[0019] The testing device provided in the present application is further described in detail herein in conjunction with the accompanying drawings and specific implementation methods.
[0020] Figure 1 The structure of the multifunctional buzzer 45-H1 is shown, and its interface definition is: CM-GBU-1 DC24V+, CM-GBU-2 DC24V-, CM-GBU-3 buzzer power-on test, CM-GBU-4 alert timeout reminder, CM-GBU-5 traction permission, CM-GBU-6 DDU fault prompt, CM-GBU-7 overspeed prompt, CM-GBU-8 reversing prompt. When the corresponding interface receives a signal, a corresponding prompt is given, such as when the interface CM-GBU-6 receives a signal, it prompts DDU fault, when the interface CM-GBU-3 receives a signal, it prompts the buzzer to be powered on, and when the interface CM-GBU-4 receives a signal, it prompts alert timeout; each interface will emit a different prompt tone after receiving a signal.
[0021] In order to achieve a good prompt effect, the multifunctional buzzer is installed in the electrical box above the driver's cab table and chair, and is powered and controlled by an 8-core electrical connector. However, the various prompt sounds of the vehicle are triggered under different working conditions. Some mainline operating conditions cannot be simulated during in-depot maintenance, so the quality of some prompt sounds cannot be distinguished. In order to realize the in-depot test of the multifunctional buzzer (in-depot test refers to the test of the tram in the non-operating state in the garage), this paper discloses a tram multifunctional buzzer test device to realize the normal test of the prompt function of the multifunctional buzzer under different working conditions.
[0022] The test equipment includes: a power supply module, a switch module and a connector X1. The number of interfaces of the connector X1 matches the number of prompt signal interfaces of the tram multifunctional buzzer, and is used to realize the electrical connection between the connector X1 and the tram multifunctional buzzer. Each interface of the connector X1 is a branch, the switch module is connected in series to each branch, and the voltage required for the tram multifunctional buzzer prompt provided by the power supply module is connected to each branch through the switch module.
[0023] The power supply module is used to convert 220V AC into the voltage required for the multi-function buzzer prompt of the tram, such as 24VDC. The on / off of the switch module realizes the on / off of the connector X1 interface. The connection between the connector XI and the multi-function buzzer is realized through an electrical connection plug, or the interface of the connector XI is a plug structure, which can be directly inserted into the interface of the multi-function buzzer to realize the electrical connection between the two.
[0024] When the interface of connector X1 is powered on, the corresponding interface of the multi-function buzzer is powered on. At this time, if the prompt corresponding to the interface can be issued normally, the corresponding prompt function is normal, otherwise it is abnormal.
[0025] Figure 2 It shows that the switch module structure of the device is a self-reset button switch SB1-SB2, and the output of the power supply module is connected to the CM-GBU-3~CM-GBU-8 interface of the connector XI through SB1-SB6 (the interface is electrically connected to the interface of the multi-function buzzer). When a switch among the self-reset button switches SB1-SB6 is turned on, the voltage output by the power supply module is connected to the interface corresponding to the switch, and the interface electrically connected to the multi-function buzzer is powered on to perform a prompt function test.
[0026] Figure 3 It is shown that the switch module structure of the device is a relay. Under this structure, the test equipment also includes a switching power supply and a single-chip microcomputer. The voltage required for the multifunctional buzzer prompt of the tram provided by the power supply module is connected to the power supply end of the relay, and is connected to the single-chip microcomputer through the switching power supply module; the switching power supply module is used to provide the working voltage of the single-chip microcomputer, so that it can be powered on and run the computer program stored therein, which is an existing running light program, so that the pin connected to the single-chip microcomputer and the relay has an output cycle, the relay is connected in a cycle, and the output of the power supply module is connected to the connector XI.
[0027] The first contact of the relay is electrically connected to the interface of the connector XI, the second contact is electrically connected to the output of the power supply module, one end of the coil is electrically connected to the output of the power supply module, and the other end is electrically connected to the pin of the single-chip microcomputer. When the single-chip microcomputer pin has an output, the relay coil is energized, the first contact and the second contact are connected, and the connector XI interface is energized.
