Abstract

The invention discloses a circuit, a multi-channel device and a multi-channel short message sending method, and relates to the technical field of communication. The invention is used for solving the problems that an existing short message sending mode does not have a wireless network access function and cannot realize multi-network access and network backup functions of whole system equipment. Thecircuit comprises an MCU, a 4G unit, a network transmission unit and a power supply unit. The MCU comprises a first universal input/output port, at least two second universal input/output ports and aserial peripheral interface. A first universal input/output port is used for setting a circuit where the MUC control unit is located as a master circuit module or a slave circuit module through a dial-up circuit. A second universal input/output port is used for determining the address of a slave circuit module electrically connected with the master circuit module. A serial peripheral interface isused for carrying out information interaction among a plurality of slave circuit modules electrically connected with the main circuit module. The MCU is electrically connected with the 4G unit, the network transmission unit and the power supply unit.

Description

technical field [0001] The invention relates to the technical field of communication, and more particularly to a circuit, a multi-channel device and a method for sending multi-channel short messages. Background technique [0002] For the alarm reminder and information release function in the emergency management system or monitoring and early warning system, there are mainly three implementation methods at present, one is the SMS cat with the USB (English: Universal Serial Bus, Chinese: Universal Serial Bus) interface, The network SMS server, the third is the SMS gateway. [0003] SMS cat is a short message sending device connected by USB interface. The disadvantage is that the power supply is unstable, the signal is easily interfered, the equipment integration is low, and the multi-channel device does not have the function of short message scheduling; the network short message server is a sending method that depends on the third-party short message server operator, which i...
