Description

A black box device installed in an elevator, lift for people, freight, or lift for the disabled that records deceleration and impact in real time and automatically transmits them.

[0001] The present invention relates to a black box device installed in an elevator, a lift for people or freight, or a lift for the disabled, which records and automatically transmits deceleration and impact in real time, and more specifically, when an accident such as a fall, collision, or sudden stop of a passenger car occurs, or when an emergency stop device is activated and the passenger car is forcibly stopped, the black box device records the deceleration and impact of the passenger car in real time at the time of the fall, collision, or sudden stop, and automatically transmits the contents to a preset control room and related organizations immediately after the accident occurs, so that the cause of the accident and the degree of impact can be clearly and quickly identified.

[0002] Inside high-rise buildings, there are elevators installed to transport passengers to their desired floors.

[0003] The above elevator usually ascends and descends vertically by wire rope, but in some cases it is driven using hydraulics or chains.

[0004] Additionally, when constructing a high-rise building, lifts are installed to transport workers or cargo inside or outside the building.

[0005] These lifts can be classified into construction, human, freight, and cargo lifts, and are elevated by wire rope, hydraulics, or rack and pinion, and are also included in elevators in a broad sense.

[0006] And in department stores and subway stations, there are escalators that go up and down in a sloped direction, inclined elevators, and wheelchair lifts for the disabled.

[0007] Figure 1 shows an example of an elevator that ascends and descends by wire rope.

[0008] The structure of a typical elevator is composed of a car (10) for boarding passengers or loading cargo, a car door (14) provided at the front of the car (10), a counterweight (40) for maintaining weight balance with the car (10), a wire rope (W) connecting the car (10) and the counterweight (40), and a traction sheave (20) for driving the car (10).

[0009] The above traction sheave (20) is installed together with a control panel in the machine room or elevator structure on the upper part of the building, and raises and lowers the boarding car (10) while rotating in the forward and reverse directions.

[0010] In addition, a boarding car sheave (S1, S2) is provided on the upper surface of the boarding car (10), and a counterweight sheave (S3) is provided on the upper surface of the counterweight (C).

[0011] In the elevator of the above structure, one end of the wire rope (W) is fixed by the first rope fixing part (F1) provided in the machine room above the boarding car (10), and is sequentially roped to S1 → S2 → traction sheave → S3, and the other end is fixed to the second rope fixing part (F2) in the hoistway structure.

[0012] The wire rope (W) wound around each of the above sheaves is usually made up of multiple strands, and the number of strands of the wire rope increases or decreases depending on the elevator's loading.

[0013] When the traction sheave (20) in the elevator of the above structure is rotated forward and reversely, the boarding car (10) is raised and lowered along the hoistway structure, and the counterweight (40) is raised and lowered in the opposite direction to the boarding car (10).

[0014] However, these elevators can experience accidents such as falls, collisions, and sudden stops due to mechanical or electrical defects or failures in each component during operation.

[0015] Especially in the case of very tall buildings, the elevators move up and down at high speeds to facilitate passenger transportation, but if an accident such as a fall, collision, or sudden stop occurs in an elevator moving up and down at high speeds, it can lead to a serious, major accident.

[0016] To prevent this, elevators are equipped with various safety devices.

[0017] Examples include an overspeed controller (commonly called a 'governor') that detects speed exceeding the rated speed of the car, and an emergency stop device that electrically and mechanically forces the car to stop when it descends at a certain speed or more.

[0018] However, even if the above safety devices are in place, it is unavoidable that various accidents may occur due to mechanical or electrical defects in various parts, or failure or malfunction of control devices.

[0019] In other words, elevator accidents are caused by a wide variety of reasons, including wire rope slippage, breakage, derailment, guide rail derailment, electromagnetic interference, control program errors, unknown malfunctions, harmonic waves, static electricity, and lightning (in the case of outdoor elevators).

[0020] Meanwhile, the safety device operation status until the emergency stop device is activated when the boarding car exceeds the rated speed can be classified as shown in [Table 1] below.

[0021] Safety device operation situation according to boarding car speed Classification Boarding car speed ratio High Section 1 Below the rated speed Boarding car operates safely and safety device does not operate Section 2 Rated speed exceeded by 15-20% Safety circuit is blocked and brake is applied to stop boarding car Section 3 Rated speed exceeded by 20-30% Emergency stop device is activated to stop boarding car Other Rope brake When the set speed standard is exceeded or the safety circuit is blocked, the boarding car is stopped by directly braking the wire rope

[0022] First, in Section 1, where the car operates below the rated speed, the emergency stop device does not operate because the car is operating safely. In Section 2, where the car speed exceeds 15-20% of the rated speed, the safety circuit is interrupted, causing the brakes to operate and bring the car to a halt.

