The radio transmitter 34 is configured to be able to emit information (and in particular orders, commands or alerts) in the form of radio waves OE2 intended for the hydrocleaner 2, in particular to trigger an alert element or to take control of a piece of equipment of the hydrocleaner as stated hereinbelow.

The transmission between, on the one hand, the radio transmission unit 8 of the hydrocleaner 3 and, on the other hand, the radio transmission unit 32 of the control station 29, is secure.

The remote control unit 31 comprises a set of means that make it possible to inform and alert persons 40 and 41 (FIG. 6) installed (remotely from the worksite) at the control station 29 of an anomaly. These persons 30 and 31 are employed to remotely monitor both the operator, the hydrocleaner and the worksite, and to intervene remotely if necessary.

These control orders are intended to remotely control at least one piece of equipment of the hydrocleaner, for example stop it is case of malfunction or danger.

The control orders are emitted by the radio transmission unit 32 of the control station 29 and received by the radio transmission unit 8 of the device 1 which transmits them to a control element 24 of the hydrocleaner 3 or to a control element 25 of a piece of equipment of the hydrocleaner 3.

The persons who remotely monitor the worksite, in particular the technician 40 (for technical support and monitoring) and the doctor 41 (for medical support and monitoring), are therefore informed in real time of any anomaly, danger or accident occurring on the worksite and can intervene remotely.

They have various means of intervention, that they can use according to the problem detected. In particular, they can trigger an alert on the worksite and they can also take control of a piece of equipment of the hydrocleaner, and in particular shut it down.

They also have one or more intervention vehicles 43 (FIG. 6) allowing a technician or a doctor to go to the worksite, if it is not too far away. The intervention vehicle 43 is in particular provided for proximity medical assistance.

The system 30, such as described hereinabove, makes it possible to monitor, from the control station 29, simultaneously a plurality of hydrocleaners working on the same site or on different sites that are far from one another.

The system 30 makes it possible to monitor any type of work carried out by the operator 3 with the hydrocleaner 2.

For the purposes of illustration, the hydrocleaner 2 such as shown in FIG. 2, comprises a pumping system 46, a water tank 47 for carrying out cleaning operations, and a collection tank 48 for collecting products pumped by the pumping system 46. II also comprises a suction hose 49 (for the pumping) and a high-pressure hose 50 (for cleaning). The hydrocleaner 2 thus comprises a set of operations equipment that makes it possible to perform pumping and cleaning operations. The hydrocleaner 20 further comprises the radio transmission units 5 and 8, alert elements, and sensors of sets 20 and 21, of which only one CC1 is shown in FIG. 2.

In the example of FIG. 2, the operator 3 is sucking products, for example oil products, via the suction hose 49. These products are sucked into the collection tank 48 of the hydrocleaner 2.

FIG. 5 shows another example of the work of the operator 3, with the hydrocleaner 3 of FIG. 2. In this example, the operator 3 is performing cleaning work using a high-pressure gun 51 supplied by the high-pressure hose 49 of the hydrocleaner 2.

For the purposes of illustration, non-limiting, mentioned is made hereinafter of different particular situations that can occur, and the monitoring, actions and/or interventions that can be performed in these particular situations.

Firstly, in case of a fall of the operator 3 on the worksite, as the operator 3 is constantly monitored thanks to the sensors incorporated into the piece or pieces of clothing 12 that they are wearing, the control station 29 is informed of this falling, via the low-frequency connection between the equipment of the operator 3 and the hydrocleaner 2 which is, itself, in liaison with the remotely-located control station 29.

Secondly, to respond to a risk of a dangerous atmosphere, at least one sensor worn by the operator 3 and at least one sensor installed on the hydrocleaner 2, inform the control station 29, which allows, instantly, if necessary, for taking control either medically or with regards to the equipment.

Thirdly, in case of abnormal operation at the hydrocleaner 2 (abnormal rise in temperature of the motor of the hydrocleaner 2 or of a pumping system 46, loss of oil pressure of the motor of the hydrocleaner 2 or of the drive of the pumping system 46, abnormal speed of the motor of the hydrocleaner 2 or of the pumping system 46, failure of the filling level of the collection tank 48, loss of equipotentiality of the suction line), the technician 40 of the control station 29 is informed, and they carry out the suitable actions such remotely taking control, and in particular shutting down the defective equipment.

Fourthly, in case of the bursting of a hose or a tool, the control station 29 is informed thanks to the monitoring of the entire line. If a sudden rupture in pressure is detected while the pump is delivering, the latter is automatically stopped. The state (medical) of the operator is also monitored by the control station 29.

Fifthly, when an operator is injured by the works, the constant monitoring of the operator 3, in particular at the heart level, immediately reports the accident, and the installation is shut down. At the same time, the doctor 41 in the control station 29 takes over the medical situation of the operator 3.

Consequently, in the control station 29, at each alert, a technician 40 and a doctor 41 provide the suitable technical support, even take control of the equipment, and the correct medical response with, if necessary, sending a team of rescue workers to the worksite.
