[0001] IP camera system with a zigbee signal receiving device [0002]

The present invention relates to an IP camera system equipped with a ZigBee receiving apparatus, and more particularly to a ZigBee signal generating apparatus equipped with a ZigBee sensing unit in an IP camera to constitute a sensing node of the object Internet in a monitoring target area, By receiving the ZigBee signal and transmitting it to the central monitoring center or the ZigBee server, it is possible to confirm whether the wearer of the ZigBee signal generating device is the sender of the report by using the object Internet, The present invention relates to an IP camera system equipped with a Zigbee sensing unit.

The Internets of Things (IoT) defined by the International Telecommunication Union (ITU) is a concept in which advanced services are exchanged by exchanging information at anytime and anywhere via the network.

A typical object Internet architecture is divided into sensing, network, and application system domains. In particular, the sensing domain is an environment in which physical objects exist, such as a Wi-Fi (Wireless Local Area Network) and a Personal Area Network (WPAN) such as Bluetooth, ZigBee and UWB .

The Internet, which is composed of various networks, should be supported by technologies that support identification, sensing, and communication of objects. WSN (Wireless Sensor Network) is a useful technology.

The WSN is an ad hoc network composed of a wide range of wireless sensor nodes in a physical space. Each wireless sensor node is composed of an MCU, a sensor, a wireless communication module, and a power supply. And provides a service for remotely controlling the device through the wireless communication module.

The information and services in the WSN are delivered to the sink node and delivered through the network domain to be used in various applications such as local monitoring and power supply control. Beyond simple information exchange between sensing domain and application system, more intelligent and advanced services are possible if information exchange is made between sensing domains composed of various networks.

Along with the frequent occurrence of vehicle theft and loss of goods, there are increasing accidents in which elderly people with dementia, mental retarded children and their caregivers who are rapidly increasing due to population aging are getting lost, and accidents of this kind are inconvenient.

However, it is not easy to find objects such as stolen and lost vehicles, lost items, elderly people who have lost their way, mental retarded children, infants and the like. Especially in the case of vehicles or people with mobility such as people, it is more difficult to find them. Long-term effort by a large number of people was required.

However, the above-described problem can be solved to some extent through the application of a GPS or the like as a satellite-based position tracking system. That is, a transmitter can be installed on the object to communicate with the satellite directly or indirectly, thereby locating the object.

However, the above-mentioned system has a disadvantage that expensive equipment and a charge are required, and thus it can not be widely used as general equipment. In addition, when the object is located in a place where the object can not be traced such as in a building or underground, the GPS can not sufficiently confirm the function of the object in the downtown area where buildings and underground facilities are concentrated, .

In addition, in the case of the location service using the mobile communication network, it is possible to grasp the approximate position of the object having the mobile terminal, but it is difficult to grasp the situation at the place where the object is located.

Since the information is insufficient to determine the situation at the location where the object is located, the judgment for the action is inaccurate and the appropriate action is delayed when the specific event occurs. Also, after the position of the object is detected, it is not possible to know the exact situation until it arrives at the site, so it is difficult to take immediate action for the protection of the person or the safety of life

In Korean Patent No. 10-0725262, in order to confirm the location of a lost vehicle, an article, or a lost child, it is possible to reduce the cost burden due to the input of expensive equipment or a lot of manpower, to provide accurate location information of the object, There has been proposed a technique for providing a monitoring and control system such as a streetlight, a security, and a location confirmation method capable of checking the location of an object capable of real-time tracking without discrimination in the underground or underground.

Korean Patent No. 10-1142933 discloses a location-based service that enables users to know the location and situation of a subscriber accurately and quickly when a dangerous situation or an emergency occurs, and to take prompt action to keep the subscriber's safety on the basis thereof A CCTV camera device using a service, a security control center server, and an intelligent security system including the security server have been proposed.

Korean Patent No. 10-0779901 discloses a mobile terminal equipped with a Zigbee communication function that enables a free data service in a short range communication or a local range by installing a Zigbee communication function in a portable terminal and a data service method using the terminal .

FIG. 1 is a block diagram showing a configuration of a terminal capable of Zigbee communication according to a conventional technique.

 A portable terminal capable of Zigbee communication according to the related art includes a transceiver 1, a processor 2, a mobile communication antenna 8, an RF unit 6, a storage unit 5, an audio processing unit 7, a keypad 4, and a display unit 3.

Here, when the light emitting distance of 500 m or more is enabled, the consumed electric power is increased, and the internal temperature of the IP camera 100 mounted on the Zigbee is increased. As a result, the operation of the camera is unstable and the service life is shortened.

In order to prevent such internal temperature rise, the camera 10 senses an image only at a zoom magnification that is currently being operated as shown in Table 1. Therefore, the zoom magnification adjustment signal transmitted from the central monitoring center or the Zigbee server 210 is supplied to the microcomputer 30, Is stored in the built-in memory of the microcomputer 30 in advance as shown in Table 1, and the microcomputer 30 calculates current data corresponding to the zoom magnification of the stored data And controls the infrared ray projector 15 so as to match the zoom magnification so that the power consumption can be stably operated at a half or less even during the middle distance operation to prevent thermal runaway.

Room distance LED Floodlight Laser emitter electric current Brightness (hexadecimal) electric current Brightness (hexadecimal) 40m 0.1A 7A 60m 0.2A A4 80m 0.3A B3 100m 0.4A D1 140m 0.5A E0 200m 0.6A FE 250m 0.1A 7A 300m 0.2A A4 350m 0.3A B3 400m 0.4A D1 450m 0.5A E0 500m 0.6A FE

For example, when the zoom magnification of the camera 10 is set to 1x to monitor a wide field of view, the laser 10 is operated in the 40m mode of the emission range of " Table 1 ", so that the laser diode emitter (15b) stops the operation so that heat is not generated on the side of the laser diode floodlight (15b) to prevent thermal diffusion.

Conversely, in order to monitor the longest distance, the central monitoring center or the Zigbee server 210 operates the zoom magnification at the greatest magnification, and when the emission distance is 500 m, the microcomputer 30 detects the zoom magnification adjustment signal, The infrared LED floodlight 15a having a projection distance of 200 m or less is turned on by applying 0.6 A to the laser diode floodlight 15b used for medium distance light projection from 200 m to 500 m, So as to minimize heat generation, thereby preventing operation anxiety due to heat generation.

In this way, the infrared LED floodlight 15a and the laser diode floodlight 15b are selectively operated according to the zoom distance by the microcomputer 30, thereby reducing the heat dissipation and thus making it possible to observe the image at nighttime over 500 m.
