Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of an apparatus data uploading method provided in an embodiment of the present application, and the specific steps of the embodiment may include:
s101: receiving device data transmitted by the host device;
the execution main body of the embodiment can be an internet of things module, and the internet of things module is a key link for linking the internet of things sensing layer and the network layer. Data generated by all the terminals of the Internet of things can be uploaded to a remote server through the Internet of things module, so that the server can conduct remote control. The internet of things module in this embodiment is connected with the host device through a USB Bus (Universal Serial Bus), and the host device can transmit device data to the internet of things module through the USB Bus and can also provide electric energy for the internet of things module by using a VBUS (Bus voltage) signal in the USB Bus.
Specifically, the present embodiment does not limit the type of the host device, and the host device may be an ultrasonic diagnostic apparatus or an endoscope, for example. The internet of things module can receive the device data transmitted by the host device through the USB bus. The host device may transmit the device data to the internet of things module when a specific condition is triggered, or may transmit the device data to the internet of things module according to a preset period, and the content and the category of the device data are not limited in this embodiment. For example, when the host device has a device fault, the host device may transmit a fault code corresponding to the device fault, that is, device fault information, to the internet of things module according to the 32-bit fault code definition packet, where the fault code is equivalent to the device data mentioned above. For example, the host device may transmit longitude and latitude coordinates of a current location of the host device, that is, device location information, to the internet of things module according to a preset period. When the internet of things module uploads the fault code to the server, the server can perform remote fault analysis and fault diagnosis operation according to the fault code. When the internet of things module uploads the longitude and latitude coordinates to the server, the server can judge whether the host equipment is moved or not by combining the historical longitude and latitude coordinates, and then judge whether the host equipment is stolen or not.
S102: acquiring the bus voltage of the USB bus, and determining the working state of the host equipment according to the bus voltage;
the purpose of this step is to determine whether the host device is in a powered-down state. When the host equipment is in a power-off state, the bus voltage of the USB bus between the host equipment and the Internet of things module is reduced to 0V, so that the working state of the host equipment can be determined by acquiring the bus voltage of the USB bus, and whether the host equipment is in the power-off state or not is further judged. Specifically, the internet of things module may determine whether the host device is in a power-off state through a VBUS signal and a communication protocol on the USB bus.
S103: when the host equipment is in a power-off state, the battery module of the Internet of things module is set as a current power supply so as to upload the equipment data by using the electric energy of the battery module.
The method comprises the following steps that the step is established on the basis that the host equipment is in a power-off state, and at the moment, the Internet of things module cannot upload equipment data by using electric energy provided by a VBUS signal of the USB bus. Because the data transmission rate of the internet of things module is limited, after the host device transmits the device data to the internet of things module, the internet of things module may not upload all the device data in real time, and therefore the internet of things module can store the received device data to the local database and continuously upload the device data to be transmitted in the local database. Specifically, the local database mentioned in this embodiment may be a database of the module of the internet of things, for example, the local database may be a flash memory of the module of the internet of things. In the conventional technology, when the internet of things module and the host device are powered off synchronously, if the data storage space has the device data which is not uploaded yet, the internet of things module cannot continuously upload the device data, so that the data transmission efficiency is low. When detecting that host equipment is in the power-off state in this application, will the battery module of thing networking module sets up to current power, provides the electric energy of uploading equipment data through battery module. Even if the host device is powered off in the above embodiment, the internet of things module can still use the electric energy in the battery module to continuously upload the device data to the cloud server, so that the cloud server executes corresponding processing operation according to the device data, and the situation of data upload interruption caused by the power-off of the host can be avoided.
When the host equipment is in a power-on state, the Internet of things module takes the host equipment as a current power supply and uploads equipment data to the cloud server; when the host equipment is in a power-off state, the battery module is used as a current power supply by the Internet of things module, and the equipment data are uploaded to the cloud server. That is to say, this embodiment carries out the switching of current power when detecting that the host computer equipment is down to power, utilizes the electric energy that battery module provided to continue to upload equipment data, has avoided the host computer to be down to the influence of uploading equipment data.
