The method can be executed by a regional anti-misentering device which can be realized in a form of hardware and/or software, the regional anti-misentering device can be configured in regional anti-misentering equipment, and the regional anti-misentering equipment is applied to a regional anti-service system. As shown in fig. 1, the method includes:

s110, acquiring distance data in a preset area corresponding to the target equipment acquired by the distance sensor, wherein the distance data comprise the distance between the moving object and the target equipment.

In the present embodiment, the distance sensor may be understood as a device for measuring a distance between objects, and may include an ultrasonic distance measuring sensor, a laser distance measuring sensor, an infrared distance measuring sensor, and the like, for example. The target devices include devices that are used in substation bays, such as circuit breakers, disconnectors, operating mechanisms, terminal boxes, net doors or screen cabinets, etc. The substation interval is provided with a plurality of target devices. The preset area includes an area within a certain distance range centered on the location of the single target device. Moving objects include objects that can be dynamically moved, such as humans or animals. The distance data includes a distance between the moving object and the target device, such as a distance between a worker to the target device.

Meanwhile, a corresponding distance sensor is configured for each target device so as to acquire distance data between a moving object and the target device in a preset area corresponding to the target device in real time, deployment positions of the distance sensors corresponding to different target devices can be different, for example, the distance sensors associated with a net door or an operating mechanism are deployed on a door handle, the distance sensors associated with a grounding pile are deployed on a lock cylinder so as to facilitate the acquisition of the distance data, and further the distance data acquired by the distance device are acquired.

Specifically, according to the acquired distance data, whether the distance between the moving object and the target device is smaller than a preset distance threshold value is judged. If yes, executing S130; otherwise, S110 may be performed back to enable real-time supervision of the distance between the moving object and the target device. Illustratively, when the preset distance threshold is 30cm and the distance between the worker and the target device is 29cm, which is less than the preset distance threshold, S130 is performed.

In the context of the present invention, a computer-readable storage medium may be a tangible medium that can contain, or store a computer program for use by or in connection with an instruction execution system, apparatus, or device. The computer readable storage medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. Alternatively, the computer readable storage medium may be a machine readable signal medium. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.

The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.

It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps described in the present invention may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present invention are achieved, and the present invention is not limited herein.

The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
