present invention provides an elevator remote monitoring support device that can easily and inexpensively realize an elevator that can ensure the safety and convenience of elevator users in order to solve the problems caused by the above-mentioned prior art. With the goal.

In order to solve the above-mentioned problems and achieve the object, the remote monitoring support device for the elevator according to the present invention is used for each of the plurality of components that output a signal according to the state of the elevator.

Hereinafter, preferred embodiments of the elevator remote monitoring support device according to the present invention will be described in detail with reference to the accompanying drawings.

(Example of elevator configuration)
First, an example of the configuration of the elevator to which the remote monitoring support device for the elevator according to the embodiment of the present invention is applied will be described. FIG. 1 is an explanatory diagram showing an example of the configuration of an elevator to which the remote monitoring support device for the elevator according to the embodiment of the present invention is applied. In FIG. 1, the elevator 100 can be realized by, for example, a rope type (traction type) elevator 100.

The elevator 100 is installed in a building such as a multi-story building. Each part of the elevator 100 is driven and controlled by the control panel 101. The control panel 101 is connected to each part of the elevator 100, and for example, the control panel 101 outputs a signal for each part of the elevator 100, that is, a so-called “downstream signal”. Further, the control panel 101 receives, for example, a signal to the control panel 101 from each unit included in the elevator 100, that is, a so-called “upstream signal”.

The elevator 100 is provided with a hoistway (not shown) that penetrates each floor in the building along the vertical direction. One hoistway is provided for each elevator 100. A basket (riding basket) 102 for carrying people and goods is provided in the hoistway. The baskets 102 are provided one by one in one elevator 100, that is, one hoistway, and move up and down along the direction of the hoistway, that is, the vertical direction. The basket 102 is supported by a basket frame (not shown), and moves up and down together with the frame.

A guide rail (not shown) is provided on the side surface of the hoistway to guide the elevating position of the basket 102 (cage frame). At the bottom of the hoistway, a shock absorber 103 is provided to cushion the impact when the basket 102 falls and collides with the bottom surface. The shock absorber 103 may be a spring-type shock absorber that softens the impact by utilizing the elastic force of the spring, or may be an oil-filled shock absorber that softens the shock by utilizing the hydraulic resistance. The shock absorber 103 may also be provided on the ceiling surface of the hoistway.

Doors 104a are provided at positions (landings) 104 corresponding to each floor in the hoistway. The door 104a provided at the landing 104 is locked by a device called an interlock or the like (not shown). The interlock engages with the opening / closing mechanism of the door 102a of the basket 102 to release the lock only when the motor for opening / closing the door 102a of the basket 102 is driven while the basket 102 has arrived at the stop floor. As a result, only the door 104a provided at the landing 104 on the floor where the basket 102 is located can be opened and closed in conjunction with each other.

An operation panel 105 is installed at each platform 104. The operation panel 105 is provided with a landing call button 105a, a display 105b for displaying the floor on which the basket 102 is located, and the like, respectively. Further, each of the operation panels 105 is provided with a control board 105c for the operation panel 105. Each operation panel 105 is connected to the control panel 101 via a control board 105c provided therein.

The basket 102 is connected to one end of the rope 106. The rope 106 is slidably hung on a pulley (not shown) and a hoist (traction machine) 107, and the other end thereof is connected to a counterweight 108. Specifically, the rope 106 can be realized by, for example, a steel wire.

The hoisting machine 107 in the rope-type elevator 100 is installed, for example, in a machine room provided at the top of the elevator 100. The hoisting machine 107 can be provided at the uppermost part of the elevator 100 regardless of the presence or absence of a machine room. Alternatively, when the elevator 100 is of a type without a machine room, the hoisting machine 107 may be provided at the lower part of the elevator 100.

The hoisting machine 107 is connected to the control panel 101 via an inverter, for example, and is driven and controlled by the control panel 101 so as to stop the rotation on the floor where the basket 102 is stopped. In the rope-type elevator 100, the basket 102 is moved up and down by using the frictional force (traction) between the rope 106 and the pulley generated by driving the hoist 107.

The hoisting machine 107 includes an encoder (not shown), and the control panel 101 can determine the rotation speed and the rotation position of the hoisting machine 107 based on the output signal from the encoder. As the encoder, for example, an absolute encoder may be used, or an incremental encoder may be used.

