Huating Shipyard, wharf.
The 7,000-ton ro-ro ship has been built and outfitted. All that is left is the final radio commissioning.
Factory Director Wang stood on the dock, looking at the brand new ro-ro ship with anxiety on his face.
The old Shanghai sedan drove directly onto the pier, and several people got out. When he saw them, Factory Director Wang finally breathed a sigh of relief: "You are finally here."
Among the several people, Zhang Dagang, the leader, said: "Director Wang, we are willing to do our best to help, but we have never been exposed to this set of equipment, and we are not sure in our hearts."
"You go ahead and do it. If it's broken, it's mine. If it's done, it's yours." Director Wang said.
Of course he knew the risks involved. This set of equipment was designated by the Belgian shipowner. The shipyard was only responsible for the installation and not the debugging. But now, the person responsible for debugging in the contract is not here, and the shipowner refuses to accept it. Boat.
The fire is burning, what should I do? Let's treat a dead horse as a live doctor. These technicians are all missile experts and have been exposed to many things, so they can definitely debug them.
Several people walked onto the bridge of the ro-ro ship and came to the front of the radio equipment.
In the initial age of navigation, ships did not have any communication equipment. If an accident occurred, they could only put a bottle in the bottle and hope to be picked up by other crew members. This probability was much lower than buying a lottery ticket.
Later, simple radio stations began to appear, but the power was not high. The distance for making calls was only tens of kilometers, but the distance for sending telegraphs could be thousands of kilometers. The international community also began to specify special frequency bands for ships to use.
By now, the ship's radio equipment has become a system and has clear requirements. Alarm, communication, radar positioning, and receiving maritime safety information must all have complete functions. In the future, when high-end global positioning systems and maritime satellite phones appear, these will also be necessary.
In order to meet these requirements, a reasonable combination is generally selected. Currently, the usual plan A used on this kind of Norwegian cargo ship includes a ship ground station, using direct printing telegraph to send and receive alarms, on duty, and using wireless telephone or DPT communication. A MF Installation (wireless radio) that meets DSC and wireless phone functions and DSC duty, meeting the needs of DSC alarm sending and receiving, wireless calls, and duty. There is also a device in the 406MHz frequency band that sends warnings of distress to the other side, which is implemented through specialized polar satellites.
These three devices are all installed in a cabinet. No one knows how to debug them.
"Give us the instructions." Zhao Dagang said.
"Here's the instruction manual." Someone immediately handed over the instruction manual.
Zhao Dagang took it over, opened the manual, and was dumbfounded.
Japanese? How can I use Japanese as an instruction manual? These guys clearly did this on purpose!
Generally speaking, the international language is English, and the instructions for machines exported by various countries are all written in English. Technicians like Zhao Dagang and others have learned English a long time ago and are in line with the world. When they go out to do exchange activities, they can converse in pure English without the need for translation.
However, knowing one foreign language is good, but other languages are difficult.
Looking at the Japanese explanation, Zhao Dagang was a little annoyed.
“Why are there no English instructions?”
"I don't know either." Carrasco, the pick-up representative sent by the Belgian shipowner, spread his hands, and then looked at his watch: "Now, it has been less than twenty-four hours since we picked up the ship. Please hurry up."
"Let's study the circuit diagram quickly." Zhao Ergang said.
Circuit diagrams are symbols that are used all over the world. There is no point in making a fuss about this. It is useless to talk to the other party now. It is better to quickly compare the circuit diagrams and study the circuit.
However, from front to back, there is only a wiring diagram and no detailed circuit diagram at all! What is this manual?
"Let's connect the wires." Zhao Dagang took a deep breath.
For input and output ports, you can try wiring them according to the wiring diagram.
Everyone held their breath. If the wrong line was connected and the equipment was burned, it would be all over.
Carrasco watched with interest as the cables were installed one by one. An hour later, Zhao Dagang let out a long breath: "Now, we can power on and test."
The gate of the circuit switch was closed by Zhao Dagang, and the switches were turned on one by one. Various indicator lights flashed. Zhao Dagang turned the knob of the radio station with his left hand, picked up the intercom with his right hand, and pressed the switch.
"This is the roll-on/roll-off ship that is about to be delivered by Huating Shipyard. I am requesting for network testing of radio equipment with Guangzhou Station. Please answer if you receive it. Please answer if you receive it!"
He released the switch, but no sound was heard. After waiting for another ten seconds, he pressed it again and called again.
Still no answer!
what happened?
Zhao Ergang looked at the display instrument on the radio station and frowned: "The frequency oscillator of the transmitter is not working!"
Regardless of any radio equipment, a frequency oscillator is required to provide the original signal, which is then modulated, loaded with sound or other signals, amplified and sent out. If the oscillator is not working, there will be no output at all.
"This equipment was broken when it left the factory!" Xu Qiang said: "It is impossible to debug at all! Even if we reorder the equipment and transport it from abroad, it will take a week or two. Because of this reason, the delivery is delayed, and it is not us. Responsibility!"
"NO, NO, NO!" Carrasco shook his head like a rattle: "No matter what the reason is, if you didn't deliver the ship on time, it's your responsibility. Even if there was a problem with the radio when it left the factory, it's because you didn't discover it early. "
"We are not responsible for debugging at all!" The young and energetic Xu Qiang was annoyed and said louder: "It was the Norwegian service provider who did not come for debugging. The responsibility is theirs! They will also pay the compensation!"
Factory Director Wang smiled bitterly at the side. They had already mentioned this point of view to the ship owner, but it was of no use.
"You are the general contractor. It is your responsibility to delay the delivery of the ship. You will pay the compensation. As for the Norwegian service providers, that is a commercial dispute between them and you and has nothing to do with us. In short, if the delivery time is delayed, we Just follow the contract." After saying that, Carrasco looked at his watch again: "It's less than twenty-two hours now. Instead of wasting time arguing with me, you might as well seize the time to fix it."
Repaired? How to fix it? The instruction manual is in Japanese and there is no detailed circuit diagram yet!
"It doesn't take twenty-two hours, two hours is enough." At this moment, a voice came from outside. A young man and two women came up from the gangway.
