A security device characterized by having the following features.
6. A work robot that is autonomously mobile and performs predetermined tasks other than security within the monitored area, is connected to a security device that has setting means for switching between multiple security modes, including a security set mode which is set when the monitored area is unoccupied and monitors the monitored area using security sensors, and a security deactivation mode which is set when the monitored area is occupied and does not monitor the monitored area using security sensors, and performs predetermined tasks other than security within the monitored area . A control means that controls the system to start the predetermined operation assuming that there are no users within the monitored area when the security mode is the security set mode, A work robot characterized by having the following features.

Description

This invention relates to a security system, server, security device, and work robot. Conventionally, systems have been developed to cause work robots to perform predetermined actions based on their operating schedules. For example, Patent Document 1 discloses a method for generating operating schedule information for a robotic vacuum cleaner that cleans a room based on schedule information indicating the actions of multiple users, and controlling the operating operation of the robotic vacuum cleaner based on the generated operating schedule information. Japanese Patent Publication No. 2019-217164 This figure shows a schematic configuration of a security system according to one embodiment of the present invention.This is an example of a work area table 120.This is a floor plan of an office, which is an example of a work area.This is a plan view of the first work area 111.This flowchart shows an example of the start determination process performed by server 10.This flowchart shows an example of the work area extraction process performed by server 10.This flowchart shows an example of termination determination processing by server 10.This diagram shows the configuration of another security system 2.This is a diagram showing the configuration of another security system 3. The following describes a security system according to one embodiment of the present invention with reference to the figures. However, it should be understood that the present invention is not limited to the embodiments shown in the drawings or described below. Figure 1 is a diagram illustrating the schematic configuration of a security system according to one embodiment of the present invention. As shown in Figure 1, the security system 1 comprises a server 10, a security device 20, and a work robot 30. The server 10 is installed in a security center or the like and is connected to the security device 20 and the work robot 30 in a communication manner to manage the entire security system 1. The security device 20 is connected to the server 10 in a communication manner and provides security for, for example, an office, store, or factory. Here, the security target is composed of one or more security sections. The work robot 30 is connected to the server 10 in a communication manner via an access point 40 and performs work within the security target where the security device 20 is installed. The security device 20 is also connected to various devices and sensors such as a security operation unit 251, an intrusion sensor 252, and a fire sensor 253 via wired/wireless communication. In Figure 1, only one security device 20 and one work robot 30 are shown, but the security system 1 may have multiple security devices 20 and/or work robots 30. Server 10 is a cloud server or similar on a wide-area communication network such as the Internet. Server 10 includes a communication unit 11, a storage unit 12, and a control unit 13. The communication unit 11 has a communication interface circuit conforming to wired/wireless communication standards such as Ethernet® and IEEE 802.11, and communicates with the security device 20 and the work robot 30 via a wide-area communication network such as a LAN and the Internet to send and receive various signals. The storage unit 12 includes semiconductor memory such as ROM, RAM, and EPROM, magnetic storage media such as magnetic disks (HDD), and/or optical storage media such as DVD-RAM. The storage unit 12 stores the code and various data of the computer program executed by the control unit 13 to control the operation of the server 10. The computer program can be installed in the storage unit 12 by known methods via a computer-readable storage medium such as a DVD-ROM or a communication line. The storage unit 12 stores the work area table 120. The storage unit 12 is an example of a storage means. Figure 2 shows an example of a work area table 120. The work area table 120 stores information such as work time information, security maps, and the latest status of each work area, with these information being linked to each other. The work area indicates the region where the work robot 30 will perform its tasks. The work time information includes the available work time, the time when security deactivation is prohibited, the expected arrival time, and the duration of the work. The available work time indicates the time period during which the work robot 30 is permitted to perform work. The time when security deactivation is prohibited indicates the time period during which the transition from security set mode to security deactivation mode is prohibited in the work area that is subject to security, such as during late-night hours when no user entry is expected. Details of security set mode and security deactivation mode will be described later. The expected arrival time indicates the time when the first employee is expected to arrive at the work area. The duration of the work indicates the time required for the work to be per
