Problems solved by technology

At present, the ranging technology used by the operator in the substation mainly includes RFID technology, and the ranging accuracy is 3-5 meters. However, this ranging accuracy makes the accuracy of the positioning method not high, resulting in misjudgment of the actual position of the operator, which cannot meet the requirements. actual usage needs

Embodiment Construction

[0051] 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.

[0052] figure 1 It is a block diagram of a positioning system according to a specific embodiment of the present invention; figure 1 Tags are shown, which are carried by the operator, and four base stations are fixedly installed at the substation site. The tag communicates with the base station in real time, and the distance information in the base station processor is transmitted to the positioning server through TCP / IP, and the positioning server performs positioning calculation according to the received distance information, and calculates the position information of the operator.

[0053] The tag includes a power management module, an acceleration sensor and a tag processor, and a ranging m...

Abstract

The invention discloses a substation operation personnel positioning system and method. The system comprises a label, base stations and a positioning server. The label comprises a power management module, an acceleration sensor, a label processor and a distance measurement module based on an UWB (Ultra Wideband) technology. A power output end of the power management module is connected with powerinput ends of the acceleration sensor, the distance measurement module and the label processor. The distance measurement module realizes communication of the base stations and the label. According tothe system and the method, a DW1000 module is employed, and distance measurement precision of the DW1000 module reaches 15-30cm. Positioning is the positioning based on distance, so operation personnel locations can be positioned relatively accurately through improvement of the distance measurement precision, and system feasibility is improved. According to the system and the method, the acceleration sensor is added in the label, and when it is detected that an acceleration signal is smaller than a set threshold, the label enters a sleep state, so power consumption is reduced, and standby duration is extended.

Description

technical field [0001] The present invention relates to a personnel positioning system and method, more specifically, to a substation operator positioning system and method, and belongs to the technical field of positioning. Background technique [0002] There are many types of on-site operations in substations, mainly including switching operations, equipment maintenance, live cleaning, mechanical operations, and other construction operations. Many of them involve live operations. If the operations are not carried out according to the work tickets and operation tickets, it will directly lead to personal casualties. Personal casualties in substations not only cause harm to workers and families, but also affect the safe and stable operation of the power grid. The main reasons for the accident were illegal command and operation; inadequate safety management and weak safety awareness of the operators. If the operator can be positioned and reminded of entering the dangerous are...