[0023] And in section 3 where the speed of the car exceeds 20-30% of the rated speed, the speed controller is mechanically activated to trip the wire rope connected to the emergency stop device, forcibly stopping the car.

[0024] And when a rope brake is additionally installed, the wire rope is directly braked to forcibly stop the car when the set speed limit is exceeded, the safety circuit is cut off, or the car is operated in reverse.

[0025] Meanwhile, according to the elevator safety law, in case of an emergency, if the car is forcibly stopped, the acceleration of gravity must be 1g (9.81 m / sec). 2 ) is set to stop below.

[0026] This is because if a moving car is stopped too quickly, passengers may be shocked and may suffer an accident or be injured.

[0027] Especially in high-rise buildings where elevators are moving at high speeds, if the car is stopped too quickly, it can cause a great shock to the passengers and lead to a serious accident.

[0028] However, the conventional emergency stop device has a problem in that the emergency stop device does not operate until the boarding car exceeds the rated speed and reaches a speed at which the emergency stop device operates.

[0029] In reality, when the elevator is in operation, accidents may occur due to mechanical or electrical defects, failures, damage to parts, or malfunctions of each component, not only in the second section (exceeding 15-20% of the rated speed), but also in sections that do not exceed 15% of the rated speed.

[0030] In addition, if the car is forcibly stopped in the second or third section, passengers may be subjected to 1g (9.81 m / sec) of force due to the car's left-right imbalance, collision with the buffer, etc. 2 ) There are also cases where a large impact amount is applied.

[0031] Even when the emergency stop device is activated, there are cases where the car cannot stop due to mechanical or electrical failure and continues to slide, colliding with the buffer, which is a shock absorber on the floor of the elevator shaft.

[0032] However, conventional elevators only have the function to forcibly stop the car in case of an emergency, and do not have the function to record the actual amount of shock applied to passengers in case of an accident or emergency stop.

[0033] This makes it difficult to accurately determine the cause of an accident after it occurs, and it is impossible to secure evidence that can objectively prove the cause of the accident.

[0034] In other words, after an accident occurs and the car is stopped, it is not easy to find the exact cause of the accident even if the operating status of related parts such as the speed controller or control panel is investigated.

[0035] In particular, if a large impact is applied to the passenger due to a sudden stop or collision of the car and the passenger is injured, the impact at the time of the accident must be less than 1g (9.81 m / sec) as stipulated in the safety regulations. 2 ) There is no objective way to prove whether it was less than or more than that.

[0036] Additionally, if the elevator manufacturer or maintenance company visits the accident site first and takes preemptive measures after an accident occurs, it becomes more difficult to determine the cause of the accident.

[0037] Additionally, since there is no actual data on the exact impact value at the time of the accident, it is difficult to devise measures to prevent recurrence of the accident.

[0038] Additionally, during accident investigations, it is difficult to clearly determine whether the elevator manufacturer is responsible for the accident, whether there was a problem during installation, or whether the maintenance company is responsible.

[0039] This creates a problem in that in legal disputes related to accidents, it is difficult to determine the cause of the accident and responsibility, which results in disputes not being resolved or taking a long time to be resolved.

[0040] The present invention is proposed to solve the problems of the above-mentioned prior art, and its purpose is to enable securing objective evidence data on the deceleration and impact amount of a boarding car in the event of an accident caused by a fall, collision, sudden stop, etc. of a boarding car.

[0041] In other words, in the event of an accident, the impact applied to the passengers is 1g (9.81 m / sec) as stipulated in the safety regulations. 2 ) to clearly determine whether it was less than or more than that.

[0042] Another purpose of the present invention is to prevent the elevator manufacturer or maintenance company that arrives at the scene after an accident from concealing the cause of the accident by automatically transmitting records related to the deceleration and impact of the car to the control room or related organizations immediately after the accident occurs.

[0043] Another purpose of the present invention is to enable clear identification of responsibilities among the elevator manufacturer, installer, and maintenance company when investigating the cause of an accident after the accident occurs.

[0044] Another purpose of the present invention is to secure objective data that can prove the cause of an accident, so that it can be used as evidence in legal disputes.

[0045] Another purpose of the present invention is to enable prompt compensation to accident victims.

