A crane positioning system and positioning method. The invention adopts the industrial control computer as the core, organically integrates the industrial control computer, the data acquisition card, the lower computer PLC and the sensor, and fully exerts their respective advantages. On the basis of not affecting the design and control scheme of the original crane, the system uses high-precision laser sensors and encoders to measure the distances of the crane in the three directions of x, y, and z, and sends them to the industrial control through different types of data acquisition cards. In the computer CPU, at the same time, OPC technology is used to read the running status of the crane from the lower computer PLC to the upper computer-industrial control computer in real time through the field bus, and then use Visual Basic and other advanced languages ​​to write data processing and interface in the industrial control computer. The display program achieves the purpose of displaying the running position and status of the crane in real time, thereby providing the crane operator with accurate data on the operation of the crane, and at the same time providing a solid research foundation for the realization of high-precision unmanned driving of the crane.

The invention provides a water supply network simulation experiment platform which comprises a pipe network system, an on-line data acquisition system, and a monitoring control and management operation system. The pipe network system is provided with two water supply tanks, pressurization water pumps, water inlet points, dozens of control flaps, and sensors of on-line pressure transducers and on-line flow sensors. The on-line data acquisition system acquires signal information of the pressure transducers, flow sensors and the like. The monitoring control and management operation system can realize control of stepless frequency conversion of two water pumps in a pipe network and display data acquired by the on-line data acquisition system in real time in forms of a number and a curve.

The invention relates to an on-line monitoring system of a milking pulsator for cows. The on-line monitoring system comprises a vacuum pressure sensor, wherein the vacuum pressure sensor is connected with a pulsation pipe of the pulsator and used for detecting change of vacuum pressure in the pulsation pipe; the vacuum pressure sensor is also connected with a single-chip microcomputer control circuit, and the single-chip microcomputer control circuit is used for controlling the acquisition frequency of the vacuum pressure sensor and uploading data acquired by the vacuum pressure sensor to an upper computer; the upper computer draws a pulsator running curve according to the received pulsation frequency, pulsation rate and vacuum fluctuation and judges whether the pulsator is normal or not according to the drawn curve. The system can display all milking positions and the running state of the milking pulsator in real time and can give alarms timely for the abnormal pulsator or the air leaking position of a milking pipeline.

The invention provides an intelligent remote wireless meter reading and billing system which comprises an intelligent electric meter, a data acquisition unit, a coordinator and a management system.The coordinator creates a wireless network with independent network identification.The data acquisition unit joins the network.The intelligent electric meter encrypts power utilization information and generates a network address containing the data acquisition unit, identification information and a power utilization information frame of the encrypted power utilization information are uploaded to the data acquisition unit, the data acquisition unit detects the sub-channel state, if a sub-channel is in a busy state, the data acquisition unit enters a sending delay state and continues to carry out detection, and if the sub-channel is in an idle state, the data acquisition unit sends a data sending request to the coordinator and sends the power utilization information frame after receiving data sending allowing information returned by the coordinator.When the coordinator receives the power utilization frame and judges arrival of sending slot time, the coordinator sends the power utilization frame to the management system, the management system decrypts the power utilization information, displays the power utilization information in real time, calculates electric charge and sends short messages containing electric charge information to users.
