Description
Technical Field
The invention relates to the field of triggers, in particular to a trigger, and a method and a device for determining an output state of the trigger.
Background
At present, thermal power generating units are continuously developed towards the directions of high capacity, high parameter and complexity, distributed control system DCS hardware configuration is required to be continuously improved, and the reliability requirement on a matched DCS software platform is higher and higher. The DCS logic configuration of the current thermal power plant is carried out at an engineer station. And (3) calling a logic module in the DCS database at the site by an engineer according to the control requirement of the field system, performing soft connection on the module to complete a configuration scheme, and finally downloading the logic into each DCS controller. A conventional RS flip-flop module is in the DCS database at the present stage, fig. 1 is a schematic diagram of a flip-flop module according to the prior art, and as shown in fig. 1, the conventional reset-set flip-flop module has two input terminals: a set input, a reset input, and an output, the truth table of which is shown in table 1:
TABLE 1
| S | R | OUT |
| 0 | O | Is not changed |
| 1 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 1 | 0 |
The above-described conventional reset-set flip-flop modules are widely used in various logic schemes, such as: equipment trip first-out logic, MFT protection logic, boiler ignition memory logic, and the like.
The reset set trigger module is used in important interlocking protection, and particularly has great potential safety hazard under the condition that the module is placed at the tail end of a certain protection logic, and the output end of the module is directly used as protection output to link other equipment. Fig. 2 is a SAMA diagram of protection logic of a trigger module according to the prior art, and as shown in fig. 2, when a unit is operating normally, there are a plurality of protection conditions, for example, protection condition 1, protection condition 2, protection condition 3 … …, protection condition n, and reset condition, where the protection conditions except the reset condition are all connected to an or module, and when a field device triggering protection condition 1 fails, a thermal operator may force an output port OUT (at this time, the value is "0") of the RS trigger module in the protection logic to be "0" in order to prevent protection signal false triggering during device failure processing when the protection condition 1 is mistakenly operated by the thermal operator. When the thermal staff really triggers the protection condition 1 in the field fault processing process, namely the protection signal sends a pulse to the set end of the RS trigger module once, the RS has the latching characteristic, and the value of the reset end of the module is 0, the actual value of the output port OUT of the RS trigger module is 1. And because the port is in a forced state, if the logic is checked on line, a thermal operator cannot check the actual value of the port. After the work is finished, the thermal staff can forcibly restore the output OUT, namely the output OUT is restored to an actual value from a forced value of '0', the output port is changed to 1 at the moment, and the protection signal can be output to cause misoperation.
Aiming at the problem that the trigger in the related technology has potential safety hazard in interlocking protection, an effective solution is not provided at present.

In order to enable the operator to intuitively know the value corresponding to the current output state of the first output terminal, as an optional embodiment of the present invention, the flip-flop may further include: and the display module is connected with the current value port and used for displaying the numerical value corresponding to the output signal.
In addition, as an optional embodiment of the present invention, the flip-flop may further include: and the voice module is connected with the current value port and used for playing the numerical value corresponding to the output signal.
As an alternative embodiment of the present invention, the first input terminal may include: the device comprises a set input end and a reset input end, wherein the set input end is connected with at least one set switch and used for receiving at least one switching value signal transmitted by at least one set switch, and the reset input end is connected with a reset switch and used for receiving the reset switching value signal transmitted by the reset switch.

When a worker really triggers the protection condition 1 in the process of processing the fault on site, namely a protection signal sends a pulse to the set input end of the trigger once, the value of the reset input end is 0 again due to the characteristic of latching of the trigger, and the actual value of the original output end of the trigger is 1. And because the original trigger output end is in a forced state, a worker can directly judge the actual value of the original trigger output end by looking up the numerical value of the current value output end (namely, a PV end), directly reset the output value of the current value output end and the output value of the output end to be 0 through the reset input end, and then release the original trigger output end, so that the protection instruction is prevented from being sent by mistake.
