First, the basic principles of maintenance
1. Basic principles to be followed when performing queuing maintenance The maintenance judgment should start with the simplest things. Simple things, on the one hand, refer to observation, on the other hand, it refers to a simple environment. The simple thing is observation, which includes:
1.1 Circumstance and position of the environment around the queuing equipment (wireless communication queuing equipment, to find out whether there is interference source of wireless communication outside, focusing on observing whether there is railway, subway or airport and other similar wireless communication equipment in the surrounding environment), Power, connectors, other equipment, temperature and humidity, etc.
1.2 The phenomena exhibited by the Queue, the contents of the display, and the differences between them and the normal situation;
1.3 Internal environmental conditions, dust, connections, device colors, indicator status, etc.
1.4 The status of the software configuration of the software, system resources, operating system used, what other software is installed, hardware driver version;
Starting from the simplest things is conducive to energy concentration, which is conducive to the judgment and positioning of faults. Certain attention must be paid to making judgments and maintenance after careful observation.
2. According to the observed phenomenon, it is necessary to "first think about doing it again."
The first thing to do afterwards includes the following aspects:
2.1 think of how to do first, how to start, and then actual hands-on. It can also be said that the first analysis and judgment and then proceed with the repair;
2.2 Secondly, as far as possible, check the previous maintenance records as far as possible.
2.3 In the process of analysis and judgment, judge according to their own knowledge and experience. For those who do not know or understand well, they must consult an experienced colleague or technical support engineer for help.
3. Most queuing machine failures must be judged by the principle of “soft first and then hardâ€, that is, the whole process of maintenance judgment. It is necessary to first determine whether it is a software-induced fault phenomenon. First check the software is normal. If the failure cannot be resolved at that time, judge. For hardware failure.
4. During the maintenance process, it is necessary to distinguish between primary and secondary fault phenomena. Sometimes it may be seen that there is more than one fault phenomenon at the same time in the queuing machine, or a variety of fault phenomena occur at the same time, (eg: Can not call, voice, etc.) At this time, we should first determine the main fault repair, repair and then repair the secondary fault phenomenon, sometimes at this time the minor fault has no maintenance.
Second, the basic method of maintenance
Observation method observation method is the first important method in maintenance judgment. It runs through the entire maintenance process. Observing not only must be serious, but also comprehensive.
The observations include:
1.1 The surrounding environment;
1.2 Hardware Environment (Including Power Outlets, Terminals, etc.)
1.3 Software Environment (including other application software)
1.4 User operating habits and processes 2. The minimum system method The minimum system refers to the queuing system running the most basic hardware environment and software environment from the perspective of maintenance judgment. There are two minimum environments.
2.1 hardware minimum system is by the number of machines, communications controller, a window of the pager, voice system;
2.2 The software minimum system is the main program and voice program on the machine;
The minimum system troubleshooting method is mainly to determine that in the most basic software and hardware environment, several types of equipment are collected around the number picking machine to build the smallest and smallest system environment and see if the system can operate normally. Plays fault isolation of lines or hardware devices.
The combination of the minimum system method and the queuing division method can quickly locate the cause of the failure and improve the maintenance rate.
3, investigation add / remove method 3.1 investigation add method, is based on the minimum system, each time only add a device to the queuing system to check whether the phenomenon of failure disappears or continue to determine the location of the fault;
3.2 The operation of the removal method is just the opposite of the additive method. They are mainly matched with the replacement method to determine the fault location more accurately;
4. The isolation method is a method of shielding the device that may obstruct the failure judgment, and is a method for separating the suspected software hard to determine whether the failure has changed.
5. Replacement method Replacement method is a kind of maintenance method that replaces a good device with a suspected device to judge whether the fault phenomenon disappears. Be sure to use the same type of hardware device for testing.
6. The tapping method is generally used when a suspicion of a fault in a pager or a window screen is used to cause the device to be vibrated or distorted so as to reproduce the fault, thereby determining a maintenance method of the fault cause.
7. Fixed Suggestions Some of the faults are mainly caused by loose data cable connectors or power connectors. After troubleshooting, you should thoroughly solve the faults and fix some connectors to prevent the occurrence of similar faults.
8. Cleaning It is recommended to clean the touch screen machine regularly, such as the paper inlet of the thermal printer, CPU fan, socket, and slot, etc. Wipe with alcohol. If there is any oxidation phenomenon, use a metal plate to gently scrape.
Ash should the device with a dry brush ash, hair dryer can also be carried out ash, non-cleaned with a metal tool to operate <br> <br> three if necessary, must be powered down completely, queuing Repair steps
1. Understand the situation Before and during the service, communicate with the user and understand the current situation after the failure, and make a preliminary judgment. If we can understand the detailed fault phenomenon as much as possible, the on-site maintenance efficiency and judgment accuracy will also be improved. Understand whether the user's needs conflict with the queuing system.
2. Judgment maintenance means judgement and positioning of the observed fault phenomenon, find out the cause of the fault, and carry out the repair process.
3, inspection must be carried out after maintenance, to confirm the failure phenomenon does not appear. Also check whether other queuing machine functions properly.
Fourth, the queuing machine repair operation steps
1. In the process of repairing the queuing machine, the failure shall not be expanded as much as possible;
2. Before the maintenance, you should make a backup of the software and understand the related configuration to prepare for the recovery operation;
3, must fully meet with customers to understand the entire process of customer operations, the failure to enter what kind of operation;

2. The solution shall be divided into two categories: 2.1. The display device of the pager has no display. 2.1.1 The communication controller is powered on, and the caller can also perform the minimum environmental test at the machine.
