DE102020000861A1 - Mobile and self-sufficient cloud video surveillance mast - Google Patents

Abstract

The invention is used for the active prevention / monitoring of criminal offenses through intelligent IP security technology, which is managed based on the cloud, in areas that do not have a technical infrastructure. The mast is designed in such a way that it can be brought to the installation site, assembled and erected by 2 people without crane technology. An off-grid photovoltaic system, which consists of two bifacial photovoltaic modules, a charge controller, a battery monitor and two solar batteries, is used for the self-sufficient power supply. The power supply is designed for approx. 3 days at. Communication is ensured through network-independent mobile Internet access. The IP surveillance technology with intelligent video analysis and the management of this hardware via a cloud service make it possible to proactively protect the monitored areas. The user / security guard has the possibility to recognize intruders through a secure detection and to make them flee by live remote address via the mobile device on site or the Internet browser.

Description

State of the art:

Video surveillance masts for mobile surveillance are already available in various designs. The completely self-sufficient use of these masts with the inclusion of cloud technology for the configuration and maintenance of the technical components is not yet possible.

Problem:

The invention specified in claim 1 is based on the problem of enabling an active prevention of criminal offenses by means of IP surveillance cameras regardless of the installation location and time of day. Conventional mobile masts have so far only been used to record / document a crime and cannot be used for active prevention. There is no solution for actively intervening in a criminal offense using a mobile video mast that can be set up completely independently in any environment and, moreover, can be configured, managed and restarted completely remotely via cloud services.

Solution:

The solution to this problem can be found in the development of an island solution, which has appropriate design features and a combination of different technologies and cloud services:

Key data:

• - Steel construction divided into 10 segments with its own portable concrete foundation
• - 2 steel brackets with rotatable mounts (15 ° in both directions) for photovoltaic modules
• - Hydraulic hand pump
• - Variable height from approx. 4.5m - 6m
• - Can be rotated through 90 ° / 180 ° / 270 °
• - Base area 2.25mx 2.25m
  1. 1. Control cabinet with mobile industrial internet router and industrial PoE switch
• - Equipment of the security technology - maximum 2 x IP day / night cameras, 2 x IP thermal imaging cameras, 2 x IP / PoE spotlights, 1 x IP loudspeaker
• - Equipping the internet connection with a mobile internet router (network-independent)
• - Independent power supply with up to 120 watts of power through 2 x bifacial photovoltaic modules, MPPT charge controller, battery monitor, data logger and high-performance solar batteries for approx. 3 days of operation in complete darkness

Backend:

• - Cloud platform for live monitoring and remote maintenance, data analysis of photovoltaic technology (MPPT charge controller, battery monitor, batteries, data logger)
  • ◯ Adaptation of the charging algorithms
  • ◯ Protection of the battery against deep discharge
  • ◯ Possibility of remote restart of all active PV components
• - Cloud platform (video surveillance as a service) for live monitoring, remote maintenance and operation of the security (camera, headlights, loudspeakers)
  • ◯ User roles administration (users are only allowed to view one plant or plant groups)
  • ◯ Reliable detection using video analysis / thermal image
  • ◯ Automatic headlight activation when people intrude via IP camera trigger
  • ◯ Edge storage on SD card
  • ◯ Option to save on the Internet (on a German server with VdS certificate)
  • ◯ Possibility of remote restart of all monitoring technology used

Front end:

• - Video data can be called up via mobile device (Android / iOS) on site in the area of the mast
• - Push notification of the detected events to the end device
• - Security personnel have the option of using terminals
  • ◯ Use video image for verification
  • ◯ Activate headlights on the mast
  • ◯ Addressing perpetrators from a distance via loudspeaker

Achieved advantages:

The advantages of the invention include the minimization of acquisition and operating costs, since no earthworks or cabling work is required for the construction. The steel construction offers the possibility of erecting the monitoring mast independently of the local conditions on a leveled surface (without the necessary earth foundations). No crane technology is required for assembly and erection, as the mast segments are transported or assembled individually by 2 people and erected with a hydraulic hand pump. This also improves handling in impassable areas (e.g. between railroad tracks). The photovoltaic and storage technology used ensures self-sufficient operation for about 3 days in complete darkness. By using the two cloud services, the operator is able to monitor the status and operational readiness of the system at any time or to restore some of it. This ensures an improvement in monitoring and / or an increase in availability and further savings in maintenance and administration costs are achieved. Thanks to the use of innovative cloud technology, there is no need for central server and client technology at the site. The active prevention of criminal offenses or early detection offers an enormous advantage over conventional mobile masts. The optimization of the deterrent or "surveillance chain" is ensured through the use of thermal imaging technology and intelligent video algorithms. Instead of just recording the crime with conventional mobile masts, this can be actively prevented with the following surveillance chain. It is irrelevant whether the security guard is on site near the mast or acts from an alarm center.

Further embodiment of the invention:

The mast is modularly expandable. Depending on the requirements, the foundation can consist of your own mobile foundation (which has to be erected by two people) or a steel plate (e.g. for use at public events / in public places) or a steel root foundation (temporarily placed in the ground). The power supply can also be carried out variably directly via a power cable instead of the photovoltaic system. Networking is possible via the intended mobile Internet, but can also be established using radio relay or LAN (cable connection). Ultimately, the equipment of the monitoring technology can also be individually adapted. With approval from the Federal Railway Authority, the mast described can also be used at a short distance from railway tracks.

