Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, a vehicle mileage capturing and transmitting device according to an embodiment of the present invention is provided. Comprises an acquisition device, a wireless transmission module (a network antenna 3, a wireless network data processing circuit 8, a SIM card and the like) and a control system 12.
In at least some embodiments, the vehicle range capture and transmission device is directly connected to the OBD interface 1 of the automobile. The acquisition device is also in communication with the OBD interface 1 (OBD signal processing circuit 9) and acquires at least mileage data in the OBD system. The control system 12 will calculate the mileage of the vehicle based on the OBD mileage data.
In other embodiments, the acquisition device may include a GPS signal acquisition device (e.g., GPS antenna 4 and GPS signal processing circuit 5) that may be configured to acquire GPS signals in a manner known in the art, the GPS signal processing circuit 5 being in communication with the control system 12. The control system 12 combines the GPS signals and the OBD range data to calculate the vehicle's range.
In other embodiments, the in-vehicle range data may further be derived in conjunction with signals acquired by in-vehicle sensors, for example, the in-vehicle sensors may be acceleration sensors, the acquisition device may be further configured to process the acceleration signals (acceleration signal processing 6), and the control system 12 may calculate the range of the vehicle in conjunction with the acceleration signals, the GPS signals, and the OBD range data. In the process of vehicle driving, the GPS system is limited by signal interference when a satellite operates, so that the driving mileage is possibly inaccurate by calculating the driving mileage according to the GPS signal alone, the driving mileage is acquired by an acceleration sensor moving along with the vehicle by combining the acceleration signal, the driving mileage data can be corrected by combining the acceleration signal with the GPS as a mileage data source, and the acquired result is more accurate. In other embodiments, the signals collected by the vehicle-mounted sensor are processed to obtain the mileage data and are sent to the OBD interface, and the device receives the mileage data information from the OBD interface.
When multiple data sources are involved, some policy may be implemented to select the data source. For example, fig. 2 shows a selection strategy for multiple data sources, which may be accomplished by the following steps:
s101, after collecting the signal of the vehicle-mounted sensor, judging whether GPS positioning is available; if available, the satellite positioning data acquisition and satellite positioning data processing are executed, and then step 102 is executed, and if not, step S102 is directly executed.
S102: and judging whether the OBD interface is available, if so, acquiring vehicle-mounted mileage data and processing the acquired vehicle-mounted mileage data, and then executing the step S103, and if not, directly executing the step S103.
S103: and (5) performing multi-source information fusion processing to obtain final mileage data.
It should be noted that the device preferentially collects the mileage information on the OBD interface, and can calculate the mileage information by combining the GPS and the acceleration sensor information. If the vehicle does not have an OBD interface, GPS information is collected and can be calculated by combining with acceleration sensor information.
The control system 12 of the vehicle mileage capturing and transmitting device is connected to a dedicated server on the Internet network via a specific wireless network (e.g., via the wireless network data processing circuit 8 and the network antenna 3). The wireless communication network may be GPRS/3G/4G, which is described below as an example. If the GPRS connection is normal, the acquired mileage data is sent to a remote server in real time according to a certain strategy, and meanwhile, the mileage data is stored in a local memory 11 of the vehicle mileage real-time capturing and transmitting device according to a certain strategy. In addition, a unique identifier (such as an ID) can be given to the vehicle on the remote server, the corresponding relation between the ID and information such as the license plate number of the automobile can be set, and if necessary, the identifier of the vehicle can be associated with an identification icon such as a two-dimensional code. When the emission detection equipment detects, the identification of the vehicle can be identified and read through various methods, and the mileage data corresponding to the vehicle and the identification of the vehicle in the server can be automatically read. For example, the vehicle license plate number or ID may be entered in the software of the emission detection device to establish a connection with the vehicle mileage data module in the database, or the vehicle mileage data matching the two-dimensional code may be read by scanning the vehicle two-dimensional code to connect to the vehicle mileage database in the server. This prevents intentional misreading during manual operation. The reason why the mileage data is stored in the local memory is that the data is easily influenced by network conditions to cause the problems of packet loss and frame loss in the process of uploading the data to the remote server, at this time, the emission detection equipment can also communicate with a vehicle-mounted vehicle mileage real-time capturing and transmitting device during detection, and the mileage data is read from the local memory as a reference.
