2. Description of Related Art
In present society and system, economic benefit and cost-effectiveness are emphasized, and all industries including the light industry, the heavy industry and service industry have common objectives of reducing manpower and improving productivity, and thus automated productions or automated processes become one of the effective feasible solutions for reducing the manpower, improving the operating safety and economic effectiveness. For instance, a general manufacturing industry adopts a large number of automated equipments for the production line to improve product quality and lower costs, and the automated equipments can be operated in poor working environments such as a paint spray room, a working room operated at abnormal temperatures or any environment not suitable for people to work for long hours. Further, these automated equipments can work for us for a long time, if the equipments are maintained appropriately.
Although the automated equipments have the aforementioned advantages, it is not easy to maintain the operation of these automated equipments to a quality level up to our expectation. Therefore, it is very important to control automated equipments properly, and the precision of controlling automated equipments plays an important role in product quality. For existing control components, a personal computer is generally used for controlling a programmable logic controller to send an instruction or a program to the automated equipment, so that the automated equipment can be operated according to the instruction. However, the aforementioned programmable logic controller cannot be operated independently or solely, but is operated with a synchronized personal computer. Therefore, users have need to reserve a place for installing the personal computer in order to use the automated equipments, and users also need to connect and install wires and cables, and thus incurring an additional cost.
The programmable logic controller available in the market has become a mainstream, and users can input an editing program instruction in a memory module of the programmable logic controller, such that the programmable logic controller can generate corresponding control logic to control external output devices. In general, a command of the programmable logic controller requires initial values, system parameters and interrupts to set related input and output switches. Unless users are familiar with the related program instructions, users need to check program instructions and their operations one by one in a user's guide d to code a program. Beginners usually end up with a missing instruction or a programming error that may cause tremendous problems to the operation of the output devices.
In view of the shortcomings of the prior art, it is a subject for manufacturers of the related industry to find feasible ways of simplifying the setup of a programmable logic controller, lowering chance of making a programming error, improving the accuracy and reliability of editing a program, cutting down the development cost of existing systems, and designing an independent programmable logic controller.
Therefore, it is a primary objective of the present invention to use a menu display module to set a menu control instruction, so that users can set corresponding menu control instructions without the need of learning the difficult syntax of the program. Users can set up a programmable automatic triggering system in a simple and easy manner, so that errors occurred in the programming editing and setup procedure can be reduced significantly, and the manufacturer's acceptance can be enhanced effectively.
The secondary objective of the present invention is to maintain a good communication between the automation and its users through the exchange of messages or communication with the automatic triggering apparatus via mail, SNMP or active messaging, if an external input/output device is connected to the automatic triggering apparatus and specific conditions are satisfied.
To achieve the foregoing objectives and effects, the objectives, structure, innovative features, and performance of the present invention will be apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

The core technology of the present invention applied in a traditional building automated system is illustrated here. A general building adopts the concept of using a plurality of remote input/output devices for the design of the building, and all events and responses are controlled by a computer in an engine room through a transmission interface. If there is any usual situation or emergency, the personnel or computer in the engine room will issue an instruction to the external input/output device to execute a certain operation, such as turning on a heat dissipating fan if the temperature is too high, lighting up a warning lamp if the safety door is opened abnormally, or starting an automatic sprinkler system if the temperature exceeds a predetermined fire protection temperature. Since all these are urgent operations, we can reduce the chance of accidents and minimize the loss, if related measures and operations can be started timely. Therefore, a user may connect a micro switch to a digital input of an input/output device at a remote end and install the micro switch on a desired monitoring and controlling door and connect a buzzer to a digital output of the input/output device at the remote end, such that if the door is opened, the buzzer will be triggered and a series of operations will be completed within a few milliseconds, so as to give a quick response. Besides the surveillance for the door security, the temperature and humidity also can be monitored and controlled by the programmable automatic triggering system of the present invention.
Therefore, the aforementioned input/output menu control instruction mode can be used as a trigger condition for turning on/off a power supply or computing the numeric value of a counter or timer.
Further, the corresponding operation of the input/output menu control instruction can be a control of turning on/off or pausing the power supply of an input/output device, or an exchange of messages or a communication via mail, SNMP or active messaging. The foregoing programmable automatic triggering system can be used in a desktop computer, a portable computer, an industrial computer, a server, a personal digital assistant or any device with computing and storing functions.
In summation of the description above, the present invention have the following advantages over the prior art.
(1) The present invention adopts a menu control instruction of the menu display module 11 and an output menu control instruction corresponding to the input menu control instruction, so that a user can sequentially set a menu control instruction without the need of learning difficult syntax of programs, and also can set the programmable automatic triggering system in a simple and easy manner, so as to enhance the manufacturer's acceptance significantly.
(2) The program instruction display module 12 is provided for displaying a menu control instruction that is set by the menu display module 11 and a human-like logic is adopted for displaying the menu control instruction, so that users need not to compare the difficult program codes 22 one by one to determine and confirm the accuracy of setting the menu control instructions, and thus greatly reducing human mistakes and programming, editing or setup errors.
(3) After the program code generating module 13 sends the compiled program codes 22 to the automatic triggering apparatus 2, the automatic triggering apparatus 2 can be interacted independently with the external input/output device without the need of synchronously connecting the server, such that we can save the place for installing the servers including personal computers or industrial computers when the programmable automatic triggering system and apparatus of the present invention is used. Therefore, the present invention allows a more flexible wiring layout and achieves the dual effect for a distributed processing and a central management.
(4) If the preinstalled external input/output device that is connected to the automatic triggering apparatus 2 satisfies certain specific conditions that are set by the menu control instructions, the automatic triggering apparatus 2 will perform an exchange of messages or a communication via mail, SNMP or active messaging, so as to maintain a good communication between automation and users.
