具体实施方式detailed description

在本发明的各实施例中，通过在现有的通信协议中增加一组管理报文：探测请求消息(CC_DETECT_REQ)和探测响应消息(CC_DETECT_RSP)，来判断探测站点和被探测站点之间是否通信异常，从而使探测站点在获知通信异常的情况下，暂时不向被探测站点发送数据，减轻信道负担，避免了数据的丢失。In various embodiments of the present invention, by adding a set of management messages: a probe request message (CC_DETECT_REQ) and a probe response message (CC_DETECT_RSP) to an existing communication protocol, it is determined whether communication between the probe site and the detected site is performed. The abnormality causes the detecting station to temporarily send data to the detected station without knowing the communication abnormality, thereby reducing the channel burden and avoiding data loss.

下面结合具体的实施例对本发明提供的电力线通信网络的站点间通信状态检测方法进行详细描述。The method for detecting the inter-site communication state of the power line communication network provided by the present invention will be described in detail below with reference to specific embodiments.

图1为本发明实施例一提供的电力线通信网络的站点间通信状态检测方法的流程图。本实施例提供的方法可以由中央协调(Central Coordinator，CCO)站点执行，具体地，如图1所示，本实施例提供的方法可以包括：FIG. 1 is a flowchart of a method for detecting an inter-site communication state of a power line communication network according to Embodiment 1 of the present invention. The method provided in this embodiment may be performed by a Central Coordinator (CCO) site. Specifically, as shown in FIG. 1 , the method provided in this embodiment may include:

步骤101、CCO站点经预设时间间隔向基站(Station，STA)站点发送探测请求消息。 Step 101: The CCO station sends a probe request message to a station (STA, STA) station at a preset time interval.

步骤102、该CCO站点在预设时间内未接收到该STA站点发送的探测响应消息时，判定该CCO站点与该STA站点之间通信异常。Step 102: When the CCO station does not receive the probe response message sent by the STA station within a preset time, it is determined that the communication between the CCO site and the STA site is abnormal.

步骤103、该CCO站点向该电力线通信网络中的所有STA站点发送全网广播下线消息，并回收与通信异常的STA站点对应的终端设备标识(Terminal Equipment Identifier，TEI)资源；其中，该全网广播下线消息中包含该通信异常的STA站点的TEI信息，该全网广播下线消息用于指示该电力线通信网络中的所有STA站点删除与该TEI信息对应的路由信息。Step 103: The CCO station sends a network-wide broadcast offline message to all STA stations in the power line communication network, and recovers a Terminal Equipment Identifier (TEI) resource corresponding to the STA site with abnormal communication; The network broadcast offline message includes the TEI information of the STA station with the communication abnormality, and the network-wide broadcast offline message is used to indicate that all STA stations in the power line communication network delete the routing information corresponding to the TEI information.

需要说明的是，该探测请求消息中可以包括源站点字段信息和目的站点字段信息，具体地，该探测请求消息的消息格式可以如表一所示：It should be noted that the probe request message may include source site field information and destination site field information. Specifically, the message format of the probe request message may be as shown in Table 1:

表一Table I

字段Field	起始字节Start byte	大小(字节)Size (bytes)	说明Description
DTEIDTEI	00	22	目的站点字段信息Destination site information
STEISTEI	22	22	源站点字段信息Source site field information

或者，该探测请求消息中可以包括源站点字段信息、目的站点字段信息以及目的站点层级字段信息，接收到该探测请求消息的站点可以根据目的站点层级字段信息更新自身的层级信息。具体地，该探测请求消息的消息格式可以如表二所示：Alternatively, the probe request message may include source site field information, destination site field information, and destination site level field information, and the site that receives the probe request message may update its own hierarchical information according to the destination site level field information. Specifically, the message format of the probe request message may be as shown in Table 2:

表二Table II

字段Field	起始字节Start byte	大小(字节)Size (bytes)	说明Description
DTEIDTEI	00	22	目的站点字段信息Destination site information
STEISTEI	22	22	源站点字段信息Source site field information
LayerLayer	44	11	目的站点层级字段信息Destination site level field information

