Description

  The present invention relates to the structure of a meter, and more particularly to the structure of a multi-function meter that can be applied to various devices.

Various meters such as a thermometer, a speedometer or a tachometer are used in daily life. However, for example, when the meter is inaccurate, the measurement range is too narrow, or inconvenient in use, it is necessary to install a meter and read the data. However, under the above situation, it is unavoidable that an error occurs between the displayed data and the actual data, or a situation in which the data cannot be read out. This is a driving circuit for monitoring and controlling the meter. Or, an explanation will be given by taking an automobile meter as an example, which is caused by incompatibility between the control program and the equipment to be monitored and controlled, or the signal source of the meter becomes unreadable by the encryption technology. I do.

For example, a genuine speedometer originally installed in a car has a speed range of 0 to 180 km / h, a tachometer range of 0 to 8000 rpm, a user has a speed range of 0 to 220 km / h, and a tachometer range When a 0 to 9000 rpm meter is further installed, an error occurs between the numerical value indicated by the further installed tachometer and the numerical value indicated by the genuine tachometer originally installed in the automobile. Therefore, the detection program and drive circuit for monitoring and measuring the meter can be used only for some car models, and when used for car models with different signal rules, errors may occur or they may become unreadable. .

The current electronic meter guideline has an air core coil (AIR CORE) and a stepper motor (STEPPER MOTOR), and the drive system is controlled by program control or a transistor plus a drive circuit. In many cases, each meter requires the use of different parts and drive circuits, so that manufacturers and sellers have a huge inventory of parts and products, and at the same time, it takes longer manufacturing time.

In addition, as one of the usage methods of the meter according to the prior art, there is a method in which signals from various sensors are transmitted to a control box, assembled, and then transmitted to the meter by an encrypted packet method. The meter has a built-in data processing IC and signal transmission port, and the data is transmitted to the meter by a cascade connection method. Each meter decodes the data of the packet and operates the meter individually based on its own encoding. To execute. However, there are significant drawbacks when such a usage method is actually used. That is, if there is no control box, the meter cannot be activated. In other words, to operate the meter, it is necessary to purchase a control box, which is a heavy burden on consumers.

In addition, meter lighting systems according to the prior art can be classified into illumination from the back and illumination from the side, and the light sources used are tungsten bulbs, cold cathode fluorescent lamps (CCFL), electroluminescence (EL), organic LEDs, etc. There are many types and no matter what lighting method and material is used, the ultimate purpose is to obtain a bright and uniform lighting effect. However, when light is irradiated by the above-described light source, only a bright light emitting point is generated at a location corresponding to the meter panel, and the entire meter panel cannot be uniformly brightened. Moreover, in the meter by a prior art, although the panel is crimped | bonded by the cyclic | annular cover part, there is no more function and its changeability is scarce.

Also, all of the monitoring and measuring meters according to the prior art are manufactured only for specific applications and cannot have a plurality of applications. Accordingly, meter production produces a large number of single standard meters based on different functions and types. That is, a dedicated meter is produced based on a specific application. This production method enables mass production of a single type of meter, but there are many types of meters, which incurs the cost of material inventory for the producer and increases the production cost. Therefore, the meter according to the prior art does not meet the actual demand.

FIG. 3 is a block diagram showing a first embodiment of the present invention. As shown in the figure, after connecting the present embodiment and the external device A, when the modified storage unit 5 is operated and settings are made for different devices, the signal detection program is multiplied, divided, added or subtracted. After taking any one point (or one particular point) signal read by the method you use, and then multiplying, dividing, adding or subtracting the other signals in equal proportion with this signal as the reference point When displayed again, when the signal source changes, the signal changes proportionally and is output accordingly. In this way, any type of signal source (number of pulses, voltage, electrical resistance, etc.) can be displayed in an accurate format after comparison and correction. An example is shown below.

When the speed of one vehicle is 100 km / h, if the number of pulses is 10 Hz, the speed is 1 Hz at 10 km / h. This is an equal rule, and when performing signal comparison and correction, any one point or When a specific point is used as a reference point, the control button 51 is pressed, the CPU 3 stores the relative relationship between the signal source and the display numerical value, and if the correct numerical value is displayed after correction, the display setting is completed. If there is an error, a fine adjustment is made until an accurate value is displayed on the monitoring control meter, and in this way, all signal values of the monitoring control device are displayed in more complete detail. An example of the correction method is shown below.

When the user installs a speedometer on the car but there is an error with the original speedometer that was originally installed, correction is required.

A user travels on the road or lifts the vehicle body with a jack at a repair shop to idle the tires to generate a speed signal, accelerating to 100 km / h based on the original genuine speedometer When the correction storage unit 5 is activated by pressing the control button 51 and the programs are compared through the CPU 3, the monitoring control meter that uses the above-described correction storage unit of the program is originally installed. When the same numerical value as the speedometer is displayed, it means that the setting is completed. If a different numerical value (for example, 120 km / h or 80 km / h) is displayed, the increase or decrease is adjusted again, and the correction is completed when the monitoring meter shows 100 km / h. Since then, the monitoring meter has already learned the signal output format of the detection device, converted it into an accurate numerical value, and supplied it to the user. This modified storage unit 5 meets the different demands of each user by means of more accurate or extensive monitoring measurement values through program control and learning, and is manufactured for each monitoring control meter or device. Therefore, the high production cost can be greatly reduced.