The bottom of the basket 102 is connected to the other end of a wire rope (or chain) for weight balance adjustment, one end of which is connected to the bottom of the counterweight 108 (not shown). As a result, for example, in an elevator 100 installed in a high-rise building, the weight balance between the basket 102 side and the counterweight 108 side is imbalanced in the vicinity of the top floor or the bottom floor due to the weight of the rope 106. Can be reliably prevented from slipping off the rope 106 from the sheave of the hoist 107.

Further, the elevator 100 includes an electromagnetic brake 109, a speed governor (governor machine) 110, a limit switch 111, and the like. The electromagnetic brake 109 includes a coil, is driven and controlled by a control panel 101, and uses an electromagnetic force generated by energizing the coil to stop the rotation of the hoisting machine 107. The electromagnetic brake 109 can hold the hoisting machine 107 in a stopped state.

The electromagnetic brake 109 stops the rotation of the hoisting machine 107 when the power supply is stopped due to a power failure or the like. Specifically, the electromagnetic brake 109 uses a non-excitation actuated electromagnetic brake 109 that operates by the force of a spring to stop the rotation of the hoisting machine 107 when the energization of the coil is cut off, for example, in the event of a power failure. be able to.

The governor 110 detects the overspeed of the basket 102. The speed governor 110 can be realized by, for example, a centrifugal speed governor including a governor rope 110a, a governor pulley 110b, a rotary weight (not shown) and the like. In such a speed governor 110, the governor rope 110a is interlocked with the operation of the basket 102. The governor pulley 110b rotates in conjunction with the operation of the governor rope 110a.

The rotary weight operates according to the rotation speed of the governor pulley 110b, that is, the magnitude of the centrifugal force caused by the rotation of the governor pulley 110b. Specifically, the rotary weight operates so as to open toward the outer peripheral side of the governor pulley 110b when the rotation speed of the governor pulley 110b is high, and closes to the inner peripheral side of the governor pulley 110b when the rotation speed of the governor pulley 110b is slow. Works like.

The limit switch 111 includes a switch lever (not shown) for switching power supply / cutoff to the hoisting machine 107. The switch lever is positioned at a position where power is supplied to the hoist 107 in normal times, and cuts off the power supply to the hoist 107 when urged by the rotary weight of the governor 110. Displace to position.

The rotary weight of the speed governor 110 is displaced to a position where the switch lever cuts off the power supply to the hoisting machine 107 when the ascending / descending speed of the basket 102 becomes a constant speed or higher with respect to the rated speed. As such, urge the switch lever. As a result, when the speed of the basket 102 is exceeded, the operation of the hoisting machine 107 can be stopped and the basket 102 can be stopped.

Further, the elevator 100 may be provided with an emergency stop device (not shown). The emergency stop device forces the operation of the basket 102 when the operation of the basket 102 and the operation of the governor rope 110a are different, that is, when the basket 102 is operating even though the governor rope 110a is stopped. Stop it. Since the emergency stop device can be easily realized by using various known techniques, the description thereof will be omitted.

The basket 102 is provided with an operation panel 102b. The operation panel 102b is provided with various operation buttons and a display for displaying the floor on which the basket 102 is located (see FIG. 2). Further, the basket 102 is provided with various sensors (see FIG. 3) such as a motor for opening and closing the door 102a, a door opening / closing sensor, an obstacle detection device, a load sensor, and a buzzer (not shown). ..

A basket upper box 112 is provided on the upper portion of the basket 102. The upper basket box 112 is provided, for example, on the ceiling plate of the basket 102, that is, outside the basket 102. The basket upper box 112 contains a substrate constituting an electric circuit including a power supply circuit, a control circuit, and the like.

Various loads provided on the basket 102, such as an operation panel 102b, a motor for opening and closing the door 102a, a door opening / closing sensor, an obstacle detection device, various sensors such as a load sensor, and a buzzer, are loaded on the substrate contained in the basket top box 112. It is electrically connected to the electric circuit of. A relay, a transformer, an inverter, or the like may be interposed between the various loads provided in the basket 102 and the electric circuit.

Relays, transformers or inverters may be mounted on electrical circuits. Specifically, for example, a motor for opening and closing the door 102a and an electric circuit can be connected via an inverter. Thereby, the opening / closing speed of the door 102a can be controlled.