[0046] Another object of the present invention is to prevent accidents by encouraging elevator manufacturers, installers, and maintenance companies to manufacture, install, and maintain safer products.

[0047] In order to achieve the above object, the present invention is characterized in that, in a black box device installed in an elevator, a lift for people or freight, or a lift for the disabled, the black box device monitors the operating status of a boarding car, and simultaneously records and stores the deceleration and impact amount of the boarding car in real time, and when an accident such as a fall, collision, or sudden stop occurs, the fact of the accident is automatically transmitted to a preset related agency, and the deceleration immediately before the accident and the impact amount at the time of the accident are automatically transmitted to the control room.

[0048] In addition, the black box device is characterized in that it controls the operation of the boarding car to be forcibly stopped if the deceleration or impact exceeds a set value during the speed range before the emergency stop device is activated when the boarding car exceeds the rated speed and the range after the maximum impact occurs until the boarding car stops.

[0049] In addition, the black box device is characterized by automatically transmitting the fact of the accident to a pre-set control room, emergency agencies including 119, a maintenance company, and a manager's smartphone via wired or wireless communication when an accident such as a fall, collision, or sudden stop occurs or when the emergency stop device is activated and the car stops.

[0050] In addition, the black box device is characterized by comprising a measuring unit that measures impact, inclination, deceleration, noise, and vibration, a recording unit that records and stores the measured contents, a transmitting unit that transmits the stored records and the fact of an accident, a self-rechargeable battery, and an alarm device.

[0051] In addition, the measuring unit of the black box device is characterized by including an impact amount measuring sensor, a tilting sensor, a deceleration measuring device, and a noise measuring device.

[0052] In addition, the above-mentioned impact measuring sensor is configured as a measuring device that measures gravitational acceleration, and is characterized by measuring the impact in the up-down, front-back, and left-right directions of the boarding car.

[0053] In addition, the above impact measuring sensor is 1g(9.81 m / sec 2 ) If an impact amount exceeding this amount is detected, the driving circuit of the boarding car is blocked simultaneously to immediately stop operation even if the emergency stop device has not reached the operating condition, and the contents are immediately transmitted to the designated control room and related organizations.

[0054] In addition, the tilting sensor is characterized by detecting the forward / backward and left / right tilt of the boarding car.

[0055] In addition, when the tilt detected by the tilting sensor exceeds a certain value, it is characterized by generating an alarm sound and immediately transmitting the contents to the control room, a preset maintenance company, and a manager's smartphone.

[0056] Additionally, the elevator features a CCTV camera and a voice recording device installed inside the car.

[0057] In addition, the black box device is characterized in that it is installed in any one of the control panel inside the elevator car installed inside the building, the inside of the ceiling of the elevator car, the wall inside the elevator car, and the upper surface outside the elevator car.

[0058] In addition, the black box device is characterized in that it is installed on any one of the control panel inside the passenger car of a cargo lift installed during construction work, the inside of the passenger car's ceiling, and the upper surface of the exterior of the passenger car.

[0059] In addition, the black box device is characterized by being mounted on an escalator.

[0060] According to the present invention, since the black box device records and stores in real time the deceleration and impact amount at the time of the accident in addition to the normal driving record, it has the effect of securing objective evidence regarding the cause of the accident.

[0061] In particular, in cases where passengers are subjected to a large impact due to a sudden stop or collision, it is effective in clearly determining whether the amount of impact exceeds the allowable amount specified in safety regulations.

[0062] Additionally, if the car tilts beyond a certain level due to the tilt sensor installed in the black box device, it has the effect of preventing accidents in advance by forcibly stopping the car even before the emergency stop device is activated.

[0063] Additionally, even before the emergency stop device of the car is activated, if an impact of 1g or more is applied to the passenger, the car is forcibly stopped, which has the effect of preventing an accident.

[0064] Additionally, after an accident occurs, it is effective in clearly and quickly identifying the exact cause of the accident and who is responsible.

[0065] Additionally, by transmitting the details of the accident to the relevant organizations in real time immediately after the accident occurs, it has the effect of fundamentally preventing the elevator manufacturer or maintenance company that arrives at the scene from concealing or manipulating the cause of the accident.

[0066] Additionally, by securing objective evidence regarding the cause of the accident, it has the effect of clearly identifying responsibility among the elevator manufacturer, installer, and maintenance company.

[0067] In addition, by clearly distinguishing the responsibilities of elevator manufacturers, installers, and maintenance companies, each company can be encouraged to manufacture, install, and maintain elevators with a sense of responsibility.

