Transmission system and coding communication method for a transmission system

A communication coding method for a transmission system for use with a mobile unit along a predetermined route the method comprising the steps of:

• a) detecting if the mobile unit is moving along said predetermined route,
• b) receiving an input signal containing information asynchronously or synchronously in accordance with a predetermined radio scheme using receiving means contained in one of a plurality of modules installed at different positions along the predetermined route, and
• C) transmitting an output signal containing at least a portion of the information contained in said signal through two or more of the plurality of modules along at least a portion of said predetermined route asynchronously or synchronously using transmission means contained in the two or more modules in accordance with the predetermined radio scheme;
• wherein each of the plurality of modules includes at least one of (i) a weight measuring section for measuring weight of the mobile unit moving along said predetermined route, (ii) a magnetic field generating section for generating a magnetic field along said predetermined route, or (iii) a laser radiation section for transmitting a laser beam toward the mobile unit moving along said predetermined route.

In a transmission system having a plurality of modules installed at different positions along a predetermined route, a method of communicating a presence of a mobile unit moving along the predetermined route comprising the steps of:

• (a) receiving in a respective one of the plurality of modules a first input signal containing first information from another module installed along the route;
• (b) receiving in the respective one of the modules a second input signal containing second information from a mobile unit moving along the route;
• and
• (c) receiving in the respective one of the modules a third input signal containing third information indicating the presence of the mobile unit moving along the route, the third input signal separate and independent from the first and second input signals and the third information separate and independent from the first and second information;
• wherein the respective one of the modules includes at least one of (i) a weight measuring section for measuring weight of the mobile unit moving along said predetermined route, (ii) a magnetic field generating section for generating a magnetic field along said predetermined route, or (iii) a laser radiation section for transmitting a laser beam toward the mobile unit moving along said predetermined route.

A transmission system for use with a mobile unit along a predetermined route, comprising:

• a plurality of modules installed at different positions along the predetermined route, each of the plurality of modules includes
• i) receiving means of receiving an input signal containing information,
• ii) transmission means of transmitting an output signal based on said input signal in accordance with a predetermined radio scheme,
• iii) mobile unit detection means of detecting the presence of the mobile unit along said predetermined route;
• wherein said output signal from each of the plurality of modules contains at least a portion of the information contained in said input signal and said output signal is transmitted along at least a portion of said predetermined route through two or more of the plurality of modules;
• wherein each of the mobile units have a length and wherein said plurality of modules are spaced such that the distance between adjacent modules is less than the length of each of the mobile units.

A transmission system for use with a mobile unit along a predetermined route, comprising:

• a plurality of modules installed at different positions along the predetermined route, each of the plurality of modules includes
• i) receiving means of receiving an input signal containing information,
• ii) transmission means of transmitting an output signal based on said input signal in accordance with a predetermined radio scheme,
• iii) mobile unit detection means of detecting the presence of the mobile unit alone said predetermined route;
• wherein said output signal from each of the plurality of modules contains at least a portion of the information contained in said input signal and said output signal is transmitted along at least a portion of said predetermined route through two or more of the plurality of modules;
• wherein a minimum following distance is established for mobile units along the predetermined route and wherein the plurality of modules are spaced such that adjacent modules are separated by less than the minimum following distance.