The motor that opens and closes the door 102a can rotate in the forward and reverse directions, for example, it rotates in the forward direction when the door 102a is opened, and rotates in the reverse direction when the door 102a is closed. A motor for opening and closing the door 102a is provided, for example, on the ceiling plate of the basket 102. The door open / close sensor detects the open / closed state of the door 102a. The door open / close sensor can be realized by, for example, a micro switch or a photoelectric sensor whose output changes depending on whether the door 102a or the door 104a is in the open state or the closed state.

The obstacle detection device detects that an object such as a person is caught between the pair of doors 102a. Specifically, the obstacle detection device is provided, for example, between the pair of doors 102a and urged to project in the opening direction of the door 102a, or the safety shoe is inside the door 102a. It can be configured by a micro switch or the like that outputs a signal indicating that an object is caught between the pair of doors 102a when pushed into the door.

The load sensor detects the load on the basket 102. Specifically, the load sensor can be realized, for example, by a load cell. The load cell is provided, for example, between the bottom of the basket 102 and the basket frame. The buzzer outputs a buzzer sound according to the detection result of the load sensor. The buzzer outputs a buzzer sound when the load (mass) in the basket 102 exceeds a predetermined mass such as the rated load (mass) applied to the basket 102.

(Configuration of remote monitoring support device for elevator 100)
Next, the configuration of the remote monitoring support device for the elevator will be described. FIG. 2 is an explanatory diagram showing a configuration of a remote monitoring support device for the elevator 100 according to the embodiment of the present invention. In FIG. 2, the remote monitoring support device 200 of the elevator 100 according to the embodiment of the present invention includes a voltage conversion circuit 201, a data output circuit 202, and a wireless transmitter 203.

The voltage conversion circuit 201 includes a plurality of non-voltage contacts and a plurality of voltage contacts (all of which are not shown). Each of the non-voltage contacts is connected to one of a plurality of components that output a signal according to the state of the elevator 100, and opens and closes according to the input signal.

The non-voltage contact receives input of a signal from, for example, a signal to the control panel 101, that is, a component unit that outputs a so-called "upstream signal" among the parts included in the elevator 100, and opens and closes according to the input signal. Specifically, the non-voltage contact can be connected to, for example, a sensor that detects the open / closed state of the door 102a of the basket 102.

The sensor for detecting the open / closed state of the door 102a of the basket 102 and the non-voltage contact may be connected via a timer. Thereby, for example, the input of the signal from the sensor can be accepted only when the door 102a of the basket 102 is continuously opened for a predetermined time or longer.

Specifically, the non-voltage contact may be connected to, for example, the power supply of the elevator 100. When a plurality of voltages (eg, 100V and 200V) are used in the elevator 100, the non-voltage contacts are connected to the wiring for each voltage. As a result, when the power supply to the elevator 100 is stopped due to a power failure or the like and the signal output from the power supply is stopped, the signal input to the non-voltage contact changes. It can be opened and closed.

Specifically, the non-voltage contact may be connected to, for example, the safety circuit of the elevator 100. The safety circuit of the elevator 100 outputs a signal when the state of the elevator 100 is not safe. Specifically, the safety circuit of the elevator 100, for example, when it detects an overspeed, when it detects that the basket 102 has passed the stop position on the top floor or the bottom floor, when the emergency stop device is activated, and the like. Outputs a signal to.

Specifically, the non-voltage contact may be connected to, for example, a fire alarm installed in the elevator 100 or an inverter of the hoisting machine 107 for raising and lowering the basket 102. As a result, when the fire alarm is activated or when the inverter of the hoisting machine 107 that raises and lowers the basket 102 operates other than the specified operation, the signal input can be received at the non-voltage contact.

Among the parts of the elevator 100, the non-voltage contact may be one that receives an input of a signal output from the CPU of the control panel 101, a so-called "downstream signal", and opens and closes according to the input signal. good. Specifically, the non-voltage contact may receive, for example, an input of a signal output from the control panel 101 to the hoisting machine 107.

