Description

The present invention relates to a method for autonomous danger monitoring in a construction site area and / or a traffic area adjacent to the construction site area. The present invention further relates to a corresponding device and a construction site vehicle having such a device or is adapted to carry out such a method.

Due to the maintenance, renewal and transformation of the transport infrastructure, there are often construction sites, especially for road traffic. Since decommissioning of road traffic in the construction site area is usually not possible, usually a construction site bypass for moving road users is established. The construction site bypass usually uses a traffic area directly adjacent to the construction site area. So multi-lane roads are often set up for one or more tracks construction sites and closed off for the road users and used the remaining tracks to guide the road users at the site over. This results in a threat to both the construction workers working on the site by passing vehicles as well as for the construction site passing vehicles by construction workers or construction machinery. For example, construction workers need to focus on their construction work and can not, in parallel with their work, perceive any potential hazards arising from passing traffic, especially on heavily frequented roads and highways, and react to it in a timely manner. This applies all the more in poor visibility or tiredness of construction workers, especially if the construction site is also operated at night. Despite measures to secure the construction site as the signs of construction sites, it is therefore time and again to fatal accidents involving personal injury.

A facility for monitoring, checking and alerting endangered goods and persons, both with regard to the operational safety of technical equipment, and the protection of persons and facilities against access by unauthorized third parties, shall be provided by DE 100 59 952 A1 disclosed. Here it is proposed to accommodate a command center in a vehicle and to occupy with a surveillance engineer. Monitoring and documentation devices, communication and information devices and sensors are provided in, on or outside the vehicle. The communication and information facilities serve to communicate the surveillance engineer with field offices. This system can also be used for monitoring or securing a construction site.

It is an object of the invention to provide an improved method for autonomous danger monitoring in a construction site area and / or a traffic area adjacent to the construction site area, a corresponding device and a corresponding construction site vehicle.

This object is achieved by a method having the features of claim 1, a device according to claim 10 and by a construction vehicle according to claim 11. Preferred embodiments of the invention are the subject of the dependent claims.

In the method according to the invention for autonomous danger monitoring in a construction site area and / or a traffic area adjacent to the construction site area, data is exchanged with one or more traffic objects located in the construction site area and / or the traffic area adjacent to the construction site area. The exchanged data is evaluated centrally and a potential hazard of one or more of the traffic objects is determined. Based on the result of the central evaluation, a measure to avoid danger is taken.

As a result of the monitoring of the traffic objects, a danger situation is recognized early on and a potential hazard by a suitable measure for avoiding danger is reduced. Thus, in addition to the construction site, the passing traffic can also be monitored and a potentially present hazard can be identified at an early stage for traffic objects located in the transitional area. This also makes it possible to reduce the extent of signage in the construction site area or even barriers and to optimize workflows on the construction site and the traffic flow in the adjacent traffic.

According to one embodiment of the invention, the traffic objects in the construction site area are, in particular, construction machines or construction workers, and the traffic objects in the traffic area adjacent to the construction area, in particular, the construction site area shortly or currently passing vehicles.

Preferably, a warning is generated and output to avoid danger.

In this case, the warning may concern a hazard in the construction site area by vehicles in the traffic adjacent to the construction site area.

Likewise, the warning may concern a hazard to a vehicle in traffic adjacent to the construction site area due to hazards arising from the construction site.

According to one embodiment of the invention, one or more parameters concerning a traffic object are received by the traffic object.

According to a further embodiment of the invention, parameters relating to a traffic object are detected by sensors.

Advantageously, parameters of the traffic objects, which relate to the position and / or speed and / or direction of movement and / or target position of the respective traffic objects, are evaluated and from this the probability of a potential hazard is determined.

• - Vitalfunktionen der Bauarbeiter;
• - Tätigkeiten der Baumaschinen oder Bauarbeiter;
• - Verkehrssituation und/oder Gefahrenpotential auf der Baustelle;
• - Sicherheitsaspekte der Baustelle.

Furthermore, in the case of traffic objects in the construction site area, instead of or in addition, detection and / or monitoring of one or more of the following parameters may take place:

• - Vital functions of construction workers;
• - activities of construction machinery or construction workers;
• - Traffic situation and / or danger potential on the construction site;
• - Safety aspects of the construction site.

