Vibrating wire sensor is exposed to for a long time in air or buries underground with concrete, and therefore, temperature impact is notable, in test process, rejects the strain part of temperature impact, temperature is affected error and is modified, obtain real structural stress state, be a crucial job.
In actual applications, vibrating wire sensor is internally installed temperature sensor, for monitoring operating temperature and the temperature-compensating of sensor, but different sensor producers, use temperature sensor and differ, mainly include two class temperature sensors, one class is digital temperature sensor (temperature sensor DS18B20), also having a class is analog temperature sensor, and typically vibrating wire acquirer only supports the collection of a class temperature sensor, the scope of application that so can cause vibrating wire acquirer reduces, do not possesses good compatibility, for using the vibrating wire sensor of different manufacturers, need to use different vibrating wire acquirers that it is gathered, make troubles to onsite application.
Summary of the invention
For above-mentioned problem, this utility model patent purpose is to solve vibrating wire acquirer can not the problem of compatible different manufacturers sensor, possessing the function automatically identifying temperature sensor, all can gather data for digital temperature sensor and analog temperature sensor, onsite application is very convenient.
To achieve these goals, this utility model adopts the following technical scheme that
The vibrating wire acquirer that a kind of temperature sensor identifies automatically, it includes exciting circuit, signal acquisition circuit, temperature collection circuit, single chip control module, communication module；
Above-mentioned exciting circuit, signal acquisition circuit, temperature collection circuit are connected with vibrating wire sensor；
Above-mentioned exciting circuit, signal acquisition circuit, temperature collection circuit are connected with communication module by single chip control module.
When using vibrating wire acquirer to gather vibrating wire sensor, Single-chip Controlling opens high-pressure modular, produces the high pressure of a 30V, then Single-chip Controlling exciting circuit, sends pumping signal.Then switching signal Acquisition Circuit, is processed the data input single-chip microcomputer gathered by AD conversion, and the data of collection are carried out FFT calculating, obtain frequency values by single-chip microcomputer.After frequency acquisition completes, then Single-chip Controlling temperature collection circuit, first passes through circuit and single-chip microcomputer judges whether temperature sensor is digital temperature sensor, if digital temperature sensor, single-chip microcomputer, directly by specific sequential, reads temperature value.If it is determined that be not numeric type temperature sensor, analog temperature Acquisition Circuit opened by single-chip microcomputer, reads temperature value.When reading temperature, it is not necessary to arrange the temperature sensor type of vibrating wire acquirer, vibrating wire acquirer can read temperature value according to the sensor automatic decision connected, and onsite application is convenient, has compatible with property.After obtaining frequency and temperature by vibrating wire acquirer, vibrating wire acquirer, according to the temperature adjustmemt K value arranged, carries out temperature foh correction automatically, is then calculated real force value, rejects the temperature impact on gathering data.
The beneficial effects of the utility model:
This utility model solves the problem that vibrating wire acquirer gathers two kinds of dissimilar temperature sensors simultaneously, and can automatically identify the temperature sensor type within vibrating wire sensor, corresponding Acquisition Circuit collecting temperature value is selected, it is achieved vibrating wire sensor automatic temperature-adjusting correction according to different temperature sensors.
