Latch counting trigger system
A latch counting triggering system is shown in fig. 6, and comprises a position information acquisition unit, a latch function module, a trigger function module and a trigger execution unit which are in telecommunication connection.
The position information acquisition unit adopts a non-contact photoelectric or magnetoelectric sensor and inputs data to the latching function module. Further, in one example, the position information acquisition unit transmits the acquired information to the latching function module through a receiving port of a 64-bit high-speed encoder.
The latching function module comprises a conventional latching function unit, an offset triggering latching unit and a latching filtering function unit, when the offset distance between signals input by the position information acquisition unit is larger than a set safety distance, a newly input signal is latched to be effective, and the latching function is triggered after the signal input by the position information acquisition unit reaches the effective range of the latching filtering function unit.
Furthermore, the latching function module is provided with a plurality of paths of latching inputs and triggering outputs; each path of latch is provided with an independent FIFO buffer area, and each trigger channel is provided with a trigger queue buffer area.

The whole system is exemplarily designed to receive 1 path of encoder signals, the highest 64-bit encoder technology can trigger 16 camera workstations to work at most, the encoder values can be recorded at the moment of receiving the feeding photoelectric signals by adopting offset triggering, and the triggering is carried out after the encoder rotates a set distance, so that the use of a set type is more convenient, and a panel schematic diagram is shown in fig. 7, and specific examples are described as follows.
1 latch functional module
1.1 conventional latch function cell
1) Encoder latching: the system has 4-way latch input, each way latch has independent FIFO buffer area (dynamic flyswatting buffer area), and each buffer area has 511 spaces. Due to the architectural nature of the FIFO, each time a latched datum is acquired, that datum is removed from the FIFO.
Referring to fig. 7 and 8, the latch pin S is related to LTC pin, and 1 latch pin S is responsible for the common terminal of the following 4 LTCs, and when a 24V potential difference is formed between the common terminal S and LTC pin of the latch signal, the encoder position is recorded instantaneously and stored in the FIFO of the corresponding latch channel. The common terminal can be connected with 24V, the LTC pin is NPN, and S is connected with 0V and is PNP.
2) High-speed input counting: the pins are still 4 sets of LTC + -pins, each path of LTC has a counter, and when a 24V potential difference is generated between the pins, the system will capture the instant of rising edge and count the value of + 1.
1.2 offset triggered latch unit
The pins are still 4 sets of LTC + -pins, each LTC has a counter, and when a 24V potential difference is generated between the pins, the system will capture the instant of the rising edge and the value of the counter is + 1.
Referring to fig. 9, when the offset is latched with a moment of capturing the signal, the current encoder value is recorded, and then when the encoder moves by the "offset distance", the designated channel outputs a trigger signal. The offset distance here is at least 1 pulse distance.
Meanwhile, the offset triggered latch unit provides a product space protection function, specifically, referring to fig. 10, when offset latch is used, a guard distance of a space is latched. When the offset latch is triggered, if a signal is input again within the protection distance, the signal is considered as a false trigger signal and is ignored. After the offset latch 0 triggers, the offset latch 1 triggers within the safe distance, which ignores the signal, and after the safe distance has passed, the offset latch 2 triggers, which takes effect.
1.3 latch filter function unit
The latch filtering is to the filtering of 4 way LTC pins, and the range of setting is 1000 ~ 9999990ns, and the signal that has reached the filtering time at the waveform width can be considered as valid signal, just can trigger corresponding latch function.
2. Latching functional module
Referring to fig. 7 and fig. 11, the system has 16 trigger outputs, each trigger channel has a trigger queue buffer, and for different trigger functions, the data structure in the buffers may also change correspondingly, and a single buffer may store 255 data.
2.1 kick the trigger unit
The kick trigger is distinguished from an offset trigger, which requires an offset latch to provide a reference position, but unlike the kick trigger, this mode only requires that the trigger position be pushed into a buffer of the corresponding trigger channel, and when the encoder is operated to the trigger position, the corresponding channel triggers a pulse signal. Referring to fig. 12, for kick triggering, the data in the buffer area is sorted.
2.2 offset trigger cell
Referring to fig. 9, as with the offset triggered latch unit of 1.2, the offset triggering of the offset triggered unit needs to be used simultaneously with the offset latching, and the offset triggering is triggered by taking the offset latching as a reference. When the offset latch latches a signal, the current encoder value is recorded at the moment, and then after the offset distance, the corresponding trigger channel outputs a signal.
2.3 output guard interval Unit
After a trigger outputs a pulse, if the distance from the next trigger position to the current trigger position is less than the guard interval, the trigger action is ignored. The trigger will not be effective until the distance from the last trigger position is greater than the guard interval. Referring to fig. 13, after triggering 0, there are trigger 1 and trigger 2 data within the safe distance, trigger 1 and trigger 2 will be ignored, and only trigger 3 outside the safe distance will be output, where the safe distance can be infinitely close to 0, but cannot be set to 0.
2.4 encoder speed Compensation Unit
The compensation function of the module can be used when the trigger output needs to be triggered by real-time compensation (advancing or following a certain pulse) according to the speed of the encoder. The module can calculate the speed of the encoder in real time according to a set calculation period, and compensate based on a reference speed-offset set according to requirements, and can set two directions of early triggering or late triggering.
Referring to fig. 14, a reference curve can be obtained according to the set offset-speed value, the speed of the encoder is obtained through module calculation, and the offset value at the current speed can be obtained through calculation by substituting the speed into the curve. Before the module outputs a pulse signal, the module will be triggered after adding offset to the original trigger position. Thereby implementing the compensation function.
3 position information acquisition unit
The position information acquisition unit, i.e. the encoder input: referring to the EA +, EA-, EB-and EB + pin areas of FIG. 7, the receiving port of the high speed encoder of the latch count trigger system supports 5V differential signals, with the highest receiving frequency of 4 Mhz. The encoder input is the signal source for latching and triggering in the core function.
4. Net mouth
Referring to fig. 7, a LINK indicator light LINK LED of each network card is above the network port and is green. If a plurality of modules are required to be used simultaneously, the modules can be connected in series by using a network cable.
Description of the application: for example, the device and the system can be applied to the streamline of detection, labeling, processing and the like of power batteries, semiconductor silicon wafers and the like.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
