The invention discloses a low-power-consumption whole vehicle controller integrated with a gateway function. The low-power-consumption whole vehicle controller comprises a main control unit, a gatewaycommunication processing unit, an advanced power management unit, an input signal processing unit, an output processing unit, a system storage unit and a breakdown processing unit. A power supply unit supplies electricity to a storage battery, electricity is supplied to a system and a circuit on the periphery of the system by outputting stable voltage through the power supply unit, and normal working of the system is ensured. The main control unit is in data connection with the input signal processing unit, the output processing unit, the storage unit, a breakdown diagnosis unit and the gateway communication unit through a high-speed SPI communication interface, an AD port and a CAN interface, and network information interconnection of a whole vehicle CAN bus is achieved. The low-power-consumption whole vehicle controller can be applied to the situation that a main control unit with pure electric and hybrid vehicle models serving as wholes vehicles coordinates all sub-controllers to work, the new energy whole vehicle controller function is achieved functionally, the gateway function is also achieved, the number of vehicle body electronic controllers is reduced, and the vehicle body space is effectively utilized.

The invention relates to an electric vehicle controller sleep wake-up system and a control method thereof. The system comprises a CAN chip with a wake-up function, a logic gate circuit, a PWR Module,an MCU and switch module. The switch module is additionally arranged before the PWR circuit module, and on/off of the switch module is controlled through the logic gate circuit so as to control the working power supply of the CAN chip and the MCU to be disconnected when the controller is static and minimize the static power consumption of the controller. Then the characteristic that the CAN chip with the wake-up function can monitor the CAN message of the CAN bus and send out a wake-up signal under the condition that the working power supply is disconnected is utilized, the switch module is controlled to be closed by using the signal to trigger the logic gate circuit and the MCU and the CAN chip are powered on again so as to support the controller to resume the working mode again. The system has low static power consumption and has simple circuit structure and high success rate of CAN sleep wake-up.

The embodiment of the invention discloses a remote wake set top box method, a set top box and a system; the method comprises the following steps: a tuning unit demodulates a received network signal to obtain a TS current signal and transmits the TS current signal to a singlechip; whether the set top box is needed to be waked is determined according to the TS current signal by the singlechip; in the embodiment of the invention, the power supplying to the tuning unit is carried out under a real standby state of the set top box, the set top box is determined to be waked by the TS current signal obtained by the tuning unit, so as to wake the set top box at any time by an operator under the real standby state of the set top box.

The invention provides a chip awakening method and system, electronic equipment and a readable storage medium. The chip awakening method is applied to the chip awakening system, and comprises the following steps: acquiring a working state of a chip, receiving an awakening trigger instruction and generating an awakening instruction when the chip is in a to-be-awakened state, and outputting the awakening instruction through a power supply of the chip through an awakening control module. And when it is confirmed that the wake-up instruction is the abrupt change continuous signal meeting the preset wake-up condition, the chip is awakened to enter the normal working state, effective resources of the chip can be fully utilized, dependence on idle I/O of the chip is not needed, and wake-up of the chip can be achieved in a lower power consumption mode.

The method is suitable for the technical field of battery pack management, and provides a battery pack awakening method and device, electric equipment and garden equipment; the battery pack awakeningmethod comprises the steps that after a high-level signal sent by a second BMS is received, a first BMS is converted into a working state from a dormant state; the high-level signal is converted intoan output level signal; and the output level signal is sent to the second BMS, so that the second BMS is converted into the working state from the dormant state. According to the embodiments of the invention, the battery pack can be charged by a battery pack without needing a pressing key or an external activation operation, so that the operation is simple and convenient.

The invention provides a communication control method of a mobile terminal, a communication control device of the mobile terminal, a communication control device and a computer readable storage medium, and relates to the technical field of communication. The communication control method of the mobile terminal comprises the following steps: monitoring a Bluetooth signal through a Bluetooth unit in a shutdown state of the mobile terminal; when the Bluetooth signal sent by the target object is monitored, waking up an ultra wide band (UWB) unit; and performing ultra wide band communication with the target object through the UWB unit. According to the method and the device, the mobile terminal can perform ultra-wideband communication with the target object in the shutdown state.

The embodiment of the invention provides a cross-network awakening method and related equipment, and the method comprises the steps: transmitting an awakening instruction to proxy equipment maintaining heartbeat connection through an Internet of Things platform, and then transmitting an awakening message to to-be-awakened Internet of Things equipment deployed in the same private network with the proxy equipment through the proxy equipment, the to-be-awakened Internet of Things equipment is awakened and connected with the Internet of Things platform so that cross-network awakening of the to-be-awakened Internet of Things equipment deployed in the private network by the Internet of Things platform deployed in the public network is realized, and the problem that after public and private network address mapping fails, messages of the Internet of Things platform cannot reach the Internet of Things equipment through the NAT equipment, and the Internet of Things equipment cannot receive the message can be solved.

The invention relates to a wireless positioning device and method capable of being awakened in real time. The wireless positioning device comprises a single-chip microcomputer, a wireless communication module, a positioning module and a WIFI module, wherein the wireless communication module, the positioning module and the WIFI module are connected with the single-chip microcomputer. The single-chip microcomputer awakens and activates the wireless communication module to establish connection with a server at a preset time interval. When the wireless positioning device receives a positioning mode switching instruction of the server, the wireless positioning device activates the WIFI module or the positioning module to perform positioning, and reports the positioning position information to the server. According to the invention, the wireless positioning device can be awakened at the preset time interval, the power consumption is low, and the balance between timeliness and power saving isachieved.
