Detailed Description
The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.
The invention provides a time-triggered Ethernet solidification point parallel monitoring device, which comprises a monitoring control unit 1, wherein the monitoring control unit 1 is connected with a plurality of solidification point monitoring units 4; the solidification point monitoring unit 4 sends a corresponding monitoring unit state output 5 to the monitoring control unit 1, the monitoring control unit 1 updates a corresponding monitoring unit state 3 through the monitoring unit state output 5, and the group state module 2 is a set of all monitoring unit states 3; the monitoring control unit 1 sends a monitoring unit start signal to the curing point monitoring unit 4.
As shown in fig. 2, the solidification point monitoring unit 4 includes a comparison unit 15, a clock selection unit 11 connected to the comparison unit 15, and a data storage unit 14.
The curing point monitoring unit 4 has a function of independently monitoring the curing points, can track and compare the relationship between the current local clock counting value and the curing points after being started, and provides an identification signal when the local clock is consistent with the curing points. The cure site monitoring unit 4 needs to complete clock selection and cure site comparison. Firstly, the curing point monitoring unit 4 can be started or closed through an external enable/disable switch, and provides a busy state indication to the outside during working and provides an idle state indication to the outside during non-working; secondly, selecting a local clock count value 9 in a synchronous state or a local clock count value 10 in an asynchronous state by using a local synchronous/asynchronous state 8 to finish the selection of the monitoring clock; and finally, storing the curing point numerical value 13 and the curing point type 12 in a data storage unit 14 in the unit, comparing the curing point numerical value with the monitoring clock in real time, and outputting a curing effective signal corresponding to the curing point type when the curing point numerical value and the curing point type are consistent.
When a new curing point appears, the curing point monitoring unit 4 may be in a busy state, and cannot monitor the curing point, so that the invention designs a plurality of monitoring units in the node to realize parallel monitoring of a plurality of curing points. The idle monitoring unit is started to monitor a new curing point, and the busy monitoring unit needs to be protected to ensure that the working state and the monitored curing point are not tampered; after the curing point monitoring unit 4 completes the work, it needs to be released for the next monitoring work.
The solidification point monitoring unit 4 realizes the management of a state management table and a retrieval mode through the group state module 2; the method specifically comprises the following steps: when a new solidification point occurs, an 'idle' monitoring unit which can be served for the new solidification point is searched through the retrieval of the state management table. The state management table firstly numbers each curing point monitoring unit 4, records and updates the current state of the curing point monitoring unit corresponding to each number, namely 'busy' or 'idle', and then defines a group by four monitoring units from small to large according to the number, if the group contains one or more 'idle' monitoring units, the group state is marked as 'idle', and if the monitoring units in the group are 'busy', the group state is marked as 'busy'. The retrieval mode adopts a two-stage retrieval mode, wherein the first-stage retrieval is group retrieval, when the group state is busy, the next group is retrieved, if the group state is idle, the second-stage retrieval, namely unit retrieval, is carried out on the group, the idle unit with the minimum number is started, a monitoring task is carried out, and the busy unit is ensured not to be interrupted. The method effectively reduces the hardware retrieval overhead.
In the Ethernet, the number of the solid state point monitoring units 4 depends on the maximum number of PCFs existing in the TTE network in one full-network PCF interaction, and for synchronous compression nodes (CM for short), the maximum number of synchronous frames is related to the number of synchronous main nodes (SM for short) in the network; for synchronization master nodes and synchronization client nodes (SC for short), the maximum number of synchronization frames is related to the number of SMs in the network and the network redundancy pattern.
The invention also provides a parallel monitoring method of the time-triggered Ethernet curing points, which comprises the steps of monitoring a plurality of curing points simultaneously, providing an identification signal when the local clock count value is consistent with the curing points by comparing the local clock count value with the curing points, and then outputting a curing effective signal corresponding to the type of the curing points; wherein comparing the local clock count value to the cure points comprises selecting a synchronous/asynchronous clock count value and then comparing the number of cure points to the clock count value.
And obtaining the solidification points with idle states by a two-stage retrieval mode for the states of the plurality of solidification points.
The working principle of the parallel monitoring device for the time-triggered Ethernet solidification point is as follows: firstly, the monitoring control unit 1 updates the monitoring unit state 3 according to the state information of the monitoring unit state output 5, and the group state module 2 updates according to the state of the monitoring unit state 3; when a new curing point monitoring requirement exists, the monitoring control unit 1 searches the group state module 2 until a group state module with an idle state is searched, then searches the monitoring unit state 3 corresponding to the group state module, acquires the curing point monitoring unit 4 with the minimum number and in the idle state, finishes the search, and then starts the searched curing point monitoring unit 4 through the monitoring unit starting signal 6.
When the monitoring control unit 1 finishes the starting or the prohibition of the curing point monitoring unit 4 through the monitoring unit starting signal 6, the clock selection unit 11 selects a local clock count value 9 in a synchronous state or a local clock count value 10 in an asynchronous state as a local clock according to the local synchronous/asynchronous state 8; the data storage unit 14 completes temporary storage of the type 12 of the curing point and the numerical value 13 of the curing point, and meanwhile, the curing point is protected in the monitoring process to prevent the curing point from being tampered; the comparison unit 15 performs comparison of the local clock and the curing point, and outputs curing point valid information 16 matching the curing point when the two coincide. In the time from the start of the curing point monitoring unit 4 to the completion of the curing point monitoring, the state output 5 of the monitoring unit corresponding to the curing point monitoring unit 4 is in a busy state, and after the curing point monitoring is completed, the state output 5 of the monitoring unit is in an idle state.
The technical scheme of the invention describes the logic design of the parallel monitoring unit of the solidification point by using a Verilog HDL language, and completes logic synthesis and layout wiring; the scheme is used in the clock synchronization of the time-triggered Ethernet end system and the switch, and the networking is performed for functional test, and the test result shows that the method has good implementability, can realize the parallel monitoring of multiple solidification points, and has nanosecond monitoring precision and sub-microsecond network synchronization precision.
