Description

Technical Field

[0001] The present invention belongs to the technical field of power management, and in particular relates to a power management system based on wireless transmission. Background Art

[0002] Power management based on wireless transmission becomes necessary when operating instruments and equipment in unmanned reconnaissance stations or outposts at the border, unmanned reconnaissance vehicles or work vehicles, in highly dangerous working environments, or in forest fire monitoring and patrols where non-contact, unattended operation of instruments and equipment is required.

[0003] At present, wireless power management still has shortcomings in terms of complete functions, status monitoring, intelligent management, and human-computer interaction, mainly including:

[0004] 1) The management function is single, such as only having a single power-on and power-off wireless control;

[0005] 2) The management method lacks status monitoring and does not have the working status monitoring of each part of the power supply system. The complete working status of the power supply system cannot be known without contact or without personnel approaching;

[0006] 3) The management method lacks intelligent management decision-making functions. In the absence of contact or personnel approaching, it does not have the logical judgment on whether the working status of each part of the power supply system is normal. When an abnormality occurs, it cannot make timely and accurate decisions and handle it, resulting in hidden dangers. The reliability and intelligence levels are low. Summary of the invention

[0007] The purpose of the present invention is to provide a power management system based on wireless transmission, so as to simultaneously control the power-on, power-off, charging, abnormality handling and other actions of the power system, monitor the working status of each part of the power system in real time, make management decisions in time when an abnormality occurs, and avoid damage to load equipment.

[0008] To achieve the above object, the present invention adopts the following technical solution:

[0010] In another example, when the power system is powered on, the power-on instruction of the handheld terminal is operated, and the first wireless transceiver module sends the power-on instruction to the second wireless transceiver module through the wireless communication module. After the second wireless transceiver module receives the power-on instruction, it sends the instruction to the power management module through the wired communication module. The power management module sends a control instruction to the power control module through the wired communication module based on the instruction parsing result. The control instruction received by the power control module controls the power-on operation of the relay module and the power subsystem.

[0011] In another example, the second wireless transceiver module is used to receive control instructions of the handheld terminal and monitoring data and status warning information of the status monitoring module and the power management module, and send the received data and status warning information to the handheld terminal through the wireless communication module.

[0015] In another example, the power management module receives the power system status data sent by the status monitoring module, and generates a power management decision instruction based on the various status data. When the battery pack power is low, a charging start instruction is generated and a low power warning message is sent to the second wireless transceiver module. When the power supply branch current is abnormal, an instruction to shut down the power supply of the power supply branch is generated and a current abnormality warning message is sent to the second wireless transceiver module; when the power supply branch voltage is abnormal, an instruction to shut down the branch power supply is generated and a voltage abnormality warning message is sent to the second wireless transceiver module; when the charging voltage and current are abnormal, a charging stop instruction is generated and a charging function abnormality warning message is sent to the second wireless transceiver module; when the ambient temperature and battery pack temperature are abnormal, a temperature abnormality warning message is sent to the second wireless transceiver module.

[0024] Figure 2 for Figure 1 The schematic diagram of the working process of the power management system is shown in the figure. As shown in the figure, the system includes the following working processes:

[0025] (1) Power on the power system

[0026] After the handheld terminal is working, the power-on instruction of the handheld terminal is operated, and the first wireless transceiver module sends the power-on instruction to the second wireless transceiver module through the wireless communication module. After the second wireless transceiver module receives the power-on instruction, it sends the instruction to the power management module through the wired communication module.

The control instruction received by the power control module controls the power-on work of the relay, the power subsystem, etc., and the above operations realize the power-on of the power system.

[0027] (2) Wireless transmission and reception

[0028] The second wireless transceiver module is used to receive control instructions from the handheld terminal and monitoring data and status warning information from the status monitoring module and the power management module, and send the received data and status warning information to the handheld terminal through the wireless communication module. When the power system is in a non-working state, the second wireless transceiver module is in a silent low-power working mode, waiting for remote transmission instructions from the handheld terminal. The above operations realize the wireless transceiver function of instructions and data.

[0029] (3) Power control

[0030] The power control module is used to receive control instructions from the power management module. After parsing the instructions, the power control module controls the power subsystem and the relay module according to the instruction parsing results to implement power control functions such as powering on or off the power subsystem, starting or shutting down the charging function, and minimum working mode.

[0031] (4) Condition monitoring

[0032] After the power supply system is working, the status monitoring module automatically collects power supply system status data such as voltage, current, battery pack voltage, charging voltage and current of each power supply branch through the digital-to-analog conversion module, collects ambient temperature and battery pack temperature data through the temperature acquisition module, and judges the remaining power of the battery pack according to the battery pack voltage, judges the overcurrent state and whether it is abnormal according to the power supply branch current, judges the output voltage overvoltage or undervoltage state according to the power supply branch voltage, judges the working state of the charging module according to the charging voltage and current data, judges the working environment of the power supply system and the over-temperature state of the battery pack according to the ambient temperature and battery pack temperature, and sends the above collected data and status monitoring judgment result data to the second wireless transceiver module and the power management module. The above operations complete the power supply system status monitoring function.

