There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical solution of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
Fig. 1 is the flow chart of bus control method embodiment one of the invention, as shown in Figure 1, total line traffic control of the present embodiment
Method processed can specifically include following steps:
100, whether detection host computer is completed to power；
In the fields such as Industry Control, air-conditioning, the bus for communication can use time-sharing multiplexing technology, utilize two electricity
The mode of cable connection, realizes the energization and communication to the line control machine of slave computer.Specific control logic is to power on the master of rear host computer
Plate loads the DC voltage of 24V in bus, and the storage capacitor on the line control machine of slave computer starts to charge at this time, after a certain period of time
Storage capacitor charging on the line control machine of slave computer, which reaches voltage rating, can start to work normally, and then the mainboard of host computer is logical
It crosses control circuit and disconnects power supply, there is no supply voltage in bus at this time, can normally be communicated, the line traffic control of slave computer
Device charges again after the communication of one circulation, circuits sequentially by the corona discharge work of itself storage capacitor storage, from
And under smaller cost, so that bus is completed to power and is communicated.Wherein, bus is preferably RS485 communication bus.
It is red in practical application, the mainboard of host computer to the line control machine of slave computer complete after power supply due to bus capacitance etc. because
Number exists, and voltage will not decline immediately, the buses residual voltage such as needs can just carry out normal communication after ruing out of, therefore,
In this implementation, after host computer powers on, need to detect whether host computer completes power supply to the line control machine of slave computer.For example, if surveying
The electricity of storage capacitor on the line control machine of slave computer, and/or, the mainboard of host computer disconnects power supply by control circuit,
It can detecte host computer and complete power supply, otherwise, host computer does not complete power supply.
If 101, host computer completes power supply, detection bus whether there is residual voltage；
Due to, in bus residual voltage run out of the required time be it is unfixed, therefore, in order to avoid the time of setting
It is unreasonable, cause not communicated between host computer and slave computer, alternatively, the time of bus switch to communication mode is longer,
Influence communication efficiency.In the present embodiment, the time for specifically switching to communication mode is not reset, but due to remaining electricity in bus
It presses electricity and is necessarily required to the regular hour, so the present embodiment after detecting that host computer completes power supply, should not be detected directly total
Line whether there is residual voltage, but can set active detecting bus and whether there is the time of residual voltage.If host computer is complete
At power supply, it can actively go detection bus with the presence or absence of residual voltage, so as to according to detection after reaching the time of setting
As a result it determines whether control bus and enters normal communication mode.If host computer does not complete power supply, host computer is continued to test
Whether completion is powered.
, can be with after host computer completes power supply during a specific implementation, by bus switch to detecting communication mode,
And communication data can be sent to bus, after bus receives the communication data of transmission, corresponding feedback data can be generated, and
Feedback data is fed back.Wherein, if residual voltage is not present in bus, i.e. the communication channel of bus is clean, communication number
It will not be interfered according in the communication channel of bus, the feedback data i.e. communication data that bus generates.If bus exists
Residual voltage, i.e. the communication channel of bus be it is sordid, communication data will receive interference in the bus, and other in bus
Data carry out coupling and become fused data as feedback data.The communication data of the present embodiment is preferably a byte number
According to such as 0-0xff, that is, 0-255.
Causing communication data that can not be sent to the feedback of bus or bus there may be due to communication failure etc.
Data can not return, and therefore, in the present embodiment, after sending communication data to bus, can detecte and whether receive bus
Feedback data judges whether the feedback data of bus is consistent with communication data if receiving the feedback data of bus；If bus
Feedback data is consistent with communication data, and detecting bus, there is no residual voltages.That is, since there is no residual electricity for bus
Pressure, communication data will not be interfered in the communication channel of bus, so that the communication data issued is equal to received bus
Feedback data.If the feedback data of bus and communication data are inconsistent, it can determine that there are residual voltages for bus, that is to say, that
Since bus is there are residual voltage, communication data is interfered in the communication channel of bus, so that the communication data issued is not
Equal to the feedback data of received bus.
