Because data transmission is carried out between the existing radiation measuring instrument and the data receiver through an RS485 or RS232 interface, the number of devices managed by an RS485 protocol is limited, and the RS485 transmission distance is limited. Therefore, the embodiment of the invention provides a data transmission method for a radiation measuring instrument, which aims to solve the problems in the prior art.
Fig. 1 is a schematic flow chart of a data transmission method for a radiometer according to an embodiment of the present invention, as shown in fig. 1, the method includes:
s11, acquiring a data packet sent by a radiation measuring instrument, wherein the data packet is obtained by packaging radiation data acquired by the radiation measurement into an Ethernet protocol, a data source of the radiation data is an address of the radiation measuring instrument, and a target address of the radiation data is an address of a remote server;

and S13, processing the data packet based on the tunnel address, and sending the processed data packet to a remote access device, so that the remote access device forwards the processed data packet to a remote server.
Specifically, in the data transmission method for a radiation measuring instrument provided in the embodiment of the present invention, the execution main body is a radiation measuring instrument Access device, where the radiation measuring instrument Access device is an Access device configured on one side of the radiation measuring instrument, and the Access device may also be referred to as a Client Access Point (CAP) and is configured to acquire a data packet sent by the radiation measuring instrument, process the data packet, and transmit the processed data packet to a remote Access device through the internet. A virtual access device CAP (i.e., a vCAP) may be deployed in a public cloud of the internet, and is used to establish an encryption channel with physical CAPs such as a radiation measurement instrument access device and a remote access device, where the vCAP includes an external network and an internal network, and a virtual server is deployed in the internal network, and server software for receiving, storing, and displaying data is installed. The CAP and the vCAP are intercommunicated on the Internet channel through a vxlan over IPSEC encryption algorithm. The radiation measuring instrument can dynamically acquire a private network IP address through the radiation measuring instrument end CAP and configure a remote server intranet address.
Any CAP and other CAPs are directly interconnected through an encryption tunnel, one or more internal subnets can be connected inside each CAP, and the internal networks in all CAPs can be configured to be not intercommunicated at all or to be intercommunicated among designated subnets. The monitoring software of the radiometer may be deployed anywhere in the network. In order to avoid the failure of data packet transmission caused by single network failure, a wired network and a 4G/5G wireless network can be dynamically selected in the CAP to transmit data.
The remote access device is an access device CAP on the side of the remote server, and the access device is used for receiving the data packet sent by the access device of the radiation measuring instrument, processing the received data packet and forwarding the processed data packet to the remote server. In the embodiment of the invention, the remote server can be a monitoring server, and monitoring software can be deployed on the remote server so as to realize the monitoring function of the radiation measuring instrument according to the processed data packet. In the embodiment of the invention, each CAP can be configured with a wired and 4G/5G dual uplink port, and when a wired link fails, the data can be dynamically adjusted to a 4G/5G link for data transmission.
First, step S11 is executed, and the CAP acquires a data packet sent by the radiometer. Before the data packet is obtained, the radiation data is collected by the radiation measuring instrument, then the radiation data is directly packaged into the Ethernet protocol, and finally the obtained data packet is sent to the CAP. The Ethernet protocol may be an Ethernet TCP/UDP protocol. In the packaging process, the data source of the specified radiation data is a local address, namely a radiation measuring instrument address, and the target address of the specified radiation data is a remote server address, namely an address of a server in a remote subnet.
Then, step S12 is executed to determine the tunnel address of the remote access device corresponding to the radiation data according to the target address. The determining means may be that the local server of the CAP stores a corresponding relationship between the target address and the tunnel address, and then determines the tunnel address of the remote access device corresponding to the radiation data by combining the target address of the radiation data in step S11.
And finally, executing the step S13, processing the data packet according to the tunnel address determined in the step S12, and then sending the processed data packet to the remote access equipment so that the remote access equipment forwards the processed data packet to the remote server. The processing of the data packet according to the tunnel address may include adding a tunnel header to the radiation data according to the tunnel address, and encrypting the radiation data. The encryption may be implemented by using a vxlan over IPSEC encryption algorithm, or may be implemented by using other encryption algorithms, which is not specifically limited in the embodiment of the present invention.