The non-voltage contact can be realized by a relay provided with an electromagnet and a contact mechanism. In a relay, the electromagnet includes an iron core, a coil wound around the iron core, and a movable iron core that swings in contact with and detachably from the iron core. Further, in a relay, the contact mechanism includes a fixed contact portion connected to a voltage contact, a movable contact portion having a movable contact that connects to and detaches from the fixed contact provided in the fixed contact portion according to the swing of the movable iron core, and a movable contact portion. It is equipped with.

The relay is closed by attracting a movable iron piece to an iron core magnetized by a coil energized by a signal input and bringing the movable contact into contact with a fixed contact. If no signal is input, it will be in the open state. As a result, the non-voltage contact can be opened and closed according to the input signal. The number of relays that realize the no-voltage contact can be provided based on the structure of the data output circuit 202. Specifically, for example, six relays that realize non-voltage contacts can be provided.

Each voltage contact is provided corresponding to each non-voltage contact, and outputs a voltage contact signal indicating an open / closed state of the corresponding non-voltage contact. The voltage contact can be realized by a semiconductor element such as a transistor. The voltage contacts are connected to the power supply circuit. The same number of semiconductor elements that realize voltage-bearing contacts are provided as relays that realize non-voltage-contacts.

The data output circuit 202 includes a plurality of input ports and a plurality of output ports corresponding to each input port. Specifically, the data output circuit 202 includes, for example, six input ports and six output ports. Each input port is connected to a voltage contact of the voltage conversion circuit 201, and receives an input of a voltage contact signal. Text data is assigned to each output port according to the open / closed state of the corresponding non-voltage contact, and the text data corresponding to the voltage contact signal input to the corresponding input port is output.

The data output circuit 202 identifies the text data to be output from the output port corresponding to the input port based on the signal indicating the open / closed state of the corresponding non-voltage contact that has received the input at the input port, and the specified text. Output data from the corresponding output port. As a result, the data output circuit 202 can output text data from each output port according to the open / closed state of the non-voltage contact indicated by the voltage contact signal input to the input port corresponding to the output port. Both output ports are connected to the wireless transmitter 203.

Specifically, for example, "DOOR OPEN" is used for the output port corresponding to the input port connected to the voltage contact corresponding to the non-voltage contact connected to the sensor for detecting the open / closed state of the door 102a of the basket 102. Text data such as can be assigned. As a result, the data output circuit 202 can output the text data "DOOR OPEN" from the output port corresponding to the sensor that detects the open / closed state of the door 102a of the basket 102.

A plurality of text data may be assigned to each output port according to the open / closed state of the corresponding non-voltage contact. Specifically, for example, "DOOR OPEN" is used for the output port corresponding to the input port connected to the voltage contact corresponding to the non-voltage contact connected to the sensor for detecting the open / closed state of the door 102a of the basket 102. Two types of text data, "DOOR OPEN CLEAR" and "DOOR OPEN CLEAR", can be assigned.

As a result, in the data output circuit 202, the door 102a of the cage 102 is connected to the input port connected to the voltage contact corresponding to the non-voltage contact connected to the sensor that detects the open / closed state of the door 102a of the cage 102 for a predetermined time. When a signal (voltage contact signal) indicating that the state is continuously open is input, the text data "DOOR OPEN" is output from the corresponding output port, and the signal (voltage contact) is output. When the input of the signal) is stopped, the text data "DOOR OPEN CLEAR" can be output from the corresponding output port.

Specifically, for example, "POWER IS DOWN" and "POWER IS BACK" are used for the output port corresponding to the input port connected to the voltage contact corresponding to the non-voltage contact connected to the power supply of the elevator 100. Two types of text data, "ON", can be assigned.

Further, the text data assigned to each output port may include property information. This can be realized by the location, building name, management number, etc. of the elevator 100 in which the remote monitoring support device 200 is installed. Specifically, the property information is, for example, "○○ prefecture XX city △△ building", "○○ prefecture XX city △ chome ○ address", "○○ prefecture XX city △ chome ○ address △△ building". It is indicated as "□ Unit". The property information is not limited to a specific location, and may be indicated by a management number, an abbreviation, or the like.

Specifically, the output port may have text such as "POWER IS DOWN: XX city △△ building" or "POWER IS BACK ON: XX city △△ building". You can assign a message. As a result, it is possible to easily and surely inform which property (elevator 100) the problem has occurred.

