What Kinghelm Products Are Applied in Automotive “Two Passenger & One Hazardous” Ministry-Standard Terminals?

Kinghelm’s products are widely applied in automotive “Two Passenger & One Hazardous” Ministry-standard terminals—special vehicle supervision devices based on the BeiDou Satellite Navigation System. These applications focus on three core requirements: signal transmission, positioning and navigation, and device interconnection. The specific products and application scenarios are as follows:

 

I. BeiDou / GPS Dual-Mode Antennas: Core Components for Positioning and Signal Reception

Antennas are key components enabling BeiDou positioning, navigation, and signal interaction in “Two Passenger & One Hazardous” ministry-standard terminals. Kinghelm provides multiple high-performance antenna solutions tailored to positioning accuracy, anti-interference capability, and multi-scenario adaptability.

1. Dual-Mode Positioning Support

Core products such as the KH1GBC-01 antenna support BeiDou (BDS) and GPS dual-mode signal reception. Through bidirectional calibration of navigation signals, they ensure high positioning accuracy for “Two Passenger & One Hazardous” vehicles—including tourist coaches, long-distance buses, and hazardous materials transport vehicles—even under complex road conditions, avoiding positioning deviations caused by weak single-system signals.

Another model, the KH-DW-K580-WZ antenna, covers the main operating frequency bands of BeiDou (1561 ±2 MHz) and GPS (1575.42 ±2 MHz), fully meeting the dual-mode positioning requirements specified for ministry-standard terminals.

2. Strong Anti-Interference Performance and High Signal Quality

Using RHCP (Right-Hand Circular Polarization) designs (such as the KH-DW-K580-WZ and KH1GPC-01 antennas), these products effectively reduce signal interference from complex electromagnetic environments encountered during vehicle operation—such as high-voltage power lines and other onboard electronic devices—ensuring stable and reliable positioning data.

Some antennas (e.g., KH1GBC-01) feature a noise figure below 1.3, an LNA (Low Noise Amplifier) gain of up to 29 ±2 dB, and a Z-axis gain of 2 dBi, significantly improving signal reception sensitivity in weak-signal environments such as tunnels and mountainous areas, thereby preventing positioning interruptions.

3. Adaptation to Special Application Scenarios

For extreme scenarios without mobile network coverage—such as remote transportation routes—Kinghelm has developed BeiDou Generation-1 B3 band antennas. When paired with the ministry-standard terminal’s short message communication function, these antennas enable offline data transmission between vehicles and monitoring centers, ensuring uninterrupted regulatory supervision.

II. RF and Microwave Connectors / Interconnect Products: Signal and Device Connection Hubs

“Two Passenger & One Hazardous” ministry-standard terminals need to connect multiple components, including BeiDou antennas, 4G/5G communication modules, and onboard sensors. Kinghelm’s connectors and interconnect products serve as the core infrastructure enabling stable interconnection among these modules:

1. Standardized Interface Compatibility

2. Non-Standard Customization Support

3. Multi-Module Coordinated Interconnection

III. Switch Products: Device Control and Functional Switching

Kinghelm’s switch products provide hardware support for power control, function activation, and parameter adjustment in “Two Passenger & One Hazardous” ministry-standard terminals, ensuring reliable and stable device operation:

1. DIP Switches

2. Tactile Switches

3. Slide Switches

IV. Coordinated Applications with Related Vehicle Devices

In addition to direct integration with ministry-standard terminals, Kinghelm products can also operate in coordination with other core vehicle devices—such as T-BOX and OBD systems—to form a comprehensive intelligent vehicle supervision ecosystem.

Integration with T-BOX (Telematics Control Unit)

By utilizing BeiDou / GPS antennas and Wi-Fi antennas (including Kinghelm PCB antennas and ceramic chip antennas), Kinghelm products support T-BOX functions such as remote vehicle control and UBI insurance data collection, supplementing ministry-standard terminals with additional remote vehicle monitoring data.

Interconnection with OBD (On-Board Diagnostics)

Through connectors linking OBD sensor interfaces, vehicle fault data (such as engine abnormalities) can be transmitted from the OBD system to the ministry-standard terminal and then synchronized to regulatory platforms. This assists supervisory authorities in assessing vehicle safety conditions and provides data support for vehicle maintenance and repair in the era of intelligent driving.
