Description

Technical Field

[0001] The present invention relates to a fault detection device, and particularly to a multi-person fault detection device based on a set of equipment. Background Art

[0002] In the teaching of electrical appliance fault detection, after the teacher explains the theory, specific faults are usually set for students to practice. When detecting faults, parameters such as voltage and resistance generally need to be detected. However, the wire harnesses of physical objects are all enclosed, and it is only possible to plug and unplug wire harness plugs and components. After multiple people operate, they will be damaged quickly. To avoid this phenomenon, current fault detection generally does not perform detection on physical objects, but on dedicated fault detection equipment. These fault detection equipment generally lead out the wires of wire harness plugs, components, etc. to dedicated detection terminals, and set faults of wires or components through a computer. This also results in the high price of fault detection equipment. Taking the automotive major as an example, the price of an engine fault detection device is often 2-5 times the price of a brand-new engine. Therefore, schools usually only equip a small number of fault detection devices. When students practice, they can only take turns in groups, which results in extremely low teaching efficiency. Therefore, a fault detection device with a low price and capable of satisfying multiple people to operate simultaneously is needed. Summary of the Invention

[0020] A multi-person fault detection device based on a set of devices, including a set of detection devices. The detection devices include various circuit components. Specifically, they can include a battery, a relay, an insurance, a lamp, a switch, a control unit, and wires, etc. They are electrically connected through a circuit diagram as shown. Detection terminals can be directly set or main detection terminals can be led out at the component terminals according to the characteristics of the component terminals. For example, points a and n at the battery U are direct detection terminals, points b, c, d, and e at the relay K, points f and g at the insurance F, points h and i at the switch S, points j, k, l, and m at the bulbs L1 and L2, and points r, p, and q at the control units 1 and 2 are main detection terminals. It also includes multiple detection panels. Multiple secondary detection terminals are connected in series or parallel to the multiple main detection terminals. These secondary detection terminals include a1 - a5, b1 - b5.... etc. The secondary detection terminals are respectively fixed on the detection panel, such as Figure 1 shown in the circuit diagram.Figure 2 , 4 as shown

[0021] Its working principle is as follows: The r point of control unit 1 and the p point and q point of control unit 2 are normally at low level, such as 0V. When the switch S is closed, the switch of relay K is closed, and the bulbs L1 and L2 are lit.

[0022] For another example Figure 3 as shown, an aviation plug or a cable is provided on the detection panel, and the main detection terminal and the secondary detection terminal are electrically connected to the aviation plug or the cable.

[0023] Preferably, there are two aviation plugs or cables.

[0024] Preferably, component terminals are provided on the detection panel, and these component terminals include a11, a21, a31, a41, a51, b11, b21, b31, b41, b51... The component terminals correspond to the detection terminals one by one in position, but are not electrically connected.

[0025] Preferably, the detection panel is connected in series by a connecting wire through the aviation plug or the cable.

[0026] Such as Figure 3 as shown, a fault simulation device is provided on or between the circuit wires of the detection device, and the fault simulation device can simulate common faults in the circuit.

[0027] Such as Figure 3 as shown, the fault simulation device is a switch, a relay, a resistor, or a PLC, a single-chip microcomputer, etc.

[0028] Preferably, a fault setting station is provided on the back or side of the detection device, and the operation parts of the fault simulation device are centrally arranged in the fault setting station.

[0029] The working principle of the present invention will be introduced below.

[0030] Such as Figure 2 as shown, when there is no fault set in the circuit, the circuit parameters that can be detected on a certain circuit component of the detection device can also be detected at the secondary detection terminal of any detection panel. For example, the battery voltage is detected at points a and n of the detection device, and the battery voltage can also be detected at a1, n1 or a2, n2 or a3, n3, etc. on the detection panel. For another example, the coil resistance of the relay is detected at points c and e of the detection device, and the coil resistance of the relay can also be detected at c1, e1 or c2, e2 or c3, e3, etc. on the detection panel.

[0031] Such as Figure 4As shown, when a fault is set in the circuit, the fault can also be detected on the detection panel. For example, if the open circuits at points a and b are set through the fault simulation device, the resistance value between points a and b measured on the detection equipment is infinite, and the resistance value between points a and b measured on any detection panel is also infinite.

[0032] To improve the consistency between the detection panel and the detection equipment, component terminals are provided on the detection panel, and circuit components are also arranged at the component terminals. The component terminals and the detection terminals correspond to each other in position but are not electrically connected. In this way, the detection panel is consistent with the detection equipment in appearance, and the detection is more intuitive. Teachers can also set faults on some simple circuit components. At this time, the teacher needs to set the same faults on all the same circuit components on the detection panel. For example, when setting faults on a relay and a bulb, the relay and the bulb on the detection panel need to be set with the same faults. Students can perform the same detections on the circuit components on the detection panel as on the detection equipment.
