ACE based inter-process communication system and method

InactiveCN105468465ASolve cross-platform application challengesSimple structureInterprogram communicationInter-process communicationClient-side
An embodiment of the invention discloses an ACE (Adaptive Communication Environment) based inter-process communication system. The system comprises an ACE client module and an ACE service thread module, wherein the ACE service thread module comprises a receiver unit, an event processor unit and a reactor unit; the event processor unit is created after the ACE service thread module receives a business request message sent by the ACE client; the receiver unit is used for receiving the business request message sent by the ACE client; the reactor unit is used for processing the business request message received by the receiver unit, determining events from different event sources and allocating the events to the event processor unit; and the event processor unit registered in the reactor unit is used for processing the allocated events and sending a business response message generated according to a processing result to the ACE client. An embodiment of the invention furthermore provides an ACE based inter-process communication method. According to the ACE based inter-process communication system and method, the inter-process communication can be realized, the structure is simple, the transmission is efficient, and the cross-platform application range is wide.

Node accessing method of Zigbee network

The invention discloses a node accessing method of a Zigbee network. The node accessing method comprises the steps of broadcasting node information of a to-be-accessed node through a coordinator; receiving the node information and writing the node information into an address pool by a router node, starting a networking allowing function and reporting a state parameter to the coordinator; receiving the state parameter by the coordinator, and setting priority of each router node according to the state parameter; broadcasting a beacon frame by the to-be-accessed node; performing matching between the node information in the beacon frame and the node information in the address pool by the router node which receives the beacon frame, and when matching is successful, transmitting a response allowing request to the coordinator; selecting the router node with highest corresponding priority as a target router node by the coordinator according to the received response allowing requests, and allowing transmission of a response frame from the target router node to the to-be-accessed node; and receiving the response frame by the to-be-accessed node and accessing the target router node. The node accessing method settles a problem of incapability of correctly assigning a Zigbee network address on the condition of different keys, thereby preventing data exchange of illegal equipment radically.

Railway vehicle brake fusion control system and method

The invention provides a railway vehicle brake fusion control system and method. The railway vehicle brake fusion control system comprise a bullet train control units and trailer control units. Each bullet train control unit comprises a bullet train fusion controller which receives a traction force instruction and carries out traction force calculation according to a preset first condition, or receives a brake instruction and carries out total brake force calculation according to the brake instruction, calculates electric brake force and first friction brake force according to a preset secondcondition, a traction system executing device used for executing traction operation according to traction force or executing brake operation according to the electric brake force, and a first frictionbrake driving control and executing device used for executing friction braking operation according to the first friction brake force. Each trailer control unit comprises a trailer fusion controller for receiving a brake instruction and calculating second friction brake force according to a preset third condition, and a second friction brake driving control and execution device for executing friction brake operation according to the second friction brake force. Therefore, the fusion control over traction and brake is completed.

Processing method and device for shared information and computer readable storage medium

The invention provides a processing method and device for shared information and a computer readable storage medium. According to the embodiment, on the one hand, interactive operation by a first useron shared information provided by a second user is acquired, interactive resources, capable of being obtained by the first user, of the shared information are determined according to the interactiveoperation and interactive resource transfer rules of the shared information, the interactive resources, capable of being obtained by the first user, of the shared information can be transferred to a resource account of the first user, and the second user, namely a sharing user does not need to perform repeated operation on the shared information through an application to perform interactive feedback operation on a browsing user participating in the interactive operation. In this way, the technical problem that in the prior art, the sharing user performs repeated operation on the shared information through the application to perform interactive feedback operation on the browsing user participating in the interactive operation, and consequently data interaction between the application and acorresponding processing engine is increased can be effectively avoided, and therefore the processing burden on the processing engine of the application is lowered.

Node access method and device for Zigbee network

InactiveCN106851774AAvoid data interactionSolve the problem of network confusionAssess restrictionSecurity arrangementAccess methodBeacon frame
The invention discloses a node access method and device for a Zigbee network. The method comprises the following steps: a coordinator broadcasts the node information of a node to be accessed in the Zigbee network during access; a routing node receives the node information, writes the node information to a preset address pool, and opens the function of allowing to access the network; the node to be accessed broadcasts a network access request beacon frame to the Zigbee network, wherein the network access request beacon frame includes the node information of the node to be accessed; the routing node that receives the network access request beacon frame matches the node information of the node to be accessed with the node information in the own address pool, and sends a response frame to the node to be accessed when the matching is successful; and the node to be accessed receives the response frame, selects a destination routing node from the received response frame, and accesses to the destination routing node. According to the node access method and device disclosed by the invention, the problem that the Zigbee network address can be correctly assigned even when the keys are different can be solved, and the data interaction of illegal equipment can be avoided from the source.
