Description
Technical Field
The invention relates to the field of elevator safety, in particular to a false opening warning device of a vertical lifting type elevator hoistway door.
Background
As a means of transportation for the last 50 meters of modern human activities, elevators have become one of the important infrastructures closely related to the lives of citizens in the past decade, and particularly in recent years, the maintenance amount of elevators in China has rapidly increased, and the future will continue to rise. The elevator has more structural elements, the accidents have certain randomness and burstiness, and some certainty, and statistics show that the accident probabilities in the elevator structural elements are respectively as follows: hall door accidents account for about 80%, accidents in a hoistway account for about 15%, and other accidents account for 5%; in a hall door accident, particularly, a car stops outside a door opening area to be fatal, when passengers wait for a ladder, the car can naturally enter the elevator by being in place when seeing that the hall door is opened, and therefore the car falls into a hoistway out of control to cause casualties. At present, the safety of the elevator mainly depends on a regular maintenance or annual inspection mode, maintenance companies carry out fixed project overhaul on each component of the elevator according to regulations, and although the mode has the condition of over repair or under repair and is difficult to detect possible abnormality, the mode plays an important role in the development of the elevator industry in the past 10 years, and the hidden danger of elevator accidents is further increased along with the rapid increase of the elevator maintenance quantity.
By false hoistway door opening is meant that when the hoistway door of a floor is open, the elevator car is at another floor position or at a floor but not at a correct landing position. The elevator manufacturer has mature safety control measures such as safety contacts, mechanical door locks, automatic door closing and the like on door systems (floor hall doors, car doors) and the like, the door systems are key items for maintaining single daily work, the probability of false opening of the elevator hall doors is very low in theory, but in recent years, accidents of falling well casualties of users caused by false opening of the hall doors still exist, and the adoption of the latest scientific and technological achievements for on-line monitoring and supervision of the elevator, particularly the door systems (floor hall doors and car doors) has become an important measure for promoting the development of industry. Currently, related researches are carried out by practitioners around monitoring the door system state of an elevator, and an intelligent maintenance laboratory of the university of cincinnati in the United states monitors the running state of the door system on the basis of the traditional mechanical fault diagnosis principle on vibration signals in the process of opening and closing the door of the elevator, which are extracted through a sensor; document CN100564219C analyzes the current state of the door on line by constructing a door system dynamic model, estimating model parameters; the document CN101259930B discloses that the motor torque current is used as a main performance index to monitor and early warn the state of a door system, the digitized driving current and position signals are output through a Controller Area Network (CAN) bus, the torque current, door opening and closing position information and the combination thereof are used for comparing the threshold value of fault early warning obtained through the test of a door system test bed, and the door system fault is early warned; the document CN105398903a discloses that an alarm is started when an infrared device detects that someone falls into a vertical elevator shaft, so as to remind taking emergency measures; document CN105460725a employs monitoring of elevator landing doors; automatically judging whether the elevator is in a fault or accident state according to the logic combination of the collected different information, realizing automatic remote monitoring and alarming by the terminal of the Internet of things, and simultaneously storing the elevator information and the processing process during the whole fault or accident period; the elevator hoistway door detection alarm system provided by CN104192665B is in communication connection with an elevator black box, when the elevator black box moves in an elevator hoistway along with an elevator car, each time the elevator black box moves to one floor, the floor where the elevator car is positioned is determined according to a floor baffle in the elevator hoistway, and the elevator hoistway door detection alarm system realizes the detection alarm function of abnormal opening of an elevator hoistway door according to floor information generated by the elevator black box; document CN107037767a uses a bluetooth module to receive signals in real time, analyze and calculate the distance between the car and each layer, and then confirms the car in place through an infrared induction circuit, so as to solve the elevator shaft accident caused by the fact that the car does not reach a specified floor and the hoistway door is opened; the document CN104340796a provides an abnormal opening alarm device for an elevator hoistway door, which is provided with an interactive photoelectric emitter and a photoelectric receiver, wherein the photoelectric receiver triggers the alarm, when the elevator hoistway door is abnormally opened, the light of the photoelectric emitter is not blocked, the photoelectric emitter interacts with the photoelectric receiver, and the light reminder is triggered to emit flashing light, so that the aim of reminding people of the light when the elevator hoistway door is abnormally opened is achieved, and the falling casualties can be hopefully prevented; document CN107098239a discloses an abnormal elevator hall door alarm system formed by using the existing mature technology, which consists of N elevator hall doors, an elevator car, N in-situ detection alarm devices and a remote alarm detector, when the elevator car is parked at the accurate position of the floor and the elevator hall door is abnormally opened, as the car can not shield the plane part when the elevator hall door is closed, when a human body reaches the vicinity of the elevator hall door, the sensor detects a human body signal, the illuminance outside the hall door is greater than the illuminance increase detected by the illuminance sensor in the hall door, and the in-situ detection alarm device gives an alarm; document CN106629297a provides a device consisting of three forms, LED light, reflective sticker and phosphor, which is fixed to the wall of the elevator shaft directly opposite the door of the elevator floor, and which is able to reflect the incident light outside the elevator back along the way to alert the user when the door of the floor is open and the elevator car is not on that floor.
If a set of hoistway door false opening monitoring devices independent of an elevator control system can be arranged, the false opening of the elevator hoistway door can be effectively monitored, and the false opening of the hoistway door can be represented in a hoistway waiting area through sound and light at the first time, so that people waiting for the elevator can pay attention, the false opening of the hoistway door can be avoided, and the elevator accident caused by the false opening of the hoistway door can be obviously reduced greatly.
