The humiture wireless detecting system gathers by on-the-spot humiture instrument, be sent on the computer of master control computer room through transmission part, make operation or administrative staff can observe at any time the variation of on-the-spot humiture, in order to take in time corresponding treatment measures, guarantee the safety of industrial production, storage or greenhouse plants.Humiture is as one of controlled parameter main in the activities such as industry, storage, agricultural greenhouse plantation, and concerning production management, the humiture wireless detecting system is the basis of humiture analysis and control.Therefore the data that detect whether accurately, can stably be transferred to measurement and control host computer, be the effectively key point of operation of system.
In the present domestic computer humiture radio fest and control system, all be that wet, the temperature data that a plurality of wireless sensers detect is sent to accepting device by the ZIGBEE wireless technology and carries out data handling utility.In actual the use, sensor bulk is larger, and power consumption is relatively high, when particularly a plurality of transducers transmit signal simultaneously, easily loses data, and stable signal transmission is poor.This transmission can be summed up and be had following shortcoming: transmitting range is short, and such as the longer-distance transmission of need, the track laying cost is higher; Disturbed by all kinds of factors, and circuit easily suffers mechanical failure, installation strength is large.
In the prior art, especially in the process of sensor passes signal, because the difference in related field often is subject to different temperature, the impact of humidity, temperature and humidity not only can exert an influence to the signal ability, and long-term use also can produce erosion damage to antenna itself.In addition, because the difference of environment for use, in the past the sort ofly directly connect ensuing vertical row type antenna, more and more can not satisfy user's demand.
The utility model content
Problem to be solved in the utility model provides a kind of dedicated antenna that is used for the humiture detection system that can adapt to most of temperature, humidity and space structure.
The technical solution of the utility model is as follows: a kind of dedicated antenna for the humiture detection system, comprise wire and antenna part, and it is characterized in that described antenna part is the first helical antenna, the second helical antenna and triple helical antenna totally 3 sections antennas; The two ends of described the first helical antenna connect respectively the first wire and the second wire, the two ends of described the second helical antenna connect respectively the second wire and privates, the end that described privates is not connected with the second helical antenna is connected with the triple helical antenna, and the end that described the first wire is not connected with the first helical antenna is connected with the antenna working load; Described the first helical antenna, the second helical antenna and triple helical antenna are equipped with local shell outward; The pitch of described the first helical antenna is greater than the second helical antenna, and the pitch of described the second helical antenna is greater than the triple helical antenna; The length of described the first helical antenna is less than the second helical antenna, and the length of described the second helical antenna is less than the triple helical antenna.
Further, described a kind of monolithic case that has to replace local shell for the dedicated antenna peripheral hardware of humiture detection system.
Further again, described monolithic case or local shell are tin system.
Further, described the first helical antenna, the second helical antenna and triple helical antenna are the omnidirectional high-gain antenna.
Further, described the first wire, the second wire and privates are flagpole antenna.
Further again, but described the first wire, the second wire or privates are the shaft-like wire of bending.
Described a kind of dedicated antenna for the humiture detection system can adopt the associated mode structure to connect, and is special such as environment, also can adopt non-associated mode structural design or with the first wire, the second wire, one or more bending of privates.
The beneficial effects of the utility model are: by the increase to the outer local shell of antenna and monolithic case, effectively reduce high temperature, high humidity environment to the corrosiveness of antenna.By the structural design of non-in the past associated mode, so that antenna flexibility when mounted greatly improves, make its working range more wide.
