autoware_velodyne_monitor

Purpose

This node monitors the status of Velodyne LiDARs. The result of the status is published as diagnostics. Take care not to use this diagnostics to decide the lidar error. Please read Assumptions / Known limits for the detail reason.

Inner-workings / Algorithms

The status of Velodyne LiDAR can be retrieved from http://[ip_address]/cgi/{info, settings, status, diag}.json.

The types of abnormal status and corresponding diagnostics status are following.

Abnormal status	Diagnostic status
No abnormality	OK
Top board temperature is too cold	ERROR
Top board temperature is cold	WARN
Top board temperature is too hot	ERROR
Top board temperature is hot	WARN
Bottom board temperature is too cold	ERROR
Bottom board temperature is cold	WARN
Bottom board temperature is too hot	ERROR
Bottom board temperature is hot	WARN
Rpm(Rotations per minute) of the motor is too low	ERROR
Rpm(Rotations per minute) of the motor is low	WARN
Connection error (cannot get Velodyne LiDAR status)	ERROR

Parameters

Node Parameters

Name	Type	Default Value	Description
`timeout`	double	0.5	Timeout for HTTP request to get Velodyne LiDAR status [s]

Core Parameters

Name	Type	Default Value	Description
`ip_address`	string	“192.168.1.201”	IP address of target Velodyne LiDAR
`temp_cold_warn`	double	-5.0	If the temperature of Velodyne LiDAR is lower than this value, the diagnostics status becomes WARN [°C]
`temp_cold_error`	double	-10.0	If the temperature of Velodyne LiDAR is lower than this value, the diagnostics status becomes ERROR [°C]
`temp_hot_warn`	double	75.0	If the temperature of Velodyne LiDAR is higher than this value, the diagnostics status becomes WARN [°C]
`temp_hot_error`	double	80.0	If the temperature of Velodyne LiDAR is higher than this value, the diagnostics status becomes ERROR [°C]
`rpm_ratio_warn`	double	0.80	If the rpm rate of the motor (= current rpm / default rpm) is lower than this value, the diagnostics status becomes WARN
`rpm_ratio_error`	double	0.70	If the rpm rate of the motor (= current rpm / default rpm) is lower than this value, the diagnostics status becomes ERROR

Config files

Config files for several velodyne models are prepared. The temp_*** parameters are set with reference to the operational temperature from each datasheet. Moreover, the temp_hot_*** of each model are set highly as 20 from operational temperature. Now, VLP-16.param.yaml is used as default argument because it is lowest spec.

Model Name	Config name	Operational Temperature [℃]
VLP-16	VLP-16.param.yaml	-10 to 60
VLP-32C	VLP-32C.param.yaml	-20 to 60
VLS-128	VLS-128.param.yaml	-20 to 60
Velarray M1600	Velarray_M1600.param.yaml	-40 to 85
HDL-32E	HDL-32E.param.yaml	-10 to 60

Assumptions / Known limits

This node uses the http_client and request results by GET method. It takes a few seconds to get results, or generate a timeout exception if it does not succeed the GET request. This occurs frequently and the diagnostics aggregator output STALE. Therefore I recommend to stop using this results to decide the lidar error, and only monitor it to confirm lidar status.
