The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As described in the background art, in the existing communication manner, in order to realize resource sharing between different devices, a unified communication protocol format is first required between the devices, and it is common practice to add a protocol conversion device, where the protocol conversion device needs to follow the protocol format and rate of the access device, and the format and rate of the accessed device. Although resource sharing can be achieved by this protocol conversion apparatus, the same protocol conversion apparatus can be adapted to only one device, and when a new device is introduced, a new protocol conversion apparatus needs to be replaced, which would require a large investment in cost.
In order to solve the above problem of resource sharing without adding additional cost, the embodiment of the application provides a communication method applied to a first device, wherein the first device and a second device communicate based on a preset data frame format. The first device and the second device may be a PC or various mobile intelligent terminals, and the preset data frame format is a format requirement of the first device and the second device for the transmitted data frame according to a communication protocol, where the preset data frame format is generally a format of frame header+data information.
In one embodiment, the present application provides a communication method applied to a first device. As shown in fig. 1, the communication method includes the following steps:
step S10: and receiving a data frame sent by the second device, wherein the frame head of the data frame comprises a synchronous interval field.
The second device sends data to the first device according to a preset data frame format, and the first device receives a data frame sent by the second device, wherein a frame header of the data frame comprises a synchronous interval field, and the synchronous interval field is matched with the data transmission rate of the second device. The synchronization interval field may be matched with the data transmission rate of the second device in various manners, for example, the synchronization interval field may represent width information of a preset level (i.e., duration of the preset level), the width information of the preset level and length information corresponding to the preset level (i.e., number of bits corresponding to the preset level) are matched with the data transmission rate of the second device, or the synchronization interval field may be matched with the data transmission rate of the second device in other manners, which are not listed herein.
In addition, the frame header of the data frame further comprises a synchronous field, the synchronous field is composed of commands, the commands can be divided into an operation state, an operation control and the like, the data information part in the data frame specifically comprises a data field and a check field, the data field can comprise equipment time, historical data, control data, state data, upgrading data and the like, and the check field can comprise accumulation and check, exclusive or check, CRC8 check, CRC16 check and other check modes.
Step S30: the data transmission rate of the second device is determined based on the synchronization interval field.
After the first device receives the data frame sent by the second device, the data transmission rate of the second device can be determined according to the synchronous interval field in the frame head of the data frame. Since the sync interval field is matched with the data transmission rate of the second device, when the first device acquires the data frame of the second device, it can acquire the data transmission rate of the second device matched with the sync interval field through the sync interval field in the data frame.
Step S50: and adjusting the data transmission rate of the first device according to the data transmission rate of the second device.
When the first device determines the data transmission rate of the second device, the first device adjusts the data transmission rate of the first device according to the data transmission rate of the second device so that the data transmission rate of the first device is matched with the data transmission rate of the second device, and further data information transmitted by the second device is successfully received, so that resource sharing is realized.
The communication method is applied to the first equipment, the first equipment and the second equipment communicate based on a preset data frame format, and after the first equipment receives a data frame sent by the second equipment, the data transmission rate of the second equipment is firstly determined according to a synchronous interval field contained in a data frame header, and then the data transmission rate of the first equipment is adjusted according to the data transmission rate of the second equipment. Therefore, the data transmission rate of the second device can be determined only according to the synchronous interval field in the frame header of the data frame sent by the second device without adding a protocol conversion device or changing the protocol format of the second device, and the data transmission rate of the first device is further adjusted, so that the data transmission rates of the first device and the second device are matched, and resource sharing among different devices is realized under the condition of not increasing extra cost.
In one embodiment, the sync interval field is used to characterize the low level width, which refers to the duration of the low level. As shown in fig. 2, step S30, i.e. the step of determining the data transmission rate of the second device from the synchronization interval field, comprises the steps of:
step S301: the low level width is determined from the sync interval field.
Since the synchronization interval field characterizes the low level width, after the first device acquires the data frame transmitted by the second device, the low level width, i.e. the duration of the low level, may be determined first by the synchronization interval field. The determination of the low level width may be implemented in combination with an interrupt function, a timer function, or the like.