Correspondingly, a device according to the invention for autonomous danger monitoring in a construction site area and / or a traffic area adjacent to the construction site area comprises a communication unit for exchanging data with one or more traffic objects located in the construction site area and / or the traffic area adjacent to the construction site area. Furthermore, the device has an evaluation unit which centrally evaluates the exchanged data and determines a potential hazard of one or more of the traffic objects. By means of a danger prevention unit, a measure for avoiding danger is taken based on the result of the central evaluation.

The invention also relates to a construction vehicle in which the method according to the invention or the device according to the invention is used.

Here, the construction site vehicle may comprise a display unit arranged on the outside, on which a warning is given to the traffic objects.

Furthermore, the construction site vehicle can be set up so that it travels autonomously to a danger location in order to secure it on site by visual and / or acoustic signals.

For a better understanding of the principles of the present invention, embodiments of the invention will be explained in more detail below with reference to the figures. It should be understood that the invention is not limited to these embodiments, and that the features described may also be combined or modified without departing from the scope of the invention as defined in the claims.

1 schematically shows an overview of an autonomous danger monitoring of several in a construction site area or an adjacent to the construction area traffic area located traffic objects. An autonomously operated construction vehicle, also referred to below as a construction site command vehicle ABKF designates, monitors the various in the construction site area B located transport objects, exemplified in the figure by a construction machine 1 and a construction worker 2 shown. Under construction machines are understood in particular semi-mobile or mobile machines that are powered by internal combustion engines or electric motors and with which, for example, processed and processed building materials, building aids transported and construction tasks can be performed.

The autonomously operated construction site command vehicle ABKF is networked with the transport objects through a suitable communication method such as the car-to-X communication technology, so that an exchange of information such as activities of construction equipment and vital functions of construction workers is possible. In the same way is the autonomously operated construction site command vehicle ABKF also with traffic objects in the environment U networked the construction site, exemplified in the figure by a road vehicle 3 and a civilian 4 shown. The networking with the various traffic objects and the central evaluation and management of the exchanged data then makes it possible to recognize a potential danger in good time and to initiate suitable measures, such as issuing a warning to the traffic objects concerned.

2 shows a flowchart of a method according to the invention for autonomous danger monitoring. In a first process step 5 Data is exchanged with one or more traffic objects located in the construction site area and / or the traffic area adjacent to the construction site area. In this case, parameters such as, for example, the respective current location, a future destination position, or else the type of activity performed, are transmitted by the traffic objects to a central evaluation unit. The central evaluation unit can in this case in particular in a construction vehicle, such as the above-mentioned autonomously operated construction site command vehicle ABKF , and be part of a mobile device or even permanently installed in the construction vehicle. The received data are in a second process step 6 centrally processed to check whether there is a potential threat to one or more of the traffic objects. If it is determined here that a potential danger exists, for example, through a collision of two traffic objects, then in a third method step 7 taken a measure to avoid danger. Thus, a warning about the hazard can be issued. The warning can only be issued to the traffic objects at risk, but also to all traffic objects located in the construction site area and / or the traffic area adjacent to the construction site area.

The warning can be reproduced in different ways. Thus, the data containing the warning, in particular the nature, position and / or removal of the potential hazard, are transmitted to the traffic objects and there visually, acoustically or haptically issued to the people involved. For example, a warning may be displayed on construction vehicles or on the construction site passing vehicles on a display. Likewise, via loudspeakers connected to a radio or infotainment system of a vehicle, an acoustic warning, in particular by a voice output describing the hazard, can take place. For on-site construction workers, for example, offers a haptic warning by a wearable device, such as an electronic wristwatch (also known as smartwatch), as such a warning without regular control of any successful displays and also at high level of noise can be perceived immediately.

In this case, it can be provided that information about the status or degree of the current risk of danger is continuously transmitted to the traffic objects. Furthermore, also possible alternatives, for example, to use a different lane, can be specified. Likewise, an information can be sent to the all-clear, if the potential danger no longer exists.

In the exemplary embodiment, in which the monitoring and emission of warnings by an autonomously operated construction site command vehicle ABKF further action may be taken if the traffic objects do not appear to respond to the warning. So can in a fourth process step 8th the construction site command vehicle ABKF Drive autonomously to the danger point to protect it on site by visual and / or acoustic signals.

A schematic representation of an autonomous construction site command vehicle according to the invention ABKF with an indication of a warning is in 3 shown. There is at least one display on the outside 9 intended. In this case, only a single display may be present, which is arranged on one side of the construction site vehicle, or also extends circumferentially over several sides of the construction site vehicle, but it is also possible for a plurality of displays to be provided on the various vehicle sides. The autonomous construction site vehicle is then positioned depending on the arrangement of the display displays on the vehicle, the spatial conditions in the construction site area and / or adjacent to the construction area traffic area and possibly the direction of travel of the vehicles in the adjacent traffic area so that they are well perceived by the affected transport objects is.

