Description
Technical field
The utility model relates to a kind of two redundancy intelligent pressure sensor.
Background technology
In the every system of current aerospace space industry, in order to the running status of surveillance, improve runnability and the reliability of system, need to carry out real-time online measuring to the parameters of system, wherein, pressure is exactly an a kind of very general and important parameter.
Current traditional pressure measurement method is by distributed measurement, each electric pressure signal is collected central control system and focuses on.Like this, measure pressure transducer many, wiring is complicated, and reliability is not high, does not meet the light weight of aerospace field, miniaturization, high reliability request.Further, along with system stream time is more and more longer, also more and more higher to the continuous working life requirements of various unit product, therefore, redundancy protecting design is carried out to important unit product requirement.The redundancy protecting part when unit damage of product can be avoided like this to work on, and guarantee system is normally run.
For this reason, in the urgent need to studying a kind of new pressure transducer, can simultaneously on-line measurement multiplexer channel pressure, to meet the measurement requirement of intelligent pressure sensor array of light weight, miniaturization, band redundancy protecting.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, provides a kind of two redundancy intelligent pressure sensor, solves current multichannel pressure channel measurement volumes large, poor reliability, the problem of irredundant design protection.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of two redundancy intelligent pressure sensor, and comprise base plate and enclosing cover, described enclosing cover is fixed on base plate, and forms confined space with described base plate; Base plate both sides in described confined space are all fixed with pillar; Base plate between the pillar of both sides is fixed with more than one for connecting the array element module of measurand; Described pillar is fixed with data acquisition board; Described outer covering is fixed with electric connector.
Described array element module comprises hollow base, and described pedestal top is fixed with gland; Pedestal internal fixtion below described gland has pressure sensitive core, is provided with O-ring seal between described pressure sensitive core and described pedestal; Described pedestal outside surface is fixed with digital conditioning plate.
Described digital conditioning plate is fixed on described pedestal by insulating mat.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is by array element module Miniaturization Design, concentrate in small space and measure multichannel pressure channel, decrease quantity and the volume of pressure transducer, reduce the weight of sensor, decrease the complicacy of sensor wiring, improve the reliability of sensor; Array element modular design, enhances the dirigibility of intelligent pressure sensor array, facilitates selection and the maintenance of array element range; Each array element module has presser sensor chip, is equivalent to each array element and adds redundancy protecting, improve the reliability of array element.The utility model structure is simple, is easy to manufacture, and can make improvements to adapt to different demand according to different application occasion.

Embodiment
As depicted in figs. 1 and 2, the utility model one embodiment comprises base plate 1 and enclosing cover 6, and described enclosing cover 6 is fixed on base plate 1, and forms confined space with described base plate 1; Base plate 1 both sides in described confined space are all fixed with pillar 3; Base plate 1 between the pillar 3 of both sides is fixed with more than one for connecting the array element module 2 of measurand; Described pillar 3 is fixed with data acquisition board 5; Described enclosing cover 6 is fixed with electric connector 4.
As shown in Figure 3, described array element module 2 comprises hollow base 21, and described pedestal 21 top is fixed with gland 26; Pedestal 21 internal fixtion below described gland 26 has pressure sensitive core 22, is provided with O-ring seal 25 between described pressure sensitive core 22 and described pedestal 21; Described pedestal 21 outside surface is fixed with digital conditioning plate 23 by insulating mat 24.
Array element module converts pressure signal to electric signal, and be sent in data acquisition board by electric signal after digital conditioning plate conditioning, data are sent on data bus by electric connector by data acquisition board by pressure on the number signal after treatment again.
Array element module of the present utility model can select suitable pressure range needed for actual, and pressure range ability is optional from 0 ~ 100kPa to 0 ~ 10MPa.The impulse mouth of array element module can be matched according to actual interface, such as hickey or fast connection interface etc.The pressure signal of array element module uses digital conditioning plate to compensate in full warm area operating temperature range it, and converts thereof into digital quantity and be sent to data bus collection plate.The pressure sensitive core of array element module is two-way pressure sensitive core (two-way pressure sensitive core describes in detail in patent CN 203365047 U); this core body comprises the identical presser sensor chip of two ranges; two presser sensor chips are in same base; experience identical pressure, play a part redundancy protecting.
