The invention discloses a method for testing machine tool hydrostatic guideway surface shape error, and the method comprises the following steps: (1) the number of test sampling points on a hydrostatic guideway guide surface is planned; (2) a laser interferometer is arranged on the surface of a workbench and is used for measuring a pitch angle of the workbench; (3) two displacement sensors are arranged on the workbench and are used for measuring hydrostatic guideway surface variation based on the workbench; (4) according to the distance of each step in a recursion test, to-be-tested parts on the hydrostatic guideway guide surface are equally divided and marked; (5) the measurement starts, one step distance runs once from zero position, step distances connect end to end, and readings of the laser interferometer and the displacement sensor are recorded; and (6) a shape error of the hydrostatic guideway guide surface is obtained through data analyzing and processing. According to the invention, the measurement of machine tool hydrostatic guideway guide surface shape error can be directly completed through cooperation of the laser interferometer and the displacement sensor.

The invention provides a quick-response linked target system and relates to a KL-II type quick-response linked target system, belonging to shooting practice equipment characterized by pure mechanical linked action. Targets in the system can be used for separate shooting practice and linked shooting practice, namely precision shooting practice and quick linked shooting practice; and the accurate judgment capability and quick-response capability of trainers can be improved during practice. Moreover, the system has a better ornamental value and is suitable for various exercises and performance occasions. The system comprises an up / down type steel plate head target, a short-distance running target, a swing target, a quick double-click target and a trigger mechanism. The system is of a pure mechanical structure; and when the system is in a linked state, all the targets share the same trigger mechanism; except that the up / down steel plate head target serves as the first target, the short-distance running target, the swing target and the quick double-click target can be used as different modules; and according to the shooting demands, the positions and triggering sequences of all the targets can be combined at random or each target can be regarded as an independent unit and separated from the system to be used for separate specialized training.

The invention provides a charging planning method for long-distance operation of electric vehicles in intelligent transportation. Includes path finding and charging schemes. In the path finding, the starting point, destination point and charging station are regarded as all passing points in the path, and a two-stage search is adopted to extract all possible paths and give a plan to reach the destination. After the route is given, the charging time and travel time of each route are calculated. In the charging scheme, the number of vehicles waiting for each charging station, the estimated queuing time and the new queuing time when the electric vehicle arrives at the charging station are estimated through queuing theory, and the queuing time at the accessible charging station is estimated, and it is combined with the search path The charging time and travel time are obtained by merging the time in the vehicle, and a reasonable route is planned by the coordination curve method. The present invention can provide optimal route selection when there is no charging demand, and can also provide a route selection scheme and a charging planning scheme when there is a charging demand.

The invention relates to the technical field of motor skill evaluation, in particular to a student football skill grade evaluation system, including a shooting evaluation unit, a ball-fixing evaluation unit, sprint evaluation unit, a long-distance running evaluation unit, a data transmission module and a computer, wherein the shooting evaluation unit includes a goal detection module, goal sensingdevice, a goal counting module and a goal counting device; the ball-receiving and ball-fixing evaluation unit comprise a monitoring module, the sprint evaluation unit comprises a speed detection module, a speed sensor, a time detection module and a timer. The long-distance running evaluation unit comprises a heartbeat detection module and a heartbeat detector. The computer comprises a central processor, a storage module, a database, a data analysis module and a class classification module. The advantage of the invention is that each ability of the athlete can be judged reasonably, and then thegrade is judged according to the comprehensive ability.

The invention belongs to the technical field of physical fitness testing, and in particular is an automatic middle-distance running tester for sports. The right end face is fixed with a second cabinet set in a concave structure, and the second cabinet communicates with the first cabinet; when using this device, the staff first moves the push base to the designated position, and then fixes the universal wheels. Prevent the movement of the universal wheel and drive the base to move, and then the staff can adjust the height of the monitoring equipment according to their own height. At this time, the motor needs to be energized, and then the main shaft of the motor drives the gear to rotate, and then the rack moves upward to make the monitoring equipment The equipment is also moving upwards, so that it is convenient to adjust the height of the monitoring equipment according to the height of the staff, so as to prevent the lumbar spine from being damaged due to heavy workload and long-term bending when the body is sideways.

The invention proposes a method and device for generating a movement authorization of a train, an ATP and a ZC. Among them, the method includes: obtaining the first distance between the preceding vehicle and the following vehicle, obtaining the reaction time required for the following vehicle to run the first distance according to the speed information of the following vehicle, and obtaining the distance of the preceding vehicle according to the speed information of the preceding vehicle. The second distance traveled within the reaction time generates a movement authorization for the following vehicle according to the first distance, the second distance and a preset safety margin. In the present invention, when calculating the movement authorization of the rear vehicle, the actual motion state of the vehicle in front is considered, and the vehicle in front is no longer set as a static obstacle, which can make the movement authorization longer, thereby reducing the tracking distance and improving the accuracy of the route. Operational efficiency can increase the departure density during the peak period of operation and reduce the operating pressure during the peak period.

A support system of an engineering machinery and the engineering machinery having the support system. The support system comprises a first support leg (21), a second support leg (22), a third support leg (23), and a fourth support leg (24) arranged on the engineering machinery, and additional support legs (25 and 26) arranged between the third support leg (23) and the fourth support leg (24). The minimum distance running from support points of the third support leg (23) and of the fourth support leg (24) to the circumference of a circle around the center of gravity of the engineering machinery is less than the minimal distance running from the support points of two adjacent support legs among the third support leg (23), the fourth leg (24), and the additional support legs (25 and 26) to the circumference of the circle around the center of gravity of the engineering machinery. The arrangement of the additional support legs (25 and 26) increases the anti-rollover capability and support capability of the entire vehicle, while at the same time, when the lengths of the support legs are reduced, obviates the need to occupy a great area of a site, and maintains a degree of stability identical to existing support systems, thus allowing the engineering machinery having the support system to be applicable in limited spaces, and satisfying construction needs on sites that are narrow and small.
