Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0033] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0034] First, let's explain the terms used in this application: UART communication protocol: Universal Asynchronous Receiver / Transmitter, is an asynchronous serial communication protocol that does not require a synchronous clock signal; CAN bus: Controller Area Network Bus, is a multi-master, serial, asynchronous fieldbus communication protocol that supports distributed real-time data transmission between devices; IIC bus: Inter-Integrated Circuit Bus, is a half-duplex, synchronous serial communication bus.

[0035] In high-density computing scenarios, the high-power electronic components of devices (such as servers) generate dense heat. Phase change liquid cooling technology, which involves directly introducing coolant into the device's (e.g., server's) cavity and utilizing the coolant's heat absorption and phase change (e.g., liquid to gas) to remove heat, achieves overall cooling of the device (e.g., server). Such devices utilizing phase change liquid cooling technology are called liquid-cooled devices (e.g., liquid-cooled servers). In related technologies, the opening and closing of solenoid valves is often controlled based on data collected by sensors to ensure the amount of coolant in the device's (e.g., server's) cavity. However, these technologies suffer from the inability to detect whether the solenoid valve is malfunctioning.

[0036] To address the aforementioned technical problems, this application proposes the following technical concept: a valve control and status detection circuit for a liquid cooling device, comprising at least a control processing module and a valve control board; firstly, the control processing module collects intracavitary environmental data within the liquid cooling device via sensors and generates a pulse width modulation signal based on a preset algorithm; subsequently, the valve control board controls the valve opening / closing state of the solenoid valve via a solenoid valve drive circuit according to the pulse width modulation signal; finally, the control processing module also collects the real-time valve status voltage of the solenoid valve and generates a valve status result based on the real-time valve status voltage; wherein, the real-time valve status voltage corresponds to the valve opening / closing state; the valve status result is used to indicate whether the solenoid valve is faulty; thus solving the problem that related technologies cannot identify whether the solenoid valve is faulty.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Figure 1 This is a schematic diagram of the valve control and status detection circuit of the liquid cooling equipment provided in the embodiments of this application. Figure 1 .

[0039] like Figure 1 As shown, the valve control and status detection circuit of the liquid cooling equipment includes: a control processing module 100, and sensors 200, valve control board 300, and baseboard management controller 400, which are respectively communicatively connected to the control processing module 100; the valve control board 300 includes a solenoid valve 500.

[0040] The sensor 200 is used to collect the internal environment data of the liquid cooling device 600; the control processing module 100 is used to generate a pulse width modulation signal based on the internal environment data, and control the valve opening and closing state of the solenoid valve 500 through the valve control board 300.

[0041] The control processing module 100 is also used to collect the real-time valve status voltage of the solenoid valve 500 and generate valve status results based on the real-time valve status voltage; the real-time valve status voltage has a corresponding relationship with the valve opening and closing status.

[0042] The baseboard management controller 400 is used to receive the valve status results sent by the control processing module 100, and generate normal valve operation information or valve abnormality alarm information based on the valve status results.

[0043] For example, the control processing module 100 generates the valve state result of the solenoid valve 500 by comparing the real-time valve state voltage with voltage range thresholds; wherein, the voltage range thresholds include valve open state voltage range thresholds, valve closed state voltage range thresholds, coil short circuit state voltage range thresholds, coil burnout state voltage range thresholds, and mechanical jamming state voltage range thresholds. Further, the voltage range thresholds are used to indicate the valve state within a preset voltage range; for example, the valve open state voltage range threshold is 1.5V~2.0V, the coil short circuit state voltage range threshold is 0~0.5V, and the mechanical jamming state voltage range threshold is 0.8V~1.2V.

[0044] Specifically, the control processing module 100 collects the real-time valve status voltage of the solenoid valve 500 and compares it with a preset voltage range threshold. When the real-time valve status voltage is within the open valve state voltage range threshold, the solenoid valve 500 is determined to be in the open valve state, and the valve status result is open valve state; when the real-time valve status voltage is within the coil short circuit voltage range threshold, the solenoid valve 500 is determined to have a coil short circuit fault, and the valve status result is coil short circuit fault; when the real-time valve status voltage is within the mechanical jamming voltage range threshold, the solenoid valve 500 is determined to have a mechanical jamming fault, and the valve status result is mechanical jamming fault.

[0045] The baseboard management controller 400 generates normal valve operation information or valve abnormality alarm information based on the valve status results. If normal valve operation information is generated, a valve operation report is generated based on a preset time period. If valve abnormality alarm information is generated, a valve alarm notification is sent to the user to inform the user that the solenoid valve is faulty. Furthermore, the baseboard management controller 400 can also receive solenoid valve control commands input by the user through an interactive device. The baseboard management controller 400 then sends the solenoid valve control commands to the main control processor 101, so that the main control processor 101 generates corresponding valve control commands based on the solenoid valve control commands, thereby controlling the opening / closing of the corresponding solenoid valve. This allows the user to remotely control the opening / closing of the solenoid valve through the baseboard management controller 400. The remote reporting mechanism of the baseboard management controller shortens the fault response time of the solenoid valve and reduces the risk of downtime of the liquid cooling equipment due to failure to detect valve faults in a timely manner or failure to replace faulty valves in a timely manner.

[0046] In this embodiment, the control processing module generates a pulse width modulation signal based on the intracavity environmental data collected by the sensor, and then controls the valve opening and closing state of the corresponding solenoid valve through the valve control board. Furthermore, the control processing module collects the real-time valve status voltage of the solenoid valve and generates a valve status result based on the real-time valve status voltage; the real-time valve status voltage corresponds to the valve opening and closing state; the valve status result is used to indicate whether the solenoid valve is faulty. The ground board management controller receives the valve status result sent by the control processing module and generates normal valve operation information or valve abnormality alarm information based on the valve status result; this solves the problem that related technologies cannot identify whether the solenoid valve is faulty.

