Description

  The present invention relates to an elevator safety device using pair information of an IC tag and a method for repairing the elevator safety device.

  When an owner with a pet uses an elevator, only the pet jumps into or out of the car before the elevator door closes, causing the owner and the pet to separate into the car and the landing. The door may be closed in a closed state. Even in such a situation, if the pet is connected by a predetermined string, the door can be re-opened or the car that has started to move up and down can be stopped by the conventional safety shoe device. For example, as such a conventional elevator safety shoe device, a shoe body disposed at an edge of an elevator door and attached at least to the door through a pair of levers, and the shoe body, And a switch that outputs a signal to open the door and switch to the operation when it is retracted during the closing operation. A support shaft is pivotally attached to a pair of levers, and the shoe body is supported rotatably on the support shaft. In addition, the shoe body has a sectional shape that is an arc centered on the support shaft, and a safety switch that outputs at least a door opening command signal when the shoe body rotates around the support shaft. (See Patent Document 1).

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an elevator safety device according to Embodiment 1 of the present invention. In FIG. 1, 1a is an IC tag attached to a pet, 1b is an IC tag possessed by a pet owner to which the IC tag 1a is attached, and 2 is provided in a cage that moves up and down in an elevator hoistway. A detector for detecting information of an IC tag in a cage including the IC tag 1a attached and the IC tag 1b possessed by the owner of the pet; 3, a recording unit in which information of a predetermined IC tag is recorded in advance; 4 is based on the information of the IC tag detected by the detector 2 provided in the car and the information of the IC tag recorded in the recording unit 3 in advance, and the pet and the owner of this pet A determination unit 5 for determining whether or not the vehicle is divided into two, a control unit for performing elevator car up / down control and door opening / closing control based on the determination result of the determination unit 4, and 6 connected to the recording unit 3 To be done More, delete and change of registered IC tag information in the additional or recording unit 3 of the IC tag information to the recording unit 3, a data input device consisting of a PC or the like. The IC tag 1a attached to the pet and the IC tag 1b possessed by the pet owner are paired, and the recording unit 3 includes the individual information of the IC tags 1a and 1b and the pair information. Are recorded in advance. Further, when there are a plurality of pets, an IC tag having the same pair information is attached to each pet.

Next, the operation of the elevator safety apparatus having such a configuration will be described.
FIG. 2 is a flowchart showing the operation of the elevator safety device according to Embodiment 1 of the present invention, and shows the operation of the safety device when a certain pet and the owner of this pet get into the elevator car. . First, the pet owner attaches the IC tag 1a for pets to his / her pet and possesses the IC tag 1b for owners. Here, the IC tag 1a for pets may be pre-attached to a pet collar or detachable so as to be attached to a collar or the like when using an elevator. Further, the owner's IC tag 1b may be one that has a shape that is easy to carry, or one that is attached in advance to personal belongings that are always carried when going out. For example, when a pet is always connected with a string when going out with the pet, the IC tag 1b may be attached to the handle portion of the string.

  When the pet to which the IC tag 1a is attached and the owner of the pet having the IC tag 1b get on the elevator car (step S101), the information on the IC tags 1a and 1b is detected by the detector 2 attached to the car. It is detected (step S102). When the detector 2 detects the information of the IC tags 1a and 1b in the car, that is, the individual information and the pair information of the IC tags 1a and 1b (step S103), the detector 2 detects the detected IC tag 1a. And 1b are output to the determination unit 4. The determination unit 4 compares the information of the IC tags 1a and 1b input from the detector 2 with the information of a predetermined IC tag registered in advance in the recording unit 3, and the pet and the owner of the pet are in the cage. It is determined whether or not it is separated from the landing (step S104). Specifically, first, the IC tag 1b having the same pair information as the IC tag 1a detected by the detector 2 is specified from the recording unit 3, and has the same pair information as the IC tag 1a. It is determined whether or not the IC tag 1b is detected by the detector 2 in the car. Next, an IC tag 1a having the same pair information as the IC tag 1b detected by the detector 2 is identified from the recording unit 3, and the IC tag 1a having the same pair information as the IC tag 1b is identified. It is determined whether or not the car is detected by the detector 2 in the car. That is, the determination unit 4 determines whether or not there is an unpaired IC tag in the car.

