Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, this hair of Detailed description of the invention is now compareed Bright specific embodiment.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit The present invention, i.e., described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually here The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations.Therefore, with Under the range of claimed invention is not intended to limit to the detailed description of the embodiment of the present invention provided in the accompanying drawings, But it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not making wound Every other embodiment obtained under the premise of the property made is worked, shall fall within the protection scope of the present invention.
Specific embodiment 1:
The present embodiment is secondly total with Ethernet (Ethernet) and CAN mainly with RS485 bus for main wire guide network Line.The advantages of playing heterogeneous networks completes microcomputerized controller (hereinafter referred to as ACC), display screen, gateway, power supply unit and diesel oil The logic control, diesel engine of this vehicle and Ta Che are realized in communication between machine by operative position selection switch and present networks system Control and two-shipper join again and the functions such as more display interfaces are shown, specific as follows:
One, hardware forms
According to network signal demand of shunting, the other factors such as Bindery security, reliability and agility determine the network system System selects hardware to see the table below 1.
Table 1
Wherein, ACC mainly carries out logic parameter operation, including locomotive logic control, diesel oil to collected various data Machine start-up and shut-down control, fault detection, diagnosis, protection and related data record, parameter setting modification etc., and can be with frequency acquisition amount Signal (locomotive speed and diesel engine speed), digital quantity signal, analog signals.Weight gang mould block is mounted in as an expansion module In ACC, mainly Ben Che or the collected information of his vehicle are sent to other side, complete two-shipper and join again.Diesel engine communication gate master If being used to and diesel engine carrying out CAN communication, diesel oil machine information is acquired, and ACC is sent to by RS485 bus.Locomotive is shown Screen (HMI) is used to show the information sent from ACC and diesel engine, and will carry out from the collected information of power supply unit macro It handles and shows.The grid topological diagram of the present embodiment is as shown in Figure 2.
Two, network is divided the work
(1) RS485 bus: it is logical that the intelligent cell in all RS485 buses is all made of Modbus-RTU agreement progress data Letter.
ACC is the control core of entire locomotive as RS485 Modbus slave station 1, completes the function such as this vehicle traction control Reconnection communication function is realized while energy.ACC is on the one hand and HMI0 communication, acquisition are transmitted through the data come from HMI1 and HMI0, and HMI0 is transmitted through the diesel engine initial data come to calculate, then by final data transmission to HIM0 and other terminals;Together When, master/slave station signal is determined according to the host setting switch on console, when configuration switch is at this parking stall, ACC determines this Vehicle is main website locomotive, is carried out and the connection again of his vehicle ACC, completes this vehicle, the interaction of his car data, realizes that two-shipper joins again.
HMI0 carries out bidirectional data transfers as RS485 Modbus main website, with ACC, is responsible for receiving the collected number of ACC Word amount, switching value, analog quantity and failure amount information etc. show on interface and alarm and record to fault message;And And communicated by diesel engine communication gate (GW7228) with diesel engine, diesel oil machine information is shown on interface.
Slave station 2 of the HMI1 as RS485 Modbus, other than acquiring and showing that main website is transmitted through and carrys out data, with power supply machine Group is communicated, and the initial data of power supply unit is acquired, and is handled collected data with macrodoce and shown final number According to.
(2) Ethernet: using the Ethernet of quick 100Mbit/s between HMI, not to each HMI setting With IP carry out transmission data, the IP setting of 3 HMI be respectively 192.168.0.100,192.168.0.101, 192.168.0.102。
HMI0 serves as the function of sending and receiving data in Ethernet, the number of this vehicle, Ta Che and HMI1 are received from ACC According to being then transferred to each display screen by Ethernet.
HMI2 acquires the information of HMI0 in the present system, for showing all information of locomotive on net inspection vehicle, is only used as It has been shown that, is not involved in control.
(3) CAN bus:
In this system, since HMI0 can not choose gateway GW7228 and diesel engine carries out with diesel engine direct communication CAN J1939 communication, acquires diesel oil machine information, and send locomotive microcomputer to by RS485.
The above is only a preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein Form should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and can be at this In the text contemplated scope, modifications can be made through the above teachings or related fields of technology or knowledge.And those skilled in the art institute into Capable modifications and changes do not depart from the spirit and scope of the present invention, then all should be in the protection scope of appended claims of the present invention It is interior.
