The invention discloses a streetlight charging pile, and a parking space management method, apparatus, and system thereof. The method comprises: when a reservation request sent by a client is received, whether a vehicle is parked at a current parking space and whether the current parking space is reserved and thus is locked are detected, wherein the reservation request includes reservation information; if no vehicle is parked at the current parking space and the current parking space is not reserved and locked, the current parking space is locked based on the reservation request; and prompting information including the reservation information is outputted, wherein the prompting information is used for prompting the reservation and locking of the current parking space. Therefore, technical problems that the ground is destructed and the construction process is complicated because parking space management of the streetlight charging pile is realized by using an electric parking lock in the prior art can be solved.

The invention provides an FPGA based multi-channel data recording and playback method. With a method for setting a data selector and adding or stripping marks, a function for completing the recording of multi-channel data working synchronously by a one-time recording operation can be achieved; and meanwhile, when a single task formed by one-time recording is in the playback operation, data can be returned through corresponding channels without packet loss. The multi-channel data recording and playback method can be used for recording multi-channel real-time data working synchronously, and the data can be played back at any time when needed to reproduce a test scenario. According to multi-channel data recording and playback method, the data can be effectively managed and used, the function of a data switch is replaced to a certain extent, the system design is simplified, and the system cost is reduced.

The invention discloses a human resource management system based on software as a service (SaaS). The human resource management system based on SaaS is divided into six levels which are an operation interface, an application service layer, an application integration layer, a SaaS service platform, a foundation framework layer and a data service layer in sequence. The human resource management system based on SaaS is divided into six modules which respectively are a human resource planning module, a recruitment and deployment module, a training and development module, a performance management module, a salary and welfare management module and a labor relation management module. The human resource management system based on SaaS is beneficial to achieving aims of effective planning, organizing, controlling and using of the human resource with investment as little as possible on the foundation of the existing information technology (IT) infrastructure.

Performance of a heterogeneous multiprocessor is educed as much as possible within a short time without any awareness of parallelization matched with a configuration of the heterogeneous multiprocessor. In a heterogeneous multiprocessor system, tasks having parallelism are automatically extracted by a compiler, a portion to be efficiently processed by a dedicated processor is extracted from an input program being a processing target, and processing time is estimated. Thus, by arranging the tasks according to PU characteristics, scheduling for efficiently operating a plurality of PU's in parallel is carried out.

The invention discloses a circulating water closed system corrosion inhibitor as well as preparation and application methods thereof. The corrosion inhibitor is composed of the following components inpercentage by mass: 30-50% of a silicate, 10-15% of a natural dispersant, 5-15% of a carboxylate, 1-3% of a copper corrosion inhibitor, and the balance of soft water; and the preparation method of the corrosion inhibitor includes the steps of preparing the copper corrosion inhibitor, pumping a quantitative inorganic silicate or organic silicate into a reaction kettle, performing stirring until all the materials are dissolved, and adding the natural dispersant, the carboxylate and the copper corrosion inhibitor into the reaction kettle, and includes other steps, so that finally the product corrosion inhibitor is obtained. The corrosion inhibitor provided by the invention has stronger chemical adsorption at the metal surfaces, slows anode and cathode reactions, relieves the corrosion of a soft water system material, has strong corrosion inhibition performance and long effective time, and forms a composite membrane protection system to protect a device against corrosion; and the preparation method of the corrosion inhibitor is scientific, and the corrosion inhibitor has significant effects when being used for water treatment in a steel plant.

The invention discloses a foam dewatering agent. The foam dewatering agent is prepared by the following raw materials by weight percentage: 5-10% of triethylene tetramine, 10-20% of diethylenetriamine, 1-30% of oleic acid, 2-10% of glacial acetic acid, 5-15% of maleic anhydride, 5-10% of acrylic acid, 2-7% of citric acid, 5-30% of imidazoline, 5-30% of LAS, 5-10% of HCl aqueous solution with the mass percentage concentration of 20%, 5-10% of NaOH aqueous solution with the mass percentage concentration of 30% and 10-30% of water. The foam dewatering agent integrates foam dewatering, corrosion inhibiting and antiscaling functions, as one potion has the functions such as foam dewatering, corrosion inhibiting and antiscaling and the like at the same time, so that one-time filling-up can replace the traditional three-time respective filling-up, thus reducing the cost, simplifying the process without affecting the functions and prolonging the period of validity. The invention also disclosesa method for preparing the foam dewatering agent.
