Description

Data gateway for data conversion confluence signals

This invention relates to a network gateway, and more particularly to a network gateway for an unrestricted meter type to establish a communication conduit between a vehicle device and a meter.

In the prior art, in order to ensure the safety of the own vehicle, improve the driving performance of the vehicle, or avoid theft of the vehicle, an additional engine such as a revolution meter (RPM) and a turbocharger (Turbo) are added. Boost Pressure Gauge), external thermometers such as engine thermometers, alarms, Global Position System (GPS), Multimedia Device (Video Device/Audio Device), or driving recorders.

However, in order not to damage the original design of the car, the technician will configure the sensor of the meter on the relevant device, equipment or line. What's more, the technician cuts the line of the vehicle equipment according to the demand to connect the meter to the relevant vehicle equipment.

However, in today's car design, the vehicle network (such as CAN-BUS) is normally configured, and the vehicle equipment and the vehicle computer connected to the vehicle network are mostly digital devices, which are transmitted and transmitted on the vehicle network. The signal is a communication signal.

However, the commonly used meters are mostly analog meters, which cannot be linked and communicated with the vehicle network and their vehicle equipment. Therefore, a digital meter is needed and the digital meter is constructed as another additional vehicle. Using the network, the two vehicles are electrically coupled to each other, so that the vehicle equipment, the vehicle computer and the meter on the two vehicle networks can communicate with each other via broadcast communication signals to establish mutual communication behavior. Or, the analog meter is combined with a digital/analog conversion circuit (D/A Converter), and then the meters are constructed as the above-mentioned additional vehicle network, and then linked with the original vehicle network to obtain the vehicle. The communication signal transmitted by the device.

Therefore, it is known that it is difficult to establish an additional vehicle network or to configure a sensor on a vehicle device (or to trim a line to connect a meter). First: the sensor is mostly analog or high voltage type, so it needs to be equipped with protection circuits such as degaussing and voltage regulation. If any circuit is installed incorrectly, it may cause damage to the relevant vehicle equipment. Even more so, it is not surprising that the car is burned. Technicians need to have considerable expertise and technical experience to be able to carry out. The overall test and installation process is very complicated, which increases the difficulty of installation, which is time consuming, laborious, costly and unsafe. Second: Although it is convenient to establish another vehicle network, the technician must cooperate with the operation mode of the vehicle network to use a digital meter or an analog meter with a digital/analog conversion circuit. The equipment cost of the meter will rise sharply, and it is limited by the transmission mode of the communication signal, which will reduce the willingness of the owner to install the meter.

Therefore, how to unconstrain the type of meter and combine the meter with the vehicle network is a problem that manufacturers should consider.

The problem to be solved by the present invention is to provide an intermediary device that is disposed between the meter and the vehicle network so that the meter operates in response to the relevant vehicle equipment to display relevant information.

In order to solve the above-mentioned equipment problem, the present invention discloses a network gateway for data conversion of a sink signal, which is connected between at least one vehicle device (Car Device) and at least one gauge (Gauge). The network gateway includes at least one signal receiving module, a gateway control module and a signal sink output port.

Each signal receiving module is connected to the above-mentioned vehicle equipment to obtain at least one communication signal transmitted by the vehicle equipment. The gateway control module is configured to connect all the signal receiving modules to obtain communication signals transmitted by the respective vehicle devices, and adjust the logic data by using one of the pre-stored signals to convert the communication signals into at least one instrument control signal. The signal sink output port is used to connect the aforementioned meters, and the meter control signal is transmitted from the gateway control module through the signal sink to be transmitted to the corresponding meter.

Among them, according to the type of the meter, the gateway controller generates an instrument control signal corresponding to the type of the meter. When the meter is an analog meter, the instrument control signal generated by the gateway controller is an analog signal; when the meter is a digital meter, the instrument control signal generated by the gateway controller is a digital signal. Secondly, when the number of the meters is two or more, the gateway control module transmits the meter control signals to the signal sink output ports, so that they substantially synchronously output the meter control signals to the corresponding meters.

The invention is characterized in that it is not limited to the type of the meter, and the meter is ingeniously combined with the vehicle network, regardless of the analog or digital type of meter. Secondly, the gateway control module outputs the instrument control signals to the meters through the signal convergence output to substantially synchronize (eg, within the same duty cycle) to form an analog vehicle network form, and each meter is substantially At the same time, the correct working value and the meter change mode are displayed, which is beneficial for the user to correctly correct the correct operation of the vehicle.

The signal receiving module 21 is configured to connect the vehicle devices 10 and obtain at least one communication signal 51 transmitted by each of the vehicle devices 10. The communication signal 51 obtained by the signal receiving module 21 is different depending on the connection method. (1): As shown in FIG. 2A, when the communication mode is diagnosed, the signal receiving module 21 obtains the diagnostic signal; (2): when the vehicle is in the network communication mode, the signal receiving module 21 obtains the broadcast of the vehicle device 10.

A signal adjustment logic data 40 is pre-stored in the gateway control module 22, and the gateway control module 22 uses the signal to adjust the logic data 40 to convert the received communication signal 51 into at least one meter control signal 53.

The signal sink output port 23 includes more than one port, each port for more than one meter (regardless of the analog meter 31 or the digital meter 32), and moreover, each port is for liquid crystal monitoring. Device 33, mobile phone, navigation machine, anti-theft device, etc. related types of electronic devices 34. As long as the network gateway 20 can communicate with it, it is not limited to the above electronic device 34.

The signal sink output port 23 is configured to connect the gateway control module 22 and the aforementioned meters to output the meter control signal 53 output by the gateway control module 22 to the corresponding meter.

The gateway control module 22 outputs a matching type of instrument control signal 53 according to the type of the connected meter. For example, when the meter includes an analog meter, the meter control signal 53 output by the gateway control module 22 is The method includes controlling at least one analog signal of the analog meter; for example, when the meter includes the digital meter, the meter control signal 53 output by the gateway control module 22 includes at least one digital signal for controlling the digital meter.

Wherein, the class determination manner of the meter is as follows: (1) the built-in analysis circuit of the gateway control module 22 analyzes the device type of the meter through the signal sink output port 23; (2) is established on the network gateway 20 A control interface that sets the meter type by the user.

3A is a schematic diagram showing the structure of the network gateway device of the present invention and FIG. 3B is a schematic diagram showing the signal conversion of the network gateway device of the present invention. In this embodiment, the detailed structure of the gateway control module 22 is disclosed. The gateway control module 22 includes a storage module 223, a signal adjustment module 221 and a signal type conversion module 222.

The storage module 223 is configured to store the signal adjustment logic 40, and the signal adjustment module 221 performs operation on the received communication signal 51 to obtain at least one instrument control parameter 52, and the signal type conversion module. 222 is then based on the meter (or type of associated electronic device 34) to convert meter control parameters 52 to meter control signals 53 corresponding to the respective meters.

The signal adjustment logic 40 includes at least two types of data: (1) the signal adjustment logic 40 includes a communication signal 51 transmitted by the vehicle device 10, which includes a numerical range of operational values, and the gateway control module 22 The resulting numerical range of meter control parameters 52 and the operational formula for adjusting communication signal 51 to meter control parameter 52. For example, when the upper limit value of the working value of the communication signal 51 is 20 and the lower limit value is 14, the upper limit value of the numerical value range of the instrument control parameter 52 (for example, the voltage value) is 10V, and the lower limit value is 5V.
