Description

Technical Field

[0001] The present invention relates to the technical field of data security, and in particular to a fuse temperature control method. Background Art

[0002] A fuse is a device that disconnects the circuit to be protected by triggering the melting of the fuse due to overcurrent heating. In various application fields, fuses are often used to protect circuits from damage due to overload or short circuit. In complex application environments and working conditions, fuses are often subjected to thermal stress. If the fuse is in a high temperature state for a long time, its service life will be shortened, and it may even be disconnected under the continuous impact of small current. Especially in the fields of energy storage and new energy vehicles, frequent starting and stopping, acceleration, and charging and discharging will test the fuse's ability to withstand thermal stress.

Figure 1 As shown, the control system includes: a control terminal and M intelligent fuses, where M is an integer greater than 2.

[0039] The control terminal may be a terminal device with transceiver and processing functions, or a chip or chip system that can be set in the terminal device. The terminal device may also be called user equipment (UE), access terminal equipment, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal equipment, mobile equipment, user terminal equipment, terminal equipment, wireless communication equipment, user agent or user device.

Or the terminal device may also be a customer-premises equipment (CPE).

[0040] The smart fuse may be a smart fuse that is connected to the control terminal in communication. The smart fuse is provided with a thermostat, which can collect the operating temperature of the smart fuse and feed it back to the control terminal. The thermostat is also provided with a heating component, which can increase the operating temperature of the smart fuse by heating.

[0041] Figure 2 This is a flow chart of a method provided by an embodiment of the present invention. The fuse temperature control method can be applied to the above-mentioned control terminal. The specific process is as follows:

[0042] S201, the control terminal obtains topological relationship information of M smart fuses.

[0043] The control terminal can obtain the topological relationship information of M smart fuses from the database or cloud center platform. For example, M smart fuses are configured in a certain power system, and the control terminal can send the system identifier of the power system to the database or cloud center platform, as well as the information indicating the topological relationship of the smart fuses to be obtained, and the database or cloud center platform can return the topological relationship information of the M smart fuses to the control terminal.

[0044] S202: The control terminal selects N discrete smart fuses from the M smart fuses according to the topological relationship information of the M smart fuses, where N is an integer greater than 1 and less than M.

[0045] Case 1:

[0046] The topological relationship information of the M smart fuses indicates the physical positions of the M smart fuses. That is, the topological relationship information includes the position coordinates of the M smart fuses. The position coordinates of each of the M smart fuses are obtained by mapping the actual physical position of the smart fuse. In other words, the position coordinates of the M smart fuses can roughly reflect the actual physical position distribution of the M smart fuses.

[0047] On this basis, the control terminal can select N smart fuses with discrete physical location distribution from the M smart fuses according to the physical locations of the M smart fuses.

[0048] For example, the control terminal may randomly select one smart fuse from the M smart fuses as the first smart fuse according to the physical positions of the M smart fuses, and the first smart fuse is located at the first physical position. The control terminal may select the smart fuse farthest from the first smart fuse (i.e., the distance between coordinates is the largest) from the M smart fuses as the second smart fuse according to the first smart fuse being located at the first physical position and the physical positions of the M smart fuses, and the second smart fuse is located at the second physical position. The control terminal may select the smart fuse farthest from the first smart fuse from the M smart fuses as the second smart fuse according to the first smart fuse being located at the first physical position and the physical positions of the M smart fuses, and the second smart fuse is located at the second physical position. According to the first smart fuse being located at the first physical position, the second smart fuse being located at the second physical position, and the physical positions of the M smart fuses, the control terminal selects the smart fuse farthest from the first smart fuse and the second smart fuse from the M smart fuses (i.e., the smart fuse with the largest sum of the distance between its own coordinates and the coordinates of the first smart fuse and the distance between its own coordinates and the coordinates of the second smart fuse) as the third smart fuse, and the second smart fuse is located at the third physical position. This is repeated by analogy until the smart fuse farthest from the first smart fuse, the second smart fuse, and even the N-1 smart fuse is selected from the M smart fuses as the Nth smart fuse, and a total of N smart fuses are selected. In this way, N smart fuses with relatively discrete position distribution can be selected.

[0049] Optionally, the value of N is determined according to the value of M, such as N=ceil(M / X), X=2, 3, 4, etc., ceil means rounding up, the larger the value of M is, the larger the value of X is, and " / " means division, that is, M divided by X. The same applies to similar expressions below and will not be repeated here.

[0050] Case 2:

[0051] The control terminal determines the physical positions of the M smart fuses according to the physical positions of the M smart fuses. On this basis, the control terminal can determine the circumscribed circle of the physical positions of the M smart fuses according to the physical positions of the M smart fuses.

[0052] The control terminal determines the circumscribed circle to be K concentric circles, where K is an integer greater than 2. The K concentric circles are concentric circles with equal spacing.

