Toll road charge collection system using artificial satellite, charge collecting machine, and charge collecting method

A toll road charge collection system comprises a vehicle (7) having an on-vehicle machine (11, 130) mounted thereon, an artificial satellite (1), and a system data center (20). The on-vehicle machine (11, 130) receives radio signal from the artificial satellite (1), and calculates the latitude, the longitude, and the altitude as the vehicle position according to the received radio signal. Latitude data, longitude data, and altitude data indicating the traveling vehicle position history are stored in an external storage unit (46) as a time-series log file, and transmitted to the system data center (20), where the data are stored/accumulated in a storage unit (63) for each vehicle. In the system data center (20), a toll road section in which the vehicle (7) has traveled is determined according to the toll road path position data including the latitude data, the longitude data, and the altitude data indicating the traveling vehicle position history transmitted from the vehicle (7) and stored/accumulated in a database. The traveling charge is calculated for each person traveling on the toll road according to the traveling charge data specified for each route section, and the charge is collected by the automatic payment through an account of a financial institution (25) set by the toll road traveling person in advance.

A laser radar imaging device based on compressed sensing and an imaging method are disclosed. The device comprises an amplitude modulation laser light source, a beam expanding apparatus, two lenses, a DMD digital micro-mirror, an APD photoelectric detector, a high-pass filter, a multiplier, a low pass filter, two AD analog-digital converters, a control system and an image reconstruction system. After being emitted, the laser is scattered by an imaging object and then is projected to a surface of the DMD digital micro-mirror. Reflected light is focused by another lens, then is received by an APD single point detector and then is converted into an amplified voltage signal. High-pass filtering, mixing and low-pass filtering are successively performed on the voltage signal on one parallel branch and the signal penetrates into the reconstruction system after analog-digital conversion. Simultaneously, the voltage signal directly penetrates into the reconstruction system on another parallel branch after the analog-digital conversion. According to input signals of the two branches and a random matrix corresponding to a DMD control device, a certain reconstruction algorithm is combined so that the reconstruction system can complete imaging. By using the device and the method of the invention, an imaging rate and imaging quality are increased to a great extent.

Method for deleting wireless link under out-of-step state

The invention relates to a method for deleting the wireless chain circuit in out-of step condition, which comprises: when the user terminal (UE) receives the RRC connection release message sent from the network, and the responding to said RRC connection release message to the network, if the UE detects that it is out-of-step, directly releasing the chain circuit between it and network and deleting all local resource relative to said chain circuit; when the network UE sends RRC connection release message, and there is no RRC connection release complete message received in some time, responded by said UE, and if the network detects the chain circuit of said UE is out-of-step, directly releasing the network resource occupied by said chain circuit; when the network receives the region refresh message about RL chain circuit failure sent by UE at the second region, and assuring that said UE is in the RRC connection release process in the first region, the network uses the second region to send RRC connection release message to UE; and after said UE receives the RRC connection release message, it releases the chain circuit between it and networks, and deleting all local resource relative to the chain circuit. The invention can reduce the electricity consumption of terminal, and reduce the signal interference on other users.

Control method for outdoor direct current fan of variable frequency air conditioner

The invention relates to control technologies of variable frequency air conditioners, discloses a control method for an outdoor direct current fan of the variable frequency air conditioner, and solves the problem that in traditional technologies, the revolving speed of the outdoor direct current fan of the variable frequency air conditioner cannot be matched with a system optimally, and as a result, the capacity and the reliability of the system are influenced. The method comprises the steps that the original revolving speed of the direct current fan is determined according to the frequency of a compressor and the outdoor environment temperature; in the running process of the compressor, the revolving speed of the direct current fan is adjusted in real time according to current system parameters, such as the outdoor coil temperature, the IPM temperature, the exhaust temperature and the environment temperature, and the stepless speed regulation function of the fan revolving speed is achieved; and after the compressor is stopped, the outdoor coil temperature and the IPM temperature are detected, whether the fan runs or not, the running speed of the fan and the running time of the fan are determined according to the temperatures. According to the control method, compared with an original control scheme in which the fan is stopped when the compressor is stopped, the temperature of the corresponding system can be reduced rapidly, the method is beneficial to shortening the time of system recovery due to the fact that the overheated system results in shut down of the compressor, and the time interval of once again start of the compressor is shortened.
