Embodiment 1
[0029] The embodiment of the present invention provides a conversion valve fault early warning method, which is applied to monitor and convert the valve repair on the ceramics stage loop parameters. figure 1As shown, the switching valve is composed of a plurality of bridge arms, and each bridge arm has a plurality of thyristor level circuits connected in series, each thyristor trigger monitoring unit is connected to a thyristor, and the thyristor trigger monitoring unit is used for pairs The trigger control, protection and operation of the thyristor, wherein the operating state monitoring function mainly includes information that triggers the monitoring unit, the thyristor protection trigger state, and the thyristor fault state, and feeds back to the upper layer monitoring system by returning the signal Fiber Channel. Such as valve-based electronic equipment, such as figure 2 As shown, the fault early warning method includes:
[0030] Step S11: Receiving the return signal transmit...
Embodiment 2
[0057] The embodiment of the present invention provides a converged valve fault warning system, such as Figure 5 As shown, including:
[0058] The return signal module 1 is used to receive the return signal transmitted by each thyristor trigger monitor, and each rendering signal is compared to the preset return signal to obtain the initial time time of each rendering signal and the preset return signal; this module The method described in step S11 in Example 1 is not described herein again.
[0059] The parameter discriminator 2 determines that the thyristor stage loop parameter corresponding to the rendering signal is determined if the rendering signal is reached when the rendered time difference threshold is reached in the preset time difference threshold. The method is not described herein.
[0060] The fault discriminant module 3 is configured to detect the parameters of each element in the thyristor stage circuit of the parameter change. When the amount of variations of each ...
Embodiment 3
[0062] The embodiment of the present invention provides a computer device, such as Image 6As shown, at least one processor 401, such as a CPU (Central Processing Unit, central processor), at least one communication interface 403, memory 404, at least one communication bus 402. The communication bus 402 is used to implement connection communication between these components. Here, communication interface 403 can include a display, a keyboard, and optional communication interface 403 can also include a standard wired interface, a wireless interface. Memory 404 can be a high speed RAM memory (Ramdom Access Memory, volatile random access memory), or a non-Volatile Memory, such as at least one disk memory. Memory 404 can also be an at least one storage device located away from the processor 401. The processor 401 can perform the conversion valve fault early warning method of Example 1. The memory 404 stores a set of program code, and the processor 401 calls the program code stored in th...
