Description

System program upgrading method, system and storage medium for electric bed with communication unit

Technical Field

The application relates to a method and a system for updating programs of an electric bed system, in particular to a method and a system for remotely updating firmware programs of the electric bed system.

Background

An electric bed generally includes a main controller, sensors provided at certain structural positions of the electric bed and communicating with the main controller to transmit information of the electric bed, such as posture information, to the main controller, and a motor assembly communicating with the main controller to adjust the posture of the electric bed. The electric bed may further include a communication unit communicatively connected to the main controller to receive instructions and data from an external device, such as a smart terminal, a remote controller, and the like. The communication unit may be a wireless communication unit, which may be, for example, an infrared unit, a unit based on the bluetooth protocol, a unit based on the WIFI protocol, or a unit based on the 3g,4g,5g wireless communication protocol. Can establish wireless communication through wireless communication unit and intelligent control equipment, for example cell-phone, panel computer, indoor intelligent control terminal, smart television, even other intelligent equipment etc. and connect to realize the control to the beddo.

However, the control program of the main controller of the electric bed and the embedded control programs (also called firmware) of the sensor unit, the communication unit and other units are all cured in advance when the electric bed leaves the factory, and if the product needs to be upgraded because of the functions, a company needs to send a professional worker, use a professional tool, or even disassemble the device to upgrade the firmware, so that after-sale maintenance is very troublesome, and the cost is very high.

A common upgrading method in the prior art is shown in fig. 1, and includes using an intelligent terminal, typically a PC, for example, a notebook computer, to connect a main controller and/or a sensor of an electric bed through a flat cable by using a professional upgrading device, so as to upgrade firmware of components such as a control program and/or the sensor in the main controller. In the upgrading step, shells of a main control box or a sensor and the like are generally required to be opened, a flat cable is used for connecting an interface of an object to be upgraded with a professional upgrading tool, the professional upgrading tool is connected with a PC through a USB, and professional upgrading software of the PC is opened to upgrade the product.

However, this upgrading method is very inconvenient, and besides the non-professional personnel being unable to operate, even professional personnel need to visit the site in person to upgrade the electric bed, which causes huge workload for later maintenance of the electric bed and causes huge cost.

With the development of electric beds, electric beds having a bluetooth communication unit have appeared, which can communicate with any smart device having a bluetooth function, and receive a control instruction transmitted through a control program installed on the smart device. By replacing the traditional infrared-based remote controller with the Bluetooth communication unit, the control distance of the electric bed is prolonged. However, in this mode, the problem of upgrading the electric bed is still not solved, and the user of the electric bed is still unable to upgrade the control program of the electric bed and the firmware of each unit of each electric bed at will.

Wherein the main control box 1 is composed of a Bluetooth communication unit 120, a main controller 120 connected with the Bluetooth communication unit through a communication line 150, and a bus interface unit 140 communicatively connected with the main controller 120 through a communication line 151. The main control box is communicatively connected to the

expansion units

31, 32 via a bus 141 and a splitter 142. The bluetooth communication unit 110 may be connected to the main controller 120 through a duplex serial communication line, the bus interface unit 140 is connected to the bus 141, and the bus 141 finally connects all the

extension units

31, 32, etc. to the main control box 10 through the splitter 142. The main controller may here be a processor based on any architecture, for example a processor based on the ARM architecture, the bluetooth communication unit may be a bluetooth 2.0, 3.0, 4.0, 5.0 compatible communication unit, and the

extension units

31, 32 may be one or more of a sleep sensor unit, a light strip controller unit, a voice controller unit, an aromatherapy controller unit, a heat blanket controller unit.

Fig. 3 shows a schematic diagram of the physical architecture of an electric bed system software automatic upgrade system according to another embodiment of the present application. According to fig. 3, the bluetooth communication unit 110 is communicatively connected to a control program P201 for the electric bed running on the smart device 200 running a control program, which may be software, an applet, or an Application (APP), via a bluetooth communication protocol, and the control program P301 is configured to be communicatively connected to a remotely deployed server 300, for example, via internet communication, based on one of a plurality of network protocols such as WIFI, TCP/IP, 3G,4G,5 communication protocols, etc. In this embodiment, the main control box 10 of the electric bed further includes a lifting motor control unit 121 for controlling the lifting motor 21, and a massager control unit 122 for controlling the massager 22, wherein the massager control unit 122 for controlling the massager 22 is directly connected to the main controller 120. A memory 130 may also be included, communicatively coupled to the master controller 120 via a communication line. The memory provides additional storage space for the master controller 120, such as storage space for upgrade files for the master controller 120.