[0053] The control terminal determines whether there are smart fuses distributed in the first area between the Kth concentric circle and the K-1th concentric circle among the K concentric circles. If there are P1 smart fuses distributed in the first area, if P1 is an even number greater than 1, the control terminal randomly selects P1 / 2 smart fuses from the P1 smart fuses, and if P1 is an odd number greater than 1, the control terminal randomly selects P1 / 2+1 smart fuses from the P1 smart fuses. Afterwards, the control terminal does not select the area between the K-1th concentric circle and the K-2th concentric circle among the K concentric circles to ensure discreteness. The control terminal determines whether there are smart fuses distributed in the second area between the K-2nd concentric circle and the K-3rd concentric circle among the K concentric circles. In the case that P2 smart fuses are distributed in the second area, if P2 is an even number greater than 1, the control terminal randomly selects P2 / 2 smart fuses from the P2 smart fuses; if P2 is an odd number greater than 1, the control terminal randomly selects P2 / 2+1 smart fuses from the P2 smart fuses; and so on, until the control terminal determines that the xth area between the second concentric circle and the first concentric circle among the K concentric circles or the area within the first concentric circle Whether there are smart fuses distributed in the area included in the xth area or the first concentric circle, when there are no Px smart fuses distributed in the xth area or the area included in the first concentric circle, Px is an integer greater than 1, and the selection of the smart fuse ends. When there are Px smart fuses distributed in the xth area or the area included in the first concentric circle, if Px is an even number greater than 1, the control terminal randomly selects Px / 2 smart fuses from the Px smart fuses; if Px is an odd number greater than 1, the control terminal randomly selects Px / 2+1 smart fuses from the Px smart fuses, and the selection of the smart fuse ends.

[0054] In one example, Figure 3 As shown, K=3, 3 smart fuses are selected in the first area between the 4th concentric circle and the 3rd concentric circle, and 3 smart fuses are selected in the second area between the 2nd concentric circle and the 1st concentric circle, and a total of 6 smart fuses are selected.

[0055] Case 3:

[0056] The topological relationship information of the M smart fuses indicates the electrical connection topology of the M smart fuses, and the electrical connection topology represents the electrical connection relationship between the M smart fuses. On this basis, the control terminal selects N smart fuses located at key connection positions of the electrical connection topology from the M smart fuses according to the electrical connection topology of the M smart fuses.

[0057] For example, in order to reduce the impact of the fuse protection on the entire system, the control terminal can determine at least one branch containing at least two nodes from the electrical connection topology of M smart fuses, and any of the M smart fuses is used as a node in the electrical connection topology. The control terminal selects the smart fuse located at the second node of each branch in at least one branch, and a total of N smart fuses are selected. The position of the second node of each branch in at least one branch is the key connection position. In one example, Figure 4 As shown, a branch is counted from a fork, where a fork is a node connecting at least three other nodes, such as Figure 4 Branch 1 to branch 7 in the figure, a total of 8 smart fuses are selected.

[0058] For example, to ensure the safety of the system, the control terminal can select a smart fuse located in a star connection position in the electrical connection topology from the M smart fuses according to the electrical connection topology of the M smart fuses, and a total of N smart fuses are selected. The star connection position in the electrical connection topology is a key connection position of the electrical connection topology; the smart fuse in the star connection position is connected to at least three other smart fuses in the M smart fuses. In one example, Figure 5 As shown, a total of 4 smart fuses are selected.

[0059] S203, the control terminal controls the operating temperatures of the N smart fuses to a preset temperature range.

[0060] The upper limit temperature of the preset temperature range is lower than the fusing temperature of any smart fuse among the M smart fuses, and the lower limit temperature of the preset temperature range is higher than the operating temperature of the smart fuses other than the N smart fuses among the M smart fuses.

[0061] For example, the control terminal can determine the preset temperature range based on the operating temperature of each of the M smart fuses and the current load of the power system. The higher the current load, the closer the upper limit temperature of the preset temperature range is to the fusing temperature of any of the M smart fuses; the control terminal can control the operating temperatures of the N smart fuses to within the preset temperature range through their respective thermostats.

[0062] To summarize, the control terminal can obtain the topological relationship information of M smart fuses, and select a discrete part of the smart fuses, such as N smart fuses, from the M smart fuses based on the topological relationship information of the M smart fuses, so as to control the working temperature of the N smart fuses to a suitable preset temperature range, such as the upper limit temperature of the preset temperature range is lower than the melting temperature of any smart fuse among the M smart fuses, and the lower limit temperature of the preset temperature range is higher than the working temperature of the smart fuses other than the N smart fuses among the M smart fuses, so that both performance and cost overhead can be taken into account.

[0063] Combination of the above Figure 2 The method provided by the embodiment of the present invention is described in detail. A fuse temperature control device for executing the method provided by the embodiment of the present invention is described in detail below, the device includes a control terminal, and the device is configured as follows: the control terminal obtains topological relationship information of M smart fuses, M is an integer greater than 2; the control terminal selects discrete N smart fuses from the M smart fuses according to the topological relationship information of the M smart fuses, N is an integer greater than 1 and less than M; the control terminal controls the working temperature of the N smart fuses to a preset temperature range, the upper limit temperature of the preset temperature range is lower than the fusing temperature of any smart fuse among the M smart fuses, and the lower limit temperature of the preset temperature range is higher than the working temperature of the smart fuses other than the N smart fuses among the M smart fuses.

[0064] Optionally, the topological relationship information of M smart fuses indicates the respective physical positions of the M smart fuses; the control terminal selects N discrete smart fuses from the M smart fuses according to the topological relationship information of the M smart fuses, including: the control terminal selects N smart fuses with discrete physical position distribution from the M smart fuses according to the respective physical positions of the M smart fuses.