[0028] Alternatively, the first contact of the relay is electrically connected to the interface of the connector XI, the second contact is electrically connected to the output of the power supply module, one end of the coil is electrically connected to the output of the power supply module, and the other end is electrically connected to the pin of the single-chip microcomputer. When there is an output on the single-chip microcomputer pin, the relay coil is energized, and the normally closed contact of the relay is disconnected from the auxiliary contact and connected to the second contact. One end of the normally closed contact is electrically connected to the first contact, and the other end serves as the normally closed end. When the coil is not energized, it is electrically connected to the auxiliary contact; when the coil is energized, it is electrically connected to the second contact. Among them, the auxiliary contact is grounded or suspended.
[0029] Each interface of connector XI is connected in series with a relay, and the power supply is connected to the power supply module. The power supply module has an output that is connected to the switch power supply module to power on the single-chip microcomputer. The single-chip microcomputer is started so that the pin connected to the relay coil has an output cycle. When a certain pin has an output, the corresponding relay is actuated, and the output of the power supply module is connected to the interface corresponding to connector X1. The interface electrically connected to the multi-function buzzer is powered on to perform a prompt function test.
[0030] Figure 3 The device structure shown realizes automatic testing. To ensure the controllability of the structure, Figure 3 Based on the structure shown in FIG. 1 , an automatic mode button S2 is also provided. Figure 4 The voltage required for the tram multi-function buzzer prompt provided by the power supply module is connected to the switch power supply module via the automatic mode button S2.
[0031] Figure 5 It is shown that the switch module structure of the device includes self-reset button switches SB1-SB6 and relays. Under this structure, the test equipment includes a power switch S1, an automatic mode button S2, a switching power supply module and a single-chip microcomputer. The voltage required for the tram multi-function buzzer prompt provided by the power supply module is divided into two paths through the power switch S1. One path is provided to the self-reset button switches SB1-SB6. When the self-reset button switches SB1-SB6 are actuated, the interface of the connector X1 is energized. One path is connected to the automatic mode button S2. When the automatic mode button S2 is actuated, the self-reset button switches SB1-SB6 are short-circuited. The output of the power supply module is connected to the relay power supply terminal and connected to the single-chip microcomputer through the switching power supply module.
[0032] When the power switch S1 is turned on and the automatic mode button S2 is turned off, Figure 5 The structure shown is simplified to Figure 2 The structure shown in the figure has the working principle as described above and will not be described in detail here. When the power switch S1 and the automatic mode button S2 are turned on, the self-reset button switches SB1-SB6 are short-circuited. Figure 5 The structure shown is simplified to Figure 3 The working principle of the structure shown is as described above and will not be repeated here.
[0033] Figure 5 The structure shown combines manual testing and automatic testing, which are selected via the automatic mode button S2.
[0034] Because the multi-function buzzer control is powered by the whole vehicle at low voltage, the whole vehicle must be activated during the test to provide the multi-function buzzer starting voltage. To avoid the activation of the whole vehicle during the test, the connector XI of this equipment is also equipped with power supply interfaces CM-GBU-1 and CM-GBU-2 for electrical connection with the multi-function buzzer power supply interface. This interface is connected to the output of the power supply module, such as Figure 6 When the power supply is connected to the power interface of connector XI after passing through the power supply module, the multi-function buzzer is powered on and started, and the control is realized through the external power supply, which reduces the operation process and improves the production efficiency.
[0035] This device Figure 6 In the structure shown, the interface of the multi-function buzzer is connected to the connector XI, the power supply is connected to the power supply module, and the power switch S1 is turned on, the multi-function buzzer is powered on and started; if the manual mode is selected, the automatic mode button S2 is disconnected, and the self-reset button switches SB1--SB6 are manually controlled to act and perform the test; if the automatic mode is selected, the automatic mode button S2 is turned on and an automatic cycle test is performed; during the test, if each prompt mode can emit the corresponding sound, the test passes, otherwise it fails.
[0036] In this equipment, an insulated, flame-retardant, dust-proof, and corrosion-resistant self-reset push button switch is used to improve the stability and service life of the equipment.
