A simple elevator control system can be provided.

  Hereinafter, an embodiment of an elevator control system according to the present invention will be described with reference to FIGS.

  In FIG. 1, the elevator control system 1 includes at least an elevator control panel 3 that is connected to the Internet 2 and controls the elevator, and a communication terminal device 4 that is connected to the Internet 2. The elevator control panel 3 has a control unit 5 and is installed in an elevator machine room or an elevator hoistway. The communication terminal device 4 includes a personal computer or a mobile phone held by a maintenance engineer of an elevator maintenance company or a general manager such as a building owner or a building manager of a building where the elevator is installed. The control unit 5 includes a WWW communication processing unit 6, a first storage unit 7 that stores variable software that can be changed by the communication terminal device 4 of the elevator control software, and a communication terminal of the elevator control software. It comprises a second storage unit 8 that stores invariant software that cannot be changed by the device 4 and an operating system unit 9.

  The communication terminal device 4 has a function of displaying a home page on the Internet 2 and a function of creating elevator control software. Elevator control software is created by the communication terminal device 4 using a high-level language for personal computers such as C language, and general management for building owners and building managers of the building where the elevator is installed, other than the maintenance engineer of the elevator maintenance company It can be easily done by a person. The communication terminal device 4 has a function of creating variable software that can be changed by compiling the source code 10 shown in FIG. 3, and a screen that simulates an elevator in order to check the operation of the elevator by the created variable software. Above, it has a function that can simulate the operation of the elevator by the variable software. Further, when the variable software stored in the first storage unit 7 of the control unit 5 is changed (updated) to the variable software created by the communication terminal device 4, the WWW communication processing unit 6 Safety measures should be implemented to prevent outsiders other than the maintenance engineer of the elevator maintenance company and general managers such as the building owner and the building manager who installed the elevator from seeing the changed variable software. It has been subjected.

  The first storage unit 7 of the control unit 5 stores control software relating to service floor control, service control such as on / off operation, display control such as floor display change, and announcement content change as variable software. Yes. Control software related to safety control, speed control, and abnormality monitoring is stored in the second storage unit 8 of the control unit 5 as invariant software.

  The operating system unit 9 of the control unit 5 has functions of managing program processes and tasks and interfacing with external devices. The operating system unit 9 stores elevator control software when the elevator control panel 3 is shipped from the factory. Even after the variable software of the elevator control software is changed, the operating button (not shown) provided on the elevator operation control panel or the operation button (not shown) provided on the communication terminal device 4 is operated to operate the operating software. The elevator control software stored in the system unit 9 can be returned to the elevator control software at the time of factory shipment.

  In the elevator control system 1 configured as described above, for example, when an elevator destination button is pressed, the corresponding variable software stored in the first storage unit 7 is read out by the operating system unit 9 of the elevator control panel 3, The elevator is operated and controlled by the variable software. When an accident such as a passenger being trapped in the elevator car occurs while the elevator is operating with the variable software read out from the first storage unit 7, it is read out from the first storage unit 7. The elevator operation control by the changed variable software is stopped, and the rescue operation software out of the invariant software stored in the second storage unit 8 is read, and the elevator is controlled by the rescue operation software. .

  Next, for example, a description will be given of a case in which the elevator is remodeled, such as “Getting into the elevator and pressing the destination button on the fifth floor stops once on the third floor”. In addition, in order to temporarily stop on the third floor with the modified version of this elevator, the call for the lift platform on the third floor is registered.

  In this elevator remodeling specification, the source code 10 shown in FIG. 3 includes a C language remodeling source code 11 “if (posi (1) <3 && cage (1,5)! = 0) hall_up (3, ON);”. Add The special function “if (posi (N)” in the modified source code 11 indicates the position of the elevator of Unit N, and the special function “cage (N, X)” indicates that the destination button on the X floor of the elevator of Unit N is not registered. The special function “hall_up (X, Y)” represents Y = ON (registration) / OFF (registration cancellation) for the X-th floor lift landing call.

  The modified source code 11 “if (posi (1) <3 && cage (1,5)! = 0) hall_up (3, ON);” is added to the source code 10 shown in FIG. When the destination button on the fifth floor of the elevator is registered below the third floor, it operates so as to register the lift hall call on the third floor, resulting in the above-mentioned modified specification.

  The special function is an internal function of the operating system unit 9, and data related to variable software stored in the first storage unit 7 is input / output based on the internal function. In addition to the special function, the internal function includes a function for performing audio broadcasting in the elevator, a function related to the speed of the elevator, a function related to the door state, and the like. For example, if a remodeled source code “if (posi (1) == 2 && speed (1) == 0 && door (1) == OPEN) annai (“ homewa, suberuiinode, gochu ikusai ”); When the car door is open after arriving at the floor, it is possible to repeat the broadcast that “Please note that the platform is slippery.”

  Next, the communication terminal device 4 compiles the source code 10 shown in FIG. 3 to which the modified source code 11 is added, and transmits the created variable software to the elevator control panel 3 via the Internet 2. By changing (updating) the corresponding variable software stored in the first storage unit 7 to the transmitted variable software, the elevator is operated based on the variable software created by the communication terminal device 4. Can be controlled.

  According to the above embodiment example, variable software among the elevator control software of the elevator control panel 3 can be created from the source code 8 by the communication terminal device 4 and can be changed via the Internet 2. The operation control of the elevator can be changed without being restricted by the elevator control software at the time of factory shipment of the panel 3. In addition, the operation control of the elevator is not limited to the maintenance engineer of the elevator maintenance company, but the general management of the building owner or the building manager of the building where the elevator is installed by operating the communication terminal device 4 It is possible even by a person.

  Furthermore, according to the above embodiment, instead of making all of the elevator control software of the elevator control panel 3 changeable by the communication terminal device 4, the control software related to safety control, speed control, and abnormality monitoring is made invariant software, In addition, by classifying the control software related to service floor control, driving on and off work, changing the floor display, and changing the contents of announcements as variable software, only communication software related to the variable software is created by the communication terminal device 4. Therefore, the safe operation of the elevator is ensured without changing the invariant software such as the control software related to the safety control, the speed control, and the abnormality monitoring, which is safe.

  Furthermore, according to the above embodiment, after confirming the elevator operation confirmation by the variable software created by the communication terminal device 4 by the communication terminal device 4, the variable software created by the communication terminal device 4 is transmitted. Therefore, since it is possible to prevent defective variable software from being transmitted to the elevator control panel 3, it is safe and convenient.

  Further, according to the above-described embodiment, when a malfunction occurs in the operation of the elevator by the variable software, the variable software is disconnected and the rescue operation software stored in the second storage unit 8 rescues the elevator. Since driving is performed automatically, it is safe.

  Further, according to the above-described embodiment, even after changing the variable software of the elevator control software, the elevator control panel can be operated by operating the operation button provided on the elevator operation panel or the operation button provided on the communication terminal device 4. It is convenient because it is possible to return to the elevator control software at the time of factory shipment.

  Furthermore, according to the communication terminal device 4 of the above embodiment, the C language source code 10 makes it easy to understand even if it is not a software expert, and there are no restrictions on the algorithm. Can be created. For example, when there are multiple elevators, control software that determines which elevator responds to which floor call must be created by the general manager such as the building owner or building manager of the building where the elevator is installed. Is possible. Therefore, the variable software stored in the elevator control panel 3 is installed on the general manager side such as the building owner or the building manager of the building where the elevator is installed so that the elevator operation can be performed in accordance with the usage status of the elevator in each building. Since it can be changed, the convenience of building users can be improved without bothering the maintenance engineer of the elevator maintenance company.
