Embodiment
The transmission method of modeling data file between the superior and the subordinate's dispatching patcher that the present invention is based on JMS agreement, utilize JMS agreement, between scheduling at different levels, build a JMS system, form the system of a fast transport model message file, be convenient to scheduling at different levels and obtain more fully electric network information.Specifically can be divided into following step:
1) build the service module of the transmission of the scheduling modeling system data file based on JMS agreement and build the module of multiple scheduling modeling system data file client.
JMS is a kind of specification of message-oriented middleware system interface, and JMS provides with the one of loosely-coupled flexi mode integration application mechanism.JMS provide based on store and forward application program between asynchronous data send, i.e. application program not direct communication each other, but with the middleware communication as intermediary.JMS provides guaranteed message and sends, and Application developer is without the need to understanding the details of remote procedure call and network/communication protocol.Based on JMS agreement, build the operation module of a service, this service module, as a middleware, provides the transmission of the data file of the client of each scheduling.All dispose a client based on JMS agreement at the regulation and control integral system of the superior and the subordinate's scheduling, client can carry out the work of the file of the transmission of model data and the reception model data of screening.
2) message format of transmitting and scheduling modeling data file is defined
Transmission of messages model adopts queue (Queue) pattern, except the message body of JMS message is in order to transmit concrete file content data, increase the contents such as message source identification attribute, message bag sequence number attribute, message body size attribute, file total subpackage number attribute, the total size attribute of file, file name attribute, transmitting terminal system end pattern.For message source identification attribute: when each scheduling side client sends JMS message to other scheduling side client, message source identification attribute need be brought, this attribute is used for distinguishing message sending end, the title of message source identification attribute is decided to be here " SrcAreaId ", this attribute type is String, the naming method of message source identification, with reference to " south electric network integration operation of power networks intelligent system technical specification ", achieves the model data file that can well identify reception in south electric network integration operation of power networks intelligent system.
3) utilize the mode of timing or manual activation outwards to send message by some clients, sent to each client by service module, judge whether the scheduling modeling system data file needed for reception by client modules.
Conventional JMS message communication network structure is that message generation person and consumer are all connected to JMS service end as information client side, the forwarding of message is carried out by JMS service end, as shown in Figure 1, higher level's dispatching client A can be given out information by JMS transmission service end, subordinate dispatching client B, if C have subscribed the theme identical with higher level's dispatching client A by JMS transmission service end, then can receive the message that higher level's dispatching client A issues out, also can be subordinate dispatching client B, C carries out message response by JMS transmission service end to higher level's dispatching client A, also point-to-point message production and supplyment can be realized by queue in addition.Transmission system based on JMS agreement mainly supports the transmission of timing and manual activation two kinds startup power scheduling model file at present, and the present invention makes power consumer can carry out easily stablizing, the transmission such as model, figure fast.
