A vehicle-mounted device with a network port conversion chip

Abstract

A vehicle-mounted device with a network port conversion chip, comprising a first distribution valve body, a second distribution valve body, an inflow valve body, a valve core, a sealing seat, a first sensing module, a second sensing module, a transmission shaft, a bar board, electrical box, and control module; the control module includes a single-chip microcomputer, a network port conversion chip, and a network communication device, wherein the network port conversion chip transmits signals between the single-chip microcomputer and the network communication device, and the network port conversion chip transmits signals. The port conversion chip is connected with the single-chip microcomputer through a data interface. The data interface includes an 8-bit parallel interface, an SPI interface, and an asynchronous serial port. The network port conversion chip has a built-in protocol stack firmware, and the protocol stack firmware has a built-in PPPOE protocol. The PPPOE protocol It can be used to realize the communication between the network port conversion chip and the network communication device.

Description

technical field [0001] The invention relates to the field of military management and control vehicle-mounted equipment and electronic chips (international classification number H01), in particular to a vehicle-mounted equipment with a network port conversion chip. Background technique [0002] The main task of centralized management and control equipment is to conduct centralized management, real-time monitoring and comprehensive control of various states and information of public platform equipment. The controlled objects include automobile chassis, information calendar, electric lift rod, fuel heater, lodging mechanism, Air conditioners, generator sets, power wall boxes, integrated power supplies, etc. At present, especially in the military field, the requirements for the localization and independent control of electronic components including chips are becoming more and more stringent. The core circuit boards or their core electronic components used in centralized control ...

AI Technical Summary

Problems solved by technology

The problem is that most of the main components are foreign brands, which cannot meet the requirements of localization

[0007] 4. In the specific connection process between the chip and the sensor wire in the background technology, the wire generally extends along the wire groove provided on the valve body or the electrical box, but for For the irregular valve body and the electrical box wall in the form of a square plate, its irregular or relatively large volume is not conducive to slotting, or requires a large-scale processing platform

[0008] 5. In the specific installation process of the chip and the sensor wire in the background technology, the wire is laid to the corresponding position of the chip interface and directly bent to align with the interface, which will cause inaccurate Expected wire bend

[0009]6. The valve in the background technology will include the valve-in-valve technology, that is, other valves are set in the valve core. However, although this has many functions, it does not take into account the difficulty of installation As well as the problem of installation cost, it is very difficult to manufacture and install the valve in the valve

[0010]7. Although the spliced ​​valve core of the background technology is more flexible in manufacturing and installation, the sealing of the spliced ​​part is a big problem, and there is no solution yet
