Problems solved by technology

However, a single sampling method will lead to inaccurate sampling of the sampling signal when receiving an interference signal, which will affect the sampling accuracy, and even cause missing or interruption, resulting in inaccurate flow measurement. At the same time, a single sampling method cannot realize the calibration of the sampling signal , low reliability

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] refer to figure 1 , this figure is a schematic flow chart of the first embodiment of the sampling method of a flow detection instrument of the present invention, including the following steps:

[0030] Step s1, the first signal receiver receives the first signal from the first signal generator and transmits the first signal to the main control unit;

[0031] Step s2, the main control unit determines the current position status of the metering code disc according to the first signal;

[0032] Step s3, when the main control unit determines that there is interference in the first signal according to receiving the first signal, control the second signal generator to send a second signal;

[0033] Step s4, the second signal receiver transmits the second signal to the main control unit;

[0034] In step s5, the main control unit determines the current position st...

Abstract

The invention discloses a sampling device for a flow measurement instrument. The sampling device comprises a measurement code disk, a control device, a first signal generator and a second signal generator, wherein the control device comprises a main control unit, a first signal receiving unit and a second signal receiving unit. The sampling device is characterized in that the first signal receiving unit is used for receiving a signal sent by the first signal generator and transmitting the signal to the main control unit; the main control unit is used for judging whether the first signal is interfered or not; if yes, the second signal generator is activated to detect a position state of the measurement code disk; and if not, the current position state of the measurement code disk is determined according to the received first signal and stored. In addition, the invention further discloses a sampling method for the flow measurement instrument. The sampling reliability of the sampling device for the flow measurement instrument is improved, and the sampling interruption is avoided.

Description

technical field [0001] The invention relates to the technical field of flow measuring instruments, in particular to a sampling device for a flow measuring instrument and a sampling method thereof. Background technique [0002] At present, in the field of flow measurement instrument (such as gas meter) sampling technology, a single signal sampling measurement method is usually used. For example, in the prior art, Hall sensors are used to collect magnetic signals to sample the flow of technical fluids, which has power consumption low feature. However, a single sampling method will lead to inaccurate sampling of the sampling signal when receiving an interference signal, which will affect the sampling accuracy, and even cause missing or interruption, resulting in inaccurate flow measurement. At the same time, a single sampling method cannot realize the calibration of the sampling signal , low reliability. Contents of the invention [0003] The object of the present invention...
