DETAILED DESCRIPTION OF THE INVENTION
Traditional street parking meters are in the process of being phased out and replaced by meters that are enabled to accept modern methods of payments, e.g., credit cards, debit cards, smart cards, pay-by-phone, etc. Replacement and installation of an entirely new unit is costly for cities, municipalities, or other authorities in charge of street parking meters, thereby causing eventual increase in parking rates to recover the cost of purchase and installation. Moreover, replacement and installation of an entirely new unit creates electronic waste. The cover housing described in the present invention, offers a cost effective and environmentally-friendly solution to the problem. The cover housing of the present invention can be easily fitted to existing street parking meters, even those that have previously been upgraded by replacing the internal meter mechanism. These replacements further allow for sensor replacement, upgrades, or additions. Installations of sensors in existing street meters typically involve excessive road work, drilling, and infrastructure modifications on street lights, utility poles, and underground wiring. The replacement, upgrade, or addition of sensors using a replacement cover housing or an upgrade to a cover housing reduces waste, is easier to install, and is cheaper to maintain.
In certain embodiments, the cover housing of the present invention is completely solar powered. Street parking meters that are upgraded using a solar powered cover housing described herein do not need batteries to operate. This feature further reduces the operating cost of the street parking meters that are upgraded with cover housing described herein. In other embodiments, the dome sensor is completely battery powered, completely wire powered, and/or optionally solar powered.
In certain embodiments, the cover housing of the present invention is equipped with one or more sensors, for detection of vehicles within the local environment of the parking meter on which the housing is deployed, and a wireless radio transmitter to communicate, directly or indirectly, with a remote management or maintenance server. In certain embodiments, the cover housing is also equipped with a RF tag reader. The RF tag reader can be used to read a wireless RF tag located on the base of an existing parking meter, and acquire information regarding the local environment.

In other embodiments, the cover housing does not include an RFID reader, but rather the electronic components of the cover housing communicate via wired or wireless connection to the meter device which does include an RFID reader. In such embodiments, the RFID reader of the meter device reads an RFID tag associated with the meter to obtain a unique ID, which is associated with a unique physical location in a remote database, and passes that information on to the cover housing.
In further embodiments, the meter device, including an RFID reader, will read an RFID tag associated with the meter to obtain a unique ID and use the ID to determine if the meter location is configured in the database to have a sensor. In further embodiments, if the meter location is configured in the database to have a sensor, the meter device downloads from a remote management system a binding code enabling the meter to wirelessly connect to, and wirelessly communicate with that sensor. This enables the meter mechanism to be changed and update automatically to communicate wirelessly with the sensor in place.
In some embodiments, sensor configurable parameters, testing, and feedback information are optionally displayed on the meter display or on a wireless handheld device of a user (smart phone, smart watch, etc.). The parameters, testing, and feedback information is useful used during initial setup and diagnostics. In fact, when the sensor detects a vehicle, in some embodiments, the sensor triggers an icon or other visual indicator to appear on the meter display in order to confirm that it is detecting properly.

In some embodiments, this event information is used to power-up the payment accepting unit (which had been powered-down to conserve energy), activate the payment accepting unit, or allow the payment accepting unit to anticipate or prepare for acceptance of payment.
In certain embodiments, the power unit affixed to the cover housing can be in an off-mode in the absence of any vehicle movement in the parking spots to the left or right of the meter. The power unit can be turned on, only upon detection, by the sensor affixed to the meter cover, of vehicle movement in the parking spots to the left or right of the meter. This results in reduction of energy costs associated with operating the meter. In certain embodiments, the meters rapidly switch on upon detection of vehicle movement, by the sensors, and are ready for carrying out payment transactions, through the user interface side, even before the vehicle driver walks up to the meter.
In some embodiments, the sensor affixed to the cover housing of the parking meter, communicates the information regarding the departure of the vehicle to the meter and this results in immediate resetting of paid time. In further embodiments, the sensor affixed to the cover housing of the parking meter, communicates through wireless radio, which in turn transmits the information to the wireless tag affixed to the parking meter, and this results in the update of the display screen. Thus, the parking meters describe herein is optionally used to avoid overlap of paid time between successive vehicles occupying the same parking spot. This enables collection of increased and accurate revenue from the parking meters of the present invention.