Step S302: and determining the data transmission rate of the second device according to the low level width and the preset low level length.
The preset low level length refers to a bit number corresponding to the preset low level. Before the first device and the second device communicate, both devices should have a predetermined low-level length and the predetermined low-level length is stored in both the first device and the second device, or both devices have the same low-level length according to the protocol to which they are compliant. When the first device obtains the low level width according to the synchronization interval field, the data transmission rate of the second device can be determined according to the low level width and the preset low level length stored in the first device. It should be noted that, the preset low level length and low level width are set in combination with the data transmission rate of the second device and the data processing rate of the first device, so that the data transmission rate error of the finally determined second device is smaller, and meanwhile, excessive system resources are avoided being consumed.
In one embodiment, as shown in fig. 3, step S301, i.e., the step of determining the low level width according to the synchronization interval field, includes the steps of:
S3011: the first falling edge in the data frame is captured. Specifically, when the first device does not communicate data with the second device, the data receiving port of the first device may be set to a high level, and when a data frame sent by the second device is received, since the synchronization interval field is located at the frame head of the data frame and is at a low level, the first device captures the first falling edge in the data frame, that is, captures the initial time of the synchronization interval field.
S3012: the first rising edge in the data frame is captured. The first rising edge in the data frame, the end of the sync interval field, is captured.
Specifically, the data frame may be in a format of a synchronization interval field+a synchronization field+a data field+a check field, where the synchronization interval field is located at an initial position of the data frame and is a continuous low level signal, the synchronization field is located after the synchronization interval field and is a high level signal of an interval, and an initial level of the synchronization field is a high level. The first rising edge in the data frame, the end time of the captured sync interval field, is captured, as well as the initial time of capturing the sync field.
S3013: the low level width is determined from the time difference between the first falling edge and the first rising edge.
When the first falling edge and the first rising edge in the data frame are captured, the time difference between the first falling edge and the first rising edge, namely the low level width, can be obtained.
The above-mentioned manner of capturing the first falling edge and the first rising edge in the data frame may be implemented by a capturing function port, where the capturing function port may be a port having both a GPIO (General-purpose input/output) function and a PWM (pulse width modulation) wave acquisition function, and may perform edge detection, and the capturing port is connected to the data receiving port.
The above edge detection may also be achieved by an interrupt port, which is typically provided with an edge detector to trigger the generation of an interrupt event upon detection of a rising or falling edge. Therefore, the interrupt port can be connected to the data receiving port so that the arrival of a falling edge or a rising edge is confirmed according to the interrupt signal generated by the interrupt port when a data frame is received.
The mode of determining the low level width by capturing the edges is higher in accuracy, and is beneficial to improving the internal calculation speed and improving the overall data transmission efficiency.
As a modification, as shown in fig. 4, step S301, i.e., the step of determining the low level width from the synchronization interval field, includes the steps of:
s3014: the low level in the data frame is detected and the timing is started when the first low level in the data frame occurs and stopped when the first low level ends.
In practical application, high and low level detection can be realized through a common I/O port. The timer is started to count when the first low level in the data frame starts, and the timer is controlled to stop counting when the first high level in the data frame appears, i.e. when the first low level ends.
S3015: the low level width is determined based on the duration of the timer. The above-mentioned time duration of the timer can be used as the low level width.
Of course, the above steps may be replaced by: once when the first low level appears, the first high level appears, i.e. the first low level ends, and the time is counted again, and the time difference of the two times of counting is taken as the low level width.
The low-level width determining mode does not need to depend on a port with a capturing function, and can be determined only by a timer, so that the cost is low, and the implementation is simple and convenient.
The above methods for determining the low level width are applicable to the present application, and can be selected according to practical requirements in practical application.
In one embodiment, step S302, that is, the step of determining the data transmission rate of the second device according to the low level width and the preset low level length, is:
Determining the data transmission rate of the second equipment according to a preset relation between the data transmission rate, the low level width and the preset low level length;
Wherein, the preset relation is:
Wherein BAUD is a data transmission rate, n is a preset low level length, and T is a low level width.
