The CAN Remote Control System (CAN RCS) sets new standards for the industry. When connected to a CAN network of the vehicle’s main computer or PLC, the CCM12 Receiver acts as a wireless gateway between the vehicle and the Operator Control Unit (OCU).
Laird Technologies CANopen Remote Control is made with safety and productivity in mind and it sets new standards for the industry. It is part of the new CattronControl products family. This CANopen Mining LHD system greatly simplifies the installation of a remote control on any CAN-based vehicle. When connected to a CAN network of the vehicle’s main computer or PLC, the Machine Control Unit (MCU) acts as a wireless gateway between the vehicle and the Operator Control Unit (OCU). All functions executed on the OCU are transferred on the CAN Network and vehicle vital signs are transmitted back to the OCU.
The system consists of two major components: the OCU, held by the operator, and the MCU, located on the vehicle to control. The system allows an operator to remotely control a CANopen LHD through a RF link.
The RF link provides two-way data transmission between the OCU and the MCU. RF telegrams are transmitted with the following characteristics:
The system is compatible with several Laird Technologies RF modules, each supporting a particular frequency band. RF channel can be pre-configured in Transkey configuration device (more details in next section), or selected by the operator.

The OCU is the interface to the operator. Each OCU can be custom engineered at our factory to meet specific customer’s needs. It comes in two different formats (Medium and Large Format). The Medium format, LRC-M1, can accommodate up to two joysticks plus several types of push buttons and toggle switches. The Large format, LRC-L1, can accommodate up to four joysticks and can accommodate even more types of push buttons and toggle switches. It is designed to withstand tough mining environments which may include humidity, oil, vibrations, and drastic differences in temperature. The OCU has the following features:
The OCU is powered by re-chargeable 4.8 V, 1600 mAh, Nickel Metal Hydride (Ni-MH) battery pack. An optional Battery Housing is available which holds two Type C Alkaline Batteries.
The MCU is the interface to the machine. It is enclosed in compact, watertight, impact resistant black nylon housing. The main connector is integrated to the front plate, ensuring sealed packaging. The main connector is PCB mounted, so there is no harness inside the housing, except for the RF cable. External dimensions (including connectors) are 145 x 138 x 48mm. The MCU main features are:
CANopen is a standardized protocol. CANopen operation for the actual implementation is summarized below:
In order to meet the requirements for safety-critical applications, a dual channel redundant architecture is implemented on both OCU and MCU. Both units have two processors: a Master processor and a Slave processor. The two processors perform similar operations on process data, and compare their results at specific check points in the process. If any inconsistency between the two processors is detected, or if any processor detects a failure, an error is declared and the system stops.
