Abstract
The present invention discloses a hot push-pull method supporting a UTOPIA bus device. A main device module poll bus connects a slave device module to conduct communication, wherein, the slave device module includes a slave device, a drive part, and socket connectors. The method includes the following steps: when detecting that the slave device is electrified, the drive part which controls the slave device takes high resistance state; and when the slave device is stabilized, then the drive part of the slave device can be opened. The method of the present invention solves the problem that when the UTOPIA bus is used as a back board bus, the process of the hot push-pull can disturb the ongoing data, and can influence the communication of the main device and other slave devices.
Description
Technical field
The present invention relates to a kind of support UTOPIA (Universal Test ﹠amp; Operations PHYInterface for ATM, the universal test of ATM and operating physical interface) method of bus equipment hot swap, specifically, and at utopia bus during as core bus, a kind of method of supporting the utopia bus equipment hot swap.
Background technology
The UTOPIALEVEL2 bus can connect a plurality of equipment as the carrying bus of ATM cell, and a plurality of equipment can a shared cover bus carry out exchanges data, in mutual process, as the poll of main equipment initiation for slave unit, and then finish the mutual of data.Along with the development of DSL technology, compact apparatus is in the consideration of cost, with utopia bus when as core bus, for the ease of the system that safeguards flexibly, need to support hot plug.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method of the UTOPIA of support hot plug, to solve at utopia bus during as core bus, need to support hot plug, produce the problem of disturbing but in the process of hot plug, can bring for ongoing data.
In order to address the above problem, the invention provides a kind of method of supporting the utopia bus equipment hot swap, the slave unit module that connects on the main equipment module poll bus, and then communicate, wherein, described slave unit module comprises slave unit and driving element and connector, and its described method comprises the steps: that the driving element that the hot plug control module is controlled described slave unit is high-impedance state when detecting slave unit and power on; After treating that slave unit is stable, described hot plug control module is opened the driving element of described slave unit again.
Method of the present invention, it further comprises: when detecting described slave unit when bus is pulled up, the driving element that described hot plug control module is controlled described slave unit is high-impedance state.
Method of the present invention, in the contact pin of its described slave unit connector, the length of the contact pin relevant with the power supply power supply, the length of being longer than the contact pin relevant with described driving element makes the described contact pin relevant with power supply contact with utopia bus prior to the described contact pin relevant with driving element; Described main equipment module comprises main equipment and driving element and connector.
Mutual by with described main equipment of method of the present invention, described hot plug control module controlled the driving element of described slave unit.
Method of the present invention has solved at utopia bus during as core bus, can bring in the process of hot plug to produce for ongoing data and disturb, and influences the communication issue of main equipment and other slave units.
Description of drawings
Fig. 1 is the composition Organization Chart of the described support utopia bus of embodiment of the invention equipment hot swap;
Fig. 2 is the structural drawing of the slave unit module in the described support utopia bus of the embodiment of the invention equipment hot swap.
Embodiment
Below in conjunction with accompanying drawing, the described technical scheme of the embodiment of the invention is described in further detail.
As shown in Figure 1, the described a kind of method of supporting the utopia bus equipment hot swap of the embodiment of the invention comprises device: main equipment module 101, hot plug control module 102 and slave unit module 103.
Wherein, main equipment module 101 comprises main equipment and driving element and the connector of supporting hot plug.Physical damage when its driving element prevents that hot plug own and other modules from carrying out hot plug.
Hot plug control module 102, mutual by with main equipment provides for main equipment control function for the driving element of slave unit in polling procedure.
As shown in Figure 2, the slave unit module in the described support utopia bus of the embodiment of the invention equipment hot swap comprises slave unit 203 and driving element 202 and the connector 201 of supporting hot plug.
Wherein, in the contact pin of described connector 201, the length of the contact pin relevant with power supply power supply, the length of being longer than the contact pin relevant with described driving element 202 makes the described contact pin relevant with power supply contact with utopia bus prior to described and driving element 202 relevant contact pins.
The described a kind of method of supporting the utopia bus equipment hot swap of the embodiment of the invention, comprise step: main equipment module 101 is as main equipment, the slave unit module 103 that connects on the responsible poll utopia bus, and then communicate, at main equipment with when some slave units are communicated by letter, if other slave unit module 103 hot plugs arranged this time and be connected on the utopia bus, further step is, in detecting the process that slave unit powers on, need slave unit module 103 the support hot plug driving element or enable to drive and be high-impedance state, because the instability of power up, so the driving element of slave unit is high-impedance state, after treating that slave unit is stable, open described driving element.Wherein, driving element and utopia bus are unconnected, can use the control realization for the power supply of connector.In the process under detecting the slave unit hot drawing, need also to guarantee that by the control of hot plug control module 102 and power supply driving element is a high-impedance state that not influence main equipment in the process of slave unit hot plug unaffected with communicating by letter of other slave units thereby finish.
Above-mentioned embodiment describes the present invention with preferred embodiment, should not be regarded as limitation of the scope of the invention.Equally, according to the description of technical scheme of the present invention and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of claim of the present invention.
Claims (4)
1, a kind of method of supporting the utopia bus equipment hot swap, the slave unit module that connects on the main equipment module poll bus, and then communicate, wherein, described slave unit module comprises slave unit and driving element and connector, it is characterized in that described method comprises the steps: that the driving element that the hot plug control module is controlled described slave unit is high-impedance state when detecting slave unit and power on; After treating that slave unit is stable, described hot plug control module is opened the driving element of described slave unit again.
2, the method for claim 1 is characterized in that, further comprises: when detecting described slave unit and pull up, the driving element that described hot plug control module is controlled described slave unit is high-impedance state.
3, the method for claim 1, it is characterized in that, in the contact pin of described slave unit connector, the length of the contact pin relevant with the power supply power supply, be longer than the length of the contact pin relevant, make the described contact pin relevant contact with utopia bus prior to the described contact pin relevant with driving element with power supply with described driving element.