Specifically, the preset low level length is a preset number of bits, for example, 13bits, and the low level width is a duration of the low level, for example, 1.5ms. When the first device obtains the low level width, the data transmission rate of the second device is 8666bps by combining the low level length stored in the first device and the preset relation. Since there are several kinds of common data transmission rates fixed, including 9600bps, 19200bps, 115200bps, and the like. When the data transmission rate is calculated to be 8666bps, it can be considered to fall within an error range of 9600bps, that is, the first device side can determine that the data transmission rate of the second device is 9600bps.
In one embodiment, step S50, i.e. the step of adjusting the data transmission rate of the first device according to the data transmission rate of the second device, comprises the steps of:
s501: when the data transmission rate of the first device is inconsistent with the data transmission rate of the second device, the data transmission rate of the first device is adjusted so that the data transmission rate of the first device is consistent with the data transmission rate of the second device.
After the first equipment acquires the data transmission rate of the second equipment, the data transmission rate of the first equipment is compared with the data transmission rate of the second equipment, if the data transmission rate of the first equipment is inconsistent with the data transmission rate of the second equipment, the data transmission rate of the first equipment is consistent with the data transmission rate of the second equipment, and if the data transmission rate of the first equipment is consistent with the data transmission rate of the second equipment, the data transmission rate of the first equipment is not required to be adjusted. The adjusting the data transmission rate of the first device is specifically adjusting the register configuration of the first device, and the data transmission rate of the first device is adjusted to be consistent with the data transmission rate of the second device.
In one embodiment, as shown in fig. 5, step S50, that is, after the step of adjusting the data transmission rate of the first device according to the data transmission rate of the second device, the communication method provided by the embodiment of the present application further includes the following steps:
S70: and carrying out data transmission with the second equipment according to the adjusted data transmission rate.
When the data transmission rate of the first device is adjusted, the first device can perform data transmission with the second device according to the adjusted data transmission rate. Since the data transmission rates of the first device and the second device are already adjusted to be consistent, resource sharing can be smoothly realized.
In one embodiment, as shown in fig. 6, step S70, that is, the step of transmitting data with the second device according to the adjusted data transmission rate, includes the following steps:
S701: and receiving a first measurement parameter based on the target object, which is sent by the second equipment, according to the adjusted data transmission rate.
After the first device adjusts its own data transmission rate according to the data transmission rate of the second device, the first device can receive and analyze the data frame sent by the second device. In one embodiment, the second device sends to the first device a first measurement parameter based on a target object, which may be a person or animal, or the like, and the first measurement parameter may be an impedance measurement or heart rate measurement, or the like, based on the target object.
The communication method provided in this embodiment further includes the following steps:
s702: a second measurement parameter based on the target object is acquired. The second measurement parameter may be an impedance measurement value or a heart rate measurement value based on the target object, and the second measurement parameter is obtained by measuring by a different device from the first measurement parameter.
S703: at least one physiological parameter of the target object is determined from the first measurement parameter and the second measurement parameter.
Wherein at least one of the first measured parameter and the second measured parameter comprises a bioimpedance value of the target subject, and the physiological parameter comprises at least one of a body composition parameter and a heart rate parameter of the target subject. For example, the first measurement parameter is a measurement value of impedance of two feet of a human body, the second measurement parameter is a measurement value of heart rate of the human body, and the physiological parameters determined according to the first measurement parameter and the second measurement parameter are a human body component, heart rate row and the like. For another example, the first measurement parameter is a measured value of impedance of both hands of the human body, the second measurement parameter is a measured value of impedance of both feet of the human body, and the physiological parameter determined according to the first measurement parameter and the second measurement parameter is a component of the human body. The human body composition calculated by combining the two-foot impedance measurement value and the two-hand impedance measurement value is more accurate and comprehensive than the human body composition calculated by singly using the two-hand or two-foot impedance measurement value.
