Abstract

A security system comprises a first sensor disposed in an area to be monitored in a building to monitor the area; a moving robot having a robot main body, a second sensor for monitoring the area to be monitored and a robot operation processor for moving the robot main body according to an operation mode data indicating an operation of the robot main body; a controller including first and second sensor information monitor means for collecting first sensor information and second sensor information which are acquired by the first and second sensors, and an operation mode data generator for generating the operation mode data from the first sensor information or the second sensor information and transmitting the operation mode data to the robot operation processor.

Claims

1. A security system comprising:

a first sensor disposed in an area to be monitored in a building, to monitor the area;

a moving robot having a robot main body, a second sensor for monitoring the area to be monitored and a robot operation processor for moving the robot main body according to an operation mode data indicating an operation of the robot main body; and

a controller including first and second sensor information monitor means for collecting first sensor information and second sensor information which are acquired by the first and second sensors, and an operation mode data generator for generating the operation mode data from the first sensor information or the second sensor information and transmitting the operation mode data to the robot operation processor,

wherein

the controller further includes a remark level data memory storing remark level data indicating a monitoring weight for a target to be monitored by the first sensor or the second sensor,

the remark level data processor renews the remark level data in the remark level data memory by using the first or the second sensor information during a patrol operation of the robot, and

the moving robot patrols in the building on the basis on the remark level data and the operation mode data.

2. A moving robot provided in a security system, which includes a stationary sensor installed in an area to be monitored in a building, to monitor the area and a server transmitting abnormal condition data indicating an abnormal condition when the stationary sensor detects the abnormal condition, comprising:

a robot main body movable in the area to be monitored;

an on-board sensor mounted on the robot main body to monitor the area;

a sensor information monitor which, during use, collects at least on-board sensor information acquired by the on-board sensor;

an operation mode data generator which, during use, generates operation mode data of the robot main body by using at least the on-board sensor information;

a robot operation processor which, during use, activates the robot main body in accordance with the operation mode data;

a remark level data memory which, during use, contains remark level data which indicates a monitoring weight for a target to be monitored by the stationary sensor or the on-board sensor; and

a remark level data processor which, during use, renews the remark level data in the remark level data memory by using the on-robot sensor information during a patrol operation of the robot,

wherein

the moving robot cooperates with the stationary sensor to monitor the area to be monitored and

the moving robot patrols in the building on the basis of the remark level data and the operation mode data.
