A one-person night shift under supervision: presence confirmed zone by zone
A solution for sites where one person works at night: periodic confirmation of presence at the workstation, information at the supervision point, and a response according to the site’s own procedure.
- 1person on the night shift
- 3types of site
- 1supervision point per site
01 / Investment context
What problem had to be solved?
At filling stations, loading centres and transit warehouses the night work is done by one person. They are alone on the site, and their work covers several zones. If they collapse or have an accident, nobody nearby will notice, and they may not be able to call for help themselves.
The site operator needs technical confirmation that the worker is at their post, and the ability to respond in line with the agreed procedure. Supervision by phone calls burdens both sides and leaves no record, and silence at night does not in itself mean that all is well.
The investor’s goal: One-person night staffing without giving up supervision: the worker confirms presence at intervals, and a missing confirmation triggers a response according to procedure.
What was designed?
In the installation the worker confirms presence at the workstation at intervals, and the information reaches the supervision point. The system can be adapted to the number of supervised zones, the work schedule and the response procedure in force at the site.
For a similar site GORKE today selects button-type checkpoints (SPR-PKP1), one in each zone, and a checkpoint transmitter (RNB-101/CK2) that the worker carries. Following the schedule, the worker checks in with it at the checkpoint, and the confirmation travels by radio to an identification receiver (IDO-1000) at the supervision point. Tablica Synoptyczna (SPA-1000/T) logs every confirmation with its time, so it is clear whether the next one arrived on time.
When nobody but the worker is on site at night, an SMS module (GSU-SP1000/L) sends the confirmations from Tablica Synoptyczna to the supervisor’s phone — no further message within the set time is the signal to respond. A pendant transmitter (SPR-P41) additionally lets the worker call for help with one press.
02 / Operating principle
From signal to action.
The night-shift worker confirms presence at intervals, and the supervision point sees whether the confirmations arrive on time.

Help does not depend on the worker making a call. A confirmation missing within the set time is the supervisors’ signal to respond according to the site’s procedure.

Devices for a similar investment
The description of the installation names no models — this is GORKE’s choice for a similar site.
SPR-PKP1
Button-type checkpoint fitted in each supervised zone: at the workstation, in the yard, in the warehouse.
Quantity: 1 per zone
IDO-1000
Identification receiver at the supervision point: identifies the transmitter and passes every confirmation to Tablica Synoptyczna. H2 module, memory for 1000 transmitters.
Quantity: 1
SPA-1000/T
Tablica Synoptyczna with a touch-screen computer at the supervision point: shows the latest confirmations and keeps an archive with the time of each one.
Quantity: 1
GSU-SP1000/L
SMS module for Tablica Synoptyczna, LTE: sends the confirmations to the supervisor’s phone when nobody is at the supervision point; up to 10 numbers.
Quantity: 1
Installation component
Buffered 12 V DC power supply with battery
Powers the receiver and the SMS module; the battery keeps them running during a mains failure. The computer running Tablica Synoptyczna then needs its own backup power.
Quantity: 1
SPR-P41
Pendant transmitter: the worker calls for help with one press, also between confirmations. Up to 800 m with an H2-module receiver.
Quantity: optional

04 / Value for the investor
What does this solution give you?
Worker safety
A confirmation missing within the set time is the signal to respond, so help does not depend on whether the worker manages to phone.
One-person staffing, still supervised
The site can run at night with one person, and the operator has a technical record of the presence confirmations from the whole shift.
Fitted to the site
The number of zones, the confirmation schedule and the response are set for each site — one way at a filling station, another at a transit warehouse.
05 / Before installation
What needs to be settled for a similar investment?
Before devices are chosen, what matters is the site’s conditions and how the system ties into the final installation.
Requirements to verify
- The number of zones, the checkpoint locations and the confirmation schedule for the night shift.
- Who responds to a missing confirmation and how — a call to the worker, a patrol, alerting the manager — and how quickly.
- Where the supervision point is — on site within radio range or elsewhere; in the latter case the information goes by text and mobile coverage is needed.
- Range from the farthest zone to the receiver: inside buildings and between racks a range test decides, and a repeater extends the range if needed.
- The solution supports the supervision procedure but does not replace a certified alarm system or a security company’s monitoring.