The control program P201 of the electric bed is configured to establish a communication connection with the server 300 upon start-up of the control program, step S21, and send a request to the control program P301 of the server 300 for obtaining a latest software version information set of the current electric bed, the information set including a version number of the latest software and hardware version information compatible with the version number of each latest software, step S22. The reason why it is necessary to provide the hardware version information compatible with each latest software version number is that the smart device can control a plurality of electric beds, and the hardware version of each electric bed may be different.

Thereafter or simultaneously, an inquiry command for starting the bluetooth control unit to collect its own version information, collecting the version information directly to other hardware units, for example, collecting the version information to the main controller 120, and optionally collecting the version information of each

extension unit

31, 32, 33, 34 by the main controller 120 to obtain the version information of all hardware units is sent to the bluetooth control unit 110, step S23. Similarly, the version information includes current software version information as well as hardware version information. The version information of each hardware unit may include identification information of the hardware unit, for example, information identifying that the hardware unit is a master controller, a bluetooth communication unit, and any one of the extension units, so that the smart device control software P201 performs comparison according to the identification information.

The smart device control software P201 is configured to wait and receive the latest software version information set from the server and the version information from the bluetooth communication unit 110, step S24; after receiving the information set and the version information, comparing the information set and the version information for each hardware unit, wherein whether the current software version information is equal to the version information in the latest software version information set is judged, and step S251; if the same, no available upgrade is prompted, if different, the hardware information part is compared to determine whether the hardware version information is included in the hardware compatible information in the latest software version information set, if yes, the hardware unit is prompted to have an upgradable upgrade file, if no, no available upgrade is prompted, and step S2521. For example, the latest version of software provided by the server of the light strip controller unit is VF3.5, which supports hardware version VH2.0 or more, but the current software version VF2.3 of the light strip controller is hardware version VH1.5, so that the software is judged as unable to be upgraded or not to be upgraded because the hardware version is too low. It should be understood that in the comparison, the hardware version information may be compared first, then the software version information may be compared, and then a prompt indicating that an upgrade is available may or may not be generated according to similar logic based on the comparison result.

The prompt of the available upgrade may be displayed on the display screen of the smart device by the smart device control software P201 and set an operable object for the smart device to receive an operation of the user on whether to download the available upgrade, for example, a selection button may be provided, when the user selects to download the available upgrade through the input unit of the smart device, step S2522, the control software P201 sends a request for downloading an upgrade file corresponding to the available upgrade to the control software P301 of the server, step S2523, if there are multiple available upgrades, the multiple available upgrades may be simultaneously prompted, an operable object for the multiple available upgrades is set, an operation of the user on whether to download the multiple available upgrades is received, and a request for downloading the upgrade file is sent to the server correspondingly.

Optionally, after determining that a certain hardware unit has an available upgrade, the control software P201 does not prompt that an available upgrade exists, but directly requests the server control software P301 to download an upgrade file corresponding to the available upgrade, or does not prompt that an available upgrade exists through the control software P201, but directly requests the server control software P301 to download an upgrade file corresponding to all available upgrades after the judgment on whether all the hardware units have available upgrades is completed, step S253.

Thereafter, the smart device control software P201 waits for the start of the download process and receives the upgrade file of the available upgrade, for example, after the start of the download process, step S26. When it is determined that all upgrade files, for example, all upgrade files available or selected upgrade files available, are downloaded, step S27, transmission to the bluetooth communication unit is started, step S28.

The upgrade program P101 operated by the bluetooth communication unit 110 as described above collects the current version information of each hardware unit upon receiving the inquiry command, step S11, and provides it to the smart device control program P201 after the collection is completed, step S12. The collection according to the inquiry command may be performed only for the bluetooth communication unit, or only for the bluetooth communication unit 110 and the main controller 120, optionally may be performed for each extension unit by the main controller. For example, the collection of the version information of the bluetooth communication unit comprises collecting the current firmware version information and collecting the hardware version information; the collection of the master controller 120 includes collecting firmware version information thereof and collecting hardware version information thereof. Optionally, the information acquisition of the drive unit controlled by the master controller may be realized by the master controller. For example: the main controller is used for collecting version information of the control unit 121 of the lifting motor 21 of the electric bed and collecting version information of the control unit 122 of the massage unit 22 of the electric bed.

