An object of the utility model is to provide a take emergency rescue intercom device of wireless calling function. The novel telephone conversation system has the characteristics of convenience in installation and good conversation stability.

The technical scheme of the utility model: the utility model provides a take emergency rescue intercom device of wireless calling function, is including setting up the intercom in elevator car, and the intercom includes the intercom casing, is equipped with central processing unit in the intercom casing, and the central processing unit outside is connected with FSK wireless communication module through level conversion module, level conversion module and FSK wireless communication module all set up in the intercom casing.

In the emergency rescue intercom device with the wireless calling function, the FSK wireless communication module is an ML302 type internet of things 4G module.

In the emergency rescue intercom device with the wireless calling function, the earphone and the calling key are connected to the exterior of the intercom.

In the emergency rescue intercom device with the wireless calling function, the intercom shell is formed by mutually connecting the fixed frame, the base and the upper cover plate, the fixed frame is externally detachably connected with the control panel of the elevator car, the central processing unit, the level conversion module and the FSK wireless communication module are all installed on the base, and the base and the upper cover plate are all located on the outer side of the control panel.

In the emergency rescue intercom device with the wireless calling function, the control panel is provided with the placing opening, the fixed frame is annular, the inner side of the fixed frame is buckled into the placing opening and is connected with the installation piece in a buckling mode, and the installation piece, the control panel, the base and the upper cover plate are connected with one another through the bolts.

Compared with the prior art, the utility model has the advantages that the central processing unit of the interphone is connected with the FSK wireless communication module through the level conversion module, so that the interphone can carry out wireless calling with the outside, and compared with the existing communication structure, the arrangement and wiring of signal lines are saved, thereby facilitating the installation of the utility model and improving the conversation stability; by optimizing the FSK wireless communication module into an ML302 type Internet of things 4G module, the interphone of the utility model can be compatible with a 4G network of a mobile network, a Unicom network and an electric core at the same time, and both a GSM network and a CDMA network can be used, thereby further improving the conversation stability and the calling effect of the utility model; through the structural matching of the fixed frame and the mounting plate, the base and the upper cover plate can be arranged outside the control panel while the mounting stability of the interphone is ensured, so that the installation and wiring of the interphone are further facilitated; through the optimization to fixed frame and installation piece appearance and connection structure, can also make the intercom casing just can carry out the dismouting in elevator car, and need not to dismantle control panel, further reduced the utility model discloses an installation degree of difficulty. Therefore, the utility model has the characteristics of easy to assemble, conversation stability is good.
