Provided is a setting apparatus for remote monitoring and control system, which is capable of setting relational data and address simultaneously, and is hardly being lost. It includes a fixed part 1 fixed to an installation surface, and the portable part 2 detachably attached to the fixed part 1. When the portable part 2 is retained at the fixed part 1, the portable part 2 can be electrically connected to a signal line, and sets relational data for a transmission controller. When the portable part 2 is separated from the fixed part 1, the portable part 2 can set addresses corresponding to a switch and a load, with respect to an operation terminal and a control terminal, according to a signal as an infrared light transmitted from a light emitting element installed at the portable part 2. While the addresses are not being set, since the portable part 2 can be retained at the fixed part 1, the portable part 2 will not be easily lost although a dedicated storage receptacle is not installed.

The present invention relates to a grid system for supplying power to a black box for a vehicle by means of photovoltaic power generation, the grid system comprising: a solar cell unit for generating power by using photovoltaic power generation; a main system for supplying a black box with the power generated from the solar cell unit; and an internal battery for storing the power which is from the main system and generated by solar cell unit. Provided is the effectiveness in which, if photovoltaic power generation is not performed due to change in the amount of sunlight or a vehicle parking state, discharging of a battery inside a vehicle is prevented by enabling the supply of power first from an internal battery that stores the power from photovoltaic power generation.

The system is scientific and reasonable, predicts the destination of the user by analyzing the walking behavior of the user, whether the user goes to the courier station to take the online shopping goods or not is calculated according to the distance between the user and the courier station, logistics pickup information is automatically sent to a display screen of the mobile phone of the user, the user can directly take the goods through the pickup information displayed on the display screen, the pickup information does not need to be additionally checked, and more convenience and rapidness are achieved.

A fingerprint identification unlocking system comprises a key device and a lock device. The key device comprises a communication and electric power sending module, a fingerprint sensing module, and abattery. The fingerprint sensing module detects fingerprint input and generates fingerprint information based on the fingerprint input. The communication and electric power sending module outputs fingerprint information and electric power supply. The lock device comprises a communication and electric power receiving module, a storage module, and a processing module. The communication and electricpower receiving module receives fingerprint information and electric power supply from the key device and supplies the electric power supply to the storage module and the processing module. The storage module stores at least one verification information, and each verification information is corresponding to multiple characteristic points of a fingerprint. The processing module analyzes whether thefingerprint information comprises characteristic points of corresponding fingerprint, and the processing module executes unlocking if the result is positive.

The invention discloses an automatic control system for cognitive radio equipment. The automatic control system comprises a power supply used for providing the cognitive radio equipment with electricity, wherein the power supply comprises a storage battery, a switchgear, a charge device and a switching device; the switching device is used for driving the storage battery to move on the switchgear and the charge device back and forth; the switchgear is electrically connected with the external cognitive radio equipment; the charge device is electrically connected with an external power supply andthe switchgear; and a vacant position is arranged between the charge device and the switchgear. According to the automatic control system for the cognitive radio equipment, vacancy when the storage battery is not used can be achieved through the arrangement of the vacant position, and the problem that the service life of the storage battery is shortened due to too many charge cycles of the storage battery is solved.

A backup battery box for an electric cylinder is assembled with a control box and electrically connected to drive the electric cylinder, including: a charging and discharging device and a rechargeable battery. The charge and discharge device includes: a protection unit, a power conversion unit, a voltage detection unit, a control unit, a discharge unit, a display unit and a switch unit. The rechargeable battery is electrically connected with the charging and discharging device. When the start switch of the switch unit is pressed, the power of the rechargeable battery is transmitted to the control box by the charging and discharging device. When the power-off switch of the switch unit is pressed, the charging and discharging device is in a non-power supply mode, so that the power of the backup battery box is not exhausted.

Embodiments of the present invention provide a micro-bus operation management system and method. The micro-bus operation management system includes a server and a management terminal connected by mutual communication; the management terminal includes: a parameter receiving module for receiving input constraint parameters; a parameter sending module for sending the constraint parameters to the The server, the constraint parameters include a plurality of stations, vehicle driving time and charging time; the server includes: a rule calculation module, which is used to calculate and obtain according to the received driving time and charging time in the constraint parameters The first vehicle travel arrangement rule between each site in the constraint parameter; a rule sending module, configured to send the first vehicle travel arrangement rule to the management terminal, so that the staff corresponding to the management terminal can follow the The first vehicle travel arrangement regularly arranges departure.

When a mobile power supply charges a mobile electronic device through a charging transfer way, a detection and display method for mobile power supply charging information includes the steps: a data acquisition step comprising that according to a user choice, at least one group of mobile power supply parameter data and at least one group of machine parameter data are provided, and then the mobile power supply parameter data and the machine parameter data are respectively transmitted to an operation module of a processing unit of the mobile electronic device; an integration and operation step comprising that after the mobile power supply parameter data and the machine parameter data are integrated and operated by the operation module, charging information is generated; and an information output step comprising that the charging information is transmitted and outputted to an input and output device of the mobile electronic device. Therefore, the method can avoid the problem that a mobile phone and the mobile power source both have no electricity due to missing for charging the mobile power supply, and efficacies of significantly improving the product availability and use convenience can be achieved.
