Technical field
The utility model relates to the distributed control governing system at the medium and small ability marshalling yard of railway hump scene, relates in particular to the distributed field controller based on the LonWorks field bus technique.
Background technology
Traditional field control technology itself exists the defective that some can't overcome.For example: a master controller can only be arranged on network structure, can't constitute how main redundant system, system reliability is poor; Data communication method is the command response formula, causes system flexibility poor; On transfer rate, also there is the bottleneck that can't overcome; Too many oversize on-the-spot line is transmitting different signals separately, and system interference is difficult to solve; Adopt that operating efficiency is low, the rim brake of poor stability and skate braking.At above deficiency, my company has developed the controllable top control system based on the LonWorks field bus technique specially, has realized the shunting service robotization under the premise that security is guaranteed.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of distributed field controller based on the LonWorks field bus technique with higher real-time to be provided.
The purpose of this utility model can be achieved through the following technical solutions: based on the distributed field controller of LonWorks field bus technique, it is characterized in that, described field controller comprises the 12V direct supply, the 24V direct supply, the 80186CPU template, input template, output template, the LonWorks network board, mainboard, described 12V direct supply, the 24V direct supply, the 80186CPU template, input template, output template, the LonWorks network board all is connected with mainboard, described input template, output template is connected by mainboard with the LonWorks network board respectively, and this LonWorks network board is connected by mainboard with the 80186CPU template.
Also comprise lightning-protection module, this lightning-protection module is located on the mainboard.
Described CPU template is the 80186CPU template.
Compared with prior art, advantage of the present utility model is:
(1) uses this product, cooperate the LonWorks field bus technique easily all devices to be connected into the interoperability net with twisted-pair feeder, saved field wiring greatly;
(2) each station track and rolling down section test the speed, survey long and the group control of controlled top is finished by field controller nearby, have higher real-time;
(3) on performance, be better than full retard top governing system, and equipment investment is lower than equipment such as employing speed reduction units, therefore is particularly suitable for Medium and Small Hump and uses.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model based on the distributed field controller of LonWorks field bus technique.
Embodiment
As shown in Figure 1, distributed field controller based on the LonWorks field bus technique, it is characterized in that, described field controller comprises the 12V direct supply, the 24V direct supply, the 80186CPU template, input template, output template, the LonWorks network board, mainboard, described 12V direct supply, the 24V direct supply, the 80186CPU template, input template, output template, the LonWorks network board all is connected with mainboard, described input template, output template is connected by mainboard with the LonWorks network board respectively, and this LonWorks network board is connected by mainboard with the 80186CPU template.Also comprise lightning-protection module, this lightning-protection module is located on the mainboard.
The field controller of controllable top control system is to be distributed in on-the-spot intelligence control system, based on the LonWorks field bus technique by twisted-pair feeder with the Central Control Room PC, be distributed in on-the-spot controller and be unified into a network.Each station track and rolling down section test the speed, survey long and the group control of controlled top is finished by field controller nearby, have higher real-time.Its feature is as follows:
(1) field controller is distributed in side, an on-the-spot railway station track and is placed in the CB2 signal transformer case, control a controlled group, and a controlled top group's controlled useful order colludes car with adjacent two and does not press same top group simultaneously, guarantees that adjusting speed accuracy is a division principle that about 20 controlled tops are 1 group of little top group;
(2) field controller can unit work, also can adopt the two-node cluster hot backup mode.When the two-node cluster hot backup mode, controlled top of master controller working control and collection measurement data; The calculation procedure that spare controller operation is identical with main frame, but do not participate in controlling, but whether constantly detect the CPU state and the input/output state of master controller correct.In a single day spare controller detects the master controller fault, and then automatically switch into master controller and substitute its work, and display alarm, prompting the maintenance personal overhaul, change;
(3) field controller has high reliability:
A. every road output circuit all adopts high power relay output, and field controller carries out back production to the output result, can detect the fault of output circuit in real time, finds to report to the police automatically after the fault;
B. output contact disposes the current limliting protective tube, can not influence other tops group when the short circuit of certain controlled top;
C. input circuit adopts current-limiting resistance to add photoelectricity coupling isolation input, can not cause the input short circuit during fault.Master controller and spare controller are gathered input state simultaneously, if the input circuit of master controller breaks down, report to the police and switch to spare controller;
(4) each field controller is made up of parts such as 12V direct supply, 24V direct supply, LONWORKS network board, 80186CPU template, input template and output templates.Be positioned at hump rolling district, collection and the processing that pedal and power frequency are surveyed the long letter breath of testing the speed of responsible switch area, and be responsible for the automatic control on controlled top, corresponding station track.Field controller lays respectively at by the station track.
