[0034] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0035] Example 1

[0036] This embodiment provides a STP locomotive garage detection wireless signal simulation device such as Figure 1 As shown, it includes a digital radio module I, a digital radio module II, an antenna I, an antenna II, a first frequency band configuration button, a second frequency band configuration button, a first vehicle host test button, a second vehicle host test button, a first configuration unit, a second configuration unit, a first vehicle host test unit, a second vehicle host test unit, a storage unit, a power switch and a power module. The antenna I is connected to the digital radio module I, and the antenna II is connected to the digital radio module II.

[0037] Preferably, the digital radio module I is MDS SD4, and the digital radio module II is MDS SD2.

[0038] The first configuration unit has built-in radio station configuration instructions in a first frequency band format.

[0039] The second configuration unit has built-in radio station configuration instructions in a second frequency band format.

[0040] The first vehicle-mounted host test unit has a built-in vehicle-mounted host test instruction in a first frequency band format.

[0041] The second vehicle host test unit has a built-in vehicle host test instruction in a second frequency band format.

[0042] The configuration interface of the data transmission radio module 1 is connected to the first configuration unit to receive a radio configuration instruction in a first frequency band format.

[0043] The data interface of the data transmission radio module 1 is connected to the first vehicle-mounted host test unit to receive the vehicle-mounted host test instruction in the first frequency band format.

[0044] The configuration interface of the data transmission radio module II is connected to the second configuration unit to receive radio configuration instructions in the second frequency band format.

[0045] The data interface of the data transmission radio module II is connected to the second vehicle-mounted host test unit to receive the vehicle-mounted host test instruction in the second frequency band format.

[0046] The first frequency band configuration button is connected to the first configuration unit, triggering the first configuration unit to send a radio station configuration instruction in the first frequency band format.

[0047] The second frequency band configuration button is connected to the second configuration unit, triggering the second configuration unit to send a radio station configuration instruction in a second frequency band format.

[0048] The first vehicle host test button is connected to the first vehicle host test unit, triggering the first vehicle host test unit to send a vehicle host test instruction in a first frequency band format.

[0049] The second vehicle host test button is connected to the second vehicle host test unit, triggering the second vehicle host test unit to send a vehicle host test instruction in a second frequency band format.

[0050] The power switch is respectively connected to the first configuration unit, the second configuration unit, the first vehicle-mounted host test unit, the second vehicle-mounted host test unit, the digital radio module I, the digital radio module II and the power module to control the power supply of the first configuration unit, the second configuration unit, the first vehicle-mounted host test unit, the second vehicle-mounted host test unit, the digital radio module I and the digital radio module II.

[0051] Furthermore, the first frequency band configuration button includes a first power adjustment button, and the second frequency band configuration button includes a second power adjustment button. When in use, the transmission power of the corresponding data transmission radio module can be adjusted respectively through the first power adjustment button and the second power adjustment button to simulate the scene of the STP vehicle-mounted device approaching or moving away from the ground transmission antenna.

[0052] Furthermore, it also includes a storage unit, which is communicatively connected to the first vehicle-mounted host test unit and the second vehicle-mounted host test unit respectively, and is used to store data received by the first vehicle-mounted host test unit and the second vehicle-mounted host test unit from the STP vehicle-mounted device to provide guidance for subsequent fault repairs.

[0053] It can be understood that the storage unit is also connected to the power switch to meet the power supply demand.

[0054] It can be seen that the utility model designs two digital transmission radio stations with different frequency bands, sets configuration buttons and vehicle host test buttons for different frequency bands, and builds different frequency band format instructions into the configuration unit and the vehicle host test unit. When in use, the configuration unit or the vehicle host test unit is triggered according to the corresponding buttons of different frequency bands to directly send the command information of the corresponding frequency band, thereby adapting to vehicle hosts of different frequency bands without the need to build a ground simulation test environment and without the need for additional computer and software data resource support.

[0055] It should be noted that even if different ground station equipment uses the same frequency band, the data packet format of their station information may be different. For this reason, the first vehicle-mounted host test unit is subdivided into vehicle-mounted host test units of different ground station equipment under the first frequency band, and the vehicle-mounted host test unit of each ground station equipment has a built-in vehicle-mounted host test instruction of the corresponding station data packet format under the first frequency band; the second vehicle-mounted host test unit is subdivided into vehicle-mounted host test units of different ground station equipment under the first frequency band, and the vehicle-mounted host test unit of each ground station equipment has a built-in vehicle-mounted host test instruction of the corresponding station data packet format under the second frequency band.

[0056] In one embodiment, if Figure 2 As shown, the first vehicle-mounted host test button and the second vehicle-mounted host test button are further subdivided into vehicle-mounted host test instruction buttons for different stations.

[0057] For example, the ground station equipment in the first frequency band includes ground station equipment I, ground station equipment II and ground station equipment III. Ground station equipment I, ground station equipment II and ground station equipment III belong to different STP manufacturers and therefore have different ground system station information data packets; the ground station equipment in the second frequency band includes ground station equipment IV, ground station equipment V and ground station equipment VI. Similarly, ground station equipment IV, ground station equipment V and ground station equipment VI belong to different STP manufacturers and therefore have different ground system station information data packets.

[0058] Therefore, the first vehicle-mounted host test unit and the second vehicle-mounted host test unit respectively include three ground station equipment simulation units and a convergence interface, each ground station equipment simulation unit has a built-in vehicle-mounted host test instruction of an STP manufacturer, and different ground station equipment simulation units have built-in vehicle-mounted host test instructions of different STP manufacturers; multiple ground station equipments of different STP manufacturers are connected to the data interface of the corresponding data transmission radio module through the convergence interface;

[0059] At this time, there are 6 corresponding vehicle-mounted host test buttons, namely vehicle-mounted host test buttons 1-6; among them, vehicle-mounted host test buttons 1-3 are test buttons corresponding to ground station equipment I, ground station equipment II and ground station equipment III respectively; vehicle-mounted host test buttons 4-6 are test buttons corresponding to ground station equipment IV, ground station equipment V and ground station equipment VI respectively.

