A software frame of elevator signal amplifier network with self-diagnosis

The mobile signal in the elevator becomes weak because of the electromagnetic shielding effect of the elevator car, and it harmful to the user´s health and interrupt the online business, to install signal amplifier in the elevator is a useful way to strengthen the mobile phone signal, however, the failure troubled the using of signal amplifier in the distributed environment, therefore, it is necessary to design a elevator signal amplifier with self-diagnosable function. This paper is a part of the work, and proposed a software frame of elevator signal amplifier network with self-diagnosis. Analyzed the application environment and arrived an operation model of signal amplifier network with self-diagnosis firstly; put forward a four layers function frame for the management system of signal amplifier network, those are access layer, support layer, process layer and application layer, and designed the software function of signal amplifier. Based on the SPF tree, the researching algorithm, self-diagnosis process and fault diagnosis process according the function frames arrived too in the paper. The applications approved that the software frame of elevator signal amplifier network is useful, can improve the management effect and reduce the after service costs of signal amplifier using in elevator cars.
