Abstract
A system and method for processing instructions sent wirelessly between a control master unit and a slave device comprising a slave device memory is disclosed. The control master unit transmits an instruction to the slave device. The slave device writes the received instruction to the slave device memory; reads a stored instruction, corresponding to the instruction written to the memory, from the memory; and transmits the stored instruction to the control master unit. The control master unit compares the stored instruction to the instruction and, if the stored instruction is the same as the instruction, enables a process instruction to be sent to the slave device. In response to receiving the process instruction, the slave device processes the stored instruction.
Claims21
A system comprising:
- a slave device comprising a readable and writeable slave device memory, a slave device processor, and a slave device transmitter-receiver;
- and
- a control master unit for controlling the slave device, the control master unit comprising a control master unit readable and writeable memory, a control master unit processor, and a control master unit transmitter-receiver, wherein:
- the slave device and the control master unit are capable of communicating wirelessly with each other via their respective transmitter-receivers;
- the control master unit processor is configured to:
- transmit via the control master unit transmitter-receiver, to the slave device, a wireless command signal containing a command instruction;
- the slave device processor is configured to:
- write the command stored instruction to the slave device memory to create a stored instruction, the slave device being configured to store only a single instruction in the slave device memory at any one time, wherein, after a first command instruction is stored and a second command instruction is received from the control master unit, the second command instruction over-writes the first command instruction;
- read the stored instruction from the slave device memory;
- and
- transmit via the slave device transmitter-receiver, to the control master unit, a wireless response signal containing the stored instruction;
- the control master unit processor is further configured to:
- compare the stored instruction to the command instruction;
- and, only if the stored instruction is the same as the command instruction, send a process instruction via the control master unit transmitter-receiver to the slave device.
A method of operating a system, the system comprising a slave device comprising a slave device memory and a control master unit for controlling the slave device, wherein the slave device and the control master unit are capable of communicating wirelessly with each other, the method comprising:
- transmitting, from the control master unit to the slave device, a wireless command signal containing a command instruction;
- at the slave device:
- writing the command instruction to the slave device memory to create a stored instruction, the slave device being configured to store only a single instruction in the slave device memory at any one time, wherein, after a first command instruction is stored and a second command instruction is received from the control master unit, the second command instruction over-writes the first command instruction;
- reading the stored instruction from the slave device memory;
- and
- transmitting, to the control master unit, a wireless response signal containing the stored instruction;
- at the control master unit:
- comparing the stored instruction to the command instruction;
- and
- only if the stored instruction is the same as the command instruction, sending a process instruction to the slave device.