2.1.2 Is the data line sequence from the communication controller to the counter pager consistent?
2.1.3 The crystal head of the pager data trunk is really good.
2.1.4 Has the caller data trunk broken?
2.1.5 Are all the nodes in the counter connected to the pager broken, and are there any bad three links?
2.1.6 Check whether the pager in the counter is connected by a module, check if the module is connected incorrectly, reversed or short circuited.
2.1.7 Is the data line and crystal head in the counter ready?
2.1.8 Check if the voltage of the data line is normal, 24V;
2.2 pager display can display information 2.2.1 check whether the main program is started successfully, the counter in the counter is configured correctly;
2.2.2 Is the serial port line and communication controller of the access controller connected? Is there any problem with the line?
2.2.3 Whether the serial ports needed to queue are conflicting, and whether the serial port itself is working properly.
2.2.3 What kind of test login is used by the queuing machine can be viewed in the cnfig.ini file to simplify login;
2.2.4 The minimum environment test can be used to determine whether the counter line, node, or other equipment has a fault;
2.2.5 Check whether the pager address is set correctly and conflict with other windows on the counter.
2.2.6 Check whether the pager address code is loose;
2.2.7 Is there anything in the pager RJ45 interface, or the interface is damaged;
2.2.8 Is the communication controller chip program version correct and the communication controller working properly?
2.2.9 Check with the company's engineering department whether the pager chip version is correct;
2.2.10 If there is an evaluation device, all evaluation devices and communication controllers should be disconnected from the test;
Fourth, LED
Window screen type fault 1, window screen fault phenomenon 1.1 display without any information display;
1.2 display screen, without any normal display;
1.3 Display does not display call information;
1.4 The display shows that the call number information appears, "Please call NNN number" and other information prompts;
1.5 The display is always blinking abnormally;
1.6 If half of the eight-character display shows no information;
2, the solution should be divided into two categories 2.1 display no display class 2.1.1 to see whether the 220V power supply, such as tripping to see if there is a short circuit;
2.1.2 Check whether the power cable in the display is disconnected or invisible.
2.2.3 Check whether the data line of the display card and the screen in the display screen is connected properly and whether the line is damaged;
2.2.4 Check whether there is a problem with the "inverter" in the power supply on the screen.
2.2 The display screen can display information 2.2.1 Whether the main program is open, whether the current pager can log in the call;
2.2.2 Is there any damage to the data trunk of the display to the communication controller? Are the two break sequences consistent?
2.2.3 Whether the crystal head of the display data trunk is compacted and whether the interface with the equipment is not true;
2.2.4 Use the pager to test at the end of the window screen to check whether the data is normal. 2.2.5 Check whether the address code switch of the window display is loose and whether the address code is wrongly dialed;
2.2.6 Does the display screen reflect when transmitting screens, and can send data once again to the screen?
2.2.7 The data flat cable in the display screen is connected properly, and the display card RJ45 seat is connected with the crystal head;
2.2.8 can replace the display card or the 487 chip on the display card for testing;
Fifth, sound failure
1, sound failure phenomenon 1.1 call without voice prompts but the main program shows that the connection is successful;
1.2 The voice device cannot be found on the main program;
1.3 The speed of speech is very slow when calling;
1.4 The sound quality of the call is very poor;
The 1.5 amplifiers do not produce sounds. There are no problems with other headsets testing the machine and software settings.
2, to solve this problem should be divided into two categories for troubleshooting 2.1 hardware failure 2.1.1 to see if the system is working properly;
2.1.2 Check whether the sound card is driven and whether there is an address conflict with other devices.
2.1.3 Check whether the audio cable is correctly connected 2.1.4 Check whether the power amplifier is powered on, and whether the connection of the audio cable is firm;
2.1.5 Check whether the indication switch on the power amplifier panel is consistent with the setting of the connected audio cable.
2.1.6 Check whether the audio head between the amplifier and the speaker is connected properly, whether the line appearance is damaged, or the wire of the audio line, etc.;
2.1.7 If the sound quality is not good, check whether the audio cable is damaged. Is the connector exposed with copper wire and if there is strong interference in the surrounding area?
2.2. Software failures 2.2.1 Check whether the system is infected with the virus now, use the latest antivirus software to kill it;
2.2.2 Whether the voice device settings in the main program are correct and whether it is selected as a virtual device;
2.2.3 The IP address specified by the voice device is the actual IP address of the local computer (Note: When the network cable is not connected, the system will default to the current IP address of 127.0.0.1).
2.2.4 In the advanced settings, whether there is a voice service in the counter setting;
2.2.5 The version of speech software matches the main program;
2.2.6 Is there a missing audio file path in the voice system? Is there no audio file in the folder?
2.2.7 You can view the QSOUND database file in the virtual voice software installation directory to check whether the correct voice parameter configuration is set for each counter.
2.2.8 If the voice becomes slower and slower, an independent sound card can be added.
2.2.9 In the case of a machine system that does not shut down for a long period of time, voice may become slower and slower.
2.2.10 The sound quality that is sometimes played is mostly related to the quality of the amplifier and the sound card itself;
It is a typical silicate material made of natural raw materials such as feldspar, clay and quartz. The main constituent elements are silicon, aluminum and oxygen. These three elements account for 90% of the total amount of crust elements. Low cost and mature technology. Such ceramics can be divided into daily-use ceramics, architectural ceramics, electrical insulating ceramics, chemical ceramics, etc. according to their performance characteristics and uses. It is made of high-purity synthetic raw materials and is formed by precision control process. It generally has some special properties to meet various needs. According to its main components, there are oxide ceramics, nitride ceramics, carbide ceramics, cermets, etc.; special ceramics have special mechanical, optical, acoustic, electrical, magnetic, thermal and other properties. According to different uses, special ceramic materials can be divided into structural ceramics, tool ceramics, and functional ceramics.
