All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment 1 of the invention provides an equipment electric leakage detection method which is applied to an electric leakage detection system. Fig. 1 is a schematic flow chart of an apparatus leakage detection method in embodiment 1 of the present invention, and as shown in fig. 1, the apparatus leakage detection method in embodiment 1 of the present invention includes the following steps:
s101: an electrical signal is acquired.
In the embodiment of the invention, the leakage protection system comprises an electric signal collector and a controller connected with the electric signal collector. As a specific implementation manner, in embodiment 1 of the present invention, the electrical signal includes a voltage signal and a current signal, and the corresponding electrical signal collector is a voltage sensor and a current sensor. In the embodiment of the invention, the voltage sensor and the current sensor can be arranged alternatively or simultaneously.
S102: and determining whether the electric leakage detection system is in a normal working state according to whether the electric signal is effective.
The electric leakage detection system may be abnormal in the use process, i.e. not in a normal working state, for example, the voltage sensor and/or the current sensor are damaged; the connection between the voltage sensor and/or the current sensor and the controller is disconnected. In the embodiment of the present invention, the step S102 is set to detect whether the electric leakage detecting system is abnormal or not by determining whether the electric signal is valid or not.
As a specific implementation manner, the following technical solution may be adopted to determine whether the electrical leakage detection system is in a normal operating state according to whether the electrical signal is valid.
Scheme 1: and judging whether the acquired electric signal is an effective electric signal or not, and judging that the electric leakage detection system is in a normal working state when the acquired electric signal is the effective electric signal. When the scheme 1 is adopted, the operating state of the electric leakage detection system can be determined quickly.
Scheme 2: judging whether the obtained electric signals are effective electric signals, counting the number of the effective electric signals obtained in a preset time period, and judging that the electric leakage detection system is in a normal working state when the number is larger than a first preset threshold value. When the scheme 2 is adopted, the condition that the electric signal is invalid due to accidental factors can be eliminated, so that the working state of the electric leakage detection system can be determined more accurately.
As a specific implementation manner, it may be determined whether the voltage or the current of the signal collector is zero, and if not, the voltage or the current is an effective electrical signal. For example, in many electronic devices, the determination of whether an electric signal is valid is performed using a voltage value, which may be an instantaneous voltage.
S103: and when the electric leakage detection system is in a normal working state, determining whether the equipment leaks electricity according to the numerical value of the effective electric signal.
In embodiment 1 of the present invention, the apparatus may be an industrial robot, for example.
As a specific implementation manner, the following technical scheme can be adopted for determining whether the device is in leakage according to the value of the effective electric signal.
Scheme 3: and determining the value of the obtained effective electric signal, and judging the electric leakage of the equipment when the value is larger than a second preset threshold value.
Scheme 4: and calculating the average value of the effective electric signals in the preset time period, and judging the electric leakage of the equipment when the average value is greater than a second preset threshold value.
In the embodiment of the present invention, the second preset threshold may be obtained by: collecting instantaneous electric signals of the ground wire or the shell of the equipment; determining the second preset threshold value according to the instantaneous electric signal. Wherein, the instantaneous electrical signal is an electrical signal detected on the ground wire or the casing of the device when an electrical leakage condition occurs, and the voltage sensor for detecting the electrical signal on the ground wire or the casing of the device and the voltage sensor for acquiring the electrical signal in the step S101 are the same voltage sensor; the current sensor that detects the electrical signal on the device ground or housing is the same current sensor that acquired the electrical signal in step S101.
Further, when the electric leakage detection system is not in a normal working state, an alarm instruction of the electric leakage detection system is sent out. Therefore, the user can check the electric leakage detection system in an abnormal condition in time and eliminate the abnormality. Furthermore, when the electric leakage detection system is not in a normal working state, a power-off instruction of a main power supply (namely a power line) of the equipment is also sent. Therefore, when the electric leakage detection system is abnormal, the situation that electric leakage occurs but is not detected is avoided, and the life safety of workers is ensured.
