Planning the System


This chapter deals with all aspects of planning and laying out the system ensuring that when the next level is approached ("Building the system"), all the modules should slot into place without a hitch. This section is entirely 'paper' and if done correctly could be used to order the required equipment already preprogrammed for use in the various sites (note: some suppliers will charge to preprogram units to be "ready for use").

"Achieving the requirements" ensures the system has been correctly defined and all signals that need relaying are properly documented. Non or ill identification of a signal could result in the incorrect equipment being ordered resulting in financial constraints being placed on the project. Sample Excel files to assist with planning have been included in this section.

"Catering for expansion" deals with the oldest of human problems, the 'need' to want more! Now that you are building a system that is going to work someone, somewhere, once they see just how reliable radio telemetry is, will want more signals relayed from one point to another - this needs to be catered for at this stage of the cycle.

"Supplying the power" deals mainly with alternative power sources as it is assumed that when mains power is available there will be little, if any, power constraints. Errors made during this phase of the planning is what has resulted in the failure of many systems and costly returns to site to try and rectify the problem.

"Healthy Comms" deals with ensuring the data gets through by ensuring the antennas are specified correctly. Also covered is the planning the data rate such that the data is sufficiently up-to-date while avoiding 'radio overload' which could bring a system to a standstill (often as a result of an overeager process engineer wanting the results "as immediate as possible").