[0068] This has the effect of improving safety awareness in each company and reducing accidents occurring in elevators.

[0069] Additionally, it has the effect of enabling legal disputes related to accidents to be resolved quickly, as objective evidence regarding the cause of the accident can be secured.

[0070] It also has the effect of ensuring that compensation for accident victims is provided quickly by clearly identifying the cause and responsibility of the accident.

[0071] Fig. 1 is a drawing showing an example of an elevator according to conventional technology.

[0072] Figure 2 is a drawing for explaining the function of a black box device according to the present invention.

[0073] Figure 3 is a schematic diagram showing a black box device according to the present invention.

[0074] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0075] The black box device (30) according to the present invention, as shown in FIGS. 2 and 3, is a device that is installed in an elevator, a lift for people or freight, or a lift for the disabled to record and automatically transmit deceleration and impact in real time, monitor the operating status of a boarding car, and simultaneously record and store the deceleration and impact of the boarding car in real time, and automatically transmit the fact of the accident to a preset related agency when an accident such as a fall, collision, or sudden stop occurs, and automatically transmits to the control room the deceleration immediately before the accident and the recorded impact at the time of the accident.

[0076] That is, unlike conventional black boxes installed in aircraft or automobiles, the black box device (30) according to the present invention records and stores in real time not only the driving status of the vehicle, but also the deceleration and impact amount, which are key information for determining the cause of the accident, when an accident such as a fall, collision, or sudden stop of the vehicle occurs.

[0077] In addition, after an accident occurs, the details of the accident, the deceleration just before the fall or collision, and the amount of impact at the time of the accident are automatically transmitted in real time to a preset related organization, such as the control room (51).

[0078] And the details of the accident are automatically transmitted to emergency facilities including 119 (52), maintenance companies (53), and administrator smartphones (54) using wired or wireless communication.

[0079] In addition, the black box device (30) according to the present invention controls the car to be forcibly stopped by blocking the safety circuit when the deceleration or impact exceeds a set value in the speed range before the emergency stop device is activated because the car exceeds the rated speed.

[0080] That is, even before the emergency stop device is activated, if a large impact is applied to the passengers, the car is forcibly stopped to prevent an accident.

[0081] In addition, the black box device (30) according to the present invention is configured to include various sensors and measuring devices, a recording unit (35) for recording driving conditions, a transmission unit (36) for transmitting driving conditions or accident conditions to relevant organizations, a self-rechargeable battery (37), and an alarm device (38).

[0082] Here, the measuring unit of the black box device (30) is configured to include an impact amount measuring sensor (31), a tilting sensor (32), a deceleration measuring device (33), and a noise measuring device (34).

[0083] The above impact amount measuring sensor (31) is configured as a measuring device that measures gravitational acceleration and measures the impact amount in the up-down, front-back, and left-right directions of the boarding car.

[0084] In addition, the above impact measurement sensor (31) is 1g (9.81 m / sec 2 ) If an impact amount exceeding this amount is detected, the safety circuit is cut off to immediately stop the operation of the car, even if the emergency stop device has not yet reached the operating condition, and the information is immediately transmitted to the designated relevant organization.

[0085] In addition, the above tilting sensor (32) detects the forward / backward and left / right inclination of the boarding car (10).

[0086] And when the inclination detected by the tilting sensor (32) is above a certain level, an alarm sound is generated and the information is immediately transmitted to the control room (51), a preset maintenance company (53), and the manager's smartphone (54).

[0087] And the above noise meter (34) is configured to detect vibration as well as noise.

[0088] The above recorder (35) records the operating status from the moment the passenger presses the button on the control panel until the vehicle stops. In particular, the operating status is recorded in units of hours, minutes, and seconds.

[0089] In addition, the above record section (35) deletes the previous record and records it again after a certain period of time, for example, after one month or three months, to prevent excessive storage of information.

[0090] The operating conditions recorded in this way are connected to the control room computer and transmitted to the control room in real time.

[0091] The transmission of the above operation records can be done through various wireless communications, and can also be connected to the control room by wire.

[0092] Additionally, a CCTV camera and a voice recording device may be additionally installed inside the boarding car (10) if necessary.

[0093] Here, it is preferable that the voice recording device be operated from the time the emergency stop device is activated until the car stops in order to protect the privacy of the passengers.

[0094] In addition, the above black box device (30) is operated by a self-charging battery (37) so that it can operate even when the power is cut off.

[0095] In addition, the black box device (30) generates a warning sound and transmits a warning signal to the control room by means of an alarm device (38) when the power capacity of the battery falls below the normal range.

