The interior circulation cooling water route 4 is additionally provided with pressure-regulating valve 42, for controlling the interior outflow of circulation cooling water route 4
Hydraulic pressure value.
Pressure heating control 10 is additionally provided in the people cabin 1, pressure heating control 10 issues control instruction to control
Device 9 processed, then control water heating system 81 open/closing and control opening for ball valve 71/close, it is ensured that when the temperature in people cabin 1 without
When method meets the requirement of personnel in people cabin 1, heating control 10 can be forced to be cut come the mistake water lines 5 made one in cabin 1 by starting
The second heating water route 8 is shifted to be heated.
The invention also discloses a kind of in people cabin for the control method of shield machine people cabin heating system, uses the control
Method installs additional not in people cabin and forces heating control 10,
As the pressure P ＞ external atmosphere pressure P in people cabin 1,
Situation 1：The temperature t1 in the interior circulation cooling water route 4 >=systemic presupposition temperature t, minimum temperature T1≤t in people cabin 1
Maximum temperature T2 in≤people cabin 1, and maximum temperature T2 in t1 >=people cabin 1, the at this time highest temperature in the temperature T ＜ people cabin 1 in people cabin 1
T2 is spent, the control device 9 issues control instruction to control ball valve 71, control ball valve 71 is switched to open state, people cabin 1
Interior 51 default situations of first manual ball valve are in open state, and the mistake water lines 5 and first in people cabin 1 heat water route 7 at this time
Conducting, the heating of people cabin 1 carries out heat supply using interior circulation cooling water route 4, until maximum temperature in temperature T >=people cabin 1 in people cabin 1
T2, at this time control device 9 issue control instruction to control ball valve 71, will control ball valve 71 switching be in off state；
Situation 2：Maximum temperature T2 in the temperature t1 ＜ people cabin 1 in the interior circulation cooling water route 4, at this time the temperature T in people cabin 1
Maximum temperature T2 in ＜ people cabin 1, the control device 9 issue control instruction to control ball valve 71, control ball valve 71 are switched
It is in off state, 51 default situations of first manual ball valve in people cabin 1 are in open state, at this time the mistake water lines 5 in people cabin 1
It is connected with the second heating water route 8, control device 9 issues control instruction to water heating system 81, opens water heater 811 and pumping
Device 812 carries out pumping heat supply, until people cabin 1 in temperature T >=people cabin 1 in maximum temperature T2, at this time control device 9 issue control
Instruction closes water heater 811, when the temperature T in people cabin 1 is gradually reduced to T1, under control device 9 to water heating system 81
Control instruction is sent out to water heating system 81, reopens water heater 811, so that it is guaranteed that the temperature T in people cabin 1 is in T1 always
In≤T≤T2 interval ranges；
As pressure P=external atmosphere pressure P in people cabin 1, the control device 9 issues control instruction to control ball valve 71, will control
Ball valve 71 processed is switched to open state, and water heating system 81 is closed at this time, and the personnel in people cabin 1 are by artificially controlling
First manual ball valve 51 opens/close or people cabin 1 outside personnel by artificially controlling opening for the second manual ball valve 75/close, to
Realize that the temperature in people cabin 1 can heat as needed；
Certainly in these cases, when setting first manual ball valve 51 in people cabin 1, the personnel in people cabin 1, which work as, experiences people cabin
Inside when the temperature is excessively high, default situations first manual ball valve 51 in the open state can be closed, to which interior mistake is accessed in people cabin 1
First heating water 7 or second of water lines 5 heats the heat source cut-out in water route 8, if it is the second heating to access water lines 5 at this time
When water route 8, then control device 9 issues control instruction to water heating system 81, closes water heater 811 and pump feeder 812.
The invention also discloses another kinds to install the control that the shield machine people cabin heating system of control is heated in pressure additional in people cabin
Method processed,
As the pressure P ＞ external atmosphere pressure P in people cabin 1,
Situation 1：The temperature t1 ＞ systemic presupposition temperature t in the interior circulation cooling water route 4, minimum temperature T1≤t in people cabin 1
Maximum temperature T2 in≤people cabin 1, and maximum temperature T2 in t1 >=people cabin 1, the at this time highest temperature in the temperature T ＜ people cabin 1 in people cabin 1
T2 is spent, the control device 9 issues control instruction to control ball valve 71, control ball valve 71 is switched to open state, people cabin 1
Interior 51 default situations of first manual ball valve are in open state, and the mistake water lines 5 and first in people cabin 1 heat water route 7 at this time
Conducting, the heating of people cabin 1 carries out heat supply using interior circulation cooling water route 4, until maximum temperature in temperature T >=people cabin 1 in people cabin 1