In the embodiment of the invention, the service load can be shared by deploying a plurality of remote servers, so that the number of the managed equipment can be greatly increased to hundreds, thousands or tens of thousands. In addition, the embodiment of the invention carries out data transmission through the Ethernet protocol, can transmit radiation data in a park and also can transmit the radiation data on the Internet, and is not limited by distance.
Because data transmission is carried out through the RS485 or RS232 interface, cables need to be deployed, the construction time is long, and the cables are deployed in an external mode, so that the appearance is affected, and the method is unsafe. Therefore, in the embodiment of the present invention, when the radiometer sends the data packet to the CAP, the data packet may be sent in a wired communication manner or a wireless communication manner. The wired communication mode may be implemented by RJ45 network cable, and the wireless communication mode may be implemented by wifi signal, which is not specifically limited in the embodiment of the present invention.

As can be seen from table 1, the destination address is denoted by CIDR, and a plurality of destination addresses may correspond to a tunnel address of the remote access device to which the radiation data corresponds. The purpose of the query in the first DB is to determine whether a tunnel address corresponding to the target address is stored in the first DB. If the query result of the first DB is not null, it is indicated that the first DB stores the tunnel address corresponding to the target address, and the query result of the first DB is the tunnel address. And if the query result of the first DB is null, the remote access equipment corresponding to the radiation data is indicated to be wrongly configured, the data packet is directly discarded, and an error log is recorded.

The purpose of querying in the second DB is to determine whether the tunnel address of the remote access device corresponding to the radiation data has a corresponding exit address and link quality in the second DB, and may select a target link with better link quality, i.e. a target tunnel. That is, when the query result of the second DB is not empty, the query result of the second DB is the target tunnel with the better exit address and link quality.
And then, encapsulating the target tunnel according to the inquired exit address, and sending the processed data packet to a remote server through the target tunnel.

Specifically, in the embodiment of the present invention, after the query is performed in the second DB according to the tunnel address, if the query result of the second DB is empty, that is, if there is no target link with good link quality in the second DB, it indicates that the link quality of all links corresponding to the link address in the second DB is in the interrupted state, the query is performed in the third DB according to the tunnel address, and the third DB stores the correspondence between each tunnel address and the transit tunnel address, the egress address, and the link quality, and the correspondence is usually stored in the third DB in the form of a table, as shown in table 3. Each radiation measuring instrument end CAP can establish a tunnel with a plurality of remote end CAPs, when a certain tunnel detects a fault, the tunnel can be dynamically transferred through other CAPs, and at the moment, the tunnels of other CAPs are transfer tunnels.
TABLE 3 correspondence between tunnel addresses and transit tunnel addresses, egress addresses, and link quality
| Tunnel address | Transit tunnel address | Egress address | Link quality |
| AAAA | BBBB | XXXX | 80ms/5％/10ms |
| BBBB | AAAA | YYYY | 80ms/5％/10ms |
The purpose of querying in the third local database is to determine whether the tunnel address has a corresponding transit tunnel address, an egress address, and a link quality in the third DB.
And if the query result of the third DB is not null, the query result of the third DB is that the transit tunnel address, the exit address and the link quality corresponding to the tunnel address are stored in the third DB. And then, encapsulating the transit tunnel according to the inquired exit address, and sending the processed data packet to a remote server through the transit tunnel.
And if the query result of the third DB is empty, namely the query result of the third DB is that the third DB has no transit tunnel address, exit address and link quality corresponding to the tunnel address, indicating that the configuration is wrong, directly discarding and recording an error log.
In the embodiment of the invention, when the link quality of all links corresponding to the link address is in the interruption state, the processed data packet can be sent to the remote server through the transit tunnel address, so that the normal sending of the processed data packet is ensured. Moreover, the exit address and the transit tunnel are determined by inquiring the third DB, so that the obtained exit address and the transit tunnel are more accurate, and the determination process is simpler.