The wireless transmitter 203 transmits a text message to which a predetermined telephone number is designated as a destination based on the text data output from the data output circuit 202. The text message includes, for example, text (character) data such as "DOOR OPEN" and information that can identify a telephone number assigned to a terminal device to which the text message is sent. The terminal device to which the text message is transmitted can be realized by, for example, a portable telephone carried by a worker who performs maintenance management of the elevator 100.

(Example of wireless transmitter 203)
Next, an example of the wireless transmitter 203 will be described. FIG. 3 is an explanatory diagram showing an example of the wireless transmitter 203. In FIG. 3, the wireless transmitter 203 includes an input terminal 301, a microcomputer 302, a transmission circuit 303, and an antenna 304. The input terminal 301 is connected to the data output circuit 202, and outputs the signal output from the data output circuit 202 to the microcomputer 302.

The microcomputer 302 includes a CPU (Central Processing Unit) and a memory, and generates a text message based on the text data input via the input terminal 301. The memory stores, for example, a telephone number assigned to a terminal device as a destination. As a result, the wireless transmitter 203 can transmit the text message to the terminal device to which the telephone number is assigned.

In addition, the memory stores the telephone number assigned to the own device. The memory may be singular or plural. The memory may be realized by, for example, a SIM (Subscriber Identity Module) card. The SIM card has an IMSI (International Mobile Subscriber Identity), MSISDN (Mobile Subscriber Integrated Service Digital Network Number), ICCID (Integrated Circuit), etc., and an ICCID (Integrated Circuit).

The IMSI indicates a unique ID number (identification information) for identifying a telephone number assigned to each remote monitoring support device 200 (radio transmitter 203) of the elevator 100. The IMSI is a 15-digit identification number and is used for authentication for connecting to the network of the corresponding carrier together with the key information stored in the SIM card. MSISDN is composed of numbers within 15 digits and indicates a so-called mobile phone number. Normally, the IMSI or MSISDN is issued by the regulatory agency and granted to the carrier. The ICCID is composed of 19-digit or 20-digit characters or numbers, and indicates the serial number of the SIM card itself.

The number of telephone numbers stored in the memory as a terminal device as a destination may be singular or plural. When storing a plurality of telephone numbers in the memory, a priority may be set for each telephone number. Alternatively, each telephone number may be associated with a time zone in which communication with the terminal device to which the telephone number is assigned can be stored.

The transmission circuit 303 includes a modulation circuit, an oscillator, an amplifier circuit, a filter, and the like. The modulation circuit turns the data string into a modulated signal. The oscillator oscillates at the frequency of the RF signal at a frequency that can be used for wireless communication. The amplifier circuit amplifies the power of the RF signal. The filter outputs a signal from which unnecessary frequency components have been removed to the antenna 304. The antenna 304 radiates a radio wave based on a text message output from the transmission circuit 303 into space.

The wireless transmitter 203 uses a unique ID number assigned to each remote monitoring support device 200 (radio transmitter 203) of the elevator 100 to perform circuit-switched communication. Specifically, the wireless transmitter 203 uses a service called SMS (Short Message Service) for transmitting and receiving text-format messages to connect a voice line (traffic channel) through which designated voice is passed and the voice line. A text message is transmitted by communication by a circuit-switched method on a circuit-switched network composed of a signal line (signaling channel) to be controlled.

Since SMS is a so-called center mail type message service that sends a text message to a destination mobile phone via an SMS center server computer, the text message is temporarily stored in the SMS center server computer and then sent. It is transmitted to a terminal device such as a mobile phone. Therefore, if the mobile phone to which the text message is sent is out of the communication range or the power is not turned on and cannot be received, when the mobile phone becomes receivable. Is sent to the mobile phone again.

As a result, the text message transmitted when the destination mobile phone is in a non-receivable state can be transmitted again when the mobile phone is in a receivable state. Further, by using SMS, a text message can be transmitted regardless of the carrier that provides the communication service of the portable telephone.

In the remote monitoring support device 200 of the elevator 100, the voltage conversion circuit 201, the data output circuit 202, and the wireless transmitter 203 can be housed in, for example, a single housing. In this case, the remote monitoring support device 200 of the elevator 100 is attached to, for example, the machine room of the elevator 100. By attaching the remote monitoring support device 200 to the machine room arranged at the top of the elevator 100, the text message can be reliably transmitted by the wireless transmitter 203.
