Description
本發明是有關於一種區域管制系統及其定位方法,特別是指一種用於定位一作業區域內的作業人員及危險機具之相對位置的區域管制系統及其定位方法。 The invention relates to a regional control system and a positioning method thereof, in particular to a regional control system for locating the relative positions of workers and dangerous implements in a work area and a positioning method thereof.
熱軋鋼廠的作業儲區是用於將多個鋼捲分層堆疊儲放,由於每個鋼捲重達20公噸,故需使用天車來吊運該等鋼捲以滿足鋼品的調度需求。而作業人員的工作便是在堆放有大量鋼捲及天車穿梭其中的作業儲區內來回巡檢,以檢驗鋼捲的品質或盤點數量。大量堆疊的鋼捲使作業人員僅能於鋼捲堆間的間隔走道中行進,且尚需警覺天車動向,避免天車在吊運鋼捲時因發生鋼捲掉落而產生工安問題。在無法確切得知天車即時位置及作業人員資訊的情況下,不但容易發生前述工安意外,位於作業儲區外的控管中心也難以掌握現場的即時資訊及人員位置,因而無法快速地給予作業人員適當且即時的指示,降低作業效率。 The working storage area of the hot-rolled steel mill is used for layering and stacking multiple steel coils. Since each steel coil weighs 20 metric tons, it is necessary to use the crane to lift the steel coils to meet the scheduling requirements of the steel products. . The job of the operator is to patrol back and forth in the working storage area where a large number of steel coils and cranes are shuttled to check the quality of the coil or the number of stocks. A large number of stacked steel coils enable the operator to travel only in the spaced walkways between the coil stacks, and it is necessary to be alert to the movement of the overhead crane to prevent the crane from causing work safety problems due to the falling of the steel coil when lifting the steel coil. In the case where the real-time location of the crane and the information of the operator cannot be known accurately, it is not only easy to cause the above-mentioned industrial safety accidents, but also the control center outside the working storage area is difficult to grasp the real-time information and personnel position on the site, so it cannot be quickly given. The operator's appropriate and immediate instructions reduce the efficiency of the work.
因此,本發明之目的,即在提供一種可供控管人員定位一作業區域內的作業人員及危險機具之即時位置的區域管制系統。 Accordingly, it is an object of the present invention to provide a zone control system for a controllable person to locate the immediate position of an operator and a dangerous implement within a work area.
於是,本發明區域管制系統,用於供控管人員定位一作業區域內的複數作業人員及至少一危險機具。該區域管制系統包含複數分別配置於該等作業人員身上的移動式裝置、複數分別配置於該等作業人員身上以定位該等作業人員的第一人員定位裝置、至少一設置於該危險機具上以定位該危險機具並可對該危險機具提出警示的機具定位裝置,及一供控管人員監控的監控裝置。 Thus, the regional control system of the present invention is for the control personnel to locate a plurality of workers and at least one dangerous implement in a work area.

During the inspection process, when any of the objects to be detected E changes the placement position due to the operation demand, the worker C can query the mobile device 2 and immediately grasp the instantaneous position of the corresponding object to be detected E, thereby improving the work efficiency. . When the distance between any of the first person positioning devices 3 and any of the implement positioning devices 5 is less than a safe range of about 40 meters to 60 meters, the alert unit 82 of the monitoring device 8 will alert the controller, and The alarm unit 22 of the corresponding mobile device 2 issues a warning, and also issues a warning to the corresponding implement positioning device 5, so that the light-emitting diode warning module and the voice warning module of the corresponding dangerous implement D are activated. Avoid work safety problems. When any worker C enters and exits the control area, the area positioning device 7 disposed in the control area is sensed by the second person positioning device 4 disposed on the body, and the information of the worker C is transmitted to the monitoring device 8 to Conduct personnel and regional controls.
透過前述的定位方法可不需使用GPS以克服熱軋鋼捲儲區不利於GPS通訊之問題。藉由該等待測物定位裝置6可隨時更新該等待檢測物E的即時位置,故當該等待檢測物E位置更動時,該等作業人員C不需回該管制中心A重新查詢,且藉由該等移動式裝置2可即時將檢驗結 果及人員位置回傳至該管制中心A,以利該管制中心A即時進行指令下達或管控,並透過該第一人員定位裝置3及該第二人員定位裝置4進一步掌握人員位置,避免誤入該等危險機具D的作業範圍而發生工安問題。 Through the aforementioned positioning method, GPS can be used to overcome the problem that the hot-rolled steel coil storage area is not conducive to GPS communication. The waiting position of the waiting object E can be updated at any time by the waiting object positioning device 6, so when the position of the waiting detecting object E is changed, the workers C do not need to return to the control center A to re-query, and by The mobile device 2 can immediately verify the knot And the position of the person is transferred back to the control center A, so that the control center A can immediately issue instructions or control, and further grasp the position of the person through the first person positioning device 3 and the second person positioning device 4 to avoid mis-entry. Safety problems occur in the operating range of these dangerous implements D.
綜上所述,前述配置可使該管制中心A內的控管人員透過資訊整合即時掌握該作業區域B內的現場狀況,以能快速地下達指示,提高作業效率並避免工安問題,且依據不同的需求能彈性地增減裝置,提升泛用性,故確實能達成本發明之目的。 In summary, the foregoing configuration enables the control personnel in the control center A to immediately grasp the on-site condition in the work area B through information integration, so as to quickly reach the instructions, improve the work efficiency and avoid the work safety problem, and Different requirements can flexibly increase or decrease the device and improve the generality, so that the object of the present invention can be achieved.
