Description
Technical Field
The utility model relates to the technical field of elevator equipment, in particular to a light curtain capable of calming voice after an elevator is trapped by people.
Background
The existing elevator light curtain is a safety protection device for an infrared elevator door, is suitable for various vertical elevators and protects the safety of passengers. The elevator car consists of four parts, namely an infrared transmitter and an infrared receiver which are arranged on two sides of a car door of an elevator, a power box arranged on the top of the car and a special flexible cable. Under the control of the MCU, the transmitting and receiving tubes are sequentially opened to continuously scan the car door area from top to bottom to form an intensive infrared protection area. When any beam of light is blocked, the control system immediately outputs a door opening signal, the car door stops closing and rotates reversely to open until the elevator door can be normally closed after the passenger or the blocking object leaves the warning area, so that the safety protection purpose is achieved, and the occurrence of accidents caused by people being in the elevator can be avoided.
The existing light curtain only has an anti-pinch function and does not have the function of identifying people trapped in the elevator; the proportion that the stranded accident of elevator accounted for is the biggest in the elevator trouble, and behind the stranded people of elevator, the quilt person can go to take off a door, turn over and climb the action of waiting and save oneself because worry, nervous, to the people who is not familiar with the elevator principle, this kind of improper saving oneself can cause bigger incident on the contrary.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a light curtain capable of soothing voices after people are trapped by an elevator, and providing the voices for soothing voices when people are trapped.
The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a light curtain that ability pronunciation pacified after elevator is stranded people, includes transmitter, receiver and controller, the controller respectively with transmitter and receiver link to each other, still include: the acceleration sensor is connected with the controller and is used for detecting the running state of the elevator; the distance sensor is connected with the controller and is used for detecting the opening and closing state of the elevator door; the timer is connected with the controller and is used for starting timing when the running state of the elevator is changed from motion to stop; and the loudspeaker is connected with the controller and used for voice placating when the timer reaches the set time and the elevator door is in a closed state.
The distance sensor is a photoelectric converter, and the photoelectric converter is connected with a receiving unit in the receiver and is used for converting the optical signal received by the receiving unit into a voltage signal.
The acceleration sensor is mounted on top inside the elevator car.
The loudspeaker is mounted in the elevator car.
Advantageous effects
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following advantages and positive effects: according to the elevator control system, the running condition of the elevator is judged by adding the acceleration sensor, the opening and closing state of the elevator door is judged by adding the distance sensor, and voice pacification is performed when the elevator is trapped by combining the information of the acceleration sensor and the information of the distance sensor, so that how to correctly operate trapped people is guided, and safety accidents caused by improper self-rescue are avoided.

Detailed Description
The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
The embodiment of the utility model relates to a light curtain capable of calming by voice after an elevator is trapped by people, which comprises a transmitter, a receiver and a controller, wherein the controller is respectively connected with the transmitter and the receiver, and the light curtain also comprises: the acceleration sensor is connected with the controller and is used for detecting the running state of the elevator; the distance sensor is connected with the controller and is used for detecting the opening and closing state of the elevator door; the timer is connected with the controller and is used for starting timing when the running state of the elevator is changed from motion to stop; and the loudspeaker is connected with the controller, is arranged in the elevator car and is used for voice placating when the timer reaches the set time and the elevator door is in a closed state. The controller used in this embodiment is a controller with a voice chip.
The acceleration sensor in this embodiment is installed at the top in the elevator car, so this acceleration sensor can detect the motion of elevator, and the numerical value that acceleration sensor detected all is different when the elevator is in the stall state, normal operating condition and scram state, therefore can confirm the running state of elevator according to different numerical values.
The distance sensor in this embodiment is a photoelectric converter, and the photoelectric converter is connected to a receiving unit in the receiver and is configured to convert an optical signal received by the receiving unit into a voltage signal. In the embodiment, the opening and closing state of the elevator door is detected by using the emitter and the receiver of the light curtain, the photoelectric converter connected with the receiving unit in the receiver is arranged to convert the optical signal received by the receiving unit into the voltage signal, the closer the emitter is to the receiver, the stronger the optical signal received by the receiving unit is, the stronger the voltage signal converted by the photoelectric converter is, the farther the emitter is from the receiver, the weaker the optical signal received by the receiving unit is, and the weaker the voltage signal converted by the photoelectric converter is, so that the opening degree of the elevator door can be known according to the strength of the voltage signal.
As shown in fig. 2, the workflow of the light curtain capable of soothing voice after the elevator is trapped by people is as follows: when the elevator is in normal operation, the acceleration sensor can detect the current state of the elevator, and when the elevator is in sudden stop due to a fault, the acceleration sensor detects related data and transmits the data to the controller; the controller starts the timer to time after receiving the related data, when the time reaches 5 seconds, the controller controls the transmitting unit in the transmitter to work, so that the transmitting unit sends out an optical signal, at the moment, after the receiving unit in the receiver receives the optical signal, the distance sensor can convert the optical signal into a voltage signal according to the received optical signal, the opening degree of the elevator door is determined according to the voltage signal, if the opening degree of the elevator door is 0, the elevator door is not opened, at the moment, the controller controls the loudspeaker to send out voice soothing information through a voice chip of the controller, and the trapped person is guided to operate correctly.
The elevator control system can judge the running condition of the elevator by adding the acceleration sensor, judge the opening and closing state of the elevator door by adding the distance sensor, and guide the trapped people to operate correctly by combining the information of the acceleration sensor and the distance sensor to perform voice pacification when the elevator is trapped by people, thereby avoiding safety accidents caused by improper self-rescue.
