By way of judging that electric signal is strong and weak, to detect the specific size of hydraulic pressure value；It is more than in order to prevent that pressure is examined because pressure is excessive
The range for surveying device, during detecting pressure in pipe under test, pressure information that pressure-detecting device can will test
It first exports to the second judgment component, after the second judgment component completes pressure information judgement, if be not above default
Value, then the pressure information is transmitted in pressure-detecting device in the component of size for judging hydraulic pressure value again, to detect
The occurrence of the pressure information out；If the second judgment component judges the pressure information beyond preset value, by connecting therewith
The the second control element control data transmission device connect transmits the first warning message, and then staff is made to understand this pressure monitoring
The hydraulic pressure value of the pipe under test of equipment position is excessive, and takes corresponding solution in time, this can prevent pressure
Detection device is impaired, can also reduce the incidence of safety accident.Specifically, range can be used greater than pressure-detecting device
Second judgment component, and in order to save cost, can select the second judgment component that precision is relatively low, and above-mentioned preset value can be with
It is maximum that slightly smaller than pressure-detecting device also can be set into equal to the value of the maximum range of pressure-detecting device or the preset value
The numerical value of range.
It is known that whatsoever pipeline, the hydraulic pressure value that can bear generally in certain section, thus for
For test tube road, the limiting value of pressure bearing there will necessarily be, hydraulic pressure value exceeds the pressure bearing limiting value of pipeline in order to prevent
Cause pipeline burst；Meanwhile manifold pressure is inadequate or anhydrous and be unable to complete liquid conveying task or the fire that disappears is anti-in order to prevent
The case where calamity, further, pressure-detecting device provided herein can also include hydraulic pressure value prior-warning device, and hydraulic pressure value is pre-
Alarm device is electrically connected with pressure-detecting device and data transmission device, and hydraulic pressure value prior-warning device may include the interconnected
Three judgment components and third control element；In the course of work of pressure monitoring devices, third judgment component may determine that pressure
Whether whether hydraulic pressure value measured by detection device is greater than preset upper pressure limit value, and/or be less than under preset pressure
Limit value, and judging result is exported to third control element；Correspondingly, it is greater than in aforementioned pressure in measured actual hydraulic pressure value
Limit value, or be less than aforementioned pressure lower limit value when, third control element can control data transmission device transmit the second warning message.
Specifically, similarly with over range prior-warning device, hydraulic pressure value prior-warning device is by judging hydraulic pressure measured by pressure-detecting device
The size of value, if the value beyond preset pressure bound, and in measured hydraulic pressure value when exceeding pressure upper lower limit value,
Data transmission device is controlled by the second control element and transmits the second warning message, and staff is receiving the second warning message
When, the hydraulic pressure value at available pipe under test transfinites this information, then can be suitably decreased or increased according to the information to
The flow of liquid at test tube road, realization remotely monitor and solve the problems, such as that pressure limit or pressure are inadequate,
Further, for the transmission working efficiency of improve data transfer device, and in order to reduce data transmission device
The number of starts, to improve its service life, it is preferred that pressure-detecting device provided herein can also include that second prolong
When control device, the second overrun control can be electrically connected with data transmission device, and the second overrun control may include
Second time detecting element, the 4th judgment component and the 4th control element, and three is electrically connected to each other, the second time control components
It can detecte the second duration that data transmission device is under stop working state, and the second duration exported to the 4th judgement member
Part to judge whether the second duration is equal to the second preset duration by the 4th judgment component, and is equal to second in advance in the second duration
If when duration, controlling data transmission device by the 4th control element and entering working condition, that is, carry out to measured number pressure
According to transmission work.Specifically, the second overrun control may be the devices such as time-delay relay, pass through the second delay of setting
Control device makes data transmission device also can periodic duty；Those skilled in the art can period determines according to actual conditions
The size of value, specifically, the value of the second preset duration can be greater than or equal to the first preset duration, and preferably the second preset duration is big
In the first preset duration, more specifically, when data transmission device is in and stops working, pressure-detecting device can will be measured
Hydraulic pressure value be buffered in data transmission device, when data upload the period reach when, data transmission device can will before store
Multiple groups hydraulic pressure value (i.e. different time points when pipeline in hydraulic pressure value) data transfer out, data transmission device can be improved in this
Working efficiency, and the service life of data transmission device can be extended, can also extend battery uses the time.
Further, it is contemplated that data transmission device may be caused to cannot proceed normally data biography because of factors such as network fluctuations
Defeated work causes the imperfection of data, it is preferable that this Shen to cause staff that can not understand and record the secondary data
It please be also provided with upload monitoring device in provided pressure monitoring devices, upload monitoring device and data transmission device electricity
Connection, is used for whether detection data transmitting device successfully to transfer out by data and (be such as transmitted to monitoring system), and, when
When data transmission device can not carry out data transmission work, upload monitoring device can recorde tool when such as this time data transmission
The body moment, failure cause etc., and control data transmission device itself or other devices will be under the data storages of transmission needed for this
Come, when data transmission device carries out data transmission work next time, upload monitoring device controls data transmission device again will be upper
The data of secondary non-transmission success and this time the data sent is needed to transfer out together；Alternatively, in some cases, can control
