Description

Technical Field

[0001] The utility model belongs to the field of tractor reliability monitoring devices, in particular to a tractor reliability monitoring data storage device. Background Art

[0002] The equipment used for tractor reliability monitoring generally needs to collect operation image data through front and rear cameras, collect engine speed, fuel consumption, and torque data through CAN modules, and collect vehicle position and speed data through GNSS modules. These data are aggregated and stored in the SD card after entering the main control MCU, and then uploaded to the cloud processing platform through the 4G module.

[0003] It can be seen that the tractor reliability monitoring equipment needs to store a large amount of raw data, and the tractor reliability test often takes several months. The SD card is often full and the raw data is lost. At the same time, since the MCU can only recognize a maximum of 32G SD card, it is impossible to solve the storage problem by expanding the SD card to a larger size. Utility Model Content

[0004] The utility model aims to provide a tractor reliability monitoring data storage device, which realizes the expansion of storage space through a time-division multiplexing circuit.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tractor reliability monitoring data storage device, comprising a device body, the device body comprising an MCU module, a multiplexing switch, a power module and a plurality of SD card slots; the power module is used to supply power to the MCU module, the multiplexing switch and the plurality of SD card slots at the same time; the input end of the multiplexing switch is connected to the MCU module, and the output end is respectively connected to the plurality of SD card slots;

[0006] The multiplexing switch includes a data input end, an actuator and a data output end; the data input end includes a data input port and multiple control input ports, and the data output end includes multiple data line output ports; the number of the control input ports and the data line output ports is the same as the number of SD card slots, the data input port is used to receive data to be stored, and the data line output port is used to transmit data to the SD card in the corresponding SD card slot; the number of the actuators is the same as the number of SD card slots, and the actuators are connected to the data input end and the corresponding data line output ports.

[0007] The actuator includes a control input terminal, input contacts, output contacts, a synchronous switch, an electromagnetic switch and a control circuit. The input contacts, output contacts and synchronous switch are all set to multiple channels of the same number. The synchronous switch is used to achieve corresponding connection of the input contacts and the output contacts; the control input terminal is used to receive a control signal and transmit it to the control circuit. The control circuit is connected to the electromagnetic switch. The electromagnetic switch is used to control the linkage action of multiple synchronous switches to achieve corresponding connection of multiple input contacts and the output contacts.

[0008] The SD card slots are set to three, namely SD1 slot, SD2 slot and SD3 slot; the multiple control input ports are respectively 1-way control input port, 2-way control input port and 3-way control input port; the multiple data line output ports are respectively 1-way data line output port, 2-way data line output port and 3-way data line output port.

[0009] The actuator has six input contacts, six output contacts and six synchronous switches.

[0010] The beneficial effect of the utility model is that the utility model is not subject to the limit of the MCU on the storage capacity of the SD card, and only one MCU is needed to realize the expansion of data storage, so as to meet the data storage requirements during the long-term tractor reliability test.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0017] like Figure 1 As shown, a tractor reliability monitoring data storage device, the device body includes an MCU module 2, a multiplexer switch 3, a power module 4 and an SD card slot.

[0018] The power supply module is used to supply power to the MCU module 2, the multiplexer switch 3, and the SD card slot simultaneously, and even the SD card slot that is not in use needs to be powered.

[0019] The SD card slot is used to insert the SD card required for storing data, and the SD cards used must be of the same brand and capacity. The utility model is provided with three SD card slots.

[0020] The input end of the multiplexing switch 3 is connected to the MCU module 2, and the output end is connected to three SD card slots respectively.

[0021] like Figure 2 As shown, the multiplexer switch 3 is composed of a data input terminal, an actuator, and a data output terminal. The data input terminal includes a data input port 11 and three control input ports, which are respectively a 1-way control input port 8, a 2-way control input port 9, and a 3-way control input port 10; the data output terminal includes three data line output ports, which are respectively a 1-way data line output port 15, a 2-way data line output port 16, and a 3-way data line output port 17; the actuator is used to receive a control input signal and connect the control data input port 11 with the corresponding data line output port, so the actuator is divided into a 1-way control actuator 12, a 2-way control actuator 13, and a 3-way control actuator 14, which are respectively used to connect the control data input port 11 with the 1-way, 2-way, and 3-way data line output ports.

[0022] When working, the MCU module 2 sends an enable signal to one of the control input ports, controls the corresponding actuator to connect the data input port 11 and the corresponding data line output port, and starts to store data.

[0023] like Figure 3 As shown, the structure of the actuator includes a control input terminal 23, an input contact 18, an output contact 19, a synchronous switch 20, an electromagnetic switch 21 and a control circuit 22, wherein the input contact 18, the output contact 19 and the synchronous switch 20 are all set to the same number, and in this embodiment, they are all set to 6. When the control signal enters the control circuit 22 through the control input terminal 23, the control circuit 22 controls the electromagnetic switch 21 to close, and the electromagnetic switch 21 drives the 6-way synchronous switch 20 to work together, so that the 6-way input contacts 18 and the 6-way output contacts 19 are connected at the same time, thereby realizing the connection between the data input port 11 and the corresponding data line output port.

[0024] In this embodiment, the actuator has 6 input contacts and 6 output contacts. When the control input terminal is enabled, the 6 input and output contacts are connected simultaneously. In other embodiments, the number of input contacts and output contacts in the actuator is determined according to actual conditions.

[0025] During use, the utility model can adopt the following storage modes:

[0026] (1) When the storage mode of switching to the next SD card after one SD card is full is adopted, the storage device works as follows: MCU module 2 receives the storage data sent by other devices, and then sends the SD capacity query instruction to the SD card to be stored through the multiplexing switch 3. If there is capacity, the stored data is sent to the SD card for storage. When the capacity is full, MCU module 2 sends the SD capacity query instruction to another SD card through the multiplexing switch 3 again. If there is capacity, it switches to the next SD card for data storage.

[0027] (2) When adopting the mode of storing different data in different SD cards, the working process of the storage device is: MCU module 2 receives the storage data sent by other devices, and then classifies and identifies the data. MCU module 2 sends the corresponding control input command to the multiplexer switch 3 to store the data in the corresponding SD card.

[0028] This embodiment further illustrates the solution of the utility model by taking three SD card slots as an example. It can be understood that in a specific implementation, under the design concept of the utility model, a multiplexing switch can be set according to the number of SD card slots to realize the storage of a large amount of data in the tractor reliability test.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
