CPDEVICE Rugged Mining Tablet: Ultra-Sensitive and High-Pressure Resistant Communication Capability

In the mining operation process, due to the large mining area, widespread unloading points, complex terrain, and other reasons, the dispatch and management of the transport fleet have long been a challenging issue. Remote scheduling control and collection of vehicle and driver information are the current common management methods in mining areas; solving vehicle safety, efficient driving, and operational pain points through technological upgrades and intelligent means will be the next "big opportunity" in mining areas. These are all important application directions for CPDEVICE's software and hardware solutions.

Solving the informatization of vehicle dispatch and management is a significant test for the communication capabilities of onboard devices, especially in harsh and extreme environments. This requires devices to have high-speed stable communication, various communication methods, low-latency real-time communication, communication security, and the ability to withstand harsh environments. Taking CPDEVICE's APOLLO 12 PRO as an example, let's see how CPDEVICE addresses communication issues.


01 High-pressure resistant CAN bus

The CAN bus is a half-duplex communication method. When a CAN controller needs to send and receive data, the ECU with the CAN controller has to receive and process the data, thus a high CAN load can significantly challenge the controller's receiving capacity. The advantages of CAN communication in mining machinery include:

  1. Strong real-time performance: CAN communication has high real-time performance, capable of completing data transmission at the microsecond level, suitable for real-time control and feedback applications in mining machinery, such as vehicle control and sensor data collection.

  2. Strong anti-interference capability: The CAN communication protocol uses differential signal transmission and non-blocking communication mechanisms, which have strong anti-interference capabilities suitable for harsh mining environments and can reliably transmit data.

  3. Supports multiple device connections: The CAN bus structure can support multiple devices connected on the same bus, forming a distributed control system suitable for situations in mining machinery systems with multiple control nodes, simplifying system architecture and reducing wiring costs.

  4. Low cost: The CAN communication protocol is a mature communication standard with many mature products and solutions available on the market. The hardware cost is relatively low, suitable for cost-sensitive scenarios in mining machinery applications.

  5. Easy to integrate and maintain: The CAN communication protocol has standardized and modular characteristics, making it easy to integrate equipment from different manufacturers and facilitate system maintenance and expansion.

To address issues such as message anomalies and frame loss caused by instantaneous high loads, CPDEVICE has upgraded its entire product line to achieve stable communication under high CAN loads. Tests have shown that CPDEVICE's products can simultaneously send and receive via 2 CAN communications and perform stably under up to 80% load.

Moreover, with the support of the new generation cross-process CPComm, the new generation intelligent tablet APOLLO 12 PRO equipped with 4-way SocketCAN by CPDEVICE can achieve ultra-high speed + 70% load without frame loss, utilizing load balancing design to fully leverage the chip's multi-core characteristics. In extreme cases, when a single process requires high load, CPU multi-cores can be pushed to near saturation, significantly improving performance compared to the past single-core operations.

CAN bus characteristics:

  • Low cost
  • Long data transmission distance (up to 10km)
  • High data transmission rate (up to 1M for Classic CAN, up to 12M for CAN FD)
  • Non-destructive priority-based bit-wise arbitration
  • Multiple address frame delivery through acceptance filters
  • Remote data requests
  • Reliable error detection and fault handling capabilities
  • Automatic retransmission after information corruption
  • Temporary errors, permanent fault node identification, and automatic disconnection from the fault point
  • Nodes disconnected from the bus do not affect the normal operation of the bus


02 Ultra-sensitive 5G communication

CPDEVICE's new generation intelligent tablet APOLLO 12 PRO features ultra-sensitive 4G/5G communication capabilities, ensuring communication quality in low-density, weak signal coverage areas. Mining with 5G technology can enhance safety, production efficiency, and management levels, bringing efficient and reliable operational capabilities to the industry.

  1. Enhances safety and monitoring performance: The 5G network can support more sensors and monitoring devices, real-time monitoring of conditions inside the mine, including geological changes, equipment status, worker safety, etc. This can help prevent accidents and improve mine safety.

  2. Improves production efficiency: With 5G technology, mines can achieve more efficient equipment communication and data transmission, thereby increasing production efficiency. For example, real-time communication and collaboration between devices can optimize the mineral extraction process and reduce downtime.

  3. Realizes automation and intelligence: The 5G network can support more intelligent devices and automation systems, helping mines to achieve automated production and intelligent management. This can reduce dependency on human labor and improve the sustainability and consistency of production.

  4. Provides better communication coverage: Traditional mine environments may face issues with inadequate communication coverage, while 5G networks can provide broader and more stable communication coverage, ensuring unimpeded communication throughout the mine.

03 New generation cross-process CPComm

CPComm: CPDEVICE's proprietary bus system, allowing users to easily perform secondary development. The system mainly includes industry protocol modules, basic protocol modules, data link modules, and port modules, with data flowing bidirectionally between modules. The new generation CPComm, designed for data interaction with multiple clients, can perform multi-process collaborative computing, maximizing the utilization rate of CPU multi-core resources. After using the new generation cross-process CPComm, we were surprised to find that product performance has not just improved; it has significantly exceeded hardware limitations.

In addition to excellent communication capabilities, CPDEVICE's new generation intelligent tablet APOLLO 12 PRO also supports Gigabit Ethernet and can support up to 2 RS232 or 1 RS232 and 1 RS485. CPDEVICE's software and hardware solutions feature high-speed communication, long-distance transmission, strong anti-interference capabilities, easy integration, and a wide range of rich applications, making it a great partner for mining machinery.
