Description

Technical Field

[0001] This invention relates to a pre-heating intelligent programmable switch. Background Technology

[0002] As communication data grows, the integration and throughput of switching chips (such as ASICs or NPUs) inside PBXs are constantly improving. When the switch handles massive concurrent services, the instantaneous power consumption of these switching chips will increase rapidly with the increase in traffic load, generating a large amount of heat.

[0003] Currently, existing PBX (Private Branch Exchange) cooling systems generally rely on temperature sensors deployed around the motherboard PCB or the casing of the switching chip to monitor temperature signals and adjust the speed of the cooling fan accordingly. However, due to the delay in heat conduction between the chip package, the thermal medium, and the heat dissipation components, the cooling system's response adjustment exhibits a significant lag. When the switch is dealing with sudden signaling addressing or high-bandwidth data pulses, the temperature rise rate of the core area inside the switching chip is much faster than the sensor's sensing speed. This passive "heating up first, then cooling down" working mode causes the switching chip to frequently experience instantaneous thermal shocks. This not only accelerates the fatigue aging of semiconductor components and packaging materials but also easily triggers automatic frequency reduction protection, leading to packet processing delays or even packet loss.

[0004] To compensate for this heat dissipation delay, simply keeping the cooling system's fans at high speeds will not only reduce the overall energy efficiency ratio of the device and shorten the lifespan of the cooling system, but also generate significant noise. Furthermore, continuous high-speed airflow will accelerate dust accumulation inside the chassis, thereby reducing long-term cooling performance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pre-heating intelligent program-controlled exchange that proactively adjusts heat dissipation power by monitoring the changing trends of service load data in real time.

[0006] The present invention provides a pre-heat-dissipating intelligent program-controlled exchange, comprising: Switching chips are used to process business data; Traffic monitoring unit is used to acquire business load data in real time; The heat dissipation component has a heat exchange relationship with the switching chip, and the output power of the heat dissipation component is controllable and adjustable; The heat dissipation control unit is connected to the flow monitoring unit and the heat dissipation component respectively, and adjusts the output power of the heat dissipation component according to the changing trend of the business load data.

[0007] The pre-heat-dissipating intelligent program-controlled exchange also includes: A temperature sensor, connected to the heat dissipation control unit, is located around the switching chip to acquire the temperature signal of the switching chip in real time. The heat dissipation control unit is used to determine the basic output power based on the changing trend of the service load data, and to compensate the basic output power based on the temperature signal to obtain the target output power of the heat dissipation component.

[0008] Furthermore, when the heat dissipation control unit detects that the service load data shows a downward trend, it maintains the current output power; when the maintenance time reaches a preset time and the temperature signal is lower than a preset temperature threshold, it gradually reduces the output power of the heat dissipation component.

[0009] Furthermore, the heat dissipation control unit calculates the growth slope of the service load data within a preset period. When the growth slope is greater than a preset slope threshold, the output power of the heat dissipation component is adjusted accordingly based on the magnitude of the growth slope.

[0010] Furthermore, the service load data includes at least one of the following: port packet forwarding rate, bit rate, depth of the internal buffer queue of the switching chip, and packet enqueue frequency.

[0011] The beneficial effects of this invention are as follows: This invention uses the changing trend of service load data as a pre-trigger condition for heat dissipation adjustment, breaking the traditional passive heat dissipation mode that relies solely on temperature feedback. When the switch faces a sudden surge in traffic, the system can proactively pre-cool the chip by adjusting the output power of the heat dissipation components before the chip heats up, thus avoiding the frequency reduction protection or data packet loss problems caused by the switching chip being subjected to instantaneous thermal shock. This significantly improves the data processing performance and long-term operational stability of the equipment in high-concurrency network environments. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the functional modules of an embodiment of the present invention; Figure 2 This is a flowchart illustrating an embodiment of the present invention. Detailed Implementation

[0013] This invention provides a pre-heat-dissipating intelligent program-controlled exchange, such as... Figure 1 As shown, it includes: a switching chip, a flow monitoring unit, a temperature sensor, a heat dissipation control unit, and a heat dissipation component.

[0014] Among them, the switching chip (such as ASIC chip or NPU network processor) is the heat source when processing massive business data. The heat dissipation component is placed above or around the switching chip. The heat dissipation component consists of components such as cooling fan and heat conductor. There is a heat exchange relationship between the heat dissipation component and the switching chip. The power of the heat dissipation component is adjustable.

[0015] The traffic monitoring unit is responsible for capturing the service load data of the underlying switching chip in real time.

[0016] Temperature sensors are placed around the switching chip to obtain temperature signals generated by the heat generated by the switching chip.

[0017] The heat dissipation control unit, as the core hub of the entire system, establishes signal connections with the flow monitoring unit, temperature sensor and heat dissipation components to achieve comprehensive control.

[0018] like Figure 2 As shown, during system operation, the heat dissipation control unit acquires service load data from the traffic monitoring unit and temperature signals from the temperature sensor in real time. The service load data includes one or more combinations of port packet forwarding rate, bit rate, depth of the internal buffer queue of the switching chip, and packet enqueue frequency. Compared with simply monitoring the macro rate of the port, monitoring the queue depth or enqueue frequency at the underlying level can more sensitively capture sudden traffic in the network, thereby gaining valuable time difference for early initiation of heat dissipation.

[0019] After acquiring the data, the system calculates the growth slope of the business load data within a preset period in real time and determines whether the growth slope is greater than the preset slope threshold. When the network faces a sudden high concurrency impact, the traffic surge will cause the growth slope to increase significantly. When it is determined that the growth slope is greater than the preset threshold, the heat dissipation control unit increases the output power of the heat dissipation component according to the specific magnitude of the growth slope. The larger the growth slope, the higher the output power of the heat dissipation component, and vice versa.

[0020] This preheating method can predict the temperature rise of the switching chip in advance and increase the output power of the heat dissipation components in advance. It overcomes the lag defect of traditional heat dissipation methods and can avoid problems such as equipment frequency reduction or data packet processing delay caused by thermal shock.

[0021] On the other hand, if the current growth rate does not exceed the threshold, the system determines whether the business load data shows a downward trend. When the high traffic volume recedes and the load drops sharply, traditional heat dissipation methods often immediately reduce the fan speed. However, this can easily cause the residual heat accumulated in the core of the switching chip to not dissipate in time, leading to a temperature rebound. To solve this problem, in this invention, when a load decrease is detected, the system first maintains the current output power and starts timing monitoring. Only when the system simultaneously meets the requirement of maintaining the output power for a preset duration and the current temperature signal is lower than the set preset temperature threshold, is the system allowed to gradually reduce the output power of the heat dissipation component. This heat dissipation method can prevent the problem of residual heat from the switching chip not being dissipated in time, avoid frequent changes in the output power of the heat dissipation component, effectively extend the service life of the heat dissipation component, and reduce the noise of the heat dissipation component during operation.

[0022] If the current workload does not experience a sharp increase or a significant decrease (i.e., it is operating smoothly or changing very slowly), the system automatically switches to a normalized adjustment mode. In this mode, the thermal control unit primarily determines the base output power based on the workload's changing trend, and then uses the actual measured temperature signal as feedback to fine-tune and compensate for this base power. For example, if the ambient temperature rises, causing the chip's measured temperature to be higher than expected, the system will add a certain amount of compensation speed to the base speed. This adjustment mode not only ensures the system's agility in responding to traffic flow but also takes into account precise temperature control and energy efficiency under normal conditions.

[0023] The above embodiments are merely one preferred embodiment of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
