Problems solved by technology

[0007] The existing technologies all adopt a single in-position detection method, and its disadvantages are: 1. When the single in-position detection method fails, the detection cannot be continued; 2. When a fault occurs, it is impossible to judge the fault information

Embodiment 1

[0057] The present invention proposes a meter valve state detection method based on multi-signal fusion. When the valve is in the action state, it executes as figure 1 Steps shown:

[0058] Step 101: Perform mechanical in-position detection;

[0059] Step 102: Perform locked-rotor voltage detection after the mechanical in-position detection;

[0060] Step 103: Judging the valve in-position information according to the mechanical in-position detection result and the locked-rotor voltage detection result;

[0061] Step 104: When both the mechanical in-position signal and the locked-rotor voltage signal are detected, it is judged that the valve is in place at this time and is normal;

[0062] Step 105: When any one of the mechanical in-position signal and the locked-rotor voltage signal is not detected, judge the valve in-position fault information.

[0063] In the above-mentioned meter valve state detection method based on multi-signal fusion, the mechanical in-position detec...

Embodiment 2

[0097] The present invention proposes a meter valve state detection system based on multi-signal fusion, such as Figure 4 As shown, it includes the control unit, the mechanical in-position detection module for detecting the mechanical in-position detection module, the valve drive module for controlling the valve switch and the voltage in-position detection module for detecting the locked-rotor voltage. The control unit is connected with the mechanical in-position detection module to control The unit is connected with the voltage in-position detection module, and the control unit is connected with the valve driving module to control the valve driving module.

[0098] In the meter valve state detection system based on multi-signal fusion, the control unit can obtain the mechanical in-position detection result detected by the mechanical in-position detection module and the locked-rotor voltage detection result detected by the voltage in-position detection module, and then can acc...

Abstract

The invention aims at overcoming shortages in the prior art, and provides a metering valve state detection method and a metering valve state detection system based on multi-signal fusion. According to the metering valve state detection method based on multi-signal fusion, the following steps are executed when a valve is in an action state: carrying out mechanical in-place detection; carrying out locked-rotor voltage detection after the mechanical in-place detection; carrying out valve in-place information judgment according to a mechanical in-place detection result and a locked-rotor voltage detection result; judging that the valve is normally installed in place at this moment when both a mechanical in-place signal and a locked-rotor voltage signal are detected; and carrying out valve in-place fault information judgment when any of the mechanical in-place signal and the locked-rotor voltage signal is not detected. According to the metering valve state detection method and the metering valve state detection system based on multi-signal fusion, the two in-place detection manners are combined, and detection can be continued after one in-place detection is failed, so that the problem that detection cannot be continued after a single in-place detection manner is failed in the prior art is overcome, the stability of the in-place detection is improved, and the accuracy rate of the in-place detection is increased.

Description

technical field [0001] The invention relates to the field of valve detection, in particular to a multi-signal fusion-based meter valve state detection method and system. Background technique [0002] The valve is the executive part on the meter, which has the function of controlling the transmission of the medium. Its reliability is the basic guarantee for people's daily life. Whether the valve can be accurately in place after the operation is performed is the key to determining whether the meter can be used normally. If the expected in-position requirements are not met after the valve opening operation is performed, the pressure loss of the metering instrument will increase, resulting in a waste of resources. If the expected in-position requirements are not met after the valve closing operation is performed, there will be a risk of leakage of the transmission medium, resulting in an accident. Once an accident occurs, it will cause harm to people's health; if it is seriou...