具体地，该探测响应消息中包括源站点字段信息和目的站点字段信息，该探测响应消息的消息格式可以如表三所示： Specifically, the probe response message includes source site field information and destination site field information, and the message format of the probe response message may be as shown in Table 3:

表三Table 3

实际应用中，字段的字节大小可以根据电力线通信网络具体支持的节点数目的多少而定，例如，若电力线通信网络支持255个节点，则DTEI和STEI字段只需要占用1个字节。本实施例对此不做具体限定。In practical applications, the byte size of the field may be determined according to the number of nodes specifically supported by the power line communication network. For example, if the power line communication network supports 255 nodes, the DTEI and STEI fields only need to occupy 1 byte. This embodiment does not specifically limit this.

本实施例中，CCO站点在管理电力线通信网络中的站点时，会维护一张站点状态表，在站点状态表中，包含了电力线通信网络中各个站点的状态信息，CCO站点将每个站点刚入网时对应的站点状态设置为初始值，其中，初始值是根据实际应用场景中的信道质量、数据的延时重发情况以及代理协调(Proxy Coordinator，PCO)站点变更时间进行设定的，例如，当站点状态值为1时表示站点活跃，当站点状态值为0时表示站点不活跃。In this embodiment, when managing a site in a power line communication network, the CCO site maintains a site state table, where the site state table contains state information of each site in the power line communication network, and the CCO site will each site just The corresponding site status is set to the initial value when the network is connected, and the initial value is set according to the channel quality in the actual application scenario, the delayed retransmission of the data, and the Proxy Coordinator (PCO) site change time, for example, When the site status value is 1, the site is active. When the site state value is 0, the site is not active.

CCO站点经预设时间间隔向STA站点发送探测请求消息，本实施例中，该预设时间间隔具体为一个信标周期T_BC，CCO站点在每个T_BC向一个STA站点发送一个探测请求消息，可以理解，在每个路由周期T_D内，CCO站点即可对电力线通信网络内的每个站点遍历一次，其中，T_D＝T_BC*站点数目。The CCO station sends a probe request message to the STA site at a preset time interval. In this embodiment, the preset time interval is specifically a beacon period T _BC , and the CCO station sends a probe request message to one STA station in each T _BC. It can be understood that within each routing period T _D , the CCO site can traverse once for each station within the power line communication network, where T _D = T _BC * number of stations.

该CCO站点在预设时间内未接收到该STA站点发送的探测响应消息时，判定该CCO站点与该STA站点之间通信异常；其中，预设时间具体可以为一个路由周期，本实施例中，若在一个路由周期内，CCO站点未接收到探测响应消息，则将站点状态表中对应站点的站点状态值减1，在站点状态值减为0之前，只要接收到探测响应消息，就将该站点的站点状态值置为初始值；当站点状态值减为0时，CCO站点即可判定与该站点之间通信异常。When the CCO site does not receive the probe response message sent by the STA station within a preset time, it is determined that the communication between the CCO site and the STA site is abnormal. The preset time may be a routing period. In this embodiment, If the CCO site does not receive the probe response message within a routing period, the site status value of the corresponding site in the site status table is decremented by 1. Before the site status value is reduced to 0, as long as the probe response message is received, The site status value of the site is set to the initial value; when the site status value is reduced to 0, the CCO site can determine the communication anomaly with the site.

在判定CCO站点与该STA站点之间通信异常后，CCO站点向电力线网络中的所有STA站点发送全网广播下线消息，强制该通信异常的STA站点下线，并回收该通信异常的STA站点对应的TEI资源。After determining that the communication between the CCO site and the STA site is abnormal, the CCO site is directed to the power line. All the STAs in the network send a broadcast message of the entire network to the offline, and the STA site that is abnormal in the communication is forced to go offline, and the TEI resource corresponding to the abnormal STA site is recovered.

