Bluetooth remote control parking space lock-based parking reservation fee collection system and method thereof

InactiveCN105513412AComplete closed-loop reserved parkingComplete closed-loop charging processTicket-issuing apparatusReservationsCollection systemApplication software
The invention discloses a Bluetooth remote control parking space lock-based parking reservation fee collection system and a method thereof. The parking reservation fee collection system includes Bluetooth remote control parking space locks installed on parking spaces, an application module (APP) applied to a mobile communication terminal, and a cloud service platform applied to the server. The Bluetooth remote control parking locks can send keys through mobile phone Bluetooth communication to achieve lock lifting and lock descending functions. In the application module (APP), the specific locations of reservable parking spaces can be displayed through a map or a drawing of the interior of a parking lot; unoccupied parking spaces can be reserved online through the APP; unlocking keys sent by the cloud services platform can be received through the APP, so that lifting and descending operation can be performed on the parking space locks; and the payment of parking fees can be completed through mobile phone mobile payment. In the cloud service platform, user registration and login services are provided according to the APP; parking space information reservation services are provided for the APP; parking space states in a database are updated; the equipment numbers and unlocking keys of parking space locks of parking spaces which are successfully reserved are transmitted to the APP; parking duration and cost are calculated; and the parking space states are updated. The invention also discloses a parking reservation fee collection method of the parking reservation fee collection system.

Bioremediation method for soil polluted by heavy metals

ActiveCN102553904AComposite treatment effect is goodConsiderable enrichmentContaminated soil reclamationMicroorganismPollution soil
The invention discloses a bioremediation method for soil polluted by heavy metals. The bioremediation method comprises the following steps of: adding earthworm feeds into the soil polluted by the heavy metals, turning the soil, uniformly mixing, and putting earthworms into the soil and cultivating the earthworms; after the earthworms are cultivated for 28 to 35 days, collecting earthworm excrements in the upper layer soil, collecting adult earthworms by adopting a natural lighting method, and retaining young earthworms and earthworm eggs in the soil; planting plants by adopting a hedge planting method, cradling the parts of the plants growing for 78 to 90 days, which are positioned above the ground, and removing the whole plants after the plants grow for another 50 to 70 days; collecting the adult earthworms and the earthworm excrements for 1 to 3 days by adopting an outdoor collection method every 28 to 35 days during planting of the plants; and after the whole plants are removed, collecting all the adult earthworms and the young earthworms by adopting the natural lighting method, and collecting the earthworm excrements and the earthworm eggs. The soil is subjected to remediationby combining animals, plants and microorganisms according to a proper remediation sequence and a remediation period, so that the bioremediation method is economic, environment-friendly, easy to operate, high in remediation efficiency and easy to popularize, and is particularly suitable for mild or moderate copper, cadmium and lead combined polluted soils.

Fingerprint collection system and fingerprint information collection method

The invention relates to a fingerprint collection system comprising a fingerprint sensor, a scanning controller, a sensing unit driving circuit, an image output unit and a mode control circuit. The fingerprint sensor comprises a fingerprint sensing unit array, an antenna metal frame and a radiofrequency driving circuit; the fingerprint sensing unit array includes multiple sensing units, and the radiofrequency driving circuit drives the antenna metal frame to transmit radiofrequency signals. The scanning controller is used for selecting at least part of the sensing units of the fingerprint sensing unit array to serve as effective sensing units for sensing fingerprints and converting the same into electric signals. The sensing unit driving circuit is used for providing time-sequence signals needed for work of the effective sensing units. The image output unit is used for converting electric signals into digital fingerprint image information and outputting the information. The mode control circuit is used for controlling the sensing unit driving circuit to send different time-sequence signals to change working modes of the fingerprint collection system. The working modes at least include a capacitive collection mode and a radiofrequency collection mode. The fingerprint collection system has wide application range and has good collection and recognition effects in various application fields.
