Below in conjunction with the drawings and specific embodiments, the specific embodiment of the present invention is described further:
Specific term is introduced:
TCP/IP: TCP/IP, udp protocol: User Datagram Protoco (UDP).
As shown in Figure 1, a kind of distributed radio monitoring network, be made up of miniaturized receiver module cluster, management station, client and network interconnection apparatus, network interconnection, described monitoring network realizes communication based on TCP/IP protocol suite, described client and receiver adopt Transmission Control Protocol move instruction and data, described management station adopts udp protocol and multicast to carry out scanning receiver, and all instructions use frame format as shown in Figure 2.Wherein, starting character is the 4 byte ASCII character of " EI41 ", the beginning of representative frame; Command frame command phase is the ASCII character of 16 bytes, represents different control commands; Serial number is the signless integer of 4 bytes, represents the sequence number of present frame; Data segment is divided into three parts, 4 byte signless integer representative data length of beginning, 1 byte representative data type subsequently, and remainder is data; End mark is the 2 byte ASCII character of " 00 ".
Described miniaturized receiver module cluster is made up of some miniaturized receivers, described miniaturized receiver adopts the SOC (system on a chip) based on ARM Cortex-A8 core, the CPU frequency of this SOC (system on a chip) reaches 800MHz, there are 100,000,000 LAN network interfaces, be highly suitable for the high speed data transfer as spectrum monitoring, receiver adopts Windows Embedded Compact 7 operating system, possesses Windows Socket 2 DLL (dynamic link library) of feature richness, support multiple synchronization and asynchronous mode, and support multicast.
The network communication module of miniaturized receiver have employed the asynchronous transport method based on windows messaging, and the method, by the message notification mechanism of Windows window, is controlled by the network transmission process of message distribution to data of main thread.
The network communication module of described miniaturized receiver is divided into TCP communication unit and UDP communication unit two parts.Described TCP communication unit is made up of monitor, control channel and data channel, and monitor is monitored 8080 ports, sets up and control or data channel after having connection request to arrive; Control channel for receiving the control command of distance host, and returns response results; Data channel is always under the jurisdiction of a certain control channel, is specifically designed to and sends measurement data to distance host.Receiver is open 8080 ports only, therefore only have a monitor, but can have multiple control channel, can respond the control of multiple distance host simultaneously; A control channel also can have multiple data channel, can transmit dissimilar measurement data to same distance host simultaneously.Described UDP communication unit is made up of multicast members and UDP loopback device, multicast members makes receiver can add multicast group, the search instruction of multicast group is mail at receiving management station, and UDP loopback device to management station's back response, allows management station learn the existence of this receiver based on udp protocol.
A kind of distributed radio monitoring method, comprising:
Client operational monitoring application software.
Management station's operational network management service routine.
Client-access management station obtains monitoring network inner receiver information, and client and corresponding receiver are directly set up TCP and be connected, and send instruction by command channel, controls receiver execution and specifically measures task, and obtain measurement result by data channel.
The Main Function of management station is management monitoring network, finds the receiver in network, for client provides network management services and the service of receiver another name.The service routine of management station is the Windows service of being developed by .net, can run on Microsoft's desktop operating system of present main flow as XP or Win7.
As shown in Figure 3, management station is by finding the receiver in network based on multicast and udp protocol, management station just sent a search instruction to multicast group every 120 seconds, receiver member in multicast group, after receiving search instruction, can send to 4041 ports of this management station the UDP datagram comprising receiver information.Multicast function is more powerful than broadcast capability, can cross over the main frame outside router discovery local area network (LAN), thus make monitoring network can expand to multiple local area network (LAN), even can build monitoring network on internet by VPN.
Management station has discovery table and task list two data forms, wherein finds all receiver information found in the current network of table record, and the UDP datagram that these information are returned by receiver is resolved and obtained; Receiver another name in the current test assignment of task list record and the corresponding relation of IP, task list is in charge of by client, the receiver that client is carried out additions and deletions by sending program control command to management station and renamed in task list.For client provides the function class of another name service like name server, utilize this service, client can use a understandable name to visit receiver, and the IP of receiver and host name are transparent to client.
Receiver, when bootloader, first creates the UDP socket that is bound to 4040 ports, then allows this socket add a multicast group.When management station sends search instruction toward this multicast group, all multicast members can receive this instruction, and the IP address of management station's main frame can be obtained simultaneously, so the network information of oneself and state information are sent it back management station with the form of datagram by UDP loopback device by receiver, management station like this is just aware of all network site and the state that belong to the receiver of this multicast group.
For each receiver, it is equivalent to a server, is not distinguished, as long as any main frame sends instruction according to call format toward receiver, can meet with a response to client and these two kinds of distance hosts of management station.In practice, the service routine of management station and client monitors software operate in same PC sometimes, although now IP address only has one, port is different, and this can't have any impact to the program control of receiver and transfer of data.
The present invention is the application programming interface that described client provides dynamic link library form, and this storehouse encapsulates program control command.For developer provides the most basic management and measurement function, mainly be divided into network management, receiver management, frequency domain measurement, time domain measurement four part, what these basic functions were considered in the business scope and need not requiring efforts that developer only can be absorbed in oneself on the basis in this storehouse realizes details, thus the monitoring of software that fast Development is special.Below the key point that api function storehouse realizes is described.
Due to the running environment of client too much can not be supposed, so the built-in function of client should be efficient as much as possible.Network model based on this client has selected the asynchronous transport method based on overlay model.Under this methodology, data can directly communicate with distance host in user buffering district, no longer through system buffer, thereby reduce the expense of the data Replica that layering brings.
Client is when setting up interim monitoring sub-network, 8080 ports to management station send " discovery " instruction, management station will send to client the content of discovery table, client can therefrom select certain receiver, then with the IP of this receiver and another name for parameter, 8080 ports again to management station send " interpolation " instruction, and management station will add a line in task list, record the mapping relations of this receiver another name and IP.In like manner, client can be also that parameter sends " deletion " instruction with the another name of receiver, allows management station that receiver is deleted from task list.
Client when initiating measurement task, first with receiver another name for parameter, inquire the IP address of receiver to management station, then just attempt setting up TCP with 8080 ports of this IP and be connected.Now receiver receives connection request, for this request creates a control channel, calls Accept () function and sets up with client and be connected.Such client just can send the control command of allocating and measuring parameter to receiver.
When configuring measurement parameter, client should allow receiver start and measure, and receives measurement data.But because the data volume of Monitoring Data is comparatively large, and the duration is longer, in order to still can instruction be received during transfer of data, just need for transmission data set up an other independently data channel in logic.In order to set up data channel, client first sends " port " instruction by control channel to receiver, and a port number information is carried in this instruction, is intended to the port numbers notifying the data channel that receiver will be set up.Receiver, after receiving this instruction, just creates an accurate data channel, and arranges it and belong to control channel, and then send response to client, client, after receiving response, is just attempted setting up TCP with this port with 8080 ports of receiver and is connected.After receiver receives connection request, find with it corresponding accurate data channel by IP and port information, call Accept () the function data channel that is as the criterion and open path.Such receiver just can send data by this data channel to client.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