在保障应用层中数据发送的应用场景中，应用层在发送数据前，先向目标站点发送探测请求消息，若收到目标站点的探测响应消息，再进行数据发送，若未收到目标站点的探测响应消息，则暂不进行数据发送；例如图2所示的网络拓扑中，某时刻D站点的应用层需要发送大批量数据给H站点，数据发送之前，应用层先进行通信状态的探测，D站点先发探测请求消息给H站点，如果在设定时间内没有收到H站点的探测响应消息，则D站点应用层暂不发送数据给H站点，隔特定时间再探测，多次探测都没收到探测响应消息的情况下，放弃与H站点的数据通信，如果在设定时间内收到H站点的探测响应消息，说明D站点和H站点通信正常，发送数据给H站点。In the application scenario of ensuring data transmission in the application layer, the application layer sends a probe request message to the target site before sending the data, and if the probe response message of the target site is received, the data is sent, if the target site is not received. If the probe response message is sent, the data transmission is not performed temporarily; for example, in the network topology shown in FIG. 2, the application layer of the D station needs to send large amounts of data to the H site at a certain time, and before the data is sent, the application layer first detects the communication state. The D site first sends a probe request message to the H site. If the probe response message of the H site is not received within the set time, the D site application layer temporarily does not send data to the H site, and then detects the probe at a specific time. If the probe response message is not received, the data communication with the H site is abandoned. If the probe response message of the H site is received within the set time, the communication between the D site and the H site is normal, and the data is sent to the H site.

本实施例的技术方案，CCO站点在获知与STA站点之间通信异常后，强制该通信异常的STA站点下线，并通知电力线通信网络中的所有STA站点该通信异常的STA站点下线，使其他STA站点删除与该通信异常的STA站点的路由信息，切断了该通信异常的STA站点与电力线通信网络中其他站点的通信；在应用层数据发送的过程中，在探测出站点间不存在通信异常时才进行数据发送，从而保障了数据通信过程，保证服务质量，且减轻了信道负担。In the technical solution of the embodiment, after the CCO station learns that the communication with the STA site is abnormal, the STA station that is abnormal in the communication is forced to go offline, and the STA site in the power line communication network is notified that the abnormal STA site is offline. The other STA stations delete the routing information of the STA station with the abnormal communication, and cut off the communication between the STA station with the abnormal communication and other stations in the power line communication network; during the application layer data transmission, there is no communication between the detected sites. Data transmission is performed only when an abnormality is performed, thereby ensuring the data communication process, ensuring the quality of service, and reducing the channel burden.

步骤302、若在该定时器时间内，该STA站点未接收到该PCO站点发送的探测响应消息，则该STA站点向CCO站点发送代理变更请求；该代理变更请求中包含目标PCO站点的TEI信息；Step 302: If the STA site does not receive the probe response message sent by the PCO station within the timer time, the STA site sends a proxy change request to the CCO site; the proxy change request includes the TEI information of the target PCO site. ;

需要说明的是，CCO站点用于管理PCO站点和STA站点，PCO站点是STA站点的父站点，CCO站点通过PCO站点与STA站点进行通信。It should be noted that the CCO site is used to manage the PCO site and the STA site, and the PCO site is the parent site of the STA site, and the CCO site communicates with the STA site through the PCO site.

该探测请求消息中可以包括源站点字段信息和目的站点字段信息，具体地，该探测请求消息的消息格式可以如上述实施例中的表一所示；该探测响应消息中可以包括源站点字段信息和目的站点字段信息，其消息格式可以如上述实施例中的表三所示；此处不再赘述。The probe request message may include source site field information and destination site field information. Specifically, the message format of the probe request message may be as shown in Table 1 in the foregoing embodiment; the probe response message may include source site field information. And the destination site field information, and the message format thereof may be as shown in Table 3 in the foregoing embodiment; details are not described herein again.

