[0027] To solve the electromagnetic problems of vehicle systems or components, it is necessary to collect data on the network signals, voltage signals, and current signals of vehicle systems or components in a strong electromagnetic interference environment. To avoid irreversible destructive damage to data acquisition devices (such as upper computers, spectrum analyzers, and oscilloscopes, etc.) caused by the strong electromagnetic environment, an optical-electric converter is usually used to perform optical-electric conversion on the acquired signals and then transfer them to the control room for monitoring. However, this method has the following problems:
[0028] 1. Affected by parameters such as the conversion rate of the optical-electric converter, some of the acquired data transmitted to the control room may be distorted, resulting in inaccurate acquired data, and further leading to inaccurate test results.
[0029] 2. The monitoring device is placed in the control room and cannot send control instructions to the device under test. For example, it is impossible to send a trigger condition to the device under test through the upper computer, resulting in low test efficiency.
[0030] Based on the above problems, an embodiment of the present application provides an electromagnetic shielding room, which includes a shielding shell made of electromagnetic shielding material and a shielding door made of electromagnetic shielding material. The shielding shell and the shielding door form a closed space, and a grounding structure is provided on the shielding shell, and the shielding shell is grounded through the grounding structure. Since both the shielding shell and the shielding door are made of shielding material and the shielding shell is grounded through the grounding structure, the closed space formed by the shielding shell and the shielding door is not affected by electromagnetic interference. When the test personnel and monitoring equipment are located in the closed space, they are not affected by the electromagnetic interference in the electromagnetic laboratory, achieving the effect of protecting the test personnel and monitoring equipment. A wiring harness through hole for the monitoring wiring harness to pass through is provided on the shielding shell. When testing the device under test, one end of the monitoring wiring harness is connected to the device under test, and the other end of the monitoring wiring harness passes through the wiring harness through hole and is connected to the monitoring equipment in the closed space. At this time, the monitoring equipment can collect the real signal of the device under test through the monitoring wiring harness, avoiding the problem that the test result is inaccurate due to the distortion of the collected signal. At the same time, the monitoring equipment can also send control instructions to the device under test through the monitoring wiring harness to complete various test items of the device under test, improving the test efficiency.
[0031] In order to illustrate the technical solution described in the present application, the following will be described through specific embodiments.
[0032] See Figure 1 and Figure 2 As shown, the electromagnetic shielding room 10 includes a shielding shell 100 made of electromagnetic shielding material and a shielding door 200 made of electromagnetic shielding material. The shielding shell 100 and the shielding door 200 form a closed space 500 for people to enter. The closed space 500 is used to place the monitoring equipment 800. A grounding structure 300 is provided on the shielding shell 100, and the shielding shell 100 is grounded through the grounding structure 300. A wiring harness through hole 400 for the monitoring wiring harness 700 to pass through is also provided on the shielding shell 100.
[0033] Specifically, both the shielding shell 100 and the shielding door 200 are made of shielding material, and a grounding structure 300 is provided on the shielding shell 100. The shielding shell 100 is grounded through the grounding structure 300, enabling the shielding shell 100 and the shielding door 200 to shield the electromagnetic signals in the electromagnetic laboratory 20. The electromagnetic signals cannot enter the closed space 500 formed by the shielding shell 100 and the shielding door 200. When the test personnel and the monitoring equipment 800 are located in the closed space 500, the test personnel and the monitoring equipment 800 are not affected by electromagnetic interference, achieving the effect of protecting the test personnel and the monitoring equipment 800.
[0034] Meanwhile, a wire harness through-hole 400 for the monitoring wire harness 700 to pass through is provided on the shielding case 100. When testing the device under test 600, one end of the monitoring wire harness 700 is connected to the device under test 600, and the other end of the monitoring wire harness 700 passes through the wire harness through-hole 400 and is connected to the monitoring device 800 in the enclosed space 500. At this time, the monitoring device 800 can collect the real signals of the device under test 600 through the monitoring wire harness 700, avoiding the problem that the test results are inaccurate due to the distortion of the collected signals. Meanwhile, the monitoring device 800 can also send control instructions to the device under test 600 through the monitoring wire harness 700. The device under test 600 completes corresponding responses according to the control instructions, and the monitoring device 800 collects the response signals of the device under test 600 through the monitoring wire harness 700, thereby completing various test items of the device under test 600 and improving the test efficiency.
[0035] It should be noted that the designers can set the electromagnetic shielding room 10 at a suitable position in the electromagnetic test room 20 according to the actual situation. When determining the position of the electromagnetic shielding room 10, it is necessary to ensure that the electromagnetic shielding room 10 does not affect the electromagnetic field around the device under test 600. The specific position of the electromagnetic shielding room 10 is not limited herein.
[0036] In some embodiments, the grounding structure 300 includes a plurality of grounding fasteners. The shielding case 100 is grounded and fixed on the ground of the electromagnetic test room 20 through the grounding fasteners.
[0037] Specifically, the plurality of grounding fasteners are distributed at the bottom of the shielding case 100, and the shielding case 100 is grounded and fixed on the ground of the electromagnetic test room 20 through the grounding fasteners.
[0038] Exemplarily, the grounding fastener is selected as a grounding bolt. A grounding through-hole adapted to the grounding bolt is provided at the bottom of the shielding case 100, and the grounding bolt is passed through the grounding through-hole and fixed on the ground of the electromagnetic test room 20, thereby realizing grounding and fixing the shielding case 100 on the ground of the electromagnetic test room 20 through the grounding fasteners.
[0039] It should be noted that in order to ground the shielding case 100, the grounding fastener should be made of a material with good electrical conductivity. For example, a grounding fastener made of a metal material is selected.
[0040] In some embodiments, such as Figure 3As shown, the electromagnetic shielding room 10 further includes multiple sets of shielding components, which are respectively adapted to monitoring wire harnesses 700 with various different wire diameters. The shielding component includes a first shielding member 103 and a second shielding member 104. The first shielding member 103 is detachably connected to the shielding shell 100, and the second shielding member 104 is detachably connected to the shielding shell 100. When the first shielding member 103 and the second shielding member 104 are installed on the shielding shell 100, the first shielding member 103 and the second shielding member 104 fix the monitoring wire harness 700 and completely shield the wire harness through-hole 400.
[0041] Specifically, when different DUTs 600 are being tested, monitoring wire harnesses 700 with different wire diameters may be required. For example, sometimes a monitoring wire harness 700 with a relatively thin wire diameter is needed, and sometimes a monitoring wire harness 700 with a relatively thick wire diameter is needed. To accommodate different wire harnesses, the aperture of the wire harness through-hole 400 can be appropriately increased. For example, the aperture of the wire harness through-hole 400 is larger than the wire diameter of the largest wire diameter monitoring wire harness 700, so that all monitoring wire harnesses 700 can pass through the wire harness through-hole 400.
[0042] Based on the monitoring wire harnesses 700 with various different wire diameters, multiple sets of shielding components are provided, and the multiple sets of shielding components are respectively adapted to the monitoring wire harnesses 700 with various different wire diameters. Each set of shielding components includes a first shielding member 103 and a second shielding member 104, and both the first shielding member 103 and the second shielding member 104 are provided with grooves. When the first shielding member 103 and the second shielding member 104 move on the shielding shell 100 until they come into contact, the grooves on the first shielding member 103 and the grooves on the second shielding member 104 form a limiting through-hole, and the cross-section of the limiting through-hole is the same as the size and shape of the cross-section of the corresponding monitoring wire harness 700. Thus, when the first shielding member 103 and the second shielding member 104 are in contact, the first shielding member 103 and the second shielding member 104 can fix the monitoring wire harness 700, ensuring that there is no gap between the monitoring wire harness 700, the first shielding member 103, and the second shielding member 104. At the same time, the first shielding member 103 and the second shielding member 104 completely shield the wire harness through-hole 400, ensuring that the electromagnetic signals in the electromagnetic test chamber 20 do not enter the enclosed space 500 through the wire harness through-hole 400.
