ABSTRACT:
By this invention a system for controlling the servicing of customers arriving in a vehicle at a service area is provided, in which system the arrival of the vehicle, the supplying of the services and the departure of the vehicle is monitored. The system includes a number of signals which keep the attendants in or near the service area fully informed as to the status of the operations that are going on relative to a given vehicle. Thus, the arrival of the vehicle is announced and that arrival sets into operation a control means which is responsive to an unauthorized departure of the vehicle. In other words, if a vehicle attempts to leave the service area before the service is completed or before the services have been paid for, an alarm is activated by the control means announcing the impending unauthorized departure. Present also in the system is a means for preventing any of the signals from functioning in the absence of a vehicle that has come into the service area for service. Also present is a means for announcing the proper completion and authorized departure of a given vehicle from a given service area. The various steps involved in a given service that is being offered are programmed and the system includes a means for preventing the actuating of any given alarm other than in its programmed sequence.
The system provided by this invention includes the monitoring of several different service areas. Electrical circuitry is involved with respect to each of the given service areas so that the control information is fed from the given service area independently of events that are happening in any other service area, but all of the electrical circuitry relative to the various service areas are powered from the same power source. Thus, this invention comprises the processes involved for effecting the monitoring, the overall system, and the electrical circuitry involved, all of which appear hereinafter.