在实际应用中，本实施例可以用于站点的代理变更过程。具体地，STA站点会维护本站点的状态信息，在该STA站点刚入网时，将该STA站点的状态值置为初始值，在通信正常的情况下，该STA站点经预设时间间隔，即每个T_D周期应该接收到一次CCO站点的探测请求消息，并回复探测响应消息给CCO站点；若该STA站点在T_D周期内未接收到CCO站点的探测请求消息，则将该STA站点的状态值减1，并在每个T_BC周期检测本站点的状态值，若状态值小于初始值，则主动向PCO站点发送探测请求消息，并启动定时器，本实施例中定义该定时器为N*T_BC定时器，其中，N表示变量，该N*T_BC定时器时间会随着不同的实际应用场景以及实时的网络状态而发生变化，若在该N*T_BC定时器时间内，该STA站点未接收到PCO站点发送的探测响应消息，则会向CCO站点发送代理变更请求，进行代理变更；若在该N*T_BC定时器时间内，该STA站点接收到了PCO站点发送的探测响应消息，则说明STA站点与PCO站点之间不存在通信异常，该STA站点不需要进行代理变更。 In practical applications, this embodiment can be used for the agent change process of the site. Specifically, the STA site maintains the state information of the site. When the STA site just enters the network, the state value of the STA site is set to an initial value. When the communication is normal, the STA site passes the preset time interval. That is, each T _D period should receive a probe request message of the CCO station and reply the probe response message to the CCO station; if the STA station does not receive the probe request message of the CCO station in the T _D period, the STA site is The status value is decremented by 1, and the status value of the local station is detected in each T _BC period. If the status value is less than the initial value, the probe request message is actively sent to the PCO station, and a timer is started, which is defined in this embodiment. The device is an N*T _BC timer, where N represents a variable, and the N*T _BC timer time changes according to different actual application scenarios and real-time network status, if the N*T _BC timer time within, the STA receives the probe station does not send a response message PCO station, a change request is sent to the agent station CCO, proxy change; if in the N * T _BC timer, the STA receives the PCO site station transmits Probe response message, then the communication abnormality does not exist, the proxy does not need to change the station STA STA site between the site and the PCO.

例如，如图2中所示，假设H站点为一个STA站点，F站点为一个PCO站点，D站点为一个CCO站点；若H站点在T_D周期内未接收到D站点发送的探测请求消息，则将状态值减1，并在检测到本站点的状态值小于初始值时，向F站点发送探测请求消息，启动N*T_BC定时器；若在N*T_BC定时器时间内接收到F站点发送的探测响应消息，则表明H站点和F站点之间不存在通信异常，该H站点未接收到D站点的探测请求消息是由于F站点与D站点之间存在通信异常导致的，因此H站点不需要进行代理变更，等待F站点进行代理变更完成即可；若在N*T_BC定时器时间内未接收到F站点发送的探测响应消息，则说明H站点和F站点之间存在通信异常，需要进行代理变更。For example, as shown in FIG. 2, it is assumed that the H site is a STA site, the F site is a PCO site, and the D site is a CCO site; if the H site does not receive the probe request message sent by the D site in the T _D cycle, Then, the state value is decremented by 1, and when it is detected that the state value of the site is less than the initial value, a probe request message is sent to the F station to start the N*T _BC timer; if it is received within the N*T _BC timer time The probe response message sent by the F station indicates that there is no communication abnormality between the H site and the F site, and the probe request message of the D site not receiving the D site is caused by the communication abnormality between the F site and the D site, so The H site does not need to perform proxy change, and waits for the F site to perform proxy change completion. If the probe response message sent by the F site is not received within the N*T _BC timer time, there is communication between the H site and the F site. An exception, a proxy change is required.

本实施例的技术方案，STA站点在获知与PCO站点间存在通信异常时，发起代理变更的过程，从而保障数据通信，保证服务质量。In the technical solution of the embodiment, when the STA site learns that there is a communication abnormality with the PCO site, the process of proxy change is initiated, thereby ensuring data communication and ensuring service quality.
