Surroundings monitoring apparatus, information processing terminal, information processing apparatus, and recording medium

1. A surroundings monitoring apparatus comprising:

a sensor configured to acquire detection information about a position of a predetermined monitoring target located in an area surrounding a work machine; and

a processor configured to

determine whether the monitoring target is in a predetermined range equal to or less than a predetermined distance from the work machine within a sensor range in which the sensor can acquire the detection information,

determine whether the monitoring target is in a first range in a height direction of the work machine with respect to a reference surface on which the work machine is positioned, and

output an alarm or restrict an operation of the work machine in response to determining that the monitoring target is in the predetermined range and the monitoring target is in the first range.

2. A surroundings monitoring apparatus comprising:

a sensor configured to acquire detection information about a position of a predetermined monitoring target located in an area surrounding a work machine; and

a processor configured to output an alarm or restrict an operation of the work machine in response to detecting that: the monitoring target is in a sensor range in which the sensor can acquire the detection information; the monitoring target is in a predetermined range equal to or less than a predetermined distance from the work machine; and the monitoring target is in a first range in a height direction of the work machine,

wherein the processor is configured to acquire information about cancellation of the alarm or the restricting of the operation at an outside of the work machine, and

wherein the processor is configured to, when the alarm is output or the operation is restricted, cancel the alarm or the restricting of the operation, in response to acquiring of the information about the cancellation.

3. The surroundings monitoring apparatus according to claim 2 , wherein the processor is configured to acquire a notification of permitting cancellation of the alarm or the restricting of the operation from an external device, and

wherein the processor is configured to cancel the alarm or the restricting of the operation, in response to acquiring of the notification of the permitting of the cancellation.

4. The surroundings monitoring apparatus according to claim 2 , further comprising:

an output device configured to notify an operator,

wherein the processor is configured to acquire information about confirmation of the surroundings of the work machine from an external device, and

the output device is configured to notify the operator of a content of the information about the confirmation of the surroundings of the work machine when the processor acquires the information about the confirmation of the surroundings of the work machine.

5. The surroundings monitoring apparatus according to claim 2 , further comprising an image-capturing device configured to capture an image of the surroundings of the work machine,

wherein the processor is configured to acquire, from the image-capturing device, the captured image including a predetermined person who is located in the area surrounding the work machine and who is in a predetermined pose or gives a predetermined gesture, and

the processor is configured to cancel the alarm or the restricting of the operation, in response to acquiring of the captured image including the person who is in the predetermined pose or gives the predetermined gesture, when the alarm is output or the operation is restricted.

6. The surroundings monitoring apparatus according to claim 2 , further comprising:

an input unit configured to receive information indicating an intention for cancelling the alarm or the restricting of the operation from the operator,

wherein the processor is configured to cancel the alarm or the restricting of the operation, on condition that the processor acquires the information and the input unit receives the information indicating the intention, when the alarm is output or the operation is restricted.