[0060] Each vehicle-mounted host test command button is connected to the ground station equipment of the corresponding STP manufacturer.

[0061] When it is necessary to simulate the ground station equipment II under the first frequency band to send station information data to the corresponding STP vehicle-mounted equipment, press the vehicle-mounted host test button 2; when it is necessary to simulate the ground station equipment IV under the second frequency band to send station information data to the corresponding STP vehicle-mounted equipment, press the vehicle-mounted host test button 4.

[0062] In another possible embodiment, Figure 3 As shown, the first vehicle-mounted host test button and the second vehicle-mounted host test button are respectively multiple-choice switching switches, and the multiple-choice switching switches are arranged between the data interface of the first vehicle-mounted host test unit and the digital transmission and telegraph module I and between the data interface of the second vehicle-mounted host test unit and the digital transmission and telegraph module II.

[0063] At this time, the first vehicle-mounted host test unit and the second vehicle-mounted host test unit respectively include multiple ground station equipment simulation units, each ground station equipment simulation unit has a built-in vehicle-mounted host test instruction of an STP manufacturer, and different ground station equipment simulation units have built-in vehicle-mounted host test instructions of different STP manufacturers; multiple ground station equipment simulation units of different STP manufacturers are respectively connected to one gear position of the multiple-choice switch, and finally connected to the data interface of the corresponding data transmission radio module.

[0064] Still taking the above-mentioned ground station equipment in the first frequency band including ground station equipment I, ground station equipment II and ground station equipment III, ground station equipment I, ground station equipment II and ground station equipment III belong to different STP manufacturers; the ground station equipment in the second frequency band includes ground station equipment IV, ground station equipment V and ground station equipment VI, ground station equipment IV, ground station equipment V and ground station equipment VI belong to different STP manufacturers as an example, at this time, the first vehicle-mounted host test unit and the second vehicle-mounted host test unit respectively include three ground station equipment simulation units.

[0065] Correspondingly, the first vehicle-mounted host test button and the second vehicle-mounted host test button are three-select-one switching switches, including three gears, and each gear corresponds to a corresponding ground station equipment simulation unit.

[0066] The multiple input ends of the multiple-choice switch are respectively connected to different ground station equipment simulation units, and the output end of the multiple-choice switch is connected to the data interface of the corresponding digital transmission and telex module.

[0067] When it is necessary to simulate the ground station equipment II under the first frequency band to send station information data to the corresponding STP vehicle-mounted equipment, the first vehicle-mounted host test button is switched to the second gear position; when it is necessary to simulate the ground station equipment IV under the second frequency band to send station information data to the corresponding STP vehicle-mounted equipment, the second vehicle-mounted host test button is switched to the first gear position.

[0068] It can be understood that in actual applications, the ground station equipment of an STP manufacturer with the most STP vehicle-mounted equipment in the current station can be selected as the initial gear, so as to minimize gear switching and extend the service life of the vehicle-mounted host test button.

[0069] In a specific implementation, the STP locomotive garage internal wireless signal simulation device also includes a shell, and the digital radio module I, the digital radio module II, the first configuration unit, the second configuration unit, the first vehicle-mounted host test unit, the second vehicle-mounted host test unit, the storage unit and the power module are arranged in the shell, and the antenna I, the antenna II, the first frequency band configuration button, the second frequency band configuration button, the first vehicle-mounted host test button, the second vehicle-mounted host test button and the power switch are arranged on the shell.

[0070] In one embodiment, the STP locomotive garage internal wireless signal detection simulation device further includes a power management module, and the power management module is connected to the power module via the switch to obtain the voltage data of the battery and perform power monitoring.

[0071] In one embodiment, the STP motorcade in-house wireless signal detection simulation device also includes a display screen, which is respectively connected to the first configuration unit, the second configuration unit, the first vehicle-mounted host test unit, the second vehicle-mounted host test unit and the power management module to display the battery voltage data and the signal returned by the STP vehicle-mounted host received by the first vehicle-mounted host test unit and the second vehicle-mounted host test unit.

[0072] It can be understood that the first frequency band configuration button, the second frequency band configuration button, the first vehicle host test button, and the second vehicle host test button can be buttons with a physical structure or virtual buttons. When the first frequency band configuration button, the second frequency band configuration button, the first vehicle host test button, and the second vehicle host test button are buttons with a physical structure, the first frequency band configuration button, the second frequency band configuration button, the first vehicle host test button, and the second vehicle host test button are split structures with the display screen; when the first frequency band configuration button, the second frequency band configuration button, the first vehicle host test button, and the second vehicle host test button are virtual buttons, the first frequency band configuration button, the second frequency band configuration button, the first vehicle host test button, and the second vehicle host test button are integrated structures with the display screen, and at this time, the display screen is a touch display screen.

[0073] In one embodiment, the STP locomotive garage in-house wireless signal simulation device also includes a power LED indicator light, a configuration indicator light and a test indicator light, wherein the power LED indicator light is communicatively connected to the power management module; the configuration indicator light is communicatively connected to the first configuration unit and the second configuration unit; and the test indicator light is communicatively connected to the first vehicle-mounted host test unit and the second vehicle-mounted host test unit.

[0074] The power LED indicator light, the configuration indicator light and the test indicator light provide status indications for power supply, configuration status and test status.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
