Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 1; in prior art, be configured with the Communication Gateway of 3 pairs of redundancies between main frame numerical control system (DCS) and steam turbine protection control system (TCS) altogether for realizing the exchanges data between main frame numerical control system and steam turbine protection control system.Between TCS and DCS, 3 pairs of redundancy communication gateway functions are as follows:
CM1041A with the CM 1041B of-TCS is connected with DCS 65A and 65B operating office respectively, CM1042A with the CM 1042B of TCS is connected with DCS 66A and 66B operating office respectively, this 2 pairs of gateway passes levels 1 (LEVEL1) live signal, comprise display and alarm signal that TCS send DCS HMI (man-machine interface) (LEVEL2 picture), control interlocking signal, also comprise operational order and associated lock signal that DCS send TCS.Therefore, these 2 pairs of gateways are also claimed to be LEVEL1 gateway here.
-TCS XU1 with XU2 is connected with XU (Siemens's double layered communication module) the Client A (customer end A) and Client B of DCS respectively.This pair link transmits the time tag (Time Tag Data) that TCS send DCS on-off model.Consider the time delay of gateway communication, on-off model beats markers in the source of the collection fastener of TCS side to signal, then this time tag is passed to DCS by XU.After DCS receives time tag, find Signal Matching corresponding with it by signal name, and show information in DCS daily record, alarm list.Because this 1 pair of gateway lays respectively at the LEVEL2 (level 2) of both sides' system, be therefore called LEVEL2 gateway.
In this application, 2 pairs of LEVEL1 gateways adopt Modbus over ICP/IP protocol.With reference to the 7 layer network reference models of the OSI of International Organization for standardization, this agreement can be decomposed into 5 layers, namely adopts based on the physical layer of the Ethernet protocol of IEEE802.3 and Media Access Controlled sublayer (MAC), based on the logical links sublayer (LLC) of IEEE802.2, IP-based network layer, the transport layer based on TCP and the application layer based on Modbus.Modbus communication is master slave mode, DCS gateway is main website, TCS gateway is slave station, pattern that its communication process adopts " request-response ", main website periodically asks, and slave station receives passively and asks and the content completed in request message, then performance is responded main website by response message, as shown in Figure 2.The 1 inquiry request message sent for main website in Fig. 2,2 response messages sent for slave station.Modbus, when carrying out application data and exchanging, for different transmission demands, adopts different function codes (Function Code).
The XU specialized protocol of the Siemens that what communications protocol between LEVEL2 gateway adopted is based on TCP/IP.With reference to the 7 layer network reference models of the OSI of International Organization for standardization, this agreement can be decomposed into 5 layers, namely adopts based on the physical layer of the Ethernet protocol of IEEE802.3 and Media Access Controlled sublayer (MAC), application layer based on the logical links sublayer (LLC) of IEEE802.2, IP-based network layer, the transport layer based on TCP and the PDU based on XU (process data unit).The communication of XU and the DCS gateway of TCS.XU have employed customer end/server mode, and XU is server end, and DCS gateway is client.As server end, XU initiatively can not send any request message to DCS gateway, and initiate request message by the DCS gateway as client, XU is passive receive the request message of client after, data needed for message (are generally the data stored in TCS real-time server, also may be the historical data in history server, the state information that also may produce for communication itself) from TCS internal queries out, submit to DCS gateway.Write data to the situation of XU for Third party system, principle is similar, in this application, because data are all TCS to DCS, so there is no the write data function using this XU.
According to quality control and the progress monitoring requirement of large-scale Thermal Power Station, nuclear plant's construction, all need to carry out factory testing (FT) and factory inspection and acceptance (FAT) in manufactory to power plant scene in these system shippings.And, for the device systems having complex interface and exchanges data between system, also need to carry out extra associating integration testing.By joint test, whether the correctness realized to check interface function and correlated performance meet the demands.
In existing TCS and DCS joint test process, for the test of communication, the initial method of testing used as shown in Figure 3.The test that communication signal exchanges (namely comprising analog quantity and on-off model that DCS reads from TCS, the analog quantity that DCS writes to TCS and on-off model) correctness is divided into following several situation:
(1) for the signal that DCS reads from TCS, the test of its correctness adopts, those are had in TCS operator station to the signal of operation means of intervention, then by directly making corresponding order button in the drilling of TCS operator station, send a signal to DCS, tester observation signal situation of change logging test results in the operator station of DCS side, the path involved by test is
for those signals without operation means of intervention in TCS operator station, adopt forced signal from the engineer station of TCS side to give DCS, tester observation signal situation of change logging test results in the operator station of DCS side, the path involved by test is
(2) for the signal that DCS writes to TCS, the test of its correctness adopts, those are had in DCS operator station to the signal of operation means of intervention, then by directly making corresponding order button in the drilling of DCS operator station, send a signal to TCS, tester observation signal situation of change logging test results in the operator station of TCS side, the path involved by test is
for those signals without operation means of intervention in DCS operator station, adopt forced signal from the engineer station of DCS side to give TCS, tester observation signal situation of change logging test results in the operator station of TCS side, the path involved by test is
