The integrated structure of the capacitive-gate displacement sensor and the wireless communication component in the utility model replaces the soft temporary connection between the sensor and communication transponder in the separated system, which is convenient for measuring and installing and effectively reduces the fault caused by bad plug contact or break when in soft temporary connection and is also good for water repellent.
Description
Technical field
The utility model relates to a kind of capacitive displacement transducer, specifically is meant the integrated capacitive displacement transducer that carries the wireless communication interface unit.
Background technology
Capacitive displacement transducer is a digital sensor, its core is the capacitive grid numeral display unit, because the level of data output is faint, form is special, therefore can not teletransmission, so this signal must be through special amplification, relaying, the equipment of finishing this task is commonly referred to " interface unit ", specifically is divided into " wired interface unit " and " radio interface unit " two kinds, and these two kinds are independent product sold.Existing " radio interface unit " normally carries out data transmission by soft electric wire and capacitive displacement transducer, and " radio interface unit " arrives Measurement and Data Processing equipment to data transmission by wireless mode more then.Because " radio interface unit " separates setting with sensor, need install and fix respectively during use, very inconvenience, and adopt electric wire to be connected between " radio interface unit " and the sensor by connector, often plug is easy to produce the fault of loose contact or broken string.
The utility model content
The problem that the utility model need solve provides the setting of a kind of capacitive displacement transducer and wireless communication interface unit integral, New Displacement Transducer easy for installation.
According to the above-mentioned problem that needs solution, the utility model has designed a kind of integrated capacitive displacement transducer, it comprises sensor body that is used for displacement measurement and the wireless communication assembly that is used for data transmission, described wireless communication assembly disposes a housing, wireless communication assembly is installed in the housing, by housing and sensor body stiff assembly together.
Concrete, described sensor body and housing for can be for convenience detach be rigidly connected, for example connect or the connection of dovetail groove buckle with screw Luo.
Described integrated capacitive displacement transducer sends the measurement main frame to by the data of wireless transmission method after with acquisition process.
Compared with prior art, advantage of the present utility model is: the integrated wireless design of (1) sensor and wireless communication assembly, and make water-proofing treatment become simple, only need whole plastic covering film just can reach the effect of integral waterproofing fast; (2) easy to install; after having adopted integrated design; only need one-time fix; whole displacement information measurement point is just fixing; the separate type measuring system is except the needs fixation of sensor; also need to consider how to lay wireless telecommunications transponder (interface unit); and the general cable etc. of adopting carries out soft interim connection between the two; the fault of connector loose contact or broken string appears in this connection through regular meeting; adopt the on-the-spot checkout equipment of this programme; even if through repeatedly dismounting, the reliability of displacement detection system still can not descend.

Fig. 3 forms schematic block diagram for the utility model internal circuit.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the utility model comprises sensor body 1 that is used for displacement measurement and the wireless communication assembly 2 that is used for data transmission, described wireless communication assembly 2 configurations one housing 3, wireless communication assembly 2 is installed in the housing 3, by housing 3 and sensor body 1 stiff assembly together.
Described sensor body 1 and housing 3 for can be for convenience detach be rigidly connected, for example connect or connect with the dovetail groove buckle with screw Luo.
As Fig. 1,2,3, sensor body 1 described in the utility model specifically comprises housing 11, measuring staff 12 and capacitive grid numeral display unit 14, and described measuring staff is connected with placing housing grizzly bar 13 decided at the higher level but not officially announced.
Measuring staff contacts extraneous mobile object, be subjected to the mobile object promotion and then make the fixed grid bar with respect to the capacitive grid numeral display unit motion, the move distance of fixed grid bar is read in the capacitive grid numeral display unit, draws numerical value, in with the digital form display result, constantly send the result to wireless communication assembly.
Described wireless communication assembly 2 adopts wireless mode and measures the main frame wireless telecommunications.Wireless communication assembly 2 specifically comprises governor circuit 21 and the data acquisition circuit 22, zeroing circuit 23, code selection switch 24, the wireless transceiver circuit 25 that are connected with governor circuit.Wireless transceiver circuit 25 is furnished with antenna 25-1, and this antenna stretches out in housing 3.
The utility model adopts powered battery.
In the practical application, a measurement main frame can be with a plurality of described integrated displacement transducer work simultaneously, form a wireless displacement measurement system, each sensor all has this machine geocoding on the measurement main frame in system, and this coding is to be determined by each on off state combination of code selection switch 24.
Principle of work of the present utility model is: the function class that the folding of the code selection switch arrays of described wireless communication assembly 2 itself is combined to form is like people's ID (identity number) card No., the governor circuit 21 of band microprocessor is constantly intercepted from the wireless calling of measuring main frame in the wireless communication assembly 2, when the wireless calling information that receives and this machine geocoding meet, the displacement data that governor circuit 21 control data Acquisition Circuit 22 read sensor bodies 1 are measured is then together with sending to the measurement main frame by wireless transceiver circuit 25 after the information package such as this machine geocoding, data check.
Measure the call information that main frame can also send special instruction, governor circuit can according to the instruction of measuring main frame to the capacitive grid numeral display unit return to zero, controlled operation such as maintenance.
When system did not receive the wireless calling of measuring main frame for a long time, governor circuit can send instruction, and the control wireless transceiver circuit changes frequency, to reach the purpose of select frequency automatically.
In the described wireless communication assembly 2 status indicator lamp that is connected with governor circuit 26 can also be set, pilot lamp is distinguished the normal condition of display power supply and communication by modes such as " growing bright ", " flickers ".
After the utility model is finished using, can be disassembled into " wireless communication assembly of charged pool " and " capacitive displacement transducer " two parts, be easy to carry.