[0047] Figure 2 A schematic diagram of the valve control and status detection circuit of the liquid cooling equipment provided in the embodiments of this application. Figure 2 ,like Figure 2 As shown, in Figure 1 Based on the embodiments, the control processing module 100 includes a main control processor 101, a dedicated processor 102, an analog switch array 103, and a programmable controller 104; the valve control board 300 includes multiple solenoid valve drive circuits 700.

[0048] The main control processor 101 is communicatively connected to the sensor 200, the programmable controller 104, the dedicated processor 102, and the baseboard management controller 400. The programmable controller 104 is communicatively connected to the valve control board 300 through each solenoid valve drive circuit 700. The dedicated processor 102 is communicatively connected to each solenoid valve drive circuit 700 of the valve control board 300 through the analog switch array 103.

[0049] The main control processor 101 generates valve control commands based on intracavity environmental data and sends these commands to the programmable logic controller (PLC) 104; it also sends valve status results to the baseboard management controller 400. The PLC 104 generates pulse width modulation (PWM) signals based on the valve control commands and sends these signals to the valve control board 300. The solenoid valve drive circuit 700 modulates the PWM signals to control the valve opening / closing state of the solenoid valve 500. The analog switch array 103 switches the connection status between the data sampling channel of the dedicated processor 102 and each solenoid valve drive circuit 700, enabling the dedicated processor 102 to collect the real-time valve status voltage of the solenoid valve 500 corresponding to each solenoid valve drive circuit 700. The dedicated processor 102 generates valve status results based on the real-time valve status voltage and sends these results to the main control processor 101. The real-time valve status voltage corresponds to the valve opening / closing state.

[0050] In one possible implementation, the main control processor 101 communicates with the sensor 200 via an IIC bus. The main control processor 101 also communicates with the programmable controller 104 via a UART communication protocol. Furthermore, the main control processor 101 communicates with a dedicated processor 102 via a CAN bus. Finally, the main control processor 101 communicates with the baseboard management controller 400 via an IIC bus. The solenoid valve 500 includes an inlet solenoid valve 500J and a drain solenoid valve 500P.

[0051] Furthermore, the switching process of the analog switch array 103 is controlled by a dedicated processor 102. Specifically, for example, the analog switch array 103 includes a first analog switch and a second analog switch, and the drain solenoid valve 500P includes a first discharge solenoid valve and a second discharge solenoid valve; the dedicated processor 102 controls the first analog switch to remain open and the second analog switch to remain closed, thereby acquiring the real-time valve status voltage of the first discharge solenoid valve corresponding to the solenoid valve drive circuit of the first analog switch. By switching the corresponding analog switches through periodic polling of the analog switch array, the number of analog-to-digital conversion pins required by the dedicated processor is reduced, lowering the hardware cost of the circuit; or, based on the valve failure probability or remaining service life of each solenoid valve, the polling switching order of each analog switch is dynamically adjusted, improving the timeliness of valve control and status detection.

[0052] The dedicated processor 102 generates the valve status result of the solenoid valve 500 by comparing the real-time valve status voltage with voltage range thresholds. These voltage range thresholds include voltage range thresholds for the valve open state, valve closed state, coil short-circuit state, coil burnout state, and mechanical jamming state. Further, the voltage range thresholds indicate the valve status within a preset voltage range; for example, the voltage range threshold for the valve open state is 1.5V~2.0V, the voltage range threshold for the coil short-circuit state is 0~0.5V, and the voltage range threshold for the mechanical jamming state is 0.8V~1.2V.

[0053] Specifically, the dedicated processor 102 samples the real-time state voltage of the solenoid valve 500 and compares it with a preset voltage range threshold. When the real-time state voltage is within the open state voltage range threshold, the solenoid valve 500 is determined to be in the open state, and the valve state result is open. When the real-time state voltage is within the coil short-circuit state voltage range threshold, the solenoid valve 500 is determined to have a coil short-circuit fault, and the valve state result is coil short-circuit fault. When the real-time state voltage is within the mechanical jamming state voltage range threshold, the solenoid valve 500 is determined to have a mechanical jamming fault, and the valve state result is mechanical jamming fault. The dedicated processor 102 then transmits the valve state result to the main control processor 101 via the CAN bus. By comparing voltage range thresholds, the dedicated processor 102 achieves accurate identification of multiple valve fault modes, solving the problem in related technologies that can only detect the open / closed state of the solenoid valve.

[0054] In this embodiment, a hierarchical architecture is used to separate the main control processor and the dedicated processor. The main control processor is used to acquire the intracavity environmental data collected by the sensor and generate valve control commands for the corresponding solenoid valve based on the intracavity environmental data. The dedicated processor is used to acquire the real-time state voltage of the valve and generate the valve state result based on the real-time state voltage of the valve. This realizes the valve state monitoring and fault diagnosis of the solenoid valve, avoids hardware resource competition and task conflicts, and solves the problem of lag in fault diagnosis of the solenoid valve.

[0063] Figure 6 A schematic diagram of the valve control and status detection circuit of the liquid cooling equipment provided in the embodiments of this application. Figure 6 ,like Figure 6 As shown, in Figure 1 Based on the embodiments, the control processing module 100 includes a main control processor 101, a programmable controller 104, and one or more analog-to-digital converters 105; the valve control board 300 includes multiple solenoid valve drive circuits 700.
