The invention relates to a battery pack frame, which comprises a movable plug-in type frame body used for the placing of battery modules, wherein the movable plug-in type frame body is mainly formed by splicing a plurality of linear cross beams, linear longitudinal beams and liner vertical beams through corner connecting pieces. According to the scheme provided by the invention, the linear cross beams, the linear longitudinal beams and the liner vertical beams are plugged in and spliced to form the movable plug-in type frame body, and according to the required size dimension of the battery frame, the linear cross beams, the linear longitudinal beams and the liner vertical beams with different length dimensions are selected and are then spliced and fixed through the corner connecting pieces, so that a battery pack has extensibility, the development of a mold is reduced, and the installation dimension requirements of different vehicle models are met; in addition, the battery pack frame is convenient to install and disassemble, and the economic benefit of the battery pack frame is improved.

The invention relates to a two-dimensional layered perovskite layer and a preparation method thereof. The preparation method mainly comprises the following steps: uniformly mixing a certain amount ofbutylamine hydroiodate or butylamine hydroiodate and methyl ammonium iodide with a certain amount of lead iodide so as to obtain mixed powder; transferring the mixed powder into a polytetrafluoroethylene liner, and performing sealing; putting the sealed polytetrafluoroethylene liner into a reaction kettle, and performing heating for 24-48 hours at 160-200 DEG C, so as to obtain the two-dimensionallayered perovskite crystal (BA)2(CH3NH3)n-1PbnI3n+1, wherein n is a positive integer. By adopting the method, a toxic solution is not adopted for the reaction, so that the method is green and environment-friendly. In addition, the two-dimensional layered perovskite crystal prepared by using the method is good in stability.

The invention provides a shallow water wave-following scanning detection system based on a single beam and a working method thereof. The shallow water wave-following scanning detection system comprises an overwater wave-following scanning detection terminal and a remote control terminal. The overwater wave-following scanning detection terminal achieves overwater detection work and data transmission work. The remote control terminal achieves a data processing function and a remote control function. The overwater wave-following scanning detection terminal and the remote control terminal achievereal-time interaction through network transmission. The system can detect a plurality of water depth points deviating from the position under a ship by a certain distance under wave swing, and accordingly, the detection range is enlarged so as to achieve the wave-following scanning detection effect and improve the detecting efficiency. The system conducts depth correction and coordinate correctionunder the wave effect by detecting the inclination angle of the detection ship relative to the water level, and thus accurate detection data of real detection points are obtained. The transmitting velocity of transmitting signals is adaptively adjusted according to the wave size and the detected water depth. The shallow water wave-following scanning detection system utilizes the wave effect to enlarge the detection range and has the advantages of being simple, efficient, economic and applicable.

The invention relates to an automobile driver and passenger monitoring system. The automobile driver and passenger monitoring system comprises an infrared camera, millimeter wave radar sensors, an ECUcontroller, a display and an alarm, wherein the ECU controller is connected with the infrared camera, the millimeter wave radar sensors, the display and the alarm; the infrared camera is arranged onthe front side of a driver seat; and the millimeter wave radar sensors are arranged above the front of each seat. Compared with the prior art, the automobile driver and passenger monitoring system hasthe advantages that legacy monitoring and health condition monitoring can be achieved at the same time through the millimeter wave radar sensors, the complexity of an existing monitoring system is greatly simplified, high accuracy is achieved, and non-contact detection can further bring good user experience.

The invention discloses an AGV scheduling method realized through uploading a task file. The method comprises the following steps that 1) RFID tags are embedded in all the nodes of a magnetic navigation track and all the node where an AGV may stay or carries out task operation; and 2) an upper computer scheduling system processes a selected task route and a set parameter into a task file, through a wireless communication mode, the task file is uploaded to the AGV, and the AGV receives and reads the task file, determines whether a position where the AGV itself is located is correct according to a parameter set in the task file and executes an assigned task. The parameter comprises an RFID number of a point where the AGV is located, waiting time at an assigned point, an activity performed at the assigned point, selection to a branch at an assigned node and the like. In the invention, AGV control does not depend on a landmark, a base station or a graphic identification; task details are stored as a file form so that one or the plurality of AGVs are effectively scheduled at different time periods; and the method is flexible and applicable, and cost is saved.

The embodiment of the invention relates to a terminal test method, a terminal and a readable storage medium, and the terminal test method comprises the steps: receiving an Android test bridge instruction for testing, the Android test bridge instruction carrying an instruction value for indicating a to-be-tested function; obtaining an instruction function corresponding to the instruction value carried by the Android test bridge instruction according to a preset corresponding relationship between the instruction value and the instruction function; and calling an instruction function to test theto-be-tested function. Through the calling mode, the terminal can use the called function to test the to-be-tested function indicated by the instruction value when processing the Android test bridge instruction, cross-platform and normalized testing is achieved, and therefore the testing efficiency is improved.
