Description

[Detailed Description of the Invention] This issue #3 is a diagnostic fl that examines the condition of the vehicle, including the engine 11fa, rectification rivet placement, etc.! Regarding i-device.

The optical system targeted by this invention is shown in FIG. The three-phase alternating current is driven by engine C2 (not shown)! Coil 1 & 11 machines.
~1c and a coil 1d for applying a magnetic field. Coil 1a
~1c Connected to the rectifier I2 that performs full-wave rectification of three-phase alternating current *Give n
, the coil 1d, the terminal 2a of the rectifier 2 and the 1-pressure adjustment holder 3
Connect between the terminal 3a and the terminal 3a. The rectifier 2 is connected to the terminal 2a of the rectifier 2, the large terminal 3b of the rectifier 2, the ground field n* terminal 3C, and the terminal 1 of the χ storage battery 5 connected to the terminal 2 of the χ storage battery 5 through the key switch 4, and the coil 1d is initialized. A terminal 3d is connected to input the pressure of the second skewer to be excited. Terminal 3b and terminal 3d
There is a connection 6f'+1 between the two and a large indicator light 6 indicating that the light storage battery 5 is flowing. Rectification &17
Terminal 2btj of M2 is the positive output terminal, connected to the positive terminal of the storage battery 5. = m ground a;nru.

Explain the operation. A large key to start the engine.
□When the switch 4 is turned on, the storage battery 5η) and the key switch 4, - the terminals 3d, 3b of the pressure adjustment 1i13,
Initial movement M1 via coil 1d, terminal 3& and terminal 3c
When the IIA current flows from the field magnetomotive force or the coil 1d, the indicator light 6 lights up due to the voltage difference between the terminals 3b and 3d. When the engine (not shown) is started by turning on the key switch 4, the child armature of the generator 1i111 rotates, and the coils 1a to 16t: the main wt storage pressure is induced δn,! After the first flow is rectified from the 2C and 2C, the CII pressure adjustment pin 3 is applied through the terminals 2a and 3b.

Voltage regulator 3, the voltage at terminal 3b is set to a predetermined level (1 m
The excitation current of the coil 1d is controlled by connecting an internal contact (not shown) so that C2 becomes . When the voltage difference between the terminals 3b and 3d disappears, the indicator light 6 goes out, indicating that the valve ring is in a serious condition. By simply lighting up the 852 display at the rising edge of the 62 *S* signal, you can detect other abnormalities such as the excitation circuit'
Of course, even if there is a flow line, 1 Arr of the output terminal (2b) of rectifier II*, etc., it is necessary to diagnose the presence of an abnormality.
1 and 7e with serious drawbacks.

This BA is a large-sized 42-unit RTFC that solves the problem of the above-mentioned technology, inputs the status information of each part of the cold water system, performs a late tS diagnosis, and (results of The purpose is to provide a diagnostic equipment that can display on the display!

Hereinafter, an embodiment of the present invention will be explained in Fig. 2 (two explanations will be given). A child pressure conversion circuit that converts the voltage of 2a to a heavy pressure of an appropriate level, an analog-to-digital converter that converts the output of this 1-voltage f conversion circuit to digital, and the output of the analog-to-digital converter as data and Cet as data. The diagnostic section includes a computer that performs the diagnostic processing of the vehicle.The display panel consists of a plurality of light emitting diodes 1, 1, and 1, placed at a suitable position on the vehicle circle, for example, on the divider panel. To selectively light up (= more characters, numbers. 111
．． 1, etc., and display the results input from a%'-IFl@7 as:,'.

Next, two operations will be explained. The diagnostic section 7 periodically reads the neutral point 0 of the 14111 1118 child, the storage battery 5, and the pressure at the terminal 2a of the rectifier 2 as status information for Mitsushi. It is well known that when the key switch 4 is off, 32 indicates the true value, and if 1 is on, the engine is started, and the engine 1 is on the valve. The state (= indicates a unique change in the process. Therefore, for example, if the voltage at the neutral point of the power generation unit 111 is zero, the engine is on, and the voltage at the storage battery 5 and terminal 2a is normal, the generation will occur. '481
1 has no valve, and it is diagnosed that there is an abnormality in the belt that rotates 7n.

1fc, storage battery 50 dust pressure does not change by more than the predetermined i1 at engine i2 and on, and if the voltage at neutral point 0 is normal, terminal 2b (: external rrh is diagnosed).

In addition, there are also changes in the relationship between the two people's strength and pressure, and the mutual power relationship between the two individuals.・71 et al.'s diagnostic results for JIA are sent to the display panel 8 and displayed.

In addition, in the above example, the status information of location 3a of the light terminal system was read, but in addition, many locations #j: Inserting the delusion stick ≦: τ is also good, and the status information is In addition to the spring voltage, it may also be the '4 current of the negative part, the degree of contraction, the rotational speed of the WaS element, etc.

The above ↓ (2. If Q11≦2zn, the state of multiple parts of the light 11 system is read periodically and the name is diagnosed, so the state of the secondary system can be accurately known. ,
This has the effect of making it easier to predict the occurrence of failures and to discover them.
