Description

Low-power-consumption wireless transmission control module and control method Technical Field The invention relates to the technical fields of internet of things (IoT) and wireless communication, in particular to a wireless intelligent control module with low power consumption and a control method thereof, which are particularly suitable for scenes requiring long battery life and high-efficiency data transmission, such as intelligent home, industrial internet of things and intelligent wearable equipment. Background With the rapid development of the internet of things technology, intelligent control modules are widely applied in a plurality of fields. However, conventional intelligent control modules typically employ a single wireless communication module that needs to be responsible for both waking up and data transmission, resulting in the wireless communication module being in an operational state at all times, and because of the need for data transmission, resulting in the wireless communication module being in a high power consumption state at all times. Summarizing, the prior art has the following major problems: the high power consumption operation is that the data transmission channel (such as 4G/5G) of the traditional wireless communication module needs to keep an activated state even when no data is transmitted, consumes a large amount of electric energy and has higher power consumption. The wake-up mechanism has low efficiency, and the traditional 4G/5G wake-up module adopts a bidirectional communication mode, so that confirmation is needed, and the power consumption and complexity of the wake-up process are increased. And the lack of a cooperative work mechanism, namely the lack of an efficient cooperative strategy between wakeup and data transmission, causes frequent switching of a data channel and causes energy waste. The cost and performance balance is difficult to realize significant power consumption reduction and cost control while ensuring communication efficiency. Disclosure of Invention The invention aims to provide a low-power-consumption wireless transmission control module which can reduce the overall average power consumption. To achieve the purpose, the invention adopts the following technical scheme: The low-power consumption wireless transmission control module comprises a first path of wireless communication unit, a second path of wireless communication unit, a controller and a battery, wherein the first path of wireless communication unit and the second path of wireless communication unit are connected with the controller, and the battery provides electric energy for the first path of wireless communication unit, the second path of wireless communication unit and the controller; the first path of wireless communication unit is a wake-up channel and is used for receiving wake-up signals and triggering a controller; the second path of wireless communication unit is a data transmission channel, and is configured to be started after the first path of wireless communication unit receives a wake-up signal, the second path of wireless communication unit is controlled by the controller, and the second path of wireless communication unit adopts a two-way communication mode and is automatically closed after the data transmission to be transmitted is completed. The beneficial effects are as follows: And the ultra-low power consumption is that the wake-up channel and the data transmission channel are separated, so that the data transmission channel with high power consumption is in a closed state most of the time in normal times, only the wake-up channel runs at the ultra-low power consumption all the time, and the data transmission channel with high power consumption only runs when being wake-up, so that the overall power consumption of the device is greatly reduced (which can be as low as one tenth of that of the traditional module). The high-efficiency communication comprises the steps of waking up a channel, wherein the data volume of a waking up signal is very small, so that quick and low-power consumption waking up can be ensured, and the data transmission channel can provide high-speed and reliable data transmission capability, so that different application requirements can be met. The service life of the battery is prolonged, namely, when the battery is used for power supply, the extremely low standby power consumption can obviously prolong the service life (up to several years) of the battery power supply equipment, and the maintenance cost is reduced. The hardware cost has the advantages that the hardware of the communication unit is more flexible in selection, the wake-up channel can be a BLE chip or 433MHz chip or LoRa chip or FM signal chip with low cost, and the data transmission channel can use a 4G/5G module, so that the cost is higher, but the ultra-low power consumption and the service life extension brought by the dual-channel design are cost-effective in the life cycle o
