Abstract
The utility model discloses a wireless pressure monitoring alarm which is capable of monitoring the pressure of a pipeline in real time. With the wireless pressure monitoring alarm, an upper limit value and a lower limit value are set by an electro connecting pressure gauge in advance, when pressure change surpasses the upper limit value or the lower limit value, the change can be processed by a pressure signal processing circuit and emitted to a signal receiving circuit by a pressure signal emitting circuit, and finally a monitoring display circuit is ordered to alarm, thereby realizing the real-time and wireless monitoring on the pressure of the pipeline. The wireless pressure monitoring alarm can be applicable to the various pipeline transportation fields.
Description
Technical field
The utility model relates to a kind of line pressure supervisory device.
Background technique
The on-the-spot oil gas of petroleum production from individual well to the defeated process of metering station collection because the wild environment complexity, the factor that influences the flow process line pressure variations is more, pressure surge changes greatly.
At present individual well to the pressure monitor of metering station is extensively adopted the mode of artificial on-the-spot inspection, will bring very big workload to the workman like this, and the phenomenon that may exist variation in pressure in time not find, thereby it is defeated to influence the oil gas proper set.
The model utility content
At the defective that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of pressure monitor wireless alarm that can monitor in real time line pressure.
The technical solution of the utility model is as follows: the pressure monitor wireless alarm, comprise pressure gauge with electric contact 1, pressure signal processing circuit 2, pressure signal emitting circuit 3, signal receiving circuit 4, signal evaluation circuit 5, monitoring display circuit 6, pressure gauge with electric contact 1 is provided with upper limit value and lower limit value, be connected with pressure signal processing circuit 2, signal after treatment is by signal transmission circuit 3, give signal evaluation circuit 5 behind signal receiving circuit 4 receiving demodulations, analysis circuit is judged upward limited signal or limited signal post command monitoring display circuit 6 warnings down.
The beneficial effects of the utility model are, pressure gauge with electric contact 1 sets upper limit value and lower limit value in advance, variation in pressure appears above after the upper limit value and lower limit value, can be transmitted to signal receiving circuit 4 by pressure signal processing circuit 2 processing, pressure signal emitting circuit 3, final order monitoring display circuit 6 is reported to the police, realization is in time judged incidents such as plugging line, stolen to the real-time radio monitoring of line pressure according to force value, thereby assurance oil-gas gathering and transportation is normally carried out.
Description of drawings
Fig. 1 is a signal flow graph of the present utility model.
Embodiment
As shown in Figure 1, pressure gauge with electric contact 1 is installed on the pipeline, set the upper limit value and lower limit value of electric contact, circuit part is connected with pressure signal processing circuit 2 by signaling line, when the flow process line pressure surpasses setting value, pressure gauge with electric contact 1 just carries a level signal to give pressure signal processing circuit 2, the signal receiving circuit 4 that signal is after treatment sent to the form of radio waves by signal transmission circuit 3.Receiving circuit is given signal evaluation circuit 5 with the signal of demodulation, and analysis circuit is judged upward limited signal or limited signal post command monitoring display circuit 6 warnings down.
