8、安诺尼实时频谱分析仪二次研发的控制端点（Control Endpoint ）说明

Depending on its functionality each configuration block of the Aaronia-RTSA-Suite accepts control

commands for example the start/stop command. These commands are not addressed to a specific RTSA

block and will be processed from all RTSA blocks in the block graph configuration.

Following control HTTP PUT request(http://localhost:54664/control) will start all streaming related

blocks at the remote configuration site. To stop the streaming the value of start needs to be set to false:

{

"start" : true, "type" : "streaming"

}\n'

Sending a put request is problematic using a web browser, but can be done using e.g. “curl” as a

command line tool.

curl -X PUT -d "{\"start\":false, \"type\":\"streaming\"}"

http://localhost:54664/control

To set the frequency range of the measurement devices, following fields are used:

{

"frequencyCenter" : 1200000000,

"frequencySpan" : 44000000,

"frequencyBins" : 448,

"referenceLevel" : -20,

"type" : "capture"

}\n'

Using curl:

curl -X PUT -d "{\"frequencyCenter\":1920.0e6, \"frequencySpan\":200.0e6,

\"type\":\"capture\"}" http://localhost:54664/control

An alternative way would be to specify the start and end frequency.

{

"frequencyStart" : 75.0e6,

"frequencyEnd" : 6000.0e6,

"type" : "capture"

}\n'

To start or stop the autorotation of all antennas in the remote block graph configuration, following fields

are used:

{

"rotate" : true,

"type" : "antenna"

}\n'

To start a record, following fields are used:

{

"start" : true,

"filename" : “xy”

"type" : "recording"

}\n'

To save or reload the running mission, following fields are used:

{

"save" : true, "type" : "mission"

}\n'

{

"reload" : true,

"type" : "mission"

}\n'

Configuration Data

Server Info

The “/info” endpoint provides information of the http server block, such as name, title, port, features

and the name and path of the mission http://localhost:54664/info.

{

"name" : "Block_HTTPServer_0",

"title" : "HTTP Server",

"uuid" : "aaf2a8f7-11fa-45a3-bcfc-26aaf5957629",

"port" : 54664,

"mission" : ""

}

General

All configuration items visible in the configuration blocks of the Aaronia-RTSA-Suite have a

representation as JSON. The list of available configuration items can be queried with the

“/remoteconfig” endpoint http://localhost:54664/remoteconfig.

The resulting JSON looks like this.

{

"request": 0,

"config": {

"type" : "group",

"name" : "remoteconfig",

"label": "RemoteConfig",

"items": [{

"type" : "group",

"name" : "Block_FileReader_0",

"label": "File Reader",

…

The configuration data forms a tree with the root being placed into the config member of the top-level

object. The second tree level is populated with the blocks of the graph, all further levels by configuration

elements of these blocks.

All config items share the following fields:

Leaf nodes carry configuration data, internal nodes have the type “group” and contain their child nodes

in a member named “items”. Leaf nodes provide their current value in the member “value” and the

default value in the member “default”.

Leaf Node Metadata

The following members can be found in leaf nodes and provide meta data.

All configuration items visible and editable in a configuration block of the Aaronia-RTSA-Suite can be

changed via the “/remoteconfig” endpoint and a HTTP PUT request. Each configuration block has a

unique name in a Aaronia-RTSA-Suite mission. This name is used to address a specific RTSA block. The

unique name for each RTSA block is provided in the response of the “/remoteconfig” HTTP GET request

and is static in an unchanged mission. Each “/remoteconfig” HTTP PUT request will be answered with the

same response a HTTP GET request will initiate.

A JSON “/remoteconfig” HTTP PUT request starts with the following fields:

{

"request" : 0,

"config" : {

"type" : "group",

"name" : "Block_Spectran_0",

"items" : [ {

…

A HTTP PUT request to enable the amplifier of a Spectran V5 RTSA block for example, looks like the

following:

{

"request" : 1, "config" : {

"type" : "group",

"name" : "Block_Spectran_0",

"items" : [{

"type" : "group",

"name" : "main",

"label" : "Main",

"items" : [{

"type" : "bool",

"name" : "amplifier",

"value" : true

}]

}]

}

}
