Description

Wireless intercom device for elevator

Technical Field

The utility model relates to an elevator is wireless to be talkbacked device.

Background

The existing elevator wireless intercom device needs to be provided with a corresponding wireless intercom manager in a duty room, and an elevator machine room needs to be provided with a code matching device, so that communication can be carried out only by completing code matching setting with the wireless intercom manager in the duty room when the elevator wireless intercom device is used. The duty room must have corresponding duty room personnel to guard on duty, prevent that the warning from not answering by man. The conversation is carried over with analog signals.

The traditional elevator wireless intercom device has the following defects:

1. analog signals are adopted for communication, and the capacity of resisting disturbance is poor, so that the voice is easily disturbed and distorted in the communication process, and the content of the communication is not heard;

2. the duty room must be equipped with the corresponding wireless intercom supervisor, and must be attended by someone in the duty room to pay attention to whether an alarm occurs. Therefore, manpower is wasted, and the situation that the elevator alarm information is not answered after a person in a duty room walks away is easy to occur, so that the safety guarantee of the elevator is greatly reduced;

3. if the inside of the elevator needs to realize the communication with the wireless talkback management machine, a machine room host machine for code matching needs to be placed in a machine room of the elevator for matching use. Such operations are very cumbersome, both time-consuming and not easy to manage;

4. the mobile phone or the fixed phone which can not actively call or passively call to the outside line;

5. the traditional wireless intercom is influenced by distance, the interference influence is larger when the distance is longer, the sound is worse, and the conversation cannot be carried out beyond a certain distance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a communication quality is good, the security performance is good, convenient to use and transmission distance are far away's wireless intercom device of elevator.

The utility model adopts the technical proposal that: the utility model discloses a system power supply module, communication system power module, 4G full net communication system, MCU control module and intercom module, communication system power module MCU control module reaches intercom module all with the system power module electricity is connected, communication system power module with 4G full net communication system electricity is connected, intercom module reaches 4G full net communication system all with MCU control module connects, 4G full net communication system with intercom module signal connection.

Further, the elevator wireless intercom device also comprises an intercom shell, the system power supply module, the communication system power supply module, the 4G full-network communication system, the MCU control module and the intercom module are all arranged in the intercom shell, and the intercom shell is provided with a voice call module, a key input module and a display screen in a matching manner.

The utility model has the advantages that: compared with the prior art, the elevator intercom system has poor communication quality, poor safety performance and difficult operation, in the embodiment of the utility model, a user can carry out internal conversation with the elevator intercom through the intercom module, simultaneously the intercom module can directly carry out conversation with external communication equipment through the 4G all-network communication system, the 4G all-network communication system can be matched with China Unicom, China Mobile and China telecom for use, when the user alarms through the elevator intercom, the intercom module will ring, simultaneously the elevator intercom can carry out conversation with the intercom module, if the user does not answer after 10 seconds, the MCU control module will control the 4G all-network communication system to directly communicate with the communication equipment of security personnel, thereby enabling the elevator intercom to communicate with the external security personnel, therefore, security personnel can know the danger information in time; dial as external communication equipment during the intercom module, the intercom module will carry out the jingle bell, if not listening after 10 seconds, this external communication equipment will communicate to the inside intercom of elevator with automatic switch-over to realize that external communication equipment communicates with the inside intercom of elevator, thereby convenient to use, consequently, the utility model discloses a 4G whole net communication system realizes digital signal transmission, and this kind of transmission mode is difficult to receive the interference of site factor to reduce the card pause of sound, distortion, squeal, ambient noise etc. so, the utility model has the advantages of communication quality is good, the security performance is good, convenient to use and transmission distance are far away.
