Abstract

The invention discloses a measurement control method of an orifice plate flowmeter, and the control method comprises the following steps: calculating the accurate flow rate, leading a microprocessor to control the power supply of a ZIGBEE wireless transceiving module, being ready to send data, leading a route to access all nodes in the polling way, leading the route to automatically receive the data and automatically queuing other nodes when the node uploads the data, and leading other nodes to automatically upload the data after the node uploading the data completes the data transmission; and repeating the uploading till the successful data uploading if the data uploading is not successful, and leading the route to send a completion signal to the node after the successful data uploading, and closing the ZIGBEE wireless transceiving module. The ZIGBEE wireless communication is adopted in the measurement control method, the measurement control method utilizes the advantages of automatic networking, and all the nodes are accessed in the polling way, thereby fully utilizing the time division multiplexing method, overcoming the problems of error and missing during the data uploading and ensuring the integrity of data.

Description

The measurement control method of orifice flowmeter

Technical field

The present invention relates to a kind of control method, relate in particular to a kind of measurement control method of orifice flowmeter.

Background technology

The drilling of now a lot of rock gases is on-the-spot, and environment is very complicated, abominable, and other disperse facility to form by many implications well, test satellite location, pipe manifold valve group, multi-purpose station, outer communication system etc. in a gas production field of natural-gas field; At present mostly by artificial quantitative check every day equipment operation situation and measure, the statistics gatherer data because gas well quantity is many and distribute extensively, labor strength is increased the weight of; And real-time, the accuracy of monitoring of tools and gas production data have been influenced; Hidden danger such as also have clerical mistake simultaneously, play tricks, and uploading in real time of data seems particularly important, at present; In some inflammable and explosive occasions, need pressure, temperature and other various signal in real time be uploaded; Need in time analyze etc. many flowmeters and other sensing data.

Existing flowmeter secondary instrument generally adopts serial communication or does not have communication, and in the rig-site utilization of complicacy, the client need upload the data to host computer and carry out analyzing and processing.Common serial port communication line often cause wiring inconvenience, security not high, be difficult to gather in real time and analyze problems such as data.

The ZIGBEE wireless telecommunications are emerging mechanicss of communication, and its advantage is can automatic network-building, but the ZIGBEE wireless telecommunications often run into the problem of loss of data, even in the world, the example of successful Application is also few.

Summary of the invention

The object of the invention just is that providing a kind of addresses the above problem, and data are difficult for losing, and can upload the measurement control method of the orifice flowmeter of data in real time.

To achieve these goals, the technical scheme of the present invention's employing is such: a kind of measurement control method of orifice flowmeter, said orifice flowmeter comprise a ZIGBEE radio receiving transmitting module, and its control method is:

Step 1: distinguish collecting temperature, pressure, differential pressure signal at interval through temperature sensor, pressure transducer and differential pressure pick-up, and calculate flow value accurately through microprocessor;

Step 2: after flowmeter was calculated accurately, the power supply of microprocessor control ZIGBEE radio receiving transmitting module was ready for sending data;

Step 3: route is visited each node with the mode of poll, and when this node had data upload, route was with the automatic reception data, and other node is lined up automatically, and when the node of uploading data was accomplished data transmission, other node was uploaded automatically again; If data upload is unsuccessful, repeat to upload until the data upload success;

Step 4: after the data upload success, route is sent and is accomplished signal to node, closes the ZIGBEE radio receiving transmitting module.

Compared with prior art, the invention has the advantages that: adopt the ZIGBEE wireless telecommunications, utilized the advantage of its automatic network-building, simultaneously; Adopt the mode of poll to visit each node, after node added, route searched new node, and adds to node in the network automatically; When a node was given route with data upload, other node was lined up automatically, and when the node of uploading data was accomplished data transmission, other node was uploaded automatically again; Made full use of time-multiplexed method, overcome the problem of makeing mistakes, omitting of data upload, guaranteed the integrality of data, and ZIGBEE adopts free frequency range to carry out data transmission; After networking, need not other any expense, cheap, after node data is uploaded successfully; Route will be sent one and accomplished signal to node, close the ZIGBEE radio receiving transmitting module, further reduce power consumption.

Embodiment

Embodiment:

A kind of measurement control method of orifice flowmeter, said orifice flowmeter comprise a ZIGBEE radio receiving transmitting module, and said ZIGBEE radio receiving transmitting module links to each other with the serial port of microprocessor through its serial port, and its control method is:

Step 1: distinguish collecting temperature, pressure, differential pressure signal at interval through temperature sensor, pressure transducer and differential pressure pick-up, and calculate flow value accurately through microprocessor;

Step 2: after flowmeter was calculated accurately, the power supply of microprocessor control ZIGBEE radio receiving transmitting module was ready for sending data;

Step 3: route is visited each node with the mode of poll, and when this node had data upload, route was with the automatic reception data, and other node is lined up automatically, and when the node of uploading data was accomplished data transmission, other node was uploaded automatically again; If data upload is unsuccessful, repeat to upload until the data upload success;

Step 4: after the data upload success, route is sent and is accomplished signal to node, closes the ZIGBEE radio receiving transmitting module.

The ZIGBEE radio receiving transmitting module obtains microprocessor control signal through serial port, can realize functions such as automatic network-building, data upload, and is very convenient; Simultaneously, adopt the mode of poll to visit each node, after node added, route searched new node; And node added in the network automatically, when a node was given route with data upload, other node was lined up automatically, when the node of uploading data is accomplished data transmission; Other node is uploaded automatically again, has made full use of time-multiplexed method, has overcome the problem of makeing mistakes, omitting of data upload; Guaranteed the integrality of data, and ZIGBEE adopts free frequency range to carry out data transmission, after networking; Need not other any expense, cheap, after node data is uploaded successfully; Route will be sent one and accomplished signal to node, close the ZIGBEE radio receiving transmitting module, further reduce power consumption.
