step S110: the first starting signal sent by the remote control module 100 is obtained and self-maintained.
It should be understood that the remote control module 100 may set a button to send a general operation command such as a first start signal through a manual control button, or may automatically send a start operation command such as a first start signal at a set interval. The first starting signal is one of the total operation instructions, and there may be a second starting signal, a third starting signal, and the like, where each starting signal is used to correspond to different test requirements, for example, the test requirements may be requirements for different smoke amounts required by the fire detector of the nuclear power plant during testing.
Step S120: a first activation signal is sent to the spray module 600.
It should be understood that the first activation signal may be sent to the spray module 600 in a wired or wireless manner, such as serial communication, WIFI or bluetooth.
Step S130: whether a starting feedback signal fed back by the spraying module 600 is received or not is detected.
It should be understood that the detection of whether the start feedback signal fed back by the spraying module 600 is received is to detect whether the spraying module 600 is normally started, and in other embodiments, whether the spraying module 600 is started may also be determined by detecting whether the operating parameter of the spraying module 600 changes, and the like.
Step S140: if a starting feedback signal fed back by the spraying module 600 is received, a first actual parameter value is obtained, the first actual parameter value is compared with a first preset parameter value, a first comparison result is generated, and the first actual parameter value of the spraying module 600 is adjusted according to the first comparison result.
It should be understood that the first actual parameter value may be an actual pressure value, and the first preset parameter value may be a preset pressure value; for ease of understanding, one example is as follows: the spraying module 600 includes a second control unit 610, a driving unit 620, a blower unit 630, a nozzle unit 640 and a pressure sensor 650, after the second control unit 610 works, a start feedback signal is fed back to the local control module 200, an actual pressure value measured by the pressure sensor 650 is fed back to the local control module 200, the local control module 200 compares the actual pressure value with a preset pressure value, if the actual pressure value is not less than the preset pressure value, a stop speed-raising signal is generated to the second control unit 610, and if the actual pressure value is less than the preset pressure value, the speed-raising of the driving unit 620 is controlled until the actual pressure value measured by the pressure sensor 650 is greater than the preset pressure value.
Step S150: and if the starting feedback signal fed back by the spraying module 600 is not received, the first starting signal is sent to the spraying module 600 again.
It should be understood that if the start feedback signal fed back by the spraying module 600 is not received, the step S120 is returned to send the first start signal to the spraying module 600 again.
Step S160: judging whether the spraying module 600 fails within a first preset time period, and if the spraying module 600 fails, sending a first failure signal to the remote control module 100 and simultaneously sending a locking signal to the transmission module 400 and the atomizing module 500; if the spraying module 600 has no fault, the transmission module 400 and the atomization module 500 are started according to a preset rule.
It should be understood that the blocking signal may be a signal that keeps the module in its original state and avoids malfunction, a signal that prevents receiving an operation or control instruction, or a signal that prevents executing an operation or control instruction; the first preset time period may be set by software or by triggering a timer, and in this embodiment, after the spraying module 600 starts to work, that is, after the spraying module 600 feeds back a start feedback signal, a preset countdown timer is triggered at the same time, where the initial time set by the countdown timer is a certain multiple of the time for the outlet pressure of the nozzle unit 640 to reach the normal pressure value under the condition that the spraying module 600 is normally started, and the normal pressure value is the first preset parameter value.
In the remote control testing method for the fire detector of the nuclear power station in the embodiment, the first starting signal sent by the remote control module 100 is acquired and self-maintained to send the first starting signal to the spraying module 600, and then according to the judgment of whether the spraying module 600 is in fault or not in the first preset time period, a first fault signal is sent to the remote control module 100 and a blocking signal is sent to the transmission module 400 and the atomization module 500 at the same time or the transmission module 400 and the atomization module 500 are started according to preset rules, under the control of the remote control module 100, the control of the transmission module 400, the atomization module 500 and the spray module 600 ensures that the transmission module 400, the atomization module 500 and the spray module 600 can work normally to complete the test of the fire detector of the nuclear power station, avoids the misjudgment of the fire detector of the nuclear power station when the spray module 600 fails, the feasibility and the accuracy of remote testing of the nuclear power station fire detector under remote control are improved.
In one embodiment, the determination of whether the spray module 600 is malfunctioning is specifically:
when the start feedback signal is not received within the first preset time, it is determined that the spray module 600 is malfunctioning.
It should be appreciated that the failure to receive the activation feedback signal within the first predetermined time indicates that the spray module 600 is not properly activated or is not properly signaled.
When the start feedback signal is detected, whether the first actual parameter value reaches the first preset parameter value within the second preset time period is judged, and if the first actual parameter value does not reach the first preset parameter value within the second preset time period, the spraying module 600 is judged to be in fault.
It is to be understood that the duration of the second preset time period may be equal to the duration of the first preset time period.
Referring to fig. 7, in one embodiment, the activating the atomization module 500 according to the predetermined rule includes:
step S210: a preparatory activation signal is sent to the nebulizing module 500.
Step S220: and detecting whether the atomization module 500 receives a locking signal within a third preset time period.
Step S230: if the atomization module 500 does not receive the blocking signal, a second actual parameter value fed back by the atomization module 500 is obtained, and the second actual parameter value is compared with a second preset parameter value.
It should be appreciated that the second actual parameter value may be an actual temperature value, and in one embodiment, the second actual parameter value may be a temperature value measured by the fogging module 500.
Step S240: when the second actual parameter value is smaller than the second preset parameter value, sending a first starting signal to the atomization module 500;
step S250: and when the second actual parameter value is not less than the second preset parameter value, sending a stop signal to the atomization module 500.
