About Us

BELVES Design Pty Ltd is a small design consultancy, based in Albury on the New South Wales -Victoria border in South-East Australia.

We have extensive experience in systems review, analysis, and design, data processing and electronics design, analysis and production and software design and production.

Electronic design expertise includes work in analogue signal processing, digital signal processing, portable microprocessor based machine controllers, intelligent communications controllers, PLCs, User Interface Design, Command Control and Communication systems of all types.

Process and procedure design review and analysis include work, control and data flow analysis in electronics, manufacturing, and office processes. We can find bottle necks and increase throughput and productivity through modified use of existing processes and innovative development of new processes.

Our ability to design electronics sensor and actuator systems, smart controllers, network data and control paths, and control systems and software make us integration ninjas.

We have experience in circuit design for analogue signal processing, mixed analogue and digital signal processing systems, motor control systems, and battery powered portable systems. Real time systems, complex controls, fancy data handling, are all standard for us; tell us your requirements and constraints and we’ll show you the solution.

Process control, information control, and change management are all routine considerations for us.
We can provide advice and support to help you manage your research, development, and innovation to maximise your return on investment.

Projectile Location System

Software design, system architecture, communication design, data flow, timing analysis, real time control and analysis, distributed processing, data analysis in real time, distributed information display, built in monitoring and analysis systems. This system has it all.

A Control Computer allows the operator to control 12 display and data collection computers, and 96 analysis and control systems. Each display and data collection computer communicates with two data collection processors that collect data. Each analysis and control system consists of a custom made processor PCB with three sub processors each controlling different hardware, and a central analysis system collecting multiple data channels with nanosecond resolution. All hardware platforms were programmed. All communication paths were defined to allow sufficient throughput in real time. All data was collected analysed and presented in real time. Five different programming languages. Complex three dimensional data analysis algorithms developed. All systems synchronised to within 1ms across the control network, 120m wide and 700m long.

When a rifle is fired the firing time is detected and recorded in milliseconds, at up to 2000 events per second. When a projectile passes a sensor the time of the projectile arrival (in milliseconds) and the sound arriving at each sensor (in nanoseconds) is recorded. All this data is sent back to the control computer and analysed, then sent to the display and data collection computers for graphical display.

All systems, processes, procedures, events, data structures, protocols, algorithms developed and coded by BELVES Design for RYTMAR Technologies.

Alternator Control Electronics

A 28V DC Alternator capable of producing 500 Amps.

This is a specialised alternator developed to meet the requirements of the Australian, British, Canadian, and US Defence Forces.

In order to produce this much power the alternator is water cooled, and has an embedded microprocessor controlling the outputs. The embedded controlled has to survive inside the alternator, and control the very high power outputs, while monitoring the alternator operation to
stay inside the alternator SOA (Safe Operating Area) and protect the alternator from external loads or faults.

This alternator has amazing regulation. It produces constant voltage at loads from 0A to 500A.

The embedded control logic, communication and monitoring systems was developed and programmed in conjunction with the manufacturer – Milspec Manufacturing.

Key Monitor System

The key monitor system is a tracking system for keys. We have produced the electronic designs, PCB designs, and programming for this project.

The Key Monitor System uses a touch panel computer to allow a user to enter their UserID and password. The user can then access keys in the key rack. The keys “slugs” are inserted into the key locks in the panel, and can only be removed when released by the control computer.  If a key is not in the rack then the system can tell you who took the key and when they took it.

User access is controlled by time and date rules which govern key movements. Each user can have different security levels, and access to different keys. The system includes its own backup power supply, so it can operate without power for some time.

Alarms monitor key availability and are triggered by keys be out at the wrong times, or in at the wrong times, or out for too long. The system can be interfaced to an alarm system, and includes its own siren.

Key security levels are adjustable. Some keys need a password to be accessed, some keys need two users to authorise their use. The system can tell a user who currently has a key, and when they got it. Key slugs are unmarked, nickel plated metal slugs All activity is logged on the system, and remotely through a network to a logging server.

The Key Monitor Sytem can control one to four panels of keys. Each panel can be 18 or 54 keys.  Systems can be connected via data networks to share keys and users.
