Abstract
The utility model relates to a GPRS wireless and CAN field bus statute transmission device which comprises a power supply system, a minimum system, a GPRS interface and a CAN interface. The minimum system is connected with the GPRS interface and the CAN interface respectively; the power supply system is connected with the minimum system and the GPRS interface, and is connected with the CAN interface through a DC/DC isolating chip; and the minimum system is connected with a communication indication module. The device is a networking device for a large amount of CAN bus equipment, has the advantages of strong real-time performance, large data throughput, good stability, high reliability and strong anti-interference ability, and is particularly suitable for spots with harsh operation environment and high requirements for operation stability and reliability, such as power plants, transformer stations, automatic network distribution system, etc.
Description
Technical field
The utility model relates to a kind of stipulations retransmission unit, and especially a kind of GPRS is wireless and CAN fieldbus stipulations retransmission unit.
Background technology
Popularizing and promoting along with the CAN fieldbus, with at a high speed, fault-tolerant ability is strong, disposing easily the CAN fieldbus, to replace old-fashioned RS485/RS232 communication mode be trend of the times, increasing appliance arrangement or be about to adopt CAN field bus communication mode in power plant, transformer station, distribution automation system, but upgrading along with equipment, the increase of amount of communication data, the situation that network point distribution is not concentrated is serious all the more, and people tend to more and more adopt that GPRS is wireless communicates.These equipment of supporting CAN communication are access network how? have a large amount of CAN bus apparatus to need access network at these, the running environment place of very severe again needs a solution.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of GPRS is provided wireless and CAN fieldbus stipulations retransmission unit, can make multichannel support the equipment of CAN bus to link network, support the two nets of the active and standby machine of background system to connect, finish the stipulations of data between CAN and the Ethernet interface simultaneously and transmit.
According to the technical scheme that the utility model provides, GPRS is wireless and CAN fieldbus stipulations retransmission unit, comprises power-supply system, minimum system, GPRS interface and CAN interface; Described minimum system connects GPRS interface and CAN interface respectively; Described power-supply system connects minimum system, GPRS interface, and connects the CAN interface by the DC/DC isolating chip.
Described minimum system is connected with the communication indicating module.
The utility model has the advantages that:
The utility model is that a kind of real-time, data throughout is big, good stability, reliability height, a large amount of CAN bus apparatus interconnection devices that antijamming capability is strong, it is more abominable to be specially adapted to running environment such as power plant, transformer station, distribution automation system, but to the stability and the place that has high requirements of reliability of operation.
Description of drawings
Fig. 1 is the utility model circuit block diagram.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1: the utility model comprises power-supply system, minimum system, GPRS interface and CAN interface; Described power-supply system connects minimum system, GPRS interface, and connects described CAN interface by the DC/DC isolating chip.Described minimum system is connected with the communication indicating module.
Power-supply system: the utility model power module uses small-sized 20W switch power module, has good EMC ability, super wide input voltage range, and it is little to generate heat, and working stability is reliable.CAN interface power supply is isolated output by DC/DC.
Minimum system: adopt high performance 32 signal processor TMS F28335, big capacity SDRAM and program FLASH adopt RTOS, have guaranteed system's good real time performance, the big data quantity handling capacity.
GPRS interface: the utlity model has a wireless submodule of GPRS, adopt the GTM900B of Huawei module.The GPRS interface circuit mainly comprises: the GTM900B of Huawei, SIM card, antenna and sim card socket.The GPRS wave point is only supported TCP client mode of operation.
The CAN interface: the utility model has two-way CAN controller, and every road CAN controller can articulate 32 CAN bus apparatus at most.
Communication indicating module: every road CAN and GPRS all are furnished with the transmitting-receiving LED light.
During networking, separate unit or many CAN equipment become bus to hang over CAN interface of the present utility model, can be with this CAN interface conjunctionn to certain port of GPRS interface by configuration.The GPRS mouth is operated in client mode, when background system will be recruited certain CAN interface equipment of survey, just dial the phone number of the utility model device, equipment can be set up Socket with server end and is connected then, carry out the data forwarding operation at last, the data forwarding that the utility model will be received this network port is to corresponding C AN interface, after this CAN device responds, data forwarding with this CAN interface equipment response arrives the corresponding network port again, use for background system, so just finish whole communication process.According to the physical location at scene, the situation of data volume becomes multiple bus to be articulated on the CAN interface of the present utility model many CAN equipment, so just can satisfy a large amount of CAN equipment networking requirements.
