With the increasing number of elevators installed in tall buildings such as hotels, office buildings, apartments, etc., elevators have brought much convenience to people, and at the same time, more and more casualties and emergency losses are caused due to elevator accidents. Therefore, it has become a new topic for the elevator industry to carry out effective information collecting of elevators’ safe operation. Through the remote information collecting solution, each elevator can be real-time monitored point-to-point every day, and the operating status of each elevator can be feedback for prompt inspection and maintenance. In case of abnormality of elevators, the property management company and the duty room can be informed simultaneously, so as to carry out first aid and emergency maintenance. At the same time, those trapped in the elevator can be pacified and dredged through the voice system. 

As one of the largest elevator manufacturers and service providers in China, Hitachi Elevator has respectively established large manufacturing bases in Guangzhou, Tianjin, Shanghai, and Chengdu. The company has been dedicated to the R&D, production, marketing, installation, repairing and maintenance of all kinds of elevators, escalators, passenger conveyors, etc. With the increasing number of elevators and elevator accidents, Hitachi Elevator maintains the normal operation of the elevator system via the remote information collecting system and enhances the elevator operation safety while saving the manpower.

Due to a special elevator environment, the communication module should have low power consumption and simple configurations; it should support multiple data channel simultaneously; it can be real-time online and support APN network access, etc. It can save costs according to specific requirements while ensuring the reliability of data transmission. Moreover, since the elevator space is relatively airtight, higher requirements are imposed on the module's RF specifications, in addition to the expansion of the operator's network coverage. Through RF optimization and verification for several times, GosuncnWeLink ME3000 module has been widely used in the field of elevator information collecting, by its low drop rate, low power consumption, high signal strength, etc
