Embodiment
The present invention with RS-485 bus, and is described in detail the present invention using Modbus RTU and Modbus ASCII two kinds of communication protocols as specific embodiment; Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
As shown in Figure 1, the industrial safety supervisory system of the network on-line reconfiguration of the embodiment of the present invention comprises network monitoring unit and network control unit, network monitoring human-computer interaction interface three part.Network monitoring unit is made up of Modbus master station, Modbus slave station; Network control unit is made up of CAN net control.
Described Modbus master station, comprise the master station (changeable put into operation) of two different industrial control network types, by each slave station of periodicity poll, monitor whole control system operation conditions, then be presented on monitored picture with dynamic refresh data, and, dynamically change the request protocol of network primary station, whether test Modbus reconstructs successfully from node, determines supervisory layers Modbus network communication mode.
Described Modbus slave station, comprise the field apparatus of two industrial control network dynamic Partial Reconstructions, one of them slave station is as gateway, connect a net control based on CAN, i.e. Modbus/CAN gateway, Modbus/CAN gateway mainly realizes data fusion and the forwarding of bottom CAN net control and upper strata Modbus network, namely respond from Modbus master station acquires, the operation conditions of CAN net control and parameter are uploaded to main website or issue control command, and the data in CAN net control are presented on LCD; Another is Modbus gate control system control station, gate inhibition's monitoring station by the detected state of infrared sensor, access control motor.When this station has detected infrared induction, then starter motor has rotated, until this blackout.
Further, described CAN net control comprises 3 field control stations, is respectively used to monitoring field humiture, harmful vapors concentration and sends warning.
Described Modbus master station is connected with Modbus slave station and network monitoring human-computer interaction interface; CAN net control is connected with Modbus/CAN gateway.
Described network monitoring unit selection Modbus is as network communication protocol.
Described network control unit is chosen CAN and is completed real-time data communication.
As shown in Figure 2, described network monitoring human-computer interaction interface mainly comprises the total looks of network system, communication configuration, topworks's detection and parameter configuration, history alarm logging and on-site supervision.Wherein the total looks of system mainly introduce the system architecture of whole monitored picture.Communication is configured for the communication mode switching Modbus main website, can switch to Modbus ASCII or Modbus RTU.Whether topworks detects and normally works mainly for detection of warning device in CAN net control and Modbus gate inhibition's monitoring station.Parameter configuration picture is mainly used in the high alarm setting value setting humiture, smog in CAN net control.Alarm logging picture is mainly used to nearest five alarm loggings in displaying scene control station, its content comprises the beginning and ending time of warning order, type of alarm and warning, field monitor is picture stimulated Industry Control site environment, and by realtime curve on this screen, and present with corresponding animation.
As shown in Figure 3, self-defining Modbus RTU and Modbus ASCII receives and dispatches control IP kernel and is articulated in AXI bus, then controls current communication mode by Pr_ctr, thus Modbus main website determines supervisory layers Modbus network communication mode.
As shown in Figure 4, the Modbus main website cycle is to field control station sending function request message bag.When there is new task requests in this main website, then receive and dispatch IP kernel by the Modbus of LWHPS2FPGA port manipulation FPGA end.
As shown in Figure 5, when network communication protocol detection module detects present communications type and our station is inconsistent, then activate reconfigurable control module, reconfigure restructural Control on Communication district.Reconfigurable control module, first according to current detection communication protocol, selects the communication configuration file be stored in outside FLASH, rewriting portion reconstruction region.
As shown in Figure 6, in partial reconfiguration design process, except specifying fixed area for reconstruct, also devise port encapsulation layer (wrapper_region) and signal-freeze layer (freeze_region) for each reconstructed module, the reconstruction region size that communicates in native system is set to W30*H28 according to the actual requirements.Signal assemble layer is mainly the port that reconstruction region provides consistent, if when present communications uses different port numbers, this design can keep reconstruct port consistance.Signal-freeze layer is positioned at outside port encapsulation layer, all Absorbable organic halogens operations in partial reconfiguration process of this layer of primary responsibility protection reconstruction region and static region.When reconfigurable control block is activated, input signals all for reconstruction region is then set to high level by this layer; After reconstruct terminates, this layer is by releasing part freezing function and again reset reconstruction region.
In conjunction with embody rule of the present invention, the present invention is described further:
Whether unanimously with the communication protocol type in network reconfiguration region detect current network link communication type, if display communication Type-Inconsistencies both this, activate reconfigurable control block, the input signal of shielding network service reconstruction region, avoid in restructuring procedure, outer signals conversion affects network reconfiguration.Reconfigurable control block prepares reconstruct clock to the reconstruct main controlled node in FPGA, and send RECONFIGURATION REQUEST signal, this request signal shows that external request reconfigures network service reconstruction region, and this signal demand keeps high level always, occurs until reconstruct function signal.After reconstruct is ready to complete signal appearance, waits for four reconstruct clock period, and take out first 16bit data by storer baking block, and place it on the data bus of reconstruct host node.If the function signal that reconstructs of reconstruct host node is set high, illustrate that reconstruct terminates, cancel RECONFIGURATION REQUEST signal, wait for that reconstructing function signal sets to 0, cancel shielding network service reconstruction region input signal, reseting network communication reconstruction region.
Further, whole FGPA needs after configured in one piece success once, just can carry out the restructuring procedure of this embodiment, static region and network portion reconstruction region configure by this configured in one piece simultaneously simultaneously, and this process can ensure the normally work such as communication identification communication check module, application control block, memory control block.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