In this embodiment, the internet of things module determines the working state of the host device according to the bus voltage of the USB bus connected to the host device, and when the host device is in the power-on state, the host device can transmit device data on the bus through the USB and provide electric energy required by working for the internet of things module. When the host equipment is in a power-off state, the Internet of things module sets the battery module of the Internet of things module as a current power supply, and the battery module is used for providing electric energy required by uploading equipment data. The embodiment can reduce the dependence of the data transmission of the Internet of things module on the working state of the host, and improve the data transmission efficiency.
As a possible implementation manner, the operation of S102 determining the operating state of the host device according to the bus voltage in the embodiment corresponding to fig. 1 may include the following steps:
step 1: judging whether the bus voltage is 0 or not; if yes, entering step 2; if not, entering step 3;
step 2: and judging that the working state of the host equipment is a power-off state.
And step 3: and judging that the working state of the host equipment is a power-on state.
As a possible implementation manner, after receiving the device data transmitted by the host device, the embodiment corresponding to fig. 1 further includes the following steps:
step 1: storing the device data in a local database;
step 2: and when the equipment data is uploaded, deleting the equipment data stored in the local database.
The rate of uploading the device data by the internet of things module is greatly influenced by network environment fluctuation, so that after the device data transmitted by the host device is received, the internet of things module possibly cannot upload all the device data in real time, and therefore the internet of things module can store the received device data to a local database of the internet of things module and continuously upload the device data to be transmitted in the local database. When the device data is uploaded, the device data saved in the local database may be deleted, so as to release the available storage space of the local database.
As a possible implementation manner, in the embodiment corresponding to fig. 1, when the host device is in a power-off state, the operating state of the internet of things module may be set to a sleep state, so that a power consumption current of the internet of things module in the sleep state is smaller than a target current; the target current is the power consumption current of the internet of things module in a normal working state.
When detecting that the host equipment is in the power-off state, the above embodiment switches the working state of the internet of things module from the normal working state to the dormant state, so as to reduce the power consumption of the internet of things module in the power-off process of the host equipment. As a feasible implementation scheme, when the working state of the internet of things module is set to the dormant state, the data transmission function of the internet of things module can be only started, so that the overall power of the internet of things module is reduced, and the remaining operable time of the internet of things module is conveniently prolonged.
Further, when the need _ clk signal of the USB bus is detected, it indicates that the host device is in a power-on state, the current power supply may be switched to the host device, and the operating state of the internet of things module is set to the normal operating state. The new _ clk signal is a clock signal generated during the mounting process of the USB device. After the working state of the IOT module is set to the normal working state, all functions of the IOT module can be recovered. As a possible solution, after the current power supply is switched to the host device, a charging operation may also be performed on the battery module using the USB bus.
The flow described in the above embodiment is explained below by an embodiment in practical use. Referring to fig. 2, fig. 2 is a hardware schematic diagram of a host device and an internet of things module according to an embodiment of the present disclosure.
When the host equipment works normally, the internet of things module is communicated with the host equipment through the bus and uploads the received equipment data to the cloud server. The internet of things module can monitor the bus voltage of the USB bus according to a preset period so as to acquire the working state of the host device. Specifically, the internet of things module can judge whether the PC is in a power-off state through the VBUS signal and the communication protocol on the USB bus. When the VBUS voltage is reduced to 0V, the Internet of things module can start a sleep program to enter a sleep state, and the power consumption current of the Internet of things is reduced to be below 10 Ua. The internet of things module in the dormant state can continuously upload equipment data based on the power supply of the battery module. The internet of things module can upload equipment data in a narrow-band communication mode. When the host equipment is powered on, the VBUS voltage is rapidly increased to 5V, the USB bus is activated, the Internet of things module wakes up the Internet of things module through a need _ clk signal on the bus to re-enter a normal working mode, the power consumption is about 40mA at the moment, and the battery module of the Internet of things module is charged through the USB bus.
The internet of things module flexibly determines whether to sleep or not by monitoring the VBUS signal, power consumption of the internet of things module can be greatly saved when the host equipment is shut down, and then the internet of things module is awakened in time by using the need _ clk signal of the USB, so that the internet of things module can process messages in time when the PC works normally.

When the host equipment is in a power-off state, the Internet of things module sets the battery module of the Internet of things module as a current power supply, and the battery module is used for providing electric energy required by uploading equipment data.
