The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses the total wind undervoltage warning of a kind of locomotive device, when on the low side warning of the total wind pressure value of the total reservoir of locomotive.
Concrete, as shown in Figure 1, the total wind undervoltage warning of the disclosed locomotive of present embodiment device comprises: pressure transformer 101, controller 102 and annunciator 103, wherein:
In the total wind undervoltage warning of the disclosed locomotive of the present embodiment device, pressure transformer 101 detects total wind pressure value of the total reservoir of locomotive in real time, and transmit it to controller 102, this controller internal memory contains threshold value, when receiving the total wind pressure value of the total reservoir of locomotive that pressure transformer sends, whether total wind pressure value of judging the total reservoir of described locomotive is lower than described threshold value, when total wind pressure value of judging the total reservoir of locomotive is lower than threshold value, generate control command, control annunciator 103 is reported to the police, and reminds the driver to note.
Concrete, on the node on locomotive main reservoir pipe road threeway being set, first and second port of this threeway links to each other with this locomotive main reservoir pipe road, and the 3rd port links to each other with pressure transformer by valve.Pressure transformer detects total wind pressure value of the total reservoir of locomotive in real time, and this pressure signal is converted to electric signal transfers in the controller.
The total wind undervoltage warning of the disclosed locomotive of present embodiment device need adopt direct supply, and its operating voltage can be 72V～144V, and working current is 0.2A.
And, the controller in the total wind undervoltage warning of the disclosed locomotive of the foregoing description device, structure comprises as shown in Figure 2: memory cell 201, receiving element 202, comparing unit 203 and instruction generation unit 204, wherein:
Receiving element 202 links to each other with the pressure transformer of the total wind undervoltage warning of locomotive device, is used to receive the total wind pressure value of the total reservoir of locomotive that described pressure transformer detects and sends;
Comparing unit 203 links to each other, is used to compare the total wind pressure value of the total reservoir of described locomotive with receiving element 202 respectively and whether is lower than described threshold value with memory cell 201;
Concrete, can store a comparison threshold value in the memory cell 201, be specially 700KPa, at this moment, when receiving element 202 receives the total wind pressure value of the total reservoir of locomotive that pressure transformer sends, transmit it to comparing unit 202, comparing unit 202 obtains the comparison threshold value of memory cell 201 stored, judges whether the total wind pressure value of the total reservoir of locomotive is lower than this threshold value, when judgement is lower than threshold value, instruction generation unit 204 generates control command, the control alarm equipment alarm.
Continuous reduction along with the total wind pressure value of the total reservoir of locomotive, injury to equipment such as Pneumatic brake systems on the locomotive may increase, and embody emphatically for needs this moment, therefore, contain two comparison threshold values at memory cell 201 internal memories, the first comparison threshold value is 700KPa; The second comparison threshold value is 500Kpa.Concrete, receiving element 202 receives the total wind pressure value of the total reservoir of locomotive that pressure transformer sends, transmit it to comparing unit 202, comparing unit 202 obtains two comparison threshold values that are stored in the memory cell 201, respectively the total wind pressure value of the total reservoir of described locomotive and first threshold, second threshold value are compared, when judging that the total wind pressure value of the total reservoir of described locomotive is lower than first threshold, instruction generation unit 204 generates elementary alarm command, and the control annunciator carries out elementary warning; When comparing unit judged that the total wind pressure value of the total reservoir of described locomotive is lower than second threshold value, instruction generation unit 204 generated degree of depth alarm command, and the control annunciator carries out the degree of depth and reports to the police.
The mode that the disclosed annunciator of the utility model embodiment is reported to the police can be for the flicker of: indicator lamp, blow a whistle or blow a whistle the indicator lamp flicker time.
And, in the above-described embodiments, elementary the blowing a whistle when mode that annunciator carries out elementary warning can be glimmered for indicator lamp, the frequency that blow a whistle this moment can be 2 times/S; Annunciator carry out mode that the degree of depth reports to the police when being the indicator lamp flicker degree of depth blow a whistle, the frequency that blow a whistle this moment can be 3 times/S.
The total wind undervoltage warning of the disclosed locomotive of the foregoing description device also has self-checking function, and promptly the mode of reporting to the police by the realization of input detection signal control annunciator judges whether the total wind undervoltage warning of this locomotive device can normal operation.
Concrete, described controller also comprises the detection signal receiving element that the and instruction generation unit links to each other, and is used to receive the detection signal of extraneous input, and transfers to the instruction generation unit, after the instruction generation unit receives detection signal, generate control command control alarm equipment alarm.
Because just detect device this moment, so what the instruction generation unit generated is elementary alarm command.
And the specific implementation of described detection signal receiving element is, test button is set on controller, and after this test button was pressed and continued 3S, the and instruction generation unit linked to each other; When test button was not pressed, the and instruction generation unit opened circuit.The specific implementation process is:
The total wind undervoltage warning of locomotive device devote oneself to work and alarm-free situation under, press the test button on the controller, continue 3S after, the instruction generation unit is confirmed detection signal, generates elementary alarm command, the control annunciator carries out elementary warning; Unclamp test button, warning automatically terminates.
Each embodiment adopts the mode of going forward one by one to describe in this specification sheets, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
