Description

Technical Field

[0001] This utility model relates to a home elevator control system, and more particularly to a home elevator lingering reminder control system. Background Technology

[0002] With the advancement and development of elevator technology, more and more low-rise residential buildings are installing home elevators. Home elevators are elevators installed in private residences for the exclusive use of a single family member. However, when existing home elevators malfunction and stop operating, the information about trapped passengers can only be transmitted to the elevator control room by having passengers actively call the emergency call number. This lack of proactive detection of trapped passengers hinders the handling of elevator malfunctions. Therefore, there is an urgent need to develop an elevator control system with a feature to alert trapped passengers, thereby improving the safety and reliability of home elevator operation. Utility Model Content

[0003] The purpose of this invention is to provide a lingering reminder and control system for home elevators. This invention has a function to remind people who are lingering inside the elevator.

[0004] The technical solution of this utility model is as follows: a dwell reminder control system for a home elevator, including an elevator control main board, which is connected to a switching power supply and a human body detection device located in the elevator car. The human body detection device is connected in parallel with a J1 time delay relay and a J2 time delay relay. The J1 time delay relay is also connected to an alarm button on the control panel. The normally closed contact switch of the J2 time delay relay is also connected between the human body detection device and the J1 time delay relay.

[0005] In the aforementioned home elevator lingering reminder control system, the alarm button on the control panel is connected to a telephone device located on the car top.

[0006] In the aforementioned home elevator lingering reminder control system, the normally open contact of the J1 time delay relay is connected to the alarm button on the control panel.

[0007] In the aforementioned home elevator lingering reminder control system, the human body detection device is connected to the relay output point of the elevator control main board.

[0008] Compared with existing technologies, this utility model installs a human body detection device inside the elevator car. One end of the device is connected to the elevator control mainboard, and the other end is connected in parallel to J1 and J2 time-delay relays. When the elevator malfunctions, the elevator control mainboard triggers the human body detection device to detect whether anyone is trapped inside the car. The J1 time-delay relay then triggers the alarm button on the control panel, triggering an alarm. Through the coordinated operation of these structures, this utility model can proactively and effectively alert and alarm people trapped inside the elevator car when a malfunction occurs, improving safety. In summary, this utility model has an elevator occupancy alert function. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0012] Example. A home elevator's lingering reminder control system is configured as follows: Figure 1 As shown, the system includes an elevator control main board 1, which is connected to a switching power supply 7 and a human body detection device 2 located inside the elevator car. The human body detection device 2 is connected in parallel to a J1 time delay relay 3 and a J2 time delay relay 4. The J1 time delay relay 3 is also connected to an alarm button 5 on the control panel. The human body detection device 2 and the J1 time delay relay 3 are also connected to a normally closed contact switch 6 of the J2 time delay relay.

[0013] The alarm button 5 on the control panel is connected to a telephone device located on the car roof.

[0014] The normally open contact of the J1 time delay relay 3 is connected to the alarm button 5 on the control panel.

[0015] The human body detection device 2 is connected to the relay output point of the elevator control main board 1.

[0016] J1 and J2 time delay relays are energized time delay relays. J2 time delay relay 15 / 16 is a normally closed contact switch, connected in series between the human body detection device and J1 time delay relay; J1 time delay relay 15 / 18 is a set of normally open contacts.

[0017] Y7 / M7 on the elevator control main board is the relay output point of the elevator control main board, which outputs elevator fault signals.

[0018] The alarm button on the control panel is connected to the telephone device on the car roof (which dials out five pre-set telephone numbers in sequence).

[0019] The working principle of this application is as follows: When the elevator malfunctions, the elevator control main board outputs a signal, and the Y7 and M7 main board relays on the elevator control main board are turned on, which powers the human body detection device in the car. When a person is detected trapped in the car, a signal is output, the J1 time delay relay is activated, triggering the alarm button on the control panel and automatically dialing a telephone for help. The normally closed contact switch of the J2 time delay relay is opened, the J1 time delay relay is de-energized, and the alarm button on the control panel is no longer triggered.
