Monitoring device and monitoring method
First Claim
1. A monitoring device comprising:
- a memory which stores first and second background information related to positional information of a fixed object existing in a detection area of a radar device that receives a reflected wave from an object existing at an emission destination of an emitted radar wave and detects position and moving velocity information of the object as detection information of the object;
an interface device which manages data transfer with the radar device and higher level device that are connected to the monitoring device, wherein the higher level device instructs the monitoring device to change an operation mode of a monitoring process, and acquires and manages results of monitoring output from the monitoring device; and
a processor which performs processes including;
a first detecting process which detects, upon receiving a first specified signal sent from the higher level device to the processor through the interface device, a temporary fixed object that includes an obstruction existing in a detection area of the radar device by using the detection information and the first background information stored in the memory, and which outputs detection result to the higher level device through the interface device; and
a second detecting process which detects, upon receiving a second specified signal sent from the higher level device to the processor through the interface device, a movement object existing in the detection area of the radar device by using the detection information and the second background information stored in the memory, and which outputs detection result to the higher level device through the interface device.

Abstract
A monitoring device includes a memory configured to store first and second background information related to positional information of a fixed object existing in a detection area of a radar device that receives a reflected wave from an object existing at an emission destination of an emitted radar wave and detects position and moving velocity information of the object as detection information of the object; and a processor configured to detect, upon receiving a first specified signal, a temporary fixed object existing in a detection area of the radar device by using the detection information and the first background information stored in the memory, and to detect, upon receiving a second specified signal, a movement object existing in the detection area of the radar device by using the detection information and the second background information stored in the memory.

6. A monitoring method comprising:
-
acquiring, by using a processor, detection information output from a radar device connected to the processor through an interface device, wherein the radar device receives a reflected wave from an object existing at an emission destination of an emitted radar wave and detects position and moving velocity information of the object as detection information of the object; detecting, by using the processor, upon receiving a first specified signal sent from a higher level device to the processor through the interface device, a temporary fixed object that includes an obstruction existing in a detection area of the radar device by using the detection information detected by the radar device and first background information, the first background information being positional information of a fixed object existing in a detection area of the radar device; detecting, by using the processor, upon receiving a second specified signal sent from the higher level device to the processor through the interface device, a movement object existing in the detection area of the radar device by using the detection information detected by the radar device and second background information, the second background information being positional information of a fixed object existing in a detection area of the radar device and being different from the first background information; and outputting, by using the processor, a detection result to the higher level device through the interface device.

7. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process comprising:
-
acquiring detection information output from a radar device connected to an interface device of the computer, wherein the radar device receives a reflected wave from an object existing at an emission destination of an emitted radar wave and detects position and moving velocity information of the object as detection information of the object; detecting, upon receiving a first specified signal sent from a higher level device to the computer through the interface device, a temporary fixed object that includes an obstruction existing in a detection area of the radar device by using the detection information detected by the radar device and first background information stored in a storage unit, the first background information being positional information of a fixed object existing in a detection area of the radar device; detecting, upon receiving a second specified signal sent from the higher level device to the computer through the interface device, a movement object existing in the detection area of the radar device by using the detection information detected by the radar device and second background information stored in the storage unit, the second background information being positional information of a fixed object existing in a detection area of the radar device and being different from the first background information; and outputting a detection result to the higher level device through the interface device.
