Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1, the real-time monitoring voice alarm system for the opening and closing of the emergency passageway safety door of the elevator waiting hall comprises a contact switch which is arranged at the position of the safety door between the waiting halls of each floor and used for detecting the opening and closing of the safety door, and a terminal which is arranged at the side of the elevator door of the first floor, wherein the terminal comprises an MCU module, a voice module and a digital display module, the contact switch which is special for the elevator and is arranged at each floor is connected with the input end of the MCU module by adopting an independent special wire harness, and the wiring mode can refer to fig. 7. Voice module and digital display module with the output of MCU module is connected, and voice module's mode of connection can refer to that figure 8 is shown, digital display module, voice module show the switching state that corresponds the floor, report corresponding floor emergency exit between stairs according to the state that detects the contact switch, and wherein MCU module, voice module and digital display module's circuit design can refer to that figure 2, figure 5, figure 4 show, and the contact switch circuit can refer to that figure 6 shows.

Optionally, an elevator is waited terraced room emergency passage emergency exit switching real-time supervision audio alert system, when the emergency exit is the trapdoor, contact switch reed end (wiring end) is located the trapdoor below, and the contact is installed on the trapdoor.

Optionally, when the emergency passage safety door is a barrier door, the contact switch reed end (wiring end) is located on one side of a door frame of the barrier door, and the contact is installed on the barrier door.

Optionally, the elevator lobby emergency passage safety door opening and closing real-time monitoring voice alarm system is characterized in that the terminal is provided with a test key of a voice module, the test key is connected with one input port of an MCU module, and a circuit of the test key is shown in fig. 3.

Optionally, the terminal is provided with a pin type programming interface connected with the MCU module.
