Abstract
The invention discloses a real-time monitoring method for a natural gas station. A lower computer is arranged and connected with all flow meters in the station through wires. The lower computer is provided with a wind power detector and a rain gauge, and the lower computer can judge real-time wind power and rainfall. When the wind power and the rainfall are below the limit, the lower computer can collect data of the flow meters every other hour and send the data to a monitoring center. When the wind power or the rainfall is beyond the limit, the lower computer can collect the data of the flow meters every other five minutes and send the data to the monitoring center. The real-time monitoring method has the advantages that a monitoring terminal can test the weather conditions, the frequency of sending the monitoring data is low when the weather is good to guarantee that a communication channel of the monitoring center is not busy; the frequency of sending the monitoring data is increased under the severe whether in which problems easily occur to guarantee that a monitoring person can know the conditions in time when the conditions occur.
Description
Technical field
The present invention relates to rock gas method for supervising, particularly relate to a kind of natural gas station method for real-time monitoring.
Background technology
In rock gas transmission, a battlefield monitoring generally all can be set combustion gas is divided when defeated, in case point defeated flow is not right, cause that to be transported to client's combustion gas air pressure not right, there is so sometimes unpredictable accident, because becoming the instrument greatly client being used, combustion gas air pressure has very large pressure, when excessive, may cause these instrument damage, phenomenon even leaks air, gas monitor and control is extremely important, in existing gas monitor and control, need monitor staff to obtain data on flows in control end transmitted signal, not only waste of manpower, and easily there is carelessness in artificial monitoring, thereby do not monitor the generation of accident, cause very large loss.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of natural gas station method for real-time monitoring is provided, solving existing station farm monitoring system needs people for monitoring data on flows, waste of manpower, and the defect of easily neglecting.
The present invention is achieved through the following technical solutions: natural gas station method for real-time monitoring, comprises the following steps:
(1) slave computer is set by all flowmeters in field, connection station, on described slave computer, is provided with wind-force detector and rain gage, make slave computer can judge real-time wind-force and rainfall;
(2), in the time that wind-force and rainfall are all under boundary, slave computer can be collected at interval the data of a flowmeter for 1 hour, after storage, then sends to Surveillance center by wireless signal; In the time that wind-force or rainfall break bounds, the data that slave computer can interval be collected a flowmeter for 5 minutes, after storage, then send to Surveillance center by wireless signal;
(3) Surveillance center receives after the signal of slave computer transmission, can send a confirmation signal to slave computer, and in the time that slave computer was not received confirmation signal in five minutes, slave computer can resend once the signal sending in the first five minute;
(4) when slave computer is not received after confirmation signal at accumulative total set point number, can send warning to a station keeper by circuit, by keeper, slave computer is keeped in repair.
Method for supervising of the present invention, that monitor terminal sends data to Surveillance center automatically, then automatic alarm, do not need monitor staff constantly to stare at monitoring screen, save manpower, and monitor terminal can be tested wind-force and rainfall, be in the time of good weather, the frequency of transmitted traffic signal is lower, 1 hour once, save the electric energy of monitor terminal, make its service time elongated, and the communication channel taking is few, between multiple monitor terminals, impact is very little, but while there is wind and rain weather at this monitor terminal place, it can continuous test traffic, can send and once monitor form at 5 minutes, control and monitoring are ensured, can occur after situation, monitor staff can know at once, and Surveillance center is receiving that form can send confirmation signal, make slave computer know its transmitted signal and be effectively sent to Surveillance center, when after slave computer sends signal, do not receive confirmation signal half an hour, can again send the signal of last time, until receive confirmation signal, but repeatedly do not receiving after confirmation signal, this may be repeatedly continuous can be also interval, in slave computer, having counter counts, after being generally 5 times, send the staff of caution signal to gas station field, staff can come once to overhaul, check and whether go wrong.
In method of the present invention, also comprise a clock synchronous step: when slave computer transmits a signal to Surveillance center, can in signal, add real time clock parameter, whether the clock that Surveillance center judges slave computer according to this real time clock parameter is synchronous, as asynchronous, in transmission confirmation signal, also can insert own real time clock parameter, slave computer can calculate the mistiming with Surveillance center according to the delay parameter of this real time clock parameter and setting, thereby refresh clock reaches clock synchronous.
The invention has the beneficial effects as follows: monitor terminal can be tested weather condition, in the time of good weather, the frequency that sends monitor data is lower, ensure that Surveillance center's communication channel is not busy, in the time of the inclement weather easily going wrong, improve and send monitor data frequency, ensure in the time there is situation, monitor staff can know in time.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
Natural gas station method for real-time monitoring, comprises the following steps:
