Wherever possible, the same reference numerals will be used in all drawings to denote the same or similar parts. Furthermore, although the terminology used in this invention is selected from commonly known and used terminology, some terms mentioned in this specification may have been chosen by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of the description herein. Moreover, the invention should be understood not only by the actual terminology used, but also by the meaning implied by each term. Also, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0077] See Figures 1-6f This utility model provides a variable configuration test device for semi-physical simulation test of aero-engine control system. The test device includes a bus signal decomposition component 100, a magnetic control switching component 200, and a two-dimensional matrix mapping controller 300.

[0078] The bus signal decomposition component 100 includes a bus 110 and at least two sets of electrical connectors 120, the electrical connectors 120 being electrically connected to the bus 110, and the bus 110 being decomposed into at least two sets of input and output signal lines 111.

[0079] The magnetically controlled switching component 200 includes multiple magnetic switches 210, forming a matrix of magnetic switches 210. The magnetically controlled switching component 200 is electrically connected to each group of input / output signal lines 111.

[0080] The two-dimensional matrix mapping controller 300 stores a two-dimensional matrix table and is electrically connected to multiple magnetic switches 210. The controller controls the magnetic switches 210 to turn off according to the two-dimensional matrix table.

[0081] Figure 2b , Figure 6a , Figure 6c , Figure 6e An example of a two-dimensional matrix table is shown, in which 0 represents that the magnetic switch 210 of the corresponding line is open, and 1 represents that the magnetic switch 210 of the corresponding line is connected.

[0082] This utility model relates to a semi-physical simulation test device for variable configuration aero-engine control systems. It utilizes a magnetically controlled switching component 200 and a two-dimensional matrix mapping controller 300 to test aero-engine controllers with variable configurations. A switching matrix between input and output signals is established. The control software queries the corresponding two-dimensional matrix table based on the configuration information and controls the power signal on / off via a magnetic switch 210, thereby switching the cable box to the corresponding configuration. Through flexible adaptation, this device solves the problem of extensive cable modifications required due to configuration changes in aero-engine controllers.

[0083] See Figure 2a As a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the bus 110 includes a controller-side bus 114 and a test bench-side bus 115, two sets of electrical connectors 120 are controller-side electrical connector 121 and test bench-side electrical connector 122 respectively, and two sets of input / output signal lines 111 are controller-side input / output signal line 112 and test bench-side input / output signal line 113 respectively;

[0084] The controller-side electrical connector 121 is electrically connected to the controller-side bus 114, and the controller-side bus 114 is decomposed into controller-side input / output signal lines 112; the test bench-side electrical connector 122 is electrically connected to the test bench-side bus 115, and the test bench-side bus 115 is decomposed into test bench-side input / output signal lines 113.

[0085] Preferably, the controller-side electrical connector 121 can be an aviation plug or other type of electrical connector 120, used to connect the controller's input / output interface; the controller-side input / output signal line 112 transmits the controller-side signals decomposed through the bus 110. The test bench-side electrical connector 122 can be an aviation plug or other type of electrical connector 120, used to connect the test bench's simulated or real signal interface; the test bench-side input / output signal line 113 transmits the test bench-side signals decomposed through the bus 110.

[0086] In a preferred embodiment of the variable configuration test device for the semi-physical simulation test of the aero-engine control system of this utility model, the electrical connector 120 is an aviation plug.

[0087] As a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the two-dimensional matrix table is formed by mapping the signal interconnection relationship between the controller and the test bench.

[0088] As a preferred embodiment of the variable configuration test device for the semi-physical simulation test of the aero-engine control system of this utility model, the two-dimensional matrix mapping controller 300 controls the magnetic switch 210 to turn off according to the two-dimensional matrix table, and connects the corresponding line of the input / output signal line 112 at the controller end with the corresponding line of the input / output signal line 113 at the test bench end.

[0089] It should be noted that the two-dimensional matrix mapping controller 300 stores two-dimensional matrix tables corresponding to different configuration controllers. By selecting different two-dimensional matrix tables, the magnetic switch 210 matrix can be switched to the corresponding configuration state.

[0090] exist Figure 2a In the embodiment, the corresponding two-dimensional matrix table of the two-dimensional matrix mapping controller 300 is as follows: Figure 2b As shown.

[0091] Figures 6a-6f This is an example of a three-channel signal switching scheme. Figure 6a The input / output lines corresponding to the two-dimensional matrix table are as follows: Figure 6b As shown, Figure 6c The input / output lines corresponding to the two-dimensional matrix table are as follows: Figure 6d As shown, Figure 6e The input / output lines corresponding to the two-dimensional matrix table are as follows: Figure 6f As shown.

[0092] See Figures 1-6fIn a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the number of controller-end input / output signal lines 112 and test bench-end input / output signal lines 113 are equal; the corresponding line of each controller-end input / output signal line 112 is connected to only one corresponding line of the test bench-end input / output signal line 113.

[0093] The above settings ensure that the input / output signal lines 112 on the controller side correspond one-to-one with the input / output signal lines 113 on the test bench side, facilitating switching.

[0094] See Figures 1-3 In a preferred embodiment of the variable configuration test device for the semi-physical simulation test of the aero-engine control system of this utility model, the number of input / output signal lines 112 at the controller end and input / output signal lines 113 at the test bench end are both M. Each input / output signal line 113 at the test bench end has M control lines leading out to connect to each input / output signal line 112 at the controller end. Each control line is equipped with a magnetic switch 210, and the number of magnetic switches 210 is M*M; where M is a natural number and M≥2.

[0095] Preferably, there are N controller-side electrical connectors 121 and N test bench-side electrical connectors 122. All N controller-side electrical connectors 121 are connected to the controller-side bus 114, and all N test bench-side electrical connectors 122 are connected to the test bench-side bus 115. Wherein, N is a natural number and N≥2.

[0096] Specifically, the controller-side electrical connector 121 includes electrical connectors 120 of different specifications and quantities, including a first controller-side electrical connector 1211, a second controller-side electrical connector 1212, ..., an Nth controller-side electrical connector 121N, and the specific number of controller-side electrical connectors 121 varies according to the controller's interface.

[0097] The first controller-side electrical connector 1211 to the Nth controller-side electrical connector 121N are all connected to the controller-side bus 114.

[0098] The controller input / output signal line 112 is derived from the controller bus 114. The controller input / output signal line 112 is used to transmit the signals derived from the controller bus 114. The controller input / output signal line 112 includes a first controller input / output signal line 1121, a second controller input / output signal line 1122, ..., an Mth controller input / output signal line 112M. The type and number of controller input / output signal lines 112 are consistent with those defined in the controller electrical connector 121.

[0099] The test bench end electrical connector 122 includes connectors of different specifications and quantities, including the first test bench end electrical connector 1221, the second test bench end electrical connector 1222, ..., the Nth test bench end electrical connector 122N. The specific number of test bench end electrical connectors 122 varies according to the interface of the test bench.

[0100] The first test bench terminal connector 1221 to the Nth test bench terminal connector 122N are all connected to the test bench terminal bus 115.

[0101] The test bench input / output signal line 113 is derived from the test bench bus 115. The test bench input / output signal line 113 is used to transmit the signals derived from the test bench bus 115. The test bench input / output signal line 113 includes the first test bench input / output signal line 1131, the second test bench input / output signal line 1132, ..., the Mth test bench input / output signal line 113M. The type and number of the test bench input / output signal lines 113 are consistent with those defined in the test bench electrical connector 122.

[0102] The controller-side input / output signal line 112 is interconnected with the test bench-side input / output signal line 113 via a magnetic switch matrix 210. By switching the magnetic switch matrix 210, any signal in the controller-side input / output signal line 112 can be connected to any signal in the test bench-side input / output signal line 113.

[0103] See Figure 2a , Figure 4a and Figure 4b As a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the test device includes a load circuit 400 and a control circuit 500. The load circuit 400 is a circuit formed by connecting two sets of electrical connectors 120. The control circuit 500 controls the on / off of the load circuit 400. A two-dimensional matrix mapping controller 300 is set in the control circuit 500.

[0104] The magnetic switch 210 includes an actuation component 211 and a control component 212. The actuation component 211 is disposed in the load circuit 400, and the control component 212 is disposed in the control circuit 500. The actuation component 211 is triggered to operate by the magnetic field generated by the current in the control circuit 500, so as to connect or disconnect the load circuit 400.

[0105] See Figure 4a and Figure 4bAs a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the control component 212 includes a magnetic field enhancement component 213 and a coil 214. The coil 214 is wound around the magnetic field enhancement component 213, and the two ends of the coil 214 are connected to the control loop 500.

[0106] The actuation assembly 211 includes a magnetic rotating component 215, a fixed contact 216, a moving contact 217, and an elastic element 218. One end of the magnetic rotating component 215 is rotatably connected to the input terminal of the load circuit 400, and the other end of the magnetic rotating component 215 is connected to the moving contact 217. The fixed contact 216 is connected to the output terminal of the load circuit 400, and the elastic element is connected between the fixed contact 216 and the moving contact 217.

[0107] The elastic element 218 prevents the fixed contact 216 and the moving contact 217 from contacting each other through its elastic force. When the control component 212 generates a magnetic field, the magnetic force drives the magnetic rotating component 215 to rotate against the elastic force of the elastic element 218, so that the fixed contact 216 and the moving contact 217 come into contact.

[0108] As a preferred embodiment of the variable configuration test device for semi-physical simulation test of the aero-engine control system of this utility model, the magnetic field enhancement component 213 is an iron core and the elastic element 218 is a spring.

[0109] like Figure 4a and Figure 4b As shown, the actuation component 211 of the magnetic switch 210 is connected between the input port In and the output port Out of the load circuit 400, and the control component 212 of the magnetic switch 210 is connected between the first terminal X and the second terminal Y of the control circuit 500.

[0110] It should be noted that the magnetic switch 210 is in the off state by default, that is, no voltage is applied between the first terminal X and the second terminal Y. The magnetic rotating part 215 is opened by the action of the spring, which is the elastic element 218. The fixed contact 216 and the moving contact 217 are not in contact. The spring is provided with insulating material. Therefore, in this state, the input port In and the output port Out do not form a closed loop. The operation of the magnetic switch 210 when closed is as follows: The first terminal X and the second terminal Y are connected to the positive and negative voltage terminals output by the two-dimensional matrix mapping controller 300, respectively. Current flows from the first terminal X to the second terminal Y, thereby transmitting a weak control signal output by the two-dimensional matrix mapping controller 300 in the control circuit 500. A coil 214 is provided between the first terminal X and the second terminal Y, and the coil 214 is wound around the magnetic field enhancing component 213. When current flows from the first terminal X to the second terminal Y, a magnetic field B is generated. Under the action of the magnetic field B, the magnetic rotating component 215 tends to move in the closing direction. When the magnetic force is greater than the spring force, the magnetic rotating component 215 begins to rotate in the closing direction. When the fixed contact 216 and the moving contact 217 contact, the sum of the spring force and the contact force balances the magnetic force. The fixed contact 216 and the moving contact 217 are connected to the input and output ports, respectively, thereby connecting the input port In and the output port Out.

[0111] like Figure 5 As shown, a specific embodiment of the variable configuration test device for semi-physical simulation of aero-engine control system of this utility model is as follows:

[0112] Taking the example of three input / output signal lines 111 connected to the controller and three input / output signal lines 111 connected to the test bench, the signals of the first input port In1, the second input port In2 and the third input port In3 all come from the output / output signal lines of the controller, and the signals of the first output port Out1, the second output port Out2 and the third output port Out3 all come from the input / output signal lines 111 of the test bench.

[0113] The switching matrix consists of three parts: the first magnetic control switching component 2001, the second magnetic control switching component 2002, and the third magnetic control switching component 2003.

[0114] The first magnetic switching component 2001 includes a first magnetic switch 2101, a second magnetic switch 2102, and a third magnetic switch 2103.

[0115] The first magnetic switch 2101 includes a magnetic rotating component 215. The magnetic rotating component 215 has a voltage withstand capability that can withstand the voltage requirements of the output signal line of the controller, and can be a high-power signal or a low-voltage signal. The magnetic rotating component 215 is supported by a spring to maintain the magnetic switch 210 in the open state.

[0116] The output port of the first magnetic switch 2101 is the first output port Out1. When the first magnetic switch 2101 is turned on, the controller signal is connected to the test bench through the first output port Out1.

[0117] The first magnetic switch 2101 is controlled by an iron core and a coil 214 wound around the iron core.

[0118] 214 is connected to the output of the two-dimensional matrix mapping controller 300. The input of coil 214 is a weak electrical signal. When coil 214 is energized, it can generate an attractive force sufficient to overcome the spring force, thereby causing the magnetic rotating component 215 of the first magnetic switch 2101 to close.