[0033] (5) Power Management

[0034] The power management module receives the power system status data sent by the status monitoring module, and generates a power management decision instruction according to each status data. When the battery pack power is low, a charging start instruction is generated and a low power warning message is sent to the second wireless transceiver module. When the power supply branch current is abnormal, such as overcurrent or short circuit, an instruction to shut down the power supply of the power supply branch is generated and a current abnormality warning message is sent to the second wireless transceiver module. When the power supply branch voltage is abnormal, such as overvoltage or undervoltage, an instruction to shut down the branch power supply is generated and a voltage abnormality warning message is sent to the second wireless transceiver module. When the charging voltage and current are abnormal, a charging stop instruction is generated and a charging function abnormality warning message is sent to the second wireless transceiver module. When the ambient temperature and the battery pack temperature are abnormal, a temperature abnormality warning message is sent to the second wireless transceiver module. The above decision instructions are all sent to the power control module. The power management function is completed through the above process operation.

[0035] The second wireless transceiver module receives the control command of the handheld terminal and sends the control command to the power management module. After receiving the command, the power management module makes a management decision and sends the decision to the power control module in the form of a control command. The power control module controls the power subsystem and the relay module according to the control command to realize the power on and off of the power subsystem. After the power supply system is powered on, the status monitoring module collects and obtains the voltage and current data of each power subsystem, the voltage and power data of the battery pack, the charging supply voltage and current, and the environment and battery pack temperature data, calculates and judges the corresponding working state according to the collected data, and sends these data and the monitoring state to the power management module and the second wireless transceiver module. After receiving the monitoring state, the power management module makes a management decision and sends the decision to the power control module in the form of a control command. The power control module performs the corresponding control action according to the command state. After receiving the data and the monitoring state, the second wireless transceiver module sends these data and the state to the wireless transceiver handheld terminal through the wireless communication module. The operator automatically learns the overall working state of the power system through the wireless transceiver handheld terminal and can complete various functions of power management by operating the wireless transceiver handheld terminal.

[0036] Among them, the power management module is the core module, which interacts with the second wireless transceiver module, the power control module, and the status monitoring module respectively to establish constraints and make management decisions and dispatch control instructions based on the control instructions sent by the second wireless transceiver module and the power subsystem working status information sent by the status monitoring module.

[0037] The second wireless transceiver module is connected to the wireless transceiver handheld terminal through wireless communication, and is used to receive the control instructions sent by the wireless transceiver handheld terminal. At the same time, it is connected to the status monitoring module and the power management module through wired communication, and is used to receive the collected data and status information sent by the status monitoring module, forward the control instructions to the power management module, and send the collected data and status monitoring information to the host computer. When the power system is in a non-working state, the second wireless transceiver module is in a silent low-power working mode, waiting for the remote transmission instructions from the wireless transceiver handheld terminal.

[0038] The wireless transceiver handheld terminal is used to receive the operator's control instructions. At the same time, it provides human-computer interaction to the operator and displays the data and working status of each part of the power system.

[0039] The power control module is connected to the power management module via a wire, and is used to receive the management decision control instructions of the power management module. At the same time, according to the received control instructions, the power subsystem and the relay module are controlled to complete the power management functions such as powering on and off each power subsystem;

[0040] The power subsystem and relay module shown are used to receive control instructions from the power control module and switch the power subsystem and relay on or off according to the control instruction status.

[0041] Among them, the status monitoring module is connected to each power supply part of the power system through wires, and is used to collect power system status data such as voltage, current, battery pack voltage, charging voltage and current of each power supply branch through the digital-to-analog conversion module after each power supply branch of the power system is working, and collect ambient temperature and battery pack temperature data through the temperature acquisition module, and judge the remaining power of the battery pack according to the battery pack voltage, judge the overcurrent state and normal working state according to the power supply branch current, judge the output voltage overvoltage or undervoltage state according to the power supply branch voltage, judge the working state of the charging module according to the charging voltage and current data, judge the working environment of the power system and the over-temperature state of the battery pack according to the ambient temperature and battery pack temperature, and send the above collected data and status monitoring judgment result data to the second wireless transceiver module and the power management module.

[0042] In another embodiment, replacing the wireless transceiver handheld terminal and the second wireless transceiver module with a digital radio or a high-power wireless transmission system can greatly enhance the wireless transmission distance, improve the remote control capability, and realize long-distance wireless control capability.

[0043] In another embodiment, the first wireless transceiver module and the second wireless transceiver module have a wireless networking function, so that multiple wireless power management systems are constructed into a wireless networking link, forming a network management mode, and realizing information sharing and master-slave hierarchical management, thereby improving management efficiency and wireless management scale.
