technical field

The invention relates to a substation inspection offside alarm system, and also relates to a substation inspection offside alarm method, which belongs to the technical field of substations.

Background technique

At present, in the substation safety management, the internal equipment and inspection personnel have not been positioned and monitored. When the inspection personnel work, they only rely on their own safety awareness and work experience to judge the safe area. The inspection and supervision work is inconvenient to carry out, resulting in the low safety awareness of some inspection personnel, and there is no automatic alarm for non-registered personnel entering the dangerous area in the substation, which poses a large safety hazard.

With the development of wireless communication technology, there are no technical difficulties in the establishment of short-distance wireless communication networks in substations. On this basis, it is also possible to realize short-distance, high-precision positioning of personnel and equipment. However, due to the complexity of the internal equipment of the substation, many occlusions, dense distribution, and short safety distance of electrical equipment, a single positioning algorithm can no longer meet the accuracy requirements of the substation for short-distance positioning.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Figure 1, it is a structural block diagram of the substation inspection offside alarm system, which includes a remote management system, a registration module, a positioning module, a supervision module, an alarm module and a storage unit.

The remote management system is equipped with a wireless communication module, which is used to transmit equipment status information, positioning information, and interact with control information and voice information, and provide a wireless sensor access communication platform for substations for later wireless communication expansion.

The positioning module, the supervision module and the alarm module are respectively connected with the remote management system through wireless communication.

The positioning module is used for the inspection personnel and equipment positioning, and it is set on the safety tools of the inspection personnel together with the alarm module.

The alarm module includes a voice alarm module and a light alarm module, which can provide real-time early warning for illegal operations of the whole station, supplemented by sound and light alarm means, and reduce the occurrence of power safety production accidents.

The supervision module is installed on the substation site, including infrared detection sensors and video monitoring devices. For the offside detection function of non-registered personnel, infrared detection sensors and video monitoring devices are installed in the substation to monitor the location information of people who do not wear the positioning module in real time. When entering an important non-safety area, an alarm will be output. Both the infrared detection sensor and the video monitoring device communicate with the remote management system through the wireless communication module, and the wireless communication module opens a wireless air interface for sensing device access.

The storage unit is connected to the remote management system and is used to internally store the electronic map of the substation, registration information, equipment status information, etc.

The remote management system is also connected to a display system. When the inspectors register before work, the display system dynamically displays the job responsibilities, operating equipment and precautions of the corresponding inspectors.

The present invention also provides a substation inspection offside alarm method, which is implemented based on the above-mentioned alarm system, and specifically includes the following steps:

Step 1: According to the actual geographic information of the equipment in the substation, establish an electronic map of the substation, including: primary equipment, safety passages, cable trenches and supporting equipment, etc., clarify the relationship between equipment, equipment safety distance, safe working area and road information in the station, and displayed graphically.

Step 2: Confirm the on-site information and register the safety equipment for the patrol personnel, associate the serial number of the positioning module in the safety equipment with the equipment in the work content, and use it to confirm that the patrol personnel only work within the scope of their work , At the same time, the display system connected to the remote management system will dynamically display the inspection workflow, precautions and operating equipment to clarify the work content and reduce risks.

Step 3: Real-time positioning of all equipment and inspection personnel in the substation, combined with the real-time supervision module, to determine whether the inspection personnel are working within their registered work scope: if the inspection personnel are found to be in violation of regulations or non-registered personnel are offside, output Voice alert.

In order to improve the positioning accuracy, the real-time positioning in step 3 is realized by combining UWB precise distance measurement, position sensing, inertial navigation technology and erecting electronic fences. The management system combines the information of the expert database to provide real-time equipment status information query and operation guidance. The specific operation method of real-time positioning is as follows: for the open area of the substation, use UWB precise ranging technology to realize the positioning of inspection personnel and equipment with 10CM accuracy; preset coordinates for the primary equipment of the substation, and improve the geographic information modeling of the whole station; for equipment maintenance When working, the substation is in a complex environment covered by multiple metals, combined with position sensing, inertial navigation and erection of electric fences to realize the positioning of maintenance personnel and the division of boundary areas.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