Description of an embodiment:

Use of a mobile and self-sufficient video surveillance mast in a parking track system to secure the parked vehicles from vandalism.

One problem in existing track storage systems is the impassable terrain due to countless parallel tracks. This prevents the erection of a stationary mast, as the costs for the foundation, development and erection are too high. The second big problem is the creation of a technical infrastructure (internet and power supply), since this also causes enormous and unacceptable costs. By using a mobile and self-sufficient video surveillance mast, it is possible to monitor the corridors between the track vehicles in a cost-saving manner. The mast segments can be brought to the installation site by 2 people via the tracks and erected and erected without crane technology. Two thermal imaging cameras use video analysis to detect opposite directions, the security staff on site receives a push message on a tablet / smartphone, and the IP lighting on the mast is automatically activated in parallel. The staff receives an alarm image via the push message from two additional cameras and is immediately able to verify the alarm. While the security personnel are getting closer to the potential perpetrator, they can address the perpetrator live via the IP loudspeaker via the mobile device and, if necessary, drive them away.

Claims (5)

The claim relates to the idea of developing / building a mobile and self-sufficient video surveillance mast with the inclusion or combination of various mechanical and electrical features, as well as various existing technologies (photovoltaics, cloud & push services, IP surveillance cameras including video analysis algorithms ) for cost optimization & maintenance optimization and to improve the thwarting of criminal offenses. 1. mechanical & structural features of mobile & self-sufficient cloud video surveillance mast; variable height; without concrete foundation; from several steel segments; Can be erected without crane technology in 2-man handling The mast is constructed from a total of 10 individual segments. The foundation consists of 4 steel frames (1125mm x 1125mm), which are screwed together to form a base plate (2250mm x 2250mm) (picture: mast base plate / mobile foundation). In addition, the foundation frames are each provided with a safety frame to secure the concrete slabs that are used for ballasting. In addition, the assembled base plate offers a mounting option for a control cabinet to accommodate all electrical and information technology systems. A total of 4 square tube parts are placed on the foundation. The first part has a length of 884mm and offers a cable outlet opening and the mounting of the tilting device of the mast. The second part has a length of 1436 mm and offers the receptacle for the hydraulic cylinder for erecting the mast. (Picture 3: mast tilted; picture 4: mast tilted and rotated by 90 °) The two brackets required for the PV modules are mounted on the third part, it has a length of 1500mm and is also provided with an inspection flap. The arms of the PV modules can also be rotated 15 ° in both directions. The top of the mast is manufactured with a length of 500mm - 2000mm, depending on the requirements, and is used to attach the IP surveillance components such as cameras, lighting or loudspeakers. The division of the mast into individual segments, as well as the tilting function and the erection of the 3 upper square tube parts via a hydraulic system enable the mast to be erected by two people without crane technology. The hydraulic system is only required for erecting or tilting the mast and can be dismantled while the mast is in use. 2. Electrical & IT features Autonomous power supply through photovoltaics (PV) including battery storage; IP-based cameras, lights and speakers; Management, configuration and monitoring of the IP and PV components based on cloud services; Remote control of the safety technology via mobile end devices The independent power supply is ensured via two bifacial PV modules and a storage system. The system consists of an MPPT charge controller, a battery monitor, a data logger and high-performance solar batteries. If consumers with a maximum of 120 watts are connected, operation in complete darkness for approx. 3 days can be guaranteed. The surveillance system consists of IP surveillance cameras (day / night or thermal image). The cameras have an open interface and can be equipped with various video analysis algorithms for the detection of people. The cameras, loudspeakers and lighting do not have an additional power supply, but are operated via Power-over-Ethernet. The power and data supply is ensured by means of a PoE switch. A mobile internet router is available for communication with the internet. The management, remote control and maintenance of the power supply and monitoring system is mapped using cloud services. The services enable a direct and secure VPN connection to the respective end device. The status of the battery system can be seen at any time and from any location. All installed devices such as charge controllers, battery monitors, data loggers and their values such as state of charge, DC voltage, solar yield, consumption, AC source can be evaluated and adjusted. The platform also issues an alarm in the event of failures and critical values. Similar to the battery system, the monitoring components are managed and monitored on an online platform. Here, too, the platform reports critical system states. In the event of an error, the corresponding system can be evaluated via remote access and the problem can be rectified; the technician only needs to be contacted in exceptional cases. Thus, the mast can be operated completely mobile, independently and cost-effectively without additional administration hardware and software. In addition, the cloud service of the monitoring system offers full control of the technology via a mobile web client (web and mobile device). The mast can be used by a security guard on site as an aid to deter criminal offenses. The security staff receives a notification via a push service and can remotely control the monitoring technology on the mast. The first sub-claim relates to the variability of the foundation. Depending on the claim and requirements, the mast can either be placed on a segmented steel frame including concrete slab ballast, as described in the main claim, or mounted on a steel plate or a steel root foundation (civil engineering work required). Instead of a mobile Internet router, a radio relay system to a nearby network can also be used to access the Internet. The combination of the installed IP monitoring components can be varied. The number of devices and the type of combination is not specified. Another version is the operation of the mast without a battery system. To do this, the boom, PV modules and batteries are removed and the mast can be supplied with power via a conventional 230V connection.