Since there are residual voltages for bus, so that bus cannot be introduced into normal communication mode, therefore, can be based on preset
Sending cycle sends communication data to bus again, after repeated detection, to determine bus with the presence or absence of residual voltage.
It should be noted that each interval time is ofer short duration, in the sending cycle of the present embodiment to avoid control bus
It is longer into the time needed for normal communication mode, communication efficiency is influenced, but interval time can not be too short every time, to avoid
Detect that bus is constantly present residual voltage.Specifically, the relatively reasonable time can be selected, as pre- based on practical experience
If sending cycle.
In addition, interval time may be the same or different every time.For example, the present embodiment be preferably every minor tick when
Between be it is different, can successively successively decrease.Such as, the time of detection is set as longer time for the first time, subsequent to detect every time
Time is relative to the preceding primary shortening regular hour.Specifically, it is needed in the present embodiment with least number, shortest time,
Bus is determined with the presence or absence of residual voltage, therefore, under the conditions of optimal, after sending communication data to bus for the first time
According to the feedback data of the communication data and bus determine bus with the presence or absence of residual voltage, if but first sent to bus it is logical
Bus is determined there are residual voltage after interrogating data, needs to send communication data to bus second.In practical application, bus it is big
Portion of residual voltage is discharged, and only fraction residual voltage is not discharged, needed for this fraction residual voltage is discharged
Time necessarily shorten, at this point, if according to first time detection time, to bus send communication data, necessarily will cause compared with
It is prolonged to wait, communication efficiency is reduced, therefore, in the present embodiment, the time of second of detection is less than to be detected for the first time
Time, similarly, the subsequent time detected every time is respectively less than the previous time.
If 102, residual voltage is not present in bus, control bus enters normal communication mode.
In the present embodiment, if detecting bus, there is no residual voltages, illustrate that the channel of bus is clean, will not be to logical
News data impact, and normal communication can be carried out, at this point it is possible to which control bus enters normal communication mode.
The executing subject of the bus control method of the embodiment of the present invention can be bus control device, the bus control device
It can specifically be integrated by software, such as the bus control device is specifically as follows an application or Embedded Operating System
In, the present invention is to this without being particularly limited to.Wherein, the bus control device of the present embodiment is preferably arranged in host computer.
The bus control method of the present embodiment, by detecting whether host computer is completed to power, if host computer completes power supply, inspection
Surveying bus whether there is residual voltage, if residual voltage is not present in bus, control bus enters normal communication mode, realize certainly
It adapts to detection host computer is completed to be spaced after power supply how long to control the bus and enter normal communication mode, avoids because setting is fixed
Time is inadequate, it will cause can not normal communication the phenomenon that, also avoid because setting the set time it is too long, communication efficiency is lower
Phenomenon.Using technical solution of the present invention, the switching mode reliability between the different working modes of bus can be improved, in turn
It improves communication success rate, improve communication efficiency.
Fig. 2 is the flow chart of bus control method embodiment two of the invention, as shown in Fig. 2, total line traffic control of the present embodiment
It is further more detailed that technical side's scheme of the invention is described on the basis of method embodiment shown in Fig. 1 processed.Such as
Shown in Fig. 2, the bus control method of the present embodiment can specifically include following steps:
200, whether detection host computer is completed to power；If so, step 201 is executed, if it is not, return step 200；
The realization process of the present embodiment is identical as the realization process of step 100 in above-described embodiment, please refers in detail above-mentioned
Correlation is recorded, and details are not described herein.
201, communication data is sent to bus；
For example, host computer can be with after completing power supply, by bus switch to detecting communication mode, in the case where detecting communication mode,
The equipment being connected with bus can send and receive bus transfer data.Specifically, communication data can be sent to bus, always
Line and feedback data backtracking by generation.
202, the timing duration after sending communication data is obtained；
Under normal conditions, in order to be confirmed whether there are communication failure, communicating circuit can all be preset when design
One overtime duration, if it exceeds this preset duration, is considered as time-out, was sentenced as preset duration, such as 30 seconds or 1 minute
It is set to communication failure, otherwise, if it is being more than this preset duration, is considered as not occurring communication failure.Therefore, the present embodiment
In, start timing after sending communication data, obtains sending the timing duration after communication data, and be acquired.
