Heat-and-cold recovery system based on liquid cooling data center (energy storage power station) includes high-temperature heat pump, pressure-less heat-storage tank, pressurized heat-storage tank, absorption-type water chiller group, compression-type water chiller group, water cold-storage tank, and PCM cold-storage tank. High-temperature heat pump forms circulating heat-exchange loops with CDU and with pressure-less heat-storage tank; hot-water output interface of pressure-less heat-storage tank connects to pressurized heat-storage tank through first circulating pump set and pipeline heater sequentially; pressurized heat-storage tank stores and outputs hot water/steam; pressurized heat-storage tank connects to absorption-type water chiller group through second circulating pump set and forms circulating heat-exchange loop with pressure-less heat-storage tank through absorption-type water chiller group; absorption-type water chiller group forms circulating heat-exchange loop with computer-room air-cooling region; compression-type water chiller group connects to water/PCM cold-storage tank, which stores cooling water of compression-type water chiller group for heat exchange to CDU and/or computer-room air-cooling region.

Disclosed is an operation and maintenance method and system for automatically and uniformly managing nodes of bastion host. No matter distribution of user permission, daily deployment of machine monitoring and network monitoring or batch management of daily operation and maintenance, the operation and maintenance method and system can be abstracted as follows: master control dispatches a Master of a certain area node to issue and execute a certain task, and unified management is naturally achieved; the design concept can be continued subsequently. A Master host in the node serves as a master controller of the node, and related contents including a tool script library, a crontab task and a configuration file are preset in a Redis of the node in advance; when a new machine is accessed to a certain node, the new machine is configured to perform Salt-Master access management of the node where the new machine is located, and the corresponding machine is controlled to complete the corresponding task through a takeover program; therefore, unified and automatic management is realized.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a scan-to-pay method are provided. One of the methods includes: receiving a payment request from an operator of a mobile device; and generating a payment code based on the payment request, wherein the payment code comprises first information and second information, with the first information associated with an payment account, and the second information associated with at least one recent behavioral biometric signature of the operator and at least one historical behavioral biometric signature recorded in the mobile device. This scan-to-pay method provides robust risk control with substantially reduced cost, therefore it provides a more friendly user experience on a scan-to-pay application over its conventional counterparts.
