Title:
NETWORK ENHANCEMENT SYSTEM AND METHOD FOR CONFINED SPACE OF ELEVATOR HOISTWAY
Document Type and Number:
WIPO Patent Application WO/2020/114314
Kind Code:
A1
Abstract:
Disclosed are a network enhancement system and method for the confined space of an elevator hoistway. The system comprises a signal receiver and a signal diverger, wherein the signal receiver comprises a network signal receiving module, a signal transformation module, a signal processing module, a signal modulation module, a signal power amplification module and a network signal diverging module. The network signal receiving module receives a network signal needing to be transformed, and transmits the signal to the signal transformation module; the signal transformation module converts the network signal into an electrical signal, and transmits same to the signal processing module; the signal processing module processes the electrical signal, and outputs an electrical signal having a waveform and frequency identical to those of the electrical signal and having a higher intensity; the signal modulation module loads the electrical signal onto an electromagnetic carrier to regenerate a network signal; and finally, the signal power amplification module amplifies the power of the network signal. The present invention can effectively improve the intensity of a network signal, and greatly improve the transmission efficiency of the network signal in the confined space of an elevator hoistway.
