Abstract
The invention discloses a firefighter priority recall method for a fire elevator, which comprises the following steps: s1: the fire sensor senses fire and transmits a signal to the elevator controller, and a fireman in the lobby turns on a fireman operation switch; s2: the firefighter operates the switch to switch on the fire service position, the elevator quickly returns to the fire service passage layer, the door is opened and kept open, and only waits for the command of a firefighter in the car without receiving other commands; s3: a fireman enters the elevator car for operation, landing positions of the elevator can be displayed in the elevator car and a fire service passage layer, and the fireman searches and rescues according to signals sent by prompts in the elevator car; s4, if no door opening instruction exists in the car, the elevator directly drives the base station; if the door opening instruction exists in the car, the fire fighter needs to continuously press the door opening instruction to open the door; s5, after the search and rescue is finished, the fire fighter turns off the fire control operation switch and takes out the key, and the elevator is in a normal running state. The invention improves the rescue efficiency of firemen and avoids time loss.
Description
Technical Field
The invention relates to the technical field of fire elevators, in particular to a firefighter priority recall method for a fire elevator.
Background
With the continuous development of modern cities, various business buildings and high-rise residences become places where people work and live in daily life, people are more and more concerned about life and property safety, when a fire disaster occurs in a high-rise building, a common passenger elevator cannot be used, people cannot escape quickly through the passenger elevator, and firemen cannot rescue quickly and effectively. The fire elevator can help passengers to escape quickly, helps firefighters to rescue, and when a fire disaster occurs, the elevator of the building is automatically powered off, and the firefighter elevator can be automatically switched on and off due to the fact that a power supply is very high, can continuously operate, and can not continuously accommodate the passengers after the passengers are conveyed to a base station layer, so that the firefighters can only rescue.
Namely, a method for preferentially recalling firefighters of the fire elevators needs to be provided, so that the operation functions of the firefighters' elevators cannot be affected by the electrical faults of elevator related control systems arranged outside a landing calling device and a hoistway machine room.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a firefighter priority recall method for a fire elevator, and solves the problems in the background art.
The technical scheme is as follows: a firefighter priority recall method for a firefighter elevator comprising the steps of:
s1: when a fire occurs, the fire sensor senses the fire and transmits a signal to the elevator controller, the alarm bell rings, and a fireman in the lobby turns on the fireman operation switch;
s2: the firefighter operates the switch to switch on the fire service position, the elevator quickly returns to the fire service passage layer, the door is opened and kept open, and only waits for the command of a firefighter in the car without receiving other commands;
s3: a fireman enters the elevator car for operation, landing positions of the elevator can be displayed in the elevator car and a fire service passage layer, and the fireman searches and rescues according to signals sent by prompts in the elevator car;
s4, if no door opening instruction exists in the car, the elevator directly drives the base station; if the door opening instruction exists in the car, the fire fighter needs to continuously press the door opening instruction to open the door;
s5, after the search and rescue is finished, the fire fighter turns off the fire control operation switch and takes out the key, and the elevator is in a normal running state.
Preferably, the firefighter operating switch is arranged within 2m of the horizontal distance from the elevator door, and the height is 1.8 m-2 m.
Preferably, the firefighter operated switch is a bi-stable switch.
Preferably, when the fire fighter operates the switch to switch on the fire service position, the opened door is only the door on the fire service passage side.
Preferably, a firefighter elevator pictogram is provided where the firefighter operating switch is installed.
Compared with the related art, the particle cutting tool for the extruder provided by the invention has the following beneficial effects:
the invention provides a firefighter priority recall method for a fire elevator, which comprises two stages of firefighter priority recall and use under the control of the firefighter, wherein when a fire disaster occurs, the firefighter opens a firefighter operating switch through a key to switch on a fire service position, so that the firefighter priority recall of the elevator is realized, the rescue work efficiency of the firefighter is improved, and the time loss which is not compared is avoided.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.
Fig. 1 is a flowchart of the operation of a firefighter priority recall method for a firefighter elevator of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, a firefighter priority recall method for a fire elevator, comprising the steps of:
s1: when fire occurs, the fire sensor senses the fire and transmits a signal to the elevator controller, the alarm bell rings, a fireman in the front hall turns on the fireman operating switch, and at the moment, the machine room and the well are both turned on, so that trapped people are pacified;
s2: the firefighter operates the switch to switch on the fire service position, the elevator quickly returns to the fire service passage layer, the door is opened and kept open, and only waits for the command of a firefighter in the car without receiving other commands;
s3: a fireman enters the elevator car for operation, landing positions of the elevator can be displayed in the elevator car and a fire service passage layer, and the fireman searches and rescues according to signals sent by prompts in the elevator car;
s4, if no door opening instruction exists in the car, the elevator directly drives the base station; if the door opening instruction exists in the car, the fire fighter needs to continuously press the door opening instruction to open the door;
s5, after the search and rescue is finished, the fire fighter turns off the fire control operation switch and takes out the key, and the elevator is in a normal running state.
The firefighter operating switch is arranged within 2m of the horizontal distance from the elevator door, the height of the firefighter operating switch is 1.8 m-2 m, and the elevator can return to a fire service channel layer only when the key rotates to the firefighter service position.
The firefighter operating switch is a bi-stable switch.
When the fireman operates the switch to switch on the fire service position, the opened door is only the door at the side of the fire service passage.
