Technical Field

Background
When the gas system is in construction, the serious consequences can be caused when the gas pressure is higher or lower than the safety range. Thus requiring multiple monitoring of gas pressure at the site. One prior art is to connect a water column meter to a gas pipeline, manually monitor the pressure (water column) change, and inform a responsible person at a pressure control position to adjust the pressure through other communication means such as a telephone, which consumes manpower and is easy to miss or delay reporting when the pressure is abnormal.
Another prior art is to couple a pressure sensor to a gas pipeline, send a signal to a control system after detecting a pressure change, and warn a centralized control room or a field worker by the control system in a manner of sound, flashing, or color change. However, the construction site of the gas pipeline usually has many personnel and mechanical equipment, the noise decibel of speaking personnel or mechanical operation is high, and the audio alarm sound of the commonly used alarm device is small and is easily covered by site noise. On the other hand, if pipeline cutting is required on the operation site or in an environment with strong outdoor sunlight irradiation, the active luminous intensity of a common alarm device is limited, and the problem of visual angle deviation also exists, so that the common alarm device is easily ignored by operators. Further, if the intensity of the audio or video alarm needs to be further improved, the volume and the energy consumption of the corresponding alarm device need to be increased correspondingly, and the cost is also increased rapidly. If the data needs to be remotely transmitted to the control center for adjustment, the control center often monitors the gas leakage conditions at multiple positions at the same time, and the pressure of operators is increased invisibly when corresponding alarms are accurately and timely found in numerous alarm interfaces.

Drawings
The technical solution of the present invention is explained in detail below with reference to the accompanying drawings, in which:
fig. 1 shows a block diagram of a gas pressure warning system according to an embodiment of the invention.
Detailed Description
The features and technical effects of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and with reference to exemplary embodiments, which disclose a pressure alarm system that can be effective and low-cost in a complex working environment. It is noted that like reference numerals refer to like structures and that the terms "first", "second", "upper", "lower", and the like as used herein may be used to modify various structures. These modifications do not imply a spatial, sequential, or hierarchical relationship to the structures being modified unless specifically stated.
As shown in fig. 1, the gas pressure alarm system according to the embodiment includes a pressure sensor coupled to a gas pipe, for example, at least partially buried in the gas pipe or a dedicated test pipe connected to the gas pipe, and may be installed on an outer wall of the gas pipe, for measuring the gas pressure in real time at a pipe installation site. The pressure sensor collects pressure values at regular intervals, for example 5 seconds, and converts the pressure variations into analog electrical signals, typically of a magnitude between 0 and 100mV, using a piezoelectric membrane.
The environmental sensors are installed at least at the construction site and preferably also simultaneously in the remote control center for monitoring environmental parameters at the construction site or at the remote control center in real time. The environmental parameters include at least the sound intensity (e.g., decibels) and the illumination intensity (e.g., lumens) of the environment, and may further include temperature (e.g., degrees celsius) and humidity (e.g., percentage). The environmental sensor can adopt a sleep mode, and the parameters of the field environment are detected within a certain time interval, such as 0.1-1 second, only when the output change of the pressure sensor exceeds a threshold value, so that the power consumption can be reduced, and the total working time can be prolonged. The output of the environmental sensor is also an analog signal.
At least one, e.g., a first, input of an analog-to-digital (AD) converter is connected to the output of the pressure sensor for converting the analog electrical signal measured by the pressure sensor to a digital electrical signal and sending it to the system controller. At least one other, e.g., second, input of the AD converter is connected to the output of the environmental sensor to convert the analog signal of the environmental sensor into a digital electrical signal to be sent to the system controller. The communication interface between the AD converter and the system controller is, for example, a 485 interface.
And the system controller receives the pressure value transmitted by the pressure sensor from the AD converter, compares the pressure value with a preset pressure threshold value stored in the controller, and starts an alarm process if the pressure value exceeds the threshold value. Subsequently, the system sensor compares the environmental parameter transmitted by the AD converter with a pre-stored environmental threshold (e.g. sound intensity threshold, light intensity threshold), searches for and activates a tactile alarm worn by the operator at the construction site or at the remote control center if the environmental threshold is exceeded, or else activates only an audio alarm (e.g. emits a specific sound through a speaker) or a visual alarm (e.g. emits a specific color light through a lamp or flashes of a control light). The tactile alarm may be a dedicated wearable device such as a bracelet, collar, pendant, etc. that generates regular vibrations through a motor driven eccentric to alert the operator. The tactile alarm can also be a smart phone carried by an operator, and the system is communicated with a program (app) pre-installed in the mobile phone so as to start a vibration motor carried by the mobile phone. In harsh operating environments, such as extreme air temperatures or climates, the operator's auditory, visual, and tactile sensations may be reduced to some extent by clothing wrapping. To cope with such a harsh operating environment, the tactile alarm may also be a pain sensation stimulating device worn close to the body, such as a lancet or an electrode, which ensures the effectiveness of the alarm by using the sensitivity of the operator to the pain sensation.
The system controller may be various control logic, such as hardware like ASIC, FPGA, etc., firmware integrated in the pressure sensor, environmental sensor, tactile alarm, or software running on the control center host, server, or operator handset. In one embodiment, the gas pressure alarm system is a box-type device arranged on a construction site, adopts a stainless steel shell which can be portable, quickly opened, shockproof and waterproof, adopts a lithium battery for power supply inside, and can normally work at the low temperature of minus 30 ℃.
According to the utility model discloses gas pressure alarm system prefers to select touch alarm mode when the environmental sensor reading exceeds the threshold value, can effectively just provide pressure warning with low costs under complicated operational environment.
While the invention has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the disclosed system architecture and method of manufacture will include all embodiments falling within the scope of the invention.
