Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an operating voltage adjusting method according to an embodiment of the present invention, where the present embodiment is applicable to a situation where a current operating voltage of a machine is not adapted to a rated voltage of a battery of the machine, and the method may be executed by a controller according to an embodiment of the present invention, as shown in fig. 1, the method may specifically include:
s101, responding to a working voltage control instruction of a user, and determining the grade of the target voltage to be switched.
The target voltage level is a voltage level which a user wants to adjust according to actual requirements.
In particular, at least two voltage levels of the device are predetermined. The user operates the voltage operation control or the voltage operation key on the machine according to the actually required working voltage value, for example, the user selects a certain voltage grade as a target voltage grade by operating the voltage operation control, and then generates a working voltage control instruction according to the voltage grade selected by the user. Alternatively, the user may replace the battery of the device as needed, and generate the operating voltage control command of the user based on the replaced battery, for example, by setting the voltage class to which the replaced battery voltage belongs as the target voltage class.
And S102, generating a voltage grade protocol based on the communication protocol and the target voltage grade.
The communication Protocol may be a SIF (Standard Image Format) communication Protocol or a TCP (Transmission Control Protocol) communication Protocol. Specifically, the voltage class protocol is generated by writing the target voltage class into an idle byte or each spare bit in a spare byte of the communication protocol. And, the data transmission rule of the communication protocol determines, for example, that the standby bit at the target voltage level is high, and the standby bits at the other voltage levels are low.
S103, sending data to an instrument display module according to the voltage level protocol, and switching the instrument display module to the working state of a sub-instrument assembly in the instrument display module, which is associated with the target voltage level, according to the voltage level protocol.
The data is digital signals, and the controller sends the data to the instrument display module according to the voltage level protocol, so that the instrument display module at the receiving end can decode the data according to the voltage level protocol, identify the target working voltage to be adjusted by a user, and adjust the current working voltage to the target working voltage.
For example, a user determines eight voltage levels of 36V, 48V, 60V, 64V, 72V, 80V, 84V and 96V, an international standard SIF communication protocol is utilized, an interface is universal and convenient, the level of data complies with a TTL (Transistor-Transistor Logic level) specification, the protocol is in a time sequence mode, one frame of data is transmitted at a time, the data comprises 65 bits, a start bit and 8 × 8 data bits, the idle state of a line is required to be changed to a low level after transmission is finished, a ninth byte of the protocol is a spare byte, and content can be added to the byte according to user requirements. The eight determined voltage levels are correspondingly written into each spare Bit of the ninth byte, preferably, in the ninth byte, 36V voltage level is written into Bit0, 48V voltage level is written into Bit1, 60V voltage level is written into Bit2, 64V voltage level is written into Bit3, 72V voltage level is written into Bit4, 80V voltage level is written into Bit5, 84V voltage level is written into Bit6, 96V voltage level is written into Bit7, a voltage level protocol is generated, and when a user wants to adjust the working voltage to 48V, namely the target voltage level is 48V, the data 01000000 is sent to the instrument display module through the controller according to the voltage level protocol.
According to the technical scheme of the embodiment of the invention, the voltage level function is added on the basis of the existing communication protocol to generate the voltage level protocol, and the controller sends data to the instrument display module according to the voltage level protocol, so that the problem that in the existing voltage conversion technology, voltage conversion needs to be carried out through a selection line, and the selection line is broken when being assembled or used by a user, and the like is solved, the safety and the stability of a machine are improved, and the user can use one instrument to adjust various voltages according to requirements.
Example two
Fig. 2 is a flowchart of a working voltage adjusting method according to a second embodiment of the present invention, where the second embodiment is applicable to a case where a current working voltage of a machine is not adapted to a rated voltage of a battery of the machine. As shown in fig. 2, the method may specifically include:
s201, receiving data sent by the controller according to the voltage level protocol, wherein the voltage level protocol is generated based on a communication protocol and a target voltage level to be switched.
The voltage class protocol may be generated by adding a target voltage class to each spare bit in a spare byte or a spare byte of an SIF communication protocol or a TCP communication protocol. And the instrument display module receives and controls data sent according to the data sending rule of the communication protocol. For example, the spare bit of the target voltage level is high, and the spare bits of the other voltage levels are low.
And S202, switching to the working state of the sub-meter assembly associated with the target voltage level.
The instrument display module can decode the data received based on the voltage level protocol to obtain a target voltage level, and controls the sub-instrument components related to the target voltage level to be in a working state, and other sub-instrument components to be in a pause state, so that the current working level voltage is adjusted to the target working voltage level.
According to the technical scheme of the embodiment of the invention, the instrument display module receives the data sent according to the voltage level protocol and adjusts the current working voltage to the target working voltage according to the voltage level protocol, so that the problem that the voltage conversion needs to be carried out through the selection line in the existing voltage conversion technology, the selection line is broken when being assembled or used by a user, and the like is solved, and the safety and the stability of the machine are improved.
On the basis of the technical scheme, before the working state of the sub-instrument assembly associated with the target voltage level is switched, the instrument display module also determines the target voltage level according to each spare bit potential of the spare byte in the voltage level protocol, and specifically, the instrument display module can decode data according to the protocol content and identify the target working voltage to be adjusted by a user. The sub-meter components of the meter display module can bear at least two of working voltages including user demand voltages.
The advantage of setting up like this has saved the instrument selection line and has reduced the instrument specification, and the communication is more reliable, has strengthened user experience.
