Abstract
The invention discloses a pressure detecting system of a gas storage tank, which comprises a pressure sensor, an analog/digital (A/D) converting module, a micro-processor module and a pressure display module, wherein the pressure sensor, the A/D converting module, the micro-processor module and the pressure display module are sequentially connected, and the micro-processor module is further connected with an alarm module. The pressure detecting system solves the problems in the prior art that requirements for gas storage tank working staff are high and reliability is not high. The pressure display module displays collected pressure information in the gas storage tank in real time, collected parameters are compared with a set alerting value, when a collected value is larger than the alerting value, alarm is produced to remind working staff, so that safety accidents are prevented from happening, and reliability of system operation is improved through a circuit detecting module.
Description
Technical field
The present invention relates to a kind of pressure detecting system, especially a kind of gas holder pressure detecting system.
Background technique
In the production process of all gases such as nitrogen, oxygen; Gas holder is a kind of imperative equipment, and is a significant process of safety in production to the monitoring of gas holder internal pressure, and all this has the pressure-display instrument usually on the existing gas holder; Show the pressure in the gas holder in real time; So that staff's reference, but this gas holder needs staff's observed pressure Displaying Meter always, and sight line has transfer just might cause potential safety hazard slightly; Not only very high to staff's requirement, and reliability is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of gas holder pressure detecting system, not only can show the pressure in the gas holder in real time, and when pressure surpasses warning line, can guarantee the Security of producing through alarm module caution staff.
In order to solve the problems of the technologies described above, the technological scheme that the present invention adopted is:
A kind of gas holder pressure detecting system comprises the pressure transducer, A/D modular converter, microprocessor module and the pressure display module that connect successively, also is connected with alarm module on the said microprocessor module.
Aforesaid gas holder pressure detecting system is characterized in that: also be connected with the circuit supervision module on the said microprocessor module.
Aforesaid gas holder pressure detecting system is characterized in that: also be connected with the signal condition module between said A/D modular converter and the microprocessor module.
The invention has the beneficial effects as follows: show the pressure information in the gas holder that pressure transducer collects in real time through pressure display module; And the warning value of parameter that collects and setting compared; When the numerical value that collects gives the alarm during greater than warning value; Remind the staff, avoided the generation of security incident, improved reliability of system operation through the electric circuit inspection module.
Description of drawings
Fig. 1 is that the module of gas holder pressure detecting system of the present invention connects schematic representation.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of gas holder pressure detecting system; Comprise the pressure transducer, A/D modular converter, microprocessor module and the pressure display module that connect successively; Also be connected with alarm module on the said microprocessor module, also be connected with the circuit supervision module on the said microprocessor module, also be connected with the signal condition module between said A/D modular converter and the microprocessor module.
The analog amount of the gas holder internal pressure of pressure transducer collection converts into behind the digital quantity through being input to microprocessor module after the signal condition resume module through the A/D modular converter; And the data of gathering are shown through pressure display module; Warning numerical value with data that collect and setting compares simultaneously; When being higher than the numerical value of setting, sound the alarm through alarm module, remind operator to take appropriate measures.Operation through circuit supervision module monitors whole system simultaneously; Avoid the program of system to get into endless loop; Cause system normally to move, the chip that circuit supervision module of the present invention is adopted is the X25045 chip, and it integrates EEPROM, WatchDog Timer, three kinds of functions of voltage monitoring; Simplify circuit design, improved the reliability of system.
In sum, a kind of gas holder pressure detecting system provided by the invention not only can show the pressure in the gas holder in real time, and when pressure surpasses warning line, can guarantee the Security of producing through alarm module caution staff.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