[0043] When actually testing the device under test 600, first determine the monitoring wire harness 700 to be used, and then determine the shielding component adapted to the monitoring wire harness 700. After the shielding component is determined, connect one end of the monitoring wire harness 700 to the device under test 600, pass the other end of the monitoring wire harness 700 through the wire harness through-hole 400 and connect it to the monitoring device 800 in the sealed space 500, and then install the first shielding member 103 and the second shielding member 104 on the shielding case 100. When the first shielding member 103 and the second shielding member 104 are in contact, the monitoring wire harness 700 is restricted within the limiting through-hole formed by the first shielding member 103 and the second shielding member 104, thereby realizing the position fixation of the monitoring wire harness 700. At the same time, the first shielding member 103 and the second shielding member 104 completely shield the wire harness through-hole 400, ensuring that the electromagnetic signals in the electromagnetic test chamber 20 do not enter the sealed space 500 through the wire harness through-hole 400.
[0044] Exemplarily, as Figure 3 shown, the shielding case 100 is provided with a first guiding groove 101 and a second guiding groove 102. The first guiding groove 101 and the second guiding groove 102 are located on the same side of the shielding case 100 and are respectively arranged on both sides of the wire harness through-hole 400. The first shielding member 103 can move within the first guiding groove 101, and the second shielding member 104 can move within the second guiding groove 102. When the first shielding member 103 and the second shielding member 104 are in contact, the first shielding member 103 and the second shielding member 104 can fix the monitoring wire harness 700. At the same time, the first shielding member 103 and the second shielding member 104 completely shield the wire harness through-hole 400, ensuring that the electromagnetic signals in the electromagnetic test chamber 20 do not enter the sealed space 500 through the wire harness through-hole 400.
[0045] In addition to using the above-described methods, the connection method of the first shielding member to the shielding case 100 and the connection method of the second shielding member to the shielding case 100 can also use other methods. For example, a first guiding boss and a second guiding boss are provided on the shielding case 100. The first guiding boss and the second guiding boss are located on the same side of the shielding case 100 and are respectively arranged on both sides of the wire harness through-hole 400. A guiding groove adapted to the first guiding boss is provided on the first shielding member, and a guiding groove adapted to the second guiding boss is provided on the second shielding member.
[0046] The guiding groove on the first shielding member is sleeved on the first guiding boss and can slide on the first guiding boss.
[0047] The guiding groove on the second shielding member is sleeved on the second guiding boss and can slide on the second guiding boss. When the first shielding member and the second shielding member come into contact, the first shielding member and the second shielding member can fix the monitoring wire harness 700, and at the same time, the first shielding member and the second shielding member completely shield the wire harness through-hole 400, ensuring that the electromagnetic signals in the electromagnetic test chamber 20 will not enter the enclosed space 500 through the wire harness through-hole 400. The present application does not limit the connection manner between the first shielding member and the shielding case 100 and the connection manner between the second shielding member and the shielding case 100.
[0048] In some embodiments, the shielding assembly further includes a first fastener and a second fastener. The first shielding member is fixed to the shielding case 100 through the first fastener, and the second shielding member is fixed to the shielding case 100 through the second fastener.
[0049] Specifically, when the first shielding member and the second shielding member come into contact, the first shielding member is fixed to the shielding case 100 through the first fastener, and the second shielding member is fixed to the shielding case 100 through the second fastener, so that the first shielding member and the second shielding member fix the monitoring wire harness 700.
[0050] Exemplarily, the first fastener is selected as a first fastening bolt, and the second fastener is selected as a second fastening bolt. The first shielding member is provided with a first fastening screw hole adapted to the first fastening bolt, and the second shielding member is provided with a second fastening screw hole adapted to the second fastening bolt. When the first shielding member and the second shielding member move on the shielding case 100 to come into contact, align the first fastening bolt with the first fastening screw hole and tighten it, so that the end of the first fastening bolt abuts against the shielding case 100 to fix the first shielding member on the shielding case 100; at the same time, align the second fastening bolt with the second fastening screw hole and tighten it, so that the end of the second fastening bolt abuts against the shielding case 100 to fix the second shielding member on the shielding case 100. Thus, the first shielding member can be fixed to the shielding case 100 through the first fastener, and the second shielding member can be fixed to the shielding case 100 through the second fastener.