In some embodiments, in response to the inquiry command, the version information of the bluetooth communication unit 110, the main controller 120, and the

extension units

31, 32, 33, 34 may be inquired at the same process.

The bluetooth communication unit 110 then waits for the upgrade file of the available upgrade to occur for the smart device, and may end the process if the upgrade file of the available upgrade is not received for a period of time.

The upgrade file available for upgrade is sent from the smart device 120 to the bluetooth communication unit 110 in the form of a data packet, where the start data packet may include a transmission start flag, and the end data packet includes a transmission end flag, step 13, where the bluetooth communication unit 110 verifies each received data packet, and optionally verifies the upgrade file as a whole again after receiving the end data packet, step S131.

After receiving an upgrade file, the deployment logic of the upgrade file is as follows:

the bluetooth communication unit 110 determines whether the received upgrade file is an upgrade file for the own bluetooth firmware, step S14;

if yes, after receiving the upgrade file, the bluetooth communication unit 110 automatically completes the firmware upgrade of itself S141;

the bluetooth communication unit 110 determines that the received upgrade file is not the bluetooth firmware upgrade of the bluetooth communication unit, and then the bluetooth communication unit transmits the upgrade file to the main controller unit S142 through the duplex serial communication line, and the main controller unit deploys the upgrade file.

After receiving an upgrade file, the main controller unit judges whether the upgrade file is the upgrade file of the main controller unit or the extension unit according to the flag information of the upgrade file, step S151, if the upgrade file is the upgrade file of the main controller unit, automatically completing the program upgrade of the main controller unit, and step S152; if the upgrade file is the upgrade file of the extension unit, the firmware is sent to the corresponding extension unit through the bus, and the corresponding extension unit automatically completes the program upgrade of the extension unit, step S153.

The deployment may be performed after each upgrade file is received or after all upgrade files have been transmitted.

The upgrading file of the main controller and the upgrading file storage area of the Bluetooth communication unit are respectively positioned in the designated area of the memory in communication connection with the main controller, and the main controller gives a signal allowing storage.

After all the upgrade files are received, the corresponding upgrade files are sent to the devices needing to be upgraded one by one. Or after receiving each upgrade file, the corresponding upgrade file is sent to the device needing to be upgraded.

In some embodiments, after receiving all the upgrade files, the main controller sends the corresponding upgrade files to the devices to be upgraded one by one. In some embodiments, after receiving each upgrade file, the main controller sends the corresponding upgrade file to the extension unit that needs to be upgraded.

In some embodiments, if the upgrade file corresponds to the bluetooth communication unit, storing the upgrade file in an application storage area of the bluetooth communication unit; if the upgrade file corresponds to the main controller, storing the upgrade file in an application storage area of a memory which is in communication connection with the main controller; and if the upgrading file corresponds to the extension unit, storing the upgrading file into an application storage area of the extension unit.

The application storage area is separated from the storage area of the initial firmware program of each hardware unit. This arrangement allows the hardware unit to be restored to the original firmware program if required. So as to avoid the unavailability of hardware units caused by problems in the upgrading process.

The application storage area may be located in the memory 130 communicatively connected to the main controller for the main controller and, for example, the bluetooth communication unit, and different storage areas may be allocated to the hardware units in the memory 130.

In the embodiment of the application, after each hardware unit receives the upgrade file of the device sent by the main control box through the bus, the upgrade file is stored in the upgrade application area of the program, after the storage is finished and the verification is correct, the program jumps to the upgrade application area, and the upgraded program is run.

Each hardware unit of the electric bed described in the present application may have a firmware version solidified when leaving a factory, and after installing a firmware program for upgrading, a user may restore the device to the solidified version when leaving the factory through the APP of the intelligent device 200; if the user wants to restore the factory application version, a command for restoring the factory program of a certain hardware unit can be sent through the mobile phone APP, and after the corresponding hardware unit receives the command, the application program can modify the application starting address into a factory firmware address, so that the effect of skipping from the upgrading application area to the factory application area is achieved, and the factory program is operated.

