PC/104-Plus multifunctional data acquisition card

Abstract

The invention relates to a PC / 104-Plus multifunctional data acquisition card belonging to the fields of data acquisition, vehicular communication and positioning technologies. The high-integrity card in the PC / 104 structure comprises a smart CAN (Controller Area Network) and RS232 (Recommended Standard232) conversion card, a GPS (Global Positioning System), a GPRS (General Packet Radio Service) radio network and an IPC (Industrial Personal Computer) capable of automatically starting and shutting down and ensures the normal operation of the system. On a basis of the smart CAN and RS232 conversion card, the / 104-Plus multifunctional data acquisition card is integrated with the GPS and the GPRS radio network module, realizes the positioning function of the GPS and the data acquisition function and the CAN and can transmit data to a control chamber through the GPRS radio network so that managers are convenient to know various kinds of data information in time. The card adopts the PC / 104 structure, and has the advantages of ultrahigh electric and mechanical characteristic reliability, low power consumption, little heat generation and ultrahigh flexibility, and the cards can be reliably connected through self stacks so as to have strong antiknock capacity.

Description

technical field [0001] The invention relates to a PC / 104-Plus multifunctional data acquisition card, belonging to the technical fields of data acquisition, vehicle communication and positioning. Background technique [0002] (1) CAN, the full name is "Controller Area Network", that is, the controller area network, which is an international standard, high-cost field bus, developed by the German BOSCH company, which is famous for the research and development and production of automotive electronic products, and eventually became It is an international standard and is one of the most widely used field buses in the world. In North America and Western Europe, the CAN bus protocol has become a standard bus for automotive computer control systems and embedded industrial control LANs. CAN is a multi-master serial communication bus with high real-time performance. In recent years, its high reliability and good error detection capabilities have been valued, and it is widely used in a...

Problems solved by technology

[0014] (1) The existing technology is mainly CAN and RS-232 intelligent data conversion card realized independently, and a wireless communication module of PC / 104 structure integrating GPRS and GPS realized independently, and the degree of integration is not high

[0015] (2) When the industrial computer is used as a vehicle-mounted product, if the industrial computer is turned on or off at any time as the car starts or stops, it will cause devastating damage to the industrial computer system for a long time, causing the industrial computer to fail to work normally.

But at present this kind of board is only used as a separate product