[0096] And, when the above black box device (30) is installed in an elevator provided inside a building, it can be installed in any one of the control panel inside the car, the inside of the ceiling of the car, the wall inside the car, and the upper surface outside the car.

[0097] And, when the above black box device (30) is installed in a construction lift for people and cargo installed inside or outside a building during a new construction or expansion / remodeling project, it can be installed in any one of the control panel inside the boarding car, the inside of the ceiling of the boarding car, and the outer upper surface of the boarding car.

[0098] Additionally, the above black box device (30) can also be installed in an escalator or an elevator for the disabled.

[0099] Below, the operation process of the black box device (30) according to the present invention is described.

[0100] When a passenger boards a car (10) and presses the button for the desired floor, each sensor and measuring device detects and measures the operating status of the car and records this information in the recorder (35).

[0101] That is, the recorder (35) begins to record the driving conditions, deceleration, impact, incline, noise, etc., and transmits the contents to the computer in the control room (51).

[0102] If the gravitational acceleration measured by the impact sensor is 1g (9.81m / sec) 2 ) is exceeded, the safety circuit is cut off to forcibly stop the car even before the emergency stop device is activated.

[0103] And the transmission unit (36) immediately transmits the information on the stoppage of the boarding car to the control room (51), maintenance company (53), and manager's smartphone (54).

[0104] Additionally, if the tilt value measured by the tilt sensor exceeds the set value, the car is forcibly stopped as it is judged that there is a possibility of an accident occurring in the future.

[0105] And the transmission unit (36) immediately transmits the contents to the control room (51), maintenance company (53), and manager's smartphone (54).

[0106] Additionally, if the measured value from the deceleration meter exceeds the set value, this information is transmitted to the control room (51), maintenance company (53), and management via smartphone (54).

[0107] By the above method, if an abnormality occurs during operation, necessary measures can be taken in advance even before the emergency stop device is activated.

[0108] It can also prevent accidents in which the car collides with the buffer on the elevator shaft floor due to the emergency stop device not functioning properly due to mechanical or electrical errors.

[0109] And in the event of a crash, collision, sudden stop, or when the emergency stop device is activated and the car is stopped, there is a high possibility that a fatal accident has occurred, so the information is immediately transmitted to the control room (51), maintenance company (53), and manager's smartphone (54), and, if necessary, to emergency agencies (52) including 119.

[0110] Conventional emergency stop devices installed in elevators, cargo lifts, lifts for the disabled, escalators, etc. do not operate in the speed range where the speed of the passenger car exceeds the rated speed and the overspeed controller is activated.

[0111] In other words, the conventional emergency stop device only stops the boarding car after the speed of the boarding car exceeds the rated speed and a dangerous situation arises in which the emergency stop device is electrically or mechanically activated.

[0112] In addition, in conventional elevators, when the emergency stop device is activated and the car stops, it is impossible to determine whether the actual shock applied to the passengers was less than 1g or more.

[0113] In other words, it is impossible to obtain any objective data on the deceleration and impact amount, which are key factors at the time of the accident.

[0114] In particular, if a car falls and collides with the buffer on the floor of the elevator shaft, it is impossible to know the amount of impact.

[0115] This makes it difficult to clearly determine the cause of an accident after it has occurred, and in particular, to distinguish between the responsibilities of the elevator manufacturer, installer, and maintenance company.

[0116] In order to solve these problems, the present invention seeks to apply the concept of a black box installed in an aircraft or automobile to elevators, lifts for people and cargo, lifts for the disabled, escalators, etc.

[0117] In particular, the black box device of the present invention not only stores operating conditions and sounds like a conventional black box, but also records and stores deceleration, impact, incline, noise and vibration in real time, taking into account the special characteristics of elevator accidents such as falls, collisions, and sudden stops.

[0118] And when an accident occurs, the information is automatically transmitted in real time to the preset control room and related organizations.

[0119] This allows for the acquisition of objective evidence regarding deceleration, impact amount, and incline, which are key factors in determining the cause of accidents such as falls, collisions, and sudden stops.

[0120] Additionally, the cause of the accident can be clearly and quickly identified through the evidence at the time of the accident recorded and stored in the black box device and transmitted to the control room and related organizations.

[0121] The above has been described as an example of a preferred embodiment of the present invention, and the scope of the present invention is not limited to the specific embodiments described above.

[0122] Anyone with ordinary skill in the art to which the present invention pertains will understand that various modifications and changes are possible without departing from the scope of the technical idea of ​​the present invention.