203, the size whether timing duration is less than preset duration is detected；If so, step 204 is executed, if it is not, executing step
Rapid 209；
After getting the timing duration after sending communication data, the big of the timing duration and preset duration can be compared
It is small, comparison result is obtained, to detect the size whether timing duration is less than preset duration, if comparison result indicates the timing
It is long to be less than preset duration, illustrate that bus is normal, communication failure is not present, execute step 204, otherwise, if comparison result expression should
Timing duration is more than or equal to preset duration, illustrates that bus is normal, and there are communication failures, executes step 210.
204, detect whether to receive the feedback data of bus；If so, step 205 is executed, if it is not, return step 203；
Causing communication data that can not be sent to the feedback of bus or bus there may be due to communication failure etc.
Data can not return, and therefore, in the present embodiment, after sending communication data to bus, can detecte and whether receive bus
Feedback data, if so, step 205 is executed, if it is not, return step 203.
205, judge whether the feedback data of bus is consistent with the communication data；If so, step 206 is executed, if it is not, returning
Step 201；
Wherein, if bus is not present residual voltage, i.e. the communication channel of bus be it is clean, communication data is logical bus
It will not be interfered in news channel, the feedback data i.e. communication data that bus generates.If there are residual voltages for bus, i.e., always
The communication channel of line be it is sordid, communication data will receive interference in the bus, be coupled with other data in bus
Become fused data as feedback data.Therefore, the feedback data of the communication data and bus can be compared, from
And judge whether the feedback data of bus is consistent with the communication data.For example, having sent a byte 0, bus to communication bus
The byte of return is 0, illustrates that the two is consistent, executes step 206, and the byte that bus returns is 1, then illustrates that the two is inconsistent, return
Step 201 is returned, so that whether the channel for continuing to detect bus is clean.
206, control bus enters normal communication mode；
If the feedback data of bus is consistent with the communication data, illustrate that the channel of bus is clean, it will not be to communication number
According to impacting, normal communication can be carried out, at this point it is possible to which control bus enters normal communication mode.Host computer and slave computer
Between can switch to again charge mode, and so on normal communication, and after completing a communication cycle.
207, the transmission times that communication data is sent to bus is counted；
In practical applications, although the timing duration after sending communication data is less than or equal to preset duration,
During the timing duration, if always detecting bus, there are residual voltages, and illustrating bus, there are signal interference failures, for example, nothing
The failure that method is discharged.Therefore, in the present embodiment, if judging, the feedback data of bus and the communication data are inconsistent,
Need to count the transmission times that communication data is sent to bus.
208, judge whether the transmission times that communication data is sent to bus is greater than preset threshold, if so, executing step
209, if it is not, return step 201；
It is obtaining after the transmission times that bus sends communication data, it can be determined that the transmission of communication data is sent to bus
Whether number is greater than preset threshold, if so, illustrating that the residual voltage of bus possibly can not discharge, causes to interfere signal,
So that feedback data is inconsistent with communication data, step 209 is executed, otherwise, preset sending cycle is based on, is sent out again to bus
Communication data is sent, with return step 201.
209, determining bus, there are signal interference failures；
If judging, the transmission times that communication data is sent to bus is greater than preset threshold, can determine that there are signals for bus
Failure is interfered, and corresponding prompt information can be exported, to prompt related personnel to safeguard.
210, determine that there are communication failures for bus.
If timing duration is more than or equal to preset duration, determining bus, there are communication failures, and can export corresponding
Prompt information, to prompt related personnel to safeguard.
The bus control method of the present embodiment, realize self-adapting detecting host computer complete to be spaced after power supply how long control it is total
Line enters normal communication mode, avoid because setting the set time it is inadequate, it will cause can not normal communication the phenomenon that, also avoid
Because the setting set time is too long, communication efficiency lower phenomenon, while can be with, detect bus with the presence or absence of signal interference therefore
Barrier, communication failure etc., to notify related personnel to safeguard in time.Using technical solution of the present invention, bus can be improved
Different working modes between switching mode reliability, and then improve communication success rate, improve communication efficiency.
