Sensor technology for object and person recognition

24.09.2021: Sensotek from Ebersbach in Swabia, a subsidiary of Pepperl+Fuchs SE, announced at today's press event that Only one security system presented. The unique system is used to separate, count or recognize the direction of people and groups of people. It ensures extremely reliably that people are isolated, counted or checked for their direction of movement when they pass the sensor.

Isolation of people

The Personal control ensures that only one person z. B. one for each ID card or ticket Access control or pass through the lock. Thanks to the stored algorithms, an individual can successfully pass the facility regardless of their stature and body size. For example, if she is carrying a suitcase or backpack, entry will be denied. Two or more people and objects are also recognized and can be reliably rejected. Typical applications can be found in security locks such as in data centers, banks, military security facilities and others

Counting people

The Only One resp. Every sensor counts also recognizes individuals or groups of people in opposite directions. The counting is carried out according to their direction of travel. The evaluation can take place according to count values. The counter Sensor but can also be used for quick separation. Typical applications are revolving doors in airports, open passageways, lattice revolving doors to secure the area outside, ticket control systems on railways and lifts as well as general people counting in all door and passageway areas.

Direction recognition of people

When detecting the direction is only forward hip, trendy, popular. Only One detects people moving in the opposite direction or turning around and reports them reliably and securely - regardless of whether people or objects are detected, the wrong direction of movement is decisive. A typical application is the entry control in airports in the one-way corridors.

Cell free detection and manipulation

What all applications have in common is recognition Cell free. Only One always reports the occupied status of the cell, regardless of the persons recognized. If, for example, a piece of luggage is left in a separation system, this is safely reported. This information can be used to block access systems or to issue an alarm. The occupancy detection of cells and areas is implemented reliably and without any additional sensors.

Admission control by cameras with people counting function

The sensor recognizes Attempted manipulation in the form of sabotage by covering the sensors. Based on the principle of distance measurement with Time-Of-Flight (TOF) technology, the sensors create a 3D height profile in plan view. This is qualified with the AI-based analysis logic integrated in the sensor and is evaluated using this.

Real ones emerge from this Shape and spacing informationthat deliver the results required by the application, practically independent of external light or surface influences. All evaluations run internally in the sensor. Only the finished result is transmitted.

GDPR-compliant personal control

The only one system is used for all recording GDPR compliant. At no time are data recorded that allow a person to be identified as an individual. The person recognition consists of at least one 3D TOF sensor, which is always installed with a view from above. This means that there are no optically or mechanically annoying additions to the wall or floor, and the use of glass walls and glass doors is not impaired.

Additional equipment such as step mats, scales or other sensors are not required. Floor coverings also do not influence the evaluation. The system also requires no additional lighting and even works in total darkness. CAN and Ethernet interfaces are available.

Converter box for retrofitting

Only one converter box The Only One Sensor can replace existing sensors in the retrofit area or upgrade previously less secure systems. Digital I / Os are available potential-free or as semiconductor outputs as interfaces. Individual adjustments to the signals supplied by the sensor can also be implemented.

Access control with human counters for retail

This person control is therefore a simple, compact and reliable way of identifying new and existing doors, access and Gate systems with one noticeably increased safety factor without having to intervene in the existing mechanics. The extremely low installation height of at least 1,90 m is also suitable for difficult applications where other systems fail. The sensor can be built in and has a visually appealing design. The construction depth is only a few centimeters, so the system disappears inconspicuously into the ceiling.

The one integrated in the 3D TOF principle Infrared illumination makes the sensor extremely insensitive to surface properties and external light influences. This significantly reduces errors and malfunctions. Service and support are of course also given.

Digital admission control for exact counting of people

31.07.2020: The Corona Pandemic has spurred numerous government actions over the past few months, including the limited number of people in public facilities. Sensotek presents with the Smart Entrance Manager digital admission control for highly accurate people counting.

The Smart Entrance Manager is the first entry control System solution in a modular system. The entrance control was designed, among other things, to control the entrance of people present in shops or other rooms for retailers, retailers, beverage markets, shoe stores or hardware stores. The development of these digital admission controls is based on Sensotek's many years of know-how in the field of door automation.

"We now all know the employees in the hardware store who give us shopping trolleys in order to limit the number of people in the store with regard to legal requirements," says Rainer Niess, CEO of Sensotek. "I predict that in six months' time the picture of people counting will be part of retail, wholesale, gas stations, town halls and so on."

Admission control has so far only been difficult to implement

An exact count by humans is usually difficult or can be implemented with high personnel costs. The digital admission control from Sensotek now offers based on the Time-of-flight technology (TOF) an accuracy of the people counting greater than 99%. Admission control counts people passing through with directional evaluation. It can be configured for simple people counting with evaluation of an entrance and exit door or for more complex access controls at several entrances and exits.

"With our digital admission control, the current regulations on the corona pandemic can be monitored. According to the size of the facility, the user stores the maximum number of people in the system. “The Smart Entrance Manager counts the people in the facility with each person entering and leaving the facility until the specified limit is reached,” says Rainer Niess, describing the function.

The 3D-TOF sensor is not influenced by environmental influences such as temperature and incidence of light, as is the case with other commercially available sensors for people counting. Rather, the time-of-flight sensor evaluates real distance and shape information and recognizes people based on their shape and movement.

Easy installation and adjustments on site

When installing the system for digital admission controls, the components are simply over Ethernet Cables connected together. The interface developed by Sensotek switches the sensors in the outdoor area above the automatic door as soon as the specified number of visitors is exceeded. With the completely self-sufficient system, no more people can enter the sales rooms, but they can still get outside safely.

Inductive sensor with a reliably high switching distance

The user accesses the control display via Finger pressure and Pin entry to the settings. Here he enters the maximum number of people allowed. The display informs about a traffic light man in green or red whether admission to the public facility is still granted or whether it is temporarily not allowed to be entered.

An SD card In the control, the evidence against official controls is secured by backing up counted values. The admission control is 100% data protection compliant according to the GDPR. Access is via a mobile device in an app with remote control function.

Ampelmännchen informs about access

“We are currently the only provider on the market to offer such a complete system that consists of one Construction kit put together. Our Smart Entrance Manager thus offers the right solution for every application, ”comments the managing director.

Even a museum in a tower or a narrow spiral staircase would not be a challenge for this entry control. "The Traffic light control In conjunction with the digital people counting system, it also prevents people from meeting on the narrow staircase. That is a big difference to the other market providers, ”notes Mr. Niess.

The output screen shows the number of people who are in the facility. One green and one red Traffic light man informs the visitor whether the room can be entered.

At the same time, when the max. Block the entrance to the permitted number of visitors by switching off the external detector on the automatic door. If necessary, a App which, with the same network of control and mobile device, also reports the number of people on a smartphone or tablet.