The server side control software P301 is configured to: the request of the smart device is received after establishing a communication connection with the smart device, step S311, and the latest software version information set is provided to the smart device, step S312. The latest software version information set comprises the version number of the latest software and hardware version information corresponding to the version number of each latest software. Thereafter, the server waits and provides the upgrade file corresponding to the software version number included in the download request to the intelligent device based on the download request of the intelligent device, step S32; wherein the download request is generated for the smart device based on the version information obtained from the communication unit and the determination of the set of latest software version information.

In an embodiment of the present application, each of the upgrade files may include a firmware program for upgrade and a boot program for upgrade, where the boot program for upgrade and the firmware program for upgrade are stored separately, and the boot program for upgrade is stored in a read area of an initial boot area of each of the hardware units so that the hardware units enter the boot program for upgrade after initial boot to call the firmware program for upgrade. Preferably, the firmware program for upgrade and the boot program for upgrade are stored in separate storage spaces. In other embodiments, such as those in which an existing firmware program of a hardware unit is replaced with a firmware program for upgrade, the upgrade files each include only the firmware program for upgrade.

In the above embodiment, the bluetooth communication unit communicates based on a bluetooth communication protocol, and may also replace the bluetooth communication unit with another communication unit, for example, a communication unit based on an NFC near field communication protocol, a bluetooth communication protocol including bluetooth 2.0, 3.0, 4.0, 5.0, a Zigbee protocol, and a local area network communication protocol including WIFI is adopted; the server 300 is remotely deployed with the intelligent device 200, and communication is realized through one or more combinations of various mobile network communication protocols based on 3G/4G/5G, TCP/IP protocol and Internet protocol.

In the embodiment described above, the latest software version information set is pushed by the server 300 after establishing a communication connection with the server 300; the latest set of software version information may also be requested from the server 300 after establishing a communication connection with the smart device 200.

In some embodiments, the upgrade file is transmitted in the form of a data packet, and the data packet includes information on whether the data packet is the last data packet. The server may comprise a file server.

In some embodiments, verifying each received upgrade file includes verifying each received data packet, storing it in a temporary storage area after judging correct transmission, and providing a response to the intelligent device to request sending of a next data packet, and requesting resending if the received data packet is incorrect; when the received data packet is judged to be the last data packet, the data packet is verified, the data packet is stored without errors, then the whole upgrade file is verified, the data packet is stored in the temporary storage area without errors, then a response request is sent to the intelligent device control program P201 to send the next upgrade file, and the verified upgrade file is stored in the corresponding storage area after the upgrade file is verified.

In some embodiments, the latest set of software version information from the server is received after establishing a communication connection with the server. Wherein the server may be configured to push the latest set of software version information after establishing a communication connection with the server; or configured to request the set of updated software version information from the server upon establishing a communication connection with the smart device.

In the above embodiment, the firmware upgrade control program P101 of the electric bed end may be deployed in the bluetooth communication unit, the firmware upgrade control program P201 of the smart device end may be deployed in the smart device end, and the firmware upgrade control program P301 of the server may be deployed in the server, which may interact with each other to implement various functions of the method and system described in this application. The three may also be stored in corresponding memory areas in the form of computer program code, which is executed when necessary to implement the various functions of the method and system described herein. The firmware upgrade control program P101, the firmware upgrade control program P201 of the smart device side, and the firmware upgrade control program P301 of the server may also be regarded as components of an overall firmware upgrade control program, and jointly constitute the firmware upgrade control program.

If the smart device actively discovers or is notified to a server, for example, a collected control software such as APP, that a beddo company has a new firmware update of a beddo product deployed on the cloud server, the smart device prompts a client whether to upgrade firmware according to software and hardware version information of each hardware unit of the beddo obtained from the beddo, where the hardware unit of the firmware may be bluetooth communication unit firmware, main controller unit firmware, or other extension unit firmware. After the user clicks to confirm the upgrade, the APP on the mobile phone downloads the firmware from the server to the mobile phone.

It should be understood by those skilled in the art that the above-mentioned function options and their corresponding firmware update applications of the electric bed are only examples for the purpose of explaining the present application, and should not be construed as any limitation to the present application, and other existing or future function options and their corresponding live broadcast applications, as applicable to the present application, should be included in the scope of patent protection of the present application.
