Description

Technical Field

[0001] This utility model belongs to the field of CAN bus networks, and in particular relates to a storage and recording system that can store multiple data types. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, a storage recorder is a device that continuously and automatically acquires and saves field signals to a non-volatile storage medium over a long period of time. To ensure the versatility of storage recorders, most storage recorders on the market are based on the CAN bus and can only acquire and store CAN data.

[0004] However, due to the harsh working environment in the construction machinery industry, loose connections in vehicle wiring harnesses are common. However, the loose connection process is brief, and the fault may disappear after personnel arrive at the site, making it impossible to detect. Furthermore, wiring harness faults cannot be directly transmitted via CAN signals, so accurate fault data cannot be obtained, making it impossible to determine the type of fault. Summary of the Invention

[0005] To address at least one of the technical problems mentioned above, this utility model provides a storage and recording system capable of storing multiple data types. It reads various data related to wiring harness faults through the vehicle controller, including voltage data, resistance data, high and low level data, frequency data, etc., and transmits the acquired data to a CAN storage recorder for recording, allowing staff to view it. This achieves the acquisition and storage of multiple data types, overcoming the limitation of the vehicle controller's inability to continuously record data and compensating for the storage recorder's inability to acquire other data types.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a storage and recording system capable of storing multiple data types, including a vehicle controller and a CAN storage recorder; the vehicle controller is connected to the fifth port of the CAN storage recorder via a third port; the vehicle controller is connected to the sixth port of the CAN storage recorder via a fourth port.

The third and fourth wiring harnesses are then connected together to the power port of the OBD port.

[0014] In one implementation, the second port of the vehicle controller leads out a fifth wiring harness, and the eighth port of the CAN storage recorder leads out a sixth wiring harness. The fifth and sixth wiring harnesses are then combined and connected to the ground port of the OBD port.

[0015] In one implementation, the vehicle controller is provided with a voltage sampling port, a frequency sampling port, a resistance sampling port, and a high / low level sampling port.

[0016] The beneficial effects of this utility model are: This invention reads various data related to wiring harness faults through the vehicle controller, including voltage data, resistance data, high and low level data, frequency data, etc., and transmits the acquired data to the CAN storage recorder for recording.

[0028] Example 1 In the existing technology, if there is only a storage recorder, it can only collect CAN data and cannot collect other types of data; if there is only a vehicle controller, it can collect multiple types of data, but cannot store and record them.

[0029] To address the aforementioned issues, this embodiment provides a storage and recording system capable of storing multiple data types, comprising: a vehicle controller 1 and a CAN storage recorder 2; the vehicle controller 1 is provided with a third port and a fourth port, and the CAN storage recorder 2 is provided with a fifth port and a sixth port; the vehicle controller 1 is connected to the fifth port of the CAN storage recorder 2 through the third port; the vehicle controller 1 is connected to the sixth port of the CAN storage recorder 2 through the fourth port.

[0030] In a specific implementation, the third port of the vehicle controller 1 is connected to the fifth port of the CAN storage recorder 2 via the first wiring harness 4, and the fourth port of the vehicle controller 1 is connected to the sixth port of the CAN storage recorder 2 via the second wiring harness 5. The first wiring harness 4 is the CANL wiring harness, and the second wiring harness 5 is the CANH wiring harness.

[0031] In a specific implementation, an OBD port 3 is also included. The OBD port 3 includes a power port and a ground port, which are used to supply power to the vehicle controller 1 and the CAN storage recorder 2. The vehicle controller 1 also includes a first port and a second port, and the CAN storage recorder 2 also includes a seventh port and an eighth port.

[0032] Optionally, the first port of the vehicle controller 1 leads out the third wiring harness 6, and the seventh port of the CAN storage recorder 2 leads out the fourth wiring harness 7. The third wiring harness 6 and the fourth wiring harness 7 are then connected together to the power port of the OBD port 3.

[0033] The fifth wiring harness 8 is led out from the second port of the vehicle controller 1, and the sixth wiring harness is led out from the eighth port of the CAN storage recorder 2. The fifth wiring harness 8 and the sixth wiring harness 9 are combined and connected to the ground port of the OBD port 3.

[0034] In a specific implementation, the vehicle controller 1 is equipped with a voltage sampling port, a frequency sampling port, a resistance sampling port, and a high / low level sampling port.

[0035] When voltage signals need to be acquired and recorded, the voltage sampling port signal is connected in parallel to the wiring harness to be acquired. The vehicle controller 1 internally defines ID_1, which is used to convert the voltage value into a CAN signal and send it to the CAN storage recorder 2. This transmission occurs in 5ms frames. The CAN storage recorder 2 records the content transmitted under this ID. After the fault is reproduced, the CAN storage recorder 2 is connected to a computer to export the data, allowing analysis of the abnormal voltage state at the time of the fault.

[0036] When it is necessary to collect and record resistance signals, the resistance sampling port is connected in series with the wiring harness to be monitored. The software of the vehicle controller 1 will define ID_2, which is used to send the resistance value to the CAN storage recorder 2 in the form of a CAN signal.

[0037] When it is necessary to collect and record frequency signals, the frequency sampling port is connected in series with the wiring harness to be monitored. The software of the vehicle controller 1 will define ID_3, which is used to send the frequency value to the CAN storage recorder 2 in the form of a CAN signal.

[0038] When it is necessary to collect and record high and low level signals, the high and low level sampling ports are connected in series to the wiring harness to be monitored. The software of the vehicle controller 1 will define ID_4, which is used to send the frequency value to the CAN storage recorder 2 in the form of a CAN signal.

[0039] Working principle of this utility model: In existing technologies, if only a storage recorder is available, it can only collect CAN data and cannot collect other types of data. If only a vehicle controller is available, it can collect multiple types of data, but it cannot store and record them.

[0040] This invention utilizes a CAN wiring harness to connect the vehicle controller to a CAN storage recorder. The vehicle controller collects voltage, resistance, high / low level, and frequency data, and transmits the collected data to the CAN storage recorder. The CAN storage recorder records the received data for easy review by staff and to facilitate fault identification. This overcomes the limitation of the vehicle controller's inability to continuously record data and compensates for the CAN storage recorder's inability to collect other data types.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