Whether the atomization module 500 receives the locking signal is detected firstly in the implementation, the phenomenon that the atomization module 500 is started by mistake when the atomization module 600 is in a fault state is avoided, and then the atomization module 500 is started or stopped by comparing a second actual parameter value with a second preset parameter value of the atomization module 500, so that the controllability of the atomization module 500 is ensured. It should be understood that: when the spray module 600 is in a failure state, that is, when the spray module 600 cannot be normally started, the atomization module 500 continuously conveys the atomized reagent to the failed spray module 600, which may cause the atomized reagent to be abnormally discharged, thereby causing reagent waste and damage to the equipment due to excessive pressure values caused by excessive accumulation of the atomized reagent in the spray module 600 and the atomization module 500.
Referring to fig. 8, in an embodiment, the starting the transmission module 400 according to the preset rule includes:
step S310: a preparatory initiation signal is sent to the transmission module 400.
Step S320: and detecting whether the transmission module 400 receives the blocking signal within a fourth preset time period.
It should be understood that the duration of the fourth preset time period should be greater than the duration of the first preset time period.
Step S330: if the transmission module 400 does not receive the blocking signal, acquiring a third actual parameter value;
the third actual parameter value may be an actual temperature value fed back by the atomization module 500, and the third actual parameter value and the second actual parameter value may be the same temperature value.
Step S340: comparing the third actual parameter value with the third preset parameter value and generating a third comparison result;
it should be understood that the third comparison result includes: the third actual parameter value is smaller than the third preset parameter value, the third actual parameter value is equal to the third preset parameter value, and the third actual parameter value is larger than the third preset parameter value.
Step S350: if the third comparison result is the target comparison result, a first start signal is sent to the transmission module 400.
In this embodiment, the target comparison result is that the third actual parameter value is greater than the third preset parameter value, that is, if the actual temperature value of the atomization module 500 is greater than the preset temperature value, the transmission module 400 is controlled to deliver the reagent to the atomization module 500.
In this embodiment, whether the transmission module 400 receives the blocking signal is detected first, so that the transmission module 400 is prevented from being started by mistake when the spraying module 600 is in a fault state, and then the transmission quantity of the transmission module 400 is ensured to be the target demand by obtaining the third actual parameter value fed back by the spraying module 500 and comparing the third actual parameter value with the third preset parameter value. It should be understood that when the spray module 600 is in a failure state, that is, when the spray module 600 cannot be normally started, the continuous delivery of the reagent from the delivery module 400 to the atomization module 500 may cause the reagent to be accumulated in the atomization module 500 and/or the spray module 600, which may further cause damage to the atomization module 500 and/or the spray module 600, waste of the reagent, and misjudgment of the test result due to deviation of the output value caused by excessive reagent in the atomization module 500 and/or the spray module 600 after normal start.
Referring to fig. 9, in one embodiment, before sending the first start signal to the spray module 600, the method further includes:
step S410: the acquired volume feedback signal fed back by the container module 300 is detected.
The container module 300 includes a plurality of annunciators, each of which is located at a different location on the container module 300, and each of which feeds back a corresponding volume feedback signal to the in situ control module 200 when the reagent in the container module 300 is below the annunciator.
Step S420: when the acquired volume feedback signal is the first volume feedback signal, the first volume alarm information is sent to the remote control module 100 and the first start signal is normally sent to the spray module 600.
Step S430: and when the acquired capacity feedback signal is a second capacity feedback signal, locking the first starting signal sent by the remote control module 100 and sending second capacity alarm information to the remote control module 100.
It should be understood that the first activation signal sent by the locking remote control module 100 can be understood as: the first starting signal sent by the remote control module 100 is normally received, but the first starting signal is not sent to the spraying module 600, the transmission module 400 and the atomization module 500; the second volume alarm has an alarm level higher than the first volume alarm.
In this implementation, the acquired volume feedback signal fed back by the container module 300 is detected, and the corresponding volume alarm information remote control module 100 and the corresponding control signal to the spraying module 600, the transmission module 400 and the atomizing module 500 are generated according to the volume feedback signal, so that the reagent balance is known in real time and is locked by the serious shortage of the reagent balance, the manpower waste caused by the fact that a user needs to check the reagent balance by himself or herself at any time is avoided, and the misjudgment of the nuclear power station fire detector caused by the shortage of the reagent due to the fact that the user forgets to add the reagent is avoided.
The corresponding stopping method of the remote control testing device of the fire detector of the nuclear power station is as follows:
step S510: the stop signal sent by the remote control module 100 is obtained and self-maintained.
Step S520: the self-holding of the spray module 600 is eliminated.
Step S530: a stop signal is sent to the nebulizing module 500.
In one embodiment, the atomization module 500 de-energizes the heating wire loop to stop the heating and atomization of the reagent after receiving the stop signal.
Step S540: a stop signal is sent to the transmission module 400.
In one embodiment, the in-situ control module 200 locks the loop transmitted from the transmission unit 420 to the atomization module 500, sends a reverse signal to the motor controller in the first control unit 410, and simultaneously starts a countdown timer, after the countdown timer finishes counting, triggers to cut off the reverse starting loop, opens the loop lock transmitted from the transmission unit 420 to the atomization module 500, and realizes the backflow of the liquid reagent, the stop of the transmission unit 420 and the lock reset of the starting loop;
step S550: a stop signal is sent to the spray module 600.
In one embodiment, the spraying module 600 starts a delay loop after receiving the stop signal, blows out the residual mist and cools the heating element within a preset time period, and stops the operation of the blower unit 630 after the delay is finished.