[0051] The above only describes a method of fixing the first shielding member to the shielding case 100 through the first fastener and fixing the second shielding member to the shielding case 100 through the second fastener. Designers can also design other methods according to actual situations. The present application does not limit the specific structures of the first fastener and the second fastener and the fastening manners of the first fastener and the second fastener.
[0052] In an embodiment of the present application, both the first shielding member and the second shielding member are made of electromagnetic shielding materials.
[0053] Specifically, both the first shielding member and the second shielding member are made of electromagnetic shielding materials, which can prevent the electromagnetic signals in the electromagnetic test chamber 20 from entering the enclosed space 500 through the wire harness through-hole 400, improving the electromagnetic shielding effect of the electromagnetic shielding chamber 10.
[0054] It should be noted that the electromagnetic shielding materials referred to in this application can be selected from existing electromagnetic shielding materials. For example, galvanized steel plates, stainless steel, carbon fiber composite plates or other electromagnetic shielding materials. Designers can select the specific type of electromagnetic shielding materials according to the actual situation, and the specific materials of the electromagnetic shielding materials are not limited here.
[0055] In some embodiments, an operating table is provided in the enclosed space 500, and the operating table is used to place the monitoring device 800.
[0056] Specifically, by providing an operating table in the enclosed space 500, the monitoring device 800 can be placed on the operating table, which is convenient for the operation of the test personnel and helps to improve the test efficiency.
[0057] In some embodiments, a plurality of ventilation holes are provided on the shielding shell 100. Designing the ventilation holes can allow the air in the enclosed space 500 to circulate with the outside, avoiding the feeling of stuffiness for the test personnel and improving the comfort of the test personnel.
[0058] It should be noted that in order to prevent the electromagnetic signals in the electromagnetic test chamber 20 from entering the enclosed space 500 through the ventilation holes, the aperture of the ventilation holes needs to be set as small as possible. The aperture of the ventilation holes can be set to the millimeter level. For example, the aperture of the ventilation holes can be set to 2 millimeters - 5 millimeters.
[0059] In some embodiments, the electromagnetic shielding chamber 10 further includes an electromagnetic shielding net, and the electromagnetic shielding net is provided on the shielding shell 100 and covers all the ventilation holes.
[0060] Specifically, the electromagnetic shielding net has an electromagnetic shielding effect. By providing the electromagnetic shielding net on the shielding shell 100 and covering all the ventilation holes, it can prevent the electromagnetic signals in the electromagnetic test chamber 20 from entering the enclosed space 500, improving the shielding effect of the electromagnetic shielding chamber 10.
[0061] Exemplarily, the electromagnetic shielding net can be made of copper, aluminum or other composite materials.
[0062] The present application also provides an electromagnetic monitoring system, which includes a monitoring device and the above-mentioned electromagnetic shielding room, and the monitoring device is placed in the enclosed space of the electromagnetic shielding room. The electromagnetic shielding room includes a shielding shell made of electromagnetic shielding material and a shielding door made of electromagnetic shielding material. The shielding shell and the shielding door form an enclosed space, and a grounding structure is provided on the shielding shell. Since both the shielding shell and the shielding door are made of shielding material and the grounding structure is provided on the shielding shell, the enclosed space formed by the shielding shell and the shielding door is not affected by electromagnetic interference. When the test personnel and the monitoring device are located in the enclosed space, they are not affected by the electromagnetic interference in the electromagnetic laboratory, achieving the effect of protecting the test personnel and the monitoring device. A wire harness through-hole for the monitoring wire harness to pass through is provided on the shielding shell. When testing the device under test, one end of the monitoring wire harness is connected to the device under test, and the other end of the monitoring wire harness passes through the wire harness through-hole and is connected to the monitoring device in the enclosed space. At this time, the monitoring device can collect the real signals of the device under test through the monitoring wire harness, avoiding the problem that the test results are inaccurate due to the distortion of the collected signals. At the same time, the monitoring device can also send control instructions to the device under test through the monitoring wire harness to complete various test items of the device under test, improving the test efficiency.
[0063] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