[0119] The terminals of the coil 214 of the first magnetic switch 2101 are connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300. The two-dimensional matrix mapping controller 300 can calculate the corresponding configuration switching matrix table, i.e., the two-dimensional matrix table, through the configuration information. The configuration switching matrix contains the switching state corresponding to the magnetic switch 210. The high and low level outputs connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300 control the closed or open state of the magnetic rotating part 215 of the first magnetic switch 2101.

[0120] The second magnetic switch 2102 includes a magnetic rotating component 215. The magnetic rotating component 215 has a voltage withstand capability that can withstand the voltage requirements of the output signal line of the controller, and can be a high-power signal or a low-voltage signal. The magnetic rotating component 215 is supported by a spring to maintain the magnetic switch 210 in the open state.

[0121] The output port of the second magnetic switch 2102 is the second output port Out2. When the second magnetic switch 2102 is turned on, the controller signal is connected to the test bench through the second output port Out2.

[0122] The second magnetic switch 2102 is controlled by an iron core and a coil 214 wound around the iron core.

[0123] 214 is connected to the output of the two-dimensional matrix mapping controller 300. The input of coil 214 is a weak electrical signal. When coil 214 is energized, it can generate an attractive force sufficient to overcome the spring force, thereby causing the magnetic rotating part 215 of the second magnetic switch 2102 to close.

[0124] The terminals of the coil 214 of the second magnetic switch 2102 are connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300. The two-dimensional matrix mapping controller 300 can calculate the corresponding configuration switching matrix table, i.e., the two-dimensional matrix table, through the configuration information. The configuration switching matrix contains the switching state corresponding to the magnetic switch 210. The high and low level outputs connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300 control the closed or open state of the magnetic rotating part 215 of the second magnetic switch 2102.

[0125] The third magnetic switch 2103 includes a magnetic rotating component 215. The magnetic rotating component 215 has a voltage withstand capability that can withstand the voltage requirements of the output signal line of the controller, and can be a high-power signal or a low-voltage signal. The magnetic rotating component 215 is supported by a spring to maintain the magnetic switch 210 in the open state.

[0126] The output port of the third magnetic switch 2103 is the third output port Out3. When the third magnetic switch 2103 is turned on, the controller signal is connected to the test bench through the third output port Out3.

[0127] The third magnetic switch 2103 is controlled by an iron core and a coil 214 wound around the iron core.

[0128] 214 is connected to the output of the two-dimensional matrix mapping controller 300. The input of coil 214 is a weak electrical signal. When coil 214 is energized, it can generate an attractive force sufficient to overcome the spring force, thereby causing the magnetic rotating part 215 of the third magnetic switch 2103 to close.

[0129] The terminals of the coil 214 of the third magnetic switch 2103 are connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300. The two-dimensional matrix mapping controller 300 can calculate the corresponding configuration switching matrix table, i.e., the two-dimensional matrix table, through the configuration information. The configuration switching matrix contains the switching state corresponding to the magnetic switch 210. The high and low level outputs connected to the input / output (I / O) interface of the two-dimensional matrix mapping controller 300 control the closed or open state of the magnetic rotating part 215 of the third magnetic switch 2103.

[0130] The working principle of the second magnetic control switching component 2002 and the third magnetic control switching component 2003 is similar to that of the first switching component, and will not be described in detail here.

[0131] By combining the first magnetic control switching component 2001, the second magnetic control switching component 2002, and the third magnetic control switching component 2003, the switching between the controller-side signal and the test bench-side signal can be achieved.

[0132] The switching process is that the two-dimensional matrix mapping controller 300 automatically switches according to the configuration information through a pre-designed two-dimensional matrix table. The test operator only needs to confirm the corresponding configuration information in the two-dimensional matrix mapping controller 300 to achieve one-click switching.

[0133] In summary, this utility model's variable configuration test device for semi-physical simulation of aero-engine control systems achieves variable configuration testing through a magnetically controlled switching component 200 and a two-dimensional matrix mapping controller 300, solving the requirements for flexible adaptation and variable configuration semi-physical simulation. This utility model achieves variable configuration aero-engine controller testing through the control structure of the magnetic switch 210 and the design of the two-dimensional matrix mapping controller 300. A switching matrix is ​​established between the controller's input / output signals and the test bench's input / output signals, mapping the signal interconnection between the controller and the test bench into a two-dimensional matrix table. The control software can query the corresponding two-dimensional matrix table through configuration information and control the power signal on / off via the magnetic switch 210 to achieve weak control signals, thereby switching the cable box to the corresponding configuration.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