  Here, when it is determined by the determination unit 4 that the pet and the owner of the pet are both in the car or not in the car, that is, an IC that is not paired in the car. When it is determined that there is no tag, based on the determination result, the control unit 5 outputs a command to continue the normal operation of the elevator (step S105). This command closes the door and starts moving to the floor where the car is registered. On the other hand, when it is determined by the determination unit 4 that the pet and the owner of the pet are separated into the car and the landing, that is, when there is an IC tag that is not paired in the car, The determination unit 4 outputs a control command to the control unit 5 (step S106), and the control unit 5 to which the control command is input performs the stop of the car movement and the door opening / closing control. Specifically, if the door is before the door starts closing, the control unit 5 controls to keep the door open (step S107). In addition, when only a pet jumps out of the car just before the door is closed, the door has already started to close when a control command is input to the control unit 5. Control is performed so as to hold the door open again after stopping the closing operation. If the door is kept open by inputting a control command to the control unit 5, the IC tag in the car is detected by the detector 2 every predetermined time, and the inside of the car is detected by the determination unit 4. The above operation is continued until it is determined that there is no IC tag that is not paired. When the pet or the owner of the pet gets into or gets out of the car and the determination unit 4 determines that there is no IC tag that is not paired in the car, the control unit 5 resumes normal operation of the elevator. Is done. That is, the door is closed and the movement is started to the floor where the car is registered.

  If the normal operation of the elevator is not resumed even after a predetermined time has elapsed after the control command is input to the control unit 5, the doors can be closed because the IC tags in the car are not paired. The reason why the door cannot be closed, the reason why the door is kept open, the content that prompts the user to close the door, etc. may be broadcast to the passengers in the car or the hall. In addition, since it is possible that the pet owner owns only his / her IC tag 1b and uses the elevator alone, a release button or the like is installed in the car, and when this release button is pressed, control is performed. The command may be canceled and the elevator may be returned to normal operation. Further, by limiting the detection of the IC tag in the car by the detecting unit 2 only when the car is stopped, a control command is output from the determining unit 4 to the control unit 5 while the car is moving. It can also be surely prevented.

  According to the first embodiment of the present invention, the pet and the owner of the pet are used as a car and a landing based on the IC tag information detected by the detector 2 and the IC tag information registered in the recording unit 3 in advance. It can be reliably determined whether or not they are separated. For this reason, it is possible to reliably prevent the door from being completely closed and the raising and lowering of the car from being started when the pet and the owner of the pet have separated from the car and the landing. . In addition, the door does not close completely when the pet and the owner of the pet are separated from the car and the landing area, preventing the car owner from rushing and pressing the emergency stop switch. Is possible.

  The elevator safety device according to the present invention can be easily applied to an existing elevator. That is, a detector 2 for detecting IC tag pair information is newly provided in the existing elevator car, and a recording function for recording the IC tag pair information and the IC tag pair information detected by the detector 2 are provided. And a determination function for determining whether or not there is an unpaired IC tag in the car based on the IC tag pair information recorded in advance by the recording function, and a door based on the determination result of the determination function. By adding a control function for performing opening / closing control to the inside of the control panel of the existing elevator, the safety device of the elevator can be easily modified. Moreover, the safety of an elevator having the same functions as the above-described functions, including a control unit that can be externally attached to an existing elevator, and a detector 2 that detects pair information of an IC tag and can be attached to an existing elevator car. The device may be retrofitted to an existing elevator.

  In the present invention, the IC tags 1a and 1b are attached to the pet and the owner of the pet, and the door opening / closing control is performed when the pet and the owner are separated from the cage and the landing. It is also possible to apply so that a child or a person with a saddle cannot use the elevator alone by changing the object to which the tag is attached or possessed.

It is a block diagram of the safety device of the elevator in Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the safety device of the elevator in Embodiment 1 of this invention.
