[0031] Specifically, the total power supply unit 100 comprises a total power supply module 110 and a test system power supply module 120, the total power supply module 110 is used for being connected with an external power supply, the external power supply is used as a total power supply for experiments, and the total power supply module 110 is used for realizing on-off control of the total power supply; the test system power supply module 120 is used as a total switch of the limited sounding controller test system and is used for controlling whether the limited sounding controller test system simultaneously supplies power to the limited sounding power supply control unit 200, the constant light test unit 300, the flashing light test unit 400 and the electric whistle test unit 500 after the external power supply is connected, so that the operation is facilitated and the power supply state of the limited sounding controller is facilitated to be controlled.
[0032] Further, the total power supply module 110 comprises a total power supply switch 111 and a first voltage converter 112, the total power supply switch 111 is connected with the input end of the first voltage converter 112, the 220V voltage input is controlled to be given to the first voltage converter 112 through the total power supply switch 111, and the first voltage converter 112 is used for converting the 220V voltage into a 110V voltage, so as to facilitate power supply to the limited sounding controller.
[0033] Preferably, the total power supply module 110 further comprises an emergency stop switch 113, the emergency stop switch 113 is connected between the total power supply switch 111 and the first voltage converter 112, and the test system power supply module 120 is connected with the total power supply switch 111 through the emergency stop switch 113, so that after the total power supply switch 111 is closed and electrified, the test system power supply module 120 can also be stopped from being powered through the emergency stop switch 113.
[0034] Meanwhile, the test system power supply module 120 comprises a first jog switch 121, a second jog switch 122, a first relay normally open end 123 and a first relay coil end 124, wherein the first jog switch 121 is in a normally open state, and the second jog switch 122 is in a normally closed state.
[0035] The emergency stop switch 113, the first jog switch 121, the second jog switch 122 and the first relay coil end 124 are connected in sequence, the first relay normally open end 123 is connected in parallel with the first jog switch 121, and the siren control unit 200, the constant brightness test unit 300, the flashing test unit 400 and the electric siren test unit 500 are all connected with the emergency stop switch 113 through the first relay normally open end 123; at this time, the first jog switch 121 serves as a power supply switch, and the second jog switch 122 serves as a power-off switch.
[0036] In operation, after closing the total power supply switch 111, the first jog switch 121 is pressed to make it closed, at this time, the first relay coil end 124 is powered, the first relay normally open end 123 is closed, and after the first jog switch 121 is released, it returns to the open state, because the first relay normally open end 123 is closed, the test system power supply module 120 remains connected, and the siren control unit 200, the constant brightness test unit 300, the flashing test unit 400 and the electric siren test unit 500 are all connected to the power supply; if the power supply needs to be disconnected, the second jog switch 122 is pressed, the second jog switch 122 is disconnected, the first relay coil end 124 loses power, the first relay normally open end 123 is disconnected, and after the second jog switch 122 is released, the second jog switch 122 is closed, and the first relay normally open end 123 remains disconnected.
[0037] Further explanation, the siren control unit 200 includes a third jog switch 210, a second relay coil end 220 and a second relay normally open end 221, the third jog switch 210 is in a normally open state, and the third jog switch 210 serves as a start switch of the siren controller.
[0038] One end of the third jog switch 210 and one end of the second relay normally open end 221 are both connected with the first relay normally open end 123, the other end of the third jog switch 210 and the other end of the second relay normally open end 221 are both connected with the second relay coil end 220, at this time, the third jog switch 210 is connected in parallel with the second relay normally open end 221.
[0039] When the first relay normally open end 123 is closed, the third jog switch 210 is pressed, the second relay coil end 220 is powered, and at the same time, the second relay normally open end 221 is closed, and the auxiliary light unit 700 is powered at this time; on the contrary, when the auxiliary light unit 700 is disconnected, the first relay normally open end 123 can be disconnected by pressing the second jog switch 122.
[0040] Further explanation, the total power supply module 110 also includes a power indicator 130, the power indicator 130 is connected with the output end of the first voltage converter 112 through the second relay normally open end 221, so that the siren controller can be prompted through the power indicator 130 after being powered, which is convenient for judging the test state.
[0041] Further, the constant light test unit 300 includes a third relay coil end 310, the flashing light test unit 400 includes a fourth relay coil end 410, and the third relay coil end 310 and the fourth relay coil end 410 are both connected to the first relay normally open end 123 through the single-pole three-throw switch 600. The third relay coil end 310 is connected to the left end of the single-pole three-throw switch 600, and the fourth relay coil end 410 is connected to the right end of the single-pole three-throw switch 600.
[0042] After the first relay normally open end 123 is closed, the operator can connect the third relay coil end 310, the fourth relay coil end 410, or neither of them to the single-pole three-throw switch 600 by turning the single-pole three-throw switch 600, and at this time, the single-pole three-throw switch 600 serves as a switch for the constant light test and the flashing light test of the auxiliary light.
[0043] When the single-pole three-throw switch 600 is connected to the third relay coil end 310, the third relay normally open end 750 of the auxiliary light unit 700 is closed, and at this time, the auxiliary light 730 is powered on and constantly lit. If the auxiliary light 730 is not constantly lit, there is a fault in the constant light function. Correspondingly, when the single-pole three-throw switch 600 is connected to the fourth relay coil end 410, the fourth relay coil end 410 is powered on, the fourth relay normally open end 760 is closed, the flashing module 740 and the auxiliary light 730 are powered on in turn, and the auxiliary light 730 flashes. If the auxiliary light 730 does not flash, there is a fault in the flashing function.
[0044] After the function test of the auxiliary light 730 is completed, the single-pole three-throw switch 600 is turned to the middle position, and the third relay normally open end 750 and the fourth relay normally open end 760 are disconnected.
[0045] Further, the siren test unit 500 includes a fourth momentary switch 510 and a fifth relay coil end 520. The fourth momentary switch 510 is in a normally open state, and the fifth relay coil end 520 is connected to the first relay normally open end 123 through the fourth momentary switch 510.
[0046] Thus, after the first relay normally open end 123 is closed, the fifth relay coil end 520 is powered on by pressing the fourth momentary switch 510, and at the same time, the fifth relay normally open end 830 is closed, and the siren 820 is powered on and emits a whistle. If the siren 820 does not work, there is a fault in the siren 820 function. When the function of the siren 820 is tested, the fourth momentary switch 510 is kept closed by pressing it, which simulates the actual working environment. The test of the siren 820 is stopped after the fourth momentary switch 510 is released, which is simple and convenient to operate and can meet different test requirements, thereby improving the work efficiency.
[0047] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
