On improving the function of ICS 200/60 system, the concept of the words


Rate, complete enough, there is no need for expansion. Although the use to the tune of Qingyang District, Xining, Yinchuan, Georgia child wood, Jiuquan and Dunhuang, Hanzhong, Minqin, remote control units in nine yabrai as well as the field frequency of 124.1 prepare, prepare frequency 120.95, Emergency preparedness frequency 121.5, military aircraft 130.0, MG-23016, YL'16616, HF11342 and MG'18897 total of 18 frequencies. However, if the front end of the comparison device, the Dunhuang, Dunhuang-based wood lattice children; this field, Minqin, Xining, Qingyang to Minqin based. As a result,[link widoczny dla zalogowanych], the actual use of 13 frequencies, together with sub-seat when the busy route, so the short term without extension. On the other hand, even if the seat is not enough, need to expand, due to its distributed properties of the layout can be easily extended to seat 25, so do not worry. 'd CB, PSTN and other telephone resources are not fully utilized,[link widoczny dla zalogowanych], very unfortunate. May consider appropriate to be developed and utilized. 4. Lanzhou control interface module according to the planning division of the regional sector, Lanzhou control zone will be divided into 01 sectors and 02 two, add Dangchang, tea cards, Tuotuohe VHF remote control units, while increasing the frequency of the two prepared, The five frequency plus the original 21 frequencies, 26 frequencies. The existing wireless interface card can access a total of 30 frequencies. Therefore, the wireless interface card has not expanded. As for the cable interface card, the existing resources are sufficient to ensure that the next 5 to 10 years of use. 5. Lanzhou ICS200/60 wiring system installation is not configured in the front patch panel, based on years of use, maintenance experience, I think this is a mistake. This point, with the original S. I. T. T. I compared the words of the regression. If the system is in the main cabinet in the back of the jumper installed to replace the front frame distribution frame function. At first glance, saving a cabinet, but also out of line in shorter words, but in fact they are more harm than good. First of all, the jumper from the host stand too close,[link widoczny dla zalogowanych], when the inevitable bumps in the wiring, increased. The probability of malfunction; Second, patch panels, cabinets installed in the -1, so that the already limited space even more crowded, messy, despite repeated sorting, but to no avail. If you install the front patch panel, then the problem can be easily described _ resolve divination, although some lines to extend a few meters, but compared to the safe operation of equipment, which then what of it? In addition, the maintenance of the system workstations via Ethernet connected with the server, the original is set to connect multiple workstations. Very good idea, but becomes a lot more than in Lanzhou,[link widoczny dla zalogowanych], a (Figure 1). Placement of the bridge had no place, very casual with a tie fixed to the back of the cabinet, the need for power supply, it is asking for trouble, it is better to cancel the bridge, the workstation's Ethernet interface directly with the server connection Qi not better? 6. Power system power of the machine as the blood in the human body, essential for a moment, an unstable power system will bring Ji Wuyuan endless trouble. August 17, 2002 and December 3, Lanzhou ICS200/60 system twice a power outage, caused by ground / air communication interrupted ten minutes, had to enable the emergency equipment. The reason is simply the power junction box on a small screw loose, causing ignition, so that the wall air switch trip, leading to system power. Temptress Moon ■ IlII1 ● ● ● Jl turned a K capsule '■ into the' why a small screws caused so much trouble? The power supply system from about the system (Figure 2). From the figure we can clearly see the back of the main cabinet with two perpendicular to the ground five-wire power cord, the device's power supply by the two lines, each cabinet is to take power from the junction box, from five two screws. This connection, the advantage is to facilitate sub-lines, while the relative isolation of the cabinet, independently of each other. But the problem is caused by too many contacts, fixed is not strong. It is because of the long-term force small screws, resulting in loose, sparking phenomena caused by tripping off. As a solution, we then install a power module (dotted line shown in Figure 2), while two have left and right input. But I think that screw ignition problems and not completely solved, who can be sure electricity is not the same time two ignition trip. To solve the problem, a minor operation needs to be done: to install copper wiring nose first, set the screw, so that you can prevent ignition from occurring, to prevent the walls of the air switch trip. If long-term perspective, consider changing the access mode of the system's power, but this action must obtain the consent and cooperation of manufacturers, we can not achieve.
