Automatic non-computer network no-stop collection of expressway tolls by prepaid cards and method: pay according to category of vehicle and the distance it travels

An automatic non-computer network system for toll collection from a vehicle moving along an expressway, according to a category said vehicle belongs to and a distance said vehicle travels, using infrared signals as communicating means between devices at toll booths one at an entrance and another at an exit of said expressway and a device in said moving vehicle and as means to calculate toll and differentiate vehicle comprises:

• a toll booth at each entrance;
• a toll booth at each exit;
• and
• an in-vehicle unit to be installed in said vehicle;
• wherein first toll booth which is at each entrance of said expressway has a toll-collecting device comprises first support booth and first main booth located at fixed positions apart relatively on said expressway, and first central processing unit (CPU) installed at a relatively fixed position at said first main booth which connected to all other components of said toll booth for controlling functions of all components both at said support booth and at said main booth where
• said first support booth of said entrance has a booth canopy and all its components positioned at fixed positions relatively at said booth canopy, comprising:
• first red light bulb;
• first green light bulb;
• first voice alarm which can be actuated to give an audible signal, together with a blue light bulb connected thereto;
• first camera;
• first light-emitting diode (LED) which emits an infrared beam of switch on tailing-up type, where said infrared beam can detect the passage of all vehicles of any different heights equal to or greater than 0.50 meter passing through said first support booth;
• second LED, which emits an infrared beam of switch on tailing-down type, positioned relatively rearward to said first LED emitting said infrared beam of switch on tailing-up type from the point said vehicle entering said first support booth, where said infrared beam can detect the passage of all vehicles of any different heights equal to or greater than 0.50 meter passing through said first support booth;
• said first main booth of said entrance has a booth canopy and all its components positioned at fixed positions relatively at said booth canopy, comprising:
• first comparator;
• first infrared signal receiver connected thereto said first comparator to receive an infrared signal of a modulation frequency identifying said vehicle transmitted from a transmitter of said in-vehicle unit installed in said vehicle;
• first transmitter, transmitting an infrared beam of a predetermined modulation frequency identifying each particular entrance out at an inclination angle towards said first support booth at all time by command from said first CPU;
• third LED emitting an infrared beam of switch on tailing-up type, where said infrared beam can detect the passage of all vehicles of any different heights equal to or greater than 0.50 meter passing through said first main booth;
• fourth LED emitting an infrared beam of switch on tailing-up type, where said infrared beam can detect the passage of all vehicles of any heights equal to or greater than 2.0 meters passing through said first main booth but not those of heights less than 2.0 meters;
• fifth LED emitting an infrared beam of switch on tailing-up type, where said infrared beam can detect the passage of all vehicles of any heights equal to or greater than 2.80 meters but not those of heights less than 2.80 meters passing through said first main booth;
• sixth LED, emitting an infrared beam of switch on tailing-down type, positioned relatively rearward to said three LEDs emitting said infrared beam of switch on tailing-up type from the point said vehicle entering said first main booth, where said infrared beam can detect the passage of all vehicles of any different heights equal to or greater than 0.50 meter passing through said first main booth;
• second voice alarm, which can be actuated to give a siren audible signal, with an orange light bulb connected thereto;
• and
• second camera.
