Description

Locomotive passenger vehicle load-carrying tester based on the WorldFIP interface

Technical field

The utility model relates to a kind of locomotive passenger vehicle load-carrying tester.

Background technology

At present, based on the control mode of industrial control field, usually still adopt the control mode of straight-through lead formula in the majority, because number of conductors is extremely many, the probability that the contact place breaks down is very big, so the reliability of system is very low, the failure rate height, and maintenance difficulty is very big.Adopt the industrial bus control mode then more and more to come into one's own.The WorldFIP network is a kind of special network that design for industrial field bus, present become a kind of abroad with the high reliability fieldbus networks of domestic a large amount of uses, but owing to professional too strong, external interface also is not convenient especially.And locomotive field WorldFIP bus is extensively used, because it is professional too strong, the equipment of a lot of manufacturers need carry out data-switching by the relevant WorldFIP gateway of outsourcing, and expense and efficiency ratio are lower.

Locomotive passenger vehicle load-carrying tester is widely used on locomotive, the load-carrying tester of using at present a lot of rolling stocks all is the parts that are independent of outside the WorldFIP network, the staff need pass through the relevant information in each compartment of device observes of pointer gauge and so on the car on each compartment, is unfavorable for centralized control and the driver grasp to whole driving situation.

Summary of the invention

For realizing the relevant information centralized control in each compartment and being convenient to the grasp of driver, a kind of locomotive passenger vehicle load-carrying tester of delivering to the band WorldFIP interface on the locomotive network that can the locomotive weight information is very fast of the utility model design to whole driving situation.

It comprises WorldFIP network redundancy interface, WorldFIP transformer isolation network interface, the WorldFIP protocol controller, the C8051F040 processor, load-carrying analog input interface, wherein WorldFIP network redundancy interface and WorldFIP transformer isolation network interface are two groups, WorldFIP network redundancy interface and two-way the linking of WorldFIP transformer isolation network interface, WorldFIP transformer isolation network interface links with the WorldFIP protocol controller is two-way again, the WorldFIP protocol controller links with the C8051F040 processor is two-way again, the C8051F040 processor again with two-way the linking of load-carrying analog input interface.WorldFIP network redundancy interface, WorldFIP transformer isolation network interface are made up of WorldFIP bus transceiver and transformer isolation device.

The beneficial effects of the utility model are: this locomotive passenger vehicle load-carrying tester substitutes traditional apparatus measures mode, helps the data centralization control analysis of rolling stock, helps driver, the crew member assurance to the locomotive overall operation.Have high reliability, high flexibility and characteristics with low cost, have wide practical use at industrial circles such as rolling stocks.

Embodiment

A kind of locomotive passenger vehicle load-carrying tester as shown in Figure 1 based on the WorldFIP interface, it comprises WorldFIP network redundancy interface, WorldFIP transformer isolation network interface, the WorldFIP protocol controller, the C8051F040 processor, load-carrying analog input interface, wherein WorldFIP network redundancy interface and WorldFIP transformer isolation network interface are two groups, WorldFIP network redundancy interface and two-way the linking of WorldFIP transformer isolation network interface, WorldFIP transformer isolation network interface links with the WorldFIP protocol controller is two-way again, the WorldFIP protocol controller links with the C8051F040 processor is two-way again, the C8051F040 processor again with two-way the linking of load-carrying analog input interface.

WorldFIP network redundancy interface and WorldFIP transformer isolation network interface are the physical interfaces of WorldFIP network, are made up of two parts: i.e. WorldFIP bus transceiver and transformer isolation device.

The transformer isolation device is that the external circuit signal of WorldFIP network is sent into the WorldFIP bus transceiver through transformer isolation, perhaps the signal of WorldFIP bus transceiver is delivered to the WorldFIP network through the transformer isolation device.

The WorldFIP bus transceiver is the electric interfaces of WorldFIP high-frequency isolation transformer, it converts the digital signal of sending here to the manchester signal, then this signal is delivered to the transformer isolation device, perhaps the manchester signal decoding that the transformer isolation device is sent here becomes digital signal, sends into the WorldFIP protocol controller.

The WorldFIP protocol controller is a WorldFIP server device, it is responsible for the data stream that variable (MPS) that processor will be transmitted or message (MSG) is packaged into WorldFIP procotol defined and delivers to the WorldFIP bus transceiver, perhaps the signal resolution that the WorldFIP bus transceiver is sent here becomes normal data and with its buffer area that deposits self in, reads for processor.

The C8051F040 processor is the core of whole gateway, and it is made up of two parts: i.e. hardware and Control Software.

The effect of hardware mainly is a work schedule of being responsible for control WorldFIP protocol controller, and the analog to digital conversion of locomotive load-carrying analog signals generates, and will be responsible for also that simultaneously monitoring voltage, dongle, working power provide etc.

Locomotive load-carrying analog signals interface is a load-carrying analog signals external interface circuit, and it is demodulated to the digital signal that the C8051F040 processor is approved with locomotive dynamic load molality analog signal, for processor processing.
