Porkka XWEB HACCP monitoring
Porkka XWEB is an independent monitoring and alarm
warning control system for refrigeration equipment. XWEB is
a compact powerful computer that operates as an
independent network server complete with its own
ready-made web page. Information can be accessed either by
the internet, browser or a GPRS-enabled mobile phone.
Porkka can offer several versions to suit small to large
operators.
The XWEB allows 24/7 monitoring, controlling and adjusting
in real time. It continuously records temperature and alarm
data and will notify specific personnel of equipment failure.
The system can be accessed from any computer as software is
not required to gain entry to the programme.
Simple supervision
Compared to traditional, passive monitoring the Porkka
XWEB offers real time temperature monitoring and alarm
notification, which can be integrated within an existing BMS
(Building Monitoring System). Browser facilities enable access
for holders with a username and password at several levels if
required. Information distribution to all relevant personnel is
also quick and easy.
Reduced operating costs
Monitoring real time temperature data can give quick and
effective information on how a particular item of equipment
is being used. This in turn can allow the operator to control
the operation of the equipment more effectively and reduce
energy consumption. Maintenance personnel can also gain
valuable information from data, such as when servicing is
required. This also has the effect of reducing main component
failure which reduces overall running costs.
Intelligence = knowledge
Porkka XWEB allows the operator to use the refrigeration
equipment being monitored more effectively which is better
for the environment. The system can, for example, record door
openings (for devices fitted with a door switch), defrost cycles
etc. This in turn can highlight critical points in the operation of
the equipment, for example, when doors are kept open for
too long when goods are being received. After training,
energy cost can be reduced.
Device information
Within the Porkka digital temperature display is a
circuit board equipped with a TTL connection.
A RS485 adapter is available as an optional extra.
The control unit uses Modbus RTU data transmission
protocol. Items of refrigeration equipment are
connected to a Porkka XWEB computer (operating
system Linux). You may select from several models
which can monitor continuously up to 12 units, the
largest able to cope with up to 230 units. There are
also software solutions to cater for different
requirements.
A good idea is to digitally photograph each item of
equipment when installed, then the graphic user
interface can display real time information on the
equipment’s temperature and operation.
To connect to a network use a RJ-45 cable and
specify it to a fixed IP address. This will allow
continuous connection for several users. Smaller
users can connect the system to a telephone plug
via a modem, but only one user can access at any
one time.