Fig. 3 illustrates a saving method performed by the control system, taking the example that the mileage data is simultaneously uploaded to the server and saved to the local storage, and the method includes:
s201: judging whether the wireless network is available, if so, connecting the server, then sending a data module, and finally executing S202; if not, the user is prompted for a network anomaly and then proceeds directly to S202.
S202: and judging whether the local memory is available, if so, writing the mileage data into the local memory module, and if not, sending a fault prompting signal (such as a control fault lamp for lighting) to a user.
In some embodiments, the control system further comprises a power down protection module. The power-down protection module is at least used for detecting whether the vehicle mileage capturing and transmitting device is powered down or not, and sending prompt information to a server through the wireless transmission module when the power-down is detected. Therefore, when the emission device is detected, the power-down record of the vehicle can be read from the server, whether the mileage data is accurate or not is judged, and misleading of detection personnel by a manual closing device is prevented. In some other embodiments, the power down protection module is further configured to write the hint information to a local memory. Thus, when the server does not receive the power-down prompt message due to the network condition, the emission detection device can obtain the power-down record by directly reading the content of the local storage.
The vehicle mileage capturing and transmitting device comprises a main power supply (such as a power supply circuit 7), and the main power supply can be independent or connected with the vehicle-mounted cigarette lighter interface 2 and powered by a vehicle-mounted power system. Further, in some embodiments, the vehicle range capture and transmission device further comprises a backup power source (which may be integrated in the power down protection circuit 10 or in communication with the power down protection circuit 10), and the power down protection module is further configured to use the backup power source to supply power when a power failure is detected. This prevents an accidental power failure or deeming the vehicle mileage capturing and transmitting device to be turned off. In other embodiments, there are two situations, one is a general power down, and the other is an accidental power down when the calibration tool is connected. If the power is general power failure, setting a power failure mark, then setting a fault state mark, writing the current mileage information into a local memory, and sending the current mileage information to a network server.
Fig. 4 shows a calibration method during power down protection, in which it is required to first determine whether the calibration state is present,
if the mobile terminal is not in the calibration state, calculating mileage, storing and uploading mileage data, and setting a power failure mark and a fault mark;
if the power failure flag is not completed, the power failure flag is set.
Also shown in fig. 5 is a self-test method performed by the control system, the method being performed prior to calculating mileage and comprising the steps of:
s301, after the vehicle mileage capturing and transmitting device is powered on, firstly, hardware self-check is carried out, whether the hardware is normal or not is judged, if not, a fault lamp is started to prompt a user, and if the hardware is normal, the step S302 is executed.
S302, judging whether the network is normal, if not, starting a fault lamp, and if so, executing the step S303.
S303: and judging whether power is lost once, if so, starting a fault lamp, sending warning information to the server, and writing the warning into the local server.
The embodiment of the invention provides a vehicle mileage capturing and transmitting method, which mainly adopts the following steps:
the method comprises the following steps: acquiring data of the driving mileage; the driving mileage data is obtained by at least acquiring OBD mileage data and calculating according to the OBD mileage data;
step two: transmitting the mileage data to a server in real time through a wireless transmission manner, so that the server stores the received mileage data and the emission detection device downloads the mileage data from the server; and
step three: and detecting whether the vehicle mileage capturing and transmitting device is powered off or not, and sending prompt information to a server through a wireless transmission module when the power failure is detected.
Through the steps, the mileage data can be stored on the server in real time, the emission detection equipment can automatically read the mileage data, and the power failure protection can avoid manual closing of the device. The authenticity of the mileage data is ensured.
Wherein:
in the first step, the vehicle-mounted sensor signal (such as an acceleration signal) and the GPS signal can be fused to calculate the driving mileage of the vehicle; the policy shown in fig. 2 may be implemented when making the selection of the data source.
In step two, the mileage data may be written into the local memory, and the saving method shown in fig. 3 may be performed.
