Background technology
Sea cock and valve is one of the key role that can emit on the truck tanker jar interior oil plant.Only if the destruction vehicle structure, backing down sea cock and valve with pressure gas is the main method of emitting jar interior oil plant.General use lead sealing protection oil outlet, but actual anti-theft effect is very unreliable.Sensor in this position reliable installation carries out on-line monitoring to the sea cock and valve cylinder, can obtain opening/closed operation information of cylinder at any time.Through continuous record sea cock and valve operation information data, and suspicious operation in time reported to the police, thereby prevent that effectively the oil plant under improper situation from emitting behavior, with the safety and the antitheft of protection petroleum transported and storage.
For antitheft of often being attacked and safety apparatus; Its sensor fixing structure must be firmly; And possess self-protection ability, system must adopt the intelligent digital communication that possesses data encryption and self diagnostic capability to be connected, and will accomplish that installation and maintenance is simple.
Based on as above requirement, if still adopt conventional being electrically connected and structure,, be easy to be cracked like on-off signal etc., self is also unreliable, and this just needs to propose new Sensor Design and structure design, adopts a kind of failure-free system connection mode.
The utility model content
The purpose of the utility model is: to the problem of above-mentioned prior art existence; A kind of truck tanker sea cock and valve antitheft digital pressure sensor device based on the CAN bus is proposed; Sea cock and valve cylinder on the truck tanker carries out real time monitoring, is not arbitrarily emitted with the stored oil plant with transportation of protection truck tanker.
In order to solve above technical matters, the utility model provides the truck tanker sea cock and valve antitheft digital pressure sensor device based on the CAN bus, comprises that being fixed on sea cock and valve forms the protective case seat of enclosing on every side and be connected the over cap on the said protective case seat; One side of said protective case seat links to each other with said over cap through place's hinge at least, after protective case closes, is connected by lock bolt all around; It is characterized in that: on the sea cock and valve valve body in said protective case seat pressure sensor is installed, the test side of said pressure sensor is connected with oil tank inside, and the signal output part of pressure sensor is connected with the communication of exterior monitoring device through the CAN bus.
The core devices of the pressure sensor of the utility model has been selected single silicon-chip design-calculated integrated pressure measured chip for use; Amplifying circuit and all compensation, output calibrating circuits are all concentrated in the silicon chip; Output characteristic according to its qualification; Peripheral circuit can carry out real-time diagnosis through its voltage and current data of monitoring.
The preferred version of the utility model is: aforesaid truck tanker sea cock and valve antitheft digital pressure sensor device based on the CAN bus; Said protective case seat shape and over cap match; Have inside groove on the border of said protective case seat, have boss on the said over cap border with said groove coupling.
Further, aforesaid truck tanker sea cock and valve antitheft digital pressure sensor device based on the CAN bus, said pressure sensor is installed on the cylinder of said sea cock and valve valve body.No matter adopt which kind of method to feed pressure, can both be detected to back down the sea cock and valve cylinder; And the sensor outside has protective case to cooperate, and after the protective case closure, just can not carry out any destruction to sensor, in case and protective case is opened, system will report to the police.
The beneficial effect of the utility model is: the utility model is under the prerequisite that keeps the original repertoire of truck tanker; According to explosion-proof criteria design circuit and structure; Make truck tanker transport safely and guard against theft monitoring effectively, simple, be suitable for, and be difficult to attacked and destroy.

The specific embodiment
Embodiment one
The truck tanker sea cock and valve antitheft digital pressure sensor device based on the CAN bus that present embodiment provides, basic structure such as Fig. 1 comprise that to shown in Figure 3 being fixed on sea cock and valve forms the protective case seat 3 of enclosing on every side and be connected the over cap 4 on the protective case seat; One side of protective case seat links to each other with over cap 4 through place's hinge 5 at least, is connected by lock bolt 6 again; On the cylinder 2 of the sea cock and valve valve body in the protective case seat pressure sensor 1 is installed, the test side of pressure sensor 1 is connected with sea cock and valve inside, and the signal output part of pressure sensor 1 is connected with the communication of exterior monitoring device through the CAN bus; Have inside groove 7 on the border of protective case seat, have boss 8 on the over cap border with the groove coupling.
The detecting device of present embodiment has been accomplished the continuous watch pressure changing in addition, can distinguish the cylinder action data under the different situations.Its resolution can reach more than 0.1 Kilogram Force Per Square Centimeter.Only if under situation about allowing, no matter adopt which kind of method to feed pressure to back down the sea cock and valve cylinder, all can be by timely discovery, system will report to the police immediately.The pressure sensor core devices has been selected single silicon-chip design-calculated integrated pressure measured chip for use, and amplifying circuit all concentrates in the silicon chip with all compensation, output calibrating circuits.According to the output characteristic of its qualification, peripheral circuit can carry out real-time diagnosis through its voltage and current data of monitoring.
As shown in Figure 4, be the fundamental diagram of intelligent pressure sensor device, the process that the MCU control presssure is measured is encrypted result of a measurement, and through the external communication of CAN bus; MCU detects the output characteristic control diagnostic procedure of IC simultaneously according to integrated pressure, through special Data Format Transform, make data can not directly express the characteristic of measurand.In addition, upper computer is also wanted the device characteristics data that dispose in the read sensor, and sensor is verified, reaches the purpose of encryption.
Above-mentioned diagnotic purpose is not victim simulation or destroys, and the fault of discovery in time itself.It is not simple pressure switch that integrated pressure detects IC, is difficult to use simple its output of method shielding.Selfdiagnosis is carried out according to the output characteristic that integrated pressure detects IC by MCU.Simultaneously can also carry out initial diagnostic by coupling system pressure, method is to regulate flow regulating valve to export different pressure, observes the pressure data of this sensor output, and both should be consistent.
Sensor is directly installed on the incorporate sea cock and valve cylinder, no matter adopt which kind of method to feed pressure to back down the sea cock and valve cylinder, can both be detected.And the sensor outside has protective case to cooperate, and after the protective case closure, just can not carry out any destruction to sensor.In case and protective case is opened, system will report to the police.
The characteristics of the utility model: the one, developed specially and detected the intelligent pressure sensor that state was opened/closed to the sea cock and valve cylinder, in the sea cock and valve cylinder position of truck tanker this sensor is installed, keep watch on the state of cylinder; The 2nd, adopt particular structural, and cooperation is protected with the protective case of belt transect intelligent transducer; The 3rd, adopted the CAN bus communication that possesses data encryption and self diagnostic capability to be connected through cooperating with sensor, make whole monitoring system all use the digital intelligent technology.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