In certain embodiments, the vehicle movement information, within the parking spots to the left and right of the parking meter, can be collected by the sensor and transmitted, via the wireless radio transmitter (along with location identification information stored in an RF tag associated with the parking meter), to one or more remote servers, a cluster of servers, or cloud computing system. The types of information transmitted to the server can include, for example, average length of time during which the parking spots are occupied and paid for, average length of time during which the parking spots are unoccupied and not paid for, days of the week with maximum occupancy and/or vehicle movement in the parking spots, or times of the day with maximum occupancy and/or vehicle movement in the parking spots. The information stored at the server is optionally utilized to model the vehicle flux trends within the local environment of the parking meter, and fix parking rates and/or time limits for parking to precisely meet the needs of the local environment.
EXAMPLES
The following illustrative examples are representative of embodiments of the software applications, systems, and methods described herein and are not meant to be limiting in any way.
Example 1
Installing the Cover Housing
A city maintenance technician performs his duties, which include driving around town upgrading parking meters. He loads his vehicle with upgraded cover housings and a toolbox. When he approaches an outdated meter, he does not need to perform any major upgrades to infrastructure, such as drilling, underground wiring, road work, and the like. As such, he does not have need of any advanced or heavy tools, such as an industrial hammer drill. Instead, the technician uses his simple tools, for instance a screwdriver and a wrench, to disengage and remove the old cover housing from the meter. He then, using the same tools for removing the old housing, replaces and engages the new upgraded cover housing. The entire process for replacing the cover housing requires less than 10 minutes for completion. The technician returns the old cover housings to the manufacturer, whereby the cover housings are upgraded to incorporate new features.
Example 2
Installing Only a Portion of the Cover Housing
Technician from Example 1 is performing the same duties, except this time he is only replacing a portion of the cover housing. The portion of the cover housing contains upgraded parts beyond those provided in the upgraded cover housing detailed in Example 1, including upgraded sensors, an RFID tag reader, a self-contained power supply, and a dedicated wireless radio. The self-sufficient portion of the cover housing is installed onto pre-upgraded cover housings. The technician, using the same simple tools, such as a screwdriver and a wrench, disengages and removes a portion of the upgraded cover housing and then replaces and engages the upgraded portion of the cover housing, thereby completing an upgrade of an upgrade. The technician does not need to remove the entire cover housing to complete the upgrade, and thereby he does not need to tamper with the parts attached to the cover housing itself. The process for upgrading the upgraded cover housings similarly takes less than 10 minutes.
Example 3
RFID Start-Up Procedures
After technician upgrades a meter with an upgraded cover housing or an upgraded portion for an already upgraded cover housing, technician restarts the meter. The upgraded components scan the meter RFID tag and determine if that meter location is configured to have a sensor. If the meter is configured to have a sensor in that location, the upgraded cover housing or the upgraded portion will use either the meter's wireless radio or its own dedicated wireless radio to download a binding code from a remote management system. The binding code configures the meter, upgraded components, and sensors. The meter wirelessly connects to the new sensors. The meter display is reset, updated, and refreshed. The new meter is now ready for use.
Example 4
Environmental Pollution Sensor Network Through Parking Meters
Some upgraded cover housings or upgraded portions of cover housings contain various sensors capable of collecting environmental information. Technician upgrades meters around the city with sensors capable of detecting pollution, for instance carbon monoxide and carbon dioxide. The upgraded parking meters configure themselves as described in Example 3, and the meters begin to collect pollution information. The meters transmit this data to a remote server, which upgrades the database with the pollution information. Because meters throughout the entire city were upgraded with pollution sensors, the remote server database builds a pollution map of the city.
Example 5
Waking a Meter from Power Saving Mode and Priming Payment Methods
After a preset idle time, a parking meter enters a power saving mode. A car pulls into a parking spot managed by the parking meter. The sensors of the meter detect the presence of a vehicle and wake the meter from power saving mode to restore full functionality. The meter wirelessly retrieves a binding code and activates an integrated wireless payment receiver. The payment receiver is configured to accept payment through a variety of sources, for instance Apple Pay®, and is primed when the meter detects the presence of a newly-parked vehicle. The display screen is also updated upon retrieval of the binding code, allowing a user to easily pay after parking the vehicle.
Example 6
Meter Communication with City Personnel
A parking enforcement officer patrols the city hoping to hand out parking citations to meet her monthly quota. She carries a personal meter scanning device. As she approaches a parking meter, the meter's sensors detect the scanning device, and wirelessly connect to the remote management system to configure the meter to wirelessly transmit environmental information to the scanning device. The officer receives relevant environmental information in assisting her to issue parking citations, including meter identification, meter location, vehicle identification, license plate information, vehicle registration information, citation history, data indicating issuance of a citation, and data related to the type of citation issued.