An indication of a warning on the side of the construction vehicle is in 3a displayed. Here, in addition to a warning "construction site warning" in addition to a call "brakes" to the affected vehicles output. If the space is not sufficient to position the autonomous construction site laterally, for example, when positioning on the Pannenstreifen or a terminating lane, so a corresponding display can also be done on the front or rear side of the construction vehicle. As in 3b shown, this can also be a two-part display, which in addition to a request "brakes" another call for "lane change" reflects.

A use of an autonomous construction site vehicle according to the invention ABKF in a closed construction site area B is in 4 shown. The traffic objects monitored by the autonomous construction site vehicle in the form of construction machines and construction workers are each located in a separate work area, in the present example, three construction machines in the separate work areas 10 and three construction workers, each in a separate workspace 11 supervised. Through radio links between the construction machinery and construction workers with the autonomous construction site vehicle data are transmitted to the autonomous construction vehicle and evaluated in this centrally. The autonomous construction vehicle then transmits warnings or calls for action back to the construction machinery and construction workers. If necessary, the autonomous construction vehicle can also change position and, for example, move to an endangered traffic object in order to improve the perception of the warnings.

Finally shows 5 a use of an autonomous construction site vehicle according to the invention ABKF to monitor traffic objects in an open construction site area. A construction site B takes only the right lane of a multi-lane road and the adjacent Pannenstreifen P while the remaining lanes can still be used by public roads. Immediately before the start of the construction site, the right-hand traffic lane is blocked by suitable measures, such as beacons, for passing vehicles at the construction site 3 to cause a lane change on one of the lanes not affected by the construction site. The autonomous construction vehicle exchanges data with the construction machines on the construction site 1 and construction workers 2 as well as with passing vehicles at the construction site 3 out. A potential threat to a traffic object may be present here, for example, in the form of an imminent collision, which is determined from position data and the anticipated movement trajectories of the monitored traffic objects determined therefrom. For example, the road traffic passing by the construction site may be warned when a slow moving construction machine leaves the construction site and drives on a lane used by the passing road traffic or is to be feared due to a malfunction that an autonomous construction machine unintentionally moves the construction site in the direction of the used lanes leaves.

The autonomous construction site vehicle is outside of the construction site on the unused road traffic on public roads P and can autonomously change the position in the puncture strip. Thus, the autonomous construction vehicle can take a position in confusing road conditions, which allows an early warning of a hazard. For example, at a construction site located behind a curve or a crest of the roadway, the autonomous construction site vehicle can autonomously drive in front of the curve or crest of the roadway and deliver warnings to vehicles approaching the construction sites. Likewise, the autonomous construction vehicle can detect the speed of the approaching vehicles. For example, the speed of successive position data that these vehicles determine by means of existing GPS modules and transmitted to the autonomous construction vehicle or by the use of suitable sensors of the autonomous construction site vehicle, such as radar sensors, are determined. If it is concluded from the determined data that there is a danger to the construction workers or construction machines in the area of the construction site due to an approaching vehicle, for example due to a significantly excessive speed, the construction site vehicle can also be used to warn the construction workers and construction machines.

In another embodiment, based on the autonomous construction vehicle ABKF recorded or supervised vital functions of the construction workers a health and recovery program are carried out for them. Give the collected and evaluated Biovital data, such. B. plus frequency, skin moisture, body temperature, skin conductance; Blood sugar, etc., which can be detected both invasively or non-invasively, for example, the construction worker over fatigue or overexertion, so a suitable health and recovery program can be created. In the autonomous construction vehicle ABKF can be provided for a corresponding treatment area or rest area. Exemplary applications or health programs here are the observance of rest recommendations or maximum outdoor living times for sun protection, massage treatments for strong or one-sided physical activities, heat treatments in cold weather, light therapy, oxygen therapy, etc. Some of these applications, such as. Massage and heat treatments may be provided by one or more appropriately equipped seats in the autonomous construction vehicle ABKF be implemented. Since the construction workers work in a more concentrated and careful manner after such a recovery phase, this can also contribute to safety or avoidance of danger.

The invention is not limited to the autonomous monitoring of danger in road traffic, but can be used in any areas of traffic engineering, such as in construction sites in rail transport.
