Abstract
The utility model relates to a wireless temperature monitoring node, comprising a flat antenna and a wireless temperature sensor. The wireless temperature sensor comprises a sealed sensor housing made of metal, a circuit board and a battery, wherein a metal thermal conductive pedestal is arranged in the bottom of the sensor housing. The wireless temperature monitoring node is characterized in that the flat antenna comprises a cover-shaped antenna housing made of metal and an antenna made of sheet metal, wherein the antenna does not contact with the antenna housing, the antenna housing is connected with the top of the sensor housing, and a feed line penetrating through the sensor housing and connected with the antenna is arranged on the circuit board. The wireless temperature monitoring node of the utility model can satisfy application requirements of high-voltage and ultrahigh-voltage power transmission and transformation equipment, and is characterized by small volume, low cost, high efficiency and the like.
Description
Technical field
The invention belongs to electronic information field, is a kind of based on the WSN(wireless sensor network) technology, use the wireless temperature monitoring node of special-shaped miniature plate antenna.
Background technology
In Operation of Electric Systems, the position loose contacts such as busbar tie point, chopper switch, cable splice, agingly will cause overheatedly, excess current also will cause relevant device overheated.Apparatus overheat will cause again insulation damages and produce insulation ag(e)ing even causing short trouble.Therefore, the temperature monitoring of high-tension apparatus is the important means that guarantees the high-tension apparatus safe and reliable operation.
Due to specific questions such as the high voltage of high-voltage system, high-intensity magnetic fields, guarantee temperature monitoring system safe and reliable of high-tension apparatus, with regard to problems such as the reliable isolation that must solve high-voltage side information acquisition and low voltage side, communications, therefore, currently mainly take as the leading factor with wireless communication technique.But due to the singularity of high voltage installation, the Antenna Design of radio communication is the key issue that must solve, and two kinds of antennas are arranged usually: a kind of is cylindrical antenna, and a kind of is tours antenna.The electric charge that is near the most advanced and sophisticated side of the cylindrical antenna of high-voltage system is intensive especially, and near it, airborne electric field is strong especially, very easily produces point discharge phenomenon.Therefore, be not suitable for selecting cylindrical antenna in high-voltage system, equally also be not suitable for using tours antenna.
Summary of the invention
The purpose of this utility model is to propose a kind of wireless temperature monitoring node that is applicable to high-voltage system.
the purpose of this utility model is to realize like this, wireless temperature monitoring node of the present utility model comprises plate aerial and radio temperature sensor, wherein radio temperature sensor comprises the metal sensor housing of sealing, circuit board and battery, metal heat conducting base is arranged at the bottom at sensor housing, it is characterized in that plate aerial comprises the metal antenna casing that covers shape and the antenna that sheet metal is made, antenna does not contact with antenna casing, above-mentioned antenna casing is connected to the top of sensor housing, there is feeder line penetration sensor housing to be connected with antenna on the foregoing circuit plate.
Wireless temperature monitoring node of the present utility model greatly reduces caused point discharge phenomenon when using on high voltage installation, satisfy the application demand on high pressure and ehv power transmission equipment.Have that volume is little, cost is low, the efficient high.
Description of drawings
Fig. 1 is the structural representation of wireless temperature monitoring node of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
as shown in Figure 1, wireless temperature monitoring node of the present utility model comprises plate aerial and radio temperature sensor, wherein radio temperature sensor comprises the metal sensor housing 22 of sealing, circuit board 24 and battery 23, in the bottom of sensor housing 22, metal heat conducting base 25 is arranged, it is characterized in that plate aerial comprises the metal antenna casing 11 that covers shape and the antenna 12 that sheet metal is made, antenna 12 does not contact with antenna casing 11, above-mentioned antenna casing 11 is connected to the top of sensor housing 22, there are feeder line 21 penetration sensor housings 22 to be connected with antenna 12 on foregoing circuit plate 24.
