Description

Technical Field

[0001] The utility model relates to the technical field of railway monitoring, in particular to a railway cable box monitoring device based on wireless transmission and self-power supply. Background Art

[0002] The railway electrical system uses signal equipment, communication equipment, and automation equipment to achieve functions such as safe operation of station trains, control and conversion of switches, communication, and dispatching.

[0003] Signal equipment is the most core, important and largest component. Among the equipment used outdoors, the cable box is the "link" and "blood vessel" of other equipment.

[0004] There are many types of outdoor cable boxes, most of which are made of SMC composite materials. The installation locations are scattered and the height from the ground also varies with the changes in terrain.

[0005] Considering the climate conditions in Hainan Province, there is abundant rainfall throughout the year, ranging from 1,000 mm to 2,600 mm, with an average annual rainfall of 1,639 mm. Typhoon rainfall accounts for a high proportion of this, and outdoor cable boxes are often "soaked in water" in this environment, which will cause the insulation of the cable to deteriorate, and in severe cases will cause "short circuit failures", affecting the normal operation of signal equipment. Utility Model Content

[0006] In order to solve the above existing problems, the utility model provides a convenient and practical railway outdoor cable box information monitoring device, that is, a railway cable box monitoring device based on wireless transmission and self-power supply. The utility model is implemented through the following technical solutions.

[0007] A railway cable box monitoring device based on wireless transmission and self-power supply, comprising an outdoor monitoring module and a handheld terminal;

[0008] The outdoor monitoring modules are provided in a plurality and are respectively placed in the cable box. The outdoor monitoring modules are provided with a monitoring host, a monitoring module antenna, a temperature and humidity sensor, a water immersion sensor and a built-in battery;

[0009] The handheld terminal is equipped with a wireless module and an antenna.

[0010] Furthermore, the outdoor monitoring module transmits sampling information via a wireless signal with a frequency of 470M.

[0011] Furthermore, the handheld terminal establishes a wireless connection with each of the outdoor monitoring modules via the wireless module.

[0012] The beneficial effects of the utility model are as follows: the monitoring device can conveniently, quickly and accurately locate the fault position, efficiently troubleshoot the fault, save manpower, material resources and time, achieve the goal of "condition-based maintenance" of electrical system equipment, is convenient and practical, and is worthy of popularization and application.

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0018] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0020] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] Example:

[0022] A railway cable box monitoring device based on wireless transmission and self-power supply, comprising an outdoor monitoring module 1 and a handheld terminal 2;

[0023] A plurality of outdoor monitoring modules 1 are provided, which are respectively placed in the cable box 3 (various cable distribution boxes of the electric service system are relatively dispersedly installed in the outdoor station field). The outdoor monitoring module 1 is provided with a monitoring host 101, a monitoring module antenna 102, a temperature and humidity sensor 103, a water immersion sensor 104 and a built-in battery 105. The outdoor monitoring module 1 is powered by the built-in battery, collects the temperature, humidity and water immersion information inside the cable box, and transmits the sampled information through a wireless signal with a frequency of 470M. In order to achieve a self-powered time of more than one year, the monitoring module is usually in an intermittent working state and is "woken up" by a handheld terminal (cooperating with a wireless module and an antenna);

[0024] The handheld terminal 2 is equipped with a wireless module 4 and an antenna 401, and has the following functions: equipment "wake-up", information collection, information classification (early warning and alarm information analysis), information storage, monitoring module configuration, station map configuration, alarm configuration, management personnel configuration, etc.

[0025] The utility model can conveniently, quickly and accurately locate the fault position, efficiently troubleshoot the fault, save manpower, material resources and time, and achieve the goal of "condition-based maintenance" of the electrical system equipment.

[0026] The appearance and size of the utility model can be adjusted according to the specific cable box, and the internal structure and principle remain unchanged.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
