Multi-card single-standby switching method and Internet of Things equipment

Abstract

The invention discloses a multi-card single-standby switching method and an internet of things equipment. The internet of things equipment comprises a plurality of card slots, a management module, a communication module, a multiplexer switch, a processing module and a hot plug module, the management module is arranged in the processing module, the management module generates a selection signal, and the multiplexer switch receives the selection signal, selects a target card slot from the plurality of card slots according to the selection signal, and sends the communication signal to the targetcard slot. The hot plug module is used for performing power-off or power-on operation on the target card slot under the condition of receiving a card pull-out or card plug-in signal. The multi-card single-standby switching function of the Internet of Things equipment can be realized, automatic card replacement can be realized without startup and shutdown, the maintenance efficiency is improved, the labor cost is reduced, and the method can be widely applied to the technical field of the Internet of Things equipment.

Description

technical field [0001] The present application relates to the technical field of Internet of Things devices, and in particular to a multi-card single-standby switching method and an Internet of Things device. Background technique [0002] With the rapid development of IoT technology, IoT devices are widely used. These IoT devices generally use cellular mobile networks to connect to the network, and many of them on the market use single-card, single-standby mobile communication solutions. Among them, single card single standby means that the IoT device can only carry one SIM card, and only one SIM card can be used for data transmission. [0003] However, this solution can only install one IoT card. Due to the different business coverage capabilities of different operators, there will be no network signal of the current IoT card in the installed location, or when the tariff of other operators’ IoT cards drops significantly, If you want to change the IoT card of other operator...

Problems solved by technology

[0003] However, this solution can only install one IoT card. Due to the different business coverage capabilities of different operators, there will be no network signal of the current IoT card in the installed location, or when the tariff of other operators’ IoT cards drops significantly, If you want to change the IoT card of other operators, you need to go to the outdoor site to change the card. Usually, IoT devices are scattered in remote places or distribution areas, and the cost of card replacement is high and the efficiency is low.
