gt; npm install @agilatech/zetta-rmy85000-linux-driver
OR

var zetta = require('zetta');
var rmy85000 = require('@agilatech/zetta-rmy85000-linux-driver');
zetta()
.use(rmy85000, [options]) // where [options] define operational paramters -- omit to accept defaults
.listen(<port number>) // where <port number> is the port on which the zetta server should listen
These options are defined in a file named 'options.json' which may be overridden by program definitions
"file":"<serial file device>"
/dev/ttyS0, /dev/ttyO2, etc... Defaults to /dev/ttyS0
"chronPeriod":<period>
Period in milliseconds for monitored isochronal data
"streamPeriod":<period>
Period in milliseconds for streaming data. A value of 0 disables streaming.
Agilatech has definied the open port number 1107 as its standard default for IIOT (Industrial Internet Of Things) server application. In practice, most any port above 1024 may be used by other organizations.
Using directly in the zetta server:
const zetta = require('zetta');
const sensor = require('@agilatech/zetta-rmy85000-linux-driver');
zetta().use(sensor).listen(1107);
Initializes the rmy85000 driver on serial device /dev/ttyS0 with a data monitoring period of 60 seconds and streaming data every second.
To override the options defined in the options.json file, supply them in an object in the use statement like this:
zetta().use(sensor, { "file":"/dev/ttyS2", "chronPeriod":30000, "streamPeriod":15000 });
Overrides the defaults to initialize the serial device on /dev/ttyS2 with a data monitoring period of 30 seconds and streaming data every 1.5 seconds
All drivers contain the following 5 core properties:
In the chron-on state and active operation, the driver software for this device monitors FIXME values in isochronal fashion with a period defined by chronPeriod:
If the hardware is active, the driver software continuously streams FIXME values with a frequency defined by streamPeriod. Note that a streamPeriod of 0 disables streaming.
chron-off is the beginning state. The driver also enters this state after a transition 'stop-isochronal' command.
In this state, all monitored data values are set to 0, and no sensor readings are updated.
chron-on is the state after a transition 'start-isochronal' command. In this state, all monitored data values are updated every time period as specified by 'chronPeriod'.
This device driver is designed for both streaming and periodic monitored data collection from the RM Young 85000 series ultrasonic anemometer. The hardware measures wind speed from 0-60 m/s with an accuracy of ±0.1 m/s. Wind direction is measured from 0-360 degrees with an accuracy of ±3 degrees.
Wind speed and direction values are instantaneous, with no averaging or time weighting performed. Any analysis of averages and gusts will need to be performed downstream of this driver.
The hardware interfaces via RS-232 or RS-485, so your hardware must support one of these protocols. The serial device file can be specified in the constructor.
