Pay attention to the suitability of choosing ppe

The maintenance of instrumentation is an indispensable part in the electronics market. Instrumentation and meter companies can only make qualified products into the market by virtue of their good detection technology. The technical staff of instrumentation must have good electronic expertise. The foundation also requires extensive field experience.

1, knocking hand pressure method often encounters the phenomenon of good or bad operation of the instrument, this phenomenon is mostly caused by poor contact or welding. For this situation, tapping and hand pressure can be used.

The so-called "knocking" is to gently hit the board or component with a small rubber head or other knocker to see if it can cause an error or stop failure. The so-called "hand pressure" is when the fault occurs, after the power is turned off, the plugged parts and the plug and the base are again pressed firmly by hand, and if the power supply is turned on, it will eliminate the fault. If it is found that when the cabinet is normal and the beat is not normal, it is better to re-insert all the joints and try again. If you are unsuccessful, you have to find another solution.

2. The observation method uses vision, smell, and touch. In some cases, the damaged components will discolor, blistering, or burn spots; burned devices will produce some special odors; short-circuited chips will become hot; visible or unwelded areas can also be observed with the naked eye. .

3. Exclusion method The so-called exclusion method is a method of determining the cause of failure by inserting and removing some plug-in boards and devices. When the instrument returns to normal after removing a certain board or device, it indicates that the failure occurred.

4. The replacement method requires two instruments of the same type or sufficient spare parts. Replace a good spare with the same component on the faulty machine and see if the fault is eliminated.

5. The comparison method requires two instruments of the same type, and one is in normal operation. Use this method also has the necessary equipment, for example, multimeter, oscilloscope and so on. According to the nature of comparison, there are voltage comparison, waveform comparison, static impedance comparison, output comparison, and current comparison.

The specific method is: let the faulty meter and the normal meter operate under the same conditions, and then detect the signals of some points and then compare the measured two signals. If there are differences, it can be concluded that the fault is out here. This method requires maintenance personnel with considerable knowledge and skills.

6, temperature rise and fall Sometimes, the instrument work for a long time, or in the summer when the working environment temperature is higher, there will be failure, shutdown check is normal, stop for a period of time and then boot again and normal, after a while there is a failure. This phenomenon is due to the poor performance of individual ICs or components, and the high temperature characteristic parameters do not meet the requirements of the specifications. In order to find out the cause of the malfunction, the so-called cooling down method can be adopted, that is, when the fault occurs, the anhydrous alcohol is wiped with a cotton fiber at a place where the fault may occur, and the temperature is lowered to observe whether the fault is eliminated. The so-called warming is artificially raising the temperature of the environment, such as using a soldering iron near the point of doubt (note that the temperature must not rise too high to damage the normal device) to see if the fault appears.

7, riding shoulder law riding shoulder method is also called parallel law. Place a good IC chip on the chip to be inspected, or connect good components (resistance capacitors, diodes, transistors, etc.) in parallel with the components to be inspected to maintain good contact if the fault is caused by an open circuit inside the device or For poor contact and other reasons, this method can be ruled out.

8. Capacitance bypass method When a circuit produces a strange phenomenon, such as a display chaos, a capacitor bypass method can be used to determine the part of the circuit that has failed. Connect the capacitor across the power supply and ground of the IC. Connect the transistor circuit across the base input or collector output. Observe the effect on the fault. If the fault phenomenon disappears when the capacitor bypass input is inactive and its output is bypassed, a fault is identified in this stage of the circuit.

9, state adjustment method In general, before the failure is not determined, do not touch the components in the circuit, especially adjustable devices, such as potentiometers. However, if multiple reference measures are taken in advance (for example, position marks or voltage values ​​or resistance values ​​are measured before being touched), they are allowed to act if necessary. Maybe after some change, the fault will be eliminated.

10, isolation method Fault isolation method does not require the same type of equipment or spare parts for comparison, and safe and reliable. According to the fault detection flow chart, segmentation and enveloping gradually narrow down the fault search range, together with signal comparison, component exchange and other methods, the fault will generally be quickly found.

With the rapid development of pillar-type industries such as residential, automobiles, medium to high-end office buildings, and hotels, and the growing demand for highly protective lock products from defense, public security, and financial systems, the outlook for the premium lock market is optimistic. According to experts, high-tech products, such as biometrics and electronic technology, are currently in a blank stage in the consumer market of locks. However, the desire of consumers in this area is increasing every year.

The lock-making enterprises have developed IC card electronic door locks, electronic code locks, encrypted magnetic card door locks, floor apartment intercom alarm systems, valve locks, and fingerprint locks. Because the high-end locks have high technical content, more prominent humanity and individualized features, the profits of the products are also relatively high. In addition, with the rapid replacement of lock products, high-end locks will gradually become the mainstream of locks.

A lock may seem simple, but it must be completed through 110 processes. The lock industry is not only a traditional industry, but also has close links with the new and high technologies. Today, with the rapid development of lockmaking technology, advanced equipment and design levels are not mastered. With a group of highly qualified professionals, it is difficult for enterprises to lead in the industry. This year's COPPER prices have fluctuated and the locks have encountered unprecedented غير مجاز مي باشدt pressures. In the first half of this year, the prices of raw materials such as copper and ALUMINUM rose several times. As the غير مجاز مي باشدt rises, the rising price of the product can not reach one-tenth of the غير مجاز مي باشدt. If the price of the product rises as much as the غير مجاز مي باشدt, the customer will lose. Therefore, business households have stated that the industry urgently needs technology and industrial upgrading to update its brand innovation model. Innovations in the lock industry require companies to change their concepts, change ideas based on imitation, master independent technologies, increase investment in equipment, technology, R&D, and patent innovation, increase product technology content, and increase product differentiation; companies should pay attention to Promote brand awareness and implement brand strategy, so as to change their position, grab high-end market share, and promote the healthy and rapid development of the industry.

The more and more styles of hardware locks, along with the warming of real estate and the acceleration of urban processes, have greatly stimulated the consumer demand of the decorative hardware market. Although a small decoration hardware is inconspicuous, but the product function style is more and more optimized and refined, the variety of species, style contests.

There are more and more styles of hardware locks, many of which look more like one or a small animal, but its function is a lock. In the market, the more popular civilian locks are mainly spherical, three-bar type circular cover handles, embedded long cover door locks, and lock body handles. The other trend that is most used in the inner door is the channel and the auxiliary lock (the most important feature of the anti-theft function). The author learned from the market that the currently available locks are mainly brass, stainless STEEL, and bronze. The treatment of surface color is mainly a combination of two color combinations. In terms of price, the door lock is generally more than 100 yuan, expensive to 800 yuan or more; inside the room lock is relatively cheap, 80 yuan can buy a good lock.

The future development direction of locks in China is:

1. The development of high-end locks The high-end locks have a bright market prospect. Because the high-end locks have high technical content, more prominent humanity and individualized characteristics, the product profits are also relatively high. Should increase investment in high-tech locks and promote the structural upgrading of China's lock industry.

2. The implementation of brand-name strategy lock industry well-known companies and brands can produce huge economic and social benefits, and now China's locks face more severe challenges, competition prompted companies to respond positively, so that China's production from locks to power from a big country.

3. The implementation of diversified development of locks companies to accurately position themselves and the market, the implementation of multiple development. In the so-called field, we design locks that cater to the public and have individual needs, avoiding the fierce competition brought about by similar public locks. In addition, companies must take the road of a diversified market and avoid being affected by a certain factor and affecting the fundamental development of the company.
