Problems solved by technology

Updating is the process of replacing old equipment with new equipment. In the case of reorganizing the control panel and the equipment control devices such as cars and elevators are already established products, as long as the transmission protocol is not completely consistent, it cannot Problems with normal teleportation
Even if the physical layer, that is, the transmission line, transmission method, etc. are the same, but the transmission speed, transmission frame format, etc. are different, normal transmission cannot be performed even on the same transmission line.

no. 1 Embodiment

[0043] Next, refer to Figure 7 , to describe the frame conversion processing operation of the first embodiment of the present invention. When the reception of the transmission frame from the facility control device is started, in S702, the frame conversion processing unit judges whether or not the start bit of the received frame is detected. The start bit is detected, for example, by detecting a falling edge. If the start bit is not detected, the loop processing becomes a wait state until the start bit is detected. When the start bit is detected, in S704, the start bit is output to the main controller as transmission data. In S706, the input information data bit 7 (hereinafter, expressed as data bit 7, etc.), but since the master control device must send the identification bit before sending the information data, the input data bit 7 is stored in S708. Next, although the identification bit needs to be sent, the identification bit has not been received yet. The frame conve...

no. 2 Embodiment

[0049] Next, the frame conversion processing operation of the second embodiment will be described. This second embodiment focuses on the case where the length of information data included in a frame differs depending on the type of information data, and the frame conversion corresponding to the difference in the length of information data of different lengths. In this embodiment, by referring to Figure 10 Can deepen understanding. The frame conversion processing unit includes a reference clock generator having a frequency that is, for example, twice or more than the clock frequency of the input transmission frame. In addition, the frame conversion processing unit includes a frame length measuring device that counts the number of frames in one frame by, for example, starting the counting of the reference clock when the start bit is detected and ending the counting of the reference clock when the stop bit is detected. The count value of the included reference clock is counted...

no. 3 Embodiment

[0053] Next, refer to Figure 12 The flow chart shown in is an illustration of the frame conversion processing operation of the third embodiment of the present invention.

[0054] In addition, in Figure 12 , also about the Figure 7 The same processing as that in the flow chart showing the frame conversion processing operation example of the first embodiment of the present invention shown in Figure 7The same reference symbols as used in . From the reception of the transmission frame to the storage of the data bit 7 in S708, operations are performed in the same manner as in the first embodiment. Next, in S1209, the history data described later is referred to, and the output flag A' is set based on the history data and the stored transfer sequence. In addition, the history data in this embodiment is different from the history data in Embodiment 2 in content. For example, as the address frame #1 is transmitted first after system initialization, and the next input transmiss...

Abstract

The invention provides a transmission system and a method for an elevator system. In one embodiment, make a count value increase progressively when judging that frames received from a first device accurately performing frame transformation, and set identifiers indicating varieties of information data contained in the frames sent by the second device based on the count value. Via making a comparison of identifiers indicating varieties of information data contained in the frames received from the first device and the set identifiers, where frame conversion is accurately performed is judged.

Description

technical field [0001] The present invention relates to transmission of control data in an elevator system, and more particularly to a transmission system and method for an elevator system including a frame conversion device in the elevator system. Background technique [0002] Beginning with high economic growth, Japan's building construction market continues to grow with demand as a long-term trend. Among them, the aging of buildings and elevators is inevitable with the passage of time. In order to seek safety and comfort, the market for upgrading elevators is expanding. [0003] For an elevator system installed in a newly constructed building, it is necessary to implement all the components of the elevator, such as the construction of the elevator passage, the installation of guide rails and / or equipment in the elevator passage, the installation of the traction machine to the machine room, and the installation of the control device. Assembling, setting construction, the ...
