Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a low-cost low-power consumption embeds electric power thing of lithium cell multiple serial ports allies oneself with gateway as shown in fig. 1-6, including CPU and lithium cell charging management module, wherein CPU dominant frequency is 1.2G, and ROM and RAM in the CPU are 128M, make the number of times that data vibrate in a vibration cycle obtain the guarantee, make CPU's overall processing speed obtain promoting, and can cooperate with lithium cell charging management module to be connected; meanwhile, the CPU is compatible with 3G and 4G, and the CPU adopts the LTE 3GPPRel.11 technology, so that the compatibility of the CPU is ensured, and the practical effect of the gateway of the Internet of things is ensured.

A 4G module is assembled on the CPU, the maximum downlink rate supported by the CPU is 300Mbps, and the maximum uplink rate supported by the CPU is 50 Mbps; the downlink rate of 300Mbps can ensure the rate of data acquisition from a host on the network by the Internet of things gateway, and the uplink rate of 50Mbps is used for the data transmission rate when the mobile terminal sends information to the base station, and the data transmission rate are matched with each other to form information data interaction. CPU and one of them serial ports electric connection, CPU passes through circuit cooperation and lithium battery charging management module electric connection, and CPU and lithium battery charging management module all change serial ports module electric connection with SPI.

The lithium battery charging management module comprises a standby power supply and is provided with a lithium battery management circuit. When an external power supply is available, the battery only receives charging current, and automatically stops after being fully charged, and in the process, the battery cannot discharge outwards, so that continuous charging and discharging of the lithium battery are avoided, and the service life is shortened. When the external power supply is powered off, the power supply is automatically switched to the lithium battery to supply power, so that the gateway can continue to work; and the CPU and the lithium battery charging management module are connected with four serial ports through an SPI-serial port conversion module in an expanding mode.

The five serial ports are 485 ports, a plurality of signal points can be converted from the 485 ports, the conversion of a plurality of signals is realized, the 485 ports are connected with other devices, and the bidirectional result of mutual conductance of the signals can be realized. Therefore, the 485 port can be widely used for controlling a plurality of devices, such as a power utilization system, a monitoring system, a security system and the like. And simultaneously, the 485 port is used and controlled through a connected distribution computer, so that the monitoring is convenient.

The working principle is that the 4G module is assembled on the CPU, the CPU can be compatible with 3G and 4G, and the LTE 3GPPRel.11 technology is adopted, so that the compatibility of the CPU is ensured, and the practical effect of the gateway of the Internet of things is ensured. During assembly, the CPU is electrically connected with the lithium battery charging management module, so that a basic internet of things gateway processing function is achieved. In the assembling process of the internet of things gateway, except for the serial port of the CPU, the CPU and the lithium battery charging management module are electrically connected with the SPI transfer serial port module through circuits in addition, and the SPI transfer serial port module is additionally connected with at least four serial ports, and the serial ports are 485 ports.

Because the internet of things gateway in the utility model optimizes the internal installation method, integrates the CPU, the storage and the communication part into one module, and simultaneously, the peripheral circuit is simplified, thereby greatly reducing the power consumption of the whole machine, and the lithium battery charging management module can be effectively utilized to replace the existing UPS battery, so that the device can be assembled in a narrower space, and the system performance is not obviously reduced.
