Description

M281843 VIII. New type description: [Technical field to which the new type belongs] This creation does not relate to the structural improvement of an instrument, especially a multi-functional instrument structure applicable to various types of machines. [Previous technology] Various monitoring instruments are used in daily life (such as temperature leaves for measuring body temperature, speedometers, tachometers, etc. used in automobiles). But in some cases,

If the meter is not accurate enough or the monitoring range is too small or inconvenient to use, it must be installed separately to read the required information. However, in the above cases, this situation will inevitably occur, that is, the presented data is inaccurate with the real data or the situation is not judged; this situation occurs because of the drive circuit of the monitoring instrument or The control program cannot be read due to incompatibility with the monitored equipment or because the signal source of the instrument has been signal-encrypted, resulting in a misjudgment or incomprehension of the monitoring instrument. Here, only the car instrument is taken as an example. Come as an explanation. For example, the speed range of an hourly speedometer of a car whose original waste is damaged is 0 ~ ιδ〇km / h '. The range of the tachometer is 0 ~ 8_RPM. Users need to increase the speed range by G ~ The 220 tachymeters and tachometers with a speed range of hidden pM, however, have errors in the performance of the tachometer on the car, which has a performance value. Therefore, when the instrument's program or drive circuit is designed according to the general rule, it can only be applied to some models. If it is used for models with different signal rules, there will be errors or unreadable conditions. 5 M281843 In addition to the current electronic instrument movements, there are two types of air coils (air⑽) and motors (ST ™ M_R). The method can be programmed or controlled by a transistor or a drive circuit. However, due to the variety of the instrument, each different instrument requires different parts and drive circuits to match, which results in a large surface area of the component or the finished product of the producer or seller, and also extends the production time. In addition, in the current use of the meter, there is a method for transmitting various sensor signals to the control box, which is transmitted to the meter in a data-encoded package after being encapsulated. The meter itself has a built-in data processing IC and a signal transmission port. The data can be transmitted to the instrument through a serial connection method, and then the packet data can be unraveled by the individual instrument, and the instrument's actions are performed individually according to the exclusive code; however, such use and operation method has a considerable disadvantage for practical use. That is, the instrument cannot be operated without a control box; in other words, in order to operate the instrument, a control box must be additionally constructed to achieve the purpose, and the use of this product causes an additional burden on consumers. Moreover, in the current instrument lighting method, it can be divided into back light guide, side light guide, etc. 'There are many types of light sources used, including pseudo-filament bulbs, cold cathode tubes (muscles), cold light sheets (EL), organic Light-emitting diodes (_ etc., no matter what light-guiding method and material is used, the ultimate goal is to achieve a bright and uniform light-guiding effect, but because the aforementioned light sources can only be connected with the instrument panel when illuminated Brighter light-emitting points at the corresponding places do not make the entire instrument panel bright. In addition, in the current instrument structure, there will be a ring-shaped ring as a pressing force. 6 M281843 It is limited to pressing and not only There are parts of the instrument panel, but the variability of their functions in the past. In addition, traditional monitoring instruments are produced according to a specific purpose, and cannot be used for multi-purpose purposes. Therefore, in the production of instruments In terms of methods, a single specification is adopted for mass production according to the different functions or types of meters, that is, special & / moson-seeking meters are produced according to specific uses. Such a production method may be There is a large amount of quantitative production, but there are many types of instruments. This will cause a large amount of material inventory costs for the producer, which will increase the production cost and cause operational difficulties. Therefore, the commonly used instruments cannot meet the needs of practical use. [New content]-Therefore, the main purpose of this creation is that, through the design of the central processor, Xian Dingzao Wucai and δ Ji Yi Zaofan, the drive control unit, monitoring unit and wireless transmission unit, and Make the instrument to be applicable to a variety of machines and equipment. ▲ Another purpose of this creation is to automatically learn and correct the programs that can detect the signals generated by the operation of various machines.

Another purpose of this creation is to be able to adjust a selection switch after inputting a variety of exclusive signals into a meter with multi-function monitoring capabilities. And then show its corresponding warning action. 'Another purpose of this creation is to use a wireless controller to identify different The type of meter, and the effect of individual operation. M281843 The other part of this creation is that it can improve the meter's illumination and the light source is original—a aa γ degree order is to increase the guidance of the meter ring In order to achieve the above-mentioned purpose, the light is a structural improvement of the instrument, which includes an outer casing with a-watch ring and a transparent cover at one end edge.

Please refer to the "third picture", which is a schematic diagram of the first embodiment of this creation. Back ... After Ding Tianben created and connected to the external machine A, if he wants to use the correction memory sheet 7 to set different machines, he uses "subtract or" divide "or" add "or" subtract "in the signal-generating program. Method, grab the read signal of any "", (or a special point), and use the signal as a reference point, then" multiply "or" divide "the remaining signals by an equal proportion. "" Or "phase or subtraction" and then show it differently, that is, when the source of the signal changes, the proportion of the temple that is output changes. In this way, {the shape of the tube signal source, such as the number of pulses, voltage, resistance, etc.) can be displayed in a correct form after comparison and correction. An example is as follows: When a car has a speed of 100 KM / Η ', the number of pulses is Li, so 10 KM / 时 per hour is ιΗZ. This is an equal proportion rule. When performing signal comparison and correction, any point or a specific point is Base point, press its control button 5 1 Make the program memorize the relative relationship between the signal source and the performance value via the central processing unit 3, if the 'correct performance value is corrected, it means that the setting is complete; if there is an error, perform detailed : Fine-tuning 'until the correct value appears on the monitoring instrument, so that all the signal values of the monitored machine can be displayed more completely and precisely. An example of the operation correction method is as follows: The user installs a speedometer on the car, but sees that there is an error between the speedometer of the original car and M281843, so a correction action is required.

When the user is driving on the road or in the maintenance field, the vehicle is elevated and the four wheels are idling to generate an hourly speed signal. Based on the speedometer of the original vehicle, when accelerating to 1 至 / H, the control button 51 is pressed to start the correction memory. Unit 5, after the program is compared by the central processor 3, 'If the monitoring instrument using the program correction memory unit shows the same value as the speedometer of the original car', it means that the setting is complete. If a different value appears (such as Satoshi M / Η or 80KM) / H), then adjust again, increase or decrease, until the monitoring instrument appears face M / H, it means that the calibration is complete. Since then, the monitoring instrument has always learned the signal output mode of the monitored machine and converted it to the correct value for use by the user. Through automatic comparison and calibration of the program, the monitoring instrument can be applied to various machines or instruments and equipment. The calibration memory unit 5 can obtain more accurate or larger monitoring values due to program control and learning to meet the needs of different users, and can greatly reduce the high cost of tailor-made to adapt to different monitored instruments or machines.
